For Participants

• Provide Information about yourself, including contact information.
• Complete surveys and interviews concerning yourself and your child.
• Complete play activities with your child that are audio and video recorded.
• Provide urine, saliva, nail, and blood samples.

• Magnetic Resonance Imaging (MRI) at 4 study visits
  • MRI uses a strong magnet and a computer to create pictures of the brain
• Electroencephalogram (EEG) of your child’s brain at 3 study visits
  • EEG uses a cap that measures electrical activity of the brain while doing activities
• Wearing sensors to measure movement, sleep, and heart rate
• Complete measures of learning, memory, and behavior.
• Take a vision test.
• Have measurements of height, weight, head size at the study visits
• Give samples of urine, saliva, and stool

• Prior to your infants MRI scan, we will have you feed your infant so that their belly is nice and full.  This is important because we get the best data if your baby is sleeping and content, and a nice full belly helps with both of these.
• Once you are finished feeding your baby, we will remove their clothing, swaddle them in two blanks and wrap them in a papoose.  We need to do this because we can’t have any metal in the scanner. 
• We will also place neonatal ear muffs on your infant to protect their hearing.
• A nurse will monitor your baby’s heart rate and oxygen during the entire scan and we will also monitor via a video camera and sound system located in the scanner.

The scan will itself will take approximately 90 minutes, but it may be longer when you account for transport to and from the scanner.

At the follow-up visit, you will participate in your child’s developmental testing. You will also complete surveys about yourself and your baby. 

In the six-year follow-up visit, we will be obtaining questionnaire and assessment data from you and your child. You will be compensated $150 for your time and an additional $50 for completing interviews. We would like to collect biologic samples from your child. In addition to collecting saliva, we will compensate you $45 for stool samples and the Food Survey, $45 for blood sample and $10 for collected teeth.

Your child will participate in activities with you and the staff.

You will complete surveys and participate in activities with your child and interviews with the staff.

A magnetic resonance image (MRI) scan will be performed to take structural pictures of your child’s brain.

Your child will put on MRI-safe rocket pajamas to wear into the scanner room, wear ear plugs and headphones to protect their ears, and watch movies while the machine takes pictures of their brain. They will get to take a picture of their brain when the scan is over! A staff member will be with your child the entire time. Your child will be allowed to take breaks and communicate with staff during the MRI scan. The actual MRI scan will take approximately 60 minutes. If your child is unable to finish the scan, we will work with you to schedule another visit to complete it. We will compensate you $150 for your participation.

1. Play the white noise that your child will hear in the scanner during your child’s nap or bedtime. You can increase the volume of the sound as your child becomes more accustomed to it. See the audio file below

2. Watch the ear plug video and talk with your child about how we put in ear plugs to protect their ears from the loud sounds. Here is the video that describes how we do it:

In the nine/ten-year follow-up visit, we will be obtaining questionnaire and assessment data from you and your child. We would like to use this data for studies going on right now, as well as studies that are conducted in the future. 

As part of the research study, you will be asked to complete a self-administered interview about your child’s behavior and development, and a brief questionnaire about your health. 

Your child will undergo developmental assessments, as well as a special examination to take pictures of your child’s brain using a magnetic resonance image (MRI) scan. The developmental testing and MRI imaging will take approximately four hours to complete. After the completion of your nine/ten-year follow up, you will be compensated $200 for your participation, and your child will receive a small gift.

Your child’s developmental testing will be videotaped, as it is necessary for the tester to review the video after testing for scoring purposes. The tests may assist in recognizing areas of strength and challenges that your child may be facing. This part of the follow up should last two and a half hours.

Additionally, we would like to understand if your child’s development is related to services you or your family received while in the study. To do this, we will ask to access service records from early childhood support services, such as through the Missouri Department of Social Services.

You have already completed a questionnaire about your child’s development, your family, your home life, your health, and your child’s health. As stated above, in this follow-up visit, you will be asked to complete a self-administered interview about your child’s behavior and development, as well as a brief questionnaire about your health. Your involvement will last approximately two and a half hours.

We would also like to ask your child’s teacher to fill out a brief questionnaire. This questionnaire will ask questions about your child’s behavioral functioning in the classroom setting, and their overall development. The teacher’s responses to these questions will be coded to protect their confidentiality and your child’s confidentiality.

A magnetic resonance image (MRI) scan will be performed to take structural pictures of your child’s brain. Before the actual scan, you and your child will first undergo a practice MRI scan to become familiar with the scanning procedures. The practice MRI scan will last about 20-30 minutes. If your child is unable to complete the practice MRI scan, the research team may decide not to complete the full MRI scan. 

The MRI scan contains a table which your child will lie down on. Your child’s head and shoulder will be in a plastic head coil that will make it easier to lie still. The table is then moved into a large cylinder, and the MRI scanner uses a magnet to take pictures of the brain. The scanner makes loud noises, so we will provide your child with earplugs and headphones. Your child will be allowed to take breaks and communicate with staff during the MRI scan. The actual MRI scan will take approximately 60 minutes. If your child is unable to finish the scan, we will work with you to schedule another visit to complete it.

After completing both the practice and actual MRI scan, we will compensate you $100 for your participation.

You can watch this video to learn more about what to expect at the MRI scan.
