The risk for using child abuse images (CAI) is difficult to assess, especially as it mostly remains undetected by legal authorities. The present study investigates the association of aspects of sexual preference and dynamic risk factors with CAI only and mixed offending (CAI and child sexual abuse) over lifetime and within six months prior to assessment. A sample of 190 undetected, self-identified pedo- and/or hebephiles was investigated. Multinomial logistic regression analyses revealed that sexual preoccupation is of great importance, especially for recent CAI only and mixed offending, as well as lifetime mixed offending. Although inconclusive, a sexual preference for early-pubescent children seems to be of interest for recent and lifetime offending. A sexual preference for prepubescent children, additional paraphilias and sexualised coping have shown some, although no statistically meaningful association with lifetime offending. Gender preference, exclusivity of pedohebephilia and offence-supportive attitudes did not show any significant relation with offending behaviour.
