目的:探讨日常生活能力在慢性病与老年人焦虑抑郁关系中的中介作用。方法:使用中国人民大学中国调查与数据中心的《北京市老年人焦虑测量数据》,有效样本量为1318人。评定焦虑、抑郁水平的量表分别为老年人焦虑量表(GAI)和简版老年抑郁量表(GDS-15),日常生活能力采取自编问卷测量。采用结构方程模型分析老年人慢性病、日常生活能力、焦虑抑郁三者之间的关系。结果:老年人焦虑检出率为6. 9%,抑郁检出率为24. 0%。模型中,慢性病对老年人焦虑抑郁具有统计学意义的正向预测作用(B=0. 31,P

Objective: To explore the mediating effects of the elderly＇s activities of daily living in the relationship among chronic disease，anxiety and depression. Methods: The data of " A survey of anxiety of the elderly in Beijing" were gathered by using the National Survey Ｒesearch Center at Ｒenmin University of China，with an effective sample size of 1318 elder people. The Geriatric Anxiety Inventory ( GAI) and the Short Form Geriatric Depression Scale ( GDS-15) were used to measure the elderly＇s anxiety and depression. The elderly＇s activities of daily living was measured by self-designed questionnaire. The structural equation model was applied to examine the relationship among chronic diseases，activities of daily living，anxiety and depression. Ｒesults: The anxiety detection rate was 6. 9% and the depression detection rate was 24. 0%. The model showed that the elderly＇ s chronic diseases had statistically positive predictive effects on anxiety and depression ( B = 0. 31，P ＜ 0. 001) . The mediating effect of activities of daily living between chronic diseases，anxiety and depression accounted for 14%. Conclusion: The anxiety and depression may be associated with chronic diseases in the elderly，and the activities of daily living partially mediates the effect of the relationship between the elderly＇ s chronic disease，anxiety and depression.
