Nisonger Child Behavior Rating Form (NCBRF)
The NCBRF  has six problem behaviour subscales: Conduct Problem, Insecure/Anxious, Hyperactive, Self-Injury/Stereotypic, Self-isolated/Ritualistic, and Overly Sensitive. Internal consistency of the problem behaviour scales was reported as good with Cronbach’s alpha >0.70 for all subscales in both parent and teacher versions . Test-retest reliability for the parent version was reported to be strong (ICC for total problem behaviour >0.80) but the teacher version fell short of the COSMIN criterion (ICC for total problem behaviour = 0.68); however, over a one year time interval, some change might well be expected. The agreement was low between parents and teachers on common items from the parent and teacher versions of the scale, indicating that inter-rater reliability was poor . Structural validity was also shown to be poor for problem behaviour with a 5-factor solution accounting for 47.5% of the variance . Finally, Lecavalier, Leone & Wiltz  provided fair evidence for divergent and convergent validity of the NCBRF though criterion validity was not assessed.
