The purpose of this research study is to evaluate Parent Child Interaction Therapy (PCIT) delivered via tele-health for young children with autism spectrum disorder (ASD) and disruptive behavior problems. Participants will go through a screening to determine eligibility. Once screening is complete, participants will complete a pre-therapy assessment in clinic, followed by 10 telehealth sessions one time per week. Participants will then be asked to complete an in-person post-therapy assessment and follow-up questionnaires will be re-administered 3 months following the completion of therapy.
No laboratory based diagnostic test for Autism Spectrum Disorder (ASD) currently exists. The goal of this study is to develop blood test for ASD using metabolic profiling, and to then evaluate this test using a large sample of three to six year old children with and without ASD. Having a reliable blood test for ASD will allow for rapid identification of young children who may have ASD, and will allow these children to get expedited access to treatments.
