项目摘要
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.
在这里提出的项目中,我们的目的是调查工作要求和工作控制对身体活动和幸福感的因果关系。该赠款提案是“Warum Arbeit krank macht:Fehlende körperliche Aktivität in der Freizeit als Erklärung für negative Effekte von Arbeit auf Gesundouts”项目的后续申请(签名已删除)。在项目中,我们开发了一个新的理论模型,即体力活动介导的需求控制(pamDC)模型(Häusser & Mojzisch,2017),并测试了其核心假设,即休闲时间体力活动作为一种机制,部分介导了工作特征对幸福感的影响。我们进行了五项研究,使用互补的方法(两个门诊评估研究,两个实验性的工作场所模拟,和一个纵向现场研究)。简而言之,这些研究为pamDC模型的命题的有效性提供了强有力的证据。然而,它们也表明,需要进一步具体说明和区分四个方面的模式。首先,关于工作控制的假设影响,以前的研究,到目前为止,还没有提供任何明确的驱逐。区分对工作结构的控制和对工作内容的控制可能会有成效。其次,工作要求也需要进一步规范,特别是更加强调自我控制的要求。第三,更好地考虑时间动态,其中pamDC模型展开假设的效果需要考虑模型路径背后的心理机制。 第四,必须具体说明福祉的不同方面,其中还包括福祉的生理指标。这些目标将在一个生态瞬时评估研究和三个实验工作场所模拟。除了指定和区分不同类型的工作需求和工作控制,生态瞬时评估研究提供了一个第一时间检查的pamDC模型相对于健康的生理指标(心率变异性,皮肤电活动)在该领域。此外,现场测量将提供宝贵的见解,在时间动态的模型所描述的影响。三个工作场所模拟将进一步帮助区分不同类型的工作要求和工作控制,并将提供一个实验性的中介测试。这里提出的项目将有助于pamDC模型的理论完善,提高其预测能力,从而增加其理论和实践的相关性。
