This paper presents further characteristics of a four-group typology of depressed patients, previously derived by cluster analysis. The four groups comprise psychotic depressives, anxious depressives, hostile depressives, and young depressives with personality disorder. Additional correlates were examined in 165 depressives. Selfreports and ratings by relatives showed symptomatic differences between groups. Routine clinical diagnoses of psychotic and neurotic depression overlapped with the typology, which however contained three diverse neurotic groups. Psychotic depressives were mostly treated as hospitalized inpatients, young depressives with personality disorders as outpatients, while anxious depressives tended to be treated as day patients. Anxious depressives most often received medication prior to admission. Subsequent to admission there were considerable differences in medications prescribed. These findings provide partial validation for the typology since its elements are perceived widely and bear important relationships to treatment.
