ABSTRACT: Study
assessed the dimensional structure of the Job Content Questionnaire’s (JCQ 2.0)
main scales in two different work contexts. We evaluated two surveys among
Brazilian workers, comprising 3084 health workers and 489 industrial workers.
An exploratory factor analysis with oblique Geomin rotation explored the model,
and subsequently, a confirmatory factor analysis assessed the factor structure
and possible modifications of the model. The internal consistency of JC scales
was assessed by using estimates of composite reliability and Cronbach’s alpha.
The structural model was confirmed, with a good fit in the two studies, despite
low factors’ loads for some items of “decision authority” and “psychological
job demands”. We concluded that the JCQ dimensional structure corresponded to
its theoretical framework in the two work contexts analyzed.
