How and when concerns about falls emerge is not yet completely known, because these concerns are present in both people with and without a falls history. The aim of this study was to investigate the role of catastrophic beliefs about falls and previous falls in the development of concerns about falls and resulting mobility restrictions (MR).
Within a cross-sectional design, 896 older people (mean age 76.2 +/- 4.7) living independently in the community completed a battery of questionnaires. Self-report data was gathered on previous falls, catastrophic beliefs about consequences of a fall (Catastrophizing About Falls Scale), concerns about falls (modified Falls Efficacy Scale) and mobility restrictions during daily life (Sickness Impact Profile 68).
Using structural equation modelling, we found that the number of falls in the previous year was not directly related to mobility restrictions in daily life, but via an increase of concerns about falls. Also catastrophic beliefs about the consequences of falls were related to concerns about falls and to mobility restrictions. Goodness-of-fit indices revealed that the presented model had an acceptable fit. Alternative models resulted in lesser-fit indices.
Both previous falls and catastrophic beliefs about falls are unique and independent predictors of concerns about falls and, subsequently, of mobility restrictions. A cognitive-behavioural perspective upon mobility restrictions may provide important additional components for treatment and prevention of excessive concerns about falls in older people.
跌倒担忧如何以及何时出现尚未完全明确,因为有跌倒史和无跌倒史的人群中均存在此类担忧。本研究旨在调查对跌倒的灾难性信念及既往跌倒在跌倒担忧及由此导致的活动受限(MR)发展过程中的作用。
在横断面设计中,896名独立居住在社区的老年人(平均年龄76.2±4.7岁)完成了一系列问卷调查。收集了关于既往跌倒、对跌倒后果的灾难性信念(跌倒灾难化量表)、跌倒担忧(改良跌倒效能感量表)以及日常生活中活动受限(疾病影响概况68项)的自我报告数据。
使用结构方程模型,我们发现前一年的跌倒次数与日常生活中的活动受限并无直接关联,而是通过增加跌倒担忧来产生影响。此外,对跌倒后果的灾难性信念与跌倒担忧及活动受限相关。拟合优度指数显示所提出的模型具有可接受的拟合度。替代模型的拟合度指数较低。
既往跌倒和对跌倒的灾难性信念都是跌倒担忧以及随后活动受限的独特且独立的预测因素。从认知行为角度看待活动受限可能为治疗和预防老年人对跌倒的过度担忧提供重要的额外要素。
