This study examined the longitudinal association between marital instability and child sleep problems at ages 9 and 18 months in 357 families with a genetically unrelated infant adopted at birth. This design eliminates shared genes as an explanation for similarities between parent and child. Structural equation modeling indicated that T1 marital instability predicted T2 child sleep problems, but T1 child sleep problems did not predict T2 marital instability. This result was replicated when models were estimated separately for mothers and fathers. Thus, even after controlling for stability in sleep problems and marital instability and eliminating shared genetic influences on associations using a longitudinal adoption design, marital instability prospectively predicts early childhood sleep patterns.
这项研究考察了 357 个家庭中，在婴儿出生时被领养的、基因上没有亲缘关系的婴儿，其婚姻不稳定与 9 个月和 18 个月时的儿童睡眠问题之间的纵向关联。这种设计消除了作为父母与孩子之间相似性的共同基因解释。结构方程模型表明，T1 婚姻不稳定预测 T2 儿童睡眠问题，但 T1 儿童睡眠问题不能预测 T2 婚姻不稳定。当分别为母亲和父亲估计模型时，得到了相同的结果。因此，即使在控制睡眠问题和婚姻不稳定的稳定性以及使用纵向收养设计消除关联的共同遗传影响之后，婚姻不稳定仍能前瞻性地预测儿童早期的睡眠模式。
