| Abstract:
This paper describes the evaluation planning process and resulting evaluation design for CDC’s Colorectal Cancer Control Program (CRCCP), a public health program aimed to increase population-level screening rates and, subsequently, to reduce colorectal cancer incidence and mortality. Planning efforts involved the development of a conceptual program framework, articulation of a program logic model, assessment of existing data sources, and extensive discussions among evaluators, survey researchers, epidemiologists, clinicians, and qualitative researchers. A theory-based evaluation has been designed to assess program implementation, outcomes, and impact. The design involves quasi-experimental approaches, including the use of matched comparison sites. The complexity of the CRCCP program (e.g., multiple intervention strategies that vary by grantee) challenged evaluators to construct a rigorous design that will allow assessment of program effectiveness. Evaluation methods will include periodic cross-sectional population and provider surveys, surveys of grantees, a longitudinal qualitative case study, and analysis of BRFSS, NPCR, and SEER data.
