This study investigated mean-level changes and intraindividual variability of self-esteem among maltreated (n=142) and nonmaltreated (n=109) school-aged children from low-income families. Longitudinal factor analysis revealed higher temporal stability of self-esteem among maltreated children compared to nonmaltreated children. Cross-domain latent growth curve models indicated that nonmaltreated children showed higher initial levels and greater increases in self-esteem than maltreated children, and that the initial levels of self-esteem were significantly associated with depressive symptoms among maltreated and nonmaltreated children. The average level (mean of repeated measurements) of self-esteem was predictive of depression at the final occasion for both maltreated and nonmaltreated children. For nonmaltreated children intraindividual variability of self-esteem had a direct contribution to prediction of depression. The findings enhance our understanding of developmental changes in self-esteem and the role of the average level and within-person variability of self-esteem in predicting depressive symptoms among high-risk children.
本研究调查了来自低收入家庭的受虐待学龄儿童（n = 142）和未受虐待学龄儿童（n = 109）自尊的平均水平变化和个体内变异性。纵向因素分析显示，与未受虐待儿童相比，受虐待儿童的自尊具有更高的时间稳定性。跨领域潜在增长曲线模型表明，未受虐待儿童的自尊初始水平更高，且增长幅度大于受虐待儿童，并且自尊的初始水平与受虐待和未受虐待儿童的抑郁症状显著相关。对于受虐待和未受虐待儿童，自尊的平均水平（重复测量的均值）在最后阶段可预测抑郁。对于未受虐待儿童，自尊的个体内变异性对抑郁预测有直接贡献。这些发现增进了我们对自尊发展变化以及自尊平均水平和个体内变异性在预测高危儿童抑郁症状中所起作用的理解。
