Eficacia de un programa de intervención basado en la exposición mediante realidad virtual en desplazados con trastorno por estrés postraumático (TEPT) en una ciudad de Colombia

The cognitive-behavioral exposure technique is supported for treating trauma-related disorders. When combined with virtual reality, it provides a controlled and safe environment for application. This study evaluated the effectiveness of a virtual reality exposure-based intervention program in resettled displaced individuals with PTSD from Montería, Colombia. A quasi-experimental design with repeated measures (pre-post and 6-month follow-up) was used. A total of 23 victims of forced displacement were randomly assigned to two groups: one with virtual reality exposure (n=11) and one with imaginative exposure (n=12). Instruments on trauma, associated symptoms, and quality of life were applied. Results show that virtual reality reduces trauma symptoms such as re-experiencing and state anxiety while improving positive beliefs and physical and psychological health. The study highlights the validity of exposure programs in addressing trauma-related symptoms in displaced populations, discussing the findings in light of existing literature.
