Background: Digital mental health interventions (DMHIs) have the potential to improve the efficiency, accessibility and effectiveness of mental health services for young people, with the potential to reach socioeconomically and digitally marginalised young people with mental health needs who would otherwise not seek help in person. This review aims to investigate the characteristics, acceptability and efficacy of DMHIs specifically developed for socioeconomically and digitally marginalised youth. Method: Key databases were searched widely and systematically (EMBASE, MEDLINE, PsycINFO, OpenGrey). Final inclusion in this review required studies to evaluate DMHIs specifically targeting socioeconomically and digitally marginalised children and young people through a broad range of research designs. Results: Ten studies, describing seven DHMIs, were included in this review. Studies varied in terms of methodology, population, intervention, outcome measures, technologies used and methodological quality. Qualitative and quantitative results are synthesised across three key phenomena of interest: effectiveness, acceptability and feasibility. Findings suggest that there is moderate but limited evidence supporting DMHIs for improving mental health outcomes among these populations. Conclusions: While there is moderate evidence suggesting that digitally delivered interventions can be effective in improving mental health outcomes among socioeconomically and digitally marginalised youth, more high-quality research is needed in order to determine whether DMHIs can fully bridge the so-called 'digital divide'.
Key Practitioner Message• Digital mental health interventions (DMHIs) for socioeconomically and digitally marginalised youth are not widely researched. • This systematic review fills a gap in the literature by investigating digitally delivered interventions, utilising a range of technologies, to improve mental health outcomes among digitally and socioeconomically marginalised youth. • DMHIs appear to be a promising option for meeting the mental health needs of socioeconomically and digitally marginalised children and young people, although the current evidence base is limited. • More high-quality research is needed to fully determine whether DMHIs can truly bridge the 'digital divide'.
