Abstract
The Swachh Bharat Mission undertaken by the Government of India (GoI) has been successful in accomplishing this objective within a short period thereby catalyzing governance following Sustainable Development Goals (SDGs). It is the responsibility of any democratic nation to ensure that its citizens have universal access to adequate and equitable sanitation. The key approach adapted to igniting a change in sanitation behavior rather than constructing toilets. An effort has been made in the study to affirm that even the marginalized sections of the society residing in tribal communities of West Bengal and Chhattisgarh have benefitted from this Government of India Mission and derived the required benefits. There is enough literature available to support the justification that civil participation holds the key for successful implementation of CLTS thereby making the communities open defecation free (ODF). It is therefore imperative to understand the behavioral transformation that takes place during the CLTS implementation. A hybrid model has been proposed in the study making use of the theory of reasoned action (TRA) and theory of planned behavior (TPB) to understand the pre-adoption and post-adoption behavior of residents. In present study, used model was empirically tested for several hypotheses. The finding reflects towards subjective norms and facilitating conditions as major determinants that ensure the continuation of intention for CLTS. They play a pivotal role in improving the health and hygiene conditions in the region and thus decrease the risk of spread of epidemic diseases.
