The current study extends the development and evaluation of an existing and previously evaluated sexual assault risk reduction program with a self-defense component for college women (N = 300). The program protocol was revised to address psychological barriers to responding assertively to risky dating situations, and a placebo-control group was utilized rather than a wait-list control group. Relative to the placebo-control group, the program was effective in increasing levels of self-protective behaviors, self-efficacy in resisting against potential attackers, and use of assertive sexual communication over a 4-month interim. Results also suggested reduction of incidence of rape among program participants over the 2-month follow-up. Implications for future development and evaluation of sexual assault risk reduction programming are presented.
