Introdução: O luto agudo surge quando a pessoa ganha a consciência de que perdeu alguém
ou algo, importante na sua vida (Shear, 2015). É por toda a complexidade deste processo que
se torna pertinente a sua avaliação e estudo, para que se possa conduzir uma melhor intervenção
terapêutica. Este artigo tem como objetivo a realização da adaptação para a população
portuguesa e da avaliação das propriedades psicométricas do Inventário de Luto Revisto do
Texas (TRIG).
Método: Adaptação: seguindo as guidelines de Beaton e colaboradores (2000). Amostra: 440
participantes. A média de idades foi 43.16. Análise fatorial confirmatória: foram testados dois
modelos, um modelo de três fatores (sentimentos passados, sentimentos presentes, e descrença)
e um modelo de dois fatores (sentimentos passados e sentimentos presentes). Invariância entre
Multigrupos: foram testadas a configural, a métrica, a escalar e a residual. Validade convergente
e discriminante: Foi testada entre o TRIG (e subescalas) com o PG-13, e com o BDI II,
respetivamente.
Resultados: Análise Fatorial Confirmatória: O modelo que apresentou melhores resultados foi
o de dois fatores, apresentando um ajuste dentro do limite aceitável. Invariância entre
Multigrupos: Concluiu-se que existe invariância entre sexos. Consistência Interna: apresentou
resultados significativos, no TRIG total como nas suas subescalas. Validade Convergente:
correlação moderada positiva e significativa. Validade discriminante: correlação baixa e
positiva.
Conclusão: O TRIG – Versão Portuguesa apresentou bons resultados psicométricos,
demonstrando ser válido e fiável para a população portuguesa. Sugere-se que futuramente o
TRIG – Versão Portuguesa seja testado com amostras específicas.
ABSTRACT: Introduction: Acute grief arises when a person becomes aware that he/she has lost someone or something important in his/her life (Shear, 2015). It is due to the complexity of this process that its assessment and study becomes relevant, so that a better therapeutic intervention can be conducted. This article aims to adapt the Texas Revised Grief Inventory (TRIG) to the Portuguese population and assess its psychometric properties. Method: Adaptation: following Beaton and collaborators (2000) guidelines. Sample: 440 participants. Mean age was 43.16. Confirmatory factor analysis: two models were tested, a three-factor model (past feelings, present feelings, and disbelief) and a two-factor model (past feelings and present feelings). Invariance between Multigroups: the configural, the metric, the scalar and the residual were tested. Convergent and discriminant validity: was tested between the TRIG (and subscales) with the PG-13, and with the BDI II, respectively. Results: Confirmatory Factor Analysis: The model that showed the best results was the twofactor model, showing a fit within the acceptable limit. Invariance between Multigroups: it was concluded that there is invariance between genders. Internal Consistency: presented significant results, in the total TRIG as well as in its subscales. Convergent Validity: moderate positive and significant correlation. Discriminant validity: low and positive correlation. Conclusion: The TRIG – Portuguese Version showed good psychometric results, proving to be valid and reliable for the Portuguese population. It is suggested that the TRIG – Portuguese Version be tested in the future with specific samples.
