Plain English Summary

Background and study aims
Generalised anxiety disorder (GAD), characterised by a tendency to worry, is the most common anxiety disorder in older people. It is associated with distress, difficulty in coping, poor quality of life and increased disability. Medication and talking therapy are usually offered to older people experiencing GAD, but for many this treatment is unsuccessful. Guidance as to how best manage this treatment-resistant GAD in older people is lacking. Acceptance and Commitment Therapy (ACT) is a type of taking therapy helps people to learn different ways of coping with distressing thoughts and feelings, and how to take part in more activities that are meaningful to them. It is helpful for reducing distress in other conditions including anxiety, depression, life-limiting illness and long-term pain. The aim of this study is to find out how acceptable and feasible it is to develop and deliver a new treatment program based on ACT to older adults with GAD.

Who can participate?
Older adults aged 65 years and over who have been diagnosed with GAD that has not responded to treatment (either medication and/or conventional talking therapy).

What does the study involve?
In the first part of the study, around 15 older people with GAD take part in an hour and a half long interview about their experiences of treatment. Information collected from these interviews is then discussed with healthcare professionals in order to create a treatment programme using ACT techniques. The participants are then interviewed again for their views on the programme.
In the second part of the study, around 40 older people with GAD receive around 16 face-to-face sessions of ACT over 20 weeks plus usual care. These sessions are delivered within the GP surgery, outpatient clinic or participant's home by therapists attached to talking therapy and specialist mental health services. All therapists will receive training in ACT, as well as regular supervision. The sessions involve working with therapists to learn new skills to help better manage their GAD. At the start of the study and then again after 20 weeks, participants are asked to complete a number of questionnaires to assess levels of anxiety, worry, depression and quality of life, and to see how satisfied they are with the therapy they have received.

What are the possible benefits and risks of participating?
The main possible benefits include that participants will be given access to a novel form of talking therapy that is not yet available in the NHS for this condition. They will also be given a more in­depth screening assessment than they might otherwise receive as part of their routine NHS care. The main possible risks include that participants may experience a deterioration in anxiety and/or depression symptoms during the intervention (as it may not be beneficial for them) or distress during the interviews (e.g. when discussing their current difficulties). Participants will remain under the care of their GP or mental health professional during the study, and will be monitored and referred for further support if necessary.

Scientific titleA Feasibility study of Acceptance and Commitment Therapy for Older people with treatment-resIstant generalised anxiety Disorder
Study acronymFACTOID
Study hypothesisThe aim of this study is to investigate the feasibility of conducting a study to examine the clinical and cost effectiveness of Acceptance and Commitment Therapy (ACT) for older people with treatment-resistant generalised anxiety disorder.
Ethics approval(s)1. London – Camberwell St Giles, 09/05/2017, ref: 17/LO/0704

ConditionTreatment-resistant generalised anxiety disorder in older people
InterventionPhase 1:
Approximately 15 older people with generalised anxiety disorder (GAD) will be invited to participate in individual qualitative interviews lasting 1.5 hours in order to develop and adapt the intervention for this population. These interviews will explore positive/negative experiences of previous psychotherapy, facilitators/barriers to engagement in therapy, and the perceived suitability and relevance of an intervention based on Acceptance and Commitment Therapy (ACT) for treatment-resistant GAD in older people. Data from these interviews, together with discussions with experts in the field, will inform development of an intervention for this population. This will be based on the acceptance model of generalised anxiety disorder and existing ACT approaches. Once the intervention has been developed, the same set of participants from the initial interviews will be invited to participate in further individual qualitative interviews lasting 1.5 hours. These interviews will explore the acceptability and perceived value of the different components of the intervention, the practicalities of the intervention, and ways of optimising engagement. Modifications will be made to the intervention based on feedback from these interviews.

Phase 2:
Approximately 40 older people with treatment-resistant GAD will receive 16 1-hour face-to-face sessions of ACT over 20 weeks in addition to usual care. The intervention will involve helping participants to increase psychological flexibility through learning new skills, metaphors, experiential exercises and home practice tasks. These will aim to:
1. Reduce avoidance of difficult or uncomfortable experiences where such behaviour might be a barrier to life enriching activity
2. Reduce the amount of time people are "stuck in their head" ruminating about the past or worrying about the future
3. Reduce the degree to which people are caught up in negative or unhelpful thoughts about themselves, their situation or their identity and roles
4. Identify what really matters to them in their lives
5. Commit to doing personally meaningful activities that support what they value.
Sessions will be delivered within the GP surgery, outpatient clinic or participant's home by therapists attached to talking therapy and specialist mental health services. All therapists will receive training in ACT, as well as regular supervision. After 20 weeks, all participants will be followed up to assess how acceptable and feasible the intervention was. In addition, a sample of 15 participants and all therapists will also be invited to complete individual interviews lasting 1.5 hours to further assess acceptability and feasibility. These interviews will explore the perceived benefits and limitations of the intervention, together with any recommendations for revising it.

After 20 weeks, all participants will be followed up by an independent outcome assessor and the acceptability and feasibility of the intervention will be assessed.
Intervention typeOther
Primary outcome measureAcceptability:
1. Engagement rate is recorded as the number of eligible participants who consent to participate in the study and attend 60% or more of sessions by 20 weeks (session attendance records will be kept by therapists)
2. Satisfaction rate is recorded as the number of eligible participants who consent to participate in the study and give ‘satisfactory’ ratings of therapy using the Satisfaction with Therapy and Therapist Scale-Revised (Oei et al., 2008) at 20 weeks. There is no set definition of what constitutes “satisfactory” and so this will be defined as a total score of 21 or more on the Satisfaction with Therapy subscale.

Feasibility:
1. Recruitment rate is recorded as the number of eligible participants who consent to participate in the study by 10 months
2. Retention rate is recorded as the number of eligible participants who consent to participate that remain in the study until follow up at 20 weeks
Secondary outcome measuresAcceptability:
1. Failure to recruit rate due to lack of acceptability is recorded as the number of eligible participants who refuse to consent to participate in the study by 10 months due to lack of acceptability of the intervention
2. Attrition rate due to lack of acceptability is recorded as the number of eligible participants who consent to participate in the study that drop out due to lack of acceptability of the intervention by 20 weeks
3. Treatment credibility/expectancy is measured using the Credibility/Expectancy Questionnaire at 1 week

Feasibility:
1. Referral rate is recorded as the number of eligible referrals to the study overall and in each referral subgroup (self-referral, GPs, GP list searches, Improving Access to Psychological Therapies services, and Community Mental Health Teams) by 10 months
2. Failure to recruit rate for reasons other than lack of acceptability is recorded as the number of eligible participants who refuse to consent to participate in the study by 10 months for reasons other than dissatisfaction with therapy
3. Attrition rate for reasons other than lack of acceptability is recorded as the number of eligible participants who consent to participate in the study that drop out for reasons other than dissatisfaction with therapy by 20 weeks
4. Treatment integrity is measured using the ACT Treatment Integrity Coding Manual at 20 weeks
5. Treatment adherence is measured using the Adherence Checklist at 20 weeks

Patient-reported outcome measures:
1. Anxiety is measured using the Geriatric Anxiety Inventory at baseline and 20 weeks.
2. Worry is measured using the Penn State Worry Questionnaire at baseline and 20 weeks.
3. Depression is measured using the Geriatric Depression Scale-15 at baseline and 20 weeks.
4. Health-related quality of life is measured using the EQ-5D-5L at baseline and 20 weeks.
5. Service utilization is measured using a short modified version of the Client Service Receipt Inventory at baseline and 20 weeks.
6. Psychological flexibility is measured using the Acceptance and Action Questionnaire-II at baseline and 20 weeks.
