Online CBT vs in-person: what the evidence actually says

Randomised trials consistently find therapist-delivered online CBT works as well as in-person CBT for anxiety and depression. The honest differences are practical — convenience, catchment, and a handful of situations where in-person still wins.

That single sentence answers the question most people arrive with, so the rest of this page is the detail behind it: what the research actually shows (and what it does not cover), where online is genuinely the better format rather than just the convenient one, where in-person keeps a real advantage, and — since I work online myself — how to make video sessions work properly.

What the research shows

The equivalence finding is not new and not marginal. Over roughly fifteen years, randomised controlled trials and meta-analyses have compared therapist-delivered online CBT with face-to-face CBT for the common presentations — anxiety disorders, depression, panic, social anxiety — and repeatedly found no significant difference in outcomes. The therapeutic relationship, one of the most reliable predictors of whether therapy works, develops over video at very similar rates to in a room. The core techniques of CBT — formulation, behavioural experiments, exposure work, restructuring unhelpful thinking — translate almost entirely intact.

One distinction matters enormously here, and most comparison articles blur it: the equivalence evidence is for live sessions with a real therapist, delivered over video. It is not evidence for self-guided apps, chatbots, or text-only subscription services. Those are different products with a thinner, more mixed evidence base. When someone asks "does online therapy work?", the honest answer depends entirely on which of those things they mean. A weekly 50-minute video session with a trained, supervised therapist is the format the trials tested — and it holds up.

This surprises people who have never tried it. The intuition is that removing the shared room must remove something essential. In practice, video preserves what actually does the work — facial expression, voice, real-time conversation — and what gets lost turns out to matter less than everyone assumed.

Where online is genuinely better

Not just "as good" — there are situations where online is the stronger clinical choice, and they get underplayed because they sound like convenience arguments. Some of them are not.

• Exposure work happens where the problems live. If your difficulty involves rituals at home, checking at your own front door, or triggers in your own kitchen, online therapy lets us work with the real thing in real time — not a role-play of it in a clinic that looks nothing like your life. For a lot of anxiety work this is a genuine clinical advantage, not a compromise.
• No travel, no waiting rooms. A 50-minute session costs you 50 minutes, not half an afternoon. That sounds trivial until you are trying to sustain weekly therapy around a job — drop-out from therapy is real, and friction feeds it.
• Your choice of therapist stops being a postcode lottery. In a room, you choose from whoever practises within driving distance. Online, you choose from the whole country — on fit, approach and price rather than geography.
• Social anxiety often finds it easier to start. Getting to a clinic and sitting in a waiting room is itself a social exposure, and for some people it becomes the reason to cancel. Starting from your own room lowers the cost of showing up, so the actual work begins sooner. (Later in treatment, real-world exposure comes back in deliberately — but by then you have momentum.)

Where in-person still wins

An online therapist telling you online is always fine would deserve your suspicion, so here is the honest counter-list.

• Severe and complex presentations. Where there is significant risk, dissociation, or a heavy trauma history, in-person work is often the better container — partly because the shared physical space genuinely helps regulate intense sessions, and partly because managing a crisis is more straightforward in a room. Any careful therapist will discuss format openly at assessment in these situations.
• No privacy at home. Therapy through a thin wall from a partner, flatmate or family member does not work. If your home cannot give you a reliably private hour, a therapist's room provides something your house cannot.
• Screen fatigue is real. If your working day is already eight hours of video calls, a ninth can feel like more of the same rather than a different kind of hour. Some people need therapy to be a different place.
• Some people simply prefer the ritual of a room. The journey there, the door closing, the journey back to digest — for some people that frame is part of what makes therapy feel real. The evidence says outcomes are equivalent; it does not say preferences are irrelevant. A format you will actually keep showing up to beats a marginally convenient one you quietly resent.

What makes online CBT work well

Format is only half the question — the other half is setup, and it is almost entirely within your control:

• A private space with a door that closes. A parked car works surprisingly well when the house is full.
• Headphones. They keep the session private in both directions and make the conversation feel closer — a small change with an outsized effect.
• A decent connection and a propped-up device. A laptop beats a hand-held phone; repeated dropouts genuinely disrupt the work, so sit where the signal is good.
• Treat it like a real appointment. Ten minutes of buffer either side, water within reach, notifications off. The people who get the most from online therapy are the ones who do not treat it as one more call in the calendar.

How I work, and why

My own practice is online, across the UK and Ireland — and that is a choice, not a fallback. I trained and started practising in a world where the equivalence evidence was already solid, so I built the practice around what online does best: no room-hire baked into the fee (one reason my sessions cost £60 rather than £90), clients choosing me on fit rather than postcode, and exposure work done in the environments where people's difficulties actually happen. If in the free call it becomes clear that in-person would serve you better, I will say so and point you in the right direction — the format should serve the work, not the other way round.

Questions to ask any online therapist

Whoever you end up working with — me or anyone else — these five questions sort the careful online practitioners from the rest:

1. What platform do you use, and is it secure? You want a named, encrypted video platform — not "we'll sort something out".
2. Are sessions live video, or chat and messaging? The strong evidence is for live video. If you are paying for therapy, know which product you are buying.
3. What happens if the connection drops mid-session? A good answer is a plan: rejoin, fall back to phone, make up lost time. A shrug is a warning sign.
4. Where are you based, and are you insured? A UK or Ireland-based therapist with professional insurance and clinical supervision is accountable in ways an anonymous profile on a global app is not.
5. What are your qualifications, and who supervises your work? Any honest therapist answers this comfortably, at any career stage. I am an earlier-career therapist and I will tell you exactly that.

Try it with a free 15-minute video call

The neat thing about a free 15-minute video call is that it answers two questions at once: whether we are a good fit, and whether online actually feels right to you — because the call runs on the same setup as a real session. If the format feels wrong, you have found that out for free in a quarter of an hour, and I will happily say so and suggest alternatives. No pressure either way, no obligation to book anything afterwards.
