Grounding evidence-based approaches to cancer prevention in the community: a case study of mammography barriers in underserved African American women.

ABSTRACT

When community health planners select an evidence-based intervention that has been developed and tested in one situation and adapt it for use in a different situation or community, best practice suggests needs assessment and formative research in the new setting. Cancer prevention planners who are interested in adopting and adapting evidence-based approaches need to base their choices on a sound understanding of the health or behavioral risk problem in which they mean to intervene. This requires a balancing act of weighing community information against a broader perspective from the scientific literature and using the combination to identify and adapt an evidence-based intervention program that is likely to be effective in the new setting. This report is a case study of a community and organizational assessment conducted as a foundation for selecting and recommending adaptation of an evidence-based intervention for improving mammography appointment attendance. We used an inductive sequential exploratory mixed-methods design to inform this process. The process provides a model for formative research grounding evidence-based practice for cancer control planners. Future studies that incorporate findings from needs assessment into the adaptation of the selected intervention program may promote the effective dissemination of evidence-based programs.
