Official title
Enhancing Communication Between Children in EI and Their Depressed Mothers
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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 randomized control trial using the Language ENhancement Assessment/intervention system (LENA), a technology-supported language monitoring system, with 20 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. A "LENA with feedback" group will follow participants in the intervention over 5 weeks: 5 weeks of LENA data collection (with mothers running the system 1 day/week for 16 consecutive hours), with feedback during 3 weeks (baseline=LENA, no feedback; 3 week intervention=LENA with feedback; post-intervention=LENA, no feedback). A "LENA no feedback" group will complete LENA data collection at baseline on the same schedule but will not receive feedback. The main difference between groups will be provision of LENA feedback and strategies to promote increased mother-child interactions. This design allows the investigators to isolate the effect of LENA with feedback, and minimizes attributing changes in language environments due to exposure to LENA alone. 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.
