混合项目反应理论（IRT）模型已被用于评估被测结构的多维度性，并检测不同群体的不同反应风格。在这项研究中，混合版本的分级反应模型，调查的可扩展性和预测效度的职业发展背景下的尽责性量表（N = 9283）。一个四类的解决方案产生了最可解释的结果。班级的差异主要在于他们在完美主义和专注力分量表上的得分。结果表明，尽责性可能是定性不同的人，不同类别的人相比，拟合一维IRT模型的测试成绩的预测有效性提高。本研究对人格评估的启示进行了讨论。(C)2010年爱思唯尔公司All rights reserved.
Mixture item response theory (IRT) models have been used to assess multidimensionality of the construct being measured and to detect different response styles for different groups. In this study a mixture version of the graded response model was applied to investigate scalability and predictive validity for a Conscientiousness scale in a career development context (N = 9283). A four-class solution yielded the most interpretable results. The classes differed mainly with respect to their scores on the subscales Perfectionism and Concentration. Results showed that Conscientiousness may be qualitatively different for different groups of persons and that the predictive validity of the test scores improved for persons in different classes as compared to fitting a unidimensional IRT model. Implications of this study for personality assessment are discussed. (C) 2010 Elsevier Inc. All rights reserved.
