A landmark systematic review and meta‑analysis led by researchers at York University has found that digital mental‑health tools, particularly when paired with in‑person support, can produce sustained improvements in the wellbeing of children and young people.
Scale and main findings
The analysis pooled results from 57 peer‑reviewed studies encompassing more than 40,000 participants worldwide. Across those studies, the authors identified significant improvements in four psychological domains: emotional, behavioural, social and cognitive wellbeing. The most consistent and durable effects were observed where digital approaches were embedded within structured, supportive settings such as schools or combined with some face‑to‑face contact — commonly described in the paper as hybrid models.
- 57 studies reviewed.
- Data from >40,000 young people.
- Benefits found across emotional, behavioural, social and cognitive domains.
- Hybrid delivery showed the most consistent sustained effects.
What the researchers say
“Hybrid approaches, pairing digital tools with in‑person structure, held up better over time than fully virtual ones. We also found real gaps, including…,”
That observation comes from Kaitlin Di Pierdomenico, a York postdoctoral fellow and co‑author of the review. Lead author Professor Rebecca Pillai Riddell emphasised the need to implement digital tools thoughtfully and to prioritise inclusion:
“It's clear that digital tools must be embraced but only if we implement them thoughtfully, equitably, and with real‑world contexts in mind. We need to invest in research that includes the children most often left behind.”
Evidence gaps and equity concerns
While the overall findings are encouraging, the review highlights important limitations in the evidence base. Notably, there is a striking underrepresentation of studies focusing on marginalised populations and on very young children (ages 0–4). The authors caution that the existing literature therefore offers limited guidance on how well digital approaches serve those groups — a concern for policymakers seeking universally effective interventions.
The review further notes that the advantages of hybrid models were most apparent where digital interventions were delivered within supportive, structured settings, such as schools. That suggests implementation context — staff training, supervision, and integration with existing services — may be as important as the digital content itself.
Implications for policy and practice
For commissioners, clinicians and educators, the study provides evidence that digital tools can be a valuable component of youth mental‑health provision, but not a simple substitute for in‑person care. The findings support investment in blended programmes that combine digital resources with human support and rigorous evaluation. They also signal an urgent need to direct research and resources towards groups currently underrepresented in trials, to avoid widening health inequalities.
| Domain | Reported effect |
|---|---|
| Emotional | Significant improvements |
| Behavioural | Significant improvements |
| Social | Significant improvements |
| Cognitive | Significant improvements |
Crucially, the review stops short of claiming universal efficacy for all digital programmes. As with all meta‑analyses, observed effects reflect averages across diverse interventions, populations and settings; heterogeneity between studies means that effect sizes for any single programme may differ. The authors judge the evidence for sustained benefits from hybrid approaches to be of moderate certainty, indicating reasonable confidence but not conclusive proof.
Policymakers should therefore treat digital and hybrid interventions as complementary options within broader, evidence‑based mental‑health strategies for children and young people, with careful attention to equitable access, context‑sensitive implementation and ongoing independent evaluation.
Further work is needed to understand which elements of hybrid delivery drive lasting benefits, how to tailor programmes for marginalised groups, and how best to support younger children and their families. Until those gaps are closed, digital tools should be scaled alongside measures to monitor outcomes and prevent unintended inequalities.
