RESUMO
Possible mediators of sexual abuse severity were tested on the basis of D. Finkelhor and A. Browne's (1985) traumagenic dynamics model with 178 low-income African American, European American, and Mexican American community women interviewed for Project HOW: Health Outcomes of Women. This subsample reported contact sexual abuse before the age of 18 years. Severity was level of force, number of perpetrators, relationship to perpetrator, and age at first assault. As expected, structural equation modeling showed powerlessness, and stigmatization largely mediated the effects of sexual abuse severity on women's psychological distress in adulthood. Powerlessness also mediated the effects of severity on maladaptive social relationships. The expected path from betrayal to relationships was nonsignificant. Overall, the results support extension of D. Finkelhor and A. Browne's model. Possible interventions are addressed.
