Boredom in Borderline Personality Disorder: A Lost Criterion Reconsidered.

Difficulty with boredom was eliminated from the formal diagnostic criteria for borderline personality disorder (BPD) in 1994 based on significantly limited, unpublished data. However, it is apparent in clinical practice that boredom remains relevant to BPD. This review synthesizes empirical research, with consideration of theoretical accounts, to critically examine the relevance of boredom to BPD. We first briefly review issues in defining and measuring boredom and offer an expanded conceptualization for BPD, which includes the notion of boredom reactivity, before turning to boredom's differentiation from and overlap with feelings of emptiness, with which it was paired prior to its removal from the DSM. We then discuss perspectives on boredom's significance in BPD, briefly touching on its relevance in other personality disorders. We propose a Boredom Cascade Model that articulates how boredom and boredom reactivity interact with identity disturbance and chronic emptiness to create escalating patterns of behavioral dysregulation and make recommendations for research and treatment.
