[Assessment of the impact of event scale revised for post traumatic stress disorder in Chilean subjects].
BACKGROUND
Impact of Event Scale Revised (IES-R), that evaluates the subjective perception of stress, is used to assess post traumatic stress disorder simptoms.


OBJECTIVE
To adapt and validate IES-R to the Chilean population.


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.
