目的临床研究评估量表（CRAI）由92个项目组成，主要评估受训者在临床研究不同方面的自信心。完成冗长的CRAI是耗时的，对受访者来说是一个相当大的负担，但CRAI为评估研究培训计划提供了有用的数据。本研究的目的是开发一个缩短版本的CRAI，并测试其有效性和reliability. Methodtrainee在临床研究学位和职业发展计划在匹兹堡大学的临床研究教育研究所完成了92项CRAI之间2007年和2012年，包容性。作者进行了，第一，探索性因素分析的训练数据集（2007-2010年），以减少项目的数量，然后，验证性因素分析的测试数据集（2011-2012年），以测试的心理测量特性的缩短version.ResultsOf 546名学员，394（72%）提供了研究数据。探索性因素分析揭示了六个不同的因素，验证性因素分析确定了两个项目的最高负荷每个因素，共12个项目。Cronbach α的六个新的因素范围从0.80到0.94。12项CRAI中的因素与92项CRAI中的因素密切相关;相关性范围为0.82至0.96（P <0.001 each）.ConclusionsThe 12-item CRAI更快，负担更轻，但保留了原始CRAI的强大心理测量特性。
PurposeThe 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.MethodTrainees 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.ResultsOf 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).ConclusionsThe 12-item CRAI is faster and less burdensome to complete but retains the strong psychometric properties of the original CRAI.
