Childhood trauma, traumatic brain injury, and mental health disorders associated with suicidal ideation and suicide-related behavior in a community corrections sample.

Suicidal ideation and suicide-related behavior among community-supervised offenders are significant public health problems. In a sample of 418 subjects served by the community corrections office of Iowa's Sixth Judicial District, 56 percent of subjects denied suicidal ideation and suicide-related behavior (control group), 17 percent reported suicidal ideation without suicide-related behavior (ideator group), and 27 percent reported engaging in suicide-related behavior (actor group). A model comprising five independent variables differentiated the ideator and actor groups from the control group: Caucasian race, depressive symptom sum, brain injury, childhood trauma, and avoidant personality. These five factors, combined with the additional variables of PCL:SV Factor 2 (Psychopathy Checklist-Screening Version) score and lifetime anxiety disorder, differentiated the actor group from the control group.
