The purpose of the present study was to examine the psychometric properties of the Organizational Justice Scale, developed by Colquitt (2001). This scale administered to a sample working in an industrial company in Khozestan province. The sample consisted of 355 employees selected by stratified random sampling method. The scale measures four dimensions of organizational justice including distributive justice, procedural justice, informational justice, and interpersonal justice. In the present study, validity of the scale was examined in two ways: Confirmatory factor analysis (CFA) and discriminative construct validity. CFA using AMOS, indicated that four-factor model fit with data better than one, two, and three factor models, and all items loaded on their factor, significantly. In addition, each factor was correlated with theoretically relevant variable. Specifically, distributive justice, procedural justice, informational justice, and interpersonal justice had significant correlations with instrumentality, group commitment, helping behavior, and collective esteem, respectively. Results of this study provide evidence supporting the validity of the organizational justice scale and its applicability in Iran.
