The link between burnout and depression remains unclear. In this study, we compared depressive symptoms in 46 burned-out workers, 46 outpatients experiencing a major depressive episode, and 453 burnout-free workers to test the distinctiveness of burnout as a clinical entity. Participants with burnout and major depressive episode reported similar, severe levels of overall depressive symptoms. The between-syndrome overlap was further verified for eight of the nine major depressive episode diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.). Our findings do not support the view hypothesizing that burnout and depression are separate entities and question the nosological added value of the burnout construct.

The “burnout syndrome” has been defined as a combination of emotional exhaustion, depersonalization, and reduced personal accomplishment caused by chronic occupational stress. Although there has been increasing medical interest in burnout over the last decades, it is argued in this paper that the syndrome cannot be elevated to the status of diagnostic category, based on (1) an analysis of the genesis of the burnout construct, (2) a review of the latest literature on burnout-depression overlap, (3) a questioning of the three-dimensional structure of the burnout syndrome, and (4) a critical examination of the notion that burnout is singularized by its job-related character. It turns out that the burnout construct is built on a fragile foundation, both from a clinical and a theoretical standpoint. The current state of science suggests that burnout is a form of depression rather than a differentiated type of pathology. The inclusion of burnout in future disorder classifications is therefore unwarranted. The focus of public health policies dedicated to the management of “burnout” should not be narrowed to the three definitional components of the syndrome but consider its depressive core.
