Background: Consumption of tobacco all over the world is considered to create morbidity and mortality that could be potentially preventable. Tobacco is said to be the major cause for non-communicable disease all over the world. Mortality because of NCDs responsible for about 63%. Total 80% of the deaths related to tobacco occur in the Low- and Middle-Income Countries throughout the world. Aim: This protocol will aid in conduct of research to assess and compare the efficacy of Multi theory Model and Modified Multi theory model as against Transtheoretical model Methods: The research will be carried out in a primary health care facility. The study design is three arm parallel cluster randomized interventional trial and cluster sampling method has been selected. The sample size has been calculated to 240 i.e 80 in each group. The Study will be conducted in primary health centre of the university for conducting community-based projects. The personnel at the main health centre will create the allotment sequence, register candidates, and allocate people to interventions Participant Identification Form, Fagerstrom Test for Nicotine Dependence, Smoking Abstinence Scale, and urine cotinine level will be used to collect data. In- person interviews will be conducted by the researcher for assessing the data. Following the completion of the trainings, post-test data was obtained by handling all data collecting instruments, including the Fagerstrom Test for Nicotine Dependence, the Smoking Abstinence Scale, and urine cotinine level. Participant Identification Form: the form, which was prepared by the researcher in line with the related literature, included 16 questions. Expected Outcome: On overcoming the limitations of transtheoretical model by conducting theory comparison and multiple-behavior research can prove to be a better approach for smoking cessation to the community.
