Data confidence 85 high
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The Boston Carpal Tunnel Questionnaire is designed for use by patients with carpal tunnel syndrome. However, its use in the Republic of Kazakhstan among the Kazakh-speaking population is unavailable due to the lack of a translated version. The aim of this study was to translate and culturally adapt The Boston Carpal Tunnel Questionnaire into the Kazakh language, as well as to evaluate its reliability and validity. The study included 64 Kazakh-speaking patients with clinically confirmed carpal tunnel syndrome. Statistical analysis involved descriptive statistics and psychometric analysis to assess reliability (internal consistency) and construct validity. The Kazakh version of the Boston Carpal Tunnel Questionnaire demonstrated high reliability with Cronbach's alpha ranging from 0.974 to 0.985. Content validity revealed ceiling effects and less pronounced floor effects. Construct validity was acceptable for several Boston Carpal Tunnel Questionnaire items along with the corresponding subscales of EQ-5D-5L. The results of this study confirm the high reliability and satisfactory validity of Boston Carpal Tunnel Questionnaire for assessing patients with carpal tunnel syndrome in the Kazakh-speaking population. However, identified limitations highlight the need for further refinement of the instrument and additional research on a more diverse sample.Keywords:carpal tunnel syndrome, questionnaire, adaptation, validation.
