Borderline personality disorder and self-conscious affect: Too much shame but not enough guilt?

Shame has emerged as a particularly relevant emotion to the maintenance and exacerbation of borderline personality disorder (BPD) features; however, little attention has been paid to the potentially differing effects of other forms of self-conscious affect. While guilt has been demonstrated to have adaptive functions in the social psychology literature, it has not been previously explored whether a lack of socially adaptive guilt might also contribute to BPD-related dysfunction. The present study examined the relationship between BPD features and self-conscious emotions in a sample of undergraduate students (n = 839). Increased shame and decreased guilt independently accounted for significant variance in the association between BPD features and anger, hostility, and externalization of blame. Only increased shame significantly mediated the association between BPD features and anger rumination, and only decreased guilt significantly mediated the relationship between BPD features and aggression. These findings suggest BPD and its associated problems with anger and externalizing may be characterized not only by high levels of shame, but also by lower levels of guilt. Clinical implications include the need to differentiate between self-conscious emotions and teach adaptive responses to warranted guilt. (PsycINFO Database Record
