>The questionnaire consisted of two main sections: The first section listed 12 common media types and participants reported the total number of hours per week they spent using each medium. In the modified version used in the present study, 10 media types were retained from [2]: Print media, television, computer-based video, music, voice calls using mobile or telephone, instant messaging, Short Messaging Service (SMS) messaging, Email, web surfing and other computer-based applications. The item ‘‘video or computer games’’ was modified to include games on mobile phones. The item ‘‘non-music audio’’ was replaced with ‘‘using social networking sites’’. The changes were made to better reflect current trends in media consumption. The second section consisted of a matrix that involved participants indicating how much they concurrently used all the other types of medium as they used a primary medium. Amount of concurrent use was indicated on a scale of 1 to 4 (1 = ‘‘Never’’, 2 = ‘‘A little of the time’’, 3 = ‘‘Some of the time’’ and 4 = ‘‘Most of the time’’). The participants’ responses were first recoded as follows: ‘‘Never’’ = 0, ‘‘A little of the time’’ = 0.33, ‘‘Some of the time’’ = 0.67 and ‘‘Most of the time’’ = 1.

This seems like a bit of a silly study to me. It would be incredibly difficult for anyone in the software sector to say they aren't multitasking considering what they consider to be multitasking. I would be willing to bet most people use some forms of that concurrently, whether it's dealing with emails while in a web meeting or listening to music while coding.
