PURPOSE The current study examined the validity of scores from the sitting time item on the International Physical Activity Questionnaire-Short Form (IPAQ-SF) in a sample of persons with multiple sclerosis (MS). METHOD Persons with MS were recruited through the distribution of printed letters to a random sample of 1,000 persons from the North American Research Committee on MS registry. Two hundred ninety-five persons with MS were interested and volunteered to wear an ActiGraph accelerometer for a 7-day period and complete a battery of questionnaires that included the IPAQ-SF and Godin Leisure-Time Exercise Questionnaire over this period of time. RESULTS IPAQ-SF sitting time scores were consistently and moderately correlated with all of the sedentary behavior metrics from the accelerometer (range of r between .295 and .431), and the correlations were stronger than those between self-reported physical activity and sedentary metrics from the accelerometer (range of r between -.087 and .163). The correlations between IPAQ-SF sitting time scores with the accelerometer-derived sedentary behavior metrics were still statistically significant in the analyses controlling for physical activity (range of parametric correlations between .281 and .411). CONCLUSIONS The correlation analysis indicated consistent, moderate correlations between IPAQ-SF sitting time scores and device-measured estimates of both the volume and pattern of sedentary behavior, and the correlations were (a) stronger than those for self-reported physical activity and (b) independent of self-reported physical activity. Such results provide initial evidence for the validity of inferences from IPAQ-SF sitting time scores as an overall measure of sedentary behavior in persons with MS.

国际体育活动问卷——多发性硬化症简表中坐下时间分数的有效性。

目的 本研究在多发性硬化症 (MS) 患者样本中检查了国际体育活动问卷简表 (IPAQ-SF) 中坐时间项目分数的有效性。方法 通过向北美 MS 注册研究委员会的 1,000 人随机样本分发印刷信件来招募 MS 患者。295 名 MS 患者对此感兴趣并自愿佩戴 ActiGraph 加速度计 7 天,并在这段时间内完成一系列问卷调查,其中包括 IPAQ-SF 和 Godin 休闲时间锻炼问卷。结果 IPAQ-SF 坐下时间分数与来自加速度计的所有久坐行为指标一致且适度相关(r 范围在 0.295 和 0.431 之间),并且相关性强于自我报告的身体活动和来自加速度计的久坐指标之间的相关性(r 范围在 -.087 和 .163 之间)。在控制身体活动的分析中,IPAQ-SF 坐下时间分数与加速度计得出的久坐行为指标之间的相关性仍然具有统计学意义(参数相关性范围介于 0.281 和 0.411 之间)。结论 相关性分析表明,IPAQ-SF 坐下时间得分与设备测量的久坐行为量和模式估计值之间存在一致的中度相关性,并且相关性(a)强于自我报告的身体活动的相关性和(b) ) 独立于自我报告的身体活动。这些结果为 IPAQ-SF 静坐时间评分作为 MS 患者久坐行为的整体衡量指标的推论的有效性提供了初步证据。(PsycINFO 数据库记录 (c) 2019 APA,保留所有权利)。
