“…Unfortunately, despite their report of analyses focused on the identification of an age or sex difference in PMC-C scores, Dreisk€ amper et al (2018) did not report evidence of measurement invariance or lack of DIF of children's responses to the PMC-C as a function of these two characteristics. More generally, although the role of a variety of common attributes or characteristics (e.g., age, body mass-index or BMI, physical activity/sport involvement and sex) are frequently assessed in studies examining children's perceived motor competence (e.g., Carcamo-Oyarzun et al, 2020;Clark et al, 2018;Estevan et al, 2018;Morano et al, 2020), there is no current evidence that the PMC-C can reliably (i.e., without biases) investigate associations between perceived motor competencies and these characteristics. Previous research has reported mean differences in perceived motor competence as a function of: (a) age (i.e., older children tended to present significantly higher scores than younger children; e.g., Estevan et al, 2018;Morano et al, 2020); (b) BMI (i.e., children having higher BMI tended to present lower scores than those with a lower BMI; e.g., Carcamo-Oyarzun et al, 2020); (c) physical activity/sport involvement (i.e., physically active children tended to score higher than inactive children; e.g., Famelia et al, 2018); and (d) sex (i.e., boys tended to present significantly higher scores than girls; e.g., Carcamo-Oyarzun et al, 2020;Clark et al, 2018;Estevan et al, 2018;Morano et al, 2020).…”
