The EAWE (Examination of Anomalous World Experience) is a newly developed, semi-structured interview that aims to capture anomalies of subjectivity, common in schizophrenia spectrum disorders, that pertain to experiences of the lived world, including space, time, people, language, atmosphere, and certain existential attitudes. By contrast, previous empirical studies of subjective experience in schizophrenia have focused largely on disturbances in self-experience.
To assess the reliability of the EAWE, including internal consistency and interrater reliability.
In the course of developing the EAWE, two distinct studies were conducted, one in the United States and the other in Slovenia. Thirteen patients diagnosed with schizophrenia spectrum or mood disorders were recruited for the US study. Fifteen such patients were recruited for the Slovenian study. Two live interviewers conducted the EAWE in the US. The Slovenian interviews were completed by one live interviewer with a second rater reviewing audiorecordings of the interview. Internal consistency and interrater reliability were calculated independently for each study, utilizing Cronbach's α, Spearman's ρ, and Cohen's κ.
Each study yielded high internal consistency (Cronbach's α >0.82) and high interrater reliability for total EAWE scores (ρ > 0.83; average κ values were at least 0.78 for each study, with EAWE domain-specific κ not lower than 0.73).
The EAWE, containing world-oriented inquiries into anomalies in subjective experience, has adequate reliability for use in a clinical or research setting.
异常世界体验检查（EAWE）是一种新开发的半结构化访谈，旨在捕捉精神分裂症谱系障碍中常见的主观异常，这些异常与生活世界的体验有关，包括空间、时间、人物、语言、氛围和某些存在态度。相比之下，之前关于精神分裂症主观体验的实证研究主要集中在自我体验的干扰上。
评估EAWE的可靠性，包括内部一致性和评分者间信度。
在开发EAWE的过程中，进行了两项不同的研究，一项在美国，另一项在斯洛文尼亚。美国的研究招募了13名被诊断患有精神分裂症谱系或情绪障碍的患者。斯洛文尼亚的研究招募了15名此类患者。在美国，由两名现场访谈者进行EAWE访谈。斯洛文尼亚的访谈由一名现场访谈者完成，第二名评分者对访谈的录音进行审查。每项研究都独立计算内部一致性和评分者间信度，使用克朗巴赫α系数、斯皮尔曼ρ系数和科恩κ系数。
每项研究都产生了较高的内部一致性（克朗巴赫α系数>0.82）和EAWE总分的较高评分者间信度（ρ>0.83；每项研究的平均κ值至少为0.78，EAWE特定领域的κ值不低于0.73）。
EAWE包含对主观体验异常的面向世界的询问，在临床或研究环境中使用具有足够的可靠性。
