Translation and validation of the gross motor function classification system among Nepalese children with cerebral palsy: A cohort study.

Research Report.

ABSTRACT:

Background: Self-reported outcome measures are an increasingly important component of the assessment and
management of children with cerebral palsy. The Gross Motor Functional Classification System
expanded and revised version (GMFCS-E&R) is one of the most commonly used health related
quality of life measures and has been translated into multiple languages. There are currently no
self-reported questionnaires available in Nepali. Therefore the aim of this study was to translate
and cross-culturally adapt the (GMFCS-E&R) into Nepali and to evaluate its measurement
properties in the 6-18 year age group.

Results: Of the total 110 participants 69 (62.7%) were male and 41 (37.3%) were females. Mean age of
the children was 12.47 and the Standard Deviation of 4.64. Based on the Gross Motor Function
Classification System, we found that 39 (35.5%) of participants lies in level I and secondly in
Level 5 there were 24 (21.8%). The acceptable Content validation index (CVI) was found to be
0.898. Measurement property testing revealed inter rater reliability internal consistency
Cronbach’s α≥0.991.

Conclusion: The Nepali version of the PEDsQL-CP was easily understood and demonstrated excellent
reliability and validity measurement properties. It would be recommended as a quality of life
measure of Nepali children with cerebral palsy in both clinical practice and for research
purposes.
