Bilateral coordination and motor sequencing in Brazilian children: preliminary construct validity and reliability analysis.
This study examined aspects of reliability and validity of the bilateral coordination and motor sequencing items of the Assessment of Motor Coordination and Dexterity (AMCD) for Brazilian children ages 4, 6 and 8 years old. The AMCD aims to identify children with developmental coordination disorder (DCD). A total of 84 children were evaluated. Among the 35 items piloted, all but one presented interrater reliability above 0.80 and 16 (45.7%) items presented intraclass correlation coefficient over 0.60 for test-retest reliability. Most items were sensitive to age difference and only items involving ball handling exhibited significant gender differences. As a result, this section of the AMCD could be reduced to the 20 items that were found to be reliable and more discriminative for age-related differences. This study advances on the development of the AMCD, but a limitation was the noninclusion of children with DCD. Future research should investigate whether the selected items are useful in differentiating the motor skills of children with and without coordination problems.
