Judgments of the potential benefits of rehabilitation research

A critical step in a project to develop a benefit-cost approach to evaluating proposed rehabilitation research has been to specify the potential benefits of such research in a reasonably systematic and comprehensive manner. The purposes of this study were: (1) to assess the contemporary relevance of 46 benefit factors yielded by a 1973 survey: (2) to acquire judgmental data to reduce these factors to fewer and more generic 2nd-order factors: (3) to compare 7 different rehabilitation role groups in terms of how the potential benefits of rehabilitation research are valued. "Hierarchical clustering" analyses of similarity judgments by 96 participants yielded 18 2nd-order benefit factors. A number of reliable differences were identified among the role groups regarding the value placed upon specific potential benefits of rehabilitation research.
