Item Analysis of the Behavior Rating Inventory of Executive Function-Adults Version Using the Rasch Model in Two Forms for People With Schizophrenia in Taiwan
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.
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.
