The commercial media is an influential sociocultural force and transmitter of health information especially for adolescents. Instruction in critical media health literacy, a combination of concepts from critical health literacy and critical media literacy, is a potentially effective means of raising adolescents' awareness about commercial media and its influence on their health. We first provide background on critical media health literacy for adolescents. We then discuss the potential for involving adolescents in creating multimedia to demonstrate basic principles of critical media health literacy skills. Using excerpts from two of our research projects to illustrate our ideas, we draw conclusions and suggest future research in critical media health literacy for adolescents.
