The Effects of Prosocial Behavior on Mood and Prosociality in Individuals High in Borderline Personality Disorder Traits (HBTs)

With the hypothesis that prosocial behavior improves mood and engenders further prosocial behavior, this study examined effects of a prosocial manipulation (vs. a control manipulation) in a normative population, with oversampling for Borderline Personality Disorder traits. The manipulation improved mood but not subsequent prosocial behavior, regardless of borderline trait level.
