Abstract:
OBJECTIVE: To identify and appraise published evidence of the measurement properties for epilepsy-specific patient-reported outcome measures (PROMs) of children's health-related quality of life (HRQoL).
METHODS: We searched multiple databases for studies evaluating the measurement properties of English-language epilepsy-specific PROMs of children's HRQoL. We assessed the methodological quality using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidance. We extracted data about the content validity, construct validity, internal consistency, test-retest reliability, proxy reliability, responsiveness, and precision, and assessed the measurement properties with reference to standardized criteria.
RESULTS: We identified 27 papers that evaluated 11 PROMs. Methodological quality was variable. Construct validity, test-retest reliability, and internal consistency were more commonly assessed. Quality of Life in Childhood Epilepsy (QoLCE) questionnaires are parent-reported and evaluated more than other PROMs; QoLCE-55 has good and replicated evidence for structural and construct validity and internal consistency. Health-Related Quality of Life Measure for Children with Epilepsy (CHEQoL) has both child and parent-reported versions and good evidence of content, structural, and construct validity.
SIGNIFICANCE: This review identified two leading candidate epilepsy-specific PROMs for measuring health-related quality of life in children. Establishing evidence of the responsiveness of PROMs is a priority to help the interpretation of meaningful change scores.
