Ej. Bromet et al., THE SUFFOLK COUNTY MENTAL-HEALTH PROJECT - DEMOGRAPHIC, PREMORBID ANDCLINICAL CORRELATES OF 6-MONTH OUTCOME, Psychological medicine, 26(5), 1996, pp. 953-962
The diagnostic specificity and predictive utility of the classical pro
gnostic indicators in schizophrenia were examined in psychotic patient
s enrolled in the Suffolk County Mental Health Project. First-admissio
n psychotic patients with schizophrenia (N = 96), major depression (N
= 42), and bipolar disorder (N = 64) drawn from 10 facilities in Suffo
lk County, New York, were assessed during their initial hospitalizatio
n and at 6-month follow-up. Longitudinal consensus diagnoses were dete
rmined after the 6-month interview. The diagnostic groups shared simil
ar background characteristics, but schizophrenics had poorer pre-morbi
d adjustment, longer periods of psychosis before hospitalization and m
ore negative symptoms initially. Except for rehospitalization, schizop
hrenics had the worst and bipolars the best functioning at follow-up.
Among the classical prognostic indicators, the best predictor of 6-mon
th outcome for each diagnostic group was premorbid functioning.
