The purpose of this investigation was to empirically evaluate a sexual
assault prevention program. Of the 360 female college students who pa
rticipated in the investigation. 181 students were in the treatment gr
oup and 165 students were in the control group. Although the program w
as not effective in decreasing the incidence of sexual assault for wom
en with a sexual assault history, it was effective in decreasing the i
ncidence of sexual assault for women without a sexual assault history.
The program also led to a decrease in dating behaviors found to be as
sociated with acquaintance rape and an increase in knowledge about sex
ual assault for the treatment group. The implications of these results
for future preventive efforts are discussed.
