Turkish cultural adaptation and psychometric evaluation of the children activity scales-parent and teacher forms (ChAS-P/T).

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
Background: Developmental Coordination Disorder (DCD) is a prevalent neurodevelopmental condition that negatively affects children's participation in daily activities at home and school. Screening tools based on parent and teacher reports are particularly valuable for early identification, as they capture functional performance in natural contexts. The Children Activity Scales-Parent and Teacher Forms (ChAS-P/T) were developed for this purpose; however, a Turkish version for Turkish children has not previously been available. Objective: This study aimed to translate and culturally adapt the ChAS-P/T into Turkish and to examine its reliability and validity in children aged 4-8 years. Methods: The study followed internationally recommended guidelines for cross-cultural adaptation and psychometric validation. The ChAS-P/T was translated, culturally adapted, and pre-tested before psychometric evaluation. Parents and teachers of 340 Turkish children aged 4-8 years, including typically developing children and 34 children diagnosed with DCD, participated. The psychometric evaluation assessed the reliability, construct validity, discriminant validity, and criterion-related validity of the Turkish version. Results: The Turkish ChAS-P and ChAS-T demonstrated excellent internal consistency and strong test-retest reliability. Confirmatory factor analyses supported the original four-factor structure of the parent form and three-factor structure of the teacher form. Significant group differences supported discriminant validity. ROC analyses indicated good to excellent criterion-related validity, with optimal cut-off scores yielding high sensitivity and specificity. Strong correlations between parent and teacher reports further supported convergent validity across informants. Conclusions: The Turkish versions of the ChAS-P and ChAS-T are reliable and valid screening instruments for identifying children aged 4-8 years at risk for DCD. Their robust psychometric properties and multi-informant structure support their use in clinical and educational settings to facilitate early identification and referral.
