A confirmatory investigation of a job demands-resources model was conducted with alternative methods, in a sample of 15,633 working adults aggregated from various economic sectors. The proposed model is in line with job demands-resources theory and assumes two psychological processes at work which are collectively coined "the dual process." The first process, the energetic, presents that job demands lead to ill-health outcomes due to burnout. The second process, the motivational, indicates that job resources lead to organizational commitment due to work engagement. Structural equation modelling analyses were implemented with a categorical estimator. Mediation analyses of each of the processes included bootstrapped indirect effects and kappa-squared values to apply qualitative labels to effect sizes. The relationship between job resources and organizational commitment was mediated by engagement with a large effect. The relationship between job demands and ill-health was mediated by burnout with a medium effect. The implications of the results for theory and practice were discussed.
我们采用替代方法，对来自不同经济部门的15633名在职成年人样本进行了一项工作需求-资源模型的验证性调查。所提出的模型符合工作需求-资源理论，并假设存在两个共同构成“双重过程”的心理过程在起作用。第一个过程是精力方面的，表明工作需求会因倦怠导致健康问题。第二个过程是动机方面的，表明工作资源会因工作投入导致组织承诺。我们使用分类估计器进行了结构方程建模分析。每个过程的中介分析包括自抽样间接效应和卡方值，以便对效应大小应用定性标签。工作资源与组织承诺之间的关系通过投入产生了很大的中介作用。工作需求与健康问题之间的关系通过倦怠产生了中等程度的中介作用。我们还讨论了研究结果对理论和实践的启示。
