Stressful or traumatic events are common, and can have a lasting impact. Trauma talking therapy is recommended for people who are experiencing difficulties due to such events. Small studies have shown that it is safe and can be helpful for people with problems like voices, visions, and sensations, or worries about being unsafe or persecuted. However, people with these kinds of problems are rarely offered trauma talking therapy in the NHS.

The National Institute for Health and Care Excellence (NICE) have recommended that a large study should evaluate this therapy in the NHS, to fill a major gap in treatment availability.
