Response Bias on Self-Report Measures of Sexual Fantasies Among Sexual Offenders.

The impact of sexual fantasies in future risk and treatment response among sexual offenders has long been known. However, as we develop objective self-report measures of sexual fantasies, response bias is becoming an increasing concern. In examining a sample of institutionalized sex offenders, the present study suggests that offenders' responses on these measures are prone to response bias, the bias does not negate their associations with other self-report measures of sexual deviance, and relationship of their sexual fantasies does not appear to relate to actual behavioral indications.
