To evaluate the feasibility and validity of actigraphy as a measurement of agitation in dementia.
Participants aged 65 and older, diagnosed with dementia, residing in a geriatric psychiatry inpatient unit or long-term care facility were included in a cross-sectional study. Agitation was assessed using the Cohen-Mansfield Agitation Inventory (CMAI) and the Neuropsychiatric Inventory (NPI). Actigraphy was measured over seven days and compared across groups categorized as low or high agitation based on a CMAI cutoff score of 50.
Twenty participants were enrolled (mean age = 74.3 years, standard deviation [SD] = 8.69). The 24-hour mean motor activity as measured with actigraphy was significantly different between the low and high agitation groups (180.23, SD = 86.34 versus 81.51, SD = 30.29, Z = 2.29; p = 0.02). Most actigraph variables had significant correlations with CMAI and NPI scores.
Actigraphy was highly correlated with informant-based methods for measuring agitation in individuals with dementia and actigraphy may be useful tool for measuring agitation.
评估活动记录仪在痴呆患者激越评估中的可行性和有效性。
本横断面研究纳入了年龄在 65 岁及以上、被诊断为痴呆、居住在老年精神病住院病房或长期护理机构的患者。激越通过 Cohen-Mansfield 激越量表（CMAI）和神经精神问卷（NPI）进行评估。活动记录仪的测量时间为 7 天，并根据 CMAI 截断值为 50 分将患者分为低激越组或高激越组，对两组进行比较。
共纳入 20 名参与者（平均年龄 74.3 岁，标准差 [SD] = 8.69）。使用活动记录仪测量的 24 小时平均运动量在低激越组和高激越组之间有显著差异（180.23，SD = 86.34 与 81.51，SD = 30.29，Z = 2.29；p = 0.02）。大多数活动记录仪变量与 CMAI 和 NPI 评分具有显著相关性。
活动记录仪与基于知情者的方法高度相关，可用于评估痴呆患者的激越，可能是一种评估激越的有用工具。
