Resumen de A Quantitative Approach to Movement Skill Assessment for Children With Mental Retardation

Deborah R. Shapiro, Joonkoo Yun

• This study examined the psychometric properties of Ulrich¿s (1988) Actual Physical Competence Scale for children with mental retardation. A total of 139 children with MR, 7 to 13 years of age participated. Confirmatory factor analyses indicated that a multidimensional model of skill assessment captures the motor performance of those with MR more accurately than a unidimensional model. Indices of goodness of fit for the multidimensional model were GFI = .91, RMSEA = .09, (c2/df) = 2.15, and CFI = .93. Test-retest reliability and internal consistency for the total test battery was ICC = .91 and a = .62, respectively. When evaluating movement skills of children with mental retardation, a multidimensional model incorporating both locomotor and object control skills is recommended.
