Running a Group Online or in a Room: A Decision Framework

You have a waiting list of people who say they’re isolated, a room that costs money to book, and a video call link that costs nothing. The instinct in most organisations is to default to whichever is cheaper or whichever staff are already set up to run. Neither is the right basis for the decision. The right basis is what the group is actually for, because digital and in-person delivery solve different parts of the loneliness problem, and the evidence on which does what is thinner than most funding pitches admit.

Two different problems, not one continuum

Isolation and loneliness are not the same thing, and the distinction matters more here than almost anywhere else in programme design. Isolation is about the objective size and structure of someone’s network. Loneliness is the subjective gap between the connection someone has and the connection they want. A national survey of adults 45 and older found that network size and diversity, along with physical isolation, were the strongest predictors of loneliness — and that people who never spoke to neighbours were roughly twice as likely to be lonely as those who did.

That framing has a direct implication for modality. If your group exists to expand someone’s network — more contacts, more weak ties, more people they could plausibly call on — digital delivery can do real work, because it removes the geographic and mobility barriers that keep networks small. If your group exists to close a subjective gap in felt connection, the evidence leans toward physical co-presence doing something a screen doesn’t replicate.

Eric Klinenberg’s work on social infrastructure argues that shared physical space itself shapes rates of contact — not just the activity that happens inside it, but the fact of being bodily present among others. Ray Oldenburg’s concept of the third place makes a similar point from a different angle: informal public gathering spots do work that scheduled, agenda-driven meetings don’t, because people can drift in and out of contact without it being the point. Neither of these frames has a video-call equivalent. A recurring Zoom group can be excellent at sustaining a network. It is a poor substitute for the third place.

What the evidence actually supports

Be precise about what you can claim, because practitioners are the ones who will have to defend it to a funder later.

Claim	Evidence status
Structured, purposeful group activity produces more benefit than contact alone	Reasonably supported — a qualitative synthesis of social prescribing found participants describing restored purpose and participation, not just social contact, as the mechanism of benefit
Social prescribing groups reduce loneliness for at least some participants	Moderately supported but heterogeneous — a systematic review found positive impacts across all nine included studies, with wide variation in design and no consistent outcome measure
Physical co-presence outperforms video contact for reducing loneliness specifically	Plausible from theory (Oldenburg, Klinenberg) but not directly tested against digital alternatives in the sources reviewed here
Digital groups are as effective as in-person ones at building network size	Untested at the level of rigorous comparison; American Heart Association reviewers flagged the near-total absence of intervention evidence as the central gap in the isolation and loneliness literature
Inconsistent measurement across studies limits comparison between modalities	Well supported — a 2023 review of the loneliness and isolation literature names inconsistent measurement as a structural barrier to exactly this kind of comparison

The honest summary: nobody has run the trial that tells you digital groups beat in-person groups, or the reverse, for reducing loneliness. What exists is theory about why physical space matters, and observational evidence that structured purpose matters more than mere contact, in either format.

A decision sequence, not a preference

Rather than picking a format and hoping, work through this in order.

1. Name the primary outcome. Network expansion, subjective loneliness reduction, skill-building, or service navigation. Each points a different direction.
2. Check who you can actually reach. Mobility-limited older adults, shift workers, rural participants, and people with social anxiety are often better served digitally at first. Digital-first is a reach decision, not a quality downgrade — but say so explicitly rather than treating it as a fallback.
3. Decide whether the format needs to change over time. Many of the strongest models start digital for low-stakes entry and move to in-person once trust exists. Plan the transition point before launch, not after attendance stalls.
4. Match facilitation skill to format. Reading a room and reading a gallery view are different skills. Facilitators need separate training for each, not a single briefing that assumes the techniques transfer.
5. Set the evaluation question before you set the format. If you cannot measure the outcome you named in step one in your chosen format, that is a reason to reconsider the format, not the measurement.

The gallery-view problem

The most common failure mode in digital groups built for connection is what’s worth naming as the gallery-view problem: a facilitator runs the session exactly as they would in a room — same agenda, same pacing, same expectation that side conversation will happen organically — and it doesn’t, because a grid of muted faces has no equivalent of the hallway, the tea urn, or the two minutes before the chairs are set out. Side conversation in a video call has to be engineered — breakout rooms, paired check-ins before the main session, a standing five minutes with no agenda — or it will not happen at all. Organisations that report digital groups “not working” have very often just ported an in-person structure onto a platform that doesn’t support incidental contact, then blamed the format rather than the design.

What this means in practice: decide the outcome before the platform. If the goal is expanding someone’s network of contacts, digital delivery is a legitimate primary format, not a stopgap — but you must build deliberate structures for informal contact, because the platform will not generate them on its own. If the goal is reducing felt loneliness for people who already have a network but no sense of belonging, weight your design toward physical co-presence, and treat digital-only delivery as a bridge to that, not an endpoint.

Where this sits alongside existing tools

If the honest answer is that your organisation doesn’t need to build a group at all, established platforms already run recurring in-person interest groups at scale — Meetup reports roughly 60 million members on a free tier built around exactly this model. For groups organised specifically around a shared meal, Timeleft runs weekly dinners that seat strangers matched by personality with no messaging beforehand, reporting more than three million guests seated globally. Neither is more effective than a well-run internal group by any evidence available here; they are simply existing infrastructure worth checking before you build a duplicate.

What this does not solve

This framework tells you how to choose and run a format. It says nothing about who shows up in the first place. Both digital and in-person groups still overwhelmingly reach people who already sought out a programme — people with enough functioning, enough trust in institutions, and enough spare capacity to register. The people social prescribing and connection programmes most want to reach — the severely isolated, the housebound, those without a smartphone or a car — are underrepresented in almost every evaluation cited in the literature reviewed here, digital or otherwise. Format choice improves what happens once someone arrives. It does not fix who arrives.
