Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a randomized controlled trial to study a reading intervention in the NICU among preterm infants using LENA (Language Environment Analysis) recordings, linguistic feedback, and a language curriculum to improve the neonatal inpatient language environment and language outcomes for preterm infants.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This project aims to examine how an educational reading intervention in the NICU can impact preterm infant language development and examine the impact of reading on mother-infant autonomic systems. Investigators plan to determine the effects of parent reading in addition to standard caretaking and holding on preterm infants, between 23 to 31 weeks gestation hospitalized in the Women \& Infants NICU, on adult word count, infant vocalizations, conversational turns through audio recording obtained over 3 separate days when the infant is corrected to 32, 34 and 36 weeks. Investigators aim to determine the effect of parent reading on maternal and infant heart rate variability before, during, and after the shared reading intervention through video and a single channel electrocardiographic recording over the same 3 separate days as the LENA recording. Additionally, investigators aim to determine the effect of parent reading on maternal stress and perceived well-being in the NICU through a validated questionnaire and to determine parent satisfaction of a NICU reading intervention through a parent questionnaire completed prior to infant discharge and at the 12 month follow up visit. Secondary outcomes include determining the effect of parent reading on infant DNA methylation of the several genes through two saliva samples collected from the infant prior to study and post study enrollment and examine its relationship with infant stress and self-regulation based on a neurobehavioral exam performed at 36 weeks corrected age. Final outcomes include examination of the long-term effect of inpatient shared reading education on infant receptive and expressive language development at 12 and 24 months. Investigators hope this research will contribute to the growing research supporting early language development in preterm infants and its impact on maternal-infant well-being.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Language Intervention

1\. Review language and infant bonding curriculum 2. 1st LENA recording and heart rate variability of mother reading to infant 3. Provide LENA linguistic feedback and review curriculum 4. 2nd LENA recording and heart rate variability of mother reading to infant 5. Provide LENA linguistic feedback and review curriculum 6. 3rd LENA recording and heart rate variability of mother reading to infant 7. Provide LENA linguistic feedback

Assessments: 1. NICU Network Neurobehavioral Scale (NNNS) profile at 36 weeks 2. Fragile Infant Parent Readiness Evaluation at 36 weeks 3. Parent perception survey of reading and curriculum at 36 weeks and 12 months 4. Bayley Scales of Infant and Toddler Development at 12 and 24 months 5. DNA methylation of genes pre and post intervention

Group Type EXPERIMENTAL

Reading intervention

Intervention Type BEHAVIORAL

Written packet with 3 lessons. The first lesson includes how to begin to read and talk to their baby. The second lesson includes reading or talking about the day using parentese talk. The third lesson includes continuing to engage with the baby through interactive reading.

Infant bonding

Intervention Type BEHAVIORAL

Written packet with 3 lessons. The first lesson includes skin-to-skin and learning about their baby. The second lesson includes learning readiness cues and participation in feeding times. The third lesson includes developing routines and playing games.

LENA recording

Intervention Type BEHAVIORAL

The LENA device provide 16 hours of language recordings placed inside an infant vest. The recordings are uploaded to a computer which analyzes total adult word counts, infant vocalizations, conversational turns, background noise, and silence.

LENA linguistic feedback

Intervention Type BEHAVIORAL

LENA recordings of adult word counts, infant vocalizations, and conversational turns will be provided in printed form after each recording with review of each recording and progress over time.

Infant bonding

1\. Review infant bonding curriculum with mother 2. 1st LENA recording and heart rate variability of mother holding infant 3. Review infant bonding curriculum 4. 2nd LENA recording and heart rate variability of mother holding infant 5. Review infant bonding curriculum 6. 3rd LENA recording and heart rate variability of mother holding infant 7. Provide linguistic feedback of all 3 LENA recordings

Assessments: 1. NICU Network Neurobehavioral Scale (NNNS) profile at 36 weeks 2. Fragile Infant Parent Readiness Evaluation at 36 weeks 3. Parent perception survey of reading and curriculum at 36 weeks and 12 months 4. Bayley Scales of Infant and Toddler Development at 12 and 24 months 5. DNA methylation of genes pre and post intervention
