Test-Retest Reliability of DiaMem
Starting soon
Conditions studied: Memory Functions, Cognition
In brief
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.
