Title JCQ scale reliability and responsiveness to changes in manufacturing process
Bibliographic information Feb. 2008, Vol.51, No.2, p.138-147. 53 ref.
Abstract The job content questionnaire (JCQ) was administered to automobile manufacturing workers in two surveys, taken five years apart. Between the two interviews, the company introduced substantial changes in production technology in some production areas. The aims of this study were to describe the impact of these changes on self-reported psychosocial exposures and to examine the reliability of the JCQ scales, taking into account possible changes in job assignment. The study population included 790 subjects at the first and 519 at the second survey, of whom 387 participated in both. The introduction of more automated technology produced an overall increase in job control but did not decrease psychological demand. The reliability of the control scale was low overall but increased to an acceptable level among workers who had not changed job. The demand scale had high reliability only among workers whose physical ergonomic exposures were similar on both survey occasions.
