Expanded version of the Posttraumatic Growth and Depreciation Inventory: Scale validation and refinement among Italian adults.

Objective: The main aim of this study was to investigate the psychometric properties of the Italian version of the newly-developed Posttraumatic Growth and Depreciation Inventory (PTGDI-X) in a heterogeneous sample of Italian adults who had experienced a traumatic event.
