ABSTRACT
Forty six patients (23 in-family and 23 out-family child sexual offenders) diagnosed with pedophilia participated in this study. For each patient, computerized objective data, obtained from the doctors, nurses, psychologists, and prosecutors involved, and the hospital information system, were collected. Immediately after the authors collected data that included any personal identifying information, it was replaced by random numbers to prevent bias and to protect privacy. Statistical analysis was performed using SPSS version 20.0 for MS Windows. Comparative items on demographic characteristics were evaluated by a paired t test and chi-square test. Out-family child sexual offenders were younger, assaulted younger victims, and possessed a higher sexual recidivism rate than in-family sexual offenders did (P<0.05). The four scales of Minnesota Multiphasic Personality Inventory showed a significant difference between in-family and out-family child sexual offenders. There was no statistically significant difference in the victim's gender and the incidence of comorbid psychiatric disease between in-family and out-family child sexual offenders.
