Sedentary behavior is related to obesity, but measures of sedentary behaviors are lacking for adults. The purpose of this study was to examine the reliability and validity of the Sedentary Behavior Questionnaire (SBQ) among overweight adults.
Participants were 49 adults for the 2 week test-retest reliability study (67% female, 53% white, mean age = 20) and 401 overweight women (mean age = 41, 61% white) and 441 overweight men (mean age = 44, 81% white) for the validity study. The SBQ consisted of reports of time spent in 9 sedentary behaviors. Outcomes for validity included accelerometer measured inactivity, sitting time (International Physical Activity Questionnaire), and BMI. Intraclass correlation coefficients (ICCs) assessed reliability and partial correlations assessed validity.
ICCs were acceptable for all items and the total scale (range = .51-.93). For men, there were significant relationships of SBQ items with IPAQ sitting time and BMI. For women, there were relationships between the SBQ and accelerometer inactivity minutes, IPAQ sitting time, and BMI.
The SBQ has acceptable measurement properties for use among overweight adults. Specific measures of sedentary behavior should be included in studies and population surveillance.
久坐行为与肥胖有关，但缺乏针对成年人久坐行为的测量方法。本研究旨在检验久坐行为问卷（SBQ）在超重成年人中的信度和效度。
在为期 2 周的重测信度研究中，有 49 名成年人（67%为女性，53%为白人，平均年龄为 20 岁）和 401 名超重女性（平均年龄为 41 岁，61%为白人）和 441 名超重男性（平均年龄为 44 岁，81%为白人）参加了有效性研究。SBQ 由 9 种久坐行为的报告时间组成。有效性的结果包括加速度计测量的不活动时间、坐姿时间（国际体力活动问卷）和 BMI。组内相关系数（ICCs）评估信度，偏相关评估效度。
所有项目和总量表的 ICC 均为可接受（范围为.51-.93）。对于男性，SBQ 项目与 IPAQ 坐姿时间和 BMI 存在显著关系。对于女性，SBQ 与加速度计不活动分钟数、IPAQ 坐姿时间和 BMI 之间存在关系。
SBQ 对超重成年人具有可接受的测量特性。在研究和人群监测中应包括对久坐行为的具体测量。
