Acceptance and commitment therapy for older people with treatment-resistant generalised anxiety disorder

Medical Conditions

Treatment-resistant generalised anxiety disorder (TR-GAD)


This information is provided directly by researchers, and we recognise that it isn't always easy to understand. We are working with researchers to improve the accessibility of this information. In some summaries, you may come across links to external websites. These websites will have more information to help you better understand the study.


Generalised anxiety disorder (GAD), characterised by a tendency to worry, is the most common anxiety disorder in older people. Medication and talking therapy are usually offered as forms of treatment, but many do not find them helpful. Guidance on how to help older people manage GAD when it does not respond to such treatments is lacking. In a previous study (the FACTOID study), we developed and tailored a talking therapy intervention to the psychological, physical and cognitive needs of older people with treatment-resistant GAD (TR GAD). This was based on Acceptance and Commitment Therapy (ACT); a form of talking therapy that helps people learn how best to live with distressing thoughts, feelings and sensations, while still doing things that really matter to them. This showed that tailored ACT was acceptable to older people with TR-GAD and it may help improve anxiety, depression and coping. The aim of CONTACT-GAD is to find out whether tailored ACT is helpful for older people with TR-GAD and whether it represents value for money in a larger clinical trial.

Start dates may differ between countries and research sites. The research team are responsible for keeping the information up-to-date.  

The recruitment start and end dates are as follows:

24 May 2023 31 Jul 2025

Participants will be allocated at random to either have tailored ACT plus usual care (intervention group) or usual care alone (control group). We will test whether ACT plus usual care leads to a greater reduction in anxiety than usual care alone at 6 months. We will follow people up at 12 months to see if any effects are maintained. We will also look at ACT's value for money, quality of life, depression, adverse effects, satisfaction with ACT and usual care, adherence and behaviour change.


People aged 60 years and over with TR-GAD that has failed to respond to a previous drug and/or talking treatments or those with TR-GAD who did not want to start or continue these treatments previously and still have symptoms of GAD

The main possible benefit is that participants may receive a new type of psychological therapy that has been shown to benefit people with other mood disorders such as depression. The main possible risk is that participants may experience distress when discussing their current situation in assessments and therapy sessions, or participants' mood may worsen after receiving ACT. Participants remain under the care of their clinical team during the study and will be monitored and referred for further support if necessary.
