Psychometric Properties of the Posttraumatic Growth Inventory–Short Form Among Chilean Adults

ABSTRACT

This study evaluated the factorial structure, internal consistency, and construct validity of the Chilean version of the Posttraumatic Growth Inventory–Short Form. The participants were 1,817 Chilean adults who had experienced the 2010 earthquake in Chile or other highly stressful events. Confirmatory factorial analysis supported the correlated five-factor structure of the PTGI-SF. A multigroup confirmatory factor analysis confirmed measurement invariance across different samples. Concurrent validity was assessed by correlation. These findings suggest that the psychometric properties of the PTGI-SF are adequate to measure posttraumatic growth in the Chilean and Latin American population.
