The Building Up Food Flexibility and Exposure Treatment (BUFFET) program helps autistic children 8-12 years old to be more flexible with trying new or non-preferred foods. BUFFET-Snack is a brief version of this treatment program. The goal of this study is to see if families can complete BUFFET-Snack and if they like it. BUFFET-Snack is a cognitive behavioral therapy. It will be a good fit for children who can communicate with full sentences and have some back-and-forth conversation skills.

The primary objective of this study is to measure camouflaging behaviors (i.e., behaviors that hide autistic symptoms) and social compensation (i.e., behaviors that explicitly support social interaction) in individuals with and without ASD using an online self-report questionnaire - the CAT-Q.

The Early Insights Research Study aims to understand brain development in infants and toddlers who may or may not develop intellectual or developmental delay. This study will use a non-invasive brain scanning technology called magnetoencephalography (MEG). We hope the information gained from this study may lead to possible treatment strategies for children who have intellectual or developmental delay.

This study aims to collect data from patients seen at CHOP, CHOP's 3550 Market St. primary care location, Penn, or from the surrounding communities. If you choose to participate, we will take an optional blood, saliva, and/or stool sample, have you complete computer testing that measures things like your reaction time and your memory, have you complete questionnaires, and we will interview you and your parent or legal guardian to ask questions about your life experiences and perceptions, and past and current mental health.

The purpose of this study is to test the safety of an investigational medicine called ML-004 and how it might affect communication, behavior, and other symptoms of autism spectrum disorder (ASD). This medication is investigational because it has not been approved by the FDA for the treatment of symptoms associated with autism.

You may qualify if you:

• Are 12 to 17 years old
• Have an autism diagnosis
• Have a designated care/study partner able to attend every visit and answer questions about the participant. This person does not need to be the participant's parent or guardian. This person should have significant contact with them and can support them for the duration of the study.
• Are able to swallow the study medication (tablet)

PEDSnet and DBPNet seek youth (13-24), parents, and clinicians/scientists for the Intellectual and Developmental Disabilities (IDD) Research Prioritization Study. The goal is to develop a prioritized list of research questions that will immediately impact patient health outcomes, focusing on children with IDD.
Participants will answer open-ended questions on Viva Engage, a Microsoft platform, to share their thoughts and opinions. The study is entirely online, and parents and youth will be compensated for their time. To participate or learn more, complete our eligibility screener.

The purpose of this study is to test an investigational medication in children and adolescents aged 5-17 years old with irritability associated with autism spectrum disorder (ASD). The name of the medication being tested in this study is pimavanserin. This medication is investigational because it has not been approved by the FDA for the treatment of irritability associated with autism. The main risks of this study are from the medication, which include nausea, dizziness, and sleepiness.

The mission of SPARK is to ignite research at an unprecedented scale to improve lives by advancing our understanding of autism. To join this national autism research cohort, individuals with a professional diagnosis of autism and their biological family members will be asked to share information about their medical and family history, as well as provide a DNA sample.
