Further Replication of Factors of Psychopathology in the Interview,Ward Behavior and Self-Reported Ratings of Hospitalized Depressed Patients

Factors of psychopathology in the interview, ward behavior, and self-reported ratings were initially obtained for 124 depressed patients from nine hospitals and subsequently replicated in an independent sample of 648 depressed patients from these same plus one additional hospital. The present study provided a further test of the generalizability and stability of these factors in a third independent sample of 325 depressed patients from these same hospitals. These factors appeared to be quite stable across the three studies and could be categorized into 10 major areas of psychopathology: Depressed Mood, Hostility, Guilty-Ashamed, Anxiety, Sleep Disturbances, Interest and Involvement in Activities, Paranoid Projections, Cognitive Loss, Apathy-Motor Retardation, and Hypochondriasis.
