Validity of the Spanish version of the Child Health and Illness Profile-Adolescent Edition (CHIP-AE).
OBJECTIVE
To assess the structural, convergent, discriminant, and criterion validity of the Spanish version of the Child Health and Illness Profile-Adolescent Edition (CHIP-AE) and to compare results with the U.S. version.


METHODS
A sample of adolescents aged 12 to 19 attending schools and representative of the school-aged population in Barcelona, Spain (n = 902).


METHODS
Exploratory factor analyses were performed, and results compared with the U.S. version. The Child Depression Inventory (CDI) and the State-Trait Anxiety Inventory (STAIC) were administered to a subgroup of adolescents to assess convergent and discriminant validity. Criterion validity was assessed by using receiver operating characteristic (ROC) curves to examine the ability of the CHIP-AE academic performance subdomain to predict school grades.


RESULTS
The Spanish version has 6 defined domains with a factor structure showing minor differences from the U.S. version. Higher correlations were found between the CDI and STAIC and CHIP-AE subdomains of emotional discomfort and self-esteem (range. 0.48-0.80, P<0.01) than with scales measuring dissimilar concepts. The area under the ROC curve was 0.83 (95% confidence interval, 0.75-0.92) for the number of failed subjects (none/one or more) related to academic performance.


CONCLUSIONS
The underlying theoretical model of the Spanish version of the CHIP-AE functions well in Spain, and the Spanish version has acceptable levels of convergent, discriminant, and criterion validity. Sensitivity to change and the use of the health profiles need to be assessed.
