Single-Session Interventions Produce Small Monthlong Depression Reductions

Researchers published in Nature Human Behaviour report a 2024 randomized controlled trial assigning 7,505 U.S. adults to one of twelve self-guided, under-10-minute single-session interventions or a control. Two interventions — Interactive Cognitive Reappraisal and Finding Focus — produced small monthlong reductions in depressive symptoms (≈4% greater improvement versus control). The brief, free exercises could scale to broaden access and supplement traditional mental healthcare.
