The authors administered the Structured Clinical Interview for DSM-III-
R to 260 patients with principal diagnoses of depressive disorders.
Approximately two-thirds of these patients were given at least one
additional concurrent axis I disorder. The most common comorbid diagnoses
were anxiety disorders. The depressive disorders preceded the anxiety
disorders in most patients. The authors not only point out the scientific
and clinical implications of psychiatric comorbidity in view of the
patterns of comorbidity found in this and previous studies but also discuss
issues in comorbidity research.
