这项研究使用线性结构关系建模技术(LISREL)来检查来自社区人口的1192人的纵向数据。其目标是在最初的评估中测试先验模型预测70-79岁老年人在2.0至2.5年内认知变化的能力。该模型包括22个人口统计变量、生理变量和心理社会变量，作为认知功能和认知变化的预测因子。这项研究使用了探索性-验证性设计，能够对验证性样本中探索性集合中开发的模型进行交叉验证。结构方程模型分析确定了4个内生模型变量(教育程度、剧烈活动、最大肺呼气流速和自我效能)作为研究期间认知变化的直接预测因素。
This study used a linear structural relations modeling technique( LISREL) to examine longitudinal data for 1,192 persons from a community-based population. The goal was to test the ability of an a priori model to predict cognitive change over a 2.0- to 2.5-year period in older adults aged 70-79 at the initial evaluation. The model included 22 demographic, physical, and psychosocial variables as predictors of cognitive function and cognitive change. The study used an exploratory-confirmatory design, enabling cross-validation of the model developed in the exploratory set in the confirmatory sample. Structural equation modeling analyses identified 4 endogenous model variables( education, strenuous activity, peak pulmonary expiratory flow rate, and self-efficacy) as direct predictors of cognitive change over the study period.
