This study modeled the causal relationship between physical health and depression among a sample of 315 people providing home care for a spouse who had been diagnosed as having Alzheimer's disease. In addition to significant stability paths and correlations among variables at any one point in time, significant lagged paths were found in which depression (1) predicted physical health (2), depression (2) predicted physical health (3), and depression (1) predicted burden (2). Contrasting the overall model for husband and wife caregivers over a 6-month period indicated that the model was significant for wives but not for husbands.
本研究对315名在家照顾已被诊断患有阿尔茨海默病配偶的人员样本中身体健康与抑郁之间的因果关系进行了建模。除了在任何一个时间点变量之间存在显著的稳定性路径和相关性外，还发现了显著的滞后路径，即抑郁（1）预测身体健康（2），抑郁（2）预测身体健康（3），以及抑郁（1）预测负担（2）。对丈夫和妻子照顾者在6个月期间的整体模型进行对比表明，该模型对妻子有显著意义，但对丈夫没有。
