Notes: c: associations of extrinsic effort, reward and overcommitment with emotional exhaustion; a: associations of extrinsic effort, reward and overcommitment with PsyCap; b: association between PsyCap and emotional exhaustion after controlling for the predictor variables; c’: associations of extrinsic effort, reward and overcommitment with emotional exhaustion after adding PsyCap as mediator; a × b: the product of a and b; BCa 95% CI: the bias-corrected and accelerated 95% confidence interval age, marital status, education and weekly work time are covariates; * significant at the 0.05 level (2-tailed); ** significant at the 0.01 level (2-tailed).
