Just like all types of media use, mobile media use is usually measured using retrospective, self-reported indications of quantity in the form of duration and frequency. This is not only problematic due to the fact that people misjudge their own use to a great extent, but also because theoretical approaches predominantly suggest that mere contact is not sufficient for the description of media use. This especially holds for mobile media use, as specific contact episodes are not easily distinguishable anymore due to their short duration and high frequency. Mobile media use is rather characterized by circumstances surrounding the contact itself - they are used for countless purposes, in a habitual manner, and in various situations. In this paper, I am proposing a renewed, multidimensional measure of mobile media use that takes into account these characteristics in addition to well-known measures of quantity and suggest methods for assessing its convergent and content validity.
