Among the various existing self-report instruments to measure paranoia, the Green et al.

Each form encompasses nine scales to assess executive functions. The study aimed to examine the unidimensionality of each scale and item-level agreement between the two forms in people with schizophrenia.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Methods</h3>\u0000 \u0000 <p>A total of 197 people with schizophrenia and 194 caregivers were recruited from a single psychiatric center. Among the people with schizophrenia, 44.2% were male, with a mean age of 44.0 years. As for the caregivers who completed the informant-report form, 27.8% were male, with a mean age of 60.4 years. The unidimensionality of each BRIEF-A scale was assessed using Rasch analysis. Weighted kappa and percentage of agreement were used to examine the item-level agreement between the two forms.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>The infit and outfit mean squares of all items on each scale of the self-report form were 0.65–1.48. Except for the Plan/Organize scale, the items of the other eight scales in the informant-report form met the standards for infit and outfit mean squares (0.69–1.44). Principal component analysis of the standardized residuals of the nine scales were 1.4–1.8 and 1.5–2.1 for the self-report and informant-report forms, respectively. Weighted kappa and percentage of agreement between the two forms were 0.02–0.33 and 36.8%–63.4% respectively.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>The BRIEF-A has acceptable unidimensionality for people with schizophrenia. The slight to fair item-level agreement between the two forms necessitates cautious explanation of results and incorporation of multiple informants' perspectives to ensure a more thorough and accurate assessment of executive functions.</p>\u0000 </section>\u0000 </div>","PeriodicalId":50310,"journal":{"name":"International Journal of Methods in Psychiatric Research","volume":"34 3","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mpr.70034","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144815004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
