This paper presents information on re-developing an outcome evaluation for a state-funded program providing service coordination utilizing wraparound to youth with severe emotional disturbance (SED) and their families. Originally funded by the Robert Wood Johnson Foundation, the Kentucky IMPACT program has existed statewide since 1990. Changing data needs and limitations of the original evaluation required revamping the program's data collection system. The new evaluation uses the extant knowledge base to improve: (1) design, (2) measures, and (3) utility. A pre-post design with multiple follow-ups provides the framework for data collection. An ecological framework provides a conceptual structure for selecting measures focusing on both the service recipients and their environment. Data collection via a personal digital assistant (PDA) ensures utility of the data for both consumers and researchers. Issues ranging from conceptualization to implementation of the project as well as lessons learned are discussed. (Contains 1 table and 1 figure.)
