RUBI: Study Objectives and Design • Efficacy Study – Parent Training vs Parent Education* – Children (3-7 yrs) with ASD & DBP
• 24 Week Trial – At Wk 24, a blinded independent evaluator (IE) classified subject as + or - response
• Follow-up:Wk 36 & 48 (not discussed here) *active comparator www.mghcme.org
Participants • • • •
3-0 to 6-11 years N=180 DSM-IV Diagnosis of ASD > 15 on the parent-rated Aberrant Behavior Checklist Irritability (ABC-I) subscale • Stable medication/treatment plan
www.mghcme.org
Program Structure Parent Training • Week 1-16 - 11 Core Sessions
- 2 Home Visits - Up to 2 Optional Sessions
Parent Education • Week 1-24 - 12 Core Sessions - 1 Home Visit
• toileting, feeding, sleep, time out
Both treatments: 1:1 with parent, using the same format
www.mghcme.org
Primary & Key Secondary Outcome Measures • Parent-reported outcomes – Aberrant Behavior Checklist-Irritability subscale – Vineland
• Blinded Independent Evaluator – Parent Target Problems via parent interview – Improvement item of the Clinician Global Impression • Much/Very Much Improved = + Response

Conclusion • Largest RCT of a behavioral intervention for children with ASD. • Structured, relatively brief PT program was superior to PEP for disruptive behavior and daily living skills
www.mghcme.org
Future Directions • Dissemination – Getting the word out: not enough
• Implementation – Reach: access in clinics & schools
