Dr. Horn joined GWSPH in June 2012 as the School’s first Associate Dean of Research. She arrived from West Virginia University where she was the Associate Director of Population Health Research at the Mary Babb Randolph Cancer Center and a Robert C. Byrd Professor of Community Medicine. Dean Horn has diverse research funding portfolio history from federal, state, and private agencies. Over a decade of continuous federal funding has afforded her the opportunity to develop an internationally recognized program of research in teen smoking cessation. A significant part of that program is the Not On Tobacco (N-O-T) teen smoking cessation program, which she co-developed during her time at West Virginia University. N-O-T was formally adopted by the American Lung Association (ALA) in 1998. N-O-T is a multi-session, group-based, gender-tailored intervention, most frequently implemented in school-based settings by ALA-certified facilitators. A recent National Survey of Tobacco Cessation Programs for Youths by Curry and colleagues (2007) cited N-O-T as the most widely used teen cessation program in the US. Curry’s study profiled 591 programs in 408 US counties. Demonstrating national reach, the study found that N-O-T was the most commonly used packaged program and was reported as the source program by 30% of school administrators. N-O-T has been evaluated by the National Registry of Effective Programs and has received several awards. In recent years, it was federally recognized as a Substance Abuse and Mental Health Administration evidence-based Model Program, a National Cancer Institute Research Tested Intervention Program, Centers for Disease Control and Prevention Adoptable Program, and an Office of Juvenile Justice and Delinquency Prevention Model Program. In 2004, Horn received the Award of Research Innovation for N-O-T from the Centers for Disease Control and Prevention, National Center for Chronic Disease Prevention and Health Promotion, Prevention Research Centers. In 2005, Horn received the Dean’s Award of Research Excellence from the West Virginia University School of Medicine. In 2008, the CDC launched the N-O-T web portal (http://www.notontobacco.com) to enhance program reach and to establish a new and innovative venue for dissemination research. An ALA assessment between 2000-2009 projected that N-O-T reached over 300,000 teen smokers doubling teens’ chances of quitting smoking at the end of the program. Dr. Horn also led the development of an American Indian N-O-T adaptation and a self-paced, Internet-based N-O-T Power Guide. N-O-T is also available in Spanish. While N-O-T studies show positive impact on teens, Horn continues to investigate approaches to improve teens’ odds of quitting smoking. Most recently, Horn and her team published as study in Pediatrics (September 2011) and the Journal of Adolescent Health (2013) demonstrating the importance of adding physical activity to teen smoking cessation. These studies caught the attention of the popular media sounding in media venues around the world, including TIME, CNN, USAToday, and the NY Times. Dr. Horn continues to grow her tobacco control research portfolio at the GWSPH partnering not only with GW colleagues, but also with other major universities and organizations across the District. Her continued impact on the field is evidence by her recently received awarded R01 from the National Cancer Institute to study the social and environmental influences of teen smoking cessation.
