In addition to the insights provided by the transtheoretical model, the AIDS Community Demonstration Projects intervention was based upon three other models and theories of behavior change: the Health Belief Model, the Theory of Reasoned Action, and Social Cognitive Theory. Based on these theories, a core set of factors were identified and targeted in the intervention in order to encourage behavior change. Some of these factors included:
- Attitudes
- Perceived Norms
- Perceived Risk
- Self-Efficacy
The ACDP developed a model that showed how these and additional factors were linked to each other and to changes in behavior. This model guided the development of the intervention materials and the evaluation of the intervention.
These theories provided insights on how the intervention should be delivered. The Theory of Reasoned Action suggests that one should focus intervention messages on specific behaviors (e.g., condom use for sex with a main or steady partner). In addition, Social Cognitive Theory highlights the importance of peer modeling and social reinforcement of behaviors in human learning and behavior change. This theory suggested that peers could be particularly effective in delivering the intervention.
