关于成功老龄化的研究通常将测试分数分布中处于上端的老年人定义为成功的老年人。对成功衰老的另一种定义要求老年人的健康水平达到或高于年轻人的平均水平，并长期保持这一水平。在这里，我们以1463名年龄在50岁到85岁之间的人为样本，检验了成功衰老的定义。基于认知和非认知变量的主坐标分析，我们确定了55名（8.3%）70-85岁的高功能老年人。这组老年人在一系列认知任务中表现出更高的表现。这一群体的非认知因素包括教育和主观健康。5年后，参与者再次接受了测试，并重复了相同类型的分析。在剩下的最初被归类为高功能的人中，有18人（35%）仍然保持着高功能，因此符合成功衰老的定义。受教育年限是判断一个人能否长期保持成功的重要指标。
Studies of successful aging have typically defined elderly who fall in the upper end of a distribution of test scores as successful. A different definition of successful aging requires that older adults fall at or above the mean level of younger adults and maintain this level over time. Here we examined this definition of successful aging in a sample of 1463 individuals between the ages of 50 of 85. Based on principal coordinate analysis of cognitive and non-cognitive variables, we identified a group of 55 (8.3%) 70-85 years olds that were high functioning. This group of elderly showed elevated performance on a range of cognitive tasks. Non-cognitive factors that characterized this group included education and subjective health. The participants were retested 5 years later and the same type of analysis was repeated. Of the remaining individuals who initially were classified as high functioning, 18 (35%) remained high functioning and thus met the definition for successful aging. Years of education was a significant predictor of who remained successful over time.
