ABSTRACT

O Inventário de Crescimento Pós-Traumático (PTGI) é um instrumento de autorrelato que avalia mudanças positivas provenientes do enfrentamento de situações adversas. O presente estudo investigou a estrutura fatorial da versão brasileira do instrumento (PTGI-B). Participaram da pesquisa 321 pessoas que passaram por situações adversas variadas. Por meio do método de análise fatorial confirmatória, testou-se cinco diferentes modelos de estrutura fatorial. A estrutura convencional de cinco fatores foi a que melhor se adequou aos dados. No entanto, a estrutura hierárquica de cinco fatores de primeira ordem organizados em torno de um fator geral de segunda também apresentou índices de ajuste adequados. O estudo replica a estrutura fatorial original do PTGI (relacionamento com os outros, novas possibilidades, força pessoal, apreciação pela vida e mudança espiritual). Além disso, os resultados indicam que as análises com o PTGI-B podem ser realizadas tanto considerando as subdimensões do instrumento, quanto uma dimensão geral de crescimento pós-traumático. (AU)


The Posttraumatic Growth Inventory (PTGI) is a self-report instrument used to evaluate positive changes arising from coping with adversity. The current study aimed to investigate the factor structure of the Brazilian version of the instrument (PTGI-Br). A total of 321 subjects, who had experienced a variety of adverse events, participated in the study. Five different factor structure models of the PTGI-Br were tested through the confirmatory factor analysis method. The conventional five-factor model (relating to others, new possibilities, personal strength, appreciation of life and spiritual change) showed better fit indexes when compared to the other models. The factor structure of five first order factors organized around a global hi-order factor was also adequate. The result replicates the PTGI original structure. In addition, it allows the five dimensions of the PTGI-Br, as well as the global higher order dimension, to be used in statistical analysis. (AU)

ABSTRACT

O crescimento pós-traumático (CPT) refere-se à mudança positiva em algum aspecto da experiência humana como resultado do enfrentamento de situações adversas. O presente trabalho investigou se as evidências de validade externa do Inventário de Crescimento PósTraumático (PTGI) são mais consistentes quando se compara os resultados de um subgrupo que pontuou alto na Escala de Centralidade de Eventos (ECE) com os de um subgrupo que pontuou baixo. A ECE avalia em que medida o evento de referência contribuiu na formação da identidade dos indivíduos. Participaram do estudo 317 indivíduos que passaram por situações adversas variadas. As correlações entre CPT e suporte social, sentido de vida, satisfação com a vida, religiosidade e desajuste psicológico apresentaram maior magnitude e coerência no subgrupo pontuou alto na ECE. Os resultados fortalecem a concepção de que apenas eventos que levam a uma reavaliação das crenças centrais dos indivíduos devem ser incluídos nos estudos de CPT.


Posttraumatic growth (PTG) is the experience of positive change that occurs as a result of facing highly challenging adverse situations. The present work investigated whether the external validity evidence of the Post Traumatic Growth Inventory (PTGI) is more consistent when considering the events in which individuals scored high on the Centrality of Events Scale (CES) versus events in which individuals scored low. The CES assesses to what extent the reference event contributed to the formation of individuals' identity. Participated in the study 317 individuals who had been through a variety of adverse events. The correlations between PTGI scores and social support, meaning in life, life satisfaction, religiosity, and psychological distress became larger and more coherent in the subgroup that scored high in ECE. The results corroborate the conception that only events that lead to a reassessment of individuals' central beliefs should be included in the PTG studies.


Crecimiento postraumático (CPT) se refiere al cambio positivo en algún aspecto de la experiencia humana como resultado del enfrentamiento de situaciones adversas. Este trabajo investigó si las evidencias de validez externa del Inventario de Crecimiento PostTraumático (PTGI) son más consistentes cuando se compara los resultados de un subgrupo punteado alto en la Escala de Centralidad de Eventos (ECE) con los de un que punteaba bajo. La ECE evalúa en qué medida el evento de referencia contribuyó en la formación de la identidad de los individuos. Participaron del estudio 317 individuos que pasaron por situaciones adversas variadas. Las correlaciones entre CPT y las demás variables de interés presentaron mayor magnitud y coherencia en el subgrupo puntuó alto en la ECE. Los resultados fortalecen la concepción de que sólo los eventos que conducen a una reevaluación de las creencias centrales deben ser incluidos en los estudios de CPT.

ABSTRACT

O presente estudo objetivou verificar os parâmetros psicométricos do Posttraumatic Growth Inventory ­ PTGI, apresentando evidências de validade fatorial, consistência interna e etapas da sua adaptação transcultural. A amostra foi composta por 205 participantes, sua maioria do sexo feminino (59,03%), com idades variando entre 18 e 86 anos (M = 29,54; DP = 11,43). Estes responderam ao PTGI, Life Stressor Checklist ­ Revised e perguntas demográficas. Nas análises fatoriais confirmatórias, observa-se o modelo pentaforial como mais adequado para o PTGI, sendo estatisticamente superior ao tri e ao unifatorial. A consistência interna de seus fatores (alfa de Cronbach) variou de 0,70 a 0,86, com alfa geral de 0,92, valores considerados aceitáveis. Conclui-se que essa medida, apresentando evidências de validade de construto, pode ser usada adequadamente em pesquisas no contexto em que foi adaptada, entretanto, recomenda-se o uso do instrumento em amostras mais heterogêneas e a realização de outras análises, observando sua invariância fatorial.(AU)


This study aimed to verify the psychometric parameters of the Posttraumatic Growth Inventory - PTGI, presenting evidence of factorial validity, internal consistency and steps of cross-cultural adaptation. The sample consisted of 205 participants from northeastern Brazilian cities, mostly female (59.03%), aged between 18 and 86 years (M = 29.5, SD = 11.4). Participants answered the PTGI, the Life Stressor Checklist ­ Revised, and demographic questions. The confirmatory factor analysis observed the penta-factorial model as more suitable for PTGI, being statistically superior to three and one-factor. The internal consistency of its factors (Cronbach's alpha) ranged from .70 to .86, with general alpha of .92, values considered acceptable. It follows that this measurement, providing evidence of construct validity, can be properly used in research in the context in which it was adapted to, however, we recommend the use of the instrument in more heterogeneous samples and conducting other analyzes, observing its factorial invariance.(AU)

ABSTRACT

Objectives: To investigate the level and determinants of posttraumatic growth in Iranian cancer patients. Materials and Methods: This descriptive-correlational design study was conducted within a university-affiliated oncology hospital in Iran. A convenience sample of 450 patients with a definitive diagnosis of cancer of any type completed a demographic questionnaire and a posttraumatic growth inventory. Some disease-related information was obtained from patients' medical records. Results: The mean of posttraumatic growth reported by participants was 76.1. There was a statistically significant association between experience of posttraumatic growth and age (r = − 0.21, P=0.001), education at university level (F = 8.9, P=0.001) and history of treatment by radiotherapy (t = 2.1, P=0.03). Conclusion: The findings of this study suggest that Iranian cancer patients experience a moderate to high level of posttraumatic growth and confirm the hypothesis that the level of posttraumatic growth in non-Western cancer patients is more than that of Western cancer patients. Although, assessing the reasons for this difference needs more investigations.

ABSTRACT

Objective: To revise the Post-traumatic Growth Inventory (PTGI) in a sample of adolescents who experienced the Wenchuan earthquake. Method: The Chinese version of PTGI together with the Children's De-pression Inventory (CDI) and Children's Revised Impact of Event Scale (CRIES) were administrated among 2 samples of the middle school students from two middle schools in Chongqing city. Result: A three-factor model of PTGI (interpersonal relationship, new possibility, and personal strength) was found in the first sample by explor-atory factor analysis and was confirmed in the second sample by confirmatory analysis. The main parameters were as follows: IFI=0.990, CFI=0.990, RMSEA =0.051, and X~2/df=3.082. The original five-factor model (IFI=0.987, CFI=0.981, RMSEA=0.053, and X~2/df=3.317) was also tested by confirmatory analysis and was found inferior to the three-factor model. The reliability of the revised scale was acceptable, with Crunbach's a coeffi-cients ranging from 0.66~0.85. The total score of PTGI and the score of sub-scales were moderately correlated with the intrusion scale in CRIES, with coefficients ranging from 0.19 to 0.27. The total score of PTGI and the score of sub-scales were negatively correlated with CDI, with coefficients ranging from-0.21 to-0.29. Conclusion: The newly revised adolescent version of PTGI demonstrates good structure validity and acceptable reliability. It may be a potentially good instrument to measure posttraumatic growth among Chinese adolescents.
