[Anxiety disorders comorbid with unipolar depression. Clinical diagnoses versus standardized diagnostic interview].
Anxiety disorders frequently co-occur with affective disorders. It is well-known that such comorbid anxiety disorders are more frequently diagnosed with standardized interviews than during the "daily routine." In 117 consecutive inpatients with major depression we assessed the frequency of DSM-IV anxiety disorders and compared it to the routine diagnoses of the discharge letters to analyze underlying principles of such diagnostic strategies. According to SCID-I (DSM-IV) 36 patients fulfilled criteria for a comorbid anxiety disorder, while this was only true for 17 patients according to discharge letters. Logistic regression revealed that clinically recognized cases had higher anxiety levels (higher diagnostic threshold). At the same time, in patients with higher depression scores anxiety syndromes tended not to be seen as separate disorders. This strategy is in line with "classic psychopathology," where severe depression (or melancholia) "included" anxiety symptoms. The borderline between depressive disorders and anxiety disorders is not as clear-cut as DSM-IV and ICD-10 try to indicate.
