The ability to accurately predict the risk of an individual committing an act of targeted violence is likely to be impossible given the low base rate of these acts (Goodwill & Meloy, 2019). Nevertheless, prevention is possible if there is a focus on fact-based behaviors, and threat management is in place. The Terrorist Radicalization Assessment Protocol (TRAP-18; Meloy et al., 2015; Meloy & Gill, 2016; Meloy, Habermeyer, & Guldimann, 2015; Meloy, 2017) is a collection of 18 behavior-based warning signs for terror incidents. There are eight proximal characteristics and ten distal characteristics. The aim of this review was to identify studies which have utilized the TRAP-18 either prospectively (operational use) or retroactively or studies which have investigated the validity and reliability of the TRAP-18. A total of 17 relevant papers were identified in the review including six case studies and eleven empirical papers.
