*4.3. Burnout and QWL: Contribution to Productivity and Appropriate Salary as Mediators (Model 2)*

Considering model 2, the same set of effects are analyzed (cf. Tables 6–8), evaluating two mediators (i.e., contribution to productivity and appropriate salary). For the first dimension of burnout, i.e., emotional exhaustion, the total effect is −1.054325, which is the effect found if there are no mediators in the model. It is significant, with a z of −6.64. The direct effect for emotional exhaustion is -1.019637, which is still quite significant (z = −5.99), although slightly smaller than the total effect. The indirect effect of emotional exhaustion that passes through the contribution to productivity and appropriate salary is −0.0346888 and is not significant.

The proportion of the total effect mediated is −0.0346888/−1.054325, resulting in −0.0329014. The ratio of the indirect to direct effect is −0.0346888/−1.019637, equaling −0.0340207. The ratio of the total to direct effect corresponds to −1.054325/−1.019637, equaling −1.0340199. The proportion of the total effect that is mediated is almost −0.33, which is a respectable amount. The ratio of the indirect effect to direct effect is about −0.03, and the total effect is about −1.034 times the direct effect.

Concerning the second dimension of burnout, i.e., cynicism, its total effect is -1.011313, which is the effect found if there are no mediators in the model. It is significant, with a z of −6.30. The direct effect for cynicism is −0.9078191, which, while still significant (z = −5.29), is smaller than the total effect. The indirect effect of cynicism that passes through the contribution to productivity is −0.01034937 and is also not significant.

The proportion of the total effect mediated is −0.01034937/−1.011313, resulting in −0.0102335. The ratio of the indirect to direct effect is −0.01034937/−0.9078191, equaling −0.0114001. The ratio of the total to direct effect corresponds to −1.011313/−0.9078191, equaling −1.1140027. The proportion of the total effect that is mediated is almost −0.010, which is a small amount. The ratio of the indirect effect to direct effect is about -0.011, and the total effect is about −1.114 times the direct effect.

Regarding the third dimension of burnout, i.e., the feeling of low effectiveness, its total effect is −1.716576, which is the effect found if there are no mediators in the model. It is significant, with a z of −10.15. The direct effect for low effectiveness is −1.444998, which, while still significant (z = −8.13), is smaller than the total effect. The indirect effect of low effectiveness that passes through the contribution to productivity is −0.2715781, and it is also highly significant.

The proportion of the total effect mediated is −0.2715781/−1.716576, resulting in −0.1582091. The ratio of the indirect to direct effect is −0.2715781/−1.444998, equaling −0.1879435. The ratio of the total to direct effect corresponds to −1.716576/−1.444998, equaling −1.1879435. The proportion of the total effect that is mediated is almost −0.16, which is quite an important amount. The ratio of the indirect effect to direct effect is about −0.19, and the total effect is about −1.19 times the direct effect.
