Reliability of Psychiatric Diagnosis: II. The Test/Retest Reliability of Diagnostic Classification

Helzer, John E.·1977·Archives of General Psychiatry

Abstract

In a study of interrater diagnostic reliability, 101 psychiatric inpatients were independently interviewed by physicians using a structured interview. Newly admitted patients were randomly selected and examined by one of three psychiatrists. A second psychiatrist reexamined the same patient about 24 hours later. Interviews from the two examinations were evaluated independently and diagnoses were made on the basis of objective criteria. The degree of diagnostic agreement for the two examinations were calculated using the kappa statistic. Agreement was found to be high as compared to other studies in the psychiatric literature, despite the fact that in most previous investigations diagnoses were not made independently. The results were also compared to studies of reliability of medical judgments. Possible reasons for the high interrater reliability are discussed and include the use of a structured interview and objective diagnostic criteria.

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.
