Abstract：
BACKGROUND: Global surveillance of physical activity (PA) of children and adolescents with questionnaires is limited by the use of instruments developed in high-income countries (HICs) lacking sociocultural adaptation, especially in low- and middle-income countries (LMICs); under-representation of some PA domains; and omission of active play, an important source of PA. Addressing these limitations would help improve international comparisons, and facilitate the cross-fertilisation of ideas to promote PA. We aim to develop and assess the reliability and validity of the app-based Global Adolescent and Child Physical Activity Questionnaire (GAC-PAQ) among 8-17 years old in 14 LMICs and HICs representing all continents; and generate the \'first available data\' on active play in most participating countries.
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.

摘要：
背景：通过问卷调查对儿童和青少年的身体活动（PA）进行全球监测，由于使用缺乏社会文化适应的高收入国家（HIC）开发的工具而受到限制，特别是在低收入和中等收入国家(LMICs)；一些PA领域代表性不足；以及省略积极的游戏，PA的重要来源。解决这些限制将有助于改善国际比较，并促进思想的交叉受精，以促进PA。我们的目标是开发和评估基于应用程序的全球青少年和儿童体育活动问卷（GAC-PAQ）的可靠性和有效性，该问卷适用于代表各大洲的14个LMIC和HIC的8-17岁儿童；并生成有关大多数参与国家的积极活动的“第一个可用数据”。
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。
