Indirect Measures of Sexual Interest in Child Sex Offenders : A Multi - Method Approach

Although there is strong meta-analytical evidence that deviant sexual interest in children is a major risk factor for recidivism in child-sex offenders, the assessment of deviant sexual interest with self-report or phallometric measures is problematic. As an alternative approach for assessment, the Explicit and Implicit Sexual Interest Profile (EISIP) is introduced that features direct self-report and indirect latency-based measures (Implicit Association Tests and viewing time measures) of sexual interest in adults and children. The reliability and validity of the EISIP was investigated using a selected sample of child sex offenders (n = 38), offender (n = 37) as well as non-offender (n = 38) controls. Among the indirect measures, viewing time measures showed higher reliability, convergent, and criterion validity than the IATs. However, the IATs independently accounted for criterion variance in multivariate analyses. The combined indirect measures showed good discriminative validity between child-sex offenders and controls.
