A cognitive-based indicator of deviant sexual interest: Concurrent validation of the Stroop task

ABSTRACT

One of the strongest predictors of sexual recidivism is sexual deviance Hanson, R. K., & Bussière, M. T. (1998). Predicting relapse: A meta-analysis of sexual offender recidivism studies. Journal of Consulting and Clinical Psychology, 66, 348–362. doi:10.1037/0022-006X.66.2.348]. Phallometric testing, the most commonly used method of assessing sexual deviance, has elicited methodological and ethical criticisms, while self-report is vulnerable to social desirability and poor insight. To overcome these limitations, researchers have utilised cognitive measures, including a modified Stroop task, to measure deviant sexual interests among sex offenders using victim selection as a comparison measure. However, the results have been inconclusive. The current study explored the validity of the modified Stroop task as a measure of deviant sexual interest among a non-offending sample of 570 females and 223 male participants, using self-report as the comparison measure. The results indicated a significant gender difference in concurrent validity; there was a significant relationship between self-reported deviance and deviant word Stroop performance for male but not for female respondents, suggesting the Stroop is a viable option for assessing sexual deviance among males. Implications of these findings are discussed relative to sexual recidivism risk assessment.
