title: The reliability of DSM-III prodromal symptoms in first-episode psychotic patients.
abstract: Thirty-one first-episode psychotic patients were assessed via a semistructured interview to determine the presence or absence of the 8 DSM-III prodromal symptoms. Interrater reliability data were calculated for the same symptoms according to the patient, an informant and the raters blending the previous 2 sources of information. Levels of reliability, reported as kappa and percentage agreements, were generally acceptable.
