Hello,
I have a graduation project this semester, and due to time limitation I need a published study talking about any topic related to the Health Insurance OR National Health Insurance in Saudi. the study prefer to be about the awareness, satisfaction any topic the its data can be collected easier from publication in a city level not country.
The study need to be valid and the methodology as well, the survey need to be applicable in Saudi as well.
So, the main goal here is to duplicate a published study in Saudi. Also secondary data is accepted as well.
Finally, if you find one, share it with me first to make sure it is applicable before writing a breif proposal for the supervisor.
