The Conners Comprehensive Behaviour Rating Scale (CBRS), is a tool used to gain a better understanding of academic, behavioural and social issues that are seen in young children between ages 6 to 18 years old. It is frequently used to assist in the diagnosis of attention deficit hyperactivity disorder (ADHD). It helps the doctor or assessor to better understand the symptoms and their severity. If the child presents symptoms of ADHD, then usually the parents will have to undergo a CBRS test as well, after which they will compare and analyse the results, which helps the doctor create a more accurate diagnosis.
