Background: Mental Healthcare Act 2017 (MHCA) came into force on 29 May 2018. Goa State Mental Health Authority (GSMHA) notified the Mental Health Review Board on 8 February 2022, completing the important process of implementation of the act. The transition comes with challenges. Methods: A qualitative study was conducted with 18 practicing psychiatrists who had worked under Mental Health Act 1987 as well as MHCA 2017 through purposive sampling across Goa. Data was collected through individual interviews; analysis was done by Braune and Clarke’s framework of Thematic Analysis. Results: Eighteen psychiatrists participated: 4 private, 3 secondary and 11 from tertiary levels. The themes extracted were work during MHA 1987, transition, and after the implementation of MHCA 2017. Some participants reported difficulties, felt an increase in workload, and had negative emotions, while a few were neutral, indicating mixed perceptions. Conclusion: This study highlights the administrative struggles and moral dilemmas faced by psychiatrists in handling the new legislation. It’s imperative that the implementation of new act should be carried out with sufficient resource allocation and monitoring mechanisms.
