A Randomized Controlled Trial to Improve Mother-Infant Synchrony Among Women With Childhood Adversity
In Brief
A clinical study evaluating ATVV and Attention control for Parent-Child Relations and 2 related conditions. Completed, enrolled 262 participants across 2 sites.
Detailed Summary
Childhood adversity affects almost two-thirds of the US population, is a major risk factor for the leading causes of disease and increases US economic health burdens. Childhood adversity also alters biologic systems, such as the oxytocin hormone, that can affect attachment behavior. This innovative study has the potential to advance science and improve mother-infant interaction by testing an early life, home-based, multisensory behavioral intervention (called ATVV), targeting the oxytocin system, to promote synchronous early mother-infant interaction, especially critical for mothers who have experienced childhood adversity. This two-group randomized clinical trial will test the ATVV's effect on oxytocin system function and quality of mother-infant interaction. The investigators will enroll 250 first-time healthy mothers carrying a single baby who have a history of childhood adversity, and obtain baseline data in their third trimester of pregnancy. Soon after birth (before hospital discharge), mothers (and babies) who continue to be eligible are randomized into the intervention group and taught to give ATVV daily for 3 months, or randomized into the Attention Control education group and taught safe infant care. After birth, the investigators check-in frequently with mothers through weekly phone calls. There are 3 study visits at 1, 2 and 3 months after birth that include survey questions and collection of maternal blood and infant saliva. Mothers and babies are also video-recorded at 3 months after birth for 4 minutes to assess mother-infant interaction. The investigators follow-up with a phone call at 6 months after birth. While both groups will benefit from the content and attention the investigators give mothers, the investigators hypothesize that, compared to the education group, mothers and infants in the intervention group will have improved oxytocin system function and more synchronous mother-infant interaction.

Timeline
Interventions
A 15-minute behavioral intervention that mothers administer once daily to their infant for 3 months providing Auditory, Tactile, Visual, and Vestibular (ATVV) stimulation. Multisensory stimuli are presented in gradual progression. Mother-infant engagement is attempted throughout ATVV so that mothers learn to identify, interpret and adapt to their infants cues. ATVV can be given without eye to eye gaze making it appropriate for newborns. ATVV is offered contingent on infant cues to promote self-regulation and withdrawn if any persistent disengagement cues. Mothers are taught how to adapt ATVV as their infant grows. Fidelity to the intervention is checked with weekly phone calls and monthly study visits. Mothers also receive a daily text from REDCap to document an intervention frequency log.
Mothers in the Attention Control group receive a similar amount of daily texts, weekly phone call and in-person study visit attention as mothers in the ATVV group, but with distinctly different content. Over the first 3 postnatal months, mothers learn safe infant-care that includes content on diapers, infant clothing, blankets, infant care including bathing, sleep positions, sleep habits, holding the baby, safety of infant equipment, breastfeeding, formula, and age appropriate toys.
