Intervention: Edinburgh Postnatal Depression Scale
Description: The Edinburgh Postnatal Depression Scale (EPDS) is a 10-item self-administered survey that screens for symptoms such as feelings of guilt, sleep disturbance, reduced energy levels, anhedonia and suicidal ideation that have been present during the 7 days preceding its administration. Each question is scored on a 4-point scale ranging from 0 to 3 points. Overall scores between 10 and 12 points suggest increased risk for depression; scores of 13 points or above indicate that the diagnostic criteria for major depression disorder have probably been met. In addition, item 10 deals with suicidal thoughts. The EPDS is a valid and reliable tool for identifying women at risk of depression, both during pregnancy and postpartum, and is sensitive to changes in the severity of depression over time.
