Variable: Participation period



Variable: Participation period

The 'Participation period' variable selects users based on whether they answered an array of questionnaires between a specified start and end date.The start date check box specifies whether we compare the variable date with the users start date of answering the questionnaire or his end date (it may happen that a user took more than a day to answer a questionnaire). If 'start date' is unchecked it means we will compare the date with the date the user finished answering the questionnaire. It is possible here to select more than one questionnaire and the variable is true for a user as long as he just fulffilled the participation criteria of at least one of them!
