摘要：We have read with interest the recent debate paper‘Prolonged grief disorder for ICD-11: the primacy ofclinical utility and international applicability’ byKillikelly and Maercker (2018). Establishing prolonged grief disorder (PGD) in the ICD-11 has beena long-anticipated development that is likely to provide a great impetus for research and treatmentdevelopment for bereaved persons experiencingsevere grief reactions. We appreciate the authors’thorough historical analysis of the development ofdisorders for pathological grief and the clear explanation of the guiding principles in the establishment ofthe ICD-11 PGD criteria. We nevertheless disagreewith two central claims made in this paper.Specifically, we take issue with assertions that priorresearch on a variety of qualitatively different precursor criteria for grief disorders (1) offers valid diagnostic guidelines for the inclusion of PGD in theICD-11, and (2) confirms that the novel ICD-11PGD criteria provide the same valid symptom structure as these precursor criteria.
