Behavioral Change in the Mother/Infant Dyad: Preventing Postpartum Depression

DESCRIPTION (provided by applicant): Of the over 4 million live births each year in the United States, nearly 800,000 - or 20% - of the mothers will develop major or minor depression within the first 3 months postpartum. This number dwarfs prevalence rates for gestational diabetes (2-5%) and preterm birth (12.7%). Existing clinical approaches to postpartum depression (PPD) use standard pharmacologic and psychological interventions to reduce women's symptoms. Nevertheless, PPD is undertreated, in part because women are reluctant to seek treatment due to stigma associated with mental health care and disinclination to take psychotropic medications when breastfeeding. The consequences of this are substantial. Untreated PPD is associated with diminished quality of life and significant emotional suffering for women, and, through compromised caregiving, poor outcomes in children's cognitive and social-emotional development. Although maternal risk factors for PPD are well known, protocols for prevention based on commonly used depression interventions are only beginning to be evaluated. Building on developmental data showing the profound bi-directionality of emotional and behavioral influences between mother and infant, we propose testing a novel PPD intervention protocol that challenges the standard, individually-focused treatment paradigm. Our intervention is based on the conceptualization of PPD as a potential disorder of the dyad, and one that can be approached through behavioral change in and affective engagement with mother and child. Studies show that infant cry/fuss and sleep behavior are associated with PPD, and that parenting interventions can change infant behavior, yet these findings have never been applied to PPD. In this R21 application, we aim to collect pilot and feasibility data on a novel PPD risk-reducing protocol based on a dyadic behavioral approach to PPD in which we treat at-risk women by promoting maternally-mediated behavioral changes in their infants. We will select a sample of pregnant women at risk for PPD, teach parenting skills to increase infant nocturnal sleep and reduce fuss/cry behavior to half of the sample during 3 perinatal visits, then evaluate infant behavior at 6 and 14 weeks, and maternal mood at 6, 10, and 14 weeks postpartum. In line with NIMH's strategic goal to develop an integrative understanding of basic brain-behavior processes, we will fully exploit the investigative opportunities of this intervention study by using state-of-the-art EEG and fetal monitoring to characterize early biomarkers associated with infant behavior and behavior change. Our proposal has the potential to have a major impact on clinical research, and to transform the standard care of PPD in that (1) the intervention will have high rates of treatment compliance because (a) the protocol sessions can be incorporated into usual perinatal medical visits, (b) parenting skills will appeal to women as a non-psychiatric intervention, (c) the clinical approach will have face validity given the dyadic focus of the perinatal period; (2) its aim is prevention; (3) it fosters both maternal and child well being; (4) it will expand the risk factors for PPD to include neurobehavioral markers in the perinate. PUBLIC HEALTH RELEVANCE: Postpartum depression (PPD) is undertreated and the consequences of this are substantial for women and children. Studies show that infant cry/fuss and sleep behavior are associated with PPD, and that parenting interventions can change infant behavior, yet these findings have never been applied to PPD. We propose teaching parenting skills to increase infant nocturnal sleep and reduce fuss/cry behavior to women likely to develop PPD to see if we can prevent the onset of this disorder.
