Associations between overcommitment, effort–reward imbalance and mental health: findings from a longitudinal study

Purpose The effort–reward imbalance (ERI) model includes extrinsic and intrinsic aspects of work stress. The single components, ERI and overcommitment (OC), are known to be associated with mental health. The aim of this study was to test whether OC is a mediator of the association between ERI and mental health.
