<![CDATA[Premarital sexual behavior among adolescents is a public health concern that may lead to unintended pregnancy, sexually transmitted infections, and psychosocial consequences. Out-of-school adolescents in Situbondo Regency have limited access to comprehensive reproductive health education, highlighting the need for more interactive and effective educational media. This study aimed to analyze the effectiveness of the Reprocare Kit in increasing risk awareness and behavioral intentions regarding the risks of premarital sex among out-of-school adolescents. A quasi-experimental study with a one-group pretest-posttest design was conducted. A total of 80 out-of-school adolescents aged 15–19 years were selected using purposive sampling and received an intervention using the Reprocare Kit, consisting of an educational snakes-and-ladders game, playing cards, flipcharts, leaflets, and a guidebook. Data were analyzed using the Wilcoxon Signed Rank Test and N-Gain Score. The results demonstrated an increase in risk awareness, with an N-Gain score of 77.09%, and behavioral intention, with an N-Gain score of 78.76%, both categorized as effective. The Wilcoxon test indicated significant differences in scores before and after the intervention (p<0.05). In conclusion, the Reprocare Kit was effective in improving risk awareness and strengthening positive behavioral intentions toward preventing premarital sex among out-of-school adolescents, suggesting its potential as an interactive and applicable reproductive health education medium.]]>
