Effect of Telephone-Based Support on Postpartum Depression: A Randomized Controlled Trial

Postpartum depression (PPD) is one public health issue that affects both maternal and child health. This research studies the effect of health volunteers’ telephonebased support on decreasing PPD. This randomized controlled trial evaluated 203 women who had uncomplicated deliveries. The women completed the Edinburg Postnatal Depression Scale (EPDS), 10 to 15 days after childbirth in order to be assessed for pre-trial depression scores. The cut-off point for depression was considered to be a score of >10. We randomly assigned 54 eligible mothers (n=27 per group) with mild and moderate depression to the intervention and control groups. In both groups, mothers received routine postpartum care. The intervention group additionally received telephone support from health volunteers. A questionnaire was used to gather demographic and obstetric information. By the end of the 6th week, mothers completed the EPDS to be reassessed for depression after intervention. Data were analyzed using the chi-square, Fisher’s exact, t- and paired t tests. The mean depression scores before intervention (10 to 15 days after childbirth) in the intervention and control groups did not significantly differ (P=0.682). Depression scores of the intervention and control groups showed a significant difference after 6 weeks (P=0.035). In addition, there was a significant decrease in depression for the intervention and control groups (P=0.045). Health volunteer telephone-based support effectively decreased PPD and may be beneficial to women with symptoms of mild and moderate PPD (Registration number: IRCT201202159027N1).
