Physical literacy in children: Exploring the construct validity of a multidimensional physical literacy construct

Physical literacy (PL) is highlighted as a construct that can positively impact physical activity (PA). Measurement methods and definitions for PL exist, but vary between research groups. This variation affects the ability to compare research findings. The purpose of this study was to assess the construct validity of PL in children. PL was operationalised according to Whitehead’s (2001) definition, comprising confidence, motivation, physical competence, and knowledge and understanding. Participants (n = 1073; mean age 10.86 ± 1.20 years: 53% male) were measured on: (i) confidence (Physical Activity Self-Efficacy Scale; Bartholomew et al., 2006), (ii) motivation (Behavioural Regulation in Exercise-Adapted; Sebire et al., 2013), (iii) physical competence (health-related fitness: 20 m shuttle run, back-saver sit-and-reach, handgrip strength, plank); balance (Bruininks-Oseretsky Test of Motor Proficiency 2; Bruininks, 2005); object-control and locomotor skills (Test of Gross Motor Development-3rd edition (TGMD-3); Ulrich, 2016); and (iv) knowledge and understanding (PA and sedentary guidelines). Confirmatory factor analysis (CFA) was conducted to analyse the factor structure of PL. The best-fitting model (χ2 = 209.8, df = 99, p
