Summative evaluation involved testing whether the SI groups had a greater change in CVD nutrition knowledge and behavior (as measured by self-report) 24 hour diet recalls, and serum cholesterol) from baseline to an eight week post-test, and through a five month maintenance period. The generalization phase of the research tested a revised version of the program in a non-classroom setting with Head Start families, and intervened at the community level to modify the food selection and preparation practices of organizations (such as soup kitchens, food banks, and homeless shelters) that provide food to low-income/low-literate groups. As the concluding aspect of the study, the feasibility was explored of disseminating the nutrition program and education modules to local and national groups serving low-literate populations.
