Abstract
Purpose: This study aimed to vet the measurement properties of Brief-BESTest scores in children, adolescents, and youth with visual impairment and blindness (YVI). Methods: A cross-sectional sample of YVI (N = 101) completed the Brief-BESTest, a modified version of the Y-Balance Test, the 360-degree turn test, bipedal quiet stance, and Activity-Specific Balance Confidence Scales. Thirty-seven YVI completed test-retest of the Brief-BESTest using a one-year interval. Using classical test theory, various forms of total and item-level Brief-BESTest score reliability and validity were investigated in YVI. Results: All inter-rater reliability coefficients were ≥ .80. When considering the eight items of the Brief-BESTest, 27 of the 28 possible correlations were statistically significant (p<.05). Various internal consistency and item difficulty results were strong. When taking total Brief-BESTest scores and their association with the complementary balance tasks/metrics into account, 11 of 13 associations were statistically significant (p<.05) providing strong convergent validity evidence. Being multimorbid and degree of vision significantly predicted total Brief-BESTest scores (p<.001) suggesting construct (i.e. known groups) validity. Numerous test-retest results (e.g. coefficients, limits of agreement) following the one-year interval were indicative of score stability. Conclusion: Practitioners and researchers should have confidence in, and consider adopting, the Brief-BESTest to examine multidimensional balance in YVI.
