There is increased recognition that incorporating a social norms approach provides insights for understanding corporal punishment and/or discipline (CPD). This review seeks to explore how the literature analyses social norms and CPD in low- and middle-income countries (LMICs). We searched eight electronic databases, Google Scholar, Google and institutional websites, including articles in LMICs which examined social norms and CPD perpetrated by family members or teachers. Data was extracted, assessed for quality and analyzed according to key themes. Of 21,708 articles from academic databases and 92 from other sources, 37 studies were included. We observed heterogeneity in study design, and in the definition and measurement of social norms. In the majority of studies, social norms supporting CPD were either harmful or, at times, protective. The review also finds that gender, age, power hierarchies and changes such as conflict, migration and modernization may influence norms on CPD. CPD interventions should be evaluated over longer periods and with consideration to the continuum of violence between homes and schools. Future research on CPD should (1) theorize and define social norms more clearly; (2) examine both harmful and protective norms linked to CPD; (3) explicitly examine perpetration of violence across the home-school continuum.
