Assessment of Behaviours that Challenge
When trying to assess the causes of behaviours that challenge in people who have Cri du Chat syndrome, it is important to remember that behaviours that challenge have not always occurred and does not occur all of the time for any child or adult (it just feels like that sometimes!). This means that the behaviours that challenge are likely to be related to either internal or external factors that have changed over a long period of time or change on a more short-term basis.
Successful assessment of the causes of behaviours that challenge rests on finding out more about the events that occur before and after the behaviour.
There are a number of assessments that can be conducted to help understand the factors that may be causing behaviours that challenge. Some of the assessments can be carried out by anybody who has a good knowledge of the person showing behaviours that challenge. However, some assessments require more expertise and families are encouraged to seek assistance from professionals.
When conducting an assessment, it is essential to keep good written records as these records will be the key to understanding behaviour. A professional, such as a clinical psychologist or behavioural nurse, will be able to help you interpret these records.

ABC Charts
The ‘ABC’ stands for antecedent, behaviour, consequence. The person who completes these charts writes down exactly what was going on before, during and after the behaviours that challenge. It is really important that the record keeper gives a really good and detailed description when completing ABC charts.

Unstructured natural observations
In an unstructured natural observation the person with Cri du Chat syndrome is observed in a number of naturally occurring situations and environments. For example, playing with an adult, playing by themselves when an adult is present in the room or completing a unpreferred activity. The person observing keeps a record of how many times the behaviours that challenge occurred and for how long, in each situation. If behaviour goes up and down in different situations this gives a clue to the function of the behaviour. It is very important to do several good quality observations before making any conclusions about the behaviour. Getting support from a behavioural specialist such as a clinical psychologist or behavioural nurse is advised when interpreting the records collected from these assessments.
Specialist Assessments
There are a number of assessments that we would recommend are conducted with the help of a professional as there are a number of risks associated with these assessments that need to be managed carefully. The assessments are experimental analogues and structured descriptive assessments. These assessments are the gold standard in behaviour assessment and involve systematically changing what is happening around the person to see how this impacts on behaviour.
Questionnaire Measures
Professionals often ask carers to complete questionnaire measures about behaviour and two good questionnaires are the Motivational Assessment Scale (MAS) and the Questions about Behavioural Function Scale (QABS).
