Are you interested in the PENGuIN Study?

The purpose of the study is to learn more about changes to thinking, feeling, and the brain during and after pregnancy and how that may affect the way individuals respond to their infants. We want to learn more about these changes in parents with and without opioid use in order to better support parents throughout the postpartum period.

You may be eligible to participate in the Parents Engaging Infants (PENGuIN) Study at Oregon Health & Science University if:

  • You are pregnant
  • You are between 21 and 50 years old

If eligible for the study, your participation would involve completing tasks that have to do with your thinking and feeling, questionnaires, interviews, biological sample collection (hair, saliva, nail, urine, and blood), and may include an MRI scan. The MRI scan would be done postpartum and not during pregnancy. MRI does not involve any radiation, sedation, or injections and is safe for all ages.

What is being studied?

The purpose of the study is to learn more about how thinking, feeling, and the brain may change during pregnancy and after pregnancy and how these changes may affect how parents interact and engage with their infants.

How long is the study?

Study activities you are eligible to complete would last approximately:

  • 20-25 minutes for the online screen
  • 3 hours 45 minutes – 4 hours 45 minutes for the 3rd Trimester Visit
  • 2 hours 45 minutes – 3 hours 45 minutes for 6 Week Postpartum Visit (Optional MRI Scan OR Computerized Tasks additional 1-3 hrs.)
  • 5-6 hours for 6 Month Postpartum Visit
  • 5-6 hours for 12 Month Postpartum Visit

What will my participation involve?

If interested, you will complete the quick, online screener. If you might be eligible for the study, we will offer to schedule you for a pregnancy visit. Your pregnancy visit will involve answering online questionnaires, completing a psychiatric interview (remotely via video conferencing), online computer tasks, and a small collection of blood, nail, urine, and hair samples. This visit will allow us to confirm eligibility criteria for your participation in postpartum visits, which will include the optional MRI, questionnaires, psychiatric interviews, tasks with your baby, and a small collection of blood, urine, nail, and hair samples.

If I participate, do I have to do the MRI?

No, we will only invite a participant to complete an MRI scan if they are interested and it is safe for them to have an MRI.

What does the MRI Session entail?

You will be asked to complete a MRI scanning session 6 weeks after your baby is born. During the MRI, you will lie quietly inside the center of a large, doughnut shaped magnet for about 70 minutes. You will be made as comfortable as possible by padding the neck, shoulders, head, and knees with special pillows. While in the scanner, you will do three different tasks that involve looking at numbers, letters, and shapes and pushing buttons.

Will I be compensated for participating?

You would receive the following for study activities you are eligible to complete:

  • $10 for an online screening
  • $75 for 3rd trimester Visit
  • $80 for 6 Week Postpartum Visit
    • $100 for an MRI Scan* at 6 Weeks Postpartum or
    • $30 for in person computerized tasks
  • $135 for 6 Month Postpartum Visit
  • $155 for 12 Month Postpartum Visit
  • $50 bonus for completion of all postpartum visits

*Eligible participants will be invited to complete an MRI Scan at their 6 Week Visit if an MRI would be safe.

You may receive up to $605 for completing the study.

Can you pay for my transportation?

Researchers will provide you with courtesy parking. If you need assistance getting to your visits, researchers will provide bus fare or arrange for other transportation.

What if I change my mind and don’t want to participate?

That’s fine! If you get a call from a researcher, just tell them you don’t want to participate and they will not contact you again.
