First seen Jun 25, 2026 · Last updated Jul 30, 2026 · Updated 3 times
Summary
This pilot study is testing a group-based cognitive-behavioural therapy (CBT) for people with generalized anxiety disorder (GAD) who have difficulty tolerating uncertainty. The treatment focuses on helping participants face uncertain situations through behavioural experiments. The study will include 12-20 adults with GAD and high intolerance of uncertainty, and will assess whether a future larger trial is feasible.

- What this could lead to
- If successful, this could show that a group format of this therapy is feasible and effective, making it easier to offer to more people with generalized anxiety disorder.
- What could go wrong
- This is a very small pilot study (12-20 participants) that is currently suspended. It is designed only to test feasibility, not to prove the treatment works.
