This study investigates the significant interaction between time and treatment on junior high school students' knowledge, attitude, refusal self-efficacy, and adaptive coping strategies, with age as a covariate. Substance use among adolescents is a pressing public health issue, necessitating effective school-based prevention programs.This research involved 390 students from Grades 7 to 10, who participated in the Lusog-Isip Kabataan Education (LIKE) Program.The treatment group consisted of 200 randomly selected students, while 190 students formed the wait-control group. A pretest-posttest design was employed using surveys to measure knowledge, attitudes, refusal self-efficacy, and coping behaviors. Data were analyzed using descriptive statistics and repeated measures ANOVA. The results indicated that the intervention did not produce significant within-subjects effects for most outcome measures, suggesting no substantial changes over time within individual students. However, significant between-subjects effects were observed for problem-solving and adaptive coping strategies among Grades 7 and 8, and for knowledge and cognitive reappraisal across the entire sample. These findings highlight the importance of demographic factors, particularly age, in shaping the effectiveness of interventions. The study recommends tailoring future interventions to account for age-related differences, implementing differentiated strategies to address varying cognitive and emotional maturity levels. Enhancing educational content and cognitive behavioral techniques can improve outcomes in knowledge and coping strategies. A comprehensive approach involving teachers, counselors, and parents is suggested to create a supportive environment for reinforcing learned skills. These insights can inform the design and implementation of more effective substance use prevention programs in school settings, ultimately reducing substance use among adolescents.
