Based on Job Demands-Resources (JD-R), Conservation of Resources (COR) and self-regulation theories integration, this study investigated the association between role ambiguity and emotional exhaustion among 191 Romanian dentists, as well as the chain mediating role of cognitive crafting and three personal resources (resilience, optimism, and self-efficacy). Three conceptual models which included, separately, the three personal resources were proposed. PROCESS macros were used to verify the hypotheses related to the testing of the path mediation models. The results indicated that role ambiguity was directly and positively associated with dentists' burnout. More importantly, the sequential indirect effect of role ambiguity on burnout via mediators in chains (cognitive crafting and resilience for the first model; cognitive crafting and optimism for the second model; cognitive crafting and self-efficacy for the third model) was significant. The findings provide a direction for dentists' health intervention because it reveals how the negative impact of role ambiguity on emotional exhaustion increasing can be buffered by the cumulative effect of cognitive crafting and different personal resources, as a result of their chain reinforcement.
基于工作要求-资源（JD-R）、资源保存（COR）和自我调节理论的整合，本研究调查了 191 名罗马尼亚牙医角色模糊与情绪耗竭之间的关系，以及认知塑造和三种个人资源（韧性、乐观和自我效能）的链式中介作用。提出了三个包含这三种个人资源的概念模型。使用 PROCESS 宏来验证与测试路径中介模型相关的假设。结果表明，角色模糊与牙医的倦怠直接正相关。更重要的是，角色模糊对倦怠的序列间接效应通过中介在链条中（第一个模型中的认知塑造和韧性；第二个模型中的认知塑造和乐观；第三个模型中的认知塑造和自我效能）是显著的。这些发现为牙医的健康干预提供了一个方向，因为它揭示了角色模糊对情绪耗竭的负面影响如何通过认知塑造和不同个人资源的累积效应来缓冲，从而产生连锁强化。
