Using rhythm theory as a heuristic device, the goals of this study are to improve measurement strategy for wandering and to evaluate effects of various pacers (level of cognitive impairment, agitation, light) upon it. Large-scale integrated activity (LSI) monitor readings are evaluated as a proxy for visual observation in estimating daily wandering. Wandering rhythm (cycle frequency, duration) and pattern (lapping, pacing, random) are compared for various levels of cognitive impairment and agitation. Finally, twilight and red light are evaluated for effects on wandering at various levels of cognitive impairment and agitation. In stage 1, a comparative descriptive design is used to obtain LSI monitor readings and to time and code wandering rhythm over a twenty-four hour period and two subsequent two hour periods for twenty-four subjects in two residential care units. Subjects are categorized by level of cognitive impairment using the Folstein Mini-Mental State Exam and the Mattis Dementia Rating Scale and rated as agitated or nonagitated using the Cohen- Mansfield Agitation Inventory. T-tests, ANOVAs, proposed to evaluate stability of LSI monitor readings and wandering rhythm variables between two hour epochs on subsequent days, the extent to which a two hour epoch represents and entire twenty four hour period, and the extent to which LSI meter readings can substitute for visually observed rhythm. Visual inspection of plots, ANOVA, regression, and contingency analyses are planned to evaluate associations of cognitive impairment and agitation to wandering rhythm and pattern. In stage 2, a multiple case study design with an embedded interrupted time series experiment using nonequivalent dependent variables is proposed to evaluate the effects of light on wandering rhythm and pattern. Controlling for level of cognitive impairment and agitation, twelve cases are studied over twenty-one two hour periods: three baseline (average ambient daylight) periods followed by three replications of three experimental periods (twilight, bright red light, and dim red light) and three no treatment periods. Visual inspection, autoregression, and t and F tests are used to evaluate the impact of various light levels upon wandering rhythm and pattern. Though wandering poses a real problem in the care of cognitively- impaired persons, weak measurement and conceptual confusion have limited studies of it. From the perspective of rhythm theory, this study aims to reduce these methodological gaps and to evaluate light as one possible intervention for wandering behavior.

使用节奏理论作为启发式手段，本研究的目的是 改进游荡测量策略并评估治疗效果 不同的步行者(认知障碍程度，激动，光线)。 大规模综合活动(LSI)监测读数被评估为 视觉观察在估计日常漫游中的替代作用。流浪 节奏(周期频率、持续时间)和模式(圈速、起搏、随机) 比较了不同程度的认知障碍和焦虑症。 最后，评估黄昏和红光对漫步的影响。 不同程度的认知障碍和躁动。 在阶段1中，使用比较描述性设计来获得LSI 监测读数，并以时间和代码在24小时内游荡节奏 24名受试者分两次上两个小时的课时 住在两个养老院里。科目按以下级别进行分类 使用Folstein Mini-Mini-Mind State测验的认知障碍和 马蒂斯痴呆评定量表，并被评为焦虑症或非焦虑症 科恩-曼斯菲尔德激动量表。T检验，方差分析，建议 评估LSI监护仪读数和漂移节律变量的稳定性 在随后几天的两小时纪元之间，两个小时的范围 小时纪元表示整个二十四小时周期，并且范围 LSI仪表读数可以替代视觉观察到的节律。 对曲线图、方差分析、回归分析和偶然性分析进行目视检查 计划评估认知障碍和 激荡着游荡的节奏和模式。 在第二阶段，一个多案例研究设计，其中嵌入一个中断 使用非等价因变量的时间序列实验是 建议评估光对漫游节律和 图案。控制认知障碍和焦虑症的程度， 对12个病例进行了为期21个小时的研究：3个基线 (平均环境日光)周期，之后是三次复制 三个实验阶段(黄昏、大红光和暗红色 光照)和三个不治疗周期。目视检查， 使用自回归、t检验和F检验来评估 在漫游的节奏和图案上有不同的光线级别。虽然在流浪 在照顾认知障碍者方面带来了真正的问题，弱者 测量和概念混淆限制了对它的研究。从… 从节奏理论的角度，本研究旨在减少这些 方法学上的差距，并评估光作为一种可能的干预措施 因为他的游荡行为。
