DOI : 10.5606/tftrd.2021.4091 Objectives: The aim of the present study is to develop a Turkish version of the ABILHAND-Kids Survey, which evaluates upper extremity function in children with cerebral palsy (CP), and to carry out a validity and reliability study of the survey for Turkish CP patients.

Materials and methods: Between November 2016 and March 2017, a total of 109 pediatric CP patients (62 males, 47 females; mean age 9.3±2.9 years; range, 6 to 15 years) followed in our outpatient clinic were included. The demographic characteristics and type of CP of the patients were recorded. A functional evaluation was made using the ABILHAND-Kids and Manual Ability Classification System (MACS) surveys. The reliability of the surveys was tested based on internal consistency (Cronbach`s α) and test-retest (intraclass correlation coefficient [ICC]) methods. The validity of the approach was evaluated using converted scores from an ABILHAND-Kids Rasch analysis and a correlation of the MACS levels.

Results: The ICC value for the test/retest reliability was 0.98 and internal consistency was 0.94. A strong negative correlation was found between the Turkish version of the ABILHAND-Kids and MACS surveys (r=-0.849; p<0.001). A Rasch analysis indicated good item fit, unidimensionality, and model fit.

Conclusion: The Turkish version of the ABILHAND-Kids survey is a reliable and valid scale for the assessment of manual ability in Turkish children with CP. Keywords : ABILHAND-kids, cerebral palsy, reliability, Turkish, validity
