The results are clustered across seven core themes. The authors explore (1) the heterogeneity of lone actors in terms of their sociodemographic characteristics; (2) the degree to which people within the lone actor’s social or physical space were aware of a plot developing; (3) the prevalence and forms of mental disorders within lone actor samples and how they differ from what you would expect in the general population; (4) the relationship between offline and online forms of radicalization; (5) their similarity with other forms of violent lone offenders who conduct violence in public spaces; (6) what attack planning looks like; and (7) the key role protective factors might play.","PeriodicalId":409775,"journal":{"name":"International Handbook of Threat Assessment","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128924219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since that time, a number of studies have continued to support its interrater reliability and its criterion, discriminant, and predictive validity. Among the warning behaviors, the three most validated in discriminating between attackers and nonattackers are pathway, identification, and last resort. All of the other warning behaviors—fixation, novel aggression, energy burst, leakage, and directly communicated threat—are found at various frequencies throughout all the samples tested to date, including intimate partner homicide perpetrators, school shooters, adult mass murderers, public figure attackers, and lone actor terrorists.","PeriodicalId":409775,"journal":{"name":"International Handbook of Threat Assessment","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132929314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
