Reliability and Validity of the Japanese Version of the Physical Activity Questionnaire for Older Children

摘要

Objectives: This study aimed to examine the reliability and validity of the Japanese version of the Physical Activity Questionnaire for Older Children (PAQ-C) in Japanese children aged 9 to 12?years. Methods: A total of 210 children aged between 9 and 12?years participated. Internal consistency and test-retest reliability were evaluated using Cronbach alpha coefficient and intraclass correlation coefficient (ICC), respectively. Validity was evaluated using athletic competence (AC), self-efficacy (SE), body mass index (BMI), body fat percentage (%BF), cardiovascular fitness (CVF), and World Health Organization Health Behavior in School-aged Children (WHO HBSC) physical activity questionnaire. Results: Internal consistency was acceptable (alpha?=?0.80) and test-retest reliability showed excellent agreement (ICC?=?0.83). The PAQ-C score was significantly correlated with AC ( r ?=?0.41), SE ( r ?=?0.65), %BF ( r ?=?0.19), and CVF ( r ?=??0.32). The PAQ-C score of the active group classified by the WHO HBSC physical activity questionnaire (mean score ± standard deviation [SD] = 3.03 ± 0.57) was significantly higher than that of the inactive group (mean score ± SD = 2.27 ± 0.63, P ?&?.01). Conclusions: The PAQ-C had acceptable reliability and validity. The PAQ-C is a useful instrument to evaluate physical activity for Japanese children aged 9 to 12?years.
