BackgroundMental health issues are a major concern in rural India, but the lack of trained professionals limits access to care. In this pilot study, we evaluated the efficacy of a mental health assessment training program for Accredited Social Health Activists (ASHA) in rural Maharashtra, India.Aim and objectiveTo conduct a pilot study to evaluate the feasibility and potential efficacy of Mental Health Assessment Training by using the Global Mental Health Assessment Tool-Primary Care Marathi Android version (GMHAT/PC-M) on ASHA workers in the Wardha district to identify mental health problems.MethodsThe study enrolled 12 ASHA workers from two rural health centers in Maharashtra. The workers completed a pretest and then received training in mental health assessment using the GMHAT/PC Marathi Android version. Mental health knowledge and global mental health assessment tool checklist scale scores were assessed on day seven, month one, and month three after training.ResultsThe ASHA workers had a mean age of 42.2 years and a mean experience of 9.6 years. The majority were Hindus (50%), with the remaining workers being Buddhist. Of the 12 workers, only four had prior mental health training. Mental health knowledge and global mental health assessment tool checklist scale score significantly improved from the pretest to day seven (p<0.001), and the scores continued to improve at month one and month three with a 0.001 level of significance. At the end of the study, the mean mental health knowledge score was 15.2 (out of 20), and the mean global mental health assessment tool checklist scale score was 55.5 (out of 60).ConclusionOur pilot study demonstrated the effectiveness of a mental health assessment training program for ASHA workers in rural Maharashtra, India, using the GMHAT/PC Marathi Android version. The training program improved the mental health knowledge and GMHAT checklist scale of the ASHA workers, suggesting that such programs can help bridge the gap in mental health care in rural areas. Further studies with larger sample sizes and longer follow-up periods are needed to confirm the effectiveness of this training program.
