| Abstract: | Validity and reliability of the Bruininks-Oseretsky Test of Motor Proficiency-Short Form were examined through factor analysis, differences in motor proficiency among age groups, and internal consistency. The sample was comprised of 194 children (96 boys and 98 girls) of ages 6 to 11 years. A principal factor analysis solution with varimax rotation produced four factors: Gross and Fine Motor Skills, Eye-Hand Coordination, Balance-Coordination and Speed, and Visual-motor Coordination. The loadings of these factors partially supported the theoretical work of Bruininks. Univariate analysis of variance showed significant differences between age groups either for each single item or for the total score. Correlation coefficients between single-item and total short form were all significant, although some values were relatively small. These results provided positive support for the construction and reliability of the test. |
