Abstract

With recent revisions, the evaluation of the reliability and validity of the Test of Gross Motor Development-3rd edition (TGMD-3) is necessary. The TGMD-3 was administered to 807 children (M age = 6.33 ± 2.09 years; 52.5% male). Reliability assessments found that correlations with age were moderate to large; ball skills had a higher correlation (r =.47) compared with locomotor skills (r =.39). Internal consistency was very high in each age group and remained excellent for all racial/ethnic groups and both sexes. Test-retest reliability had high ICC agreements for the locomotor (ICC = 0.97), ball skills (ICC = 0.95), and total TGMD-3 (ICC = 0.97). For validity measures, the TGMD-3 had above acceptable item difficulty (range = 0.43-0.91) and item discrimination values (range = 0.34-0.67). EFA supported a one-factor structure of gross motor skill competence for the TGMD-3 with 73.82% variance explained. CFA supported the one-factor model (Χ²(65) = 327.61, p <.001, CFI =.95, TLI =.94, RMSEA =.10), showing acceptable construct validity for the TGMD-3. Preliminary results show the TGMD-3 exhibits high levels of validity and reliability, providing confidence for the usage and collection of new norms.
