The purpose of this study was to evaluate the effects of a sex education program, which was based on the Health Belief Model, on knowledge related to sexually transmitted diseases and sexual autonomy among university students.

A non-equivalent control group, pretest-posttest design was used. The four session program was delivered to 18 students during 4 weeks; the control group consisted of 23 students. The theme of the first session was “sex, gender, and sexuality: all our concern”, “dangerous sex” for the second session, “safe sex” for the third session, and “right sex for you and me” for the fourth session.

At follow-up, the knowledge related to sexually transmitted diseases and sexual autonomy were significantly greater in the intervention group than in the control group.

A sex education program with several sessions within the theoretical frame of HBM was effective to improve knowledge related to sexually transmitted diseases and sexual autonomy. The results suggest the potential of a systematic sexual education program to teach healthy sex and to extend the program for other various populations.

The purpose of the study was to test the effectiveness of an 8 session intervention program to prevent sexually transmitted diseases (STDs) among at-risk prostitutes.

An experimental research design was employed. Subjects were 59 prostitutes (29 in the control group and 30 in the experimental group) who agreed to participate in this study. An STD Prevention Framework derived from Cox's Interaction Model of Client Health Behavior guided the overall intervention and the components. The intervention had 8 sessions with STD-prevention strategies and was led by Public Health Nurses. Analysis included change scores, χ²-test, and t-test.

The results revealed significant increase in feelings and skills of condom use, peer belief on condom use, condom use practice, and satisfaction with service at public health centers (PHC) on STDs knowledge and skills in the experimental group. However, newly contracted STDs were not significant statistically between groups.

The 8 session STDs prevention program showed a effect on emotions, skills and behaviors of condom use even withthe limitation of methodological rigors because of subject-specific conditions. In the future, a capacity-building model based on collaborating networks among community-based organizations will be needed to develop in effective STDs prevention.
