ABSTRACT

The physical activity-mediated Demand-Control model (Häusser, J. A., & Mojzisch, A. (2017). The physical activity-mediated Demand–Control (pamDC) model: Linking work characteristics, leisure time physical activity, and well-being. Work & Stress, 31(3), 209–232. doi:10.1080/02678373.2017.1303759) posits that leisure-time physical activity (LTPA) is an important variable mediating the effects of job characteristics on well-being. Building on this model, we hypothesise that day-specific job demands and job control predict LTPA after work (via self-regulation and self-determination). LTPA after work, in turn, is predicted to be positively related to evening well-being. We tested these hypotheses by conducting a 14-day ambulatory assessment study. A sample of 207 employees wore an accelerometer to monitor physical activity and answered, three times a day, questionnaires addressing job characteristics, self-regulatory capacity, self-determination, and well-being. Results show that day-specific job demands were negatively related to LTPA and different indicators of evening well-being. We also found evidence for the mediation of the relationship between day-specific job demands and evening well-being via LTPA after work. However, contrary to our predictions, job control was not related to LTPA on a daily basis. These findings help to advance theory and, in particular, to understand the importance of LTPA for employee well-being.

摘要

身体活动介导的需求控制模型 (Häusser, JA, & Mojzisch, A. (2017)。身体活动介导的需求控制 (pamDC) 模型：将工作特征、休闲时间身体活动和幸福感联系起来。工作与压力, 31(3), 209–232。doi:10.1080/02678373.2017.1303759) 认为休闲时间体力活动 (LTPA) 是调节工作特征对幸福感影响的重要变量。在此模型的基础上，我们假设特定日期的工作需求和工作控制可以预测下班后的 LTPA（通过自我调节和自我决定）。反过来，预计下班后的 LTPA 与晚上的幸福感正相关。我们通过进行为期 14 天的动态评估研究来检验这些假设。样本中有 207 名员工佩戴加速度计来监测身体活动，并每天 3 次回答有关工作特征、自我调节能力、自我决定和幸福感的问卷。结果表明，特定日期的工作需求与 LTPA 和晚上幸福感的不同指标呈负相关。我们还发现了通过下班后 LTPA 调节特定工作日工作需求和晚上幸福感之间关系的证据。然而，与我们的预测相反，工作控制与每天的 LTPA 无关。这些发现有助于推进理论，特别是了解 LTPA 对员工福祉的重要性。
