Although each of the sites is unique, RTI has developed a framework for the evaluation that can accommodate site variation (Figure 1). The framework first isolates inputs as the key factors necessary to implement MFS-IP programming at each site; these include such things as ACF funding, technical assistance, and federal grant requirements. Inputs also include the partnerships grantees are able to form and existing resources external to the site that, in combination with site specific resources, yield a comprehensive set of services and programs available to the program participants (throughputs). The resulting outputs are the number of clients (both the incarcerated individuals and their partners) served by the program, the dosage of services received by program participants, systems-level change affected by the program, and sustainability strategies implemented. The measurement of the changes in knowledge and behaviors (outcomes) for participants and their children is an important factor in the evaluation framework. A variety of key intermediate and long-term outcomes are measured in the evaluation. Finally, as illustrated in the framework, community and individual participant characteristics influence the throughputs, outputs, and outcomes.
