The purpose of the study was to examine the impact of self-efficacy in the prevention of sexually transmitted diseases (STD), knowledge of and susceptibility to STD, and the role of gender in sexual autonomy.


Data were collected from 267 college students using self-report questionnaires during the period from the first to the twentieth of June 2015. Data were analyzed using χ2 test, Fisher's exact test, t-test, Pearson correlation coefficients, simple and multiple regression techniques with the PASW/WIN 20.0 program. Mediation analysis was performed according to the Baron and Kenny method and Sobel test.


In male students, self-efficacy for STD prevention showed a full mediating effect in the relationship between STD susceptibility and sexual autonomy (β=-.08, p=.370). But in female students, it had a partial mediating effect (β=-.25, p=.001). And self-efficacy for STD prevention showed partial mediating effects in the relationship between knowledge of STD and sexual autonomy in the both male (β=.25, p=.005) and female students (β=.33, P<.001).


To enhance college students' sexual autonomy, it may be useful to build effective strategies enhancing students' knowledge about and susceptibility to STD and to develop a self-efficacy promotion program for college students.
