Methods: This study employs a longitudinal, randomized, pre and post-test design. A convenience sample of 576 couples will be recruited at antenatal clinics and randomly assigned to one of three groups: (1) the experimental group with both couples receives the intervention on top of usual perinatal care; (2) the comparison group with only the women receives the intervention on top of usual perinatal care; and (3) the control group receives usual perinatal care only. The intervention consists of a single 3-hour session during pregnancy and two telephone follow-up at postpartum week one and week two. Primary outcome on postnatal depression will be assessed by Edinburgh Postnatal Depression Scale. Secondary outcomes on marital relationship and quality of life will be assessed by Dyadic Adjustment Scale and Medical Outcomes Study Short Form 12-item Health Survey, respectively, at baseline, 6 weeks, 6 months and one year postpartum. Process evaluation will be conducted at 6 weeks postpartum using individual telephone interview on 20 couples randomly selected from the experimental group.
