Enroll in a Study.

Advances in understanding autism and related disorders are only possible as a direct result of the participation of individuals and families.

However, finding study participants is one of the greatest challenges researchers face. Simply put – scientists cannot make real progress without your help. We need you!

Studies Currently Enrolling:

Environmental Influences on Child Health Outcomes (ECHO) Study

ECHO is a nationwide research program whose mission is to improve the health of children for generations to come. The goal is to learn how the environment affects children’s health and development, and how it interacts with genetic information. The environment includes things that children may experience throughout their lives and even before they are born, like the air they breathe, foods they eat, interactions with other people, and the neighborhoods where they live. Children ages 5-11 and a biological parent are invited to participate. The study involves one visit, with in-person and remote components, in which the child will complete a cognitive assessment and body measurements, and both the child and parent will complete questionnaires and provide bio-samples (saliva, blood, hair, and toenails).

Epilepsy Study

The goal of this study is to understand the brain responses of children with Autism and how they differ from those with Epilepsy. Participants are asked to:

1. Visit the Roberts Center for Pediatric Research. Your child will complete a number of tests to measure their motor and problem solving skills. Parents will be asked to complete a few questionnaires about their child's development.

2. Visit the Children's Hospital of Philadelphia. Your child will complete non- invasive brain imaging.

Participants will be compensated for their time in the study and may receive verbal feedback from the study psychologist summarizing their cognitive testing.

Infant Brain Imaging Study (IBIS)

We are currently enrolling infants aged 6 months in the Infant Brain Imagine Study (IBIS). This study seeks to understand the key differences and similarities in brain development between infants whose siblings do and do not autism. Participants will be asked to make 3 visits to CHOP over time to complete cognitive and behavioral testing and a non-invasive MRI. Participants will be compensated for their time and receive a written feedback report.

Neural Correlates of Simulated Driving

We want to measure brain response to driving tasks, like turning and braking, using a simulator and brain scans. We’re trying to understand any differences in participants who are typically developing, have an Autism Spectrum Disorder diagnosis, or have undergone neurosurgery. We hope to identify safety concerns as well as inform treatment to help with the driving process. We are looking for people 12-17 years old with autism and without autism. We will complete a questionnaire and medical/research record review to see if you're eligible for our study. If eligible, you will be asked to come to CHOP for two 4-6 hour visits. You will complete non-invasive brain imaging and driving simulation during one visit and cognitive, behavioral, sensory and motor testing during the other visit. You will receive compensation and free parking for your participation.

Speech & Language Processing in Minimally & Non-Verbal Children

The goal of this study is to understand how children with little or no speech understand sounds and words. This study is enrolling boys and girls ages 8-12 who have ASD and are minimally verbal or nonverbal OR have a Developmental or Intellectual Disability (DD/ID).  What we learn from this study may help other people who have little or no speech. You will also receive a short report summarizing your child’s language and problem-solving skills.

Toddler Brain Development Study

We are conducting a study to understand brain development in infants that are typically developing compared with young children who have an Autism Spectrum Disorder (ASD) Diagnosis. We will use new non-invasive brain imaging methods developed for infants and young children. We are asking typically developing infants and children between the ages of 2 to 5 years to participate. By conducting brain imaging scans of brain activity in infants, toddlers, and pre-school children we will see how brain processes change across development. We will eventually use this information to better understand brain processes in children with neurodevelopmental disorders such as autism. We will pay you for your time in the study. In addition, your child will receive a small gift.

TUNE IN (Training to Understand Emotions and Interactions)

The goal of this research study is to test the effectiveness of a new treatment program to improve social functioning in adults with autism spectrum disorder. Adults age 18 years or older with autism spectrum disorder who can attend weekly sessions for this 6-month program are eligible. You will be asked to participate in interviews and fill out questionnaires to assess autism symptoms, social understanding, and social skills. You may also (50% chance) be asked to attend weekly meetings including individual meetings with a research staff member, group meetings with staff and other study participants, and finally weekly volunteer work sessions. The weekly participation will last approximately 6 months and will occur online via teleconferencing software. It is possible that participation in this study may improve your comfort and skill in many types of social situations. Compensation will be provided.

Vocal Biomarkers

The goal of this research study is to identify unique characteristics in the way kids and teens with Autism Spectrum Disorder (ASD) speak in comparison to typically developing peers. We are looking to partner with children and adolescents ages 6-17 with a confirmed diagnosis of autism spectrum disorder and typically developing children and adolescents. In response to the COVID-19 pandemic, all study activities may be completed from home. Participants will be asked to complete questionnaires, as well as weekly language-based activities 7 times. You will receive compensation for your participation. Upon request, you will receive a clinical report detailing assessment results.

If you are interested in participating in the study or want to learn more about it please contact Maggie Rose Pelella at CARLanguageLab@chop.edu or call (267) 425-1157.

Social Coordination

How we communicate – our body language, tone, expression – says just as much as our words. This study compares how people with different backgrounds and medical conditions use language and non-verbal methods to interact. We are looking for children between the ages of 12 and 17 to participate along with their parents. Typically developing children as well as children who are diagnosed with ADHD, Anxiety Disorder, Autism, Bipolar Disorder, Depression, or Oppositional Defiant Disorder are invited to participate. You will complete one longer visit or a few shorter virtual visits, where you will meet with our clinicians and research team. During this visit you will play games and talk with our research staff. All participants will also receive a full psychological work-up, including behavioral testing for ADHD, anxiety, autism, and mood disorders. The study also includes a full psychological evaluation by a CHOP expert as well as IQ screening and clinical feedback and guidance, free of charge. Participants will be compensated for their time and travel.
