For the purpose of my study, if I add open-ended questions to the scale, would that be considered a mixed-methods design? Also, how should go about with the analysis of the responses received on the open-ended questions listed? My study is mainly quantitative and has use of correlation, t-test and regression tests. However, as per the results obtained on my pilot study, there is a need to modify the scale and add a few open-ended questions. Your response would be highly appreciated. Thank you!
