Validity and reliability of Persian version of Craig Hospital Inventory of Environmental Factors (CHIEF) in children with cerebral palsy
ObjectivesThe aim of this study was to translate the Craig Hospital Inventory of Environmental Factors (CHIEF) into Persian language and to evaluate the validity and reliability of Persian version of CHIEF to use for children with cerebral palsy.
MethodsThe CHIEF was translated from English into Persian based on the International Quality of Life Assessment (IQOLA) approach. The Persian version of the CHIEF has been completed with a convenience sample of 75 caregivers of children with cerebral palsy. Two weeks after the first completion, 20 caregivers completed CHIEF again in the retest session. The CHIEF questionnaire consists of 25 items divided in to 5 subscales. Its item discriminant validity was calculated using spearman's rank correlation, test-retest reliability using Intraclass Correlation Coefficient (ICC) and Standard Error of Measure (SEM), and Internal consistency using Cronbach's coefficient α.
ResultsThe results demonstrated that more than 96% of items correlated strongly with its own subscale rather than other subscales (r > 0.40). The values of the ICC were > 0.70 and the values of the SEM were ≤ 1 for the score of subscales and total score. Cronbach's coefficient α for the overall scale was 0.86.
ConclusionsThe Persian version of the CHIEF has acceptable levels of face validity, construct validity, item discriminant validity, test-retest reliability, and internal consistency to use for children with cerebral palsy.
