This multi-site consortium research study, entitled the HEALthy Brain and Child Development (HBCD) study, willprospectively examine human brain, cognitive, behavioral, social, and emotional development beginning prenatallythrough age 10 years. The study will determine the short- and long-term impacts of a variety of potentially harmfulas well as protective environmental factors. These include prenatal substance use, mental health, stress,sociodemographics, biological and genetic factors, and parent/child interaction. The overall goal of this study is tounderstand the neurodevelopmental trajectories of children growing up in diverse environments. A sample of~7,500 pregnant women will be recruited from 25 sites across the U.S. and they and their liveborn children will befollowed for 10 years.

If you agree for you and your child to participate, we will ask you to take part in completing visits from pregnancy through the first 10 years of your child’s life. These visits will take place both in-person and remotely. The length of visits will vary and may last between approximately one to nine hours per visit (which can be broken up into multiple visits). Over the first four years of the study, all study visits will require about 33-37 hours total. This will include interviews, questionnaires and other tests about yourself and your child. We will ask you and your child to wear small devices for a few days to measure heart rate and or movement. We will ask you and your child to provide some biological samples. Because this study is looking at how a child’s brain develops in the first years of life, we will ask that you allow your child to have brain scans and other measures of how your child’s brain is developing. This study is being offered in both State College, PA at the University Park campus and in Hershey, PA at the College of Medicine campus. You may choose to complete this study at either site.

This study will examine various factors within the home of children adopted from the child welfare system between the ages of 4 and 10 that may impact their development. The first visit will occur remotely via Penn State Health Microsoft Teams; the second visit is optional and will occur within 4 weeks of the first visit at the Transforming Lives of Children Center in Harrisburg, PA; and the third visit will occur one year after the first visit, when research staff will travel to participants' homes. This research will help understand the factors that impact the development of children adopted from the child welfare system and how we may better serve these children and their families.

The child and parent will be asked to complete interviews, questionnaires and various tasks. Parents may also be asked to complete questionnaires online.Participation will last for one year and include the following:-One visit occurring remotely via PSH Microsoft Teams-One visit at the Transforming the Lives of Children Center in Harrisburg, PA, four weeks after Zoom visit (optional)-Final visit at home will occur one year after the first Zoom visit

The aim of this study is to better understand emotion regulation in infants by measuring brain, behavior, and mother-infant relational mechanisms. We plan to collect simultaneous brain activation in mothers and infants while they engage in a face-to-face interaction. We will then test associations between individual brain activation, mother-infant brain synchrony, and infant emotion regulation behaviors.

Participants complete questionnaires online, then come in for 1 in-person visit. Mother and baby complete a play and a neutral task while fNIRS is collected from them simultaneously.

The purpose of this study is to identify changes in salivary micro ribosomal nucleic acid (miRNA) expression that are predictive of symptom duration and severity following mild traumatic brain injury (mTBI) in children. The primary endpoints of this study are as follows:1)Characterization of brain-related miRNA in the saliva of 250 children with mTBI and 200 age- and gender-matched controls between the ages of five and twenty-three years.2)Identification of a set of salivary miRNAs that is predictive of duration and severity of mTBI symptoms.

Saliva collection and surveys at baseline, 7 days, and 30 Days

The purpose of this study is to gather information about what family mealtimes look like for families with children between the ages of 3 and 8. Families will be asked to video record their family mealtime, in addition to answer some questions and to complete some questionnaires, some about body image and dieting.

On one occasion, your family's mealtime will be recorded via Zoom. You and your family will be asked some questions and to complete some questionnaires online.
