Objective: Depression and burnout are two psychopathological labels that have been subject to an extensive
discussion over the last decades. The crucial question is whether they can be seen as conceptually
equal or as two distinct syndromes. One argument for the distinction is that depression impacts on the
whole life of a suffering person whereas burnout is restricted to the job context. Depression has been
shown to be affected by life stress. The more stressful life events a person experiences, the more he or
she is susceptible for developing a depression. As there is the widespread but controversial opinion that
burnout is a prodromal syndrome of depression, the present study examined whether the number of
stressful life events is also associated with an increased risk for burnout.
Methods: N = 755 healthy participants and N = 397 depressed patients completed the Maslach Burnout
Inventory (MBI), the Beck Depression Inventory (BDI II) and reported the extent of experienced life stress.
Results: A significantly closer relation between depression and life stress than between burnout and life
stress was found in the healthy (z = 3.01, p = .003) as well as in the depressed sample (z = 3.41, p = .001).
This finding was supported in both samples by means of a path analytic approach where the associations
between life stress, burnout, and depression were controlled for possible mediator and moderator effects,
also considering the influence of age.
Conclusion: By considering the influence of life stress it could be demonstrated that depression and
burnout are not identical although they share substantial phenotypic variance (r = .46–.61). Most important,
the trivariate associations are the same in a representative employee sample and in an inpatient
clinical sample suggesting the same underlying mechanisms covering the whole range from normal
behavior to psychopathology. However, only longitudinal data can show if burnout necessarily turns into
depression with the consequence that the burnout – life stress association approaches the depression –
life stress association over time.
