Details		AUTHORS' ABSTRACT: Boase and Ling 2013 (IEEE #5325) Approximately 40% of mobile phone use studies published in scholarly communication journals base their findings on self-report data about how frequently respondents use their mobile phones. Using a subset of a larger representative sample we examine the validity of this type of self-report data by comparing it to server log data. The self-report data correlate only moderately with the server log data, indicating low criterion validity. The categorical self-report measure asking respondents to estimate how often they use their mobile phones fared better than the continuous self-report measure asking them to estimate their mobile phone activity yesterday. A multivariate exploratory analysis further suggests that it may be difficult to identify under- and overreporting using demographic variables alone.
