Measuring physical activity (PA) in people with mild cognitive impairment or dementia can be difficult. The aim was to investigate the validity and acceptability of three different PA measurement methods. The mixed-method analysis included 49 participants with mild cognitive impairment or dementia, who completed a daily calendar recording PA, the International Physical Activity Questionnaire, and the Longitudinal Aging Study Amsterdam PA Questionnaire, and those who wore a Misfit Shine accelerometer. The quantitative analysis showed equal completion rates for the International Physical Activity Questionnaire and the accelerometer but a lower completion rate for the calendar. Correlations between outcome measures were moderate or strong. The qualitative analysis indicated that all measures were acceptable, though some participants required help to complete the calendars or fasten the accelerometers. The study supported the validity of these methods for people with mild cognitive impairment and mild dementia. Using accelerometers and completing calendars might increase the motivation to be active for some people.
测量轻度认知障碍或痴呆患者的身体活动（PA）可能较为困难。本研究旨在调查三种不同 PA 测量方法的有效性和可接受性。该混合方法分析纳入了 49 名轻度认知障碍或痴呆患者，他们完成了日常活动记录、国际体力活动问卷和阿姆斯特丹纵向老龄化研究体力活动问卷，以及佩戴了 Misfit Shine 加速度计。定量分析显示，国际体力活动问卷和加速度计的完成率相当，但日历的完成率较低。结果测量之间的相关性为中等或较强。定性分析表明，所有方法均具有可接受性，尽管一些参与者在填写日历或佩戴加速度计时需要帮助。该研究支持这些方法在轻度认知障碍和轻度痴呆患者中的有效性。使用加速度计和填写日历可能会提高一些人的活动积极性。
