Abstract

The Test of Gross Motor Development is used to identify children's level of motor proficiency, specifically to detect motor delays. This study aimed to translate the TGMD-3 items and assess reliability and content and construct validity for the TGMD-3 in Brazil. A cross-cultural translation was used to generate a Brazilian Portuguese version of the TGMD-3. The validation process involved 33 professionals and 597 Brazilian children (ages 3-10) from the five main geographic regions of Brazil. The results confirmed language clarity and pertinence, as well as face validity of the TGMD-3. High intrarater (.60 to .90) and interrater (.85 to .99) reliability was evident, and test-retest temporal stability was confirmed (locomotor .93; ball skills .81). Adequate internal consistency was present for the skills-to-test and subtests correlations (TGMD-3-BR: α .74; locomotor skills: α .63; ball skills: α .76) and performance-criteria-to-test and -subtest correlations (TGMD-3: α .93; locomotor skills: .90; ball skills: .88). Confirmatory factor analysis supported the construct validity of a two-factor model (RMSEA = .04, 90% confidence interval: .03 to .05; CFI = .94; NFI = .91; TLI = .92; GFI = .94; AGFI = .92). The TGMD-3 is a valid and reliable instrument for Brazilian children.
