[Purpose] To describe our newly developed Sedentary Behavior and Light-Intensity Physical Activity Questionnaire and examine its reliability and validity. [Participants and Methods] We identified and selected self-reported items through a literature review and interviews with 11 inactive individuals. Thirty-one individuals with lower limb prostheses and an expert panel assessed the content validity of the integrated items and identified 17 items. Patients who had undergone lower limb surgeries were regarded as inactive individuals, and 112 patients completed the questionnaire twice for test-retest reliability and wore an accelerometer for criterion validity. The ethics committee of Kyushu University approved this study (2019-126 and 2019-273). [Results] Item analysis was revised to the Sedentary Behavior and Light-Intensity Physical Activity Questionnaire-10 (six light-intensity physical activity and four sedentary behavior items) because of the floor effect. The test-retest correlation coefficient showed high reliability. Moderate to weak correlation coefficient was observed between the questionnaire and accelerometer (light-intensity physical activity: 0.43 and sedentary behavior: 0.20), and the Bland-Altman plots indicated no bias. [Conclusion] The Sedentary Behavior and Light-Intensity Physical Activity Questionnaire-10 had acceptable validity and reliability among inactive individuals and it could be used for studying light-intensity physical activity.
[目的]描述我们新开发的久坐行为和低强度体力活动问卷，并检验其信效度。[参与者与方法]我们通过文献综述以及对11名缺乏运动的个体进行访谈，识别并筛选出自我报告项目。31名下肢假肢佩戴者和一个专家小组评估了综合项目的内容效度，并确定了17个项目。接受过下肢手术的患者被视为缺乏运动的个体，112名患者完成了问卷两次以进行重测信度检验，并佩戴加速度计以进行效标效度检验。九州大学伦理委员会批准了本研究（2019 - 126和2019 - 273）。[结果]由于地板效应，项目分析后修订为久坐行为和低强度体力活动问卷 - 10（六个低强度体力活动项目和四个久坐行为项目）。重测相关系数显示出高信度。问卷与加速度计之间观察到中度至弱相关系数（低强度体力活动：0.43，久坐行为：0.20），且Bland - Altman图显示无偏差。[结论]久坐行为和低强度体力活动问卷 - 10在缺乏运动的个体中具有可接受的效度和信度，可用于研究低强度体力活动。
