In the project proposed here, we aim at investigating the causal effects of job demands and job control on physical activity and well-being. This grant proposal is a follow-up application of the project „Warum Arbeit krank macht: Fehlende körperliche Aktivität in der Freizeit als Erklärung für negative Effekte von Arbeit auf Gesundheit“ (sign removed). In Project (sign removed) we developed a new theoretical model, the physical-activity-mediated Demand Control (pamDC) model (Häusser & Mojzisch, 2017) and tested its central hypothesis, that leisure time physical activity acts as a mechanism that partially mediates the effects of job characteristics on well-being. We conducted five studies using complementary methodological approaches (two ambulatory assessment studies, two experimental work place simulations, and one longitudinal field study). In a nutshell, these studies provide robust evidence for the validity of the propositions of the pamDC model. However, they also revealed the need to further specify and differentiate the model with respect to four regards. First, regarding the postulated effects of job control, the previous studies have, so far, not provided any clear evicende yet. A distinction between control regarding structure versus control regarding content of work might be fruitful. Second, job demands also need further specification, particularly a stronger emphasis on self-control demands. Third, a better consideration of the temporal dynamics, in which the effects postulated by the pamDC model unfold is needed to account for the psychological mechanisms underlying the model paths. Fourth, a specification of different facets of well-being is important, which also comprises physiological indicators of well-being. These objectives will be pursued in one ecological momentary assessment study and three experimental work place simulations. Besides specifying and differentiating different types of job demands and job control, the ecological momentary assessment study provides a first-time examination of the pamDC model with respect to physiological indicators of well-being (heart rate variability, electro-dermal activity) in the field. Moreover, the in situ measurement will provide valuable insights in the temporal dynamics of the effects described by the model. The three work place simulations will further help differentiating different types of job demands and job control and will provide an experimental mediation test. The project proposed here will contribute to a theoretical refinement of the pamDC model, enhancing its predictive power, and thereby increasing its theoretical and practical relevance.

在此处提出的项目中，我们旨在调查工作需求的因果关系以及工作控制对身体活动和福祉的影响。该赠款提议是该项目的后续应用。假设，休闲时间的体育活动是一种机制，它介导了工作特征对幸福感的影响，我们使用了五项研究（两项卧床评估研究，两个实验性的工作放置模拟，并在一项纵向领域研究中，这些研究都可以揭示pletiate the Persos of Persos of Pamdc of Pamdc的差异。尊重四个问题，首先是关于工作控制的效果，到目前为止，尚未提供任何明确的证据。关于结构与对工作内容的控制的控制与控制内容之间的区别可能是富有成果的。其次，工作需求还需要进一步的规范，尤其是对自我控制需求的强调。第三，更好地考虑了临时动力学，其中需要由PAMDC模型展开的效果来说明模型路径的心理机制。第四，对幸福感的不同方面的规范很重要，这也包括福祉的生理指标。这些目标将在一项生态瞬时评估研究和三个实验工作场所模拟中实现。除了指定和区分不同类型的工作需求和工作控制外，生态瞬时评估研究还针对该领域的幸福感（心率变异性，电 - der-dermal活动）进行了对PAMDC模型的首次检查。此外，原位测量将为模型描述的效果的临时动态提供有价值的见解。三个工作场所模拟将进一步帮助区分不同类型的工作需求和工作控制，并将提供实验调解测试。这里提出的项目将有助于对PAMDC模型的理论改进，增强其预测能力，从而提高其理论和实际相关性。
