| Abstract | Adolescent pregnancy rates in Phetchaburi Province, Thailand, persistently exceed the national average. Despite the Adolescent Pregnancy Prevention Act B.E. 2559 (2016), evidence-based prevention models suited to the local sociocultural context remain scarce. This study identified key predictors of pregnancy prevention behavior among in-school adolescents and developed a structured prevention model. A sequential mixed-methods design was conducted in Mueang District, Phetchaburi Province. In Phase 1, 308 adolescents aged 15–19 years were recruited through multi-stage random sampling. A validated questionnaire (Cronbach’s α = 0.87) measured sexual health literacy, self-efficacy, attitudes toward pregnancy prevention, perceived social support, and prevention behavior, analyzed using multiple regression. In Phase 2, four focus group discussions and two brainstorming sessions with 45 key informants informed model development. The regression model explained 41.4% of variance in pregnancy prevention behavior (R² = 0.414; F(4,303) = 53.47, p < 0.001). Self-efficacy was the strongest predictor (β = 0.42), followed by sexual health literacy (β = 0.31), attitude (β = 0.23), and perceived social support (β = 0.18). These findings guided development of the KAS Model — integrating sexual health Knowledge, self-efficacy (Ability), and pregnancy prevention behavior (Self-management) — comprising 12 structured activities, with strong content validity (CVI = 0.91). The KAS Model provides a practical, replicable framework for reducing unintended adolescent pregnancy. Utilizing community health volunteers and digital platforms such as the LINE application, the model is designed for integration into school health programs and primary care settings across comparable Thai provinces. |
