The Mediation Chain Effect of Cognitive Crafting and Personal Resources on the Relationship between Role Ambiguity and Dentists' Emotional Exhaustion.

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.
