| Conners Comprehensive Behaviour Rating Scale | |
| Purpose: | diagnose ADHD |
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 analyze the results, which helps the doctor create a more accurate diagnosis.
__TOC__
The CBRS was created to evaluate possible behavioural markers in children from ages to 6-18 comprehensively. These include:[1]
The CBRS has about 18 to 90 questions about the incidence of ADHD-related behaviours shown by the child. These questions are supplied by the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The rating is completed by the child's parents upon initial visit to the psychologist. Possible ADHD symptoms of the child can be determined along with the significance of each. This is done by asking questions about the child's home life, giving psychologists a better understanding of the child's normal behavioural patterns and habits. An analysis of the answers to the questions will help psychologists make a more accurate diagnosis of ADHD.
There are two versions of the CBRS, the short and the long version. They are both used for different purposes by behavioural experts. The length of the CBRS will be based on the individual child and how in depth the proposed analysis is.
There are three Conner's CBRS forms, each form contains different questions for the specific person filling the form out. The psychologists combine these answers to utilise for their analysis:[2]
These forms create a comprehensive list of the child's behaviours through the emotional, behavioural and academic screening questions asked.[3] The questions are multiple choice, examples of the topics of these questions relate to content scales; emotional distress, aggressive behaviours, academic difficulties, hyperactivity/impulsivity, separation fears, violence potential and physical symptoms.[4]
The short version of the CBRS is called the Conners Clinical Index (Conners CI), and can be finished in as little time as five minutes. It will consist of 25 questions with the possibility to vary depending on the child. The longer versions can take up to an hour and a half to complete.
The CBRS is a tool that has been widely developed and used in Western countries, however there are a lack of measures and applications of these types of tools in Asian countries, specifically Vietnam. Recently these standards and measures of the CBRS have been progressively improved and developed in Vietnam and other developing countries. The introduction of the CBRS has been seen to increase the early identification and intervention of problems in Vietnamese children, leading to the mitigation of symptoms that are related to social, emotional and behavioural difficulties. These problems have been seen to influence their personal development, relationships with family, academic achievement and possibility of future psychological disorders.
The application of the CBRS will vary between different countries due to cultural differences and norms. These simple characteristic dissimilarities can affect many areas of psychology including the diagnosis made, perception of behaviour, likelihood of seeking treatment and stigma of mental health services. In Vietnam the culture prioritises interdependence within families, friends and communities, which is seen to be more important than their individual needs. This means the Vietnamese depend heavily on social supports when dealing with mental health issues.
The results are calculated by the psychologist who totals all the areas of the assessments completed by the child, parent and some cases teacher. These scores are standardised by comparing them to the results of children within the same age group. T-scores are the mode of calculation used to analyse children's behavioural systems and their severity in contrast to other children. T-scores can also be converted into percentile scores. These scores are displayed in visual format including graphs and tables to make it easier to make more accurate judgements.
When the T-scores are less than 60, it means your child is in the normal range, however when the scores are above 60, there is possibility of behavioural issues. There are different categories:
The CBRS tool has limitations, according to the medical assessment publisher MHS Assessments, validity analyses are used to test the correctness of the CBRS Rating Scale. They also state that the mean accuracy rate of the CBRS is 78% from all three forms. There is also the fact that assessing a child's behaviour can be subjective. This subjectivity leads to psychologists being encouraged to pair the CBRS with other tests and scales. It is not a purely objective test. However, it can help better understand a child's behavioural, social and emotional stability. Further analysis is needed to help avoid a misdiagnosis, this can be done through pairing tests with attention span tests and an ADHD symptom checklist. The CBRS rating scale is not perfect, but when used correctly by a medical professional it will help people understand a child's behaviour in more depth.
