title: The validity of the ICD-10 classification of recurrent affective disorders: do endogenous and psychogenic depressions form a homogeneous diagnostic group?
abstract: Fifty-five hospital-treated patients with the ICD-10 diagnosis of 'recurrent depressive episode(s)' were classified according to the Newcastle Depressive Diagnostic Scale as having either psychogenic (n = 25) or endogenous (n = 30) depression and interviewed using several inventories on personality and psychopathology (Composite International Diagnostic Interview, Symptom Check List, Inventory of Interpersonal Problems, IIP, NEO Five-Factor Personality Inventory, Social Adjustment Scale, Questionnaire of the Motivation to Seek Psychotherapy). Except for the IIP, individual subscales disclosed significant differences between the two groups. In light of these results, the grouping of these two disorders into one diagnostic group in the ICD-10 is critically discussed.
