This study examined how maternal distress mediates the link between exposure to community violence (CV) and the development of early child behavior problems. Research was conducted among 160 children, 3,0 to 5,11 in age, who resided in high-crime neighborhoods. Using structural equation modeling, latent variables were constructed to identify model components: maternal socioeconomic status (SES) and public assistance status, exposure to CV (maternal perceptions of local violence, social disorder, and fear of crime; and frequency of child cowitnessing violent events), family aggression (partner aggression toward mother and partner aggression toward child), maternal distress (global distress and posttraumatic stress disorder symptoms), and early child behavior problems (internalizing and externalizing). Bivariate correlations indicated that CV, maternal distress, and early child behavior problems were significantly intercorrelated. A series of structural equation models was specified to estimate the direct and indirect effect of CV on early child behavior problems. A direct model indicated a significant path from CV to early child behavior problems, after controlling for maternal SES and family aggression. The direct CV-early child behavior problems path diminished, however, when maternal distress was included in the model, after controlling for maternal SES and family aggression. Results are consistent with a mediation model of the impact of maternal distress symptoms on the link between CV and early child behavior problems.
本研究探讨了母亲的困扰如何在接触社区暴力(CV)与幼儿行为问题发展之间的联系中起中介作用。研究对象为160名年龄在3.0至5.11岁之间、居住在高犯罪率社区的儿童。采用结构方程模型构建潜在变量以识别模型组成部分:母亲的社会经济地位(SES)和公共援助状况、接触CV(母亲对当地暴力、社会混乱和犯罪恐惧的认知;以及儿童目睹暴力事件的频率)、家庭攻击行为(伴侣对母亲的攻击和伴侣对儿童的攻击)、母亲的困扰(总体困扰和创伤后应激障碍症状)以及幼儿行为问题(内化和外化问题)。双变量相关性表明,CV、母亲的困扰和幼儿行为问题之间存在显著的相互关联。指定了一系列结构方程模型来估计CV对幼儿行为问题的直接和间接影响。一个直接模型表明,在控制了母亲的SES和家庭攻击行为后,从CV到幼儿行为问题存在一条显著路径。然而,在控制了母亲的SES和家庭攻击行为后,当模型中纳入母亲的困扰时,CV与幼儿行为问题之间的直接路径减弱。研究结果与母亲困扰症状对CV与幼儿行为问题之间联系的中介模型一致。
