Sibling incest offenders

Abstract

Sibling incest is the least investigated but probably the most common form of incest. This study describes a predominantly Caucasian, middle-income sample of sibling incest offenders from primarily intact families. Demographics, behavioral dysfunction, psychiatric diagnoses, history of victimization, family characteristics, and abuse characteristics are presented. Findings included that 92% of the offenders had a history of being physically abused, whereas only 8% had a history of sexual victimization. Issues of parental denial and minimization and intergenerational transmission of abusive patterns are discussed. Sibling incest demands further attention from clinicians and researchers.
