Feasibility and preliminary efficacy of training health workers in detecting Priority Mental Health Conditions among adolescents in rural South India

INTRODUCTION: Half of all mental disorders start during adolescence, before 14 years. In India, the current prevalence of mental disorders in 13–17 years age group was 7.3%. Many gaps persist in the mental healthcare delivery through the national mental health program, the low psychiatrist population ratio being one of them. Community health workers can play an essential role in providing mental healthcare in such resource-constrained settings. The World Health Organization mental health gap action program (WHO mhGAP) is a widely studied mental health tool that health workers can use to identify mental disorders. The study’s aim was to test the preliminary efficacy of training healthcare workers (HCWs) in identifying mental health conditions among adolescents using modified WHO mhGAP modules. METHODS: The feasibility study was carried out in two Primary Health Centers (PHCs) in rural Bengaluru. Study had two components: (1) training of HCWs on adolescent mental health and (2) detection of selected priority mental health conditions among adolescents by trained HCWs. HCWs were trained in five adolescent mental health conditions using a training manual and modified WHO mhGAP modules that excluded emergency presentations and management sections. Pre- and post-training assessments were carried out. A sample of 272 adolescents attending PHCs were assessed for any mental health condition by HCWs using mhGAP modules. A sub-sample of adolescents and all adolescents identified by HCWs with a mental health condition was interviewed by the investigator to validate the diagnosis. Qualitative interviews were carried out with participating HCWs to understand the acceptability of the intervention, acceptability, and barriers to training in identifying mental health conditions among adolescents RESULTS: A total of 23 HCWs underwent training. There was a significant increase in the mental health knowledge scores of HCWs post-training compared to baseline (p value <0.001). Out of 272 adolescents, 18 (6.8%) were detected to have any mental health condition by HCWs as per the modified WHO mhGAP modules. A sample of 72 adolescents consisting of all adolescents identified with a mental health condition by HCWs and a random sample of adolescents without any diagnosis were validated by the research investigator (AS). There was a good agreement between diagnosis by health workers and the research investigator with a Cohen’s Kappa of 0.88. Four themes emerged from the qualitative analysis. CONCLUSIONS: Training was effective in improving the knowledge of HCWs. There was a good agreement between trained HCWs and the investigator in detecting adolescent mental health conditions using modified mhGAP modules. The modified WHO mhGAP can thus be used by trained non-specialist HCWs to screen for adolescent mental health conditions in primary health centers.
