Participant FAQ

We responsed here to common questions we receive via email from participants. For general information about the study, please visit the Study FAQ.

 

What to do if I need to change the start date?

 

If you would like to push back your start date with 1 week:

Email us at microdose-study@protonmail.com and we can change the start date for you within our database.

 

If you would like to push back your start date with more than 1 week:

Go to the bottom of the welcome email you got from us and click 'Withdraw from study'. This will delete your current registration within the system and then you will be able to re-register with a new starting date. In this case you will have to complete the baseline measures again that are sent in the welcome email.

 

The cognitive tests are not loading / displaying.

 

Make sure you use the latest version of your browser. Our systems are extensively checked with the latest versions of Chrome, Safari and Firefox, but errors may occur on older versions. 

 

Can I use the schedule from Figure 1?

 

Yes, you can. Using this option also simplifies Step 4 of the set-up process (when placebo / microdose capsules are assigned), because you can read of from the figure what capsule is assigned for each day.

 

When should I complete the tests?

 

You need to complete all test on the same day when the test was received during the dosing period, i.e. during the 4 weeks when you take the capsules. The other tests, pre-, post-dosing and long term follow-up need to be completed within a  week of receiving the invitations.

 

I am not able to complete the setup by my start date, what should I do?

 

Go to the bottom of the welcome email you got from us and click 'Withdraw from study'. This will delete your current registration within the system and then you will be able to re-register with a new starting date. Please note that this will delete all tests you have completed so far, so you will have to complete those again.
