This capstone project describes the mental health of mothers during the perinatal period. It provides a review of disorders that occur during the perinatal period, from conception through 12 months after childbirth, with a particular focus on depression. In addition to focusing on depression, it also describes postpartum flourishing, a term coined by Aurelie Athan (2011). This capstone also describes interventions that can be utilized to decrease depression as well as interventions to increase the mental well-being and flourishing of new mothers during pregnancy and the postpartum period. Investing in the well-being of new mothers and helping new mothers to flourish has the potential to have a positive impact on the well-being of the infant and the well-being of the family.
