Description

Measures of sexual interest in child sex offenders -

View that sexually deviant behaviours result from favouring these over accepted sexual activity - Assessing sexual interests is very difficult - Direct measures of sexual interest: rely on self report measures of deviant sexual preferences in questionnaires or card-sort procedures - > Validity jeopardized by impression management and deliberate faking - >> Issue with transparency in direct measures - personal info embarrassing, socially undesirable, illegal - Indirect measures of sexual interest: participants less aware of measurements/principle, expression of measured construct cannot be directly controlled? - > Rely on physiological measures of sexual arousal or response latency measures, PPG - >> Latency-based measures involve rating, sorting or detection tasks involving pictorial stimuli - >> Viewing time measures Current study: - Little research comparing reliability and criterion validity of different latency based measures of sexual interest - Research of this kind required to investigate to what extent latency-based measures could improve the assessment of sexual preference over and above direct measures - Introduce and validate Explicit and Implicit Sexual Interest Profile - > 4 direct self report measures, 3 IATs and 4 VT measures - Aim to investigate reliability and convergent validity of EISIP, explore to what extent the diff measures contributed to a discrimination between child sex offenders and controls - 38 child sex offenders, 75 controls including 37 offenders Measures: - Explicit Sexual Interest Questionnaire (ESIQ) two subscales assessing sexual behaviour and sexual fantasy, 5 items each - With 40 items, EISIP is highly economical and conceptually directly comparable with indirect measures - Indirect EISIP measures: - > Ps asked to 1-5 rate sexual attractiveness of target stimuli, viewing time recorded - > 3 diff IATs with object categories man-woman, girl-woman and boy-man - >> Had to assign pictures to man-boy / women-girl / boy-man - >> Press left for man or sexually unexciting, woman or sexually exciting - Used balanced inventory of desirable responding and screening scale for paedophillic interests Results: - Man-woman and girl-woman IATs showed near satisfactory reliability (a = .79) - All EISIP measures of homosexual interest in men indicated paedophillic preferences - Boy only sex offenders showed strongest interest in boys and hardly any interest in girls - Boy only sex offenders produced the highest VTs for men and boys - Sex offenders showed higher levels of general sexual interest

Discussion: - Provide first preliminary evidence that EISIP test battery is a reliable and valid measure of sexual interest - VT measures outperformed IATs Implications: - Economical computer based assessment tool to assess socially problematic and/or inappropriate sexual interest - Nonintrusive and ethically acceptable - EISIP may prove useful to assess sexual interest in context of criminal progress - Sex offender sample showed higher levels of deviant sexual interests and also socially acceptable sexual interests - May be useful in therapeutic context to confront denying sex offenders with their deviant sexual interest...
