Postpartum Depressive Disorder

This is a study evaluating the efficacy, and safety of KH607 in 72 participants diagnosed with Postpartum Depressive Disorder.

The goal of this clinical trial is to determine if the Powerly app can help prevent postpartum depression and anxiety in healthy pregnant women. The main questions it aims to answer are: * Does the Powerly app reduce postpartum depression and anxiety? * Does it improve emotion regulation and maternal bonding with a child? Researchers will compare two groups: one using the Powerly app and the other receiving care as usual (CAU) to see if the app leads to better mental health outcomes. Participants will: * Use the Powerly app for four weeks (if in the intervention group). * Complete mental health assessments before the study, after four weeks, and six weeks postpartum.
