The job demands-resources model (JD-R model; Bakker & Demerouti, 2014) is well established in occupational research, and the proposed processes it posits have been replicated numerous times. Thus, the JD-R model provides an excellent framework for explaining the occupational well-being of beginning teachers-an occupation associated with particularly high levels of strain and consequently, high attrition rates. However, the model's assumptions have to date mostly been tested piecewise, and seldom on the basis of longitudinal models. With a series of longitudinal autoregressive SEM models (N = 1,700) we tested all assumptions of the JD-R model simultaneously in one model with an applied focus on beginning teachers. We assessed self-reports of beginning teachers at three time waves: at the beginning and end (one and a half to two years later) of their preservice period, and again, one year later. Results revealed significant direct effects of resources (self-efficacy) on engagement, of demands (classroom disturbances) on strain (emotional exhaustion), and a significant reverse path of engagement on self-efficacy. Additionally, the results showed two moderation effects: Self-efficacy buffered the demands-strain relationship, while self-efficacy also predicted engagement, especially when disturbances were high. Thus, self-efficacy in classroom management plays an important role in the teachers' stress development process, as it will, in case of high classroom disturbances, not only buffer the strain-enhancing effects, but also boost engagement. Commitment was predicted directly by emotional exhaustion and engagement, but indirectly only by self-efficacy (via engagement). Thus, we provide strong empirical support for the JD-R model.

工作要求-资源模型(JD-R 模型;Bakker 和 Demerouti,2014)在职业研究中得到了很好的建立,并且已经多次复制了它提出的过程。因此,JD-R 模型为解释新手教师的职业幸福感提供了一个极好的框架,新手教师这个职业与特别高水平的压力有关,因此离职率也很高。然而,迄今为止,该模型的假设大多是分阶段测试的,很少基于纵向模型。我们使用一系列纵向自回归 SEM 模型(N=1700),在一个应用于新手教师的模型中同时测试了 JD-R 模型的所有假设。我们在三个时间点评估了新手教师的自我报告:在他们职前阶段的开始和结束(一到两年后),以及一年后。结果表明,资源(自我效能感)对投入有显著的直接影响,需求(课堂干扰)对压力(情绪耗竭)有显著的直接影响,而投入对自我效能感有显著的反向影响。此外,结果还显示了两个调节作用:自我效能感缓冲了需求-压力关系,而自我效能感也预测了投入,尤其是在干扰较高的情况下。因此,课堂管理中的自我效能感在教师的压力发展过程中起着重要的作用,因为在课堂干扰较高的情况下,它不仅能缓冲压力增强的影响,还能提高投入。承诺直接由情绪耗竭和投入预测,但仅通过自我效能感(通过投入)间接预测。因此,我们为 JD-R 模型提供了强有力的实证支持。
