Psychometric Analysis of the Haitian Creole Version of the Posttraumatic Growth Inventory (PTGI) among the 2010 Earthquake Survivors

This study investigated the psychometric properties of the Haitian Creole version of the Posttraumatic Growth Inventory (PTGI) with a sample of 256 earthquake survivors in Haiti. The results showed the PTGI to have excellent internal consistency reliability for the total scale (alpha = .93) and acceptable levels of reliability for its subscales, ranging from alpha =.72 to alpha =.78. Independent t-tests revealed no statistically significant gender differences in scores on the PTGI total scale or the subscales. These findings suggest that the Haitian Creole version of the PTGI is adequate for the assessment of Haitian adults exposed to a natural disaster.
