I am doing my disseration on workplace mentorship for millennials in Hong Kong. A very under-studied tpoic. It is a qualitative in-depth interview study focusing on mentor perspectives. Want to ask if measurement scales like GMMP, MFS, MCA etc are applicable only to quantitative survey questionnaire? If and how can I use exiting Quan scales to build my interview questions for 1-on-1 interviews with participants ? Or is it simply not suitable approach to apply QUAN scales to QUAL studies? Thank you very much
