本研究探讨了母亲的痛苦如何介导暴露于社区暴力（CV）和早期儿童行为问题的发展之间的联系。研究对象是160名居住在高犯罪率社区的儿童，年龄在3.0到5.11岁之间。使用结构方程模型，构建潜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，CV暴露（母亲对当地暴力、社会混乱和犯罪恐惧的看法;和儿童共同目睹暴力事件的频率）、家庭攻击（伴侣对母亲的攻击和伴侣对孩子的攻击），母亲的痛苦（全球性痛苦和创伤后应激障碍症状）和早期儿童行为问题（内化和外化）。双变量相关性表明，CV，母亲的痛苦，和早期儿童的行为问题显着相关。一系列的结构方程模型被指定来估计CV对早期儿童行为问题的直接和间接影响。一个直接的模型表明，一个显着的路径从CV到早期儿童行为问题，母亲SES和家庭攻击控制后。然而，在控制了母亲的社会经济地位和家庭攻击后，当母亲的痛苦被纳入模型时，直接的CV-早期儿童行为问题路径减少了。结果与产妇痛苦症状对CV和幼儿行为问题之间联系的影响的中介模型一致。
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.
