Purpose: The purpose of this study was to evaluate the effects of a sexual violence counselor program on knowledge toward sexual violence, sexual autonomy and rape myths. Method: One group, pretest-posttest design was used. The program was delivered to thirty-three persons during 10 weeks for a total of 65 hours. Results: After the program, knowledge toward sexual violence increased significantly from 11.6 to 12.5(t=-2.10, p<.05), and sexual autonomy increased significantly from 50.6 to 53.7(t=-2.35, p<.05). After the program, rape myths decreased significantly from 42.4 to 29.0(t=7.80, p<.001). Conclusion: A sexual violence counselor program was effective to increase knowledge toward sexual violence and sexual autonomy and to diminish rape myths.
