PPD ACT: an app-based genetic study of postpartum depression

Area of Science:

• Reproductive Psychiatry
• Genetics
• Digital Health

Background:

• Postpartum depression (PPD) is a common childbirth complication, making it suitable for genetic research.
• Existing research is limited by sample size and homogeneity challenges.
• Genetic studies are crucial for understanding PPD's underlying mechanisms.

Purpose of the Study:

• To develop and deploy a mobile application (PPD ACT) for recruiting, consenting, and collecting DNA from women with a history of PPD.
• To facilitate large-scale genome-wide association studies (GWAS) for PPD.
• To establish a robust and scalable platform for international PPD research.

Main Methods:

• Development of an iOS application (PPD ACT) for participant interaction and data collection.
• Recruitment of 7344 women with a history of PPD and biobanking of 2946 DNA samples.
• Clinical validation and recall validity assessments to ensure data reliability.

Main Results:

• Successfully recruited a large cohort of PPD cases, with samples collected within two years of their most severe episode.
• Demonstrated the app's capability for efficient participant recruitment, consent, and DNA sample collection.
• Validated the reliability of screening tools through clinical validation and long-term recall assessments.

Conclusions:

• The PPD ACT mobile app is an effective tool for large-scale genetic research in postpartum depression.
• Multidisciplinary collaboration is essential for the successful implementation of such digital health research initiatives.
• The PPD ACT platform is adaptable for international deployment to create a global PPD research cohort.
