Michael Rich, MD, MPH


Michael Rich, MD, MPH is an Assistant Professor of Pediatrics at Harvard Medical School, Assistant Professor in Society, Human Development and Health at the Harvard School of Public Health, and practices adolescent medicine at Children’s Hospital Boston. He is the founder and Director of the Center on Media and Child Health at Children’s Hospital Boston, which is committed to pursuing research, developing interventions on negative health effects of media, and creating and advising on production of health-positive media.

Dr. Rich came to medicine after a twelve-year career as a filmmaker (including serving as assistant director to Akira Kurosawa on Kagemusha); his current areas of health research and clinical work bring together his experience and expertise in medicine and media. He has investigated and published on the status of media education in pediatric and child psychiatry residency programs and has performed content analyses of music videos, studying them for portrayals of violence, weapon-carrying, and substance use. His primary research uses media tools to investigate child and adolescent health. Video Intervention/Prevention Assessment (VIA), for which Dr. Rich was honored by the Society for Adolescent Medicine with their New Investigator Award, explores the illness experience through patient-created “video diaries.”

A member of the American Academy of Pediatrics (AAP) Committee on Public Education, Dr. Rich has authored or co-authored four policy statements on media and child health for the AAP and has written and presented testimony on media and child health to a variety of legislative bodies ranging from the Chicago City Council to U.S. Congress. Cognizant of the potency of the image and of the primacy of mass media as a source of information and influence, Dr. Rich studies media as a force that powerfully affects child health and health behavior and uses it as a tool for medical research, education, health care policy, and patient advocacy.

Donald F. Roberts, Ph.D.

Donald F. Roberts is the Thomas More Storke Professor in Communication at Stanford University, where he has taught and conducted research on children and media since 1968. He began his career examining the impact of television violence on children’s behavior for the first U.S. Surgeon General’s Report on Television and Social Behavior. Over the ensuing years, he has examined such issues as, the influence of media exposure on children’s and adolescents’ beliefs and behavior in such areas as violence, pro-social behavior, school performance, political attitudes, and consumer knowledge and attitudes. His most recent books include an examination of the role of popular music in the lives of adolescents (It’s NOT Only Rock and Roll) and a large-scale, national survey of U.S. youths’ media behavior (Kids and Media in America; Patterns of Use at the Millennium).

Roberts’ study of young people’s media use reports the only national, random sample survey of U.S. children’s and adolescents’ use of all of the various media conducted in at least the past 30 years. It provides a comprehensive look at how media-saturated young people’s lives have become, and is the first to examine young people’s overall media budgets, to clearly document the “ghettoization” of their media use, and to describe distinctly different types of young media users, providing provides perhaps the most detailed map of U.S. young people’s media behavior ever assembled.
