Empirical findings indicate that many adult sexual offenders experienced sexual abuse during childhood. It has been suggested that characteristics of offenders' sexual perpetrating behaviors may resemble their own victimization experiences, although there has been minimal empirical investigation in this area. The purpose of the present study was to provide preliminary data on the relationship between childhood sexual abuse and characteristics of sexual offending behavior. A sample of adult male sexual offenders with histories of sexual abuse completed the Sexual Victimization Survey as well as a measure on their sexual offenses. Such characteristics as the nature of sexual activities, duration and frequency of experiences, and age and relationship of participants were examined. Results showed trends in the hypothesized direction and revealed a variety of similarities between childhood sexual abuse and adult sexual perpetration. Findings of this exploratory study suggest the importance of addressing the nature of victimization in the treatment of sexually abused boys and offenders with histories of sexual abuse.  相似文献

Fear of victimization may have consequences for subjective well-being. I develop and test a model linking fear of victimization to subjective health. I hypothesize that two processes link fear to subjective health-psychological and behavioral. Specifically, I hypothesize that fear of victimization increases psychological distress, and fear decreases outdoor physical activity, especially walking. High levels of psychological distress and low levels of walking, in turn, are associated with poor self-reported health. I find empirical support for the hypothesized processes in a representative national sample of 2031 adults aged 18 to 90 interviewed by telephone in 1990. The negative association between fear and health is explained largely by psychological distress and walking. However, a significant direct effect remains. I conclude with suggestions for future research linking crime and health, focusing on the need for collecting information on community disorganization. Community context is likely the ultimate exogenous variable-the one that sets in motion the destructive cycle of fear, distress, inactivity, and poor health described here.  相似文献

Community-based delinquency prevention programs, designed to work with youth and families before they become involved with the official court process, are relatively rare. Likewise, few studies have been published concerninge valuative research on such programs. This article reviews some background on program concepts, describes the operations of the Oakland County Probate Court Youth Assistance casework services program, and reports the results of a comprehensive program evaluation project. The findings suggest that prevention programming is one effective strategy to aid in reducing the likelihood of more costly court interventions. Recommendations for program development are offered.  相似文献
