Treatment as usual
PND
Participants randomized to the control arm attended the 5 sessions of the routine online educational group pregnancy classes facilitated by a designated nurse with no formal training in psychological interventions. The routine pregnancy classes during COVID-19 provided on-line access to education about pregnancy, birth, new-born care and included basic information about PND, and how to identify it and seek help. The women in the control arm were able to access all usual care and support offered by the participating hospitals.
