While there has been increasing tendency of juvenile sexual offenders, they have not been studied systematically in Korea. The purpose of this thesis is to understand psychosocial characteristics of juvenile sexual offenders. This purpose was done along with comparisons with juvenile nonsexual offenders. We used K-YSR(Korean-Youth Self Report), Revised UCLA loneliness Scale, Rape Myth Acceptance Scale, IRI(Interpersonal Reactivity Index), and Coping Using Sex Inventory. 15 juvenile sexual offenders and 26 juvenile nonsexual offenders were participated. We use student's -t test as statistical method. Juvenile sexual offenders showed lower empathy and used sex as coping strategy more frequently than juvenile nonsexual offenders. However, there were no significant differences in loneliness and rape myth acceptance . These were different with many previous other studies. Limits of this study are numbers of offenders are few and sexual offenders are in different conditions compared with nonsexual offenders. This thesis tried to say that the deficits and distortions of empathy, coping method, and loneliness were the results of devastating early parent-child relationship. But to do this we must have found the relationship of early attachment style and current deficits. This was left undone. We suggest the sex without empathic understand and as coping method under stressful situation are not like the sex with love. These are the result of not having been taken care of. Especially of empathic care from their parents. In this study we did not investigate the relationship between attach-menent style and sexual offending. This will be done in the following study.
