This literature review prim.rily aim. to explore and synthesise the previous studies in sim.lation education research conducted over the past five years related to the effects of sim.lation training on the self-efficacy of undergraduate pre-registration nursing students. The second aim.of this study is to explore additional outcom. variables that were exam.ned in the previous studies. Five electronic databases were searched system.tically. These databases were m.DLINE, CINAHL Plus, Scopus, Em.ase and PsycINFO. The PICO m.del was em.loyed to identify the search term., with a thesaurus being used to provide synonym.. Reference lists of relevant articles were exam.ned and hand searches of journals were also undertaken. The quality of each study was assessed using the Sim.lation Research Rubric (SRR). A total of 11 studies were included. All studies explored the im.act of sim.lation education on undergraduate pre-registration nursing. Six studies explored nursing students’ com.etence and perform.nce and two papers exam.ned their critical thinking. Problem.solving, learning m.tivation, com.unication skills and knowledge acquisition were exam.ned once. The m.jority of studies indicated that sim.lation training has a positive im.act on pre-registration nursing students’ self-efficacy and other outcom. variables. Furtherm.re, the study results indicate that sim.lation training is m.re dependable than traditional training, and students were extrem.ly satisfied with the sim.lation training. However, m.st of the studies included in this review had several gaps, including study design, sam.le size and dissim.larities between the scales used. Further research with large sam.les, reliable and valid instrum.nts, and outcom.s m.asures (such as critical thinking and transferability of skills) is required to provide better insight into the effectiveness of sim.lation in undergraduate nursing education. .
