Test/retest reliability and inter-rater agreement of the Quality of Upper Extremities Skills Test (QUEST) for older children with acquired brain injuries.

Test/retest reliability and inter-rater agreement was established on the Quality of Upper Extremities Skills Test (QUEST) for 16 children between 6 and 16 years of age who had an acquired brain injury. Performance on the QUEST was videotaped for the purpose of scoring, and some modifications were made to the administration and scoring of the assessment. Intra-class correlation indicated high agreement for test/retest reliability (0.90 to 0.95), and inter-rater reliability (0.84 to 0.94) across all subtests. The findings are discussed in terms of ongoing test refinements and the extension of the original age range and diagnostic group for which the test was designed.
