Viewing time measures and sexual interest: another piece of the puzzle

Abstract

The present study compared a viewing time (VT) measure with the Sexual Deviance Card Sort (Laws et al., 2000 Laws, D. R., Hanson, R. K., Osborn, C. A. and Greenbaum, P. E. 2000. Classification of child molesters by plethysmographic assessment of sexual arousal and a self-report measure of sexual preference. Journal of Interpersonal Violence, 15: 1297–1312. [Crossref], [Web of Science ®] , [Google Scholar]) and past sexual behaviour. Twenty-six adult males who committed a contact sexual offence (19 of whom had child victims and seven with adult victims) each completed the self-report card sort and viewed 640 slides of nude and clothed males and females, ages 5, 9, 13 years and adult. The offenders were unaware that their viewing time was being recorded. VT allowed for greater consistent classification of sexual interest: for gender preference, 79% for individuals with child victims, 86% for individuals with adult victims; for age preference, 84% for individuals with child victims, and 57% for individuals with adult victims. Results demonstrated that a combination of nude and clothed computer-modified imagery can provide accurate sexual interest classification.
