Examination of Anomalous World Experience: A Report on Reliability.

Abstract

BACKGROUND 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. AIM To assess the reliability of the EAWE, including internal consistency and interrater reliability. SAMPLING AND METHODS 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. RESULTS 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). CONCLUSION The EAWE, containing world-oriented inquiries into anomalies in subjective experience, has adequate reliability for use in a clinical or research setting.
