目标开发原始阿拉巴马大学伯明翰分校老龄生活空间评估研究 (LSA-D) 的德语版本，用于测量过去 4 周内老年人的社区流动性，并评估其对城市和农村人口的结构有效性的老年人。设计横断面验证研究。设置德国城市和农村门诊医院设置的两个研究中心。参与者总共招募了 N=83 名居住在社区的老年人（n=40 来自城市，n=43 来自农村地区；平均年龄为 78.5 岁（SD=5.4）；49.4% 男性）。主要和次要结果测量翻译的 LSA-D 的最终版本与作为主要结果测量（主要假设）的日常生活活动和工具性活动 (ADL/iADL) 的限制有关；加上社会人口因素，功能流动性、自评健康、平衡信心和跌倒史作为获得结构效度的次要结果指标。对健康的进一步描述性测量包括握力、认知功能筛查、合并症和交通工具的使用。为了评估结构有效性，使用双变量回归和多元调整回归模型检查总样本和城市和农村子样本的 LSA-D 与主要和次要结果测量之间的相关性。LSA-D 的描述性分析包括每个区域的不同评分方法。使用非参数引导程序估计所有参数。结果在总样本的多重调整模型中，ADL/iADL 限制的数量（β=-0.26；95% CI=-0.42 至 -0.08），定时启动测试（β=-0.37；95% CI=-） 0.68 到 -0。14）、共同生活安排（β=0.22；95% CI=0.01 至 0.44）和过去 6 个月跌倒史（β=-0.22；95% CI=-0.41 至 -0.05）显示与 LSA 显着相关-D 综合评分，而居住在城市地区（β=-0.19；95% CI=-0.42 至 0.03）和男性（β=0.15；95% CI=-0.04 至 0.35）不显着。结论 LSA-D 是衡量德国社区老年人过去 4 周内在流动的城市和农村环境中生活空间流动性的有效工具。试用注册号 DRKS00019023。可应合理要求提供数据。数据将在合理、方法上合理的请求下尽快提供，以实现已批准提案的目标。可用数据包括个人参与者数据，这些数据是本文报告的结果去识别化后的基础，数据字典和解析代码。数据将在文章发表后至少 3 个月内提供，并在文章发表后 5 年结束。提案应发送至 sandra.muemken@charite.de 或 joern.kiselev@charite.de。

Validation of the German Life-Space Assessment (LSA-D): cross-sectional validation study in urban and rural community-dwelling older adults

Objectives To develop a German version of the original University of Alabama at Birmingham Study of Aging Life-Space Assessment (LSA-D) for measurement of community mobility in older adults within the past 4 weeks and to evaluate its construct validity for urban and rural populations of older adults. Design Cross-sectional validation study. Setting Two study centres in urban and rural German outpatient hospital settings. Participants In total, N=83 community-dwelling older adults were recruited (n=40 from urban and n=43 from rural areas; mean age was 78.5 years (SD=5.4); 49.4% men). Primary and secondary outcome measures The final version of the translated LSA-D was related to limitations in activities and instrumental activities of daily living (ADL/iADL) as primary outcome measure (primary hypothesis); and with sociodemographic factors, functional mobility, self-rated health, balance confidence and history of falls as secondary outcome measures to obtain construct validity. Further descriptive measurements of health included hand grip strength, screening of cognitive function, comorbidities and use of transportation. To assess construct validity, correlations between LSA-D and the primary and secondary outcome measures were examined for the total sample, and urban and rural subsamples using bivariate regression and multiple adjusted regression models. Descriptive analyses of LSA-D included different scoring methods for each region. All parameters were estimated using non-parametric bootstrapping procedure. Results In the multiple adjusted model for the total sample, number of ADL/iADL limitations (β=−0.26; 95% CI=−0.42 to −0.08), Timed Up and Go Test (β=−0.37; 95% CI=−0.68 to −0.14), shared living arrangements (β=0.22; 95% CI=0.01 to 0.44) and history of falls in the past 6 months (β=−0.22; 95% CI=−0.41 to −0.05) showed significant associations with the LSA-D composite score, while living in urban area (β=−0.19; 95% CI=−0.42 to 0.03) and male gender (β=0.15; 95% CI=−0.04 to 0.35) were not significant. Conclusion The LSA-D is a valid tool for measuring life-space mobility in German community-dwelling older adults within the past 4 weeks in ambulant urban and rural settings. Trial registration number DRKS00019023. Data are available upon reasonable request. Data will be made available on reasonable, methodologically sound request as soon as possible to achieve the aims of the approved proposal. Available data include individual participant data that underlie the results reported in this article after its deidentification, data dictionary and the analytical code. Data will be available at least 3 months after, and ending 5 years following article publication. Proposals should be directed at sandra.muemken@charite.de or joern.kiselev@charite.de.
