Validity and reliability of the Wood Motor Success Screening Tool in a special physical education learning laboratory.

The purpose of this study was to estimate the concurrent validity and test-retest reliability of the Wood Motor Success Screening Tool. Participants were 66 children with learning and behavioral disabilities (44 boys and 22 girls; M of age= 7.6 yr.; SD of age= 1.8 yr.). The concurrent validity was checked using the Bruininks-Oseretsky Test of Motor Proficiency-Short Form as the criterion measure. A Pearson product-moment correlation of .84 (p< .01), a sensitivity index of .88, and a specificity index of .64 were found for estimating the concurrent validity. The test-retest reliability was checked using scores on the Wood Motor Success Screening Tool administered twice within a week. An intraclass correlation coefficient of .93 from the one-way analysis of variance was found for estimating the test-retest reliability. These results indicated that this test is valid and reliable for assessing young children.
