To examine psychometric properties of the Brazilian version of the Posttraumatic Growth Inventory (PTGI).
A total of 300 university students were evaluated though instruments that investigated trauma history, depression and posttraumatic symptoms, and personality traits through the Big Five model. Pearson's correlation was used to assess internal consistency, inter-item reliability and construct validity. Principal component analysis and confirmatory factor analysis were performed to investigate the factor structure of the PTGI.
Results confirmed the original five-factor structure. The results showed good internal consistency for the total scale (α = 0.91) and its subscales, ranging from α = 0.85 to α = 0.70. Also, evidence of construct and convergent validity was observed through correlations with posttraumatic and depression symptoms and personality measures.
These preliminary results suggest that the Brazilian PTGI is reliable and showed adequate evidence of validity.
检验巴西版创伤后成长问卷（PTGI）的心理测量特性。
通过调查创伤史、抑郁和创伤后症状的工具以及基于大五人格模型的人格特质工具，对300名大学生进行评估。采用Pearson相关性分析来评估内部一致性、项目间信度和结构效度。进行主成分分析和验证性因素分析以探究PTGI的因素结构。
结果证实了原始的五因素结构。结果显示总量表（α = 0.91）及其分量表具有良好的内部一致性，范围从α = 0.85至α = 0.70。此外，通过与创伤后症状、抑郁症状及人格测量的相关性，观察到了结构效度和聚合效度的证据。
这些初步结果表明巴西版PTGI可靠且有充分的效度证据。
