Aim of this study was to test the reliability and validity of the life-space measures and walking speed delivered by the MOBITEC-GP app. Participants underwent several supervised walking speed assessments as well as a 1-week life-space assessment during two assessment sessions 9 days apart. Fifty-seven older adults (47.4% male, mean age= 75.3 (±5.9) years) were included in the study. The MOBITEC-GP app showed moderate to excellent test-retest reliability (ICCs between 0.584 and 0.920) and validity (ICCs between 0.468 and 0.950) of walking speed measurements of 50 meters and above and of most 1-week life-space parameters, including life-space area, time spent out-of-home, and action range. The MOBITEC-GP app for Android is a reliable and valid tool for the assessment of real-life walking speed (at distances of 50 metres and above) and life-space parameters of older adults. Future studies should look into technical issues more systematically in order to avoid invalid measurements.
本研究的目的是测试MOBITEC-GP应用程序提供的生活空间测量和步行速度的可靠性和有效性。参与者在相隔9天的两次评估中接受了多次有监督的步行速度评估以及为期1周的生活空间评估。57名老年人（男性占47.4%，平均年龄 = 75.3（±5.9）岁）被纳入研究。MOBITEC-GP应用程序在测量50米及以上步行速度和大多数为期1周的生活空间参数（包括生活空间面积、外出时间和活动范围）方面显示出中等到优秀的重测可靠性（组内相关系数在0.584至0.920之间）和有效性（组内相关系数在0.468至0.950之间）。适用于安卓系统的MOBITEC-GP应用程序是评估老年人实际步行速度（50米及以上距离）和生活空间参数的可靠且有效的工具。未来的研究应更系统地研究技术问题，以避免无效测量。
