METHODS: Our study involves eight stages: (1) systematic review of psychometric properties of existing PA questionnaires for children and adolescents; (2) development of the GAC-PAQ (first version); (3) content validity assessment with global experts; (4) cognitive interviews with children/adolescents and parents in all 14 countries; (5) development of a revised GAC-PAQ; (6) development and adaptation of the questionnaire app (application); (7) pilot-test of the app-based GAC-PAQ; and, (8) main study with a stratified, sex-balanced and urban/rural-balanced sample of 500 children/adolescents and one of their parents/guardians per country. Participants will complete the GAC-PAQ twice to assess 1-week test-retest reliability and wear an ActiGraph wGT3X-BT accelerometer for 9 days to test concurrent validity. To assess convergent validity, subsamples (50 adolescents/country) will simultaneously complete the PA module from existing international surveys.
BACKGROUND: Approvals from research ethics boards and relevant organisations will be obtained in all participating countries. We anticipate that the GAC-PAQ will facilitate global surveillance of PA in children/adolescents. Our project includes a robust knowledge translation strategy sensitive to social determinants of health to inform inclusive surveillance and PA interventions globally.
方法:我们的研究涉及八个阶段:(1)对儿童和青少年现有PA问卷的心理测量特性进行系统审查;(2)GAC-PAQ(第一版)的开发;(3)与全球专家进行内容有效性评估;(4)对所有14个国家/地区的儿童/青少年和父母进行认知访谈;(5)开发经修订的GAC-PAQ-应用;(基于(8)主要研究采用分层,每个国家500名儿童/青少年及其父母/监护人的性别平衡和城市/农村平衡样本。参与者将两次完成GAC-PAQ以评估1周的重测可靠性,并佩戴ActiGraphwGT3X-BT加速度计9天以测试并发有效性。为了评估收敛有效性,子样本(50名青少年/国家)将同时完成现有国际调查的PA模块。
背景:将在所有参与国家获得研究伦理委员会和相关组织的批准。我们预计GAC-PAQ将促进对儿童/青少年PA的全球监测。我们的项目包括对健康的社会决定因素敏感的强大知识翻译策略,为全球包容性监测和PA干预提供信息。
