To develop and validate a wandering typology.
Cross-sectional, correlational descriptive design.
Twenty-two nursing homes and six assisted living facilities.
One hundred forty-two residents with dementia who spoke English, met Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition, criteria for dementia, scored less than 24 on the Mini-Mental State Examination (MMSE), were ambulatory (with or without assistive device), and maintained a stable regime of psychotropic medications were studied.
Data on wandering were collected using direct observations, plotted serially according to rate and duration to yield 21 parameters, and reduced through factor analysis to four components: high rate, high duration, low to moderate rate and duration, and time of day. Other measures included the MMSE, Minimum Data Set 2.0 mobility items, Cumulative Illness Rating Scale-Geriatric, and tympanic body temperature readings.
Three groups of wanderers were identified through cluster analysis: classic, moderate, and subclinical. MMSE, mobility, and cardiac and upper and lower gastrointestinal problems differed between groups of wanderers and in comparison with nonwanderers.
Results have implications for improving identification of wanderers and treatment of possible contributing factors.
制定并验证漫游类型学。
横断、相关描述性设计。
22 家养老院和 6 家辅助生活设施。
142 名患有痴呆症且能讲英语的居民，符合《精神障碍诊断与统计手册》第 4 版痴呆标准，简易精神状态检查（MMSE）得分<24，能走动（有或无辅助设备），精神药物治疗稳定。
使用直接观察法收集漫游数据，根据频率和持续时间连续绘制，得出 21 个参数，并通过因子分析减少到四个成分：高频率、高持续时间、低至中等频率和持续时间、以及时间。其他措施包括 MMSE、最低数据集 2.0 移动项目、累积疾病评分量表-老年、和鼓膜体温读数。
通过聚类分析确定了三组漫游者：经典型、中度型和亚临床型。MMSE、活动能力以及心脏和上、下胃肠道问题在漫游者组之间以及与非漫游者组之间存在差异。
研究结果对改善漫游者的识别和治疗可能的促成因素具有重要意义。
