The Spanish version of the Child Health and Illness Profile-Adolescent Edition (CHIP-AE)

Abstract

The aim of the study was to obtain a conceptually equivalent Spanish version of the Child Health and Illness Profile-Adolescent Edition (CHIP-AE), and to test its feasibility, reliability and preliminary construct validity. The methodology used for adaptation was forward-back translation, including two focus groups with adolescents and a panel of experts. Reliability and validity were assessed in healthy convenience samples from school settings (n = 417). Three different illness groups (n = 67) were used to examine differences in health status between healthy, acutely ill, chronically ill and mentally ill adolescents. Preliminary construct validity was examined by comparing mean scores for each of the subdomains to determine if they differed in predicted ways according to age, gender and illness group. The majority of items (154 out of 203) were conceptually equivalent to the original version. Some items (46) had to be modified to increase clarity and/or to adapt them for use in Spain and 3 items were considered not applicable. Single construct subdomains achieved alpha coefficients between 0.65 and 0.92, and intraclass correlation coefficients (ICC) between 0.57 and 0.93. The mentally ill group presented the worst scores in most domains. The Spanish CHIP-AE is acceptable for Spanish adolescents and shows adequate metric characteristics, which are similar to those reported in the US version.
