Background: Prospective memory impairment is common following stroke and can significantly impact daily functioning and quality of life. Studies show that technological memory aids, including smartphone applications, are effective in helping compensate for PM difficulties. Wilson (2021) investigated the efficacy of ApplTree, a smartphone reminder application, in three community-dwelling stroke participants with PM difficulties using a multiple baseline across participants, single case experimental design (SCED). Results indicated that ApplTree did not lead to statistically significant improvements in prospective memory performance. However, methodological issues (e.g., self-report and limited response format on Memory Log regarding prospective memory task completion) were highlighted that may have made it difficult to detect any positive effects of ApplTree.~Aims: The proposed study will replicate Wilson (2021) whilst addressing these methodological issues. It is hypothesised that prospective memory performance will improve from baseline to intervention phases, and that ApplTree will be acceptable to participants.~Methods: Participants who have had a stroke and currently experience prospective memory difficulties will be randomly assigned to a 5-, 6- or 7-week baseline phase, where they will continue to do what they normally do to remember tasks in the future. They will then complete training in the use of ApplTree and a 5-week intervention phase, where they will use ApplTree to remind them to complete prospective memory tasks. This will allow us to compare prospective memory performance with and without ApplTree to see if ApplTree makes any difference. A nominated person (e.g., a partner) will record prospective performance during baseline and intervention phases on a Memory Log. Subjective feedback from participants and their nominated person about their experiences of using ApplTree will be gathered after study completion.~Practical Applications: The Stroke Association (2021) have highlighted cognitive and memory difficulties as a top priority for stroke rehabilitation research. This study will contribute to the growing literature on neuropsychological rehabilitation for stroke survivors. Should ApplTree demonstrate efficacy for improving PM performance and be acceptable to participants, it may have utility for stroke rehabilitation.
After a stroke, people can experience memory problems, including difficulty remembering to do things in the future - termed prospective memory. This can impact their ability to carry out important activities of daily living (e.g., taking medication), independence, and quality of life. Technology-based memory aids, including smartphone applications, can compensate for memory difficulties and are recommended as a 'practice standard' for improving prospective memory impairment following stroke. ApplTree is a smartphone application that was designed for people with memory and attention problems. Users can enter details of future tasks and events and ApplTree then prompts them to remind them to complete these at a pre-specified time. This study will investigate whether ApplTree helps people who have had a stroke and experience prospective memory difficulties to successfully complete prospective memory tasks. It will also explore whether they find ApplTree helpful and easy-to-use.
