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.
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.
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.
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.
成人执行功能行为评定量表（BRIEF - A）有自评和他评两种形式。每种形式包含九个分量表以评估执行功能。本研究旨在检验精神分裂症患者中各分量表的单维性以及两种形式在项目水平上的一致性。
从一家精神科中心招募了197名精神分裂症患者和194名照料者。在精神分裂症患者中，44.2%为男性，平均年龄44.0岁。在完成他评量表的照料者中，27.8%为男性，平均年龄60.4岁。使用Rasch分析评估BRIEF - A各分量表的单维性。采用加权kappa系数和一致性百分比来检验两种形式在项目水平上的一致性。
自评量表各分量表所有项目的拟合均方和 outfit 均方为0.65 - 1.48。除计划/组织分量表外，他评量表中其他八个分量表的项目符合拟合均方和 outfit 均方的标准（0.69 - 1.44）。自评和他评量表九个分量表标准化残差的主成分分析分别为1.4 - 1.8和1.5 - 2.1。两种形式之间的加权kappa系数和一致性百分比分别为0.02 - 0.33和36.8% - 63.4%。
BRIEF - A对精神分裂症患者具有可接受的单维性。两种形式之间轻微到中等程度的项目水平一致性使得在解释结果时需要谨慎，并纳入多个信息提供者的观点，以确保对执行功能进行更全面和准确的评估。
