Özet:
Bulimia and non-suicidal self-injury are behaviors that frequently co-occur among young adults. The proposed study aimed to identify etiological pathways that may account for the co-occurrence of bulimia and non-suicidal self-injury (NSSI) among 429 participants recruited from an undergraduate and community sample. Previous research has indicated negative affect, distress tolerance, negative urgency, and body dissatisfaction are independent risk factors for these outcomes. However, the specific contributions of these risk factors within the relationship between bulimia and NSSI is not fully understood. Negative affect was hypothesized to predict NSSI via body dissatisfaction and bulimia. Negative urgency and distress tolerance were expected to predict NSSI directly, as well as indirectly, via bulimia. A 3-way interaction between bulimia, negative urgency, and distress tolerance was hypothesized to predict NSSI, where all lower order interactions were expected to be significant predictors. Path model analysis examined the relationship between these variables and NSSI. Following bootstrap analysis, the 3-way interaction was not significant in predicting, or correlated with NSSI, so it was removed from the final model to ensure a parsimonious fit. Lower order interactions were examined. Consistent with hypotheses, negative affect indirectly predicted NSSI via body dissatisfaction and bulimia, with additional paths observed through negative urgency. Additionally, negative urgency directly and indirectly predicted NSSI via bulimia. Conversely, distress tolerance did not indirectly predict NSSI via bulimia, although a significant direct path to NSSI was observed. Of the hypothesized interactions, only the hypothesized bulimia x distress tolerance interaction was significant, where the positive relationship between bulimia and NSSI was strongest for individuals with lower distress tolerance. Interestingly, at low levels of bulimia symptoms, lower levels of distress tolerance exacerbated the risk of NSSI engagement. Findings contribute to etiological models of emotion dysregulation and body dissatisfaction within the co-occurrence of bulimia and NSSI. Emotion regulation risk factors of distress tolerance and negative urgency uniquely predict bulimia symptoms. Notably, negative urgency significantly predicts likelihood in NSSI engagement, while the role of distress tolerance may be more contingent on the presence of bulimia symptoms.
