Adult ADHD assessment in Glasgow
Adult ADHD assessments in Glasgow and online, carried out by HCPC-registered clinical psychologists. We use the DIVA structured interview alongside a full developmental history, and you receive a written report with recommendations you can act on.
What the assessment includes
Our ADHD assessment is a thorough, evidence-based evaluation designed to give you diagnostic clarity and practical support. It includes:
- Developmental history: a detailed exploration of your early development, education, and life experiences to identify longstanding patterns consistent with ADHD.
- Clinical interview: a structured conversation covering current symptoms, daily functioning, relationships, work or study, and mental health history.
- DIVA (Diagnostic Interview for ADHD in Adults): a structured clinical interview that systematically examines ADHD symptoms across childhood and adulthood, using concrete examples from your daily life. The DIVA is recognised internationally as a best-practice diagnostic tool for adult ADHD.
- Collateral information: where possible, we gather supporting information from someone who knew you as a child (such as a parent or sibling) to strengthen the developmental picture.
- Written report: a detailed document outlining the assessment findings, diagnostic conclusions, and personalised recommendations for support, adjustments, and next steps.
Who should consider an ADHD assessment
Many adults live with undiagnosed ADHD for years, often developing their own strategies to cope while feeling that things are harder for them than they seem to be for others. You may benefit from an ADHD assessment if you recognise a persistent pattern of:
- Difficulty concentrating or sustaining attention, especially on tasks that are not immediately stimulating
- Chronic disorganisation, frequently losing things, or struggling to keep on top of responsibilities
- Impulsivity in decision-making, spending, or conversations
- Restlessness or an internal sense of being constantly "on the go"
- Difficulty managing time, meeting deadlines, or estimating how long tasks will take
- Emotional dysregulation, including quick frustration, mood swings, or difficulty managing strong feelings
It is increasingly recognised that many adults, particularly women and those who performed well academically, can reach adulthood without a diagnosis. The NHS estimates that ADHD affects around 3 to 4% of adults in the UK. Seeking an assessment later in life is both common and entirely valid. Understanding whether ADHD is part of your picture can be a turning point in making sense of your experiences.
ADHD often coexists with other difficulties such as anxiety, depression, low self-esteem, and burnout. If you are also experiencing emotional difficulties alongside attention and concentration problems, our team can help you understand how these connect and what kind of support would be most useful.
What happens, step by step
We aim to make the assessment as straightforward and supportive as possible. Here is what to expect:
- Get in touch: tell us what is prompting the assessment. We will confirm it is the right next step and offer dates.
- Assessment sessions: one or two sessions, in person or by video, covering the interview, developmental history and the DIVA.
- Report writing: your psychologist analyses everything gathered and prepares your written report, usually within three to four weeks of the final session.
- Feedback session: a dedicated session to discuss the findings, answer your questions, and talk through the recommendations in your report.
Fees
The fee is £900 and covers everything above: the sessions, scoring, your written report and the feedback session. There are no extras.
If you need the report by a particular date, tell us and we will do our best.
If you are also considering an autism assessment, we offer a combined ADHD and autism assessment for £1,850. This is more efficient and cost-effective than two separate assessments, with integrated findings in a single report.
