Memory Impairment Clinical Trial
Official title:
Investigating the Efficacy of ApplTree, a Smartphone Reminding Application, on Prospective Memory Performance in Individuals Who Have Experienced a Stroke Using Single Case Experimental Design (SCED)
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.

Eligibility | Inclusion Criteria: - Community-dwelling individuals who have had a medically-confirmed stroke that occurred at least 3 months prior to recruitment - Participants must have self- or other-reported prospective memory difficulties - Participants must share accommodation with their nominated person - Participants must own and be competent in the use of a smartphone with a reliable internet connection.

Primary | Prospective Memory Log | The participant, their nominated person, and the Principal Investigator will discuss the participant's target prospective memory tasks and their intended completion times at the beginning of each week. These will be recorded on a Memory Log by the nominated person. Only the nominated person will have access to the Memory Log; they will be asked to store this privately so that it does not act as a memory aid or prompt for the participant. The nominated person will record whether these tasks are completed and, if so, whether they are completed on time and if prompting is required. | Completely weekly throughout baseline and intervention phases (10-13 weeks) | |
Primary | Text Message Log | Participants and nominated persons will be provided with times for the participant to send text messages to the Principal Investigator each week. Days and times will vary to prevent possible practice effects. Successful completion of sending text messages will be recorded by the Principal Investigator. | Completely weekly throughout baseline and intervention phases (10-13 weeks) | |
Secondary | Subjective ratings of worry and effort regarding prospective memory tasks | Participants and nominated persons will be asked to rate time spent worrying about their subjective effort regarding participants' prospective memory tasks for the previous week at the weekly check-in. Responses for each a rated on a 5-point likert scale ranging from 1=Never to 5=Always for Worry ratings and from 1=No effort to 5=A great deal of effort for Effort ratings. | Completely weekly throughout baseline and intervention phases (10-13 weeks) | |
Secondary | Unified Theory of Acceptance and Use of Technology questionnaire (UTAUT) | The UTAUT consists of eight domains (performance expectancy, effort expectancy, social influence, facilitating conditions, hedonic motivation, price value, habit, and behavioural intention). This measure will be adapted to assess participants' perceived usability, usefulness, and intention to use ApplTree after study completion. Responses are rated on a 7-point likert scale from 1=Strongly disagree to 7=Strongly agree.
Participants will be asked to complete the UTAUT after they have completed the baseline and ApplTree intervention phases. This will vary depending on duration of baseline period that participants were randomised to (5, 6, or 7 weeks). Participants will be invited to complete the UTAUT between 1 and 3 weeks post-intervention phase completion (e.g., to allow for things like holidays, illness, etc.). |
Completed once after baseline and intervention phases are completed (11-14 weeks to 14-17 weeks) | |
Secondary | End of study interview | Participants and nominated persons will be invited to separately provide subjective feedback regarding their experience of using ApplTree and whether they intend to use it in future, during an end-of-study interview with the Principal Investigator.
Participants and nominated persons will be asked to complete the end of study interview after they have completed the baseline and ApplTree intervention phases. This will vary depending on duration of baseline period that participants were randomised to (5, 6, or 7 weeks). Participants will be invited to complete the UTAUT between 1 and 3 weeks post-intervention phase completion (e.g., to allow for things like holidays, illness, etc.). |
Completed after baseline and intervention phases are completed (11-14 weeks to 14-17 weeks) |
