Crossover sexual offenses. Heil P1, Ahlmeyer S, Simons D. Abstract Crossover sexual offenses are defined as those in which victims are from multiple age, gender, and relationship categories. This study investigates admissions of crossover sexual offending from sex offenders participating in treatment who received polygraph testing. For 223 incarcerated and 266 paroled sexual offenders, sexual offenses were recorded from criminal history records and admissions during treatment coupled with polygraph testing. The majority of incarcerated offenders admitted to sexually assaulting both children and adults from multiple relationship types. In addition, there was a substantial increase in offenders admitting to sexually assaulting victims from both genders. In a group of incarcerated offenders who sexually assaulted children, the majority of offenders admitted to sexually assaulting both relatives and nonrelatives, and there was a substantial increase in the offenders admitting to assaulting both male and female children. Although similar trends were observed for the sample of parolees, the rates were far less dramatic. Parolees appeared to have greater levels of denial, had participated in fewer treatment sessions, and perceived greater supervision restrictions as a result of admitting additional offenses. These findings support previous research indicating that many sexual offenders do not exclusively offend against a preferred victim type. Multiple Paraphilic Diagnoses among Sex Offenders Gene G. Abel, MD; Judith V. Becker, PhD; Jerry Cunningham-Rathner, BA; Mary Mittelman, DrPH; and Joanne-L. Rouleau, PhD The psychiatric literature suggests that paraphiliacs can be expected to partic- ipate in only one type of deviant sexual behavior. Using self-reports gathered with assured confidentiality from 561 nonincarcerated paraphiliacs, we discovered that most paraphiliacs have had significant experience with as many as ten different types of deviant sexual behavior without regard, in many cases, to gender, age, and familial relationship of the victim. The relevance of these findings to our un- derstanding of paraphiliacs and their treatment is discussed. Sex crimes are a major social problem. portant research.
