Mediation Analysis

In the final part of the study we conducted the mediation analysis, to understand the relationship between job satisfaction, job involvement and organizational commitment. We used bootstrapping, based on 5000 samples and the confidence interval of 95%.

We started with a model that contains just one relation between satisfaction and commitment (Figure 5A), then tested for full mediation (Figure 5B) and finally partial mediation as indicated in our proposed model (Figure 5C). The unstandardized, direct effect regression weights and the p-values obtained in these experiments are shown in Table 8. As the p-values show, all the connections in our three models are significant and that they remain so throughout the evolution of the model. Therefore, job involvement mediates the influence of satisfaction on organizational commitment, but this is a partial mediation and a major part of the effect of satisfaction on the organizational commitment is achieved directly.
