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.

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.

Abstract Background Posttraumatic growth is one of the most commonly used concepts to evaluate positive changes after trauma. The principal scales used internationally to evaluate this phenomenon have not yet a Brazilian Portuguese version. Objectives This study aimed to translate and adapt to the Brazilian context the Posttraumatic Growth Inventory (PTGI), the Core Beliefs Inventory (CBI), and the Event Related Rumination Inventory (ERRI). Methods The procedures included translation, back translation, expert committee’s evaluation, and pilot testing in the target population. Results All items of all three instruments had a good content validity index after evaluation by four experts and three reformulations. The back translation of the final version also demonstrated that all Brazilian Portuguese versions convey the same meaning as the original English version. The final version was pilot tested with 30 undergraduate students, and all the items were above the cut-off point. Discussion This study was able to produce Brazilian versions of the PTGI, CBI, and ERRI. Further studies are underway to determine the reliability, factorial validity, and convergent validity of the subscales of the instruments.

Abstract Recent investigations propose that cognitive characteristics of autobiographical memory significantly interact with Posttraumatic Stress Disorder (PTSD). A traumatic event becoming more or less central in a person’s identity and life story might influence development of the disorder. Studies show high correlations between event centrality (EC) and PTSD. Participated in this study 68 treatment-seeking individuals referred to a specialized service for suspected trauma-related disorder: 39 matched criteria for PTSD and 29 were exposed to trauma without PTSD. Our aims were to explore how the groups differ regarding EC, depression, anxiety, posttraumatic cognitions, PTSD symptom severity, and peritraumatic dissociative experience; and how distinctively EC interacts with the measures in each group. The PTSD group had higher scores in all variables but dissociation. EC correlated with overall PTSD symptoms only in the PTSD group and with dissociation only in the no-PTSD group. Findings support a model emphasizing the role of memory processes in PTSD. People exposed to trauma who developed PTSD had the memory of the traumatic experience more intensively governing their sense of self and thus eliciting more negative cognitive reactions. As EC facilitates recollection of the traumatic event, it could also mediate a semantization process that reinforces and increases posttraumatic symptoms.

Introdução: Eventos traumáticos são fator de risco para o desenvolvimento de transtornos mentais, especialmente o transtorno do estresse pós-traumático. As avaliações que a criança faz do evento traumático podem ter um papel importante no desenvolvimento ou manutenção desse transtorno, e as respostas subjetivas dadas pela criança devem ser avaliadas para que se possa entender o impacto de tal evento em sua vida. Este estudo traduziu e adaptou o Child Posttraumatic Cognitions Inventory (cPTCI) para uso em contextos linguísticos e culturais brasileiros.Método: Os procedimentos incluíram a tradução, retrotradução, avaliação por especialista em linguística e avaliação por uma comissão de especialistas.Resultados: Os resultados do índice de validade de conteúdo foram bons para todas as dimensões após a avaliação de dois especialistas e uma reformulação. A retrotradução da versão final também demonstrou que a versão em português brasileiro do cPTCI manteve os mesmos significados da versão original em inglês. A versão final foi testada na população alvo, e todos os itens ficaram acima do ponto de corte (mínimo = 3,6; máximo = 4,0).Conclusões: Este estudo produziu uma versão brasileira do cPTCI. A confiabilidade, a validade fatorial e validade concorrente das subescalas do cPTCI estão sendo avaliadas por estudos em desenvolvimento.

Introduction: Experiencing a traumatic event is a risk factor for the development of mental illness, especially posttraumatic stress disorder. A child's appraisals of a traumatic event may play a prominent role in the development or maintenance of the disorder. Therefore, subjective responses should be evaluated to understand the impact of a traumatic event on a child's life. This study translated and adapted the Child Posttraumatic Cognitions Inventory (cPTCI) for use in linguistic and cultural contexts in Brazil.Methods: The process included translation, back-translation, language expert evaluation and expert committee's evaluation.Results: Content validity index scores were good for all dimensions after evaluation by two judges and one reformulation. The back-translation of the final version also showed that the cPTCI items in Brazilian Portuguese maintained the same meanings of the original in English. This version was tested in a sample of the target population, and all the items were above the cut-off point (minimum = 3.6; maximum = 4.0).Conclusions: This study was successful in producing a Brazilian version of the cPTCI. Further studies are underway to examine the reliability and the factorial and concurrent validity of cPTCI subscales.
