Social and Behavioural Change Communication (SBCC) is a strategic approach to influencing and transforming social norms, individual behaviours, and community practices through tailored communication interventions. Rooted in the understanding that behaviour is shaped by a complex interplay of knowledge, attitudes, social norms, and environmental factors, SBCC moves beyond mere information dissemination. It integrates behavioral science, communication theory, and participatory methods to promote sustainable changes that improve human development outcomes. Unlike traditional mass communication, which often focuses on raising awareness, SBCC seeks to engage individuals and communities actively, enabling them to internalize messages and adopt positive behaviors while challenging harmful practices. The conceptual foundation of SBCC lies in its multidimensional approach. It recognizes that behaviour change is not instantaneous; it is a gradual process influenced by awareness, knowledge, attitudes, self-efficacy, social support, and enabling environments. SBCC strategies typically involve formative research to identify the barriers and facilitators of desired behaviors, segmentation of target audiences, development of tailored messages, and selection of appropriate communication channels. These channels range from mass media campaigns, interpersonal communication, community mobilization, participatory theatre, and digital platforms to alternative media, all of which work in synergy to reinforce messages and create enabling conditions for change. SBCC has been widely applied in the domain of public health, education, gender equality, and environmental sustainability, demonstrating measurable impacts on attitudes, behaviors, and community engagement.
