The document discusses several models of persuasion and behavior change communication. It summarizes McGuire's 6-step model of persuasion, Fishbein and Ajzen's Theory of Reasoned Action, and the Integrated Model of Behavior Change. The Integrated Model considers demographic, personality, and other individual difference variables that influence attitudes, norms, self-efficacy and ultimately intention and behavior. The model has been applied successfully in health campaigns around HIV/AIDS, smoking cessation, and other issues.
