A Confirmatory Factor Analysis of the Dementia Attitude Scale (DAS) in a European Case Series of Caregivers of People with Dementia Enrolled in the RECage Study.

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 Dementia Attitude Scale (DAS) is a validated instrument used to capture the affective, behavioural, and cognitive components of attitudes toward people living with dementia (PLwD). This study conducts confirmatory and exploratory factor analyses (CFA and EFA) of the DAS assessed by caregivers of PLwD and BPSD enrolled in the RECage multicentre clinical trial.
methodsThe baseline questionnaire was completed by 485 caregivers (29.7% male, 70.3% female), from six European countries, reflecting diverse cultural contexts. CFA tested the two-factor structure of the original model, while EFA thoroughly explored the factor structure.
resultsThe CFA results showed a poor model fit, with significant deviations from ideal values for RMSEA (0.0861), SRMSR (0.0781), and CFI (0.7117), showcasing an inadequate representation of the data. EFA revealed a three-factor structure, explaining the 45.2% variance for social comfort, 28.8% for social discomfort, and 25.9% for dementia knowledge. The social comfort items reflected positive caregiver attitudes toward PLwD, while social discomfort captured feelings of discomfort and uncertainty about caregiving. Dementia knowledge included items related to understanding dementia's symptoms and needs.
conclusionsThe three-factor model highlights the importance of emotional comfort, knowledge of dementia, and social discomfort as key dimensions in caregiver attitudes.
