Implications of self-report error for mobile communication research: Comparative study of Japan and the US
Research concerning the social and psychological effects of mobile phone communication is primarily conducted using self-report survey measures. However, recent studies have indicated a significant amount of measurement error when mobile phone communication is measured using self-report questions. This study compares the frequency of mobile phone use measured by self-report questions and error-free log data automatically collected through an Android smartphone application. The extent of measurement error in self-report questions and its predictors are also investigated. The data were collected from a sample of 310 Android phone users residing in Japan and 232 users from the U.S. Our descriptive analysis shows that users generally over-report their frequency of mobile communication in self-report measures. We further show an example of how this over-reporting can be responsible for inaccurate findings in the mediated communication literature. Finally, the importance of behaviour log data in mediated communication research is discussed.
