The Nisonger CBRF: a child behavior rating form for children with developmental disabilities.

Although the rate of behavior and emotional problems of children with mental retardation is considerably higher than the rate among typically developing children, there is a shortage of tools for assessing persons with mental retardation. The Child Behavior Rating Form (CBRF) was modified by altering instructions and adding new items describing behavior problems known to occur in children with mental retardation. The adapted scale was named the Nisonger CBRF. Three hundred sixty-nine children being assessed at a University Affiliated Program for MR/DD were rated on the CBRF by their parents and teachers. Independent factor analyses of parent and teacher ratings produced two Social Competence subscales and six Problem Behavior subscales. These results were largely consistent across rater types and similar to prior findings with the CBRF. Internal consistency was generally high, parent-teacher agreement was satisfactory, and subscales from the Nisonger CBRF correlated highly with analogous subscales from the Aberrant Behavior Checklist. The Nisonger CBRF appears to be a promising new tool for assessing behavioral and emotional problems in children with mental retardation; however, further psychometric work is warranted.
