Validation of the short posttraumatic stress disorder rating interview (SPRINT-E) in a sample of people affected by 27-F Chilean earthquake and tsunami

Abstract

On February 27, 2010 (27-F) 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 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 27-F.

The analysis of reliability (a =. 916), concurrent validity (all items significantly correlated with the scale used as a criterion DST) and construct validity (CMIN = 3,366, RMSEA =. 090, NFI =. 918, CFI =. 940 and PNFI =. 718 for two-factor 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 Spanish-speaking population prone to natural disasters such as the Chilean F-27, the Japanese  March 11, 2011 or the spainish May 11, 2011.
