BACKGROUND/STUDY CONTEXT: Everyday cognition represents the ability to solve problems within domains that are representative of issues faced by adults on a daily basis. The current study examined individual differences in everyday cognitive ability among aging Black/African American adults.
Demographic data on age, gender, education, physical functioning, chronic illnesses, self-reported health, and depression were collected from 248 African American adults (mean age = 67.8 years, standard deviation = 8.47 years). A multiple indicators, multiple causes (MIMIC) modeling approach was used to examine the associations of individual characteristics with latent everyday cognitive ability and composite score indicators.
Age, depressive symptoms, and number of chronic illnesses were negatively related to latent everyday cognition. The individual characteristics of age, depressive symptoms, self-rated health, and education were directly associated with composite indicators of latent everyday cognition. This suggests that within this sample of older Black/African American adults that certain composite scores (i.e., telephone use, food preparation, and finances) may be particularly sensitive to these individual characteristics.
These results identify specific sources of variability in everyday cognitive ability among aging Blacks/African Americans. These individual differences should be accounted for when studying everyday cognition among Blacks/African Americans and when comparing the everyday cognitive ability of Blacks/African Americans with other groups.
背景/研究背景:日常认知代表了在成人日常面临的问题所代表的领域内解决问题的能力。当前研究考察了老年黑人/非裔美国成年人日常认知能力的个体差异。
收集了248名非裔美国成年人(平均年龄 = 67.8岁,标准差 = 8.47岁)的年龄、性别、教育程度、身体功能、慢性病、自我报告的健康状况和抑郁等人口统计学数据。采用多指标、多原因(MIMIC)建模方法来检验个体特征与潜在日常认知能力及综合得分指标之间的关联。
年龄、抑郁症状和慢性病数量与潜在日常认知呈负相关。年龄、抑郁症状、自我健康评分和教育程度等个体特征与潜在日常认知的综合指标直接相关。这表明在这个老年黑人/非裔美国成年人样本中,某些综合得分(即电话使用、食物准备和财务)可能对这些个体特征特别敏感。
这些结果确定了老年黑人/非裔美国成年人日常认知能力差异的具体来源。在研究黑人/非裔美国成年人的日常认知以及将黑人/非裔美国成年人的日常认知能力与其他群体进行比较时,应考虑这些个体差异。
