Conducted validation of K-PTGI using the Rasch model.
Analyzed the validity of the instrument in measuring posttraumatic growth.

K-PTGI shows strong validity overall.
Recommendations for future revisions include adjusting spiritually themed items.
Need for easier items to better reflect early posttraumatic growth.
