Abstract
Background: The grieving process caused by the loss of a loved one triggers a range of responses. While most
people experience adaptive grief, some may experience intense distress and persistent symptoms. Prolonged Grief
Disorder is commonly diagnosed using the ICD-11 and the DSM-5-TR. Few instruments assess criteria from both
simultaneously, underscoring the importance of the Traumatic Grief Inventory Self-Report Plus (TGI-SR+). This study
aimed to analyse the psychometric properties of the scores from the Spanish version of the TGI-SR+. Method: Data
were analysed from 229 participants who were bereaved between March 2020 and March 2022. The Spanish TGI-SR+
was used alongside measures of psychopathology and prolonged grief. We performed confirmatory factor analysis,
reliability tests, bivariate correlations and group comparisons. Results: Confirmatory factor analysis of the TGI-SR+
demonstrated a one-factor structure with high reliability (ϖ = .99). Convergent validity was shown by correlations with
anxiety, depression, post-traumatic stress and prolonged grief (p < .001). Differences by sex and educational level were
observed. Optimal screening cut-off points were identified for the total sample and for those meeting the criteria for
prolonged grief. Conclusions: The Spanish version of the TGI-SR+ is a valuable instrument for assessing prolonged
grief in Spanish-speaking populations
