Early language development supports cognitive, academic, and behavioral success. Identifying modifiable predictors of child language may inform policies and practices aiming to promote language development.
To synthesize results of observational studies examining parenting behavior and early childhood language in typically developing samples.
Searches were conducted in Medline, Embase, PsycINFO, Web of Science, and Dissertation Abstracts (1967 to 2017).
Studies had 1 of 2 observational measures of parenting behavior (i.e., sensitive responsiveness or warmth) and a measure of child language.
Data from 37 studies were extracted by independent coders. Estimates were examined by using random-effects meta-analysis.
Two meta-analyses were conducted, which examined (1) the association between sensitive-responsive parenting and child language ( = 36; = 0.27; 95% confidence interval: 0.21 to 0.33); and (2) the association between parental warmth and child language ( = 13; = 0.16; 95% confidence interval: 0.09 to 21). The pooled effect size for the association between sensitive responsiveness and child language was statistically higher than that of warmth and child language. The association between sensitive responsiveness and child language was moderated by family socioeconomic status (SES): effect sizes were stronger in low and diverse SES groups compared with middle to upper SES groups. Effect sizes were also stronger in longitudinal versus cross-sectional studies.
Results are limited to typically developing samples and mother-child dyads. Findings cannot speak to causal processes.
Findings support theories describing how sensitive parenting may facilitate language and learning.
早期语言发展有助于认知、学术和行为的成功。识别可改变的儿童语言预测因素可以为旨在促进语言发展的政策和实践提供信息。
综合观察性研究的结果，这些研究检查了在正常发育的样本中父母行为与儿童早期语言之间的关系。
在 Medline、Embase、PsycINFO、Web of Science 和 Dissertation Abstracts（1967 年至 2017 年）中进行了搜索。
这些研究有 1 种观察性的父母行为测量（即敏感反应或温暖）和 1 种儿童语言测量。
由独立的编码员提取 37 项研究的数据。使用随机效应荟萃分析检查估计值。
进行了 2 项荟萃分析，考察了（1）敏感反应性养育与儿童语言之间的关联（ = 36； = 0.27；95%置信区间：0.21 至 0.33）；以及（2）父母温暖与儿童语言之间的关联（ = 13； = 0.16；95%置信区间：0.09 至 21）。敏感反应性与儿童语言之间的关联的汇总效应大小在统计学上高于温暖与儿童语言之间的关联。敏感反应性与儿童语言之间的关联受到家庭社会经济地位（SES）的调节：在低 SES 和多样化的 SES 群体中，效应大小比中高 SES 群体更强。在纵向研究与横断面研究中，效应大小也更强。
结果仅限于正常发育的样本和母子二人组。研究结果不能说明因果过程。
研究结果支持描述敏感育儿如何促进语言和学习的理论。
