Italian Adaptation and Confirmatory Factor Analysis of the Full and the Short Form of the Posttraumatic Growth Inventory

Abstract

This study was designed to adapt and to assess the reliability and factor structure of an Italian translation of the full and short form of the Posttraumatic Growth Inventory. A sample of 1,244 Italian adults who had experienced a range of adverse life events participated in this study. Five models of the underlying structure of the Posttraumatic Growth Inventory were tested via confirmatory factor analyses. Analyses of both the short and full form of the PTGI provided support for the original correlated five-factor structure. Multigroup confirmatory factor analysis supported the invariance of the Posttraumatic Growth Inventory across gender.
