Abstract

OBJECTIVE: Despite the well-established link between posttraumatic stress disorder (PTSD) and nonsuicidal self-injury (NSSI), little is known about factors that may lead to self-injury among trauma-exposed individuals. Moreover, no research to date has examined these relations in the context of the newly revised Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) PTSD criteria. Thus, the purpose of the current study was to explore the associations between DSM-5 PTSD symptom clusters (i.e., intrusion, avoidance, negative alterations in cognitions and mood, alterations in arousal and reactivity) and self-injury functions using a small sample of college students.

METHOD: Participants (N = 81) were recruited for a lifetime history of NSSI and trauma exposure.

RESULTS: Findings revealed a statistically significant path from PTSD avoidance symptoms to NSSI social functions and from PTSD negative alterations in cognitions and mood symptoms to NSSI intrapersonal functions, even after controlling for relevant covariates.

CONCLUSIONS: Results of the current study highlight the importance of assessing for NSSI among trauma-exposed individuals. Considering that NSSI is a risk factor for suicidal behavior and potentially a clinically distinct diagnosis, future research should continue to explore these associations using larger, more diverse clinical samples.
