This study examined the impact of family conflict on internalizing and externalizing behavior at age 8 for children born low birth weight (LBW) and preterm (PT), with specific attention to the moderating role of early temperament.
The sample included 728 families enrolled in the longitudinal study of the Infant Health and Development Program. The study relied on maternal reports of child temperament at age 1, family conflict at age 6(1/2) years and 8 years, and child behavior at age 8 years.
Children exposed to high levels of family conflict had more internalizing problems. Child temperament assessed in infancy moderated the impact of family conflict on externalizing but not internalizing problem behavior.
LBW/PT children with a difficult temperament are more at risk for poor developmental outcomes, such as externalizing behavior problems, when exposed to family conflict than children with a less difficult temperament.
本研究考察了家庭冲突对低出生体重（LBW）和早产（PT）儿童8岁时内化行为和外化行为的影响，并特别关注早期气质的调节作用。
样本包括728个参与婴儿健康与发展项目纵向研究的家庭。该研究依赖于母亲对孩子1岁时的气质、6.5岁和8岁时的家庭冲突以及8岁时孩子行为的报告。
经历高水平家庭冲突的儿童有更多的内化问题。婴儿期评估的儿童气质调节了家庭冲突对外化问题行为的影响，但对内化问题行为没有调节作用。
与气质不那么难养的儿童相比，气质难养的低出生体重/早产儿童在面临家庭冲突时，出现诸如外化行为问题等不良发育结果的风险更高。
