Do mothers' play behaviors moderate the associations between socioeconomic status and 24-month neurocognitive outcomes of toddlers born preterm or with low birth weight?

摘要

OBJECTIVE: We examined whether neonatal risks and maternal scaffolding (i.e., task changes and flexibility) during a 16-month post-term play interaction moderated the association between socioeconomic status (SES), visual-spatial processing and emerging working memory assessed at 24 months post-term among 75 toddlers born preterm or low birth weight. METHOD: SES and neonatal risk data were collected at hospital discharge and mother-child play interactions were observed at 16-month post-term. General cognitive abilities, verbalonverbal working memory and visual-spatial processing data were collected at 24 months. RESULTS: Neonatal risks did not moderate the associations between SES and 24-month outcomes. However, lower mother-initiated task changes were related to better 24-month visual-spatial processing among children living in higher SES homes. Mothers' flexible responses to child initiated task changes similarly moderated the impact of SES on 24-month visual-spatial processing. CONCLUSION: Our results suggest that mothers' play behaviors differentially relate to child outcomes depending on household SES.
