ObjectiveThe objective of this review is to synthesise evidence regarding the different types of behaviour change interventions used by community health workers and the predictors of success/failure of these interventions.IntroductionBehaviour Change Communication (BCC) serves as a key pathway for delivering messages for modifying risky behaviours such as unsafe sex, malnutrition, tobacco use and drinking, consuming unhealthy diet and leading a sedentary lifestyle. Behaviour Change Communication has been successfully applied in various settings, conditions, participants and providers. In Low- and Middle-Income Countries (LMICs), the delivery of BCC is achieved through Community Health Workers (CHWs) due to limitation of resources. There are evidences which indicate success and potential for upscaling of delivering BCCs via CHWs. However, summarized evidence regarding the healthcare domains where CHW delivered BCC is effective, the means of delivering these interventions, and success or failure of these interventions in adults is unavailable.Inclusion CriteriaLiterature freely available, in English language, without any limits on time of publication will be included for reviewing. This review will consider all randomized controlled trials, field trials, community-based studies and implementation researches using BCC as mode of intervention, carried out in all healthcare domains, aimed at adults.MethodsMEDLINE, ScienceDirect, ERIC, JSTOR, DOAJ will be searched for identifying relevant studies. OATD will be searched for identifying appropriate theses and dissertations. After initial screening of the titles and subsequently abstracts, data will be extracted and tabulated in a custom-made template. All the reviewers will analyse the extracted data and present the results as a statistical description and inductively coded analysed content.
