What was grouped together
The review included 33 randomized trials and 1,285 participants. ‘Digital’ covered different tools, targets, schedules and comparison groups, including technology- and robot-based approaches.
Pooling can estimate an overall pattern, but it can also hide differences between products and purposes.
Why the headline needs caution
The authors reported greater average improvement for digital interventions. Results differed depending on whether the control was active, usual care, a waitlist or no treatment.
That matters because extra attention, novelty and expectation can influence outcomes. A comparison with an active alternative often answers a harder and more useful question than a waitlist comparison.
A practical app checklist
Ask whether the exact product has been studied, whether participants resemble the intended user, what outcome changed, how long it was measured, and who funded the work.
Also examine privacy, sensory load, accessibility, cost and what happens to personal data. Clinical evidence does not automatically answer those product questions.
Limitations to keep in view
- The review combined highly different technologies and targets.
- Its literature search ended in November 2022.
- Results from research tools may not transfer to commercial products.
