Reliability and validity of the positive and negative syndrome scale for schizophrenics
Abstract
The Positive and Negative Syndrome Scale (PANSS) was developed out of the need for a well-operationalized method of assessing these syndromes in schizophrenia, including their relationship to one another and to global psychopathology. We surveyed 82 acute and chronic schizophrenics to analyze the psychometric properties of the four PANSS scales. The interrater reliabilities were in the 0.80's, and significant correlations emerged with corresponding criterion measures. The PANSS positive and negative scales were inversely intercorrelated once their shared association with general psychopathology had been partialed out. The results support the scales' reliability, criterion-related validity, and construct validity, while cross-validating some of our previous findings.

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.
