Our aim in this study is to investigate the cross-cultural adaptation, validation and reliability of Children’s Hand-use Experience Questionnaire (CHEQ). Methods: Ninety-five children between 6 and 18 years of age with hemiparetic Cerebral Palsy (CP) were included in this study. Gross Motor Function Classification System (GMFCS) was used to determine their motor levels, Manual Ability Classification System (MACS) was used to determine their manual ability, Pediatric Evaluation of Disability Inventory (PEDI) was used to determine their disability level and Children’s Hand-use Experience Questionnaire (CHEQ) was used to determine their hand use ability. Results: Investigating reliability of CHEQ, 35 children with hemiparetic CP were evaluated 1week interval. The test-retest reliability was described by using intra-class correlation coefficient (ICC). Convergent and divergent construct validities were assessed by examining the Spearman’s correlation coefficients of the CHEQ compared to MACS and GMFCS and PEDI. Reliability were tested by using ICC and found to be 1.00. The ‘activities performed independently’ section of the CHEQ had statistically significant and good correlations (p=0.001) with the MACS and the self-care section of the PEDI. It had statistically significant but weak correlation (p=0.001) with the GMFCS 1 PT, Ph.D., Assistant Prof. Beykent University, 4441997, Vocational School, Department of Therapy and Rehabilitation, mahsumeren@beykent.edu.tr 2 Professor, Hacettepe University, 0. 312 305 50 00, Faculty of Health Sciences, Department of Ergotherapy, fztgamze@yahoo.com 3 PT, Ph.D., Assistant Prof., Muş Aplarslan University, +90 416 249 49 49, Faculty of Health Sciences, Department of Physiotherapy and Rehabilitation, fzthalilalkan@hotmail.com SANITAS MAGISTERIUM Received: 13.10.2021 Published: 01.01.2022 Copyright © 2022 https://dergipark.org.tr/ijhadec January 2022 • RELIABILITY AND VALIDITY OF TURKISH VERSION OF CHILDREN’S HAND USE EXPERIENCE QUESTIONNAIRE FOR CHILDREN WITH HEMIPARETIC CEREBRAL PALSY
