Summary

The TMW intervention aims to foster parental behaviors that facilitate children's language emergence at a critical developmental stage, and thus will be implemented at 13-16 months of age. The investigators hypothesize that the primary effects of the TMW Intervention will significantly 1) improve low-SES parents' understanding of the importance of parent language in a child's development, 2) increase parents' linguistic interaction, responsiveness, and overall engagement with their children, and 3) increase children's language output, as measured through LENA (child vocalization count, conversational turn count), coded video interaction (number of types, tokens and utterances for both children and adults), audio recordings from The Three T's application during the video sessions, and a battery of assessments targeting linguistic and cognitive development. Furthermore, the investigators hypothesize that increased parental interaction will result in 4) an improvement in children's socioemotional development as assessed by the Social Emotional Ages and Stages Questionnaire (ASQ-SE). Finally, the investigators hypothesize that these socioemotional and linguistic gains through early development, along with sustained increased parental engagement, will be expressed in 5) increased child school readiness upon kindergarten entry as assessed by Woodcock-Johnson Psycho-Educational Battery (WJ).

Added 2023: an 8th child-assessment, parent/child interaction video session, and parent surveys have been added with the original sample to measure long-term outcomes of children whose parents participated in the home visiting intervention.
