ADHD Assessment


The assessment for ADHD is rigorous and involves a combination of qualitative and quantitative questionaires, objective measures, and a clinical interview.

The clinical interview component usually takes 3-4hrs, and the findings are presented in a report. Medication titration costs are incorporated in the assessment fee.

Medication Review/titration


Medication reviews are 30 minutes long. Titrations are charged at a flat fee.

For children who are stable on medication, reviews are scheduled 6 monthly. For adults reviews are conducted yearly.

Gavin will write a consultation letter to your GP following the review.

QB Check


A QB check is a computerised continuous performance test. The test can be done at home on a computer.

The test takes 15 or 20 minutes depending on age. The QB check is objective and unbiased and helps to diagnose ADHD and evaluates treatment. Gavin will summarise the QB check findings in a brief report.

What is involved in an assessment for ADHD? 

  1. A brief virtual appointment will be arranged to discuss the patients’ difficulties and to enable patients to see if they think Gavin is the right ‘fit’ for the assessment/treatment. This is important because the assessment process is very personal, therefore it is crucial patients feel safe and supported.  
  2. Packs: 
    For children and adolescents: A ‘parent pack’ will be sent electronically. This enables us to gather as much background as possible about the patient and includes the relevant history, the difficulties and goals. Another pack is usually sent to the Childs teacher (or other informant) as this allows us to ascertain additional objective viewpoints. In both packs there are ADHD specific rating scales and free text boxes to elaborate on impairments. I will need to have both pre assessment packs returned before I can book the clinical interview. 
    For adults: Essentially the same as above, however, packs will be sent to the adult patient and a nominated informant who is ideally someone who has known the patient since childhood. The adult pack includes age and sex appropriate screening forms and rating scales.  
  1. QB Check: A QB Check is an unbiased continuous performance test that can be undertaken remotely i.e., at home on a PC or laptop in a quiet setting. The QB Check is age normed and takes 15 or 20 minutes depending on the patient’s age.  
  2. Developmental History: A recognised semi-structured interview is used to assess ADHD symptoms in more depth. This appointment can take place in person or virtually depending on your location and circumstances. This assessment can take 1-2hrs.  
  3. Feedback session and report: I will use the information gathered in the pre-assessment packs and the developmental history to arrive at a diagnostic outcome. Sometimes when the outcome is clear this feedback can be given on the same day, however, it is often an emotional experience receiving a diagnosis of ADHD for a child and adult and I am careful to give time to validate these feelings and to talk about the next steps depending on the goals. I aim to deliver the assessment report within a week.  

What is involved in a medication review?

Medication reviews are scheduled for 30 minutes. The main points of the review are to ascertain how well the treatment is working, to discuss side effects and to decide whether the treatment is optimised. Following the review, a letter will be sent to the patients GP to update them on the progress of the treatment.
