Can a phone app shield new mothers from postpartum depression?

This trial is testing whether a smartphone app called M.Bapp, which delivers cognitive behavioral therapy, is a feasible and acceptable way to prevent postpartum depression in mothers at high risk. The study will enroll pregnant women who are at least 32 weeks along and have no recent history of depression or anxiety. Participants will be randomly assigned to use M.Bapp or a standard parenting education app, and researchers will measure how many women use the app and how satisfied they are with it.
