Turkish Adaptation and Validation of the Adolescents and Adults Coordination Questionnaire

Coordination is an essential component of motor control that supports the performance of daily activities and physical function. The Adolescents and Adults Coordination Questionnaire (AAC-Q) is a self-report instrument developed to identify coordination difficulties in individuals aged 16 years and older. However, a validated Turkish version is not currently available. This observational study aims to translate, culturally adapt, and evaluate the psychometric properties, including validity and reliability, of the Turkish version of the AAC-Q in Turkish-speaking adults. Participants will complete the Turkish AAC-Q together with established measures of executive functioning, coordination, balance, manual dexterity, reaction time, and cognitive performance to assess construct and criterion validity. Test-retest reliability will also be evaluated.
