AIM: To investigate the validity of the internet-based version of the Children's
Hand-use Experience Questionnaire (CHEQ) by testing the new four-category rating
scale, internal structure, and test-retest reliability.
METHOD: Data were
collected for 242 children with unilateral cerebral palsy (CP) (137 males and 105
females; mean age 9y 10mo, SD 3y 5mo, range 6-18y). Twenty children from the
study sample (mean age 11y 8mo, SD 3y 10mo) participated in a retest within 7 to
14 days. Validity was tested by Rasch analysis based on a rating scale model and
test-retest reliability by Kappa analysis and intraclass correlation coefficient
(ICC). RESULTS: The four-category rating scale was within recommended criteria
for rating scale structure. One item was removed because of misfit. CHEQ showed
good scale structure according to the criteria. The effective operational range
was >90% for two of the CHEQ scales. Test-retest reliability for the three CHEQ
scales was: grasp efficacy, ICC=0.91; time taken, ICC=0.88; and feeling bothered,
ICC=0.91. INTERPRETATION: The internet-based CHEQ with a four-category rating
scale is valid and reliable for use in children with unilateral CP. Further
studies are needed to investigate the validity of the internet-based version of
CHEQ for children with upper limb reduction deficiency or obstetric brachial
plexus palsy and the validity of the recommended improvements to the current
version.
