To test the hypothesis that mobility, activities of daily living, and the interaction between them can play a key role in determining perceived physical environment barriers among community-dwelling elderly.
Cross-sectional.
Community.
One hundred and ninety-seven community-dwelling elderly with more than 7 points on the Short Portable Mental State Questionnaire and less than 7 points on the Geriatric Depression Scale (15 items).
None.
Time Get-up and Go test (TUG), the subscales of basic activity of daily living (BADL)/instrumental activities of daily living (IADL) of the Hierarchy of Care Required (HCR), and the physical/structural subscale of the Craig Hospital Inventory of Environmental Factors in Community-dwelling Elderly in Taiwan were used to measure mobility, activities of daily living and perceived physical environment barriers, respectively. Hierarchical linear regression analyses were used to test the study hypothesis.
Significant and positive relations were found to exist between perceived physical environment barriers and (1) the TUG time (β=.300, p<.05), and (2) the IADL score for the HCR (β=.322, p<.05), respectively. A significant and negative relation existed between perceived physical environment barriers and the interaction term (the TUG time and the IADL score for the HCR) (β=-.211, p<.05).
Mobility, IADL and the interaction between them are found to be significant determinants of perceived physical environment barriers in the community-dwelling elderly under consideration. Strategies targeting the enhancement of mobility among community-dwelling elderly are suggested to lead to improvements in the degree to which physical environment barriers are perceived. This beneficial effect could be greater in the case of elderly individuals with better IADL function.
验证以下假说，即移动能力、日常生活活动以及两者之间的相互作用在确定社区居住老年人对物理环境障碍的感知中起着关键作用。
横断面研究。
社区。
197 名社区居住的老年人，他们在简短精神状态问卷中得分超过 7 分，在老年抑郁量表（15 项）中得分低于 7 分。
无。
时间站起和行走测试（TUG）、照顾需求层次的日常生活活动的基本活动/工具性活动的分量表（BADL/IADL）和台湾社区居住老年人克雷格医院环境因素量表的物理/结构分量表，分别用于测量移动能力、日常生活活动和感知的物理环境障碍。使用分层线性回归分析来检验研究假设。
发现感知的物理环境障碍与（1）TUG 时间（β=.300，p<.05）和（2）HCR 的 IADL 得分（β=.322，p<.05）之间存在显著正相关关系。感知的物理环境障碍与 TUG 时间和 HCR 的 IADL 得分之间的交互项（β=-.211，p<.05）之间存在显著负相关关系。
移动能力、IADL 以及两者之间的相互作用被发现是考虑中的社区居住老年人感知物理环境障碍的重要决定因素。建议针对社区居住老年人提高移动能力的策略，以改善对物理环境障碍的感知程度。对于日常生活活动功能较好的老年人，这种有益效果可能更大。
