A Selective Review of Recent North American Long-term Followup Studies of Schizophrenia

Open access
McGlashan, T. H.·1988·Schizophrenia Bulletin

Abstract

North American outcome studies of schizophrenia conducted within the past quarter century are reviewed if their minimum average followup is 10 years and they meet at least some modern design criteria. Ten such investigations are described and summarized. Taken as a whole, they demonstrate that schizophrenia can be a chronic disease whose outcome on the average is worse than that of other major mental illnesses. It is associated with an increased risk for suicide, physical illness, and mortality. The schizophrenic process, however, is not relentlessly progressive, as originally described, but appears to plateau after 5-10 years of manifest illness. Overall, outcome is heterogeneous, but much of the variance can be linked to sample characteristics, including expressions of psychopathology (broad vs. narrow diagnostic criteria, subtypes, and comorbidity), dimensions of chronicity (length of manifest illness, treatment resistance, age of onset, and institutionalization), and other predictor variables (gender, marital status, socioeconomic status, physical setting, and premorbid health). Long-term followup studies have yet to demonstrate clearly any effect of treatment on the natural history of schizophrenia. Finally, these studies support a broad definition of schizophrenia.

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.
