The Psychotic Symptom Rating Scales (PSYRATS): their usefulness and properties in first episode psychosis

Drake, Richard, Haddock, Gillian, Tarrier, Nicholas, Bentall, Richard, Lewis, Shôn·2007·Schizophrenia Research

Abstract

The aim of this study was to investigate the reliability, validity and structure of the Psychotic Symptom Rating Scales (PSYRATS) in 257 subjects presenting with acute first episodes of schizophrenia or related disorders. The PSYRATS have been shown to assess dimensions of hallucination and delusions reliably and validly in chronically psychotic patients but not in first episode patients. Item reliability was investigated and subscale performance compared to the PANSS. The PSYRATS had good inter-rater and retest reliability. Validity was good, as assessed by internal consistency, sensitivity to change, and in relation to the PANSS. There was evidence of two delusion factors and three for hallucinations. The scales are useful complements to existing measures of symptom severity.

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.
