Abstract

Individuals with bipolar disorder display both emotion regulation (ER) deficits and Behavioral Approach System (BAS) hypersensitivity. We examined associations between ER and the BAS among bipolar and control individuals. We compared 11 bipolar and 11 demographically matched control individuals using self-report BAS sensitivity and ER measures and reaction time (RT) and accuracy on the Affective Stroop Task, which examines the impact of emotional stimuli goal-directed processing while completing a numerical Stroop task. Between-group analyses indicated that bipolar subjects have ER difficulties not attributable to manic or depressive symptoms. Between-group analyses indicated that bipolar and control subjects did not differ significantly on RT or accuracy of performance on the Affective Stroop Task. However, bipolar participants, but not control participants, were significantly slower to respond to incongruent trials than congruent trials, regardless of emotion. Regression analyses indicated that, among bipolar participants but not control participants, self-reported ER difficulties and BAS sensitivity differentially predicted RTs. Results suggest a differential pattern of association between the BAS and the ER system among bipolar and healthy individuals.
