Measurement invariance of TGMD-3 in children with and without mental and behavioral disorders.

摘要: This study evaluated whether the Test of Gross Motor Development 3 (TGMD-3) is a reliable tool to compare children with and without mental behavioural disorders across gross motor skill domains. A total 1075 (aged 3-11 years), 98 977 (typically developing), were included in analyses. The TGMD-3 evaluates fundamental skills two domains: locomotor ball skills. Two independent testers simultaneously observed children’s performances (agreement over 95%). Each child completed one practice then formal trials. Scores recorded only during formal trials. Multigroup Confirmatory Factor Analysis tested assumption measurement invariance disability groups. According magnitude changes Root Mean Square Error Approximation Comparative Fit Index between nested models, groups was valid. Loadings manifest indicators on significant (p < .001) both Item Response Theory analysis showed good reliability results full latent traits. present study confirmed factorial structure demonstrated its feasibility normally developing disorders. These findings provide new opportunities for understanding effect specific intervention strategies this population.
