This study was designed to (a) examine the dimensionality of rape attitudes; (b) explore the relationships between perceptions of rape and background characteristics of rapists, police, female rape crisis counselors, and citizens; and (c) determine how these groups might differ with regard to rape attitudes. Data were collected from 1,448 Ss from the aforementioned groups using measures of Ss' attitudes toward and knowledge of rape, the Attitudes Toward Women Scale, and a personal data form. Results show that the groups were similar in their structures of rape attitudes. As predicted, sex, race, and marital status were the most important characteristics for predicting rape attitudes; within the respondent groups, however, other characteristics were found to be important. Significant differences were also found among the groups in their perceptions of rape. The counselors differed from the police, citizens, and rapists in their views of rape, while citizens and police were most similar. No differences were found between the police and rapists on half of the attitudinal dimensions. Implications of the results are discussed in terms of attitudes toward rape.
