Abstract

Current approaches to job design and job stress, and their application in the context of new manufacturing technologies and practices, call for new widely applicable measures of job properties. In response to this need, Jackson, Wall, Martin and Davids (1993) described the development of new scales of timing control, method control, monitoring demand, problem-solving demand and production responsibility. This article provides further evidence concerning these measures, based on the responses of nearly 1700 employees from five separate samples. The evidence includes: investigation through confirmatory factor analysis of the applicability of the underlying five-factor measurement model on two new samples; improvement of the problem-solving demand scale; a test of the replicability of the measurement model by formal factorial invariance tests across four samples; additional information on scale reliability and construct validity; and normative data for a wide range of shopfloor and related jobs.
