Association between psychosocial job characteristics and insomnia: an investigation using two relevant job stress models-the demand-control-support (DCS) model and the effort-reward imbalance (ERI) model

The ERI and DCS models describe the adverse psychosocial job characteristics related to insomnia. Simultaneously employing these two models is more useful than employing a single model to identify workers at risk of insomnia. The conceptual framework derived from the job stress models assists in defining preventive measures for insomnia in workers.
