Abstract: Objective: Although not all trauma-exposed individuals develop posttraumatic stress disorder (PTSD) symptoms or NSSI, it has been suggested that those who use NSSI as a means of coping with PTSD symptoms increase their acquired capability for suicide. This study sought to test the relationship between PTSD symptom clusters, functions of NSSI, and suicide capability (i.e., fearlessness about death [FAD]) in a trauma-exposed sample of individuals with a history of self-injury. Method: = 3.28). Participants were primarily female (86.2%). Most identified as White (81%), 12.1% identified as African American/Black, 1.7% as Asian, 1.7% as American Indian/Alaskan Native and 3.5% of identified as Biracial. A parallel mediation model was employed. Results: Global PTSD symptoms exhibited a statistically significant positive relationship with intrapersonal (e.g., emotion regulation) and interpersonal (e.g., social) functions of NSSI. However, only intrapersonal functions were statistically significantly related to FAD. Although PTSD symptoms did not demonstrate a direct relationship with FAD, there was an indirect effect of PTSD symptoms on FAD through intrapersonal functions of NSSI. Conclusions: Engaging in NSSI for the purpose of managing PTSD symptoms may contribute to FAD beyond the presence of PTSD symptoms or NSSI. Clinical interventions that promote adaptive emotional regulation strategies may help to thwart increases in FAD for trauma-exposed samples.
