This study evaluates the reliability of the 'rape index' as a technique in differentiating rapists from nonrapists by exposing inmates to sexual stimuli and measuring penile response.
Abstract
It presented 18 persons incarcerated on nonsexual-related offenses with visual and audio stimuli depicting mutually consenting intercourse, rape, and aggression. These stimuli were presented under two instructional sets: enhance arousal and suppress arousal. Reliability indices for the rape index were computed among various conditions of modality presentation, instructional set, and test-retest conditions. The overall reliability of the rape index was low. Implications of these findings for offender assessment and classification are discussed. Data tables and 12 references are supplied.
