概要	The Adult Attitude to Grief Scale (AAG) is a measure assessing individual beliefs, attitudes, and values regarding grief and bereavement. Developed by Richard K. Barrett, the AAG captures how adults conceptualize grief—including beliefs about whether grief is acceptable, whether emotions should be expressed, whether seeking help is appropriate, and whether personal growth can emerge from loss. By measuring grief-related attitudes, the AAG provides insight into psychological readiness for adaptive bereavement.	The Inventory of Complicated Grief (ICG) is a 19-item self-report measure developed by Prigerson and colleagues in 1995 to assess complicated grief—a persistent, impairing form of grief that goes beyond typical bereavement. Designed to distinguish complicated grief from bereavement-related depression, the ICG has become the gold-standard screening and diagnostic instrument in bereavement research and clinical practice.
