About this study
Official title: Real-life Implementation Randomized Clinical Trial Assessing Effectiveness of Powerly - Science-based Digital Intervention Preventing Postpartum Depression and Anxiety
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.
Read the detailed description
Pregnancy is a period of significant emotional and physical changes, with up to 30% of expecting mothers experiencing high stress. After birth, around 15-20% of new mothers suffer from postpartum depression, and 25-35% experience anxiety. Despite broad availability of mobile apps aimed at these challenges, none of them have been rigorously tested through clinical studies. To fill this gap, we developed Powerly, a science-based mobile app designed to help prevent postpartum depression and anxiety.
In this study, 140 healthy pregnant women will be randomly assigned to one of two groups: one will use the Powerly app for four weeks, while the other will receive care as usual (CAU). Powerly is grounded in cognitive behavioral therapy (CBT) and personalized to the individual's needs, with input from healthcare professionals and pregnant women. We will collect information on participants\' mental health at three points: before they start using the app, after four weeks of app use / CAU, and six weeks after giving birth. The app's effectiveness will be evaluated by examining improvements in mental health outcomes, such as reduced rates of postpartum depression and anxiety, better emotion regulation, and stronger maternal bonding with a baby.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PowerlyBehavioural
Powerly is a mental well-being mobile app, in which pregnant women can track their mood and level of stress, and receive personalized psychological modules to increase their mental health and well-being. By integrating evidence-based content and cognitive behavioral techniques with insights from pregnant and postpartum individuals and health professionals, Powerly offers a comprehensive psychological support including reappraisal, mental imagery, gratitude, mindfulness, self-efficacy and behavioral activation exercises.
| Study group | Role | What they receive |
|---|---|---|
| Intervention - Powerly | Experimental | Participants in the intervention group will complete baseline questionnaires and receive instructions on how to download Powerly. They will use the app daily for 28 days, at least once per day, and will be invited to complete the questionnaires again, and once more six weeks postpartum. Receives: Behavioral: Powerly |
| Care as usual | No intervention | Participants in the CAU group will complete baseline questionnaires and be informed that they will receive access to Powerly six weeks postpartum. They will be invited to complete the questionnaires again 28 days later, and once more six weeks postpartum. |

Measured: Collected only at first follow-up measurement after 4 weeks of study
MFA (Maternal-Fetal Attachment Scale)
the 24-item scale evaluates the bond between mother and fetus during pregnancy. It includes questions about interactions with the fetus, attributing characteristics to the fetus, and role-taking, among others
Measured: From baseline measurement until first follow-up measurement after 4 weeks of study
GSE (General Self-Efficacy Scale)
it evaluates an individual optimistic self-belief in their capability to handle difficult tasks, challenges, and adversities, through 10 items
Measured: From baseline measurement until the second follow-up measurement at 6 weeks postpartum
Adherence
the number of interactions with the app by each of the participants
Measured: Collected passively during app use period (4 weeks)
