T1  - Narcissistic symptoms in German school shooters
T2  - Postprints der Universität Potsdam : Humanwissenschaftliche Reihe
N2  - School shooters are often described as narcissistic, but empirical evidence is scant. To provide more reliable and detailed information, we conducted an exploratory study, analyzing police investigation files on seven school shootings in Germany, looking for symptoms of narcissistic personality disorder as defined by the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) in witnesses' and offenders' reports and expert psychological evaluations. Three out of four offenders who had been treated for mental disorders prior to the offenses displayed detached symptoms of narcissism, but none was diagnosed with narcissistic personality disorder. Of the other three, two displayed narcissistic traits. In one case, the number of symptoms would have justified a diagnosis of narcissistic personality disorder. Offenders showed low and high self-esteem and a range of other mental disorders. Thus, narcissism is not a common characteristic of school shooters, but possibly more frequent than in the general population. This should be considered in developing adequate preventive and intervention measures.

BT  - differences between single and multiple victim school attacks
T2  - Postprints der Universität Potsdam : Humanwissenschaftliche Reihe
N2  - 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.
