This study attempts to tease out some of these differences through multiple analytical strategies and samples.

Then, in order to quantify mobile Facebook use, we propose a new set of survey measures to tap into more and less mobile users among the sample of people who access Facebook through multiple modes. These questions serve to validate measures of mobile Facebook use, and allow us to examine how patterns of use relate to user motivations and experiences. Findings revealed important differences between PC-only and mobile users as well as a distinct and reliable meas...
