Abstract
An investigation in a randomized population-based Swedish study with 564 participants aged 18-80 years showed that mean physical activity levels obtained using short message service (SMS) by means of cell phones (n = 171) were equal to corresponding levels obtained when sending identical questions by web (n = 182) or paper (n = 211). The response rates were similar for the SMS, web and paper groups.
摘要
一项在瑞典进行的基于随机人群的研究，共有 564 名 18-80 岁的参与者，研究结果显示，使用手机短信服务（SMS）获取的平均体力活动水平（n = 171）与通过网络（n = 182）或纸质问卷（n = 211）获得的相同问题的相应水平相等。SMS、网络和纸质问卷组的回复率相似。
