To evaluate the feasibility of Acceptance and Commitment Therapy for people with acquired brain injury.

A process evaluation of the BrainACT treatment was conducted alongside a randomised controlled trial.

Psychology departments of hospitals and rehabilitation centres.

Tweny-seven participants with acquired brain injury and 11 therapists.

BrainACT is an Acceptance and Commitment Therapy adapted for the needs and possible cognitive deficits of people with acquired brain injury, provided in eight one-hour face-to-face or video-conference sessions.

The attendance and compliance rates, engagement, satisfaction, and perceived barriers and facilitators for delivery in clinical practice were investigated using semi-structured interviews with participants and therapists and therapy logs.

212 of the 216 sessions in total were attended and 534 of the 715 protocol elements across participants and sessions were delivered. Participants were motivated and engaged. Participants and therapists were satisfied with the intervention and participants reported to have implemented skills in their daily routines acquired during therapy. Key strengths are the structure provided with the bus of life metaphor, the experiential nature of the intervention, and the materials and homework. Participants and therapists often preferred face-to-face sessions, however, when needed video-conferencing is a good alternative.

BrainACT is a feasible intervention for people with anxiety and depressive symptoms following acquired brain injury. However, when the content of the intervention is too extensive, we recommend adding two extra sessions.
