The present study investigated whether a distance-delivered intervention could significantly decrease mild to moderate postpartum depression (PPD) in mothers as compared to usual care. Mothers with PPD (n = 62) were randomly assigned to the intervention or standard community care. Participants receiving the intervention followed a 12-session cognitive behavioural informed handbook supplemented with telephone-based coaching support. Diagnostic status and depressive symptoms were assessed at baseline and 3, 6 and 12 months postrandomization. Odds ratios indicated that intervention group participants were 1.5 times as likely to experience diagnostic remission at 3 months (mid-intervention) (p = 0.742), 1.54 times as likely at 6 months (p = 0.696) and 12.5 times as likely at 12 months (p = 0.009). Intervention 'dosage' significantly moderated this effect; for every additional coaching session completed, individuals had a 1.4 times greater chance of showing improvement at 3 and 6 months. Mothers reported high satisfaction with the intervention. Findings suggest positive outcomes at each time point and superior outcomes to the control condition at the long-term follow-up. Caution in interpreting these results is warranted due to small sample size and incomplete data; however, they support further investigation into the use of distance interventions as an accessible and effective solution for women with PPD.
