ABSTRACT

This study, using longitudinal data from the South African Birth to Twenty Plus study, assessed associations between early childcare quality in the home between six months and two years, household SES and cognitive development at age 5. Childcare quality was assessed using measures of maternal responsiveness and cognitive stimulation. Cognitive development at age 5 was assessed using the Revised Denver Pre-screening Developmental Questionnaire (R-DPDQ). Bivariate analysis and multiple linear regressions were conducted. The analytical sample comprised 856 mother–child pairs. Quality of care in the home differed significantly according to SES status, with more children in the low SES group receiving low quality of care. There was no association between childcare quality and cognitive development. There were differences in the cognitive development scores of children in different socio-economic groups; high levels of cognitive stimulation in the home were associated with increased R-DPDQ scores for children in the low SES group.

摘要

这项研究使用了从南非出生到20年代研究的纵向数据，评估了六个月至两年之间家庭早期儿童保育质量，5岁时的家庭SES与认知发展之间的关联。和认知刺激。使用修订的丹佛预筛查发育问卷（R-DPDQ）评估5岁时的认知发育。进行了双变量分析和多元线性回归。分析样本包括856对母子。根据SES的状态，家庭中的护理质量显着不同，低SES组中的更多儿童接受的护理质量较低。育儿质量与认知发展之间没有关联。不同社会经济群体儿童的认知发展得分存在差异；低SES组儿童在家中认知刺激水平高与R-DPDQ得分升高有关。
