Prevention starts here: effectiveness of substance abuse prevention module among adolescent students in Bengaluru – a quasi experimental study

Abstract

Abstract Objectives This study aims to evaluate the effectiveness of a structured educational module on substance abuse prevention program among adolescents in enhancing their knowledge against substance abuse. Methods A quasi-experimental design was employed involving 120 students (mean age: 14.3±1.03 years, 59.2% boys) from two English medium schools. Participants were exposed to a structured module on substance abuse over a month. The study assessed changes in knowledge through pretest and post-test evaluations. Statistical analyses examined improvements in scores and the relationship between class of study and post-test knowledge scores. Results The intervention significantly improved students’ knowledge about substance abuse (p<0.001) across all measured domains, genders, and classes, with the exception of the 7th class. A positive correlation was found between the class of study and post-test scores (Rs=0.288, p<0.001), indicating that higher classes were associated with greater improvements in knowledge. These findings suggest that the training effectively increased awareness and understanding of substance abuse among participants. Conclusions The substance abuse prevention program successfully enhanced adolescents’ knowledge and equipped them with resilience and coping strategies, thus reducing their vulnerability to peer pressure and substance abuse. Despite the lack of significant improvement in the 7th class, the overall positive outcomes underscore the importance of implementing such educational interventions to foster healthy development and well-being among students. Further research is encouraged to explore the specific barriers to effectiveness in younger classes and to refine program content accordingly.
