Research has implicated emotion regulation as having an important negative role in nonsuicidal self-injury (NSSI). A model using predictors of emotion regulation and personal vulnerability characteristics was examined to predict the occurrence of NSSI using self-report data collected via a web-based survey from 756 students at a rural northeastern university.
Results suggest that both discriminant analysis and logistic regression were similar at predicting NSSI with approximately 67% accuracy and support NSSI as a function of intrapersonal negative reinforcement. Specifically, indicators of poor psychiatric health, including higher levels of anxiety, avoidant behavior, rumination, depressive symptoms, trauma symptoms, and dissociation and lower levels of self-esteem increased the probability of NSSI. Furthermore, symptoms of depression, trauma, and dissociation were found to be an almost complete mediator between unproductive management of self-perceived distress and NSSI as well as a partial mediator between neurotic traits and NSSI. Indicators of psychopathology, self-perceived distress, and ineffective attempts at coping, whether constructive or non-constructive, appear to significantly contribute to increased risk of NSSI.
