Validación de la escala breve para diagnosticar estrés post-traumático (SPRINT-E) en una muestra de personas afectadas por el te-rremoto y tsunami del 27-F en Chile

Abstract

On February 27, 2010 (F-27) there was an earthquake and a tsunami in Chile that has caused a great impact on the mental health of the population of this country, specifically in the increase of cases of posttraumatic stress disorder (PTSD). In view of count better instruments to measure PTSD was applied for the first time since it was created, the SPRINT-E scale in a population other than the U.S., specifically in 291 people who experienced the F-27. The analysis of reliability (α=. 916), concurrent validity (all items significantly correlated with the scale used as a criterion DTS) and construct validity (CMIN=2.237, RMSEA=.092, NFI=.901, CFI=.942 and PNFI=.704 for twofactor model) indicate that SPRINT-E is a valid and reliable scale to measure PTSD in this population. Finally, some reflections about new factor structure discovered in this analysis, which is consistent with the meaning of items and with theoretical models such as covert stimuli. It also reflects on the usefulness of a brief scale, proven valid and very good psychometric characteristics in a Spanishspeaking population prone to natural disasters such as Chilean F-27, Japan (March 11, 2011) or Spain (May 11, 2011). © 2013: Servicio de Publicaciones de la Universidad de Murcia.
