The DBC 2 is a revised version of the DBC, an instrument that has been in wide international use for over 20 years, and it can be completed by a parent, teacher, or other adult. Unlike other rating scales of emotional and behavioural problems, the DBC 2 is focused on difficulties most likely to be a problem in the intellectually and developmentally disabled population. Scores are based on this population, allowing for a more accurate depiction of behaviour.
The DBC 2 consists of three forms: Parent, Teacher, and Adult. The DBC 2 yields a Total Score and five subscale scores which can be used for clinical, educational, or research purposes. T‐scores can be interpreted based on the range of concern in which they fall. Additionally, the Total T‐score can be compared with a clinical cutoff.
