Background: Academic stress is a significant psychological burden among adolescents and has been linked to adverse mental health outcomes. Increasing academic competition, parental expectations, and examination pressure contribute to stress levels among school-going students. Objective: To assess the level of academic stress and its association with mental health status among adolescents. Methods: A descriptive cross-sectional survey was conducted among 120 adolescents studying in selected secondary schools. Participants were selected using simple random sampling. Data were collected using a structured Academic Stress Scale and a standardized Mental Health Assessment Questionnaire. Descriptive statistics (mean, standard deviation, frequency, percentage) and inferential statistics (Pearson correlation and chi-square test) were used for analysis. Results: The findings revealed that 52% of adolescents experienced moderate academic stress, while 28% reported high stress levels. Regarding mental health status, 46% demonstrated mild psychological distress, and 22% showed moderate distress. A significant positive correlation (r = 0.62, p < 0.01) was found between academic stress and poor mental health outcomes. Conclusion: Academic stress significantly influences adolescent mental health. Early identification and implementation of stress management interventions in schools are recommended to promote psychological well-being.
