This study investigated the effects of autonomous and controlled motivations, and workload on perceived stress, health, and performance. Workload was also considered as a moderator of the effects of autonomous motivation on perceived health and performance and of controlled motivation on perceived stress. We conducted an empirical study using a sample of 654 firefighters. Consistent with our predictions, results showed positive effects of autonomous motivation and negative effects of workload and controlled motivation on perceived health and performance. They also revealed positive effects of controlled motivation and workload and negative effects of autonomous motivation on perceived stress. Moreover, workload moderated the relations between autonomous motivation and perceived health and performance, so that the positive relations between autonomous motivation and perceived health and performance were lower when workload was high. Finally, workload moderated the relation between controlled motivation and perceived stress so that the positive relation between controlled motivation and perceived stress was stronger when workload was high. Theoretical contributions and perspectives, as well as implications for practice, are discussed.
本研究调查了自主动机和控制动机以及工作量对感知压力、健康和绩效的影响。工作量也被视为自主动机对感知健康和绩效的影响以及控制动机对感知压力的影响的调节因素。我们使用了 654 名消防员的样本进行了实证研究。与我们的预测一致，结果表明自主动机对感知健康和绩效有积极影响，而工作量和控制动机对感知健康和绩效有负面影响。它们还揭示了控制动机和工作量对感知压力的积极影响，以及自主动机对感知压力的负面影响。此外，工作量调节了自主动机与感知健康和绩效之间的关系，因此当工作量较高时，自主动机与感知健康和绩效之间的正相关关系较低。最后，工作量调节了控制动机与感知压力之间的关系，因此当工作量较高时，控制动机与感知压力之间的正相关关系更强。讨论了理论贡献和观点，以及对实践的影响。
