Inappropriate analysis of mortality in mental disorders

There are serious problems with this analysis of mortality in mental disorders. Walker et al. have very inappropriately generalized mortality estimates derived from their analysis of clinical samples (primarily tertiary treatment samples), which include high proportions of patients (often inpatients) with psychotic disorders, to cases of common mental disorders (primarily anxiety disorders and mood disorders) identified in population surveys (World Mental Health (WMH) surveys). The authors have thereby grossly exaggerated the population-level mortality due to mental disorders. Unfortunately this has been accepted uncritically by the reviewers, the editors, and many readers.
