    Question Test-retest duration




    Hi

    Hi everyone. I'm new here.

    I have a problem here. I just finished my 1st pilot study on my instrument(questionnaire) and I would like to run test-retest method.

    How long do I need to wait before the re-test session?

    Thanks

    This is test and context specific (if I understand what you're asking). It's a trade off (like most things in stats) between making sure the time is sufficient that the test doesn't effect the second test though not so long as to attribute the change to other influences. My take is this is a researcher decision in which the whole context is considered and you have provided evidence for the decision you've made. Sorry I can't give you a hard and fast rule.
