There are a number of internationally recognised questionnaires and rating scales, as well as some physical and mental health questionnaires, which you’ll need to complete before we can book you in for an ADHD assessment. These questionnaires are a crucial part of the process, and allow your clinician to perform a thorough assessment of your symptoms and the impact they have on your life. 

We appreciate that this is a bit of paperwork that requires a bit of work up front. However, these provide your assessor with the evidence they need prepare and to make an accurate diagnosis. It saves a lot of work for you further down the line.

• Adult ADHD Self Report Scale (ASRS) is our screening tool used on our referral form and on the website to ensure patients meet the criteria for a further assessment of ADHD. 

• Weiss Functioning Impairment Rating Scale (WFIRS) Self Report to evaluate functional impairment in domains typically affected with ADHD 

• Patient Health Questionnaire 9 (PHQ-9) to screen for depression 

• General Anxiety Disorder 7 (GAD-7) to screen for anxiety 

• Childhood Informant Questionnaire providing collateral information of symptoms in childhood 

• Adult Informant Questionnaire providing collateral information of current symptoms 

• DIVA-5 Diagnostic Interview for ADHD in adults 

• Physical Health Questionnaire to screen for physical health co-morbidities 

The Childhood and Adult informant questionnaires need to completed by one or two people who know you well – they provide insights into your characteristics as a child and an adult. This additional perspective significantly strengthens the evidence used in your clinician’s evaluation. 

Guidance on ADHD assessments, states that there should be 'collateral' information to support the evidence needed to make a diagnosis (in addition to what the patient themselves report).

In order to be diagnosed there must be clear evidence of symptoms and impairments going back to childhood – under the age of 7. A clinician cannot make a diagnosis without clear evidence of this.   
 
The informants don’t need to be family members, they can be friends, colleagues, carers or anyone who knows you well. The childhood informant should be someone who knew you when you were around 7 years old. 
 
We appreciate that some people really might not have anyone available who can provide this supporting evidence. Sometimes, people can provide old school reports as evidence of their symptoms in childhood. If you have school reports you would like to provide, please upload them via our client portal. 
 
If you cannot get someone to complete this scale, there is another form that you can complete as a self-assessment about yourself as a child (Wender Utah Rating Scale), but this is only a very last resort and the evidence is less strong towards making a diagnosis. This means that we may not be able to provide a diagnosis if the evidence from other sources is not strong enough to support it. 

This questionnaire helps you and your assessor understand your symptoms from the perspective of someone who knows you well as an adult. It plays a crucial role in the assessment process, and without it, we may be unable to confirm or rule out an ADHD diagnosis.  

Your informant doesn’t need to be a family member. They could be a friend, colleague, carer, or anyone who knows you well.   

If there is no one who can complete the adult informant form, we will still assess you, but please be aware that we will not be able to provide a diagnosis if there is not enough evidence from other sources to support it.
