National Institute of Mental Health Longitudinal Study of Chronic Schizophrenia: Prognosis and Predictors of Outcome

Breier, Alan·1991·Archives of General Psychiatry

Abstract

We performed a longitudinal study of chronic schizophrenic patients who were hospitalized for research purposes at the National Institute of Mental Health (NIMH) Intramural Program in the 1970s and early 1980s. We assessed present course, outcome and predictor data from the initial cohort of 58 young chronic schizophrenic patients who were followed up for 2 to 12 years following their NIMH index hospitalization. At follow-up, the sample showed substantial functional impairment and levels of symptoms with only about 20% of the sample demonstrating a good outcome. In addition, strong intercorrelation was noted among the symptom and functioning indexes at follow-up. Moreover, neuropsychologic tests of frontal cortical functioning were significantly correlated with outcome levels of negative symptoms and social functioning but not with levels of positive symptoms. During the period from the index hospitalization to the follow-up assessment, 78% of the sample suffered a relapse, 38% attempted suicide and 24% had episodes of major affective illness. Furthermore, levels of positive and negative symptoms ascertained when patients received optimal neuroleptic treatment during the index hospitalization significantly predicted outcome levels of symptoms and functioning and time spent hospitalized during the follow-up period. In contrast, levels of index positive and negative symptoms ascertained during the drug-free state did not predict outcome symptoms or functioning. These data suggest that treatment response is a critical predictor variable. We examined the implication of these data for the course of illness in schizophrenics.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
