The Psychiatric Consequences of Child and Adolescent Sexual Abuse

Introduction: The purpose of this study was to investigate the psychiatric consequences of sexual abuse and its associated factors in children and adolescents referred to our child and adolescent psychiatry clinic from official medico-legal units. Methods: All victims of sexual abuse (n=590) aged 1-18 (mean: 13.56 +/- 3.38) referred from forensic units to Ondokuz Mayis University Child and Adolescent Psychiatry Clinic over a period of 2 years [boys: 83 (14.1%); girls: 507 (85.9%)] were included. Child and adolescent psychiatry and forensic medicine specialists evaluated all the cases. The Wechsler Intelligence Scale for Children-Revised Form (WISC-R) and the Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version-Turkish Version (K-SADS-PL-T) were applied. Results: Abuse-related psychiatric diagnoses (of which 45.9% were major depressive disorder and 31.7% were post-traumatic stress disorder cases) were made in 75.2% of the cases. In 80.3% of the cases, the perpetrators were known to their victims [incest, n=91 (15.1%)], and intercourse took place in 48.8%. Although gender and age were not significantly associated with the appearance of any psychiatric disorders, severity of abuse (e.g., intercourse; p=.006), additional physical assault (p<.001), and incest (p<.001) had a significant correlation with psychiatric disorders. To explore the predictive value of multiple factors in the appearance of any sexual assault-related psychiatric disorder, a logistic regression model was used to determine the best linear combination of age, gender, abuse severity, incest, involvement of any other victim, additional physical assault, and length of time from first abuse to first psychiatric evaluation. This combination of variables (occurrence of incest, additional physical assault, and a long duration from first abuse to first psychiatric evaluation) significantly predicted the appearance of a psychiatric disorder of any kind (chi(2)=55.42; df=7; n=522; p<.001). Conclusion: Our findings reveal that the occurrence of incest, additional physical assault, and a long duration from first abuse to first psychiatric evaluation predict higher rates of sexual abuse-related psychiatric disorders.
