Inmate Self-Injurious Behaviors: Distinguishing Characteristics Within a Retrospective Study

The current study examines demographic, health functioning, and criminogenic correlates of self-injurious behaviors. Incident reports for all 28 South Carolina correctional facilities were collected during a 30-month period, evidencing 189 inmates who self-injure contrasted with 22,794 inmates who do not. Self-injury was significantly associated with the disproportionate utilization of health resources, specifically through major mental health treatment and institutional restriction. Characteristics of incarcerated self-injurers revealed discernible maladjustment to the correctional milieu, with each self-injury incident being associated with a 37% increase in the number of disciplinary incidents. Moreover, the earlier incarceration period represented a period of greater risk. Each additional year in prison was associated with a 25% increase in self-injurious events, which then declined with further years of imprisonment. These unique characteristics are discussed, and salient policy implications are recommended.
