Abstract(s)
A exposição a situações adversas, potencialmente indutoras de uma reação de stress
inadaptada, pode constituir-se como um desafio percursor de mudanças psicológicas
positivas, na esfera pessoal, relacional e espiritual. Esta mudanças positivas, resultantes do
confronto com o acontecimento traumático são denominadas por “crescimento póstraumático”.
Este estudo visa fornecer evidências empíricas através do estudo das
características psicométricas dos instrumentos, Posttraumatic Growth Inventory (PTGI); Core
Beliefs Inventory (CBI); Event Related Rumination Inventory (ERRI) e Distress Disclosure
Index (DDI). Com a presente bateria de instrumentos avalia-se as mudanças psicológicas
positivas, resultantes dos esforços empreendidos para lidar com os acontecimentos adversos
(PTGI); as mudanças das crenças centrais (CBI); o estilo de ruminação (ERRI) e a expressão
emocional (DDI). Os dados do estudo apresentado, nomeadamente a análise da estrutura
fatorial, dos índices de consistência interna e os dados relativos à validade de constructo,
foram recolhidos junto de uma amostra de 510 participantes da população geral portuguesa.
Os resultados obtidos indicam que, os quatro instrumentos analisados no presente estudo,
apresentam bons níveis de sensibilidade, fiabilidade, validade e ajustamento. A análise da
consistência interna, utilizando o coeficiente de alfa de Cronbach, revelou boa consistência
interna para a escala total, assim como para as suas dimensões, em todos os instrumentos em
estudo. Estes dados permitem concluir que recomenda-se utilização destes instrumentos tanto
para aplicação em contexto clínico como de investigação.
ABSTRACT------Exposure to adverse situations, potentially induces a maladaptative stress reaction, and can be constituted as a precursor of positive psychological changes at personal, relational and spiritual domains. These positive changes as a result from coping with trauma are known as "posttraumatic growth". This study means to provide empirical evidence, through the study of the psychometric characteristics of the instruments, Posttraumatic Growth Inventory (PTGI); Core Beliefs Inventory (CBI); Event Related Rumination Inventory (ERRI) and Distress Disclosure Index (DDI). These instruments assess the positive changes as a result of struggle with higly challenging adverse events (PTGI); challenge of core beliefs (CBI); the style of rumination (ERRI) and emotional disclosure (DDI). The results obtained from the analysis of the factor structure, the internal consistency indices and the construct validity were collected from a sample of 510 participants collected from normative Portuguese population. The results indicate that the four instruments analyzed in this study, have good levels of sensitivity, reliability, validity, and adjustment. The analysis of internal consistency using Cronbach's alpha coefficient, showed good internal consistency for the total scale, as well as its dimensions, in all instruments under study. The data shows that the use of these instruments is recommended both in the clinical setting and research.
