Using a Random-Effects Model to Test Differing Conceptualizations of Multidimensional Constructs
研究质疑了以往将心理构念维度间关系视为固定效应的假设，提出用随机效应模型反映个体对多维构念的感知差异，并以薪酬满意度问卷为例验证了该模型的有效性。
Previous work investigating the dimensionality of psychological constructs has assumed a fixed-effects model, in which one true correlation describes the relationship between two given dimensions. We challenge this assumption by showing how a random-effects model may aid in representing individual perceptions of multidimensional constructs. Using the Pay Satisfaction Questionnaire (PSQ), we demonstrate that the relationships that individuals hold between the (purported) dimensions of the PSQ are predictable by cognitive complexity, pay level satisfaction, pay level, and interactions; we also show how between-dimension variation assists in establishing criterion-related validity.
