| 1 | Validation of the Physical Activity Questionnaire for Older Children(PAQ-C) among Chinese Children显示文摘Objective This study initially validates the Chinese version of the Physical Activity Questionnaire for Older Children(PAQ-C), which has been identified as a potentially valid instrument to assess moderate-to-vigorous physical activity(MVPA) in children among diverse racial groups. Methods The psychometric properties of the PAQ-C with 742 Hong Kong Chinese children were assessed with the scale's internal consistency, reliability, test-retest reliability, confirmatory factory analysis(CFA) in the overall sample, and multistep invariance tests across gender groups as well as convergent validity with body mass index(BMI), and an accelerometry-based MVPA. Results The Cronbach alpha coefficient(α=0.79), composite reliability value(ρ=0.81), and the intraclass correlation coefficient(α=0.82) indicate the satisfactory reliability of the PAQ-C score. The CFA indicated data fit a single factor model, suggesting that the PAQ-C measures only one construct, on MVPA over the previous 7 days. The multiple-group CFAs suggested that the factor loadings and variances and covariances of the PAQ-C measurement model were invariant across gender groups. The PAQ-C score was related to accelerometry-based MVPA(r=0.33) and inversely related to BMI(r=-0.18). Conclusion This study demonstrates the reliability and validity of the PAQ-C in Chinese children. | WANG Jing Jing BARANOWSKI Tom LAU WC Patrick CHEN Tzu An PITKETHLY Amanda Jane | 2016 | Biomedical and Environmental Sciences2016，29，3： | 7 |
