Applying job demands-resources theory, this quasiexperimental, three-wave study investigated whether work engagement can be increased via an eLearning intervention aiming to increase job crafting behavior. Furthermore, proposing a refinement to job demands-resources theory, that is, adding "a health enhancement process," this study also investigated whether through improvements in work engagement, the intervention would yield health-related benefits, utilizing an objective indicator of physical health (i.e., optimal functioning of autonomic nervous system activity indicated by increased heart rate variability [HRV]). The study was conducted among all the employees of a municipality (n = 69/experimental group, n = 45/control group), and the effects were assessed 2 weeks and 4 months after the intervention. Job crafting and work engagement were measured using an electronic questionnaire, and HRV using ambulatory monitoring period of two nights' sleep. Latent change score modeling revealed, as expected, that job crafting increased both immediately and delayed after the intervention. Furthermore, as hypothesized, the intervention increased work engagement via increased job crafting when measured immediately after the intervention, but there was no indirect delayed effect on work engagement. There were no indirect immediate or delayed effects on HRV. However, unexpectedly, HRV decreased among the control group after the intervention. Thus, an eLearning intervention based on the principles of job crafting is a promising tool to increase job crafting and consequently work engagement. Furthermore, the findings provide an initial indication that a job crafting eLearning intervention could have a buffering effect on autonomic nervous system activity and help to maintain its optimal functioning.

工作重塑电子学习干预能否促进工作重塑和工作投入，并增加心率变异性？测试健康增强过程。

这项准实验性三波研究应用工作需求资源理论，调查了是​​否可以通过旨在增加工作塑造行为的电子学习干预来提高工作投入度。此外，本研究提出对工作需求资源理论进行改进，即增加“健康增强过程”，并利用客观的身体健康指标，调查干预措施是否可以通过提高工作投入度产生与健康相关的益处。 （即，心率变异性 [HRV] 增加表明自主神经系统活动的最佳功能）。该研究在一个城市的所有雇员中进行（n = 69/实验组，n = 45/对照组），并在干预后2周和4个月评估效果。使用电子问卷来测量工作重塑和工作投入度，并使用两晚睡眠的动态监测来测量心率变异性。正如预期的那样，潜在变化评分模型显示，工作重塑在干预后既立即增加，又延迟增加。此外，正如假设的那样，在干预后立即测量时，干预通过增加工作重塑来提高工作投入度，但对工作投入度没有间接的延迟影响。对 HRV 没有间接、即时或延迟的影响。然而，出乎意料的是，干预后对照组的 HRV 下降了。因此，基于工作重塑原则的电子学习干预是提高工作重塑和工作投入度的有前途的工具。此外，研究结果初步表明，工作制定电子学习干预可能对自主神经系统活动产生缓冲作用，并有助于维持其最佳功能。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
