Process Evaluation: Linking HP-DP Programs and Impact
All programs need to achieve a high level of process implementation, or delivery of program components with fidelity, to have an opportunity to produce salient changes among populations at risk. Excellent examples of the methods and utility of a process evaluation applied to programs of national scope were described by several researchers: Stone National Heart, Lung, and Blood Institute, 1994), “Process Evaluation in the Multi-Center Child and Adolescent Trial for Cardiovascular Disease (CATCH); Baranowski and Stables (National Cancer Institute, 5-a-Day, 2000), “Learning What Works and How: Process Evaluations of the 5-a-Day Projects”; and Windsor, Whiteside, Solomon, et al. (Robert Wood Johnson Foundation, Smoke Free Families-National Program Office, 2000), “A Process Evaluation Model for Patient Education Programs for Pregnant Smokers.” In 1999, the CDC developed an Evaluation Framework. Steckler and Linnan (2003) completed one of the first books on the subject, Process Evaluation for Public Health Interventions and Research.
