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.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe 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.
methodsA 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.
resultsThe 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.
conclusionThe 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.
