Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: The device used to ansr b surveys should be taken into account.Similar levels of interitem correlations are found in PCs and smartphones.Longer completion times are found for grid questions for smartphone respondents.Sometimes less non-differentiation is observed for PCs.Using item-by-item format for all devices is a way to improve comparability. Some respondents already complete b surveys via mobile devices. These devices vary at several levels from PCs. In particular,  expect differences when grid questions are used due to the lor visibility on mobile devices and because in questionnaires optimized to be completed through smartphones, grids are split up into an item-by-item format. reports the results of a two-wave experiment conducted in Spain in 2015, comparing three groups: PCs, smartphones not-optimized, or smartphones optimized. found similar levels of interitem correlations, longer completion times for grid questions for smartphone respondents, and sometimes less non-differentiation for PCs. Thus, using the item-by-item format for smartphones and PCs seems the most appropriate way to improve comparability.
