Validation and reliability of Arabic version of Children's Hand-use Experience Questionnaire (CHEQ) for children with hemiparetic cerebral palsy.

The aim was to assess validation and reliability of Arabic version of Children's Hand-use Experience Questionnaire (CHEQ) for children with hemiparetic cerebral palsy (HCP). Ninety-nine children aged 6-18 years diagnosed with HCP participated in the study. The CHEQ was used to evaluate the hand-use experiences of children with cerebral palsy (CP). In the expert opinion questionnaire, the average percentage score of agreement on grasp efficacy was 91.5%. The highest percentage (93.3%) was for time taken. Agreement on CHEQ ranged from 91.5 to 93.3% indicating that the content validity of the prototype is supported by the expert ratings. Fitting indices showed that the one-factor structure of the CHEQ has a good and acceptable fit in children with HCP aged 6-18 years. All factor loads of the CHEQ items were greater than 0.7 and significant. Cronbach's alpha coefficient in this study was 0.921, thus showing that the questionnaire had high internal consistency.
