A digital program co-developed by a University of Texas psychologist was found to significantly reduce symptoms of depression four weeks after use, according to results published on Mar. 18 from one of the largest randomized controlled trials of single-session mental health interventions.
The study, published in Nature Human Behaviour, enrolled more than 7,500 adults in the United States who were experiencing elevated depressive symptoms. It is the first trial to show that a brief, self-guided digital session can lead to monthlong reductions in depression among adults, regardless of whether they are receiving therapy or medication or have experienced any other changes in their circumstances.
Alissa Mrazek, research assistant professor of psychology at the University of Texas, worked with Michael Mrazek at UTHealth Houston to develop Finding Focus. This interactive digital course and app helps users identify habitual interpretations that contribute to distress and teaches them how to reframe these thoughts constructively. The approach is based on cognitive science and mindfulness research and was refined over nine years through design iterations, pilot testing, and empirical evaluation.
An abbreviated version of Finding Focus was submitted to an open competition where scientists and clinicians presented single-session interventions for depression. These interventions were tested simultaneously against the same population under identical conditions. Of all those tested, only two showed lasting effects at four weeks; one was a version of Finding Focus.
“We kept asking ourselves what it would actually take for someone to feel genuinely better after a single 10-minute session,” Alissa Mrazek said. “If we could help someone learn to see situations through a slightly different lens, in a way that still felt true but made the best of the situation, then we believed we could move the needle on how they felt.”
The findings suggest broader implications for mental health care access. Millions of Americans face barriers such as cost, provider shortages or geographic limitations when seeking mental health support. Free digital tools that require only brief engagement may offer an accessible entry point alongside traditional models.
“This study tackles an urgent question. How we can deliver meaningful support to those without access to traditional mental health care?” said Lori Holt, chair of UT’s Department of Psychology. “By rigorously testing many brief digital interventions side by side, Mrazek and her colleagues point the field toward smarter ways to build scalable approaches to treating depression.”
