Prevention of homicidal violence in schools in Germany: The Berlin Leaking Project and the Networks Against School Shootings Project (NETWASS)

Since 1999, Germany has experienced at least twelve serious cases of targeted school violence. This article describes two projects designed to fill the gap between universal prevention and emergency response in preventing severe forms of school violence in Germany. The Berlin Leaking Project examined the viability of preventive efforts based on early identification of leaking behavior that often precedes targeted school attacks. Leaking refers to any behavior or communication that indicates a student is preparing to carry out a violent attack. This would include explicit or implied threats of violence, apparent fascination with prior acts of violence such as Columbine, and any evidence of planning or preparation to carry out an attack. The NETWASS project will test a training program and intervention strategy based on those findings, examining the usefulness of a threat assessment approach to prevent violence by training teachers to recognize leaking behavior by students. This approach is extended by training teachers on a larger scale to identify leaking and then having a school-based team evaluate the student and initiate appropriate interventions, such as mental health services, and in some cases, law enforcement action.

Student homicidal violence in schools: An international problem

School homicides have been become a worldwide phenomenon. In the decade following the Columbine shooting there have been at least forty similar events in other countries. This article addresses the international scope of this problem and some of the complex conceptual issues that make student homicidal violence difficult to define and study. Meaningful research on risk and protective factors that can inform evidence-based preventive models is summarized.

Justice and rejection sensitivity in children and adolescents with ADHD symptoms

Justice sensitivity captures individual differences in the frequency with which injustice is perceived and the intensity of emotional, cognitive, and behavioral reactions to it. Persons with ADHD have been reported to show high justice sensitivity, and a recent study provided evidence for this notion in an adult sample. In 1,235 German 10-to 19-year olds, we measured ADHD symptoms, justice sensitivity from the victim, observer, and perpetrator perspective, the frequency of perceptions of injustice, anxious and angry rejection sensitivity, depressive symptoms, conduct problems, and self-esteem. Participants with ADHD symptoms reported significantly higher victim justice sensitivity, more perceptions of injustice, and higher anxious and angry rejection sensitivity, but significantly lower perpetrator justice sensitivity than controls. In latent path analyses, justice sensitivity as well as rejection sensitivity partially mediated the link between ADHD symptoms and comorbid problems when considered simultaneously. Thus, both justice sensitivity and rejection sensitivity may contribute to explaining the emergence and maintenance of problems typically associated with ADHD symptoms, and should therefore be considered in ADHD therapy.

Links of justice and rejection sensitivity with aggression in childhood and adolescence

Individual differences in justice sensitivity and rejection sensitivity have been linked to differences in aggressive behavior in adults. However, there is little research studying this association in children and adolescents and considering the two constructs in combination. We assessed justice sensitivity from the victim, observer, and perpetrator perspective as well as anxious and angry rejection sensitivity and linked both constructs to different forms (physical, relational), and functions (proactive, reactive) of self-reported aggression and to teacher- and parent-rated aggression in N = 1,489 9- to 19-year olds in Germany. Victim sensitivity and both angry and anxious rejection sensitivity showed positive correlations with all forms and functions of aggression. Angry rejection sensitivity also correlated positively with teacher-rated aggression. Perpetrator sensitivity was negatively correlated with all aggression measures, and observer sensitivity also correlated negatively with all aggression measures except for a positive correlation with reactive aggression. Path models considering the sensitivity facets in combination and controlling for age and gender showed that higher victim justice sensitivity predicted higher aggression on all measures. Higher perpetrator sensitivity predicted lower physical, relational, proactive, and reactive aggression. Higher observer sensitivity predicted lower teacher-rated aggression. Angry rejection sensitivity predicted higher proactive and reactive aggression, whereas anxious rejection sensitivity did not make an additional contribution to the prediction of aggression. The findings are discussed in terms of social information processing models of aggression in childhood and adolescence.

International Perspectives on Prevention and Intervention in School Shootings

During the last decade, school shootings throughout the world have established the need for preventive measures, especially in North America and Europe where most cases occurred. Prevention strategies should base on scientific research that recognizes the difficulties of identifying reliable warning signs and risk factors for a low base rate phenomenon. Universal preventive measures aim to reduce risk in unselected populations (e.g., reduce bullying); indicated prevention measures use more immediate indicators, such as threats of violence and leaking, to identify persons at risk of committing an offense (i.e., threat assessment). Even with good prevention programs in place, schools need crisis response plans enabling them to react quickly and minimize harm in the event of a violent attack (i.e., limiting access to schools). We identify general difficulties of preventing school shootings and review different prevention and intervention strategies, highlighting some of the most promising approaches in the United States and Germany.

Leaking and death-threats by students: A study in German schools:

Leaking comprises observable behavior or statements that signal intentions of committing a violent offense and is considered an important warning sign for school shootings. School staff who are confronted with leaking have to assess its seriousness and react appropriately – a difficult task, because knowledge about leaking is sparse. The present study, therefore, examined how frequently leaking occurs in schools and how teachers identify leaking and respond to it. To achieve this aim, we informed teachers from eight schools in Germany about the definition of leaking and other warning signs and risk factors for school shootings in a one-hour information session. Teachers were then asked to report cases of leaking over a six- to nine-month period and to answer a questionnaire on leaking and its treatment after the information session and six to nine months later. Our results suggest that leaking is a relevant problem in German schools. Teachers mostly rated the information session positively and benefited in several aspects (e.g. reported more perceived courses of action or improved knowledge about leaking), but also expressed a constant need for support. Our findings highlight teachers’ needs for further support and training and may be used in the planning of prevention measures for school shootings.

Mutual long-term effects of school bullying, victimization, and justice sensitivity in adolescents.

In the present study, we investigate long-term relations between experiences of aggression at school and the development of justice sensitivity as a personality disposition in adolescents. We assessed justice sensitivity (from the victim, observer, and perpetrator perspective), bullying, and victimization among 565 German 12- to 18-year-olds in a one-year longitudinal study with two measurement points. Latent path analyses revealed gender differences in long-term effects of bullying and victimization on observer sensitivity and victim sensitivity. Experiences of victimization at T1 predicted an increase in victim sensitivity among girls and a decrease in victim sensitivity among boys. Bullying behavior at T1 predicted an increase in victim sensitivity among boys and a decrease in observer sensitivity among girls. We did not find long-term effects of justice sensitivity on bullying and victimization. Our findings indicate that experiences of bullying and victimization have gender-specific influences on the development of moral personality dispositions in adolescents.

Kill one or kill them all? Differences between single and multiple victim school attacks

Research indicates individual pathways towards school attacks and inconsistent offender profiles. Thus, several authors have classified offenders according to mental disorders, motives, or number/kinds of victims. We assumed differences between single and multiple victim offenders (intending to kill one or more than one victim). In qualitative and quantitative analyses of data from qualitative content analyses of case files on seven school attacks in Germany, we found differences between the offender groups in seriousness, patterns, characteristics, and classes of leaking (announcements of offences), offence-related behaviour, and offence characteristics. There were only minor differences in risk factors. Our research thus adds to the understanding of school attacks and leaking. Differences between offender groups require consideration in the planning of effective preventive approaches.

Peer and Teacher Relationships in German School Shooters

rejection, and social exclusion are often considered key contributing factors in school shootings, but recent studies have questioned their importance. One weakness in the previous research is its almost exclusive focus on U.S. American perpetrators. Therefore, we examined files of inquiry pertaining to seven school shootings in Germany that occurred between 1999 and 2006, with special attention to information on peer and teacher relationships. At the time of the offense, all perpetrators but one had a number of friends and acquaintances and were by no means socially isolated. Most, however, showed changes in their friendship patterns and had problems with some peers. In only three cases was there evidence of single bullying incidents. All perpetrators had problems with teachers prior to the offense. Our findings question that the results from previous research also apply to other samples. Problems with teachers represent an important risk factor which has been neglected in the research so far. Changes in friendship patterns may likewise constitute a warning sign. Our findings require consideration when developing prevention and intervention measures.

Media Consumption in German School Shooters

Purpose – The consumption of violent media contents has been discussed as a risk factor for school shootings repeatedly. The results of research on U.S.-American offenders support this notion. However, to date only little is known about the extent to which these findings may be transferred and generalized to perpetrators from other countries. Method – We analyzed the case files on seven school shootings perpetrated in Germany between 1999 and 2006. Findings – In five cases, detailed qualitative content analyses revealed a marked interest in media violence during the years prior to the offense. In some cases, the media consumption slowly replaced other leisure activities, focussed on topics related to the offenses as killing sprees or former school shootings, and was partly described as being addictive. One offender even utilized the media for his own purposes in order to present himself postmortem. However, two perpetrators did not show any peculiar interest in media violence. Practical and social implications – Violent media consumption is no necessary condition for school shootings, but seems to promote the development toward an offense under certain circumstances. Therefore, intensive media consumption, especially if thematically related to an offense, should be taken seriously and considered in prevention and intervention efforts. Originality/value of chapter – The findings add to the literature on risk factors for school shootings with regard to violent media consumption. The subject is analyzed in detail in a sample of German offenders, thereby widening the scope of analyzed school shootings.
