Postpartum depression (PPD) is a major public health issue. Known as "the thief that steals motherhood" since symptoms obstruct a mother's capacity for understanding and enjoying her baby, PPD affects approximately 1 in 5 moms. Built via "serve and return" interactions (e.g. baby smiles, mom smiles back), sensitive and responsive exchanges are the foundation for healthy child development but are diminished by PPD, resulting in interactions that place children at risk for behavioural and cognitive problems. Infants perceive PPD as stressful; stressors stimulate the brain's hypothalamic pituitary adrenal axis (HPA) and trigger stress hormone (cortisol) release, which, in turn, negatively affects developing infant brains by decreasing brain volume. Infants' critical periods of brain development are vulnerable to long-term effects of cortisol, explaining some of the problematic developmental outcomes observed in children of depressed mothers. How can we support depressed mothers and their infants? Successfully treating PPD does not always benefit mother-child relationships; however, this research builds on a successful pilot that demonstrated that nurse-guided video feedback improved mother-infant interactions in the context of PPD. By improving interaction quality, depressed mothers may be motivated to engage in more play and, in turn, infants who appear interested and ready to interact are more likely to elicit positive, enjoyable experiences from mothers. Building on the pilot, we will trial the effectiveness of VID-KIDS (Video-Feedback Interaction Guidance for Improving Interactions Between Depressed Mothers and their Infants) on maternal-infant interaction and infant cortisol patterns as well as infant development, maternal symptoms of depression and anxiety, and parenting self-efficacy. If successful, future aims are to 1) integrate VID-KIDS into existing services of Calgary Public Health; and 2) commercialize VID-KIDS for dissemination.
