Objective The Traumatic Grief Inventory‐Self Report Plus (TGI‐SR+) measures the most recent prolonged grief disorder (PGD) symptom sets defined in the 11 th edition of the International Statistical of Diseases and Related Health Problems (ICD‐11) and the text revision of the fifth edition of the Diagnostical and Statistical Manual of Mental Disorders (DSM‐5‐TR). However, the TGI‐SR+ has not yet been translated and validated in Chinese. This study aims to evaluate the psychometric properties of the Chinese translation of the TGI‐SR+. Methods We examined the Chinese TGI‐SR+'s factor structure, internal consistency, convergent validity, discriminant validity, known‐groups validity, and optimal clinical cut‐off scores in 443 Chinese bereaved adults. Results Confirmatory factor analyses showed that the two‐factor models showed the best fit for the Chinese TGI‐SR+ items assessing ICD‐11 and DSM‐5‐TR prolonged grief symptoms. Items assessing ICD‐11 and DSM‐5‐TR prolonged grief symptoms demonstrated good internal consistency. Associations of TGI‐SR+ scores with symptom levels of prolonged grief (assessed by the International Prolonged Grief Disorder Scale), posttraumatic stress, anxiety, and depression supported convergent and discriminant validity. Associations with background/loss‐related variables provided evidence for known‐groups validity. Cut‐off points for probable ICD‐11 PGD (liberal scoring rule), probable ICD‐11 PGD (conservative scoring rule), and probable DSM‐5‐TR PGD were ≥67, ≥75, and ≥68, respectively. Discussion The Chinese TGI‐SR+ appears to be a reliable and valid measure to assess prolonged grief symptoms per ICD‐11 and DSM‐5‐TR among Chinese bereaved adults.
