Adaptación de la Lista Checable de Trastorno por Estrés Postraumático para DSM-5 en Población Mexicana

The Posttraumatic Stress Disorder Checklist (PCL) has been one of the most applied scales in the clinical field, which has been recently adapted to the DSM-5 criteria (PCL-5). Considering the problems posed by PTSD in the population and the recent changes proposed in the DSM-5, it is important to have validated scales in Mexican population based on the new diagnostic criteria described. The present work describes the psychometric properties for the validation in Mexican population of the PCL-5, where 204 students from open and distance learning university between 18 and 59 years old participated, recruited through a virtual platform. The results showed an adequate internal consistency (.97), as well as an appropriate convergent validity (rs=.58 to .88). At the same time, different exploratory and confirmatory factor analyses  were conducted, where appropriate adjustments to the models proposed in the DSM-5 and previous studies of the original scale were obtained. We conclude that the scale is valid and reliable in the Mexican population, which makes it the only instrument adapted to the DSM-5 for the evaluation of PTSD in this context. However, additional studies with greater control over different types of trauma are recommended for a  better description of the construct.
