Abstract

Abstract Objective: To examine psychometric properties of the Brazilian version of the Posttraumatic Growth Inventory (PTGI). Method: 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: 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. Conclusions: These preliminary results suggest that the Brazilian PTGI is reliable and showed adequate evidence of validity.

Resumo

Resumo Objetivo: O objetivo deste estudo é examinar as propriedades psicométricas da versão brasileira do Inventário de Crescimento Pós-Traumático (Posttraumatic Growth Inventory - PTGI). Método: Foram avaliados 300 estudantes universitários através de instrumentos que investigaram histórico de trauma, sintomas pós-traumáticos e de depressão e traços de personalidade através do modelo Big Five. A correlação de Pearson foi utilizada para investigar consistência interna, confiabilidade entre itens e procedimentos de validade de construto. Análise de componentes principais e análise de fatores confirmatórios foram realizadas para investigar a estrutura fatorial do PTGI. Resultados: Os resultados confirmaram a estrutura original de cinco fatores. Os resultados mostraram boa consistência interna para a escala total (α = 0.91) e suas subescalas, variando de α = 0.85 a α = 0.70. Além disso, evidências de validade de construto e convergente foram observadas através de correlações com sintomas pós-traumáticos e de depressão e medidas de personalidade. Conclusões: Os resultados preliminares sugerem que o PTGI brasileiro é confiável e apresentou evidência de validade adequada.
