詰め込みすぎにご用心―モバイル端末と複数呈示形式がデータの質を低下させる可能性の検討―

抄録

With the expansion of psychological studies conducted online, researchers show greater interest in the quality of the data collected from online studies. Factors that may compromise the data quality include lack of control of environmental variables, nonnaïveté due to repeated participation, and reduced attention to the study materials. In this study, we examined the possibility that type of device and the presentation format of study materials may compromise the quality of responses. An online study with a total of 1,005 crowd-workers (PC=485, mobile=520) revealed that mobile devices were associated with less attentive responses. Results also showed that mobile devices tended to elicit relatively inconsistent responses to psychological scales, specifically when combined with the multiple presentation formats, in which all items of the scale were presented at once. The results suggest that the importance of considering the type of device and the format of information presentation in the future studies conducted online. Future research in this domain should further address factors that may lower the quality of data, such as demographics.
