Purpose: The study examined the psychometric properties of the Greek posttraumatic growth inventory (PTGI) among healthcare workers and general population during the COVID-19 pandemic. Methods: The Greek versions of the PTGI, the Brief COPE, and the Brief Resilience scale were administered to 2163 participants from the general population and 1837 healthcare workers. Results: The five-factor structure was tested separately in the two samples and presented a comparable good fit to the data. Then it was tested in the combined sample against the single-factor structure and the five-factor structure showed a slightly better fit to the data. The PTGI showed good reliability (Cronbach's alpha, composite reliability, inter-item correlations, corrected item-total correlations, and scale-total correlations), convergent validity (AVE values and interscale correlations), discriminant validity (HTMT), and concurrent validity (correlation between PTGI-Spiritual Change and COPE Religion). Discussion: The Greek version of the PTGI appears to be a psychometrically sound instrument for measuring PTG during COVID-19 among Greeks.

COVID-19 大流行期间希腊版 PTGI 的心理测量评估


目的：该研究检查了 COVID-19 大流行期间医护人员和普通人群希腊创伤后生长量表 （PTGI） 的心理测量特性。方法：对来自普通人群的 2163 名参与者和 1837 名医护人员进行了希腊语版本的 PTGI、Brief COPE 和 Brief Resilience 量表。结果： 在两个样本中分别测试了 5 因素结构，并与数据呈现出相当的良好拟合。然后在组合样本中针对单因素结构进行了测试，五因素结构与数据的拟合略好。PTGI 表现出良好的信度 （Cronbach's alpha 、 composite reliability、项目间相关性、校正的项目-总相关性和量表-总相关性）、收敛效度 （AVE 值和尺度间相关性）、判别效度 （HTMT） 和并发效度 （PTGI-Spiritual Change 和 COPE Religion 之间的相关性）。讨论：希腊语版本的 PTGI 似乎是一种在希腊人 COVID-19 期间测量 PTG 的心理测量工具。
