The participants were all imprisoned in a treatment center for compulsive sex offenders and all had histories of repetitive and compulsive sex offenses against adults. Data were collected regarding each participant's three most recent offenses. Offenders completed a structured clinical interview and the Alcohol Expectancy Questionnaire-III (Adult), a self-administered true-false questionnaire. Results support previous findings and indicated that the incidence of alcohol use and alcohol dependence in sex offenders exceeds that expected in a normal population. More than 61 percent of the participants had been drinking prior to every offense. More than 45 percent met diagnostic criteria for alcohol dependence. In addition, alcohol expectancies did not differ from that of the normative sample of the 1980 study conducted by Brown and others. Moreover, drinking at the time of the offense was not significantly related to violence or premeditation. Findings indicated that alcohol did not cause the men to rape, to be violent in the rapes, or to premeditate rape and that the exact relationship between rape and alcohol use or alcohol dependence in these men continues to be unclear. 52 references
