To prospectively investigate the association between Effort-Reward Imbalance (ERI) and over-commitment and the scores of the burnout dimensions over a 4 years follow-up period considering potential confounders. Data stemmed from CoLaus|PsyCoLaus, a population-based cohort study including 575 participants (mean age 55 years, 50% men). Participants completed the Maslach Burnout Inventory-General Survey, ERI and over-commitment questionnaires at baseline (T1) and after a 4 years follow-up (T2), and provided demographic, behavioral, psychiatric, personality and social support information through self-reported questionnaires and semi-structured interviews. Serially adjusted linear regression models were used. ERI and over-commitment were not associated longitudinally with any of the burnout dimensions when controlling for confounders. One standard deviation increases in the scores of exhaustion, cynicism and professional efficacy were associated with one standard deviation increase in the scores of the same burnout dimensions longitudinally, and these associations were independent of the effects of ERI and over-commitment. Future studies should re-examine the effect of ERI and over-commitment on workers' burnout, considering the effects of confounders.
前瞻性研究努力-回报失衡（ERI）和过度投入与倦怠维度评分之间的关系，考虑潜在的混杂因素，随访时间为 4 年。数据来自 CoLaus|PsyCoLaus，这是一项基于人群的队列研究，包括 575 名参与者（平均年龄 55 岁，50%为男性）。参与者在基线（T1）和 4 年后随访（T2）时完成了 Maslach 倦怠量表-一般调查、ERI 和过度投入问卷，并通过自我报告问卷和半结构化访谈提供了人口统计学、行为、精神科、人格和社会支持信息。使用连续调整的线性回归模型。在控制混杂因素后，ERI 和过度投入与倦怠维度的任何一个维度都没有纵向关联。倦怠维度中，疲惫、玩世不恭和职业效能的评分每增加一个标准差，与同一倦怠维度的评分纵向增加一个标准差相关，这些关联独立于 ERI 和过度投入的影响。未来的研究应该重新检查 ERI 和过度投入对工人倦怠的影响，同时考虑混杂因素的影响。
