The paper outlines various approaches to measurement, focusing mainly on those which have figured prominently in major existing studies of children's media use. We identify issues related to each technique, including advantages and disadvantages. We also include a review of existing empirical comparisons of various methodologies. The paper is intended to foster discussion of the best ways to further research and knowledge regarding the impact of media on children.
