0108 INFLUENCE OF SLEEP DEPRIVATION ON EMOTION REGULATION STRATEGIES: AN EVENT-RELATED POTENTIAL STUDY

The late positive potential (LPP) is a sustained positive deflection in the event-related potential that is larger following the presentation of emotional compared to neutral visual stimuli. Recent studies have indicated that the magnitude of the LPP is sensitive to emotion regulation strategies such as reappraisal, which involves generating an alternate interpretation of emotional stimuli so that they are less negative. It is unclear, however, whether reappraisal-related reductions in the LPP reflect reduced emotional processing or increased cognitive demands following reappraisal instructions. In the present study, we sought to examine whether a more or less negative description preceding the presentation of unpleasant images would similarly modulate the LPP. The LPP was recorded from 26 subjects as they viewed unpleasant and neutral International Affective Picture System images. All participants heard a brief description of the upcoming picture; prior to unpleasant images, this description was either more neutral or more negative. Following the more neutral description, the magnitude of the LPP, unpleasant ratings, and arousal ratings were all reliably reduced. These results indicate that changes in narrative are sufficient to modulate the electrocortical response to the initial viewing of emotional pictures, and are discussed in terms of recent studies on reappraisal and emotion regulation.

Nonsuicidal Self Injury

Abstract. Background: Nonsuicidal self-injury (NSSI) has been found to be associated with poor emotion regulation. Aims: The goal of this study was to examine the association of multidimensional cognitive emotion regulation strategies with NSSI among adolescents and compare the different patterns of NSSI. Method: A sample of 594 high-school students (54.4% boys; mean age = 14.96 years), from five regional schools across Israel, were assessed for five facets of cognitive emotion regulation strategies (acceptance, refocus on planning, positive refocusing, putting into perspective, and positive reappraisal) and NSSI behaviors using validated scales. Participants were allocated into three groups: repetitive NSSI (more than six occasions of NSSI; 7.1%), occasional NSSI (at least one incident but less than six; 8.3%), and no NSSI (84.6%). Results: Analysis of covariance, controlling for gender and depression symptoms, revealed that students with NSSI reported higher levels of acceptance, but lower levels of refocus on planning and putting into perspective. Limitations: The study used a cross-sectional design, which was a limitation. Conclusion: These findings demonstrate that particular cognitive emotion regulation strategies differ substantially in their relationship with NSSI. Adolescents who focus on planning and putting stressful situations into perspective may have increased resilience, whereas adolescents who are accepting of negative events that have happened may be more prone to maladaptive coping behaviors.
