目的：一般人群的纵向队列研究已经证明了自我报告的精神病经历的预后有效性，但这些经验的可靠性和交叉验证与访谈为基础的措施的数据是稀疏的。方法：采用社区精神体验评定量表（CAPE 42）对765名普通人群进行亚临床精神病表型的测量。随访时对510例患者进行了精神分裂症结构化访谈（SIS-R）、简明精神病评定量表（BPRS）和CAPE 42量表的评定。基线自我报告的精神病维度与随访时基于访谈的同等维度特异性和独立相关（标准化效应量为0.4-0.5）与自评量表（标准化效应量为0.6-0.8）比较。
Objective: General population longitudinal cohort studies have demonstrated the prognostic validity of self-reported psychotic experiences, but data on reliability and cross-validation with interview-based measures of these experiences are sparse. This study tested the reliability and validity of the Community Assessment of Psychic Experiences (CAPE42).Method: At baseline, the CAPE42 was used to measure the subclinical psychosis phenotype in a general population sample (n = 765). At follow-up (mean interval: 7.7 months), the Structured Interview for Schizotypy, Revised (SIS-R), the Brief Psychiatric Rating Scale (BPRS), and the CAPE42 were administered (n = 510).Results: Baseline self-reported dimensions of psychosis were specifically and independently associated with their equivalent interview-based dimension at follow-up (standardized effect sizes of 0.4-0.5) and with their equivalent self-reported measure (standardized effect sizes of 0.6-0.8).Conclusion: The results indicate that self-reported dimensions of psychotic experiences in general population samples appear to be stable, reliable and valid.
