Evaluation of the Pregnancy to Parenthood program: A dyadic intervention for mothers with perinatal mental disorders and their infants.

Dyadic interventions targeting maternal mental health and the mother-infant relationship in the perinatal period are critical due to the potential consequences of perinatal mental illness and relational disturbance for the mother, the infant, and their family. This paper describes the Pregnancy to Parenthood (P2P) model of care, a dyadic mother-infant community-based program designed to support vulnerable families in Western Australia in the context of an identified need to build workforce capacity. A pragmatic service evaluation study was conducted by analyzing routine clinical data collected from 105 dyads who completed pre- and post-intervention measures, including the Edinburgh Postnatal Depression Scale (EPDS), Perinatal Anxiety Screening Scale (PASS), and the Mother Object Relations Scale-Short Form (MORS-SF).
