The high incidence of risky sexual behavior among adolescents is caused by several factors, such as the environment and low selfcontrol. Adolescents living in former red-light districts are at higher risk of risky sexual behavior due to environmental factors and a lack of self-control. Therefore, appropriate psychoeducational media are needed to help improve adolescents' selfcontrol so that risky sexual behavior can be prevented. This study aims to determine the content validity of the ‘SCOUPER’ self-control psychoeducation module as a preventive measure against risky sexual behavior among adolescents in former red-light districts. This study used the Research and Development (R&D) method with a 3D model (Define, Design, and Develop). The define stage analyzed the needs of adolescents, the design stage developed the self-control psychoeducation module, and the develop stage included validity testing with rating scores by experts or validators. The data analysis used in this study was descriptive analysis with Aiken's V formula and validator input. The validity test results showed that the SCOUPER self-control psychoeducation module scored between 0.75 and 1,00 in the high – very high category. Based on the validity test results, the SCOUPER module can be concluded to be valid for use with some suggestions and improvements from the validator. The SCOUPER self-control psychoeducation module is valid in terms of content, construct, and language, and has the potential to be used as a preventive medium in preventing risky sexual behavior among adolescents, especially in former red-light districts.
