Digital Tools Can Support Young People’s Mental Well-Being – but Human Contact Still Matters

Key Takeaways: 

• A York University-led review of 57 studies and more than 40,000 participants finds digital tools can improve young people’s emotional, behavioural, social and cognitive well-being.
  
• Hybrid models, pairing digital delivery with in-person contact, were the most consistently effective, with benefits sustained at follow-up.
  
• The evidence base has serious gaps: children from marginalised communities and those aged 0 to 4 are strikingly underrepresented.
  
  
  

Why this review matters

Children and young people are growing up with rising mental health challenges in an increasingly digital world, and those from marginalised communities carry a disproportionate share of that burden. Digital mental health tools have been promoted for years as a way to close the gap, on the assumption that anything delivered through a screen can reach further, faster and more cheaply than traditional services. Until now, the evidence for universal digital and hybrid interventions had never been pulled together and appraised as a whole.

A new landmark systematic review and meta-analysis led by researchers at York University changes that. Examining the effectiveness of universal digital mental health interventions, the study finds that digital tools can positively influence young people’s emotional, behavioural, social and cognitive well-being. The study is currently available online.

What the review examined

The review synthesised 57 peer-reviewed research articles and included data from more than 40,000 participants worldwide. Rather than focusing on interventions aimed at children and young people already identified as needing clinical support, it looked specifically at universal interventions, that is, those offered to whole populations regardless of individual risk. That distinction matters for anyone planning services at scale, because universal provision is where digital delivery is most often proposed as a solution.

The research was led by York University Faculty of Health Professor Rebecca Pillai Riddell, a nationally recognised expert in clinical psychology, alongside York postdoctoral fellow Kaitlin Di Pierdomenico.

“This study is the first of its kind to synthesize universal digital and hybrid interventions for child and youth mental health,” says Pillai Riddell. “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.”

Hybrid delivery outperformed fully digital approaches

The clearest signal in the analysis was that hybrid models, those that combine digital delivery with some in-person engagement, emerged as the most consistently effective approach. Moderate-certainty evidence supported sustained benefits across multiple psychological domains at follow-up, meaning the gains did not simply disappear once the intervention ended.

This finding pushes back against the assumption that a fully virtual programme is a straightforward substitute for one delivered face to face. The technology appears to work best when it is wrapped around human contact rather than used to replace it.

“This work looked at whether digital mental health tools help, under what conditions, and whose data we actually have,” says Di Pierdomenico. “Hybrid approaches, pairing digital tools with in-person structure, held up better over time than fully virtual ones. We also found real gaps, including underreporting of participant demographics and limited inclusion of younger children and marginalized populations, that matter so universal tools are developed to actually reach all children and youth.”

Benefits across four psychological domains

The analysis revealed significant improvements across emotional, behavioural, social and cognitive psychological domains. Effects were most consistent and most sustainable when digital tools were embedded in supportive, structured settings such as schools.

The implication for commissioners and practitioners is that the delivery context is not incidental to the outcome. A well-designed app or online programme placed into an environment with adults who can prompt, reinforce and follow up appears to perform differently from the same tool handed to a young person to use alone.

That emphasis on structured human contact places renewed weight on the interpersonal skills practitioners bring to digitally supported care.

Significant gaps in who the evidence represents

Alongside the positive findings, the study highlights a striking underrepresentation of research involving marginalised populations and younger children aged 0 to 4. This raises concerns about equity and inclusion in the current evidence base.

Two problems compound each other here. The first is straightforward absence: if the youngest children and those from marginalised communities are rarely included in trials, there is no reliable basis for claiming that universal tools work for them. The second is underreporting of participant demographics, which makes it difficult even to establish who has and has not been studied. Universal interventions are, by definition, meant to reach everyone, so evidence drawn from a narrow and poorly described sample is a weak foundation for population-wide rollout.

A national partnership behind the research

The York researchers worked with Strong Minds Strong Kids, Psychology Canada (SMSKPC) for the study, a national charity that promotes children’s mental well-being through psychological science.

“Our history has always been about promoting mental health. This research reinforces the urgency to get promotion right – and get it to the children who need it most,” says Anne Lovegrove, President and Executive Director of SMSKPC and a co-author on the study. “We undertook this study not only to inform our own work but to guide the entire sector toward what actually works in a rapidly changing digital landscape.”

The project was also generously supported by philanthropy from the Jackman Foundation, a longtime champion of youth mental health and of SMSKPC and York University.

What this means for practice

For practitioners and service planners, the review offers a more nuanced brief than either uncritical enthusiasm or blanket scepticism about digital mental health. Digital tools have a demonstrable place in supporting young people’s well-being. They appear to work best when paired with in-person structure, embedded in settings that already provide routine and relationships, and supported by adults who can hold the human side of the intervention.

Equally, the gaps identified in the evidence are a caution against assuming that a tool shown to help one group will help another. Extending reach is only meaningful if the children and young people who are currently least well served are actually included, both in the interventions themselves and in the research that evaluates them.

CCH insight

The strongest finding in this review is that digital tools worked best when paired with human contact and structure. That places the quality of practitioner conversations at the centre of digitally supported care.
