Sister-brother Incest: Data from Anonymous Computer Assisted Self Interviews

Abstract

Retrospective data were entered anonymously by 1,178 adult men using computer-assisted self-interview. Twenty-seven were victims of sister-brother incest (SBI), 119 were victims of child sexual abuse by an adult female (CSA-AF) before 18 years of age, 1,032 were controls. SBI was often the first sexual experience for the victim. Our findings were consistent with other reports of early and persistent hyper-eroticization of incest victims. SBI increased the likelihood of engaging in behaviors as an adult consistent with a co-existing or primary male-male sexual orientation, and SBI and CSA-AF had deleterious impacts on adult men's sexual adjustment with their adult partners.
