Anxiety disorders and post traumatic stress disorder
My research mainly focuses on anxiety disorders and posttraumatic stress disorder. My Wellcome Trust funded group uses experimental paradigms and prospective longitudinal studies to identify psychological factors that help explain the development and maintenance of these disabling conditions. The results of these studies help us develop new psychological treatments that target these factors. The treatments are evaluated in randomised trials and cohort studies.
The cognitive therapy programme for PTSD developed by our group has been shown to be highly acceptable to patients and very effective. It has been successfully disseminated to provide effective treatment services for victims of the bombings in Omagh and London, and to National Health Service clinics.
Current research projects investigate whether the treatment can be delivered more efficiently, and what the mechanisms of treatment are. Experimental studies investigate mechanisms of intrusive memories after trauma.
