Measuring media multitasking Development of a short measure of media multitasking for adolescents

Although media multitasking is an increasingly occurring form of media use, there are currently no validated, short instruments to measure media multitasking among adolescents. The aim of the present study, therefore, was to develop a short media multitasking measure for adolescents (MMM-S). Two studies with a total sample of 2,278 adolescents were conducted. The findings of these studies suggest that the MMM-S is a useful, reliable, and valid measure to assess media multitasking among adolescents. The findings indicate that the concurrent validity of the short measure is equal to that of a more extensive measure. Because of its high utility, the MMM-S may provide an alternative for existing extensive measures of media multitasking.
