The number of kids diagnosed with Autism Spectrum Disorder (ASD) has skyrocketed over the past 20 years--from 1 in 10,000 to 1 in 150. Unfortunately, many therapists still don't fully understand the diagnosis and aren't prepared to help families deal with the often overwhelming challenges and choices they must face in caring for their children. In this workshop, we'll define ASD and review current research and controversies about the diagnosis. We'll consider the dizzying array of treatment options available for ASD and discuss how therapists might best help families negotiate these complex choices while giving them the emotional support they need. We'll conclude with an in-depth look at the Relationship Development Intervention, a promising new approach that empowers parents to help their children remediate the five core deficits unique to ASD.
