Resumo
Este estudo teve como principal objetivo validar a Integration of Stressful Life Experiences Scale
(ISLES) para a população portuguesa, numa amostra de indivíduos enlutados. A ISLES avalia o
grau em que um indivíduo que vivenciou uma experiência stressante consegue integrá-la na sua
autonarrativa. Examinou-se a validade e a fiabilidade da mesma, através de uma amostra de 242
adultos portugueses. Foi realizada uma análise fatorial confirmatória e para avaliar a consistência
interna e a homogeneidade da escala foram analisados o ómega de McDonald, o alfa de Cronbach
e as correlações médias entre itens. Os resultados apoiaram uma estrutura fatorial de dois fatores
e foi possível observar um bom ajustamento local e global do modelo. Foram reunidas evidências
a favor da validade convergente e da fiabilidade da escala. Este estudo contribui para oferecer
algum suporte psicométrico inicial para a ISLES – versão portuguesa, tornando-se essencial
introduzir este tipo de instrumentos de avaliação em contexto português, de forma a aumentar a
relevância atribuída ao meaning making, dentro da comunidade e dentro dos contextos clínico e
de investigação.
The main objective of this study was to validate the Integration of Stressful Life Experiences Scale (ISLES) for the Portuguese population, in a sample of bereaved individuals. ISLES assesses the degree to which an individual who has experienced a stressful experience is able to integrate it into their self-narrative. Its validity and reliability were examined through a sample of 242 Portuguese adults. A confirmatory factor analysis was performed and to assess the internal consistency and homogeneity of the scale, McDonald's omega, Cronbach's alpha and mean correlations between items were analyzed. The results supported a factorial structure of two factors, and it was possible to observe a good local and global adjustment of the model. Evidence in favor of the convergent validity and reliability of the scale was gathered. This study contributes to providing some initial psychometric support for ISLES – Portuguese version. It is essential to introduce this type of assessment tools in the Portuguese context to increase the relevance given to meaning making, within the community, clinical and research contexts.
