title: Assessment of quality of life in adolescent patients with orthopaedic problems: are adult measures appropriate?
abstract: New pressures of accountability brought on by a rapidly evolving system of health care financing have underscored the need for standardized, valid measures of patient outcome that reflect the effect of clinical intervention on all aspects of quality of life. In response, there has been a burgeoning interest in the area of outcomes assessment and measurement of quality of life after orthopaedic intervention in adults, but less attention has been focused on the assessment of broadly defined outcomes in children. In an effort to borrow from the broader adult experience in this area, the authors sought to examine whether the Medical Outcomes Study Short Form 36 (SF-36) or the EuroQol questionnaire, widely accepted adult health status measures, would be valid in this setting. These two measures were administered to 196 adolescent patients (10-18 years old) seeking orthopaedic evaluation. Tests of scale properties and construct validity show that these properties are maintained in this population, but neither instrument reflected known differences in health status among this cohort. Most importantly, both the SF-36 and the EuroQol exhibited serious ceiling effects (most respondents scored at the top of their scales), despite evidence indicating those patients often had suboptimal health status. Thus, neither the SF-36 nor the EuroQol is valid for use in this population. The assessment of pediatric health status demands outcomes measures specifically designed to reflect the unique needs of this population.
