Clinical characteristics related to severity of sexual abuse: a study of seriously mentally ill youth.

OBJECTIVE In this study we examined demographic, social, and clinical variables related to sexual abuse histories in a sample of severely mentally ill youth. METHOD Data were collected via a retrospective chart review of all patients treated over a 5-year period (1987-1992) at a tertiary care public sector psychiatric hospital. The sample was divided into four groups: no history of sexual abuse (n = 226); isolated events (n = 62); intermittent abuse (n = 61); and chronic (n = 150). RESULTS Youth with sexual abuse histories were more often female, had higher rates of social chaos and associated physical abuse and neglect, and had higher rates of post-traumatic stress disorder (PTSD) and substance abuse disorders. Chronically abused subjects came from the most chaotic and abusive backgrounds; were younger when first abused; had the highest number of abusers; were more likely to have been molested; and were more often abused by their father/stepfather and/or their mother/stepmother. Using logistic regression analyses, sexual abuse histories were predicted by sexually inappropriate behaviors, symptoms of PTSD and borderline personality disorders, dissociative symptoms, substance abuse and animal cruelty. CONCLUSION Sexual abuse histories were quite common in this sample. Sexually abused subjects had increased rates of inappropriate sexual behaviors, substance abuse, and post-traumatic reactions; and were frequently exposed to other confounding environmental risk factors, including physical abuse, family problems and social chaos.
