Background: Suicide has become a major public health concern among adolescents, with a rising trend observed both globally and in India. It is recognized as the second leading cause of death among individuals aged 15–29 years, primarily attributed to academic pressures, family expectations, psychological distress, and the ongoing stigma surrounding mental health problems. Aim of the Study: The study aimed to evaluate the effectiveness of a structured teaching program in improving knowledge regarding suicide prevention among adolescents. Methodology: A quantitative quasi-experimental one-group pre-test and post-test design was adopted among 60 adolescents studying in a selected Government Higher Secondary School at Pullichapallam. A structured questionnaire on demographic characteristics and suicide prevention knowledge was administered before and after the intervention. Data were analysed using descriptive and inferential statistics, including paired t-test and chi-square test. Results: The findings revealed a significant improvement in knowledge levels regarding suicide prevention following the educational intervention. Inadequate knowledge reduced from 23% before the teaching session to 2% after the intervention, while adequate knowledge increased from 33% to 68%. Mean post-test scores were significantly higher compared to pre-test scores (p < 0.001). Conclusion: The structured teaching program was found to be highly effective in enhancing adolescents’ knowledge of suicide prevention. Incorporating such school-based mental health education can help promote awareness, reduce stigma, and strengthen preventive behaviours among youth.
