Online, and properly thorough.
Why online is the right setting for adult ADHD assessment, what the evidence supports, and where we draw a clear line between a proper assessment and the high-volume services that have earned the field a reputation for cutting corners.
Is online assessment really the same thing?
Most people arrive at ADHD assessment after a long wait. By the time they finally book, they want to know they are doing the thorough, legitimate version. That is a reasonable instinct, and the question it produces is usually some form of this: should I be seen in person? Does online miss something important? Am I settling for a lesser service?
I think the question deserves a careful answer rather than reassurance. What follows is the clinical reasoning, the evidence, and the place where I would gently push back on the implicit assumption that in-person is automatically more rigorous. For adult ADHD specifically, online assessment is not a compromise. In several clinically important respects, it is the better setting. The thing that determines quality is not the delivery method. It is the depth of the assessment happening inside it.
Adult ADHD lives in history and pattern.
Assessing ADHD in a seven-year-old is a different task from assessing it in a 37-year-old. In children, direct observation carries real clinical weight. How a child sits, moves, attends across unstructured time, and responds to transitions tells you something about a picture that is still forming. That observational frame is genuinely useful at that age.
By adulthood, that frame has largely stopped working. Adults have spent two or three decades learning to sit still in important rooms. A clinic visit is one of the most socially structured environments an ordinary week contains. The person you observe in the consulting room is the most rehearsed, most compensated, most heavily masked version of the person you are trying to understand. It is the clinical equivalent of measuring someone's running speed by watching them walk into a meeting.
The real signal for adult ADHD lives somewhere quite specific.
- A detailed developmental history going back to childhood, cross-referenced where possible with school reports, early work patterns, and family accounts.
- Current functioning across work, home, relationships, and parenting, assessed not by an hour of presentation but by what your week, month, and year actually contain.
- Executive function in real situations. How you manage deadlines, track multiple streams, follow through on intention, regulate attention under load.
- Emotional regulation. How feelings arrive, how intensely they land, how quickly they shift, how long they linger afterwards.
- The careful differentiation from the conditions that overlap with ADHD: anxiety, depression, autism, trauma, and mood disorders.
- The internal experience of the person behind the capable presentation. The part of the picture that is almost never visible from a chair across a desk.
None of those live in how someone sits in an armchair. All of them come out in careful conversation. And conversation travels very well over a good video link.
The real difference is not online versus in-person. It is thorough versus superficial.

The published research, and what NICE actually requires.
NICE guidance on the diagnosis of ADHD does not specify delivery method. It requires a structured clinical interview, a developmental history, functional assessment, and consideration of co-occurring conditions. None of those are location-dependent.
The shift to online assessment accelerated during the pandemic and has been studied carefully since. The consistent finding, across multiple peer-reviewed studies of adult ADHD, is that telehealth assessment produces diagnostic accuracy equivalent to in-person assessment when conducted by appropriately trained clinicians using validated tools. Major NHS adult ADHD services now routinely operate online or hybrid. The Royal College of Psychiatrists has supported video-based psychiatric assessment as a legitimate pathway. This is not a workaround anymore. It is an established route.
Objective cognitive testing has moved with it. The QbCheck, which we include as standard, is a validated continuous performance test with normative data from thousands of adults and children and specific validation for remote administration. It contributes an independent behavioural measure that no amount of in-person observation can replicate, because it actually measures reaction time variability, micro-movement, and attentional lapses rather than inferring them. In that sense, a properly conducted online assessment often carries more objective data than the in-person gold standard of fifteen years ago.
The home setting gives clinical information the clinic cannot.
Several things happen when the assessment takes place in your own environment rather than a rented room.
Social performance pressure drops. People unmask more readily at home than they do in an unfamiliar room with an unknown professional. For an assessment in which masking is a major confounder, that is clinically useful, not a loss of fidelity. You are often closer to yourself by the end of a video call than you would be sitting in my office.
Collateral sources are easier to include. Partners, parents, or close friends can join for a portion of the assessment without the logistics of travel. In adult ADHD, external history is often gold, because the person being assessed has had decades to rewrite their own story into something more palatable. Making it easy for someone who knew you before you could mask to speak to the clinician is a meaningful clinical advantage.
Access opens up. People who would not otherwise attend, because of work, caring responsibilities, chronic illness, geographic distance, or anxiety about clinical environments, can have a full assessment. That is not a convenience issue. For a significant group of adults, it is the difference between getting assessed and not getting assessed.
Every clinical element is still here.
The setting changes. The assessment itself does not.
- A full 90-minute clinical interview, conducted personally by a HCPC-registered Clinical Psychologist.
- A detailed developmental history from childhood forwards.
- Careful screening for the conditions that commonly overlap with ADHD: anxiety, depression, autism, trauma, and mood disorders.
- QbCheck objective attention testing.
- A full written clinical report with diagnostic reasoning, not a one-page summary.
- A dedicated feedback session to talk through what the findings mean.
- A single all-inclusive fee, with no add-ons appearing later.
- A clear map of next steps, including treatment pathways, medication routes where appropriate, and coaching or therapy options if indicated.
None of these are abbreviated because the setting is online. In practice, the reverse is often true. Online sessions tend to be less rushed, because there is no travel overhead eating into the clinical hour at either end.
Respect for in-person, and a clear line against the mill clinics.
Some people strongly prefer to be seen in person. Often this is because they have spent years being dismissed by healthcare professionals and want to be physically in the room with someone who takes them seriously. That is a completely valid instinct. If you feel that way, I respect it entirely, and I am happy to signpost trusted colleagues offering in-person assessment. The right clinician for you might not be me, and I would rather you find the right fit than book the wrong one.
Separately, the public reputation of online ADHD assessment has been genuinely damaged by a small number of high-volume services that diagnose on the basis of a 20-minute call with a non-specialist, rubber-stamped by a reviewing psychiatrist. Those services exist. They are the reason the phrase "online ADHD clinic" raises understandable suspicion in many readers' minds.
What happens in a proper assessment has nothing meaningful in common with what happens there. The meaningful distinction is not online versus in-person. It is a 90-minute assessment by a Clinical Psychologist, with a full developmental history, objective testing, co-morbidity screening, a proper report, and time to discuss it, versus a rushed conversation whose function is to generate a prescription referral. If you have read anything alarming about online ADHD clinics recently, you were almost certainly reading about the second kind. I agree with the criticism. I also think it has very little to do with what a careful online assessment actually looks like.
If this has answered your question.
If the reasoning here feels like it matches the kind of assessment you are looking for, a free 15-minute consultation call is the simplest next step. No pressure, no sales script, just a conversation about your situation and whether an assessment with me is likely to be useful.
