This document discusses information, education, and communication (IEC) and its role in promoting behavioral changes. IEC aims to change or reinforce behaviors in a target audience regarding a specific problem within a set time. It draws from various fields like diffusion theory and social marketing. The goals of IEC include changing individual, family, and community health behaviors, motivating the adoption of healthy attitudes, and facilitating education and awareness creation. IEC programs are developed for various health initiatives and aim to produce IEC materials for mass media and interpersonal communication channels. Key approaches to IEC include interpersonal, group-based, and mass communication methods.
