The study examines the factors contributing to adolescent school adjustment, focusing on the roles of social support, resilience, and positive affect. Using a cross-sectional design with 1397 high school students, the researchers analyzed the predictive relationships between teacher and peer support, resilience, positive affect, emotional engagement, school integration problems, and perceived academic performance. The results indicate that teacher and peer support, resilience, and positive affect indirectly predict perceived academic performance through emotional engagement and school integration problems. Specifically, emotional engagement negatively affects school integration problems, and resilience positively predicts positive affect. Teacher support also positively predicts emotional engagement, while peer support negatively predicts school integration problems. The study highlights the importance of teachers in fostering emotional engagement and the protective role of peer relations in school adaptation. The findings provide insights into the complex mechanisms underlying school adjustment and suggest the need for structured guidance programs and activities to enhance these factors.The study examines the factors contributing to adolescent school adjustment, focusing on the roles of social support, resilience, and positive affect.
