title: Predicting Nonsuicidal Self-Injury in Borderline Personality Disorder Using Ecological Momentary Assessment.
abstract: Borderline personality disorder (BPD) is a highly comorbid disorder, and these comorbidities increase the impairment associated with BPD. For example, depression, which occurs in the majority of individuals with BPD, increases the likelihood of an individual with BPD to engage in nonsuicidal self-injury (NSSI). Little research, however, has investigated potential mechanisms of NSSI engagement in this population. The current study aimed to fill this gap by examining momentary experiences, levels of distress tolerance, and NSSI among 51 individuals meeting current diagnostic criteria for BPD and a comorbid depressive disorder. Using data from an ecological momentary assessment across 7 days, it was found that daily urges to hurt oneself and impulsive urges, but not daily negative affect or aggressive urges, predicted NSSI occurrence. Furthermore, low levels of distress tolerance was a stronger predictor of NSSI behavior than daily experiences. These findings have important implications with regard to state versus trait dispositions in NSSI engagement among those with BPD and depression.
