Overview

Using the intervention functions of Behavior Change Wheel (BCW) and BCTs, we constructed an intervention program for college students' risky sexual behaviors by combining literature analysis, qualitative research, Delphi's expert correspondence, and pre-experiment (20 students in the test group and 20 students in the control group). Before the intervention (T0) and at the end of the intervention (12 weeks, T1), we measured students' psychosexual health, social support, and sexual self-efficacy using relevant scales to ensure the effectiveness of the intervention. By clarifying the influencing factors of college students' risky sexual behaviors, the proposed intervention program for college students' risky sexual behaviors can effectively reduce the incidence of college students' risky sexual behaviors, improve the level of college students' psychosexual health, increase the level of social support, improve the sense of sexual self-efficacy, improve the level of risk perception, enhance the ability of risky decision-making, reduce the risky behaviors, and reduce the occurrence of adverse outcomes, thus providing a reference and reference for the prevention and control of college students' risky sexual behaviors. This will provide reference for the prevention and control of risky sexual behaviors among college students.
