A dynamic balance measure for persons with severe and profound mental retardation

The present study's purpose was to probe into the reliability and validity measurement of dynamic balance for individuals with IQs below 29. The 91 subjects were asked to complete the Papcsy-DePaepe test and the Bruininks test according to each test's protocol. Correlations of odd-even scores produced a reliability of .98 for the Papcsy-DePaepe test. Concurrent validity was indicated by a Pearson product-moment correlation of .64 between the two tests. Subsequent 3 x 2 x 2 multivariate analyses of variance confirmed a significant difference between the two tests and that retardation was associated with balance performance although age and gender were not.
