在第一次杜克老龄化纵向研究的完整数据集中，研究了认知和智力功能的16项指标（11项韦氏成人智力量表子测验，3项韦氏记忆测验子测验，2项反应时间指标）的时间变化。这16项措施的变化模式是通过"隶属度"分析确定的-这是一种确定时间变化模式的一般模式，不需要对变化轨迹进行参数假设，也不需要对抽样人口的同质性进行假设。分析表明，16项测量的时间变化可以用五种潜在模式来描述，这些模式反映了极端晚年智力功能的复杂模式。研究了这五种智力模式与年龄的关系，以及与心理和身体健康指标的关系。这些结果强调，需要在以后的生活中，以多维形式描述变化的健康和功能的综合模型。
Temporal changes in 16 measures of cognitive and intellectual functioning (11 wechsler adult intelligence scale subtests, 3 wechsler memory test subscales, 2 measures of reaction time) were studied in the full data set from the first duke longitudinal study of aging. Patterns of change in these 16 measures were identified through a ‘grade-of-membership’ analysis — a general model for identifying patterns in temporal variation that does not require parametric assumptions about the trajectory of change or assumptions about the homogeneity of the sampled population. The analyses showed that the temporal variation of the 16 measures could be described by five latent patterns that reflected the complex patterning of intellectual functioning in extreme late life. The relation of these five patterns of intellectual ability to age was examined, as were the relationships to measures of mental and physical health. These results underline the needs for comprehensive models of health and functioning in later life that describe changes in a multidimensional form.
