Abstract

Using a sample of 154 Dutch forensic psychiatric outpatients aged 18-62 years, this study investigated whether risk factors of posttraumatic stress disorder (PTSD), mainly identified in nonforensic research, forensic psychiatric factors, and potential comorbid mental disorders were associated with PTSD. Data on demographics, victimization during childhood or adolescence, and forensic psychiatric factors were derived from electronic medical records. Mental disorders were assessed using structured psychiatric interviews and consensus diagnoses were established during weekly case consultations. The PTSD rate was 75% in the sample. Whereas the PTSD group was significantly more likely to be older, female, not Dutch, and to have a history of victimization, previously perpetrated family violence, and lower psychosocial and occupational functioning than the non-PTSD group, the latter group had significantly higher rates of psychiatric history, attention-deficit/hyperactivity disorder (ADHD), antisocial personality disorder, drug abuse, and previous repeated nonfamily violence perpetration. Effect sizes ranged from Nagelkerke R 2 = .04 for psychosocial and occupational functioning to Nagelkerke R 2 = .70 for ADHD. This study demonstrated differences between those with and without PTSD in demographic, victim, forensic, and psychological characteristics. Future studies should examine the complexity between early victimization, delinquency patterns, and psychopathology regarding the prediction of PTSD among forensic psychiatric outpatients.
