Identification of the Endogenous Depressive Syndrome Based on the Symptoms and the Characteristics of the Course

Abstract

Summary: Using a sample of 198 depressed patients (145 female, 53 male) retrospective histories of the illnesses were collected during a depression-free interval, based on a catalogue containing 38 symptom items and the course of the depression (including the interval personality). A cluster analysis on persons and items filtered out an endogenous depressive item profile, corresponding with the clinical syndrome of patients diagnosed as endogenous depressives in the clinics, although determined without reference to the clinical diagnoses. Our study supports many results from earlier multivariate statistical studies. We consider our data to be an essential contribution towards the establishment of a multiaxial clinical picture.
