Components of emotion dysregulation in borderline personality disorder: a review.

Following Linehan's biosocial model, we conceptualize emotion dysregulation in borderline personality disorder (BPD) as consisting of four components: emotion sensitivity, heightened and labile negative affect, a deficit of appropriate regulation strategies, and a surplus of maladaptive regulation strategies. We review the evidence supporting each of these components. Given the complexity of the construct of emotion dysregulation and its involvement in many disorders, there is a need for research that specifies which components of emotion dysregulation are under study and also examines the interplay amongst these emotion dysregulation components.
