    The meal pattern questionnaire: A psychometric evaluation using the eating disorder examination2016In: Eating Behaviors, ISSN 1471-0153, E-ISSN 1873-7358, Vol. 21, p. 7-10Article in journal (Refereed)
    Abstract [en]

    Objective

    Meal pattern is an important variable in both obesity treatment and treatment for eating disorders. Momentary assessment and eating diaries are highly valid measurement methods but often cumbersome and not always feasible to use in clinical practice. The aim of this study was to design and evaluate a self-report instrument for measuring meal patterns.

    Method

    The Pattern of eating item from the Eating Disorder Examination (EDE) interview was adapted to self-report format to follow the same overall structure as the Eating Disorder Examination Questionnaire. The new instrument was named the Meal Patterns Questionnaire (MPQ) and was compared with the EDE in a student sample (n = 105) and an obese sample (n = 111).

    Results

    The individual items of the MPQ and the EDE showed moderate to high correlations (rho = .63–89) in the two samples. Significant differences between the MPQ and EDE were only found for two items in the obese sample. The total scores correlated to a high degree (rho = .87/.74) in both samples and no significant differences were found in this variable.

    Discussion

    The MPQ can provide an overall picture of a person's eating patterns and is a valid way to collect data regarding meal patterns. The MPQ may be a useable tool in clinical practice and research studies when more extensive instruments cannot be used. Future studies should evaluate the MPQ in diverse cultural populations and with more ecological assessment methods.

    Is age a better predictor of weight loss one year after Gastric bypass than symptoms of disordered eating, depression, adult ADHD, and alcohol consumption?2014In: Eating Behaviors, ISSN 1471-0153, E-ISSN 1873-7358, Vol. 15, no 4, p. 644-647Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION:

    Findings regarding psychological risk factors for low weight loss after bariatric surgery have been inconsistent. The association between gender and weight outcome is unclear while younger age has been consistently shown to be associated with better weight outcome. The aim of this study was to analyze the interactions between gender and age on the one hand and symptoms of disordered eating, depression, adult ADHD and alcohol consumption on the other hand in regard to weight loss after gastric bypass.

    METHODS:

    Bariatric surgery patients were recruited and asked to fill out self-report questionnaires regarding behavioral risk factors before and twelve months after surgery. Data from one hundred and twenty-nine patients were analyzed.

    RESULTS:

    After controlling for age, no psychological variable measured prior to surgery could predict weight loss after twelve months. After surgery, there was an interaction effect between age, gender and specific eating disorder symptoms. Specifically, loss of control over eating was a risk factor for low weight loss among older, but not among younger, female participants. Symptoms of adult ADHD were associated with elevated alcohol consumption after surgery.

    DISCUSSION:

    These results indicate that age and gender may moderate the effects of potential risk factors for inferior weight outcome. This interaction could potentially be one of the reasons behind the mixed findings in this field. Thus, there are important gender differences in the bariatric population that should be considered. The present study is the first to show that symptoms of adult ADHD may not be a risk factor for inferior weight loss but for alcohol risk consumption after gastric bypass.

    Negative self-image and outcome in eating disorders: results at 3-year follow-up.2007In: Eating Behaviors, ISSN 1471-0153, E-ISSN 1873-7358, Vol. 8, no 3, p. 398-406Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: Negative self-image has been hypothesised to be of aetiological significance in eating disorders; however, its relationship to outcome remains unclear. The present study examined the relationship between self-image and follow-up status in a heterogeneous sample of eating disorder patients (N=246). METHODS: Patients were assessed at intake and after 36 months. Self-image was measured using SASB, and a general outcome measure was calculated comprising eating disorder symptoms, occupational status, interpersonal relationships and general psychopathology. RESULTS: SASB self-hate was the most important variable for predicting poor outcome, followed by occupational status, interpersonal relationships, eating disorder symptoms, SASB self-emancipation and general psychiatric symptoms. Together these variables predicted 23% of the variance in outcome. DISCUSSION: High levels of self-hate may increase the risk of poor outcome in eating disorders by adversely affecting interpersonal relationships and making it difficult for patients to engage in treatment.

    Binge eating in surgical weight-loss treatments: Long-term associations with weight loss, health related quality of life (HRQL), and psychopathology2009In: Eating Behaviors, ISSN 1471-0153, E-ISSN 1873-7358, Vol. 7, no 1, p. 15-26Article in journal (Refereed)
    Abstract [en]

    Objective Previous studies that have investigated the relationshipbetween binge eating and the long-term outcome of bariatric surgeryhave shown mixed results. Does binge eating before or after bariatricsurgery affect long-term BMI, health-related quality of life (HRQL), orpsychopathology after surgery? The objective of the present studywas to address these questions to determine the extent to whichbinge eating needs to be addressed in the context of bariatric surgeryMethods. We assessed 173 bariatric patients before and three yearsafter weight loss surgery with regard to weight, binge eating, HRQL,and psychopathology.Results. Binge eating habits before and after weight loss surgerywere unrelated to the long-term BMI outcome. Binge eating afterweight loss surgery was associated with more psychopathology and alower HRQL.Conclusion. Binge eating before or after weight loss surgery doesnot predict long-term BMI outcome. Therefore, exclusions fromsurgery for this reason alone are difficult to motivate. However,results show that binge eating after weight loss surgery is commonand is associated with both more psychopathology and a lower HRQL.The poor psychological health status of patients that binge eat afterweight loss surgery motivates studies with longer follow-up periods toinvestigate whether post-surgical binge eating might increase thevulnerability to future weight regain and complications at time pointsbeyond three years. The high rate of binge eating after surgery andits negative association with the HRQL and psychopathology indicatethat we need to be observant of the occurrence and potential effectsof binge eating in the context of bariatric surgery.

    Eating disorders and disordered eating among patients seeking non-surgical weight-loss treatment in Sweden2006In: Eating Behaviors, ISSN 1471-0153, E-ISSN 1873-7358, Vol. 7, no 1, p. 15-26Article in journal (Refereed)
    Abstract [en]

    The aim of this cross-sectional descriptive study of 194 Swedish men and women seeking non-surgical weight-loss treatment was to investigate the presence of eating disorders and binge eating symptoms and to compare these two groups of patients with a group without eating disorder- or binge eating symptoms. The groups were compared in regard to co-morbid psychopathology, Health Related Quality of Life (HRQL) and anthropometric data. Of the total sample, 9.8% fulfilled criteria for any eating disorder. An additional 7.2% indicated binge eating symptoms without having an eating disorder. The three groups were significantly different in regard to psychopathology scales and most HRQL items. Eating disorders and binge eating symptoms are common among patients seeking non-surgical weight-loss treatments in Sweden and both groups showed elevated levels of co-morbid psychopathology and lower HRQL compared to patients without disordered eating. These findings point to the importance of assessing the full range of eating disorder symptoms and disorders as well as HRQL and co-morbid psychopathology before weight-loss treatment, as these factors might affect treatment outcome.

    An obesity provoking behaviour negatively influences young normal weight subjects' Health Related Quality of Life and causes depressive symptoms2010In: Eating Behaviors, ISSN 1471-0153, E-ISSN 1873-7358, Vol. 11, no 4, p. 247-252Article in journal (Refereed)
    Abstract [en]

    In many parts of the world the prevalence of a sedentary lifestyle in combination with high consumption of food has increased, which contributes to increased risk for becoming overweight. Our primary aim was, in an intervention, to examine the influence on health related quality of life (HRQoL) and mood in young normal weight subjects of both sexes, when adopting an obesity provoking behaviour by increasing the energy intake via fast food and simultaneously adopting a sedentary lifestyle. A secondary aim was to follow-up possible long-term effects on HRQoL and mood 6 and 12 months after this short-term intervention.

    In this prospective study, 18 healthy normal weight subjects (mean age 26 ± 6.6 years), mainly university students were prescribed doubled energy intake, and maximum 5000 steps/day, during 4 weeks. An age and sex matched control group (n = 18), who were asked to have unchanged eating habits and physical activity, was recruited. Before and after the intervention questionnaires including Short Form-36, Hospital Anxiety Depression scale, Center of Epidemiological Studies Depression scale, Sense of Coherence and Mastery scale were completed by the subjects in the intervention group and by the controls with 4 weeks interval. Six and 12 months after the intervention the subjects underwent the same procedure as at baseline and the controls completed the same questionnaires.

    During the intervention, subjects in the intervention group increased their bodyweight and developed markedly lower physical and mental health scores on Short Form-36 as well as depressive symptoms while no changes appeared in the controls. The increase of depressive symptoms was associated with increases of energy intake, body weight and body fat. When followed up, 6 and 12 months after the intervention, physical and mental health had returned completely to baseline values, despite somewhat increased body weight.

    In conclusion, adopting obesity provoking behaviour for 4 weeks decreases HRQoL and mood in young normal weight subjects. The effect is temporary and when followed up 6 and 12 months after the short-term intervention no remaining influence is found.

    Stroop interference for food- and body-related words: A meta-analysis2005In: Eating Behaviors, ISSN 1471-0153, E-ISSN 1873-7358, Vol. 6, no 3, p. 271-281Article in journal (Refereed)
    Abstract [en]

    According to cognitive theories of eating disorders, biased information processing in favour of dysfunctional attitudes about food and body appearance plays a vital role in the development and maintenance of such disorders. Data from 27 studies evaluating Stroop interference for food- and body-related words with negative overtones were included in a meta-analysis in order to investigate whether such processing biases are specific to eating disordered samples. Participants were females characterised as eating disordered, non-eating disordered but nevertheless over-concerned with body appearance and eating, and normal controls. Mean Stroop interference for eating disordered females was of medium effect size (Cohen's d=0.48) and significantly larger than for both non-eating disordered females concerned with body appearance and eating, and normal control females (both d=0.21). Stroop interference for eating disordered females was thus of fairly modest magnitude where it was unclear whether such interference is specific to this sample. © 2004 Elsevier Ltd.

    The role of sensitivity to external food cues in attentional allocation to food words on dot probe and Stroop tasks2004In: Eating Behaviors, ISSN 1471-0153, E-ISSN 1873-7358, Vol. 58, p. 261-271Article in journal (Refereed)
    Abstract [en]

    The role of sensitivity of external food cues in producing attentional bias toward food-, body-weight-, and shape-related words on the Stroop and the dot probe tasks was examined. Contrary to expectations, individuals high in responsiveness to external food cues directed attention away from food words, whereas individuals low in responsiveness to external food cues directed their attention toward food words on the dot probe task. No significant differences were found between the groups high and low in sensitivity to external food cues for body words on the dot probe task or for food or body words on the Stroop task. Results are discussed with reference to theoretical views of differences between the Stroop and the dot probe tasks.

    Self-image and eating disorder symptoms in normal and clinical adolescents2014In: Eating Behaviors, ISSN 1471-0153, E-ISSN 1873-7358, Vol. 15, no 1, p. 125-131Article in journal (Refereed)
    Abstract [en]

    Eating disorders (ED) are psychiatric disorders of multifactorial origin, predominantly appearing in adolescence. Negative self-image is identified as risk factor, but the association between self-image and ED in adolescents or sex differences regarding such associations remains unclear. The study aimed to investigate the relationship between specific self-image aspects and ED symptoms in normal and clinical adolescents, including sex differences. Participants included 855 ED patients (girls = 813, boys = 42) and 482 normal adolescents (girls = 238, boys = 244), 13-15 years. Stepwise regression demonstrated strong associations between self-image and ED in normal adolescents (girls: R-2 = .31, boys: R-2 = .08), and stronger associations in patients (girls: R-2 = .64, boys: R-2 = .69). Qualitative sex differences were observed in patients. Connections between specific self-image aspects and ED have implications for clinical management of ED. The strong link between self-image variables and ED symptoms in normal girls, but not boys, is discussed in terms of the continuity-discontinuity hypothesis.

    Assessment of parental overt and covert control of child's food intake: A population-based validation study with mothers of preschoolers2014In: Eating Behaviors, ISSN 1471-0153, E-ISSN 1873-7358, Vol. 15, p. 673-678Article in journal (Refereed)
    Abstract [en]

    Introduction: Overt and covert control are novel constructs representing two different parental feeding practices with regard to the child's ability to detect them. Preliminary research indicates that covert control is linked to a healthier diet and lower child weight status. In this study,we report the first psychometric validation of the original measures of overt and covert control outside the UK in a large sample of parents of preschoolers.

    Methods: Based on records from the population register, all mothers of 4-year-olds (n = 3007) from the third largest city in Sweden,Malmö, were contacted by mail. Out of those, 876 returned the measures of overt and covert control together with a background questionnaire and the Child Feeding Questionnaire (CFQ). Test–retest data were obtained from 64% (n = 563) of these mothers. The mean age of the mothers was 35.6 years; their mean BMI was 24.1, 31.5% were overweight or obese. The children were on average 4.5 years old; 48% were girls, 12.8% were overweight or obese.

    Results: While the fit for the original 9-item 2-factor model was poor, shorter 8- and 6-item versions were supported by confirmatory factor analysis (CFI N 0.95, RMSEA b 0.05). Internal and test–retest reliability of the shorter version was good (ICC= 0.65–0.71). Results also suggest that the factor structure and loadings were invariant (i.e., did not significantly differ) over time and between child sexes. Both overt and covert control factors were moderately correlated with CFQ monitoring. Overt control was also moderately related to CFQ pressure and weakly correlated with CFQ restriction. Covert control, on the other hand, was moderately related to restriction and not related with pressure. Correlations of both factors with child and parent BMI were very small.

    Conclusion: We found good psychometric properties of the revised versions of the overt and control behaviors in a multiethnic sample of mothers from Sweden. Future studies need to establish causal associations between overt and covert control and the obesity related outcomes.

    Alexithymia and emotional awareness in anorexia nervosa: time for a shift in the measurement of the concept?2010In: Eating Behaviors, ISSN 1471-0153, E-ISSN 1873-7358, Vol. 11, no 4, p. 205-210Article in journal (Refereed)
    Abstract [en]

    The present study compared 35 patients with anorexia nervosa (AN) with an age matched control group using the Toronto Alexithymia Scale (TAS-20; a self-report instrument) and the Levels of Emotional Awareness Scale (LEAS; a performance-based instrument). Depression and anxiety have been shown to account for elevated levels of alexithymia in AN, and an elevated level of perfectionism might affect self-reporting in general. The AN-group reported a higher level of alexithymia on the TAS-20 compared to the control group, a difference that disappeared after controlling for depression or anxiety (but not for perfectionism). The findings suggest that the AN-patients believe that they have difficulties in identifying and reporting emotions, but actually perform as well as the control group when confronted with the task of identifying and reporting their emotions according to LEAS. It might be time to rethink the measurement of alexithymia. Maybe, similar to assessment of personality disorders, it should not be assessed when patients are depressed, or it should be assessed through instruments and modalities that are not sensitive to the mood state of the patient.

    Description of an intensive nutrition therapy in hospitalized adolescents with anorexia nervosa2016In: Eating Behaviors, ISSN 1471-0153, E-ISSN 1873-7358, Vol. 21, p. 172-178Article in journal (Refereed)
    Abstract [en]

    Objective: To describe an intensive nutrition therapy for hospitalized adolescents and young adults with anorexia nervosa (AN) in terms of body weight, body composition, energy balance and food related anxiety. Method: Twenty-six young females, 16-24 years of age, with AN were invited to participate at admission to a specialized eating disorder unit in Goteborg, Sweden. Intensive nutrition therapy comprised 12 weeks on a structured meal plan. Six meals were served daily, in combination with high-energy liquid nutritional supplements from start. Energy and nutrient intakes, energy expenditure, body composition and food related anxiety were measured during the study. A 3-month follow-up of body weight and food related anxiety was conducted. Results: Twenty-one patients participated. The total daily energy intake was, during the first week of treatment, (mean +/- SD) 3264 +/- 196 kcal (74 kcal/kg), and decreased gradually during treatment to 2622 +/- 331 kcal (49 kcal/kg). Total daily energy expenditure was initially 1568 +/- 149 kcal and increased gradually to 2034 +/- 194 kcal. Patients gained on average 9.8 +/- 2.1 kg and body mass index increased from 15.5 +/- 0.9 to 19.0 +/- 0.9 kg/m(2). Body fat increased from 13 +/- 6% to 26 +/- 6%. Fat free mass remained unchanged, but skeletal muscle mass increased from 16.7 +/- 2.0 to 17.6 +/- 2.4 kg, p = 0.009. Patients food related anxiety decreased significantly during treatment and was still unchanged 3 months later. Conclusion: The presented intensive nutrition therapy with initially high energy and nutrient intakes produced substantial weight gain, increased fat and muscle mass and decreased food related anxiety in AN patients, without any clinical side effects.

    Flexibility in weight management.2014In: Eating Behaviors, ISSN 1471-0153, E-ISSN 1873-7358, ISSN 1471-0153, Vol. 15, no 2, p. 218-24, article id S1471-0153(14)00022-1Article in journal (Refereed)
    Abstract [en]

    The purpose of the study was to investigate the relationships between changes in flexible vs. rigid restraints of eating during weight management, as well as how changes in the cognitive restraint of eating were related to psychological well-being and flexibility. The data includes information on 49 overweight persons who participated in a weight loss and maintenance (WLM) intervention and a follow-up assessment after 8-9 months. An increase in flexible cognitive restraint during the weight loss intervention was related to better weight loss maintenance and well-being. The more flexible restraint increased during the WLM intervention, the more psychological distress decreased. Moreover, larger reduction of rigid restraint during the follow-up period (between the WLM intervention and the follow-up assessment) was related to a better maintenance of improved psychological well-being at the follow-up endpoint. These results suggest that increasing flexible control while reducing rigid control of eating after an active weight loss phase improves success in weight management and the psychological well-being of weight losers.

    Does perfectionism mediate or moderate the relation between body dissatisfaction and disordered eating attitudes and behaviors?2009In: Eating Behaviors, ISSN 1471-0153, E-ISSN 1873-7358, Vol. 10, no 3, p. 168-175Article in journal (Refereed)
    Abstract [en]

    A link between perfectionism and disordered eating has been documented in previous studies. The purpose of the current study was to expand our knowledge of the specific role of perfectionism in disordered eating by examining perfectionism as a mediator or a moderator in the relation between body dissatisfaction and disordered eating (assessed using the EAT-26 and its subscales. and the Binge Scale) We sampled a large ethnically diverse sample of university women (N = 520) using two measures of perfectionism the Eating Disorder Inventory Perfectionism subscale (EDI-P) and the Multidimensional Perfectionism Scale (H-MPS) In general, socially prescribed and self-oriented perfectionism, but not other-oriented perfectionism, were correlated with disordered eating attitudes and behaviors, except binge eating. Furthermore, perfectionism was found to partially mediate and moderate the relation between body dissatisfaction and disordered eating, however the strength of these associations differed depending on both the particular measure of perfectionism (EDI-P versus H-MPS) and the specific dimension of perfectionism (self-oriented, socially prescribed, other-oriented) used in the analyses. The findings are discussed in relation to the need for more informed and theoretically sound models of the development and maintenance of disordered eating.
