Undertaking Your Autism Assessment Online
Background
When assessing whether a child or adult meets the diagnostic criteria for autism spectrum disorder the clinical team will analyse a wide range of evidence across the age range and consider whether the DSM5 criteria are met (see further article on diagnosis). At Veritas, we gather background information and information from other informants as well as undertaking the gold standard ADOS-2, ADI-r or RAADS-R assessment tools as part of the process. An autism diagnosis must be made by a clinical team who have reviewed a wide range of evidence, a diagnosis is never made based on a single assessment tool.
Utilising Videoconferencing
We always undertake parts of our autism assessment online; this is much more convenient for families and is much more environmentally friendly. Every autism assessment has a diagnostic history component, this means that an assessment tool is used to consider characteristics of autism that were present in childhood. We will either use the ADI-r or RAADS-R interview tools to gather this information, and this interview will be completed online via videoconferencing facilities.
This means that individuals or families can log on from home to complete the session and if required, parents/individuals can log on from different households.
When undertaking the developmental history component of the autism assessment it is often useful to have access to photographs and items such as school reports or developmental milestone records to help with remembering behaviours in childhood; undertaking the assessment at home makes this much more convenient for families, who also benefit from not having to travel to the appointment.
Is an Online Observation of Autism Symptoms Accurate?
The other major component of an autism assessment is the direct observation. In many cases this can also be undertaken online, in the form of an online ADOS-2 assessment.
The ADOS-2 is a gold standard assessment tool; it is a semi structured observation that allows clinicians to observe and code characteristics of autism. The ADOS-2 has five modules, the module that is used is chosen by the clinician, based on the age of the individual being assessed and their level of language.
The toddler module, along with modules 1, 2 and 3 involve play based activities, it is not possible to fully deliver these online. The module 4 however, does not have play-based activities and the activities that are in the module 4 can easily be adopted for online administration.
When administering an ADOS-2, the clinician will be administering the activities and questions whilst observing the behaviours and responses of the individual being assessed. They will be looking for things such as facial expressions and use of gesture and the overall quality and reciprocity of the interaction. These things can be observed on camera if delivering an assessment online.
The delivery of online autism assessment became more popular during the COVID 19 pandemic, and many clinicians are now highly experienced in delivering assessments in this way. Some individuals and families have been understandably concerned about the validity of being assessed in this way. There have been a few small studies published previously which demonstrated that undertaking a ADOS-2 module 4 online was a valid option, now there is also research which supports this.
A more robust piece of research was published early in 2023 by Cambridge University press on behalf of the Royal College of Psychiatrists. The research compared the outcome of 163 online ADOS-2 assessments with 198 in-person ADOS-2 assessments. The researchers found that there was no difference in the total scores between those who had undertaken the assessment online compared with those who had the assessment face to face. There was also no significant difference in the communication domain scores between the two groups. In both the online and the face-to-face group, the individuals who received an autism diagnosis had much higher scores than those that did not receive a diagnosis. The research also found that there was no difference between male and female scores when comparing the two, showing that the online ADOS-2 is equally useful for assessing female presentations.
Who is the ADOS-2 Module 4 Suitable For?
The ADOS 2 Module 4 is used for verbally fluent adolescents and adults, with the Module 3 being used for verbally fluent children and adolescents. The Module 3 involves some some play activities, whereas the Module 4 does not.
At Veritas we tend to choose to use the Module 4 for verbally fluent adolescents and preadolescents who (if typically developing) would have grown out of enjoying playing pretend games, and are able to cope with additional questions. We therefore typically would use a Module 4 from around the age of 12 upwards, but often children as young as 10 are able to cope with this module.
Choosing Whether to Undertake Your Assessment Online or in Person
Now that we can be sure that both methods of delivering the ADOS-2 Module 4 are valid, our clients can decide which is the best option for them.
For many, an autism assessment can be very stressful, and this can be compounded by travelling to and visiting a clinic; therefore, an online assessment may be a better option for those who find new people and places significantly challenging. Online assessments also require less time commitment, due to there being no travel needed.
We at Veritas find that things that bring the individual comfort at home can also help to decrease anxiety, we have had many a dog and cat join in our online sessions!
Individuals will have personal preferences to consider when choosing whether to have an assessment online or face to face, and we respect our client’s choices.
We have a younger child, but could not attend a face-to-face session, what can we do?
In exceptional circumstances, we can use the Brief Observation of the Symptoms of Autism (BOSA) protocol, as an alternative to the ADOS-2. The BOSA can be delivered online for all ages. The BOSA protocol sets out interactive tasks that are undertaken between a parent and child at home whilst a clinician observes via a video link. The tasks are straight forward, and parents can access a training video beforehand and will be coached by the clinician during the session.
If you have difficult circumstances that are acting as a barrier to accessing an assessment, we will be happy to talk through your options with you.
