Phase 1, social assessment and situational analysis, involves engaging the target population to identify general indicators of quality of life. Phase 2, epidemiological assessment, includes identifying specific health goals or problems that contribute to or interact with the social goals or problems identified in phase 1. Phase 3, behavioral and environmental assessment, involves identifying and prioritizing behavioral and environmental determinants of the specific health problems identified in phase 2. Phase 4, educational and ecological assessment, includes identifying and prioritizing predisposing, reinforcing and enabling factors that are related to the behavioral and environmental determinants. " Predisposing factors include a person's or population's knowledge, attitudes, beliefs, values and perceptions that facilitate or hinder motivation for change." Reinforcing factors are "the rewards received and the feedback the learner receives from others following adoption of a behavior." " Enabling factors are those skills, resources or barriers that can help or hinder the desired behavioral changes as well as environmental changes." Phase 5, intervention alignment and administrative and policy assessment, involves "intervention matching, mapping, and patching" to determine which program components and activities are needed to target the factors identified in the previous stages and determining whether or not the program has the policy, organizational and administrative capacity to do them. In phase 6, implementation occurs. Phase 7 includes process evaluation, phase 8 includes impact evaluation, and phase 9 includes outcome evaluation.
