Exploring female involvement in acts of terrorism and mass shootings: a systematic review

Abstract

Purpose The purpose of this study is to explore the current literature which assesses the incidence of completed or attempted mass shooting events in which a female party acted either alone or as an accomplice; explore the involvement of women in the planning or execution of acts of terrorism; evaluate the pathology of women involved in these acts of extreme violence; highlight any gender-specific pathological and environmental risk factors associated with the planning or completion of the mass shooting, spree killing or terrorist attack events. Design/methodology/approach Using the 27-item preferred reporting items for systematic reviews and meta-analyses guidelines (Moher et al., 2009), the present systematic review explored peer-reviewed literature published between 1908 and September 2020 using six databases [SalfordUniversityJournals@Ovid; Journals@Ovid Full Text; APA PsycArticles Full Text; APA PsycExtra; APA PsycInfo; Ovid MEDLINE(R)], in addition to conducting a grey literature search on “Google Scholar” using specific search terms, predetermined following use of the patient/population, intervention, comparison framework. Findings Findings of the review did identify several distinguishing characteristics exclusive to women allied to terror organisations; including lower levels of extremism and religious ideology, lower age of radicalisation, higher levels of education than currently hypothesized and the significance of relational affiliation with extremist causes. Despite the synthesis of descriptive characterises being achieved, data relating to female mass shooters was scant and relied upon case study review and discussion. As a result, identification of precipitating psychopathological and environmental triggers was difficult, however, there does appear to be a higher proportion of female mass shooters targeting current or previous places of employment. Research limitations/implications One of the potential limitations of this review is that some relevant studies were not identified during the search. The risk of this was minimised as much as possible by screening the reference section of relevant reviews and theoretical papers (which were identified in the search of the databases) for any potentially relevant studies that may have been missed. In addition, numerous permutations of the search criteria that were entered into the databases were also entered into “GoogleScholar”. Practical implications Current literature has highlighted that the age of radicalisation among women across both jihadi-inspired, right-wing and far-left extremist organisations are decreasing, with many new recruits being born after 1990 (Jacques and Taylor, 2012). This finding aids in identifying a target of entry to minimise the chance of radicalisation, through targeted educational training and anti-radicalisation programmes intervening in at risk groups at the correct time. However, further exploration will be necessary to identify specific risk factors prior to radicalisation in such groups. Originality/value There appears to be a large gap in literature quantitively assessing the rates of psychopathological variables among this demographic. When narrowing the lens further onto female mass shooters, empirical literature investigating even characteristic variables continues to evade the academic remit. Arguably this obstruction to the current understanding of female perpetrated violence, both in an organised terror and a mass shooter capacity, limits the ability to meaningfully evaluate whether previous models assessing risk among mass shooters is valid across genders.
