In the May issue of Obesity Reviews, Bryant et al have written a systematic review of studies related to overweight in children which included a measurement of television viewing. The authors found that most of these studies used a self-report survey to measure the hours of television watched. Few studies used a method of direct observation and reliability was often not examined. Bryant et al suggest that in the future, measurements of television viewing should be matched specifically to the research questions and study designs at hand.
Dr. Michael Rich and Dr. David Bickham of CMCH have been pilot testing a new process for measurement called MYME, which stands for Measuring Youth Media Exposure. This method combines a recall questionnaire and time-use diary with momentary sampling in the form of electronic reports and video surveys to create a powerful measurement of media use and exposure.
"After one week of pilot testing MYME, it became clear that the most complete and accurate portrait of media exposure comes through combining and cross-validating all four methods. For example, when diaries did not mention TV exposure, both momentary sampling methods showed TV to be on almost two thirds of the time. The multi-pronged approach captured not only the duration and content of media exposure, but also the context, how much attention was paid, salience or importance to the viewer/listener, and emotional state at the time of exposure." — quoted from Press Release
