Psychosocial working conditions and self-reported health in a representative sample of wage-earners: a test of the different hypotheses of the Demand-Control-Support-Model

Purpose. This paper presents an in-depth examination of the demand-control-support-model (DCS-model). Each hypothesis of the DCS-model is tested: the main effects of job demands, job autonomy, task variation and social support; the additive effects of job strain, active learning and iso-strain; and the interactive buffer-effects of job autonomy, task variation and support on job demands. Methods. Data from a representative cross-sectional sample of 11,099 male and female wage-earners are investigated using log linear methods. The outcome measures are self-reported persistent fatigue, musculoskeletal complaints and emotional well-being. Results.There is some support for each of the hypotheses. Quantitative job demands and superior support have the strongest effects. The job autonomy and buffer hypotheses are only partially supported. Conclusions. The strong effects of job demands, support, job strain and active learning are suggesting that a policy aimed at improving psychosocial working conditions should focus on a bearable level of job demands and the quality of social relationships at work
