The present study aims to examine how subjective age of older Korean Americans would be affected by functional disability and attitudes toward aging. We hypothesized that (a) both functional disability and attitudes toward aging would have a direct effect on subjective age and (b) the effect of functional disability on subjective age would be mediated by attitudes toward aging. Our analyses of the survey data with 208 community-dwelling Korean Americans aged 60 and older (mean age = 69.6, SD = 7.51) showed that the indirect effect of functional disability on subjective age through attitudes toward aging [–.020 (.009)] was significant (bias-corrected 95% confidence interval [–.039, –.006]). The findings suggest that functional disability fosters negative attitudes toward aging, which in turn leads to the feelings of being older than actual age. Our study suggests ways to preserve and promote positive perceptions of age and aging.

老年韩裔美国人的主观年龄：衰老态度介导的功能障碍的影响。

本研究旨在研究老年韩裔美国人的主观年龄如何受到功能障碍和对衰老的态度的影响。我们假设（a）功能障碍和对衰老的态度都会对主观年龄产生直接影响，（b）功能障碍对主观年龄的影响将通过对衰老的态度来调节。我们对 208 名 60 岁及以上居住在社区的韩裔美国人（平均年龄 = 69.6，SD = 7.51）的调查数据进行的分析表明，功能障碍通过对衰老的态度对主观年龄产生间接影响 [–.020 (.009) ] 是显着的（偏差校正的 95% 置信区间 [–.039, –.006]）。研究结果表明，功能障碍会培养对衰老的消极态度，这反过来又会导致感觉比实际年龄大。
