Using the LENA System in Early Intervention - b

This project will determine whether an intervention to enhance communication between infants and toddlers with developmental disabilities and their depressed mothers can be integrated into federally-funded Early Intervention (EI) services. Participants will be mothers with depressive symptoms whose children are receiving EI services, along with their EI service providers. The investigators will conduct a small feasibility trial using the Language ENhancement Assessment/intervention system (LENA), a technology-supported language monitoring system, with 10 mothers and one of their child's EI service providers. The LENA uses an infant or toddler garment with an integrated audiotape system that records adult speech centered on the child, child vocalizations, and reciprocal parent-child turn-taking conversations. The LENA software produces visual feedback that a mother can use to focus her language interactions with her child. They study will follow participants in the LENA with feedback intervention over 6 weeks: 5 weeks of LENA data collection (with mothers running the system 1 day/week for 16 consecutive hours). The investigators will analyze data from measures on LENA communication data (adult word count, child vocalizations and conversational turn-taking), and measures of child language, maternal depressive symptoms, and child disability profiles.
