Abstract
Aim
To develop the Physical Literacy Profile Questionnaire (PLP-Quest) for children, adolescents, and young adults with disabilities and to assess its measurement properties.
Method
The PLP-Quest was developed based on the physical literacy framework proposed by the Australian Sports Commission, and following the Consensus-based Standards for the selection of health Measurement Instruments (COSMIN) criteria for instrument development. After development, the following PLP-Quest measurement properties were investigated: content validity, structural validity, internal consistency and test-retest reliability.
Results
All PLP-Quest items were considered relevant and comprehensive by 50 caregivers and 50 health professionals. In structural validity analysis, with 109 responses, two items were removed, resulting in a final set of 22 items in PLP-Quests’ final version. There was predominance of a single factor in the principal component analysis, confirming unidimensionality. Cronbach’s alpha analysis showed that the instrument had good internal consistency (α = 0.93). The analysis of the intraclass correlation coefficient (ICC) showed that the instrument had good test-retest reliability (ICC= 0.92, 95% CI: 0.87-0.96).
Interpretation
Preliminary assessments of the measurement properties of the PLP-Quest indicate that this instrument has the potential to assess physical literacy in children, adolescents, and young adults with disabilities.
