This study was designed to test the reliability and validity of an ins
trument to assess adolescent health status. Reliability and validity w
ere examined by administration to adolescents (ages 11-17 years) in ei
ght schools in two urban areas, one area in Appalachia, and one area i
n the rural South. Integrity of the domains and subdomains and constru
ct validity were tested in all areas. Test/retest stability, criterion
validity, and convergent and discriminant validity were tested in the
two urban areas. Iterative testing has resulted in the final form of
the CHIP-AE (Child Health and Illness Profile-Adolescent Edition) havi
ng 6 domains with 20 subdomains. The domains are Discomfort, Disorders
, Satisfaction with Health, Achievement (of age-appropriate social rol
es), Risks, and Resilience. Tested aspects of reliability and validity
have achieved acceptable levels for all retained subdomains. The CHIP
-AE in its current form is suitable for assessing the health status of
populations and subpopulations of adolescents. Evidence from test-ret
est stability analyses suggests that the CHIP-AE also can be used to a
ssess changes occurring over time or in response to health services in
terventions targeted at groups of adolescents.
