Psychometric evaluation of the pictorial scale of perceived movement skill competence in Chinese children: An item response theory analysis
Aim
This study aimed to investigate the psychometric characteristics of the Pictorial Scale of Perceived Movement Skill Competence (PMSC) in Chinese children, utilizing the principles of item response theory (IRT).
Methods
A total of 284 children (147 boys), aged 4–10 years (Mage = 7.39, SD = 2.18), from four schools were recruited for testing, adhering to the principle of random sampling. The Rasch model was applied to evaluate the rating scale validity, local independence, scale dimensionality, person and item fit statistics, and differential item functioning (DIF).
Results
(1) The rating scale validity was confirmed by the monotonically increasing trend in both average item difficulty measures and Andrich thresholds. (2) However, the observation that standardized residual correlations for all items remained below 0.3 unequivocally confirmed the presence of local independence among the variables. (3) The scale's dimensions were substantiated, with Rasch measures explaining 40.6% of total variance, exceeding the 40% threshold. Additionally, the first contrast had an eigenvalue of 1.8 and explained 8.80% of the variance, both exceeding the minimum 3:1 ratio. Consequently, the unidimensionality assumption of the item was supported. (4) Person and item fit statistics indicated requisite reliability and separation, with all achieving suitable infit and outfit measures, and point-biserial correlations exceeding 0.55. (5) Regarding gender DIF, it was observed that the majority of items did not exhibit statistically significant gender DIF effects (p > 0.05) except item 8 (Bounce a ball, t = −2.74, p < 0.01, DIF = −0.51).
Conclusion
Rasch analysis revealed that the instrument exhibited strong scale validity among Chinese children, adhering to the Rasch model's unidimensionality and local independence principles, with robust person and item reliability and separation. All items demonstrated a good fit. Additionally, the significant gender difference in item 8 (Bounce a ball) warrants further consideration. In conclusion, PMSC is suitable for assessing the PMSC of Chinese children.
期刊介绍：
Child: care, health and development is an international, peer-reviewed journal which publishes papers dealing with all aspects of the health and development of children and young people. We aim to attract quantitative and qualitative research papers relevant to people from all disciplines working in child health. We welcome studies which examine the effects of social and environmental factors on health and development as well as those dealing with clinical issues, the organization of services and health policy. We particularly encourage the submission of studies related to those who are disadvantaged by physical, developmental, emotional and social problems. The journal also aims to collate important research findings and to provide a forum for discussion of global child health issues.
