Adapted Solution Focused Brief Therapy in Post-stroke Aphasia (SOFIA Trial): a Feasibility Study

Background and Aims Around one third of people who have a stroke will experience aphasia, a language disability that can affect talking, understanding, reading or writing. The psychosocial impact of aphasia is considerable: those living with chronic aphasia are at risk of social isolation and depression. One potential intervention is Solution Focused Brief Therapy (SFBT). SFBT is an approach to building positive change in a person's life. It builds up a picture of a client's preferred future; encourages a person to notice positive signs of change; explores personal resources, skills and resilience; and acknowledges the impact of the stroke on a person's life and identity.

The current project builds on a small-scale proof-of-concept study that explored SFBT with five people who had mild to moderate aphasia, at least two years post stroke. There were improvements in participants' mood and participation and participants found the therapy highly acceptable.

The main aims of the current project are to assess: [1] the acceptability of SFBT to people with varying presentations of aphasia; and [2] the feasibility of conducting a future definitive trial investigating clinical and cost effectiveness.

Methods The overall study will last for 38 months (November 2016 to December 2019), and comprise a Development Phase (year 1) and a single-blind, randomized, wait-list controlled, feasibility trial with nested qualitative research comparing SFBT plus usual care to usual care alone (years 2 and 3).

During the Development Phase the investigators will develop the therapy manual and fidelity checking processes, train the clinicians, and finalize the protocol. Phase One has been informed through four workshops with the Aphasia Advisory Group, comprised of four people with aphasia and one carer, who advised on the study protocol and trial documentation. The investigators also conducted a pilot study with four people who have severe expressive and receptive aphasia where the investigators trialed the assessment and therapy protocol, and explored adapting the therapy for people with severe communication difficulties.
