    Att vänja sig vid smärta: En behandlingsstudie av patienter med långvarig smärta2008Independent thesis Basic level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Current research has shown that psychological factors play an important role in the experience of chronic pain. This study examined the effects of a CBT treatment containing interoceptive exposure and relaxation for patients with chronic pain. The study used a single-subject design where six patients underwent a six week long individual treatment. The variables the study examined were changes concerning degree of acceptance, pain intensity, changes concerning pain related anxiety, kinesiophobia, catastrophizing and function. Participation in the treatment was associated with increased acceptance, improved function, reduced pain intensity, reduced pain related anxiety, less catastrophizing and reduced kinesiophobia. The study indicates that this treatment can lead to positive changes with pain patients in both cognitive and emotional components as well as behavioral components.

    Effects of the road environment on the development of driver sleepiness in young male drivers2018In: Accident Analysis and Prevention, ISSN 0001-4575, E-ISSN 1879-2057, Vol. 112, p. 127-134Article in journal (Refereed)
    Abstract [en]

    Latent driver sleepiness may in some cases be masked by for example social interaction, stress and physical activity. This short-term modulation of sleepiness may also result from environmental factors, such as when driving in stimulating environments. The aim of this study is to compare two road environments and investigate how they affect driver sleepiness. Thirty young male drivers participated in a driving simulator experiment where they drove two scenarios: a rural environment with winding roads and low traffic density, and a suburban road with higher traffic density and a more built-up roadside environment. The driving task was essentially the same in both scenarios, i.e. to stay on the road, without much interaction with other road users. A 2 x 2 design, with the conditions rural versus suburban, and daytime (full sleep) versus night-time (sleep deprived), was used. The results show that there were only minor effects of the road environment on subjective and physiological indicators of sleepiness. In contrast, there was an increase in subjective sleepiness, longer blink durations and increased EEG alpha content, both due to time on task and to night-time driving. The two road environments differed both in terms of the demand on driver action and of visual load, and the results indicate that action demand is the more important of the two factors. The notion that driver fatigue should be countered in a more stimulating visual environment such as in the city is thus more likely due to increased task demand rather than to a richer visual scenery. This should be investigated in further studies.

    The effect of daylight versus darkness on driver sleepiness: A driving simulator study2017In: Journal of Sleep Research, ISSN 0962-1105, E-ISSN 1365-2869Article in journal (Refereed)
    Abstract [en]

    Driver sleepiness studies are often carried out with alert drivers during daytime and sleep-deprived drivers during night-time. This design results in a mixture of different factors (e.g. circadian effects, homeostatic effects, light conditions) that may confound the results. The aim of this study was to investigate the effect of light conditions on driver sleepiness. Thirty young male drivers (23.6 ± 1.7 years old) participated in a driving simulator experiment where they drove on a rural road. A 2 × 2 design was used with the conditions daylight versus darkness, and daytime (full sleep) versus night-time (sleep deprived). The results show that light condition had an independent effect on the sleepiness variables. The subjective sleepiness measured by Karolinska Sleepiness Scale was higher, lateral position more left-oriented, speed lower, electroencephalogram alpha and theta higher, and blink durations were longer during darkness. The number of line crossings did not change significantly with light condition. The day/night condition had profound effects on most sleepiness indicators while controlling for light condition. The number of line crossings was higher during night driving, Karolinska Sleepiness Scale was higher, blink durations were longer and speed was lower. There were no significant interactions, indicating that light conditions have an additive effect on sleepiness. In conclusion, Karolinska Sleepiness Scale and blink durations increase primarily with sleep deprivation, but also as an effect of darkness. Line crossings are mainly driven by the need for sleep and the reduced alertness at the circadian nadir. Lane position is, however, more determined by light conditions than by sleepiness.

    Video-based observer rated sleepiness versus self-reported subjective sleepiness in real road driving2015In: European Transport Research Review, ISSN 1867-0717, E-ISSN 1866-8887, Vol. 7, no 4, article id 38Article in journal (Refereed)
    Abstract [en]

    Purpose: Observer-rated sleepiness (ORS) based on video recordings of the driver's face is often used when analysing naturalistic driving data. The aim of this study is to investigate if ORS ratings agree with subjective self-reported sleepiness (SRS). Methods: Forty raters assessed 54 video-clips showing drivers with varying levels of sleepiness. The video-clips were recorded during a field experiment focusing on driver sleepiness using the same cameras that are typically used in large-scale field studies. The weak results prompted a second test. Ten human factors researchers made pairwise comparisons of videos showing the same four participants in an alert versus a very sleepy condition. The task was simply to select the video-clip where the driver was sleepy. Results: The overall average percentage of video segments where ORS and SRS matched was 41 % in Test 1. ORS 0 (alert) and ORS 2 (very sleepy) were easier to score than ORS 1 and it was slightly harder to rate night-time drives. Inter-rater agreement was low, with average Pearson's r correlations of 0.19 and Krippendorff's alpha of 0.15. In Test 2, the average Pearson's r correlations was 0.35 and Krippendorff's alpha was 0.62. The correspondence between ORS and SRS showed an agreement of 35 %. Conclusions: The results indicate that ORS ratings based on real road video recordings correspond poorly with SRS and have low inter-rater agreement. Further research is necessary in order to further evaluate the usefulness of ORS as a measure of sleepiness.

    Dangerous use of mobile phones and other communication devices while driving: A toolbox of counter-measures2013In: Proceedings of the 16th International Conference Road Safety on Four Continents: Beijing, China. 15-17 May 2013, Linköping: Statens väg- och transportforskningsinstitut, 2013Conference paper (Other academic)
    Abstract [en]

    The use of mobile phone and similar devices while driving has been a topic of discussion and research for several years. It is now an established fact that driving performance is deteriorated due to distraction but no clear conclusions can yet be drawn concerning influence on crash rates. Better studies on this relationship is needed. Most countries in Europe and many countries elsewhere have introduced different types of bans for handheld devices. Sweden has, however, no such bans. VTI was commissioned by the Swedish Government to outline possible means to reduce the dangerous usage of mobile phones and other communication devices while driving as alternatives to banning. This task was a result of a previous VTI-state-of-the-art review of research on mobile phone and other communication device usage while driving. One of the findings in the review was that bans on handheld phones did not appear to reduce the number of crashes.

    Eighteen different countermeasures in three main areas were suggested. (1) Technical solutions such as countermeasures directed towards the infrastructure, the vehicle and the communication device. (2) Education and information, describing different ways to increase knowledge and understanding among stakeholders and different driver categories. (3) Different possibilities for how society, industry and organisations can influence the behaviour of individuals, via policies, rules, recommendations and incentives. Our conclusion is that a combination of different countermeasures is needed – where education and information to the drivers are combined with support and incentives for a safe usage of different communication devices.

    Förares användning av kommunikationsutrustning under färd: Del 1: Enkätstudie. Del 2: Användning enligt objektiv mätning2017Report (Other academic)
    Abstract [sv]

    Av resultaten från denna enkät är något av det mest tydliga att saker som funnits i en bil en längre tid, exempelvis att ställa in radio, använda navigationsutrustning och prata i telefon, görs i betydligt högre utsträckning än nyare saker som att skicka meddelanden, surfa på internet eller spela spel. Överlag tycks det vara låg acceptans för de nyare företeelserna och en stor andel av urvalet tycker att det är felaktigt eller olämpligt att hålla på med dessa aktiviteter. Att prata i telefon med handsfree tycks uppfattas av många som säkrare och mer lämpligt än att inte använda det. Detta avspeglas även i inställning till införandet av förbud, där en relativt stor andel accepterar att det ska vara lagligt att använda handsfreefunktioner men att annan användning av kommunikationsutrustning borde förbjudas.

    I den andra delen genomfördes en mätning av mobilanvändning under färd genom installerande tav en mobilapp. Den genomförda undersökningen är den första av sitt slag åtminstone i Sverige, så att den, trots vissa brister och begränsningar, kan leverera information som hittills har varit okänt. I detta del diskuteras resultaten, även i förhållande till enkätsvaren, följt av en reflektion över metoden och möjliga förbättringar, som är önskvärda inför en fortsättningsstudie.

    Local changes in the wake electroencephalogram precedes lane departures2017In: Journal of Sleep Research, ISSN 0962-1105, E-ISSN 1365-2869Article in journal (Refereed)
    Abstract [en]

    The objective of this exploratory study is to investigate if lane departures are associated with local sleep, measured via source-localized electroencephalography (EEG) theta power in the 5-9 Hz frequency range. Thirty participants drove in an advanced driving simulator, resulting in 135 lane departures at high levels of self-reported sleepiness. These lane departures were compared to matching non-departures at the same sleepiness level within the same individual. There was no correspondence between lane departures and global theta activity. However, at the local level an increased risk for lane departures was associated with increased theta content in brain regions related to motor function.

    Changes in glance behaviour when using a visual eco-driving system: A field study2017In: Applied Ergonomics, ISSN 0003-6870, E-ISSN 1872-9126, Vol. 58, p. 414-423Article in journal (Refereed)
    Abstract [en]

    While in-vehicle eco-driving support systems have the potential to reduce greenhouse gas emissions and save fuel, they may also distract drivers, especially if the system makes use of a visual interface. The objective of this study is to investigate the visual behaviour of drivers interacting with such a system, implemented on a five-inch screen mounted above the middle console. Ten drivers participated in a real-world, on-road driving study where they drove a route nine times (2 pre-baseline drives, 5 treatment drives, 2 post-baseline drives). The route was 96 km long and consisted of rural roads, urban roads and a dual-lane motorway.

    The results show that drivers look at the system for 5–8% of the time, depending on road type, with a glance duration of about 0.6 s, and with 0.05% long glances (>2s) per kilometre. These figures are comparable to what was found for glances to the speedometer in this study. Glance behaviour away from the windscreen is slightly increased in treatment as compared to pre- and post-baseline, mirror glances decreased in treatment and post-baseline compared to pre-baseline, and speedometer glances increased compared to pre-baseline. The eco-driving support system provided continuous information interspersed with additional advice pop-ups (announced by a beep) and feedback pop-ups (no auditory cue). About 20% of sound initiated advice pop-ups were disregarded, and the remaining cases were usually looked at within the first two seconds. About 40% of the feedback pop-ups were disregarded. The amount of glances to the system immediately before the onset of a pop-up was clearly higher for feedback than for advice.

    A gaze-based driver distraction warning system and its effect on visual behaviour2013In: IEEE transactions on intelligent transportation systems (Print), ISSN 1524-9050, E-ISSN 1558-0016, Vol. 14, no 2, p. 965-973Article in journal (Refereed)
    Abstract [en]

    Driver distraction is a contributing factor to many crashes; therefore, a real-time distraction warning system should have the potential to mitigate or circumvent many of these crashes. The objective of this paper is to investigate the usefulness of a real-time distraction detection algorithm called AttenD. The evaluation is based on data from an extended field study comprising seven drivers who drove on an average of 4351 ± 2181 km in a naturalistic setting.

    Visual behavior was investigated both on a global scale and on a local scale in the surroundings of each warning. An increase in the percentage of glances at the rear-view mirror and a decrease in the amount of glances at the center console were found. The results also show that visual time sharing decreased in duration from 9.94 to 9.20 s due to the warnings, that the time from fully attentive to warning decreased from 3.20 to 3.03 s, and that the time from warning to full attentiveness decreased from 6.02 to 5.46 s. The limited number of participants does not allow any generalizable conclusions, but a trend toward improved visual behavior could be observed. This is a promising start for further improvements of the algorithm and the warning strategy.

    Using smartphone logging to gain insight about phone use in traffic2019In: Cognition, Technology & Work, ISSN 1435-5558, E-ISSN 1435-5566Article in journal (Refereed)
    Abstract [en]

    The prevalence of mobile phone usage in traffic has been studied by road-side counting, naturalistic driving data, surveillance cameras, smartphone logging, and subjective estimates via surveys. Here, we describe a custom-made smartphone logging application along with suggestions on how future such applications should be designed. The developed application logs’ start and end times of all phone interactions (mobile phone applications, incoming/outgoing phone calls and text messages, audio output, and screen activations). In addition, all movements are automatically classified into transport, cycling, walking, running, or stationary. The capabilities of the approach are demonstrated in a pilot study with 143 participants. Examples of results that can be gained from smartphone logging include prevalence in different transportation modes (here found to be 12% while driving, 4% while cycling, and 7% while walking), which apps are being used (here found to be 19% navigation, 12% talking, 12% social media, and 10% games) and on which road types (rural, urban, highway etc.). Smartphone logging was found to be an insightful complement to the other methods for assessing phone use in traffic, especially since it allows the analyses of which apps are used and where they are used, split into transportation mode and road type, all at a relatively low cost.

    Gymnasieelevers syn på feedback i skolämnet idrott & hälsa2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of the study was to examine how high school students wish to receive feedback in physical education, if positive feedback from the P.E. teacher is perceived as beneficial to the students’ motivation and also to examine if the motivational climate is perceived as task oriented or ego oriented by the students. In total 8 high school students (4 boys, 4 girls) at the age of 16 participated. Semi structured interview guides were used during the interviews who took place in a private and neutral location. The informants wanted positive feedback and instructive feedback. Positive feedback was perceived as beneficial to the informants’ motivation. They also perceived encouragement as beneficial to their motivation. Both task oriented and ego oriented motivational climate were experienced. However the P.E. teacher was perceived as using a task oriented approach. The informants’ answers related to both Self determination theory (Deci & Ryan, 2000) and Achievement goal theory (Nicholls, 1989). According to the study, the P.E. teacher’s feedback approach should concentrate on positive, encouraging, instructing and constructive feedback and have a task oriented approach.

    Hörselskadade barn i kommunikation och samspel2000Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The aim of this thesis was to study the communicative and social development of twelve hard of hearing children, between the ages of two and seven. The children were observed by videorecordings, during a two year period in natural settings in three different sign language preschools, where sign language and spoken Swedish was exposed to the children at a varying extent. The theoretical basis of this thesis is found in modem child development research emphasising the significance of early close relationships with adults and peers. In order to give a description of the cultural context, interviews were made with parents and staffmembers. A descriptive qualitative analysis of the non-verbal and verbal communication between the children and the staff-members was conducted in order to focus on patterns of interaction within the group of hard of hearing children and between hard of hearing and deaf children, as well as between the children and the staff-members. From the analysis, five different patterns of interaction emerged and will be presented as five case studies at an individual and at a group level. These two perspectives were necessary in order to understand the way the hard of hearing children communicated in different contexts. The adults attitudes towards play and language, manifested by the way in which they acted towards the children played a central part to the outcome of peer-peer and adult-child interactions. The research findings indicated that a multitude of circumstances influenced the development of communicative skills of the children. The use of a language that enabled them to understand and to be understood, a supportive communicative style of the adults, where focus was on the content and the quality of the interaction in combination with a positive attitude towards fantasy and role play seemed to promote the children’s well-being and communicative and social development, more than an adult-centred and directive communicative style where the two languages per se were in focus.

    Anställningsformer och upplevd stress: Påverkar individers anställningsvillkor deras upplevda stressnivå?2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie var att undersöka om det finns ett samband mellan upplevd stress och anställningsform. Studien presenterade tre hypoteser: 1) Individer med fast anställning upplever mindre stress än individer med andra anställningsformer, 2) Anställningsform/anställningsvillkor påverkar upplevd stress i skalan PSS-14, 3) Kön, ålder, utbildning, arbetstid och familjesituation påverkar upplevd stress av arbetsförhållanden enligt stressskalan PSS-14. Studien genomfördes med hjälp av en kvantitativt enkätundersökning som distributerades online med stresskalan PSS-14 som underlag. Totalt besvarade 157 personer enkäten om stress och arbete, 122 deltagare angav att de var kvinnor och 34 män. T-test för oberoende variabler genomfördes. T-testen visade att det inte fanns signifikanta skillnader mellan anställningsform, ålders, civilstånd, kön eller arbetstid.

    VILKEN ORGANISATION IDENTIFIERAR SIG KONSULTER MED?2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Att anlita konsulter i stället för att anställa egen personal blir allt vanligare på arbetsmarknaden i Sverige. Syftet med föreliggande studie var att få inblick i vilken organisation konsulter identifierar sig med – konsultbolaget eller uppdragsgivaren. Åtta konsulter på ett konsultbolag inriktat mot offentlig sektor, i Sverige, intervjuades. Intervjuerna berörde både konsultbolagets befintliga upplägg för att öka identifikationen med bolaget samt möjliga sätt att öka denna. Även relationen mellan konsulten och uppdragsgivaren, ur konsultens synvinkel, berördes. I resultatet framkom en bild av att vid långa uppdrag på heltid så identifierar sig konsulterna generellt mer med uppdrags-givaren än med konsultbolaget. Att schemalägga en veckodag då konsulten ska vara på plats på konsultbolagets kontor framträdde som ett möjligt sätt att öka identifikationen med konsultbolaget vid långa heltidsuppdrag.

    Livet är ditt!: en studie om livskvalitet och motiverande samtal2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte och frågeställningar

    Syftet med studien var att undersöka om en kortare period av motiverande samtal (MI) kunde påverka livskvaliteten positivt hos en arbetande population. De tre frågeställningarna var: Kan en kort period av MI förändra livskvaliteten positivt? Vilka eventuella effekter har en kortare period av MI på livskvaliteten? Finns det några skillnader i eventuell förändring av livskvalitet mellan kön, ålder samt utbildningsnivå?

    Metod

    Studien bestod av två MI-samtal med tre veckors mellanrum, samt en enkätundersökning som genomfördes före och efter samtalsperioden. Ett företag kontaktades och deltagarna rekryterades genom information på företagets intranät. 25 anmälda bildade MI-gruppen och därefter efterfrågades kontrollgruppsdeltagare via mail, 23 anställda bildade kontrollgruppen. Företaget hade sedan många år tillbaka haft ett nära samarbete med företagshälsovården. En redan framtagen livskvalitetsenkät, SF-36, användes tillsammans med en egen kompletterande enkät om kön, ålder och utbildning. Enkätsvaren kodades om och analyserades enligt manualen för SF-36. Därefter utfördes statistiska tester för att få fram eventuella skillnader inom och mellan grupperna. Det totala bortfallet blev fyra personer från kontrollgruppen, resultatet beräknades utifrån 19 deltagare i kontrollgruppen och 25 deltagare från MI-gruppen.

    Resultat

    Resultaten visade att en kortare period av MI inte kunde förändra livskvaliteten och att det inte heller fanns någon signifikant skillnad i livskvalitet mellan grupperna. Vi tror att det bland annat kan bero på det tidigare hälsoarbetet på företaget. Däremot kunde en signifikant förbättring av den mentala hälsan inom MI-gruppen konstateras som en effekt. Det fanns inga skillnader i förändring av livskvalitet mellan kön, ålder och utbildningsnivå.

    Slutsats

    Slutsatsen blev att signifikanta resultat på livskvaliteten inte går att uppnå på så kort tidsperiod som studien avsåg. Utifrån de givna tidsramarna var studiens modell hanterbar och kunde ändå uppvisa resultat i form av en förbättring av mental hälsa hos MI-gruppen.

    Understanding Individuals' Learning and Decision Processes in a Changing Environment by Using Panel Data2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    When a new transport service is introduced, people have to learn and familiarize themselves with the new service before they decide to adopt it. These processes are developed over time, thus produce dynamics in individuals’ behavioural responses towards the service. This affects the demand of the new service, thus affect revenues. Available studies have examined the factors influencing these responses from microeconomic perspectives. The influence of the theory-based subjective factors has not been examined empirically. Understanding these would assist transport and urban planners to design a better marketing strategy to increase the market share of the new service. A change in seasons affect individuals’ activity-travel decisions, thus produce dynamics in activitytravel patterns in different seasons. Individuals’ constraints, in a form of mandatory activities (working/studying), are influencing individuals’ decisions to participate in day-to-day nonmandatory activities (leisure and routine activities). The interdependency between travel demand, time allocation and mode choice that considers interactions between mandatory and non-mandatory activities, in different seasons is less explored. Understanding these would assist transport planners and operators to manage travel demand strategies across different seasons of the year and provide better transportation systems for all individuals. This thesis includes five papers. Paper I explores individuals’ characteristics of the quick-response and the adopters of the new public transport (PT) service and examines the temporal effects. Paper II investigates the subjective factors influencing a quick-response to the new PT service by proposing a modified attitude-behaviour framework. Paper III and IV analyse the effects of seasonal variations and individuals’ constraints on their day-to-day activity-travel decisions and patterns. Paper V analyses the attrition and fatigue in the two-week travel diary panel survey instrument.

    Subjective Factors Influencing Individual's Response to a New Public Transport ServiceManuscript (preprint) (Other academic)
    Abstract [en]

    The timing and nature of people’s responses can be expected to vary when a new element enter their environment. For example, when an individual is provided with a new or modified transport service. This time-scale of behavioural responses will affect the patronage of, and short- and long-term demands on the new service over time. Understanding the underlying factors that influence an individual’s response over time to a new or modified transport service would enable us to identify trigger factors that make the new service attractive from an individual’s point of view. Chatterjee (2001) and Douglas (2003) argued that motives other than instrumental factors related to public transport use, such as attitudes, awareness, travel habits and learning processes, can influence individual responses over time to changes in the travel environment. Unfortunately, despite their importance, there have been few studies that examined this argument empirically. To address this research gap, this paper aims to investigate the influences of subjective factors on individuals’ responses to the introduction of a modified public transport (PT) service over time by proposing and testing an alternative model that modifies the theory of planned behaviour (TPB) model framework. This paper also aims to investigate the behavioural change in terms of attitudes and perceptions on individuals’ resources and constraints in using a modified PT service over time after its introduction. The case study involves the new extension of a tram line connecting the suburbs of Alvik and Solna Centrum in Stockholm, Sweden. Four waves of a panel survey were conducted with 96 individuals who lived along the new service, from just before the new service was introduced and until seven months after its introduction. A structural equation modelling technique was used to estimate the relationships between behavioural constructs and panel data, then incorporate them into a discrete choice model. The results show that intention influences individual’s quick-response choice. The panel analysis shows that past behaviour in using the new service influenced current behaviour, and that perceived walking distance in using the service consistently influenced the frequency of using the new service over time.

    Abstract [en]

    Information technology is playing a vital role in our every field of life. The most common use of information is in the field of education. Use of information technology in libraries is very important. People from differents works of life extract information from these libraries. In this paper, we have tried to identify how can we facilitate the Umeå university library users for better interaction with the information? We have used different methods for collection of data to identify the Umeå university libray problems and then we analysed the whole library system with the help of Engeström Activity theory, to find out which factors are effeting the interaction between users and library and creating main problems. In the end we have given some suggestions for the improvement of interaction between users and Umeå library to facilitate them for accessing information.

    Religion, culture and illness: a sociological study on religious coping in Iran2018In: Mental Health, Religion & Culture, ISSN 1367-4676, E-ISSN 1469-9737, Vol. 21, no 7, p. 721-736Article in journal (Refereed)
    Abstract [en]

    The present article is based on an international study on meaning-making coping aimed at understanding the role of culture in coping. The larger study has been conducted among cancer patients in 10 countries. The present article is confined to the results obtained in our study in Iran and restricted to religious coping methods. Twenty-seven participants with various kinds of cancer were interviewed. The several religious coping methods found in the present study are categorised on the basis of RCOPE?s five basic religious functions. The study reveals, among others, the impact of cultural beliefs on certain religious coping methods, even among those who are not regarded as practicing Muslims. The study highlights the importance of investigating cultural and social context when exploring the use of the meaning-making coping strategies in different countries.

    Muslim discrimination: evidence from two lost letter experiments2010In: Journal of Applied Social Psychology, ISSN 0021-9029, E-ISSN 1559-1816, Vol. 40, no 4, p. 888-898Article in journal (Refereed)
    Abstract [en]

    Since the 9/11 terrorist attacks, there has been considerable concern about whether Muslims living in Western countries are targets of prejudice. A considerable amount of survey-based evidence suggests that Muslims are victims of discrimination. This paper tested this hypothesis. Two lost-letter experiments were conducted to test whether the difference in returned letters would be attributable to whether the addressee was Muslim or Swedish. The results show that Muslims receive far fewer letters than do Swedes. However, this discrimination only appears when the lost letters contain money; in which case, the finder gains by not posting the letter.

    Perceptions of gay, lesbian, and heterosexual domestic violence among undergraduates in Sweden2013In: International Journal of Conflict and Violence, ISSN 1864-1385, E-ISSN 1864-1385, Vol. 7, no 2, p. 249-260Article in journal (Refereed)
    Abstract [en]

    An experimental study of perceptions about gay, lesbian, and heterosexual domestic violence in Sweden. Undergraduate students (N = 1009) read one of eight fictitious scenarios of domestic violence in married couple relationships, where sexual orientation, sex of victim and batterer, and severity of violence were varied. Perceptions of seriousness of the described incident and attitudes toward women, gays and lesbians were measured. Domestic violence was perceived as more serious in cases where: the respondent was a woman, the batterer was a man, the victim was a woman, or the battering was severe. Wife-battering in a heterosexual relationship was considered the most serious case in both the less and more severe battering scenario. Where battering was less severe, domestic violence in gay and lesbian relationships was perceived as more serious than heterosexual husband-battering; this difference disappeared in the severe battering scenario. Negative attitudes toward gays, lesbians, and women were associated with less concern about domestic violence in all types of relationships. The findings suggest that stereotypes about gays, lesbians, and women affect perceptions of domestic violence, but mainly when violence is less severe.

    Personliga assistenters upplevelse av deras psykologiska kontrakt2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Abstract

    The purpose of the study was to examine how personal assistants experience their psychological contract and how the psychological contract was fulfilled against their supervisor or manager.A qualitative method was used and seven interviews were conducted with personal care assistants from various workplaces. The interviews were analysed with thematic analysis and resulted in five main themes. Expectations, personal but not private, what really stands in the contract, how people look at the profession and fulfilment. In conclusion, the main result was that the personal care assistants experienced that the internal psychological contract consisted of the relation to the supervisor or manager and the accessibility to the employer. The personal care assistants felt that the contents of the external psychological contract consisted of the work duties, employment security, working hours and the attractiveness of the profession. The majority of the respondents felt that the internal and external psychological contract was fulfilled. None of the respondents considered that the internal and external psychological contract was not fulfilled at all.

    Radikala och extrema grupper: Anslutning, kontinuitet och urkoppling i ljuset av social identitetsteori2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Studier om engagemang i extrema och radikala grupper har begränsats till en grupp åt gången. Djupare psykologisk förståelse för fenomenet har efterfrågats. Syftet med föreliggande studie var att utforska likheter mellan föredetta medlemmar av olika radikala och extrema grupper, beträffande faktorer bidragande till anslutning, kontinuitet och urkoppling, samt hur processen bakom anslutning, kontinuitet och urkoppling kan förklaras med hjälp av social identitetsteori (Tajfel & Turner, 1986). Intervjumaterialet (N=7) analyserades med en blandning av induktiv och deduktiv tematisk analys. Anslutning associeras med utanförskap, dysfunktionella familjeförhållanden, emotionell belastning och manipulation. Kontinuitet associeras med familjeliknande förhållanden, betydelsefulla roller, ökad självsäkerhet, tydliga mål och aspiration, ökade aktiviteter, polariserade föreställningar och motsättningar. Urkoppling associeras med personlig utveckling, distans och psykisk ohälsa. Ett förslag till förklaringsmodell presenteras. Negativ social identitet leder till anslutning, positiv social identitet leder till kontinuitet, hotad social identitet kan leda till eller ifrån kontinuitet, negativ social identiet leder till urkoppling.

    How reliable are eyewitness memories? Effects of retention interval, violence of act, and gender stereotypes on observers' judgments of their own memory regarding witnessed act and perpetrator:  2012In: Psychology, Crime and Law, ISSN 1068-316X, E-ISSN 1477-2744, Vol. 18, no 5, p. 491-503Article in journal (Refereed)
    Abstract [en]

    An experiment was conducted to evaluate the effects of (i) stimulus person's gender, (ii) type of act (neutral or violent), and (iii) retention interval (short or long) on observers' memory of a stimulus person. Participants were presented with one of two acts: neutral (walking around in a store) or violent (robbing a store). The retention interval was 10 minutes or one-three weeks. The dependent variables were questionnaire items concerning the participants' memory of (1) the stimulus person's appearance and (2) the event, and (3) rating scales where the participants were asked to evaluate the stimulus person's aggressiveness, insensitivity, and other personality traits as well as characteristics of the act. Results showed that when the act was violent, and a long retention interval was used, a female, but not a male, stimulus person was evaluated less harshly than with a short retention interval (enhancement of gender stereotype); a stimulus person was seen as behaving in a more masculine way when performing a violent rather than a neutral act; witnessing the violent act resulted in better self-rated memory of the stimulus person; and with increasing retention interval, the violent act was seen as less negative and the neutral act as more negative (regression toward the mean).

    Justice needs a blindfold: Effects of defendants’ gender and attractiveness on judicial evaluation2010Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Gender and appearance affect our judgments regarding an individual’s personality, profession, and morality, and create a reference frame within which to act toward that person. The main question of the present thesis is whether these kinds of stereotypical conceptions have implications for the judicial process: how professionals within the judicial process evaluate and judge a defendant, and how and what eyewitnesses remember. Expressed in other words: Is justice blind or do gender and appearances affect the treatment we receive in a judicial process?

    The main purpose of the present thesis was to study the effects of gender and attractiveness on evaluations of defendants accused of crimes of varying seriousness and type. The second theme was to study under what circumstances these effects are particularly strong; emotionality, retention interval, as well as gender and profession of evaluators, were controlled for.

    Study 1 aimed at investigating “pure” gender and attractiveness effects, with psychology students as participants. Study II added the variable of emotionality, as well as six groups of evaluators. Emotionality was studied by including emotional photographs of crime victim injury as well as two levels of vividness in the written description the evaluator was to read. The evaluators were professionals working within the judicial process in Sweden–judges, jury members, counsels for the defence, prosecutors, and police officers–as well as law students. Study 1 showed that a male defendant was evaluated more negatively than a female. Study II showed two main tendencies: (i) “same-sex penalty effect”: Sentencing evaluators (judges, jurors) evaluated a defendant of their own gender more harshly than one of the opposite gender; (ii) “male penalty effect”: Nonsentencing evaluators (police officers, counsels for the defence, prosecutors, and law students) evaluated and judged a male defendant more harshly than a female. Study III focused on exploring effects of violence (emotionality) and retention interval in the context of gender differences to investigate under which circumstances gender differences might be especially strengthened. Violence was manipulated using two acts: one neutral (walking in a store) and one violent (robbing the same store). Retention interval was of two lengths: 10 minutes and 1-3 weeks. Results revealed a gender-stereotype-enhancement effect, in which the evaluator evaluated the male defendant more harshly with the longer retention interval as well as in the violent act condition. The results of the present studies may have practical implications for the functioning of the judicial process; on the eyewitness hearing level (Study III) as well as on the evidence evaluation-, guilt-, and punishment assessment levels (Studies I and II).

    Justice Needs a Blindfold: Effects of Gender and Attractiveness on Prison Sentences and Attributions of Personal Characteristics in a Judicial Process2009In: Psychiatry, Psychology and Law, ISSN 1321-8719, E-ISSN 1934-1687, Vol. 16, no 1, p. 90-100Article in journal (Refereed)
    Abstract [en]

    This study examined the effect of gender and facial characteristics of criminal offenders on attributions of crime-relevant traits. The stimulus pictures portrayed women and men of varying attractiveness. Participants were presented with pictures of these female or male faces along with accompanying crime accounts. The crime account described the individual in the picture as a person who had committed one of the following crimes: theft, fraud, drug crime, child molestation, child abuse, or homicide. After reading one case account the participants were asked to evaluate the credibility and other crime-relevant personality traits of the offender. Results showed that female defendants were rated more favourably than were male defendants. Gender worked to the advantage of the female perpetrator. There were also slight tendencies towards more lenient appraisal of the more attractive women.

    Is Justice Really Blind?: Effects of Crime Descriptions, Defendant Gender and Appearance, and Legal Practitioner Gender on Sentences and Defendant Evaluations in a Mock Trial2010In: Psychiatry, Psychology and Law, ISSN 1321-8719, E-ISSN 1934-1687, Vol. 17, no 2, p. 304-324Article in journal (Refereed)
    Abstract [en]

    Two experiments were conducted to investigate how sources of information can bias the judicial process. Experiment 1 investigated the effects of photographs of victims’ injury, and of vivid verbal victim injury description, on the evaluation and sentencing of a defendant in a mock criminal trial. The participants were presented with five different crime accounts: (a) vandalism, (b) arson, (c) child abuse, (d) child molestation, and (e) homicide, all committed by male perpetrators, and were asked to evaluate the trustworthiness, culpability, aggressiveness, guilt, and other crime-relevant personality traits of the defendant, and to set imprisonment sentences. Results of Experiment 1 showed that exposure to photographs of crime victim injuries as well as vivid crime descriptions had only weak and non-significant effects on defendant evaluations, but imprisonment terms tended to be longer in the Photo condition than in the No photo condition. To further investigate the possible effects of photographic information on judicial processes for different crimes (child molestation, child abuse, homicide), Experiment 2 was conducted with legal practitioners (judges, members of Swedish juries, law students, counsels for the defence, prosecutors, police officers) as evaluators. Results showed three tendencies: (a) a ‘‘same-sex penalty effect’’: sentencing evaluators (judges, jurors) evaluated a defendant of the same gender as the evaluator, more harshly than one of the opposite gender, (b) a ‘‘male penalty effect’’: non-sentencing evaluators (police officers, counsels for the defence, prosecutors, and law students) evaluated and judged a male defendant more harshly than a female, and (c) for female non-sentencing evaluators, the male penalty effect was enhanced for the more attractive defendants. Overall, the results suggest that defendant gender, defendant appearance, evaluator gender, and evaluator profession can affect the outcome of a criminal trial.

    In presence of risk, what protective factors keep preschool children from displaying conduct problems?2008Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [en]

    Children that are expressing or are exposed to risk factors experience an elevated risk of developing later psychosocial maladjustment, such as conduct problems. However, all children exposed to risk do not express conduct problems, but develop normally. The aim of the present study was to examine potential protective factors among children exposed to risk, that separate children expressing conduct problem behavior from those who do not. In the study, preschool teachers and parents of 298 three- to five-year-old children participated. Risk factors of the individual, conduct problem behavior, and relationship oriented protective factors were examined. The results indicate that positive peer relationships are important for preschool children´s psychosocial development, while family factors, such as parent's disciplinary style, seem less important.

    Abstrakt eller konkret verklighet?: Om hur psykologisk distans inverkar på perception2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Förståelsen för andra människor som krävs för lyckade interaktioner, förklaras i attributionsteorierna "Theory of Mind" och "Simulation Theory. Ett vanligt men ouppklarat fenomen är det fundamentala attributionsfelet, där beteende felaktigt attribueras till inre generella egenskaper. Fenomenet reflekterar en abstrakt mental konstruktion i enlighet med Construal Level Theorys antagande om hur psykologisk distans inverkar på perception. I en modifierad Attitude Attribution Paradigm modell undersöks om spatial distans påverkar det fundamentala attributionsfelet och om skillnader föreligger mellan kvinnor och män. Kort/lång spatial distans primades genom en kontroversiell text, via information om dess kompositionsplats, som fungerade som underlag för bedömning av skribentens åsikt. En variansanalys visade ingen signifikant effekt av spatial distans, inte heller någon skillnad mellan kvinnor och män. Resultaten kan ha påverkats av den modifierade undersökningsmodellen, vilken kan ha medlat en implicit antydan om en uttryckt åsikt.

    Psychosocial determinants and family background in anorexia nervosa: Results from the Stockholm Birth Cohort Study2012In: International Journal of Eating Disorders, ISSN 0276-3478, E-ISSN 1098-108X, Vol. 45, no 3, p. 362-369Article in journal (Refereed)
    Abstract [en]

    Objective: The aim of this study was to examine the associations between psychosocial factors and family background and incidence of anorexia nervosa (AN) in a Swedish cohort.

    Method: The Stockholm Birth Cohort, SBC (N = 14,294) contains information on social background and general health in males and females, born in Stockholm 1953. Hospitalizations for AN, based on diagnoses from the ICD-8 through ICD-10, were recorded from 1969 to 2002. Cox proportional hazard regression was used to measure the association between psychosocial characteristics and family background and the risk of AN.

    Results: Higher maternal education was associated with a higher risk for hospitalization for AN. An increased risk for AN was also found among females who stated that they “often compare their future prospects with others.”

    Discussion: Although the study is based on a low number of cases, it confirms earlier findings of higher maternal education among individuals with eating disorders in similar cohorts.

    We are family - parents, siblings, and eating disorders in a prospective total-population study of 250,000 Swedish males and females2013In: International Journal of Eating Disorders, ISSN 0276-3478, E-ISSN 1098-108X, Vol. 46, no 7, p. 693-700Article in journal (Refereed)
    Abstract [en]

    Objective: We examined how parental characteristics and other aspects of family background were associated with the development of eating disorders (ED) in males and females.

    Method: We used register data and record linkage to create the prospective, total-population study the Stockholm Youth Cohort. This cohort comprises all children and adolescents who were ever residents in Stockholm County between 2001 and 2007, plus their parents and siblings. Individuals born between 1984 and 1995 (N = 249, 884) were followed up for ED from age 12 to end of 2007. We used Cox regression modeling to investigate how ED incidence was associated with family socioeconomic position, parental age, and family composition.

    Results: In total, 3,251 cases of ED (2,971 females; 280 males) were recorded. Higher parental education independently predicted a higher rate of ED in females [e.g., adjusted hazard ratio (HR) 1.69 (95% CI: 1.42, 2.02) for degree-level vs. elementary-level maternal education], but not in males [HR 0.73 (95% CI: 0.42, 1.28), p < 0.001 for gender interaction]. In females, an increasing number of full-siblings was associated with lower rate of ED [e.g., fully adjusted HR 0.92 (95% CI: 0.88, 0.97) per sibling], whereas an increasing number of half-siblings was associated with a higher rate [HR 1.05 (95% CI: 1.01, 1.09) per sibling].

    Discussion: The effect of parental education on ED rate varies between males and females, whereas the effect of number of siblings varies according to whether they are full or half-siblings. A deeper understanding of these associations and their underlying mechanisms may provide etiological insights and inform the design of preventive interventions

    Personality traits and self-injury behaviour in patients with eating disorders2008In: European eating disorders review, ISSN 1072-4133, E-ISSN 1099-0968, Vol. 16, no 4, p. 268-275Article in journal (Refereed)
    Abstract [en]

    The interest in different aspects of personality and the neuropsychological basis for behaviour in eating disorder patients has increased over the last decade. The present study aims at exploring personality traits, self-injurious behaviour (SIB) and suicide attempts in a group of severely ill eating disorder patients. Patients with eating disorders (<i>N</i> = 38) and age-matched controls (N = 67) were examined concerning self-reported personality traits by means of the Karolinska scales of personality (KSP). Psychosocial history and SIB was collected from medical records. Depression was rated by means of the Beck Depression Inventory (BDI). Results indicated significantly higher anxiety-related and detachment traits in both anorexia nervosa (AN) and bulimia nervosa (BN) patients and higher hostility in BN patients than controls. No specific personality traits could be defined as typical for self-injurious or suicidal behaviour. The AN group was lower than the BN group on scales measuring impulsivity, guilt and anxiety. Furthermore, presence of SIB and suicide attempts was more frequent among the BN patients.

    Levels of tumour necrosis factor-alpha and interleukin-6 in severely ill patients with eating disorders2011In: Neuropsychobiology, ISSN 0302-282X, E-ISSN 1423-0224, Vol. 63, no 1, p. 8-14Article in journal (Refereed)
    Abstract [en]

    Background: The underlying pathophysiology of eating disorders (ED) is dependent on complex interactions between psychological, biological and social factors. The purpose of the present study was to examine a possible increase in cytokines indicating inflammation, as measured by tumour necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in ED patients, and to explore possible relationships between cytokines and self-reported personality traits. Methods: Female patients with severe ED (n = 26) were recruited consecutively from an inpatient clinic and were compared to age-matched healthy females (n = 12). Commercial ELISA tests developed for the measurement of serum levels of TNF-α and IL-6 were employed. Personality traits were measured using Karolinska Scales of Personality. Results: The patient group displayed increased levels of the cytokine TNF-α and a tendency towards increased IL-6 levels. Spearman's rank correlation coefficient was used to examine possible relationships between levels of cytokines and personality traits. The results showed that IL-6 levels were positively related to both somatic and psychic anxiety and to aggression scales, such as irritability and suspicion. Increased levels of TNF-α, in turn, were significantly correlated with high scores on the depression-related anxiety scale Inhibition of Aggression. However, increased levels of cytokines in the ED group did not seem to be mainly associated with symptoms of depression. Conclusion: We cannot rule out the possibility that comorbid conditions in the group contribute to the higher cytokine values. Further studies need to explore the possible influence of cytokines on the severity of ED and whether this might be mediated or moderated by specific personality traits.

    Association of Higher Parental and Grandparental Education and Higher School Grades With Risk of Hospitalization for Eating Disorders in Females: The Uppsala Birth Cohort Multigenerational Study2009In: American Journal of Epidemiology, ISSN 0002-9262, E-ISSN 1476-6256, Vol. 170, no 5, p. 566-575Article in journal (Refereed)
    Abstract [en]

    Eating disorders are a leading cause of disease burden amongyoung women. This study investigated associations of socialcharacteristics of parents and grandparents, sibling position,and school performance with incidence of eating disorders. Theauthors studied Swedish females born in 1952–1989 (n =13,376), third-generation descendants of a cohort born in Uppsalain 1915–1929. Data on grandparental and parental socialcharacteristics, sibling position, school grades, hospitalizations,emigrations, and deaths were obtained by register linkages.Associations with incidence of hospitalization for eating disorderswere studied with multivariable Cox regression, adjusted forage and study period. Overall incidence of hospitalization foreating disorders was 32.0/100,000 person-years. Women with morehighly educated parents and maternal grandparents were at higherrisk (hazard ratio for maternal grandmother with higher educationrelative to elementary education = 6.5, 95% confidence interval:2.2, 19.3, adjusted for parental education). Independent offamily social characteristics, women with the highest schoolgrades had a higher risk of eating disorders (hazard ratio =7.7, 95% confidence interval: 2.5, 24.1 for high compared withlow grades in Swedish, adjusted for parental education). Thus,higher parental and grandparental education and higher schoolgrades may increase risk of hospitalization for eating disordersin female offspring, possibly because of high internal and externaldemands.

    Women with Multiple Chemical Sensitivity Have Increased Harm Avoidance and Reduced 5-HT1A Receptor Binding Potential in the Anterior Cingulate and Amygdala2013In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203Article in journal (Refereed)
    Abstract [en]

    Multiple chemical sensitivity (MCS) is a common condition, characterized by somatic distress upon exposure to odors. As in other idiopathic environmental intolerances, the underlying mechanisms are unknown. Contrary to the expectations it was recently found that persons with MCS activate the odor-processing brain regions less than controls, while their activation of the anterior cingulate cortex (ACC) is increased. The present follow-up study was designed to test the hypotheses that MCS subjects have increased harm avoidance and deviations in the serotonin system, which could render them intolerant to environmental odors. Twelve MCS and 11 control subjects, age 22–44, all working or studying females, were included in a PET study where 5-HT1A receptor binding potential (BP) was assessed after bolus injection of [11C]WAY100635. Psychological profiles were assessed by the Temperament and Character Inventory and the Swedish universities Scales of Personality. All MCS and 12 control subjects were also tested for emotional startle modulation in an acoustic startle test. MCS subjects exhibited significantly increased harm avoidance, and anxiety compared to controls. They also had a reduced 5-HT1A receptor BP in amygdala (p = 0.029), ACC (p = 0.005) (planned comparisons, significance level 0.05), and insular cortex (p = 0.003; significance level p<0.005 with Bonferroni correction), and showed an inverse correlation between degree of anxiety and the BP in the amygdala (planned comparison). No group by emotional category difference was found in the startle test. Increased harm avoidance and the observed changes in the 5-HT1A receptor BP in the regions processing harm avoidance provides a plausible pathophysiological ground for the symptoms described in MCS, and yields valuable information for our general understanding of idiopathic environmental intolerances.

    Feature-based representations of emotional facial expressions in the human amygdala.2014In: Social cognitive and affective neuroscience, ISSN 1749-5024, Vol. 9, no 9, p. 1372-8Article in journal (Refereed)
    Abstract [en]

    The amygdala plays a central role in processing facial affect, responding to diverse expressions and features shared between expressions. Although speculation exists regarding the nature of relationships between expression- and feature-specific amygdala reactivity, this matter has not been fully explored. We used functional magnetic resonance imaging and principal component analysis (PCA) in a sample of 300 young adults, to investigate patterns related to expression- and feature-specific amygdala reactivity to faces displaying neutral, fearful, angry or surprised expressions. The PCA revealed a two-dimensional correlation structure that distinguished emotional categories. The first principal component separated neutral and surprised from fearful and angry expressions, whereas the second principal component separated neutral and angry from fearful and surprised expressions. This two-dimensional correlation structure of amygdala reactivity may represent specific feature-based cues conserved across discrete expressions. To delineate which feature-based cues characterized this pattern, face stimuli were averaged and then subtracted according to their principal component loadings. The first principal component corresponded to displacement of the eyebrows, whereas the second principal component corresponded to increased exposure of eye whites together with movement of the brow. Our results suggest a convergent representation of facial affect in the amygdala reflecting feature-based processing of discrete expressions.

    Mobile mental wellness training for stress management: feasibility and design implications based on a one-month field study.2013In: JMIR mHealth and uHealth, ISSN 2291-5222, Vol. 1, no 2, article id e11Article in journal (Refereed)
    Abstract [en]

    Prevention and management of work-related stress and related mental problems is a great challenge. Mobile applications are a promising way to integrate prevention strategies into the everyday lives of citizens.

    OBJECTIVE: The objectives of this study was to study the usage, acceptance, and usefulness of a mobile mental wellness training application among working-age individuals, and to derive preliminary design implications for mobile apps for stress management.

    METHODS: Oiva, a mobile app based on acceptance and commitment therapy (ACT), was designed to support active learning of skills related to mental wellness through brief ACT-based exercises in the daily life. A one-month field study with 15 working-age participants was organized to study the usage, acceptance, and usefulness of Oiva. The usage of Oiva was studied based on the usage log files of the application. Changes in wellness were measured by three validated questionnaires on stress, satisfaction with life (SWLS), and psychological flexibility (AAQ-II) at the beginning and at end of the study and by user experience questionnaires after one week's and one month's use. In-depth user experience interviews were conducted after one month's use to study the acceptance and user experiences of Oiva.

    RESULTS: Oiva was used actively throughout the study. The average number of usage sessions was 16.8 (SD 2.4) and the total usage time per participant was 3 hours 12 minutes (SD 99 minutes). Significant pre-post improvements were obtained in stress ratings (mean 3.1 SD 0.2 vs mean 2.5 SD 0.1, P=.003) and satisfaction with life scores (mean 23.1 SD 1.3 vs mean 25.9 SD 0.8, P=.02), but not in psychological flexibility. Oiva was perceived easy to use, acceptable, and useful by the participants. A randomized controlled trial is ongoing to evaluate the effectiveness of Oiva on working-age individuals with stress problems.

    CONCLUSIONS: A feasibility study of Oiva mobile mental wellness training app showed good acceptability, usefulness, and engagement among the working-age participants, and provided increased understanding on the essential features of mobile apps for stress management. Five design implications were derived based on the qualitative findings: (1) provide exercises for everyday life, (2) find proper place and time for challenging content, (3) focus on self-improvement and learning instead of external rewards, (4) guide gently but do not restrict choice, and (5) provide an easy and flexible tool for self-reflection.

    Oiva – A mobile phone intervention for psychological flexibility and wellbeing2012In: Designing for Wellness and Behavior Change workshop, 2012Conference paper (Other academic)
    Abstract [en]

    To provide a scalable solution to mental health problems caused by stress, we developed Oiva, a mobile phone intervention for improving mental and physical wellbeing. Oiva is based on Acceptance and Commitment Therapy (ACT) and its aim is to teach the users skills to increase their psychological flexibility. The application contains 45 text, audio, and video exercises. Two user studies demonstrated the usability and acceptability of the application and concept. The evaluations also revealed that the users expected guidance on the application for performing the intervention program. They also wanted to have possibilities to individualize the application by saving their own reflections about the exercises as notes. The preliminary evaluation results indicate that Oiva is a good starting point for the further design and research of mobile applications for reducing stress and improving wellness.

    The Stockholm Neonatal Project: Cognitive and executive functioning in adolecents born pretermManuscript (preprint) (Other academic)
    Abstract [en]

    Objective: Research has shown that premature birth poses a risk for later cognitive development, particularly in the executive domain, but few studies extend beyond the early school years. Adolescence is a critical period for cognitive maturation, and this study investigated the cognitive outcome in a Swedish cohort of prematurely born 18-year olds, in relation to gestational age at birth and medical risks in the perinatal period.

    Participants and Methods:  As part of Stockholm Neonatal Project, 134 adolescents born preterm with very low birth weight (< 1500g) and 94 matched controls born at term, participated in a follow-up study at age 18. General intelligence, as well as executive, memory, language and visual motor functions were measured by WISC-III, Delis-Kaplan Executive Function System, naming tests, Rey Auditory Verbal Learning test, face recognition, and Visual Motor Integration test.

    Results: Extremely preterm adolescents (EPT, GA 23-27, n=74) performed worse than adolescents born either very preterm or at term, on all cognitive tasks and particularly on executive measures. 50% of the EPT group had suffered perinatal medical complications, and had more pervasive cognitive deficits than EPTs with low medical risk.  By contrast, very preterm adolescents (GA 28-31; n=36) performed consistently on a par with the controls.  Moderately preterm with very low birth weight (GA 32-36; n=25), who had experienced varying degrees of intrauterine growth retardation, tended to score lower than very preterm and control adolescents, particularly on complex cognitive measures.

    Conclusions: Extremely preterm birth per se poses a risk for long-term cognitive outcome, particularly in executive functions. These risks may be exacerbated by medical complications.  Children born after 28 weeks of gestation or later, with normal birth weight and no perinatal complications, do not have an elevated risk for cognitive deficits at age 18.
