Integration of Psycho-social Social Support and Mental Health Services in to National Disaster Management Guidelines India is vulnerable, in varying degrees, to a large number of natural as well as man-made disasters and also a high risk country for disasters due to expanding population, urbanization and industrialisation, development within high-risk zones, environmental degradation and climate changes. The creation of National Disaster Management Authority (NDMA) in 2005, as the apex body for disaster management, has brought out a paradigm shift in the area of disaster management. One of the important mandate of NDMA is to issue National Disaster Management Guidelines (NDMG) to the ministries/ departments to assist them to formulate their respective Disaster Management (DM) plans. In this direction NDMA has issued number of NDMG on different themes to provide basis of preparation of DM plans at different levels. There are policies & guidelines on Psycho-social Support and Mental Health Services (PSSMHS) in disasters at the international level in the form of Inter Agency Standing Committee guidelines (IASC) which advocates PSSMHS in disasters. In India there was no such policy which streamlines the Psycho-social Support and Mental Health Services in Disasters. During preparation of various National Disaster Management Guidelines, one remarkable factor noticed was the need for psycho-social care, subsequently preparation of NDMG on Medical Preparedness and Mass Causality Management brought out an overwhelming consensus to formulate a separate NDMG for PSSMHS. In order to translate the critical need for psycho-social care and support into guidelines, NDMA adopted a mission-mode approach for integrating PSSMHS in disaster response by involving participatory and multi step methodology to formulate NDMG on Psycho-social Support and Mental Health Services in Disasters.
