Validity of Three Measures of Health‐related Quality of Life in Children with Intractable Epilepsy

Purpose: Validity studies on health‐related quality of life (HRQOL) scales for pediatric epilepsy are few, and cross‐validation with other samples has not been reported. This study was designed to assess the validity of three parent‐rated measures of HRQOL in pediatric epilepsy: (a) the Impact of Ch...

Zusammenfassung:Purpose: Validity studies on health‐related quality of life (HRQOL) scales for pediatric epilepsy are few, and cross‐validation with other samples has not been reported. This study was designed to assess the validity of three parent‐rated measures of HRQOL in pediatric epilepsy: (a) the Impact of Childhood Illness Scale (ICI), (b) the Impact of Child Neurologic Handicap Scale (ICNH), and (c) the Hague Restrictions in Epilepsy Scale (HARCES). Methods: Retrospective data were examined for 44 children with intractable epilepsy. Validity was assessed by evaluating differences across epilepsy severity groups as well as correlations between HRQOL scales and neurologic variables (seizure severity, epilepsy duration, current/prior antiepileptic medications) and psychosocial measures (emotional functioning, IQ, social skills, adaptive behavior). Scale overlap with a global QOL rating also was assessed. Results: The HRQOL measures were moderately to highly intercorrelated. The scales differed in terms of their associations with criterion measures. The HARCES was related to the highest number of neurologic variables and the ICNH to the fewest. All three scales were related to psychosocial functioning and to global quality of life. Conclusions: The results of this study suggest that the three measures are likely adequate measures of HRQOL for use in intractable childhood epilepsy. The measures were highly intercorrelated, and they were all broadly related to criterion measures reflecting specific domains of HRQOL as well as global QOL. Some differences between scales emerged, however, that suggest care in choosing HRQOL instruments for children with epilepsy.
