A Validation Study of KASI in Differentiating Pedophiliac Sex Offenders out of Non-Pedophiliac Child Molesters

Abstract

This study searched for the validity evidences of KASI(Korean Assessment of Sexual Interest; Lee, 2011) in discriminating pedophiliac sex offenders from non-pedophiliac child molesters. Pedophiliac subjects who participated in this study were 7 patients of a psychiatric unit and 5 inmates of a prison diagnosed as pedophile based on DSM-Ⅳ. 31 non-pedophiliac child molesters participated in a control group. Relative preference toward stimuli among 4 groups of pictures(pictures of girls, boys, women, and men) were measured by within-subject standard scores of viewing time by KASI. Repeated measures of ANOVA revealed that pedophiliac sex offenders had relatively longer viewing time onto the pictures of girls. Also, it was found that rule-of-thirds principle of KASI had significant consistency with the membership decision of criterion groups made by the DSM-Ⅳ.
