threats of school violence in pennsylvania after media coverage of the columbine high school Massacre examining the role of imitation
JAMA Pediatrics, 2001Co-Authors: Spencer Kostinsky, Edward O Bixler, Paul KettlAbstract:Background Following the April 20, 1999, Massacre at Columbine High School, Littleton, Colo, school administrators, law enforcement officials, and the media reported a rash of successive bomb threats and threats of school violence that were attributed to imitation. Objective To establish that the clustering of threats of school violence following the Columbine Massacre was initiated by imitation. Design A database of threats of school violence reported to the Pennsylvania Emergency Management Agency, Harrisburg, during the 50 days following the Columbine incident was examined to determine the daily frequency of threats. To determine factors that predict the occurrence of these threats, counties and school districts in which threats occurred were noted. Results Pennsylvania school districts reported 354 threats of school violence during the 50 days after the Columbine Massacre, far exceeding the 1 or 2 threats per year estimated by school administrators before 1999. The frequency of these threats over time demonstrated a crescendo-decrescendo pattern. Fifty-six percent of the threats were made on or before day 10 after the incident, and more than one third occurred on days 8, 9, and 10. Factors that predicted the likelihood of a school's receiving a threat after the Massacre included a greater proportion of white students and larger school enrollment. Conclusions Successive threats of violence follow a publicized act of school violence. The media should recognize that imitation threats can occur and craft their stories accordingly.

adolescents expressing school Massacre threats online something to be extremely worried about
Child and Adolescent Psychiatry and Mental Health, 2012Co-Authors: Nina Lindberg, Atte Oksanen, Eila Sailas, Riittakerttu KaltialaheinoAbstract:Background: Peer groups identified through the Internet have played an important role in facilitating school shootings. The aim of the present study was to determine whether the adolescents who had expressed a school Massacre threat online differed from those who had expressed one offline. Methods: A nationwide explorative study was conducted on a group of 77 13- to 18-year-old adolescents sent for adolescent psychiatric evaluation between November 2007 and June 2009 by their general practitioners because they had threatened to carry out a school Massacre. According to the referrals and medical files, 17 adolescents expressed the threat online and 60 did so offline. Results: The adolescents who expressed their threats online were more likely to be bullied and depressed, had more often pronounced the threat with clear intention and had more often made preparations to carry out the act. In contrast, the adolescents who expressed their threats offline were more likely to have problems with impulse control and had showed delinquent behavior prior to the Massacre threats. Conclusions: The Finnish adolescents who expressed their Massacre threats online could be considered a riskier group than the group who expressed the threats offline. Further studies with larger sample sizes are needed to elucidate this important topic.
