This study focuses on the impact of digital technology on the physical and mental health of adolescents during a critical developmental phase. Objectives: The primary aim was to assess the effectiveness of a teaching program in raising awareness among adolescent students, in Bangalore, about the negative effects of excessive gadget use and strategies to mitigate these issues. Methods: A quantitative descriptive study was conducted using a one-group pretest-posttest quasi-experimental design. A convenience sample of 60 undergraduate adolescents participated. Data was collected through a pre-tested, semi-structured questionnaire administered both before and after the intervention. Results: The study findings revealed a 51.14% improvement in overall knowledge scores post-intervention. The calculated t-value was 28.41, which was statistically significant (P < 0.001). These results indicate a significant enhancement in participants awareness, demonstrating the effectiveness of the teaching program. Conclusion: The study highlights digital technology as a potential challenge, particularly for the physical and mental well-being of adolescents. Educating young people about the responsible use of electronic devices is vital to their holistic development. Efforts to promote such awareness contribute to nurturing well-rounded and health-conscious citizens.
