I'm looking forward to your help .. I'm conducting an experimental, longitudinal study with random assignment.
I would like both groups (control group and trial group) to respond to a questionnaire at three different time points.
In addition, I would like the experiment group, before receiving the link to the questionnaire at the second time point, to hear a sound section and receive a link to it every day until the second measurement.
In the research I ask them to give one of the following details: Phone number or Email.
Hope you will be able to assist me,
Thanks in advance!
Maor.
