Abstract

CAAMANO W, Liliana et al. Assessment of the impact of event scale revised for post traumatic stress disorder in Chilean subjects. Rev. méd. Chile [online]. 2011, vol.139, n.9, pp.1163-1168. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872011000900008.

Background: Impact of Event Scale Revised (IES-R), that evaluates the subjective perception of stress, is used to assess post traumatic stress disorder simptoms. Aim: To adapt and validate IES-R to the Chilean population. Material and Methods: Two hundred seventy eight subjects exposed to stressful life events of varying magnitude were assessed using the IES-R, the Beck Depression Inventory, the anxiety and somatoform subscales of the Depressive, Anxiety and Somatoform Disorders Scale and the AUDIT Questionnaire. Results: IES-R had adequate psychometric properties in terms of internal consistency, test-retest reliability, convergent and discriminating validity. It identified a principal factor, explaining 67% of the variance. Conclusions: The IES-R can be used in the Chilean population to assess the degree of suffering produced by a traumatic event.
