To validate a Spanish language version of the Childhood Health Assessment Questionnaire (CHAQ) for use in Costa Rica and to evaluate the feasibility, reliability, and cross cultural equivalency of this version.
The original questionnaire, translated without modification into Spanish, was administered to 12 children, all above 10 years of age, with the diagnosis of juvenile chronic arthritis (JCA) and to their parents. There were several problems in comprehension, and self-administration with this version was not possible. For this reason a teacher and a psychologist were consulted to create a modified Costa Rican version. We administered this 2nd version to 46 children with JCA and 62 of their parents.
The modified Costa Rican HAQ (CR-CHAQ) was self-administered by 93.5% of the patients and 84% of the parents. The median time to complete the questionnaire was 12 min for the children, 10 min for the parents. The main difficulty in comprehension was the pain score for both groups. Test-retest (Spearman R = 0.73) and interobserver (Spearman R = 0.70) reliability were good. Validity of the instrument was confirmed by the high correlation between the disability and discomfort scores and conventional clinical variables. There was satisfactory correlation between the disability score and conventional clinical variables. Discriminant validity was confirmed by the capacity of the CR-CHAQ to evaluate patients as being in different categories of disease activity.
After modifications, the CR-CHAQ achieved cross cultural equivalency.
