An adult child's provision of care to an unmarried elderly mother varies both within and between families. Within-family differences address the variation in different children's behavior within in a family. Between-family differences refer to the propensities that members of a family-the children of one mother-share and that differentiate them from other families. Previous research suggests five hypotheses affecting either within-family or between-family differences. Data from multiple waves of the Asset and Health Dynamics Among the Oldest Old (AHEAD) cohort of the Health and Retirement Study (HRS; 16,719 observations on 5,607 mother-child dyads in 1,925 families) are used to estimate a multilevel model with a binary outcome. Results indicate substantial differences between families. Mother's characteristics, family composition, and family history account for about half the between-family differences.
成年子女对未婚老年母亲的照料在家庭内部和家庭之间都存在差异。家庭内部差异指的是一个家庭中不同子女行为的变化。家庭之间的差异指的是一个家庭的成员（一位母亲的子女）所共有的、并使他们与其他家庭区分开来的倾向。先前的研究提出了五个影响家庭内部或家庭之间差异的假设。健康与退休研究（HRS）中最年长者资产与健康动态（AHEAD）队列的多轮数据（对1925个家庭中5607对母子二元组的16719次观察）被用于估计一个具有二元结果的多层次模型。结果表明家庭之间存在显著差异。母亲的特征、家庭构成和家族史约占家庭之间差异的一半。
