Preparing for your ADHD assessment

A good assessment starts before the first appointment

Most people spend far longer deciding whether to have an ADHD assessment than they spend preparing for it. That is understandable — by the time an appointment is booked, the hard thinking feels done. But a little preparation genuinely changes what an assessment can achieve. Adult ADHD is diagnosed on history: what your difficulties look like now, what they have cost you over the years, and whether they reach back into childhood. The more of that story you can bring, the clearer the answer at the end of it.

This guide sets out what to gather, who can help, and what actually happens across the appointments — whether you are booking with Caledonian Psychiatry or preparing for an assessment elsewhere. If you are still weighing up whether to be assessed at all, the guide to private ADHD assessment in Scotland covers costs, waiting times and the process from the beginning.

What happens at the assessment

At Caledonian Psychiatry, an ADHD assessment runs over two 60-minute appointments by secure video, following NICE guidance and aligned with the AQAS (ADHD Quality Assured Service) standard. The first appointment concentrates on your current life: work, home, relationships, and where things keep going wrong despite your best efforts. The second reaches back into your developmental history and pulls the evidence together. There is no trick to any of it — it is a long, structured conversation with a psychiatrist who knows what to ask.

Nothing has to be decided on the spot, and there is no pass or fail. The task is simply to understand how your mind works and whether ADHD is the best explanation for the pattern — or whether something else fits better. Anxiety, low mood, sleep problems and life circumstances can all produce concentration difficulties, and a careful assessment weighs those alternatives rather than brushing past them.

What to gather beforehand

None of the following is required — people are assessed without any of it every week. But each item strengthens the evidence base your psychiatrist can draw on:

• School reports, if they still exist. Even a single line — “bright but easily distracted”, “must learn to concentrate”, “does not fulfil potential” — is contemporaneous evidence of childhood traits that no adult recollection can match. Parents and older relatives often know where these are kept.
• A copy of your GP summary record. Your GP practice can provide this on request, and many now offer it through their online services. It helps the psychiatrist see your medical history in the round, and it supports safe prescribing if medication becomes part of the plan.
• Any previous mental health reports. Earlier assessments, psychology reports or discharge letters — even where the conclusion was something other than ADHD — all add to the picture.
• A list of current medication, including doses, and anything you take over the counter.
• Concrete examples. A few real situations where your difficulties have cost you something — a missed deadline, a forgotten commitment, a relationship strain, a job that fell apart — are worth more than any amount of general description.

The screening questionnaires

Before booking, many people find it useful to complete the free screening questionnaires — the ASRS-5 for ADHD takes a couple of minutes. A high score does not mean you have ADHD, and a modest score does not rule it out; screening tools measure the visibility of symptoms, not their cause. But your answers give the assessment a useful starting point, and thinking through the questions often surfaces examples you would otherwise not have thought to mention.

The value of another perspective

ADHD assessment leans on developmental history, and someone who has known you a long time — a parent, an older sibling, a partner of many years — can often describe things you cannot see from the inside, or were too young to remember. If someone like that is willing to contribute, mention it when booking: they can join part of an appointment by video or provide their observations another way. Like everything else here, it is helpful rather than essential, and plenty of people are assessed entirely on their own account.

Come as you are, not as you cope

The most common mistake is not under-preparation but over-polish. Many adults who seek assessment have spent decades building systems to hide their difficulties — and then present the systems rather than the struggle. Describing your life at its most managed can talk an assessor out of a diagnosis that is genuinely there.

What matters is the cost of coping, not the appearance of it. If you hold everything together at work and collapse at home, say so. If your inbox is under control only because you check it forty times a day, that is the detail worth sharing. This pattern of effortful, expensive coping runs through ADHD in women in particular, and it is exactly what an experienced assessor wants to hear about, in your own unrehearsed words.

Thinking ahead: medication and your GP

You do not need to decide anything about treatment before an assessment, but it helps to know how the path runs. If ADHD is diagnosed and medication is recommended, most first-line options are controlled medicines, and safe prescribing means involving your GP before treatment starts — a short history from the practice and confirmation of your details. It is a routine step, not a barrier. Ongoing costs are set out openly on the medication costs page, and once treatment is stable many patients move to shared care, with the GP taking over routine prescribing.

Booking with Caledonian Psychiatry

You can refer yourself directly — no GP letter is needed to book. Assessments are delivered by secure video to adults anywhere in the UK, and the practice is regulated by Healthcare Improvement Scotland as an independent medical agency (reg. no. 03427). Every appointment is with a psychiatrist whose daily clinical work is adult ADHD, autism and mental health; the our approach page describes how assessments are run, and the published quality standards explain the benchmarks behind them.

The ADHD assessment costs £800 across the two 60-minute appointments, with the full schedule — including follow-up and prescription fees — on the fees page. You are given a clear answer at the end of the assessment rather than being left to wait for the post, and the written report — typically drafted on the day of the concluding appointment and checked carefully before it goes out — is sent within 7 to 10 working days to you and, with your consent, your GP.
