Abstract
The structural validity of the Index of Organizational Reactions (IOR), a popular multi-faceted job satisfaction scale, was investigated through the use of confirmatory first and second-order factor analysis. Three plausible first-order factor models for the IOR were tested on a stratified random sample of 445 employees of a large financial institution. Through the application of a variety of covariance structure fit indices, it was found that an eight-factor oblique structure, which coincides with the eight facets of job satisfaction assumed to underlie the IOR, is the most appropriate factor model, thus supporting the structural validity of the IOR. Second-order confirmatory factor analysis revealed that two higher-order factors, corresponding to People in the work environment, and Material Aspects of the work experience, underlie the eight first-order factors. The scoring procedure for two "macrosubscales", based on the second-order factors, and suggestions for their use in applied settings were provided.
