尽管人们对识别认知变化的潜在相关性抱有很大兴趣，但过去的研究结果并不一致。本研究纳入了许多方法学特征，旨在最大限度地提高检测具有不同认知变化量的个体特征的灵敏度。采用二阶潜在增长曲线模型分析五种认知能力的认知变化，该模型适用于 18 至 99 岁健康成年人的中等大样本数据（一次 N 为 4,802，两次为 2,265，三次为 1,128）。即使对 18 岁至 39 岁、40 岁至 64 岁以及 65 岁以上的个体进行单独分析，几种认知能力的纵向变化也存在显着的个体差异。变化的潜在相关因素包括自我评价健康、视力、情绪、性格和生活方式的衡量标准。大多数变化的潜在相关因素都具有很高的可靠性，并且一些分析是基于由多种措施共同的方差确定的更可靠的因素。尽管有利于检测变化相关性的条件，但几乎没有证据表明认知变化受到任何所检查的变量的调节。讨论了认知变化相关性结果不一致的可能原因。
Although there has been considerable interest in identifying potential correlates of cognitive change, results of past studies have been inconsistent. The present study incorporated a number of methodological features intended to maximize sensitivity to detect characteristics of individuals with different amounts of cognitive change. Cognitive change in five cognitive abilities was analyzed with second-order latent growth curve models applied to data from a moderately large sample of healthy adults ranging from 18 to 99 years of age (N’s of 4,802 with one occasion, 2,265 with two occasions, and 1,128 with three occasions). There was significant individual difference variance in the longitudinal changes in several cognitive abilities, even in separate analyses of individuals between 18 and 39, 40 and 64, and over 65 years of age. Potential correlates of change included measures of self-rated health, vision, mood, personality, and lifestyle. Most of the potential correlates of change had high reliability, and several analyses were based on even more reliable factors determined by the variance common to multiple measures. Despite favorable conditions for detecting correlates of change, there was little evidence that cognitive change was moderated by any of the variables examined. Possible reasons for the inconsistent results regarding correlates of cognitive change are discussed.
