Causes and consequences of duration of untreated psychosis in schizophrenia
Open accessAbstract
Background: It is unclear what determines duration of untreated psychosis (DUP) in schizophrenia and why long DUP predicts poor outcome. Aims: First, to test the hypothesis that specific patterns of symptoms and social functioning acting before treatment prolong DUP. Second, to clarify the mechanisms linking DUP with recovery after treatment. Method: Two hundred and forty-eight consecutive first admissions with schizophrenia were interviewed to assess DUP, symptoms and social functioning at admission, and symptoms were re-assessed after 6–12 weeks. Results: Median DUP was 12 weeks. Long DUP was predicted by poor insight, social isolation and preserved coping skills, but not by demographic factors. Even allowing for all these variables, long DUP predicted poor outcome. Conclusions: Longer DUP results partly from a pattern of symptoms and social functioning which reduces concern by the sufferer and relevant others. DUP's relationship to outcome is strongest in the initial months of psychosis. This has implications for targeting early intervention.

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.
