Grief in dementia caregiving is underexplored in research studies in the Chinese context, yet social workers often work with caregivers of people with dementia (PWD) and who experience grief. Having a valid assessment tool can help social workers better identify the grief of caregivers and facilitate caregivers' articulation of grief. This article describes a study aimed to validate the Marwit-Meuser Caregiver Grief Inventory-Short Form (C-MMCGI- SF) among Hong Kong Chinese caregivers of PWD. One hundred and twenty caregivers participated in this study. They were recruited from day care centers and a memory clinic. The short version of MM-CGI was translated into Chinese, and participants were asked to complete a questionnaire that included this scale and other scales validating it. Reliability and validity were examined. C-MM-CGI-SF was found to be a reliable and valid measure in the Hong Kong context. Its construct validity was demonstrated by the positive correlations with caregiving strain and depression, and negative correlations with presence of meaning and life satisfaction. The discriminant validity was supported by showing that spousal caregivers' grief level was significantly higher than that of nonspousal caregivers. Authors recommend social workers using the C-MM-CGI-SF to assess the grief of Chinese caregivers caring for people suffering from dementia.
