BackgroundThe tools used to assess motor performance in children with low vision often have no validity and reliability data concerning this population and use non-standardized modifications. Adaptations of these tools could help to identify motor problems and mitigate their effects.AimTo assess aspects of validity and reliability in an adaptation of the Movement ABC-2 Test (MABC-2) for children with low vision.Methods and proceduresThe research was undertaken in two stages: 1) application of the original MABC-2 to 10 children with low vision, adaptation and pilot test; 2) administration and re-administration of the adapted MABC-2 in 30 children with low vision. Inter-rater reliability and test-retest reliability were assessed with an intraclass correlation coefficient and Kappa index; internal consistency was assessed with Cronbach's alpha.Outcomes and resultsSubstantial to almost perfect inter-rater reliability was found between the component standard scores and a reasonable to excellent concordance rate in the classification of movement difficulty. The adapted tool has moderate internal consistency.Conclusions and implicationsThe adapted MABC-2 Test has improved the assessment of motor performance in children with low vision.
