Researchers at Mass General Brigham have developed a novel smartphone app, HabitWorks, aimed at improving mental health by addressing interpretation bias. This is the tendency to draw negative conclusions in uncertain situations. This cognitive pattern is strongly linked to anxiety and depression.
Results from a randomized controlled trial, published in the Journal of Consulting and Clinical Psychology, indicate that the app can significantly improve users’ thinking patterns, reduce symptom severity, and enhance overall functioning.
Short, personalized exercises
According to senior author Courtney Beard, negative interpretations directly influence emotional responses and behavior. HabitWorks translates evidence-based psychological principles into short, game-like exercises designed to help users recognize and adjust these patterns.
Unlike traditional digital therapies that replicate long sessions, HabitWorks offers brief, five-minute interventions that align with everyday smartphone use. Lead author Alexandra Silverman highlights that this approach improves usability and integration into daily routines.
Strong clinical results
The study included 340 adults across 44 U.S. states, randomly assigned to either a four-week HabitWorks program or a control group completing self-assessments. Participants using the app showed significantly greater improvements in interpretation bias, mental health symptoms, and daily functioning.
Notably, the app achieved high retention rates, with nearly 78% of participants still active after four weeks. An important benchmark in digital health, where user drop-off is common. Access to evidence-based mental health care remains limited due to provider shortages, cost barriers, and stigma. While digital tools offer potential solutions, many lack rigorous validation.
HabitWorks addresses this gap by combining clinical evidence with user-centered design. Although not yet publicly available, further research will explore long-term effects and identify target populations, paving the way for broader implementation in scalable mental health care.
App for mental recovery support
Last year, researchers at the Medical University of South Carolina developed Bounce Back Now, a mobile app designed to support mental recovery after disasters. The innovation responds to growing pressure on healthcare systems and the fact that only a minority of people with post-disaster psychological complaints seek help.
The app builds on decades of research into digital interventions and focuses on self-management, early detection, and accessible care. It offers tools such as mood tracking, relaxation exercises, behavioural activation, and more in-depth modules like writing therapy and sleep support.
Studies show the app can reduce the risk of PTSD and depression, particularly among young people. A randomized trial found that users of the full app experienced faster mental health improvements than those using a simplified version. Integration into regular care pathways and co-creation with users are key to its success, supporting scalable, patient-centered digital mental health care.
