Abstract [en]

Background: Neurophysiological research implicates sleep deprivation in emotion dysregulation. Less is known about the effects of partial sleep deprivation on the emotions and on emotion regulation of otherwise healthy people. An experimental, randomized pretest-posttest study design was used to examine the differential effects of partial sleep deprivation on emotion experience and implicit emotion regulation following emotion elicitation.

Methods: We randomized 81 healthy adults (44 females) into a sleep deprivation or rested condition. Sleep deprivation was defined as 3-nights with 5-hours total time in bed. Scores on positive and negative emotion markers measured emotions. Mixed between-within subjects analyses of variance were used to examine group differences in emotion following the sleep condition and after the emotion elicitation procedures and test.

Results: Sleep deprived people reported significantly less positive emotions, and more fatigue, irritability, and hostility compared to people who were rested following the sleep condition. There were negligible differences between groups in implicit emotion regulation following emotion elicitation.

Conclusions: These findings suggest that partial sleep deprivation is a potent stressor in emotion dysregulation through reductions in positive emotions. It also appears that implicit emotion regulation works equally well following strong negative emotional events, regardless of sleep condition. From a clinical perspective, sleep deprivation and ensuing reductions in positive affect and emotion may provide clinicians with viable targets in depression treatment. Keywords: Experimental, sleep deprivation, affect, emotions, emotion regulation, emotion elicitation.

Abstract [en]

Sleep disturbances are not only defining features, but also diagnostic criteria for most psychiatric disorders. Recently, researchers have proposed a theoretic role for sleep disturbances in emotion dysregulation, subsequently linking neurobiological processes and psychopathology. Most prior research examining the potential role for sleep disturbance in emotion dysregulation is from a neurophysiological or clinical perspective, or primarily focused on maintaining processes. Less well understood are how sleep disturbances may be involved at the levels of predisposition, precipitation, and perpetuation of emotion dysregulation concurrently and over time.

This dissertation presents findings from three studies that were designed to expand on what is known about sleep disturbance in the predisposition, precipitation, and perpetuation of emotion dysregulation. Study 1 examined the long-term relation between sleep-onset problems and neuroticism over twenty-years. Adolescent sleep-onset posed risk (predisposition) for neuroticism in midlife, not vice versa. Study 2 investigated the effects of 3-nights partial sleep deprivation (5-hours total time in bed) on the positive and negative affect and emotions of otherwise healthy adults. Following partial sleep deprivation, people reported significant reductions in positive affect and emotions compared to rested people (precipitation). The only impact on negative emotions was on the discrete level. Sleep deprived peo-ple reported significantly more irritability, loathing, hostility, and shakiness compared to controls. Study 3 measured adolescent sleep disturbances, depressive symptoms, and catastrophic worry. In addition to direct risk, sleep disturbances posed a non-gender specific risk for depressive symptoms one-year later through catastrophic worry (perpetuation). Overall, the results provide support for the role of sleep disturbances in the predis-position, precipitation, and perpetuation of emotion dysregulation. An implication is that sleep disturbances and catastrophic worry are two po-tentially modifiable markers of risk for emotion dysregulation.
