摘要:COVID-19 has resulted in an estimated 22 million recently bereaved people worldwide. Pioneering empirical studies show that people bereaved through COVID-19 experience elevated mental health problems. However, no study has reported the prevalence of prolonged grief disorder (PGD). Studies exploring relations between potential risk factors and mental health in the Eastern COVID19 bereavement population are also lacking. To estimate the prevalence of PGD and to investigate the associations of demographic and lossrelated characteristics with mental health after COVID-19 bereavement. Method: A sample of Chinese adults bereaved due to COVID-19 (N = 422) completed demographic and loss-related questions and self-report measures of prolonged grief, posttraumatic stress, anxiety, and depressive symptoms through an online survey. Results: Estimated prevalence of PGD was 38% per ICD-11 criteria. Based on cut-off points, a significant group experienced clinically relevant prolonged grief (49%), posttraumatic stress (22%), depressive (70%), and anxiety symptoms (65%). In four multiple regressions predicting each mental health indicator, losscharacteristics (i.e., a shorter time since loss, or loss of a first-degree relative) and subjective loss experiences (i.e., feeling traumatized by the loss, or a close and/or conflictual relation with the deceased) related most consistently to mental health problems. Conclusions: Prevalence of PGD is high among Chinese adults bereaved through COVID-19. A subset of this population experiences severe posttraumatic stress, depressive, and anxiety symptoms. The recent loss of first-degree relatives, feeling traumatized by the loss, and having a close and/or conflictual relationship with the deceased may elevate risks for these mental health problems, which could require indicated psychological treatment.
