The criminal violence is attached with mental health problems as depression and substance use and abuse. However one of most important psychological problems linked with the victims of violence is Posttraumatic Stress Disorder (PSTD) and Acute Stress Disorder (ASD). In Mexico, according to the ICESI in 2012, 11% (6,800/for each 100 thousands of habitants) of the population over 18 years experienced a crime. One in four of the people victim of violence develops PSTD symptoms. Due to this socially relevant problem and based on the efficacy of Virtual Reality (VR) treatments, it is important to design treatments involving the use of VR because it can help overcome some of the limitations of traditional therapy using exposure. The present study shows preliminary results of efficacy or virtual reality treatment for PTSD and ASD for crime violence. The clinical sample was conformed for 9 participants from city of Mexico, 6 participants with PTSD diagnoses and 3 participants with ASD diagnoses, aged between 18 and 65. All participants gave informed consent to participate. Treatment was delivered in 90 min individual sessions conducted once a week. Three virtual scenarios for PTSD exposure treatment were used. Improvement was seen in measures of stress, anxiety and depression in both treatment groups, which confirms the clinical efficacious for this technique to treat stress-related disorders.
