Description
Summary:In the study of human behavior concerning the ex-position to highly stressful events, psychology has taken a leap forward, studying not only the negative effects of such events, but also the knowledge a person may gain from them, which is known as posttraumatic growth. The aim of this study was to analyze the psychometric properties of the Posttraumatic Growth Inventory (PTGI) in a sample of 450 adult survivors of the earthquake that took place on the Ecuadorian coast in 2016. The PTGI showed high internal consistency (α = .95). The confirmatory factor analysis dis-played an appropriate adjustment for a bifactor structure consisting of three specific factors and one general factor. Furthermore, the PTGI showed a factorial invariance when comparing men and women. We could conclude that the PTGI is a reliable and internally valid instrument for the study of posttraumatic growth in Ecuadorian population.
