    Antecedentes: Perder a un ser querido provoca una serie de reacciones dentro del proceso de duelo. Aunque la mayoría de individuos experimentan duelos adaptativos, algunos pueden sufrir un intenso malestar emocional persistente. El Trastorno de Duelo Prolongado se diagnostica utilizando criterios de la CIE-11 y el DSM-5-TR. Las herramientas que evalúan ambos criterios simultáneamente son limitadas, lo que incrementa la relevancia del Inventario de Duelo Traumático Autoinforme Plus (TGI-SR+). El objetivo de este estudio fue analizar las propiedades psicométricas de las puntuaciones de la versión en castellano del TGI-SR+. Método: Se analizaron datos de 229 dolientes. Se utilizó el TGI-SR+. medidas de psicopatología y duelo prolongado. Resultados: Los análisis factoriales mostraron un buen ajuste para el modelo unifactorial del TGI-SR+ y alta consistencia interna (ϖ = .99). La validez convergente fue apoyada por correlaciones significativas con ansiedad, depresión, estrés postraumático y duelo prolongado (p < .001).

    Se observaron diferencias en función del sexo y nivel educativo. Se identificaron puntos de corte óptimos para el cribado en la muestra total y en aquellos con criterios de duelo prolongado. Conclusiones: La versión en castellano de la TGI-SR+ es una prueba útil para la evaluación del duelo prolongado para poblaciones de habla hispana.

    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.
