PACT Consortium is conducting a study to understand more about the causes of postpartum depression and postpartum psychosis in order to develop new and better treatments. We need as much information as possible from women who have experienced postpartum depression and postpartum psychosis in order to find and analyze patterns. We have created an app that will aid us in this data collection.

The PPD ACT app is currently available on iOS devices in Australia, Canada and the US and on Android devices in Australia and the US. You can find PPD ACT in the App Store and Play Store in English and in Spanish. Coming soon to the UK and to Denmark.

About the PPD ACT App

The app will be a way for us to collect information for the study, which has two parts.

Part 1: We will use the app to ask you questions about childbirth and mood and anxiety symptoms that happened after you gave birth.

You will be given feedback about your responses to the questions. We can point you toward doctors in your area who specialize in evaluating and treating women with postpartum depression.

Part 2: Some women will be asked to give a saliva sample. These women will be sent a kit in the mail. Collecting saliva is just spitting in a tube, and can be done in your home. The sample gets sent back by mail. We can get DNA from your saliva, and will use it to "scan" your DNA. If we do this for tens of thousands of women, we can identify the genetic differences in women who got postpartum depression. This will allow us to develop new treatments.
You may qualify for the study if you are a woman over 18 and have experienced either of the following:


  • Postpartum depression (PPD) is the leading cause of maternal morbidity and mortality and is a critical public health threat around the world.

  • Common symptoms include feeling sad or depressed, difficulty concentrating, ruminating thoughts, excessive worry about baby's health, lack of enjoyment in the baby, and suicidal thoughts.

  • PPD afflicts one in seven women and has serious consequences for children and families.

  • Research into the causes of PPD has been dismally underfunded.


  • Postpartum psychosis (PPP) is a rare but severe postpartum mood disorder that has rapid onset of symptoms within the first days to weeks postpartum.

  • Women can experience delusions, hallucinations, and bizarre behavior along with mania.

  • Sleep disturbance is also very common. If postpartum psychosis goes untreated, it is associated with devastating consequences to mother and baby.

We do not have a complete understanding of the causes of PPD and PPP and cannot predict who is at risk. We urgently need this knowledge to improve the detection, prevention, and treatment of PPD and PPP.

Please feel free to email us at pact.questions@med.unc.edu if you have further questions or if you would like more information.
