- Abstract
The measurement equivalence of 2 scales of the Job Descriptive Index (JDI; P. C. Smith, L. M. Kendall, & C. L. Hulin, 1969), the Supervisor Satisfaction scale and the Coworker Satisfaction scale, was examined across computerized and paper-and-pencil administrations. In this study, employees in 2 organizations (N = 1,777) were administered paper-and-pencil versions of the scales, and employees in a third organization (N = 509) were administered a computerized version. A newly developed item response theory (IRT) technique for examining differential test functioning (N. S. Raju, W. J. van der Linden, & P. F. Fleer, 1995) was used to examine measurement equivalence across media. Results support the measurement equivalence of the JDI Supervisor and Coworker scales across administration media. The implications of these findings for both practitioners and organizational researchers are discussed.
