CONSTRUCT-VALIDITY OF 3 TYPES OF ORGANIZATIONAL CITIZENSHIP BEHAVIOR - AN ILLUSTRATION OF THE DIRECT-PRODUCT MODEL WITH REFINEMENTS

The direct product model is a new analysis tool for modeling multitrai t-multimethod data. This model may avoid some of the problems associat ed with conventional analysis of multitrait-multimethod data by allowi ng for the possibility of multiplicative trait-method interactions. Ba sed on the work of Browne (1984; 1990), we suggest several refinements in testing this model, including use of confirmatory procedures for t esting model fit and implementation of a hierarchical approach to mode l comparisons. We provide an illustration of the refined direct produc t 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, sup ervisors, and peers have significantly different perspectives of organ izational citizenship behavior.
