The purpose of this research study is to evaluate Parent Child Interaction Therapy (PCIT) delivered via tele-health for young children with a developmental diagnosis (ex. suspected or diagnosed autism, ADHD, global developmental delay, etc.) 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, at no cost. 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. Families will be compensated for their time.

Candidates for this study may or may not report disturbances in odor perception as their primary reason for seeking treatment at MUSC. This study is designed to collect long term, observational data from patients who are being treated with routine clinical care in health clinics at MUSC. Data from clinical questionnaires will be de-identified and stored in a database.
