BACKGROUND
Pediatricians' clinical practice and health interventions in youths require instruments with adequate psychometric properties to assess physical activity (PA), sedentary behaviors (SB), and their subdomains.
OBJECTIVE
To assess the psychometric properties of the Children and Adolescents Physical Activity and Sedentary-Questionnaire (CAPAS-Q) in healthy French children and adolescents.
METHODS
The CAPAS-Q has been developed through a rigorous collective procedure and consists of a 31 items self-administered questionnaire evaluating children's 7-day PA and SB dimensions and subdomains. Participants ( = 103, aged 8-18 years old) completed the questionnaire twice (7 days apart) and wore an ActiGraph GT3X + accelerometer for 7 days. Anthropometric measurements and body composition were assessed.
RESULTS
Cronbach alpha for PA and SB dimensions were 0.71 and 0.68, respectively. Reproducibility was found moderate to good, with Lin's coefficients of 0.69 and 0.68 for PA and SB dimensions, respectively. Reproducibility was higher for adolescents compared to children. PA dimension was positively correlated with moderate PA, vigorous PA, moderate to vigorous PA, and total PA times and negatively correlated with SB time ( < 0.05). SB dimension and screen time were positively correlated with SB time and negatively correlated with LPA, MPA, MVPA, and total PA times ( < 0.05). Spearman correlation coefficients were fair to moderate, ranging between 0.23-0.45.
CONCLUSION
The CAPAS-Q proposes a reliable and valid evaluation of French children and adolescents' PA and SB, providing clinicians with potential intervention levels to improve youth movement behaviors.
背景
儿科医生在青少年中的临床实践和健康干预需要具有足够心理计量特性的工具来评估身体活动（PA）、久坐行为（SB）及其子领域。
目的
评估儿童和青少年身体活动和久坐行为问卷（CAPAS-Q）在健康法国儿童和青少年中的心理计量特性。
方法
CAPAS-Q 是通过严格的集体程序开发的，由 31 个项目组成的自我管理问卷，评估儿童 7 天的 PA 和 SB 维度和子领域。参与者（n=103，年龄 8-18 岁）两次完成问卷（相隔 7 天），并佩戴 ActiGraph GT3X+加速度计 7 天。进行了人体测量和身体成分评估。
结果
PA 和 SB 维度的克朗巴赫α系数分别为 0.71 和 0.68。重现性被发现为中度到良好，Lin 系数分别为 PA 和 SB 维度的 0.69 和 0.68。青少年的重现性高于儿童。PA 维度与中等强度 PA、剧烈 PA、中等到剧烈 PA 和总 PA 时间呈正相关，与 SB 时间呈负相关（<0.05）。SB 维度和屏幕时间与 SB 时间呈正相关，与 LPA、MPA、MVPA 和总 PA 时间呈负相关（<0.05）。Spearman 相关系数为 0.23-0.45，范围从一般到中等。
结论
CAPAS-Q 提供了对法国儿童和青少年 PA 和 SB 的可靠和有效的评估，为临床医生提供了潜在的干预水平，以改善青少年的运动行为。
