Women's self-efficacy and sexually transmitted disease preventive behaviors.

Knowledge of sexually transmitted disease (STD) prevention, perceived risk for STDs, and self-efficacy for STD prevention were investigated as predictors of behavioral risk for STDs in 308 female college students. Perceived risk and self-efficacy predicted 19% of behavioral risk for STD; knowledge was not a predictor. Self-efficacy was highest for communicating about STD prevention and lowest for refusing sexual intercourse. Interventions that enhance both women's self-efficacy to prevent STDs and accurate risk appraisal are likely to be more effective than those that emphasize only knowledge of prevention techniques.
