Arabic translation and validation of the dementia knowledge assessment scale (DKAS-A) and public knowledge assessment in the United Arab Emirates.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Dementia is a neurocognitive disorder affecting millions, with prevalence projected to triple by 2050. Assessing dementia knowledge is crucial for its prevention, diagnosis, and treatment. This study developed the Arabic version of the Dementia Knowledge Assessment Scale (DKAS-A) to facilitate this evaluation. We conducted a cross-sectional study among adults in the United Arab Emirates (UAE) between December 2023 and January 2024. We collected participants’ data using a sociodemographic form and the DKAS, which was translated into Arabic using the Translation, Review, Adjudication, Pretest, and Documentation (TRAPD) method. We verified the translation’s validity, internal consistency, and reliability. The DKAS-A demonstrated acceptable internal consistency (Cronbach’s alpha = 0.7), very strong equivalence to the original English tool (Pearson’s correlation coefficients > 0.8), and moderate test-retest reliability (intraclass correlation coefficient = 0.67). Confirmatory Factor Analysis (CFA) supported a revised 21-item version for the DKAS-A. Of 912 participants, 405 completed the Arabic version of the questionnaire. Only 22.8% demonstrated moderate knowledge of dementia. Higher knowledge levels were significantly associated with female gender, involvement in the medical field, higher education, and experience with People with Dementia (PwD). The DKAS-A was successfully developed and validated. The inadequate dementia knowledge in the UAE necessitates the development of a national dementia plan to raise awareness and decrease the disease’s burden.
