The data from the K-12 School Shooting Database (K-12 SSDB) of 1,544 school shootings were used to explore patterns of mass school shootings in the United States, with particular focus on the interplay between relevant predictors of these tragic events. Through a conjunctive analysis of case configurations (CACC), results from the current study show that (1) mass school shootings are rare and cluster significantly among dominant situational profiles, defined by the unique combination of variables attributes; (2) mass school shootings are never pre-planned and in no case involve hostages. Current findings are discussed in light of existing school shooting scholarship and recommendations for policy and future areas of research are offered.

将美国的大规模学校枪击事件背景化

来自 K-12 学校枪击事件数据库 (K-12 SSDB) 的 1,544 起校园枪击事件的数据被用于探索美国大规模校园枪击事件的模式，特别关注这些悲剧事件的相关预测因素之间的相互作用。通过对案例配置 (CACC) 的联合分析，当前研究的结果表明：(1) 大规模学校枪击事件很少见，并且在主要情境中显着聚集，由变量属性的独特组合定义；(2) 大规模校园枪击事件从来都不是预先计划好的，也绝不涉及人质。根据现有的学校射击奖学金讨论了当前的发现，并提供了对政策和未来研究领域的建议。
