DELALIBERA, Mayra et al. Adaptation and validation for the brazilian population to assessment instrument prolonged grief disorder: PG-13. Psicol. teor. prat. [online]. 2017, vol.19, n.1, pp. 94-106. ISSN 1516-3687.

Grief may be defined as a set of emotional, physical, behavioral, and social reactions that appear in response to a significant loss. The study aims at translating, adapting and validating, for the Brazilian population, the assessment tool of prolonged grief PG-13. The sample consisted of 115 bereaved family members who completed a questionnaire online. Of these families, 76,5% were female, 50,4% were married, mean age of 41,32 years and a mean time of grief 29,29 months. The incidence of prolonged grief was 10,43%. All items on the restructured model PG-13 showed higher factor weights 0,5, they were statistically significant and had appropriate individual reliabilities. The Cronbach's alpha was 0,940 and the convergent validity assessed by VEM was 0,593. Therefore, we conclude that the PG-13 has individual and construct reliability and convergent validity that could also contribute to the diagnosis of prolonged grief.
