<p>Dear editors of the Interamerican Journal of Psychology,</p>
<p>&nbsp;As you may know, currently México is clasified as one of the most violent and dangerous countries in the world. This is not a recent problem, but from several years. The amount of crimes that vary from raping, homicides, robbery, among several more of the dangers that the Mexican population has to endure in the everyday life. Therefore, the number of people suffering from Posttraumatic Stress Disorder (PTSD) is expected to be high, and therefore it is also expected to have several studies being conducted in México in order to treat these patients. Therefore the objective of the manuscript: “<em>A systematic review of Criminal Violence, PTSD and current Treatment Efforts in Mexico</em>” has as objective to provide to the reader what are the main research’s that were implemented in México after the last review analyzing the PTSD, that was conducted in 2005. This review was adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Therefore the method is clearly described and the results are explained in detail.</p>
<p>Contrary to what was expected, the amount of research regarding PTSD is scarce. This is a serious issue due to the high number of people suffering from this disorder and not obtaining psychological support based on the most scientific evidence, or at least not being reported.</p>
<p>We, the authors, hope that this article fits to the objective of your journal, and that the readers around the globe can get benefit from this review in order to urge the development of psychological therapies based in evidence, to help the Mexican and Latin American population with similar issues happening as can be perhaps Colombia.</p>
<p>&nbsp;</p>
<p>My best regard,</p>
