A questionnaire on explanatory variables for each behavior of the 24-h movement behaviors (i.e., physical activity, sedentary behavior, sleep) was developed based on three levels of the socio-ecological model, i.e., the intrapersonal level, interpersonal level and the physical environmental level. Within these levels, different constructs were questioned, i.e., autonomous motivation, attitude, facilitators, internal behavioral control, self-efficacy, barriers, subjective norm, social modeling, social support, home environment, neighborhood, and work environment. The questionnaire was tested for test-retest reliability (i.e., intraclass correlation (ICC)) for each item and internal consistency for each construct (i.e., Cronbach's Alpha Coefficient) among a group of 35 healthy adults with a mean age of 42.9 (±16.1) years. The total questionnaire contained 266 items, consisting of 14 items on general information, 70 items on physical activity, 102 items on sedentary behavior, 45 items on sleep and 35 items on the physical environment. Seventy-one percent of the explanatory items showed moderate to excellent reliability (ICC between 0.50 and 0.90) and a majority of constructs had a good homogeneity among items (Cronbach's Alpha Coefficient ≥ 0.70). This newly developed and comprehensive questionnaire might be used as a tool to understand adults' 24-h movement behaviors.
一个关于 24 小时运动行为（即体力活动、久坐行为、睡眠）每个行为的解释变量的问卷，是基于社会生态模式的三个层次，即个体内部、人际和物理环境水平来制定的。在这些层次中，询问了不同的结构，即自主动机、态度、促进因素、内部行为控制、自我效能、障碍、主观规范、社会模仿、社会支持、家庭环境、邻里环境和工作环境。该问卷在一组 35 名健康成年人中进行了测试，这些成年人的平均年龄为 42.9（±16.1）岁，用于测试每个项目的重测信度（即组内相关系数（ICC））和每个结构的内部一致性（即克朗巴赫 α系数）。总问卷包含 266 个项目，包括 14 个一般信息项目、70 个体力活动项目、102 个久坐行为项目、45 个睡眠项目和 35 个物理环境项目。71%的解释性项目具有中等至极好的可靠性（ICC 在 0.50 到 0.90 之间），大多数结构的项目之间具有良好的同质性（克朗巴赫 α系数≥0.70）。这个新开发的综合性问卷可能被用作理解成年人 24 小时运动行为的工具。
