Internal Consistency, Test-Retest Reliability and Sex Differences on the Posttraumatic Growth Inventory in an Australian Sample with Trauma

Abstract

The Posttraumatic Growth Inventory is designed to measure positive changes that can emerge after traumatic experiences. This study established that the high internal consistency and sound test-retest reliability of the inventory can be generalised from U.S. college students to an Australian sample drawn from the general community who had experienced major traumatic events. Interestingly, the 75 women endorsed more positive change overall than the 54 men, confirming earlier findings. However, there was no sex difference on items reflecting the perception of new possibilities in life.
