Abstract

Background

The Behavior Rating Inventory of Executive Function-Adults version (BRIEF-A) consists of two forms, self-report and informant-report. 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.

Methods

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.

Results

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.

Conclusion

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.

《执行功能行为评定量表-成人版》（BRIEF-A）由自我报告和举报人报告两种形式组成。每份表格包含九个等级来评估执行功能。该研究旨在检查每个量表的单维性，以及两种形式在精神分裂症患者中项目水平上的一致性。方法从同一精神病学中心招募197名精神分裂症患者和194名护理人员。在精神分裂症患者中，44.2%为男性，平均年龄为44.0岁。在填写资料报告表的照顾者中，27.8%为男性，平均年龄60.4岁。使用Rasch分析评估每个BRIEF-A量表的单维性。加权kappa和协议的百分比被用来检查两种形式之间的项目级协议。结果自述表各量表各题的内均方和内均方在0.65 ~ 1.48之间。举报表中除计划/组织量表外，其余8个量表均符合中均方标准（0.69-1.44）。自我报告和举报人报告的标准化残差主成分分析分别为1.4 ~ 1.8和1.5 ~ 2.1。两种形式的加权kappa值和符合率分别为0.02 ~ 0.33和36.8% ~ 63.4%。结论BRIEF-A对精神分裂症患者具有可接受的单一性。这两种形式之间的项目一级的大致一致需要谨慎地解释结果，并纳入多个举报人的观点，以确保对执行职能作出更彻底和准确的评价。

期刊介绍： The International Journal of Methods in Psychiatric Research (MPR) publishes high-standard original research of a technical, methodological, experimental and clinical nature, contributing to the theory, methodology, practice and evaluation of mental and behavioural disorders. The journal targets in particular detailed methodological and design papers from major national and international multicentre studies. There is a close working relationship with the US National Institute of Mental Health, the World Health Organisation (WHO) Diagnostic Instruments Committees, as well as several other European and international organisations. MPR aims to publish rapidly articles of highest methodological quality in such areas as epidemiology, biostatistics, generics, psychopharmacology, psychology and the neurosciences. Articles informing about innovative and critical methodological, statistical and clinical issues, including nosology, can be submitted as regular papers and brief reports. Reviews are only occasionally accepted. MPR seeks to monitor, discuss, influence and improve the standards of mental health and behavioral neuroscience research by providing a platform for rapid publication of outstanding contributions. As a quarterly journal MPR is a major source of information and ideas and is an important medium for students, clinicians and researchers in psychiatry, clinical psychology, epidemiology and the allied disciplines in the mental health field.
