    Adapting a Group Intervention for Emotion Dysregulation in Prader-Willi Syndrome
    Role Description: The goal of this study is to help teens with Prader-Willi Syndrome (PWS) and their families learn practical strategies for managing issues like irritability, meltdowns, and anxiety. The main objective of the study is to adapt current Regulating Together materials to create an outpatient group program for emotion dysregulation in Prader-Willi Syndrome (PWS) that will improve psychosocial outcomes for youth with PWS.

    Adapting a group intervention for emotion dysregulation in autism and intellectual disability
    Role Description: The goal of this study is to help children with autism and a co-occurring intellectual disability and their families learn practical strategies for managing issues like irritability, aggression, and other challenging behaviors. The main objective of this study is:To adapt current Regulating Together materials to create an outpatient group program for emotion dysregulation in autism and co-occurring intellectual disability (ASD + ID) that will improve psychosocial outcomes for youth with ASD + ID.
