The current study sought to identify clusters of incarcerated men based on history and functions of non-suicidal self-injury (NSSI). Functions of NSSI are considered to be either automatic (i.e., intrapersonal) or social (i.e., interpersonal). NSSI is highly prevalent within forensic populations, and is associated with significant financial and psychological burden on the inmates and correctional institutions. However, few studies have examined men and none have examined function of NSSI within this population. Ninety-five incarcerated men completed measures of NSSI as well as pertinent environmental and personality variables. Approximately two-thirds of the sample reported a history of NSSI. Within the inmates with histories of NSSI, a model-based cluster analysis identified four groups comprising different levels, type counts, and functions of NSSI. Following external validation procedures, three of the groups reported higher general psychopathology, while one NSSI group was similar in profile to the Non-NSSI Comparison Group. Implications for prevention and intervention are discussed.
