The purpose of this study was to consider the feasibility, reliability, and validity of MotionWatch 8. A total of 249 residents were recruited from 26 assisted living settings. Data collection included demographics, comorbidities, function (Barthel Index), physical activity (MotionWatch 8), and falls. The mean age of participants was 86.86 (SD = 7.0), the majority were women 179 (74%) and White (N = 232, 96%). A total of 86% of participants wore the MotionWatch 8. There were no significant differences in physical activity over 3 days of testing. The MotionWatch 8 findings were significantly associated with activities of daily living (ADL) function. There were no significant differences in ADL function or physical activity between those who did and did not fall. The study provides additional support for the feasibility, reliability, and validity of the MotionWatch 8 and confirms that older adults living in assisted living settings spend the majority of their time in sedentary activity.
