In this review article, meta-analysis was used to summarize research investigating language skills in maltreated children.
A systematic search of published studies was undertaken. Studies were included in the meta-analysis if they investigated language skills in groups comprising maltreated and nonmaltreated children. Studies were selected if these 2 groups of children were of comparable age and from a similar socioeconomic background.
A total of 26 studies were identified that met the inclusion criteria. Results from the meta-analysis showed that maltreated children demonstrated consistently poorer language skills with respect to receptive vocabulary (k = 19; standardized mean difference [SMD] = .463; 95% confidence interval [CI; .293, .634]; p < .001), expressive language (k = 4; SMD =.860; 95% CI [.557, 1.163]; p < .001), and receptive language (k = 9; SMD =.528; 95% CI [.220, .837]; p < .001).
Together, these results indicate a reliable association between child maltreatment and poor language skills.
在这篇综述文章中，采用荟萃分析来总结关于受虐待儿童语言技能的研究。
对已发表的研究进行了系统检索。如果研究调查了包括受虐待儿童和未受虐待儿童的群体的语言技能，则将其纳入荟萃分析。如果这两组儿童年龄相当且来自相似的社会经济背景，则选择这些研究。
共确定了26项符合纳入标准的研究。荟萃分析结果表明，受虐待儿童在接受性词汇（k = 19；标准化平均差[SMD] =.463；95%置信区间[CI;.293，.634]；p <.001）、表达性语言（k = 4；SMD =.860；95% CI [.557，1.163]；p <.001）和接受性语言（k = 9；SMD =.528；95% CI [.220，.837]；p <.001）方面始终表现出较差的语言技能。
总之，这些结果表明儿童虐待与语言技能差之间存在可靠的关联。
