Affect regulation and Depressive Personality Disorder.

Depressive Personality Disorder (DPD) has been under consideration for inclusion in the Diagnostic and Statistical Manual of Mental Disorders since 1994; yet, few studies have been published that test whether those with DPD have affective experiences that are characterized exclusively by depression and negative affect. One hundred ninety-seven undergraduate students were interviewed for DPD and Borderline Personality Disorder with the Personality Disorder Interview for DSM-IV (Widiger, Mangine, Corbitt, Ellis, & Thomas, 1995), in order to control for frequently co-occurring BPD which is characterized by affective lability. Participants also were administered measures of affective lability, affective intensity, anxious and depressive states, and more trait-like manifestations of depression, anxiety, and anger. Results indicate that those with DPD may be described as having a mood state characterized by transitions from a baseline neutral mood to one of anxiety, with their experiences being more prominently depressed and dysphoric. They also have tendencies toward angry hostility, though they may not report frequent shifts from a baseline neutral mood to anger. Those with DPD also report intense, frequent experiences of depression and dysphoria, with many shifts between depression and anxiety.
