Mental health concerns are a leading cause of mortality for young people, making timely, high-quality, and affordable care a top priority. In Australia, however, the growth of youth mental health services has slowed, creating a critical gap between rising demand and available resources. Can digital solutions help close this gap?
Seyed Hossein Hosseini, a systems modeling research fellow at the University of Sydney's Brain and Mind Centre, and his team recently tackled this question in their paper, "Examining the Impact of Youth Mental Health Services Capacity Growth Trajectories and Digital Interventions on Youth Mental Health Outcomes: System Dynamics Modeling Analysis." The study, published in the Journal of Medical Internet Research, used a sophisticated simulation model to project the impact of different resource allocation strategies.
The research team developed a System Dynamics (SD) model using a collaborative approach that engaged a range of regional stakeholders. This model enabled simulation of future scenarios for youth mental health (YMH) outcomes—such as the prevalence of mental disorders, emergency department visits, and self-harm hospitalizations. Using these simulation analyses, the team examined the potential impact of digital health interventions and different growth trajectories for mental health service capacity, while accounting for implementation uncertainties and the influence of social factors such as childhood adversity.
The findings from this model suggest the needs for a more comprehensive, strategic approach to improving YMH outcomes. While digital interventions alone had a comparable impact to some specialized services, they were not enough to prevent worsening outcomes if face-to-face services declined. The most effective strategy is a combined approach: expanding specialized mental health services while simultaneously integrating digital technologies.
This research emphasizes the importance of looking at the entire mental healthcare system, rather than just single solutions. The results highlight that digital technologies are an effective way to address slow growth in the specialized mental health workforce, but they are most impactful when used to complement, not replace, traditional services. For sustained, long-term improvements in YMH outcomes, concurrent investment in a specialized workforce is essential.
The team chose to publish their work in the Journal of Medical Internet Research due to its high ranking in medical informatics and its alignment with the journal’s focus on digital health innovation and implementation. The study’s findings provide a strategic blueprint for policymakers and healthcare leaders, emphasizing that the most effective pathway to improving youth mental health is a balanced one.
