Background: The "copycat effect" is a psychological phenomenon in which a person's actions influence the behavior of others, leading to imitations of behaviors, events, or ideas. It is often observed in contexts such as crimes, suicides, or violent behaviors, where media coverage of an event can trigger similar reactions in other people. Usually, many studies associate the copycat phenomenon with homicide or serial crimes. Little attention is paid to the phenomenon of emulation in suicide and, therefore, to the copycat phenomenon in this context. Methods: In our study, a systematic review of the literature was carried out using keywords related to copycat and suicide. Subsequently, each study was read and analyzed. Results: The results were compared with each other and demonstrated how it is essential to mitigate the resonance of suicidal events, especially through the media and social networks. In particular, this risk of emulation is greater among young people who are exposed to a continuous external source of information through news from the web in an incessant and constant way. This risk increases most immediately after the publicity of the suicidal event in a limited period of time. Conclusions: Unfortunately, little attention is given to the analysis of the copycat phenomenon, which causes an underestimation of the data related to suicide emulation, especially from the preventive perspective of a phenomenon that is still widespread.
