The COVID-19 pandemic has become one of the most impactful life events in recent human experience. This study examined the psychometric properties of a version of the Impact of Event Scale, a measure of subjective suffering related to stressful life events, adapted ad hoc to the pandemic context. A total of 318 residents of Rio de Janeiro / RJ took part in the study, and were randomly divided into two samples. The scores of the first group were submitted to Exploratory Factor Analysis, which extracted a solution of two factors: Intrusive Thoughts and Avoidant Thoughts. In the second, a model of two oblique factors was tested, through Confirmatory Factor Analysis, which presented a good fit to the data, evidence of convergent validity, discriminative validity and internal consistency for the two dimensions of the scale. Regression Analysis indicated the IES's Intrusive Thoughts as the main predictor of Negative Affectivity, providing evidence of criterion validity. Sufficient evidence of validity and reliability was found for the IES adapted to the context of COVID-19.

Keywords : traumatic event; test validity; COVID-19.
