Official title
An Exploratory Study on the Test-Retest Reliability of the Memory Function Assessment Tool DiaMem
Overview
The goal of this observational study is to learn how reliable the DiaMem memory assessment tool is when used repeatedly over a short period. The main question it aims to answer is: • How consistent are the DiaMem test scores when the same person takes the test multiple times? Researchers will also compare DiaMem with another digital memory test called MemTrax to gather initial information. Participants will: * Be adults aged 60 or older. * Complete a standard memory test and a thinking skills test. * Be randomly split into two groups (A and B). * Take memory tests once a day for 6 days in a row. Group A will take the DiaMem test 3 times first, then the MemTrax test 3 times. Group B will take the tests in the opposite order. • Answer a short questionnaire about how easy the tests were to use.
Primary outcome measures
- Test-retest reliability of the DiaMem total score [Time frame: Days 1 to 3 in Group A and Days 4 to 6 in Group B]
Secondary outcome measures (4)
- Test-retest reliability of the MemTrax accuracy score [Time frame: For Group A, sessions occur on Days 4 to 6; for Group B, on Days 1 to 3.]
- Actual completion time for the DiaMem and MemTrax assessments [Time frame: 6 days (Recorded at each of the 6 assessment sessions)]
- Mean DiaMem and MemTrax scores by age group and education level [Time frame: At completion of all 6 assessment sessions (Day 6)]
- System Usability Scale (SUS) score for the DiaMem and MemTrax tools [Time frame: Assessed once per tool: after the first DiaMem session (Day 1 for Group A / Day 4 for Group B) and after the first MemTrax session (Day 4 for Group A / Day 1 for Group B)]
