Outcome Measures
Primary Outcomes (1)
The Nisonger Child Behavior Rating Form- Typical Intelligence Quotient (NCBRF-TIQ) Conduct Problem Subscale Score
The Nisonger Child Behavior Rating Form (NCBRF) is an instrument designed to assess the behavior of children with intellectual or developmental disabilities. The NCBRF-TIQ is a 66-item behavior rating form designed to assess the behavior of children and adolescents with typical development. The NCBRF is made up of three sections: I, Where raters can identify unusual circumstances that may have affected the youth's behavior; II, where positive behaviors are rated, and III, a listing of problem behaviors. There are separate Teacher and Parent versions of the form, and the NCBRF takes about 15 minutes to complete. The NCBRF is designed to be used with children and adolescents ages 3 to 16 years. The lowest score is a "0" and the highest score is "198". A higher score of the Conduct Problem Subscale score means a worse outcome. A change or negative score means improvement. Data represent the change from baseline (Visit 1) and 11 time points (Visit 2 to Visit 12).
