Construct Validity of Three Types of Organizational Citizenship behavior: An Illustration of the Direct Product Model with Refinements
改进了直接乘积模型，用于分析多特质多方法数据，并通过组织公民行为研究验证了三种构念的聚合效度和区分效度，发现不同评价者视角存在显著差异。
The direct product model is a new analysis tool for modeling multitrait-multimethod data. This model may avoid some of the problems associated with conventional analysis of multitrait-multimethod data by allowing for the possibility of multiplicative trait-method interactions. Based on the work of Browne (1984; 1990), we suggest several refinements in testing this model, including use of confirmatory procedures for testing model fit and implementation of a hierarchical approach to model comparisons. We provide an illustration of the refined direct product approach using a study of three types of organizational citizenship behavior. The results supply evidence for convergent and discriminant validity of the three constructs, and suggest that job incumbents, supervisors, and peers have significantly different perspectives of organizational citizenship behavior.
