Objective:
This study is aimed to report the development, the reliability and validity of the Chinese Children Physical Activity Questionnaire (CCPAQ) which was designed for the assessment of physical activity pattern in young population in China.
Methods:
The CCPAQ was administered for two times in 119 children (mean age 13.1 ± 2.4 years; boys 47%) to examine reliability by using intraclass correlation coefficients. Validity was determined in 106 participants by agreement with the CCPAQ measures and the objective method, the ActiGraph accelerometer. Data on physical activity pattern including time spent on different intensities and total physical activity, sedentary behavior as well as physical activity energy expenditure were used to assess the validity with Spearman's correlation coefficient and the Bland-Altman plots.
Results:
The reliability coefficient of the CCPAQ ranged from 0.63-0.93 (Intra-class correlation coefficient). Spearman's correlation coefficient for validity of time spent on total physical activity and sedentary behavior were all 0.32 (P < 0.001), and for physical activity energy expenditure was 0.58 (P < 0.001). Time spent on moderate-to-vigorous physical activity and light physical activity showed a relatively low correlation with the accelerometer (rho = 0.20, P = 0.040; rho = 0.19, P = 0.054).
Conclusion:
The CCPAQ appears to be a promising and feasible method to assess physical activity pattern in Chinese children.
