The possible effects of social norms on individual behaviours, have been under discussion since the past three decades, but only recently it has been substantiated through evidence generation. Targeting social norms is important, because norms are frequently the drivers or barriers to behaviour change and secondly, it is believed that adoption of behaviours by an individual is influenced by the surrounding socio-cultural environment. Studies indicate that interventions targeting a change in social norm are most effective if implemented in an environment where messages are delivered through multiple channels, and those that target collectives[1].
Social norms, defined as either informal understanding or codified rules of behaviour considered acceptable in a group or society. Social norms rely on indirect methods of persuasion that provide accurate information about what people think or do without telling them what they should actually do. The social norms approach integrates a variety of concepts and phenomena that have been well documented in the social science literature such as:
· Pluralistic ignorance– individuals act differently from how they feel
· Self-serving bias like false consensus to justify problem behavior
· Cognitive dissonance– providing accurate information about norms
There is a growing demand for evidence-based programming for social norm change, and rigorous scientific base, but there is limited experience. The USAID funded SPRING project conducted a systematic review of peer reviewed articles highlighting the importance of promoting behaviour change both at social as well as individual level utilizing all possible contact points. Though it suggests that interpersonal communication is key, context and an enabling environment play a significant role in shaping behaviour. Additionally, the role of delivery science including management, supervision, and training processes is emphasized[2].
Recent social norms interventions have focused largely on changing harmful behaviours, such as gender-based violence, alcohol consumption and child marriage. Social norms related interventions are fundamental and equally effective for addressing various forms of malnutrition, especially both stunting and anaemia, in any community setting. Perceptions of risk, outcome expectations, and access to IFA are key factors in effective social norms messaging for anaemia prevention.
The RANI (Reduction in Anaemia through Normative Interventions) project in Odisha tackled these factors through delivering group participatory learning modules in the community, targeting descriptive (one’s perceptions about others’ behaviour) and injunctive norms (one’s perceptions of social expectations regarding the behaviour). By focusing on topics like IFA supplementation, dietary diversity and social/gender norms, RANI was able to increase the odds of taking iron supplements in the community[3].
