One in three children is affected by bullying in U.S. schools today, and this epidemic presents immense health, economic and societal consequences. Recognizing the need for a multi-faceted public health approach to the problem, the Highmark Foundation launched the Bullying Prevention Institute to enable implementation of the Olweus Bullying Prevention Program (OBPP) in more than 240 schools across the Foundation’s Pennsylvania service region. This webinar shared how the Foundation spearheaded the creation of a coalition of experts to implement OBPP in the largest statewide bullying prevention initiative in the country and how other stakeholders around the country can replicate this unique, model program. We discussed new cost-benefit-analysis data along with the positive results of Highmark’s efforts to create safer school climates and healthier, happier children.
