AIM: To identify and appraise the quality of studies that primarily assessed the measurement properties of English language versions of multidimensional patient-reported outcome measures (PROMs) when evaluated with children with neurodisability, and to summarize this evidence. METHOD: MEDLINE, Embase, PsycINFO, CINAHL, AMED, and the National Health Service Economic Evaluation Database were searched. The methodological quality of the papers was assessed using the COnsensus-based Standards for selection of health Measurement INstruments checklist. Evidence of content validity, construct validity, internal consistency, test-retest reliability, proxy reliability, responsiveness, and precision was extracted and judged against standardized reference criteria. RESULTS: We identified 48 studies of mostly fair to good methodological quality: 37 papers for seven generic PROMs (CHIP, CHQ, CQoL, KIDSCREEN, PedsQL, SLSS, and YQOL), seven papers for two chronic-generic PROMs (DISABKIDS and Neuro-QOL), and four papers for three preference-based measures (HUI, EQ-5D-Y, and CHSCS-PS). INTERPRETATION: On the basis of this appraisal, the DISABKIDS appears to have more supportive evidence in samples of children with neurodisability. The overall lack of evidence for responsiveness and measurement error is a concern when using these instruments to measure change, or to interpret the findings of studies in which these PROMs have been used to assess change.
