I am preparing questionnaire on self medication habit of consumer in which one of the item of standardized scale is about asking for reason for self medication : Question is like Which is your most preferred reasons for self medicating or using drugs without a doctor’s prescription? then in options 7 reasons are mentioned . But i am confused is it the right way to ask or i should draft separate question for each of the option and note consumer preference on a 5 point likert scale as i think that way i can apply more statistical test while in the former case only possible form is Chi-square test.. also comment can i use both ways in he same questionnaire. please feel free to comment suggest or modify my question and give appropriate answer.
