As Elizabeth Heid Thompson of the Sutton Group and Ethel Klein advocate, ideally a campaign and its evaluation should be designed at the same time. Too often the evaluators are called in once the campaign has been set up. This allows them to establish together the important theory that underlies the campaign and the outcomes of interest, and for evaluators to inform the design process with formative research. Campaign designers and evaluators need planning tools that can assist them in this process and help them speak a common language. They need tools that respond to John Bare’s concern that “We need stronger theory-of-change models connecting the activities to the desired change.” While certainly not the only option available, logic models now perform this function in evaluations across many fields. This approach can be adapted to fit with public communication campaigns. For example, Figure 3 on the next page offers a template for a campaign logic model.12 Appendix B offers an example logic model based on the evaluation of the National Anti-Drug Youth Media Campaign.
