Hi Peter. In my opinion you should not necessarily "fabricate" a research question. Start by looking around, down to reality. What are the big problems that you see in your setting related to non-communicable diseases? Do you think that research can contribute to solve these problems? How so? Once you get an idea out of your reality, start building the research question. Hope this helps.
Research questions need to be devised with the aim of responding to existing problems in the area concerned. A research question relevant else where might not be important in your setting. It is worthwhile to review the existing data or report in your vicinity, discuss with colleagues and experts in your area to help you come up with a research question/ topic.
Hi Peter, non-communicable disease is a very large topic area. If you are interested in diabetes can I suggest you search for Timothy Skinner on google scholar and you will get an idea of all kinds of research that has been done on chronic disease knowledge attitudes and practice both from a patient perspective and from a health professional perspective. You may find something that you might like to replicate or it may give you some ideas on what might be interesting and useful in your own practice area.
