This tool is designed to create a QSF file for our M2C2 cognitive activities, allowing for integration into Qualtrics. Once generated, the QSF file will need to be imported into Qualtrics, after which you can add survey questions as desired. Please note that JavaScript must be enabled for this tool, which is not available in the free version of Qualtrics.
Follow these steps to import the QSF file:
The suggested default parameters are designed for brief assessments on mobile devices. Each takes approximately one minute to administer and is intended to be repeated multiple times a day over several days.

The suggested default number of trials is 12. The number of trials MUST be an EVEN number.
IMPORTANT: The number_of_different_colors_trials should be ½ the total number of trials (e.g., if number_of_trials = 20, then the number_of_different_colors_trials = 10). Please make sure to also update this parameter.
The number_of_different_colors_trials parameter is the number of trials where the shapes will change colors from the study phase to the test phase, where the correct answer chosen would be “Different.” The suggested default is 6 for this parameter to coincide with ½ of the number of default trials, which is 12.
IMPORTANT: The number_of_different_colors_trials should be ½ the total number of trials (e.g., if number_of_trials = 20, then the number_of_different_colors_trials = 10).
The shapes_presented_duration_ms parameter is how long the shapes are shown in milliseconds. The default is 500 ms, but for older adults with suspected impairments or elevated dementia risk, it is suggested to make this 2000 ms.
