Background and Aim: The aim was to determine the validity and reliability of the Perceived Movement Skill Competence scales which are aligned with the 2nd and 3rd versions of Test of Gross Motor Development, and the active play skills for Iranian young children.
Materials and Methods: Of a total sample of 314 children aged 4-8 years (M age=6.1 years, SD=1.1), a random sample of 74 were recruited for face validity. The data from the remaining sample of 240 were used to establish construct validity using Bayesian Structural Equation Modelling. The data from a second random subsample of 126 children were used to investigate PMSC reliability using ordinal alpha coefficients and intra-class correlations (ICC).
Results: The majority of children correctly identified the skills and understood most of the pictures. Internal consistency was very good (from 0.81 to 0.95) for all scales and subscales. Test-retest reliability was excellent with ICC values above 0.85. For construct validity, the initial hypothesized models for three-factor (i.e. locomotor, object control and play skills) and two-factor (i.e. locomotor and object control) models showed reasonable fit.
Conclusion: The pictorial scales for Perceived Movement Skill Competence are valid and reliable for Iranian young children.
