Hello everyone,
I am validating an existing questionnaire (it has been validated in different countries and languages) in my country. Unfortunately, the data that we have gathered are unequal; 80% are females and 20% are males. Does this affect the validation process or am I good to proceed with data analysis?
Thanks,
Sara
It affects some indicators, but the method is the same as. What study do you want to conduct?
Babak Jamshidi Well, I have translated a questionnaire in Persian and want to validate it as well. It is about narcissism.
Dear Sara Hoseingholizade ,
I don't think this is a problem. We usually do not consider the applicability of a validation procedure being dependent on a specific demographic. There is no requirement for questionnaire validation to use a stratified sample. If that was the case then we would need to stratify the sample about every possible demographic, not just gender. However, the re-use of the instrument which has been validated with one population in a different population may require an additional re-validation. If all you are planning to do is to use the questionnaire to analyse a research question with the same sample that you used to validate it then there is no problem.
Hello Peter Samuels
Thank you so much for your insightful response. I understand. As a result, I may not be able to generalize these results to a larger population. Actually, that is not what I am looking for. I am looking to have the questions used in other researches andd populations as well. So I guess I have to add some male sample to my study.
Yes Sara Hoseingholizade , now I think you understand the principle behind the decision.
Babak Jamshidi 450 participants. 125 men (28%) and 325 women (72%)
