目的：孤独感与一般老年人口的认知功能有关。先前的研究进一步表明，孤独感与抑郁症状有很强的相关性，这两种结构可以相互加强，从而降低幸福感。然而，这种关系尚未在美国华裔老年人中进行过研究。本研究试图弥合这一知识差距。方法：数据来自一项针对大芝加哥地区 3,159 名美国华裔老年人的人口研究。进行逐步多元回归分析来检查孤独感、抑郁症状和整体认知功能之间的关系。结果：孤独感与美国华裔老年人的整体认知功能较差有关，尽管在调整抑郁症状后这种关系变得不显着。孤独感和认知功能之间的交互项具有统计显着性 (p < .01)。研究结果进一步强调了年龄、教育程度、子女数量、家庭人数以及在美国居住时间长短对美国华裔老年人认知功能的重要性。讨论：研究结果表明，孤独感和抑郁症状共同影响美国华人老年人的认知功能。讨论了研究结果的研究和临床意义。
Objective: Loneliness has been associated with cognitive functioning in the general older adult population. Previous studies further indicate that loneliness has a strong association with depressive symptoms and the two constructs can reinforce each other to diminish well-being. However, such relationships have not been examined in U.S. Chinese older adults. This study attempts to bridge this knowledge gap. Method: Data were drawn from a population-based study of 3,159 U.S. Chinese older adults in the Greater Chicago area. Stepwise multivariate regression analyses were conducted to examine the relationship between loneliness, depressive symptoms, and global cognitive functioning. Results: Loneliness was associated with poor global cognitive functioning in U.S. Chinese older adults, though the relationship became nonsignificant after adjustment for depressive symptoms. The interaction term between loneliness and cognitive functioning was statistically significant (p < .01). The findings further highlight the importance of age, education, number of children, number of people in household, and length of residence in the U.S. in cognitive functioning among U.S. Chinese older adults. Discussion: The study findings indicate that loneliness and depressive symptoms act together to influence cognitive functioning in U.S. Chinese older adults. Research and clinical implications of the findings are discussed.
