Using Rasch modeling to investigate the construct of motor competence in early childhood

The study shows item and person homogeneity within a validated motor score, using 12 items of the MOT 4-6. Thus, it provides evidence of a single latent construct (i.e., motor competence), which underlies the performance of motor skills in early childhood. Furthermore, it shows that counting the number of successful trails may be less suitable as a scoring system in motor competence assessment. Present findings also support the use of validated composite scores in motor assessment.
