Create longitudinal study with 4 waves (each 2 weeks). First and last wave with same questions, 2nd and 3rd wave with reduced questions than the other two.
I need to use inclusion criteria that will create 4 different studies.
Create questionnaire in Qualtrics, approximately 140 questions (likert type many of them)
Can we briefly talk to discus details and questions?
Thanks,
Ruben.
