Couples therapy has an attendance problem before it has an efficacy problem. It requires two people to agree that it is needed, find the same free evening, travel to the same building, and pay for it. A great deal of it never happens for reasons that have nothing to do with whether it would have worked.
A systematic review in BMC psychology looked at what happens when you remove those obstacles. [pubmed-relationships-jul13-2026-source]
What the reviewers did
They searched for randomised controlled trials of digital, technology-based interventions intended to improve romantic relationship satisfaction, and found 15 eligible studies.
Of those, six could be combined statistically into a meta-analysis.
What they found
Most of the 15 reported significant improvements in relationship satisfaction, and those improvements were often still present at follow-up rather than fading once the programme ended.
The six pooled studies produced a moderate average effect.
The reviewers also found substantial heterogeneity, which they attribute to differences in programme design, participant population and delivery method.
The gap between fifteen and six
Nine of the fifteen studies could not be pooled.
That is not unusual and it is worth registering, because the number people remember from a review like this is the meta-analytic one, and here that number rests on 40% of the evidence. Studies get excluded from pooling when they measure relationship satisfaction on incompatible scales, at different intervals, or report results in a form that cannot be combined arithmetically.
The narrative finding, that most trials showed improvement, actually covers more ground than the pooled estimate does. It is just less quotable.
Why the heterogeneity matters more than the average
When studies disagree with each other more than chance explains, an average stops describing a single thing.
Some of these programmes probably worked well. Others probably did very little. The moderate average is a midpoint between them, and it is not an estimate of what any specific programme will do for any specific couple.
For a reader deciding whether to try one, the useful question the review cannot answer is which design worked. The reviewers point at programme design, population and delivery method as the likely sources of variation, which is an honest statement that the evidence is not yet fine-grained enough to say.
What it does not compare
Nothing here was tested against in-person couples therapy.
The comparisons were digital programmes against their control conditions. So the finding is that these interventions beat doing nothing or a minimal alternative, not that they match a therapist. Anyone reading this as permission to substitute an app for therapy is reading something the study did not test.
The access argument stands anyway
Even taking the modest reading, digital delivery addresses something real.
The barriers to couples therapy are disproportionately logistical rather than clinical, and they compound: two schedules instead of one, two people who both have to want it, a cost that is usually higher than individual therapy, and a willingness to sit in a waiting room together.
An intervention that is somewhat less effective and considerably more likely to actually happen can deliver more benefit in total. That is the case for this whole category, and this review is consistent with it without proving it.
What is actually stopping you getting help?
Couples therapy usually fails at a logistical step rather than a clinical one. Tick what is true.
0 of 6 ticked
Almost everything you ticked is a barrier a digital programme removes: separate times, no travel, lower cost, no waiting room. It is not equivalent to therapy and it is considerably better than the nothing that is currently happening.
Look at whether your items are practical or about willingness. If one partner does not want to go, that is not a scheduling problem and no format solves it. It is worth raising directly as its own conversation.
If the main blocker is that neither of you has got round to it, the useful move is to book something this week rather than to keep deciding to. Momentum is the scarce resource here.
If your relationship is struggling
Our relationships guide covers what tends to erode connection and what repair actually involves. If one of you is unwilling to attend anything, that is itself worth naming rather than treating as a scheduling problem.
