Optimising the acceptability and feasibility of acceptance and commitment therapy for treatment-resistant generalised anxiety disorder in older adults.

BACKGROUND

generalised anxiety disorder (GAD) is common in later life with a prevalence of 3-12%. Many only partially respond to cognitive behavioural therapy or pharmacotherapy and can be classified as treatment resistant. These patients experience poor quality of life, and are at increased risk of comorbid depression, falls and loneliness. Acceptance and commitment therapy (ACT) is an emerging therapy, which may be particularly suited to this population, but has not been tailored to their needs.

OBJECTIVES

to optimise the acceptability and feasibility of ACT for older adults with treatment-resistant GAD.

DESIGN

a person-based approach to ground the adapted ACT intervention in the perspectives and lives of those who will use it.

METHODS

first, we conducted qualitative interviews with 15 older adults with GAD and 36 healthcare professionals to develop guiding principles to inform the intervention. Second, we consulted service users and clinical experts and interviewed the same 15 older adults using 'think aloud' techniques to enhance its acceptability and feasibility.

RESULTS

in Stage 1, older adults' concerns and needs were categorised in four themes: 'Expert in one's own condition', 'Deep seated coping strategies', 'Expert in therapy' and 'Support with implementation'. In Stage 2, implications for therapy were identified that included an early focus on values and ACT as a collaborative partnership, examining beliefs around 'self as worrier' and the role of avoidance, validating and accommodating individuals' knowledge and experience and compensating for age-related cognitive changes.

DISCUSSION

Our systematic approach combined rigour and transparency to develop a therapeutic intervention tailored to the specific needs of older adults with treatment-resistant GAD.
