The relationships of fear of falling and fall-related efficacy with measures of basic and instrumental activities of daily living (ADL-IADL) and physical and social functioning were evaluated in a cohort of community-living elderly persons.
Sociodemographic, medical, psychological, and physical performance (e.g., gait speed, timed hand function) measures were administered, during an in-home assessment, to a probability sample of 1,103 residents of New Haven, Connecticut, who were > or = 72 years of age. Falls and injuries in the past year, fear of falling, and responses to the Falls Efficacy Scale were also ascertained. The three dependent variables included a 10-item ADL-IADL scale, an 8-item social activity scale, and a scale of relative physical activity level.
Among cohort members, 57% denied fear of falling whereas 24% acknowledged fear but denied effect on activity; 19% acknowledged avoiding activities because of fear of falling. Twenty-four percent of recent fallers vs 15% of nonfallers acknowledged this activity restriction (chi 2 = 13.1; p < .001). Mean fall-related efficacy score among the cohort was 84.9 (SD 20.5), 79.8 (SD 23.4), and 88.1 (SD 17.9) among fallers and nonfallers, respectively (p < or = .0001). Fall-related efficacy proved a potent independent correlate of ADL-IADL (partial correlation = .265, p < .001); physical (partial correlation = .234, p < .001); and social (partial correlation = .088, p < .01), functioning in multiple regression models after adjusting for sociodemographic, medical, psychological, and physical performance covariates as well as history of recent falls and injuries. Fear of falling was only marginally related (p = .05) with ADL-IADL functioning and was not associated with higher level physical or social functioning.
The strong independent association between self-efficacy and function found in this study suggests that clinical programs in areas such as prevention, geriatric evaluation and management, and rehabilitation should attempt simultaneously to improve physical skills and confidence. Available knowledge of the factors influencing efficacy should guide the development of these efficacy-building programs.
在一组社区居住的老年人中,评估了跌倒恐惧和与跌倒相关的效能感与基本和工具性日常生活活动(ADL - IADL)测量指标以及身体和社会功能之间的关系。
在家庭评估期间,对康涅狄格州纽黑文市1103名年龄≥72岁的居民进行概率抽样,收集社会人口统计学、医学、心理和身体表现(如步态速度、定时手部功能)等测量数据。还确定了过去一年中的跌倒和受伤情况、跌倒恐惧以及对跌倒效能量表的反应。三个因变量包括一个10项的ADL - IADL量表、一个8项的社会活动量表以及一个相对身体活动水平量表。
在队列成员中,57%否认有跌倒恐惧,24%承认有恐惧但否认对活动有影响;19%承认因害怕跌倒而避免活动。近期跌倒者中有24%承认有这种活动限制,而非跌倒者中这一比例为15%(χ² = 13.1;p <.001)。队列中跌倒相关效能感的平均得分分别为84.9(标准差20.5),跌倒者和非跌倒者分别为79.8(标准差23.4)和88.1(标准差17.9)(p ≤.0001)。在调整了社会人口统计学、医学、心理和身体表现协变量以及近期跌倒和受伤史后,跌倒相关效能感在多元回归模型中被证明是ADL - IADL(偏相关系数 =.265,p <.001)、身体功能(偏相关系数 =.234,p <.001)和社会功能(偏相关系数 =.088,p <.01)的有力独立相关因素。跌倒恐惧仅与ADL - IADL功能有微弱关联(p =.05),且与更高水平的身体或社会功能无关。
本研究发现自我效能感与功能之间存在强烈的独立关联,这表明在预防、老年评估与管理以及康复等领域的临床项目应同时尝试提高身体技能和信心。影响效能感的因素的现有知识应指导这些效能建设项目的开展。
