<![CDATA[Background: Adolescence is a critical period in individual development, marked by increased vulnerability to various risk behaviors, including those categorized under the Triad of Adolescent Reproductive Health (sexuality, HIV/AIDS, drug abuse). Low self-efficacy is one of the key factors influencing adolescents’ tendency to engage in or poorly cope with these risks. Objective: This study aims to develop a health coaching intervention module based on the Health Belief Model as an effort to enhance adolescents’ self-efficacy in preventing risks associated with the Adolescent Reproductive Health Triad (sexuality, HIV/AIDS, and drug abuse). Methods: The research method employed is Research and Development (R&D), using a modified Borg and Gall model approach. The study involved 100 adolescents aged 15–18 years, selected through a quota sampling technique. Before its use in data collection, the module underwent expert validation and a pilot testing phase. Results: The results of the module development indicate that the module is feasible in terms of content, presentation, and practicality. The intervention using this module was effective in enhancing adolescents’ self-efficacy, as evidenced by a significant increase in self-efficacy scores following the intervention. Conclusion: This module is expected to serve as an alternative promotive-preventive intervention in efforts to prevent risks associated with the Adolescent Reproductive Health Triad among adolescents. This module can be integrated into school programs or adolescent health promotion activities as a strategic effort to enhance knowledge, self-efficacy, and healthy behaviors in preventing the risks of preventing reproductive and behavioral health risks. This program is expected to enhance adolescents' self-efficacy in preventing reproductive health problems.]]>
