Texas Revised Inventory of Grief: The first grief instrument validated in Greek

Grief is an emotional experience influenced by cultural context, yet there is currently no validated tool available to assess it within the general Greek-speaking population, limiting both clinical assessment and cross-cultural research. The Texas Revised Inventory of Grief (TRIG) measures grief intensity after the death of a loved one through two subscales, TRIG past and TRIG present, and this study aimed to adapt and evaluate the Greek TRIG psychometric properties. A total of 197 bereaved Greek-speaking adults, who had experienced a loss within the past 3-24 months participated in the study. Confirmatory factor analysis supported the original two-factor structure of the TRIG, with satisfactory internal consistency and measurement invariance across sex. Differences in grief were observed based on family status, education, time since loss, relationship to the deceased, and cause of death. The Greek TRIG is a valid and reliable tool for assessing grief in general population.
