Post traumatic growth inventory (PTGI) is an assessment tool used to measure the positive psychological changes that people go through in the aftermath of a traumatic event. The inventory is used to evaluate post-traumatic growth in terms of five domains – personal strength, appreciation of life, spiritual change, relationality, and new possibilities. This article will explain how the inventory is scored.
What is Post Traumatic Growth Inventory?
The PTGI was developed by Richard Tedeschi and Lawrence Calhoun in 1996 as a means to measure the positive changes that occur in people’s lives following a traumatic event. The inventory consists of 21 items across five domains – personal strength, appreciation of life, spiritual change, relationality, and new possibilities. It is designed to assess how people have grown following a traumatic event, and is used by mental health professionals to gain insight into the psychological adjustments that people have made since their traumatic experience.
How is Post Traumatic Growth Inventory Scored?
The PTGI is scored on a 6-point Likert scale, ranging from 1 (strongly disagree) to 6 (strongly agree). Once the participant has completed the inventory, the scores in each of the five domains are calculated by summing up the responses of the individual items. The individual domain scores are then combined to obtain the total score, which is the measure of post-traumatic growth that is used in clinical practice.
In addition to the total score, the PTGI also includes a normative comparison report which compares the individual’s scores with those of the general population. This report is helpful in determining how much a person’s post-traumatic growth is above or below average.
