The work environment, stress and well-being.

Abstract

Background: Much recent work extending the field of job characteristics to include positive aspects of work makes the implicit assumption that the absence of negative work characteristics is equivalent to the presence of positive work characteristics.

Aims: To consider the effect sizes seen at different ends of job characteristic dimensions and to compare the impact of the presence and absence of job characteristics in association with mental health and well-being outcomes.

Methods: Data from 8755 workers were analysed to compare the impacts of the presence or absence of job characteristics (job demand, extrinsic effort and social support) in associations with both positive (job satisfaction) and negative (work-related stress) outcome measures.

Results: Comparable presence and absence impacts were apparent for extrinsic effort in association with work-related stress. However, in the association between job demand and work-related stress, the presence of high levels of job demand had a significantly greater impact than the absence of high levels of job demand; while in the association between social support and job satisfaction, the absence of high levels of social support had a significantly greater impact than the presence of high levels of social support.

Conclusions: It is not always appropriate to assume that the absence of negative aspects of the work environment is equivalent to the presence of positive aspects.
