Cognitive functioning is a central component of successful aging. Yet, there are few published instruments for brief and reliable self-administered cognitive assessment that could be used in large population-based studies of community-dwelling elderly people.
We examined the utility of a self-administered cognitive screening instrument in a group of community-dwelling older adults, and we evaluated correlations of the performance on this measure with demographic variables and specific indicators of self-rated successful aging.
We assessed 182 well-educated adults ages 58 to 99 with a modified version of a previously published cognitive screening instrument (Cognitive Assessment Screening Test--Revised; CAST-R), a measure of cognitive complaints (Cognitive Failures Questionnaire; CFQ), and a self-rating of successful aging. We used the SF-36 Physical and Mental Composite Scores as measures of physical and mental health-related functioning.
As expected, most individuals performed well on the CAST-R; only 7% of participants fell below a previously established cut score for cognitive impairment. CAST-R scores were positively correlated with level of education, income, SF-36 Mental Composite Scores, and a self-rating of successful aging, and negatively correlated with chronological age. Scores on the CAST-R were not correlated with cognitive complaints (CFQ total score) or SF-36 Physical Composite Scores.
A self-administered cognitive screening tool may be a useful, albeit limited, way of screening for cognitive disabilities among well-educated, community-dwelling older adults. Although preliminary, significant associations with several successful aging-related variables in expected directions represent the first step in establishing the validity of the CAST-R.
认知功能是成功老龄化的核心组成部分。然而,几乎没有已发表的可用于大规模社区居住老年人基于人群研究的简短且可靠的自我管理认知评估工具。
我们在一组社区居住的老年人中检验了一种自我管理认知筛查工具的效用,并评估了该测量方法的表现与人口统计学变量以及自我评定成功老龄化的特定指标之间的相关性。
我们使用先前发表的认知筛查工具的修订版(认知评估筛查测试 - 修订版;CAST-R)、认知抱怨测量方法(认知失误问卷;CFQ)以及成功老龄化的自我评定,对182名年龄在58岁至99岁之间、受过良好教育的成年人进行了评估。我们使用SF-36身体和心理综合评分作为与身心健康相关功能的测量指标。
正如预期的那样,大多数个体在CAST-R上表现良好;只有7%的参与者低于先前确定的认知障碍临界分数。CAST-R分数与教育水平、收入、SF-36心理综合评分以及成功老龄化的自我评定呈正相关,与实际年龄呈负相关。CAST-R分数与认知抱怨(CFQ总分)或SF-36身体综合评分无关。
自我管理的认知筛查工具可能是一种有用的(尽管有限)方法,用于在受过良好教育的社区居住老年人中筛查认知障碍。尽管是初步的,但与几个与成功老龄化相关变量在预期方向上的显著关联代表了确立CAST-R有效性的第一步。
