Background: This report describes the findings of the survey conducted by South African Depression and Anxiety Group (SADAG) in a cohort of disadvantaged South African adolescent scholars in which PHQ-9 teen version was modified and adapted (PHQ-9M) to improve the response rate. Method: PHQ-9M was administered to 2025 secondary students of 35 schools over 2 years in Gauteng Province, South Africa. Results: The mean age was 15.8 years. 23% of respondents scored 9 or above, 26.7% reported suicidal ideations in last month, 21.8% reported lifetime suicide attempts and 9.3% had severe functional impairment. PHQ-9M showed a fair internal consistency and face validity in this study. Conclusion: The PHQ-9M could be useful in conducting surveys in settings of low mental health literacy after further evaluation of its psychometric properties. The high rates of suicidal ideations, suicide attempts, and functional impairment in this population suggest the need for preventive interventions.
