In one of the most comprehensive theoretical model for health promotion intervention planning by Green and Kreuter (1999), the PRECEDE-PROCEED theoretical model, some of the determinants of behavior outlined include Predisposing factors, Enabling factors and Reinforcing factors. By moving progressively through nine phases this model offers comprehensive framework for planning a health promotion intervention. As mentioned earlier the PRECEDE-PROCEED model has nine phases, the first five are diagnostic: (1) social diagnosis of the self-determined needs, wants, resources, and barriers to them in the target community; (2) epidemiological diagnosis of the health problems; (3) behavioral and environmental diagnosis of the specific behaviors and environmental factors for the program to address; (4) educational and organizational diagnosis of the predisposing, enabling, and reinforcing conditions which immediately affect behavior; and (5) administrative and policy diagnosis of the resources needed and available in the organization, as well as the barriers and supports available in the organization and community.

The four remaining phases in PRECEDE-PROCEED are implementation and evaluation (process, impact, and outcome), with emphasis on using the latter to improve the former. Evaluation of the process begins as soon as implementation does, in order to detect problems early so they can be corrected. As implementation proceeds, the planner starts evaluating in the order in which program effects are expected. First, its immediate effects (impacts) are evaluated, in order to determine the extent to which the program needs modification. Finally, when enough time has passed--as specified in the objectives--the ultimate intended effects on morbidity, mortality, and quality of life are assessed. This kind of phased evaluation allows you to see what works and what does not.
