Effect of couple-based cognitive behavioural intervention on prevention of postnatal depression: multisite randomised
Objective:
To compare a couple-based cognitive behavioural intervention (CBI) for postnatal depression with CBI delivered to women alone and control (standard perinatal care).
Design:
Multisite randomised controlled trial.
Setting:
Antenatal clinics at three regional public hospitals in Hong Kong.
Sample:
388 low-risk childbearing couples.
Methods:
Childbearing couples were randomly allocated to couple-based CBI (n = 134), women-alone CBI (n = 124) or control (n = 130). The CBI consists of a 3-hour antenatal group session and two 30-minute postnatal telephone follow-up sessions.
Main Outcome Measures:
The primary outcome was depressive symptoms, measured on the Edinburgh Postnatal Depression Scale (EPDS). Assessments were collected at baseline (during pregnancy), 6 weeks, 6 months, and 12 months postpartum.
Results:
Depressive symptoms were significantly more improved at 6 weeks postpartum for mothers in couple-based CBI than in women-alone CBI (difference 1.46, 95% CI 0.11-2.81) or control groups (difference 1.71, 95% CI 0.29-3.13). The proportion of mothers with postnatal depression (EPDS score ≥ 10) was significantly lower at 6 weeks postpartum in couple-based CBI than in control (difference 17.8%, 95% CI 3.6-32.0). However, the treatment effect was not maintained at 6 and 12 months. There was no significant intervention effect among fathers.
Conclusions:
Couple-based CBI is more effective than CBI delivered to mothers alone and standard perinatal care in reducing the incidence of postnatal depression among Chinese mothers in the early postpartum period.
Tweetable Abstract:
Couple-based cognitive behavioural intervention is effective in reducing postnatal depression among Chinese mothers in the early postpartum period.

The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
