Mental health concerns among young adult populations have increased in recent years, with standard treatment approaches presenting many undue barriers (e.g., time and cost constraints and limited availability of therapists). Single-session interventions (SSIs) have been explored as an alternative, scalable intervention to address these barriers to care. We evaluated the acceptability and feasibility of a SSI in a real-world setting and found promising effects of the SSI on symptoms of depression in a young adult population. Given these findings, we offer support for the SSI as an accessible treatment alternative to perhaps be integrated into tiered care treatment models or settings with limited access to care.
