An empirical exploration of a conceptual model for community-based health-promotion

Community-based approaches to health promotion and disease prevention are often based on underlying theoretical models of behavior change, but evaluations of these programs have not attempted to assess empirically the validity of these models. This article uses data from the Henry J. Kaiser Family Foundation Community Health Promotion Grants Program (CHPGP) evaluation to examine a conceptual model which guided the program evaluation. The model posits relationships among six theoretical constructs: community activation, program activity, norms, environment, role models, and health behaviors. Correlational analyses using two waves of survey data were used to examine whether the hypothesized relationships were actually present. Positive cross-sectional associations between the constructs at each point in time were found but the associations between changes in the constructs over time were weak. The stability of these cross-sectional patterns suggests that there may be forces leading communities to have an underlying "consistency" with respect to community norms, the environment, health behaviors and perhaps other community characteristics. If so, effective community-based programs may need to target a wide range of community characteristics rather than to focus narrowly on a single dimension.
