PURPOSE: The original Clinical Research Appraisal Inventory (CRAI), which assesses the self-confidence of trainees in performing different aspects of clinical research, comprises 92 items. Completing the lengthy CRAI is time-consuming and represents a considerable burden to respondents, yet the CRAI provides useful data for evaluating research training programs. The purpose of this study is to develop a shortened version of the CRAI and to test its validity and reliability. METHOD: Trainees in clinical research degree and career development programs at the University of Pittsburgh's Institute for Clinical Research Education completed the 92-item CRAI between 2007 and 2012, inclusive. The authors conducted, first, exploratory factor analysis on a training dataset (2007-2010) to reduce the number of items and, then, confirmatory factor analyses on a testing dataset (2011-2012) to test the psychometric properties of the shortened version. RESULTS: Of 546 trainees, 394 (72%) provided study data. Exploratory factor analysis revealed six distinct factors, and confirmatory factor analysis identified the two items with the highest loadings per factor, for a total of 12 items. Cronbach alpha for the six new factors ranged from 0.80 to 0.94. Factors in the 12-item CRAI were strongly and significantly associated with factors in the 92-item CRAI; correlations ranged from 0.82 to0.96 (P < .001 for each). CONCLUSIONS: The 12-item CRAI is faster and less burdensome to complete but retains the strong psychometric properties of the original CRAI.
