Turkish Adaptation and Validation of the Adolescents and Adults Coordination Questionnaire
An observational study of Motor Coordination Assessment, run by Gulser CINBAZ.
Trial 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.

About this study
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.
Read the detailed description
Coordination is a fundamental motor control ability that enables individuals to perform purposeful, accurate, and efficient movements during daily activities. Reliable assessment of coordination is important for identifying motor difficulties, planning rehabilitation, and monitoring treatment outcomes in both clinical practice and research.
The Adolescents and Adults Coordination Questionnaire (AAC-Q) is a self-report questionnaire developed to evaluate coordination difficulties in adolescents and adults. Although the questionnaire has demonstrated satisfactory psychometric properties in its original language, no validated Turkish version is currently available.
This prospective observational study aims to translate and culturally adapt the AAC-Q into Turkish and to evaluate its psychometric properties in Turkish-speaking adults. The adaptation process will include forward translation, backward translation, expert review, and pilot testing. The Turkish version of the questionnaire will subsequently undergo comprehensive psychometric evaluation.
Participants aged 18 to 35 years will complete the Turkish AAC-Q together with the Adult Executive Functioning Inventory. Coordination and motor performance will be assessed using the Lower Extremity Motor Coordination Test, Star Excursion Balance Test, Nine-Hole Peg Test, Ruler Drop Test, and Stroop Test. Construct validity, criterion validity, internal consistency, and test-retest reliability will be examined using established statistical methods.

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 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.
Measured: Assessments will be performed at baseline
Secondary outcomes (5)
Lower Extremity Motor Coordination Test
Lower extremity motor coordination will be evaluated using the Lower Extremity Motor Coordination Test. Participants will alternately touch two targets with the great toe for 20 seconds while seated. The average number of correct touches from two trials will be recorded.
Measured: Assessments will be performed at baseline
Star Excursion Balance Test
Dynamic balance will be assessed using the Star Excursion Balance Test. Participants will reach in the anterior, posteromedial, and posterolateral directions while maintaining single-leg stance. The average reach distance from three trials in each direction will be recorded.
Measured: Assessments will be performed at baseline
Nine-Hole Peg Test
Manual dexterity and upper extremity coordination will be assessed using the Nine-Hole Peg Test. The time required to place and remove nine pegs will be recorded separately for each hand.
Measured: Assessments will be performed at baseline
Ruler Drop Test
Reaction time will be evaluated using the Ruler Drop Test. Participants will catch a falling ruler as quickly as possible, and the catching distance will be recorded as an indicator of reaction time.
Measured: Assessments will be performed at baseline
Stroop Test
Executive function, selective attention, cognitive flexibility, and resistance to interference will be assessed using the Stroop Test (Çapa Form). Completion time and error rate will be recorded.
Measured: Assessments will be performed at baseline

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 10 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Turkish AAC-Q Score (time frame: Assessments will be performed at baseline and repeated 7-10 days later to evaluate test-retest reliability.). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Aug 2026.
