Disaster and mental health preparedness are inseparable domains highlighted during all the major disasters in India. To build Disaster-Mental health Preparedness (Disaster MHP), one has to understand the existing strategies, systemic efforts, and ground-level implementation. In this scoping review, we have analyzed the mental health preparedness efforts during major disasters in India. We followed the Peters MDJ et al framework for scoping review named ‘Guidance for conducting systematic scoping reviews. This included the searching relevant articles on PubMed and google Scholar, and concept-context of the review. The review identified major efforts taken during ten disasters in past 40 years and mapping of the potential areas for development of sustainable efforts towards Disaster MHP. This is the first systematic scoping review from India that provides insight into strength and sustainability of disaster mental health preparedness in India. The mapping of the review focuses on the models emerged from Bhopal, Odisha, Tamilnadu and NIMHANS for the future infrastructure, capacity building, and environment required for Disaster-MHP in India.
