Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

• Turkish AAC-Q Score

  The Turkish version of the Adolescents and Adults Coordination Questionnaire (AAC-Q) is a 12-item self-report questionnaire designed to assess coordination difficulties in adolescents and adults. Each item is scored on a 5-point Likert scale, with higher scores indicating greater coordination difficulties.

  Assessments will be performed at baseline and repeated 7-10 days later to evaluate test-retest reliability.

• Adult Executive Functioning Inventory (ADEXI)

  Executive functioning will be assessed using the Adult Executive Functioning Inventory (ADEXI), a 14-item self-report questionnaire evaluating working memory and inhibition. Higher scores indicate greater executive functioning difficulties.

  Assessments will be performed at baseline

Secondary Outcomes (5)

• Lower Extremity Motor Coordination Test

  Assessments will be performed at baseline

• Star Excursion Balance Test

  Assessments will be performed at baseline

• Nine-Hole Peg Test

  Assessments will be performed at baseline

• Ruler Drop Test

  Assessments will be performed at baseline

• Stroop Test

  Assessments will be performed at baseline
