For infants/toddlers experiencing social communication difficulties, parent-mediated interventions (PMI) are the current field standard to promote development within a natural context. Previous research highlights the importance for parents to scaffold language learning opportunities beyond clinical settings to maximize children’s potential. However, for infants/toddlers exhibiting social communication-based difficulties currently enrolled in a family routines-based PMI, less is known about the individual contributions of communication between child and parent in order to promote optimal language development.
The present study expands our understanding of children’s communication by examining whether (1)children exhibit language impairments at enrollment; (2)whether observed mother-child communication during play increases following an eight-session intervention; and (3)associations between children’s language impairments and observed communication. As part of an ongoing PMI, 16 children were assessed with the Mullen Scales of Early Learning (MSEL) at enrollment to index their receptive (RL) and expressive language (EL) skills. Home visit recordings of play-based interactions were rated for child EL use (e.g., single words; two-word phrases) and mothers’ language-learning opportunities (i.e., symbol highlighting). Overall, children on average received MSEL-RL and MSEL-EL scores within the concerns range for their age. A series of repeated measures ANCOVAs to assess communication during play were conducted and revealed a significant increase in child EL use, F(1,15)=5.87,p=.03. To examine associations between children’s MSEL scores and play-based observations, a series of partial correlations were conducted. No significant associations were observed. In sum, these findings highlight the importance of monitoring language development and the modest impact of an 8-week PMI on children’s language use.
