Three groups of subjects (N = 95) consisting or rapists, child molesters, and a comparison group of violent offenders were examined with reference to history of alcohol abuse, history of drug abuse, intimacy deficits, and emotionally based coping strategies. No differences were found between the two groups of sex offenders on any of the measures examined. Sex offenders were found to be significantly older than the comparison group. When age was entered as a covariate sex offenders were found to have significantly more difficulties with alcohol use as measured by the Michigan Alcohol Screening Test (MAST) and were significantly more likely to use emotionally based coping strategies as measured by the Coping Inventory for Stressful Situations (CISS). No differences were found between any of the groups with reference to drug abuse as measured by the Drug Abuse Screening Test (DAST). Results are discussed in terms of Marshall's theory of intimacy deficits in sexual offenders.
