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.
通过半结构化访谈对31名首发精神病患者进行评估，以确定是否存在8种DSM-III前驱症状。根据患者、一名知情者以及融合了前两种信息来源的评估者，计算相同症状的评估者间信度数据。以kappa系数和百分比一致性报告的信度水平总体上是可以接受的。
