<![CDATA[Low reproductive health literacy and healthy behavior among Indonesian adolescents remains a major challenge in the digital era, especially amid the widespread circulation of invalid information. This study evaluates the effectiveness of a digital-based reproductive health education model in improving adolescents' literacy and healthy behavior, while also exploring students' needs, barriers, and expectations. A sequential explanatory design was used across two phases. Phase I used a quasi-experimental approach involving 100 junior and senior high school students in Bandung (50 intervention; 50 control). Literacy and behavior were measured before, after, and three months post-intervention using valid and reliable instruments (CVI 0.87; α>0.8). Phase II used focus group discussions with 8 adolescents and interviews with 8 stakeholders, which were analyzed thematically. Results showed a significant increase in reproductive health literacy in the intervention group (52.3±12.1 to 78.9±9.8; p<0.001) and in healthy behavior (+21.4%; p=0.003), with a large clinical effect (Cohen's d=1.15) that was sustained for three months. Perceived benefits, peer support, and curriculum integration were key success factors. Qualitative findings highlighted the need for relevant content, interactive features, ease of access, privacy protection, and online counseling services, while limited digital access and infrastructure remained barriers. In conclusion, digital-based reproductive health education is effective and well received by adolescents, and its national implementation requires curriculum integration, equitable digital access, support services, and multisectoral collaboration.]]>
