[Depression and anxiety--a study for validating subtypes of depression].
Psychopathological analysis of the patterns of symptoms in 176 depressive in-patients disclosed in 73.3% of all patients the presence of anxiety symptoms: of these, 38.6% merely had diffuse anxiety, whereas 34.7% showed either additionally or alone specific anxiety symptoms such as phobias and panic attacks. Similar to the results obtained by dividing the patients into an "endogenous" and "neurotic" group, namely, that there was no difference between the subtypes in respect of triggering the depressive episodes by life events, or in respect of the suicide rate 30 months after discharge and in respect of a chronic course developing during the 2 years following the discharge, there was likewise no difference with regard to these criteria if the patients were subdivided into depressive patients without anxiety and those with anxiety symptoms. However, a subdivision of the depressive patients with anxiety symptoms into a group having only free-floating anxiety and a group with specific anxiety symptoms, resulted in a clear association with these criteria: If a phobia or panic attacks were present, triggering by life events was far more frequent than if there was only free-floating was more often chronic in the first group, but there was no difference in suicidality. The results indicate that it will be necessary to provide for a more differentiated classification of anxiety symptoms before deciding in clinical routine what steps to take wherever depression and anxiety symptoms are present side by side. The same applies to treatment studies.
