Posttraumatic growth is a phenomenon that refers to positive changes in coping with challenging life events. However, there is no short-form version of the scale measuring post-traumatic growth that has undergone a structured validity assessment in Turkish adolescents. Therefore, we aimed to adapt the Posttraumatic Growth Inventory-Short Form (PTGI-SF) to Turkish adolescents. Participants were adolescents aged 14–18 years with traumatic experiences (Mage = 15.57, SD = 1.17). This study found that the PTGI-SF construct was valid and demonstrated good model fit in Turkish adolescents. The internal consistency of the scale was calculated to be high. As measurement invariance was verified, it was found that the scale represented the same psychological structure in terms of gender. The PTGI-SF exceeded the threshold and showed sufficient convergent validity. Furthermore, item response theory revealed that the items were highly discriminant from each other. Additionally, network analysis showed that the items were strongly related to each other. In conclusion, this study has realised a unique adaptation with adequate validity and reliability to measure posttraumatic growth in Turkish adolescents.
