Exploring an ADHD assessment is an important moment in your life.

Whilst ADHD is a neurodevelopmental condition, people come to us to explore an ADHD assessment at any stage in life. Many young and adult people now recognise themselves as being neurodivergent and find the diagnosis useful in identifying coping strategies.

Having your ADHD assessment

We offer comprehensive ADHD assessments that are holistic, and person centred. Our approach is prompt and flexible.

The clinician will explain and go through each step of the assessment with you and your family. At the end of the assessment process the clinician will also explain why we gathered the information we did and what purpose each information had in the outcome.

We will explore different aspect of your (patient/client) life and your family members concerns, before arriving at a diagnostic conclusion. Ultimately, our aim is to find meaningful ways of understanding your experiences, difficulties, preference and traits. This may mean using an ADHD framework and/or other psychological formulations.

We will use gold standard’ ADHD assessment tools based on the National Institute for Health and Care Excellence (NICE) Guidance’s recommendations. This includes:

  • A full clinical and psychosocial assessment of the person; this should include discussion and symptoms in the different domains and settings of the person’s everyday life.

  • A full developmental and psychiatric history.

  • Observer reports and assessment of the person’s mental health state.

  • Conners’ rating scales and Strengths and Difficulties Questionnaire.

Our approach ensures that our findings are reliable, accurate and valid. This means that your ADHD assessment outcome will be recognised by the NHS and internationally.

What to expect of an ADHD assessment?

Step 1: Initial ADHD screening

An initial meeting to understand your current concerns, (be it for you or in a child’s case, concerns expressed by carers), life circumstances, and early life experiences. Following the initial screening, we will share recommendations and decide with the best way forward.

Step 2: ADHD Assessment:

Clinical Interview

An initial meeting in person to understand your current concerns, life circumstances and early life experiences. Afterwards, we will share recommendations and decide with the best way forward.

Observational Assessment

We will carry out a standardised questionnaire called Strengths and Difficulties questionnaire and fill out the Conners’ assessment tool appropriate for each age. This gives us an opportunity to understand social skills and difficulties presented in a clinical setting as well as in the person’s day to day life.

Informant interview:

If possible, this involves speaking to someone that knows you or the person well. We will include this information in the final report. We also include review of other agencies involved with the person being assessed (other healthcare professionals such as Psychologists, Psychiatrists and physicians).

*Sometimes, we may need additional assessment meetings (such as a school or work observation) to gather more information and better understand the patient/client experiences and needs, in which case, we will discuss this with you or the person responsible.

What to expect at your feedback and outcome:

We will share with you the diagnostic outcome. This involves explaining the possible diagnosis of ADHD and how the information gathered helps us to reach our conclusion.

There are three possible outcomes:

You (patient/client) meet the diagnostic criteria

We will explain why we think an ADHD framework makes sense in understanding your experiences and presentation. We will discuss your strengths and needs. Where appropriate, we will explore therapy options for your difficulties.

You (patient/client) do not meet the diagnostic criteria

We will consider differential diagnoses or alternative ways of understanding your difficulties. Additionally, we will discuss the kind of help that you would benefit from.

We are not able to conclude (for now)

Sometimes people may have experienced complex trauma or mental health difficulties. The effects on their well-being and functioning may need to be addressed before considering a neurodevelopmental diagnosis.

In this case, we will discuss the kind of help that you would benefit from. Subsequently, we may continue working with you or signpost you to our colleagues in our professional network.

Ultimately, our aim is to find the best way to understand you (patient/client) and your needs and identify the most helpful way forward for interventions and support.
