Hello,
I'm new to this platform, and this is my first ever post in here. So, please excuse me in advance if I happen to cause any inconvenience. Coming back the question;
I have just adapted a questionnaire which was originally used in a PhD study with university students, but the thing is I cannot pilot it because it is meant to be used only after an intervention. In other words, the questionnaire don't make sense to anyone if they don't get the treatment in my study. By the way, the study will take place in a secondary and high school and the questionnaire will be given to the students in the experiment group in there.
In this case, just adapting the questionnaire and asking some experts for advice would make it reliable and valid enough to be used for a PhD thesis?
Thanks a lot in advance for taking time to have a look at this.
Best regards,
Yusuf
