Since the continuing bonds model of grief was introduced into bereavement studies in Continuing Bonds: New Understandings of Grief (1996), it has been extended from its origins in psychology into other disciplines and adopted in a surprising range of cross-cultural studies. In turn, developments in other cultures and disciplines have fed back into the psychological study and treatment of grief. We think the far-flung developments provide a solid basis for new directions in research and practice. The purposes of this anthology are, first, to show the range of ways the continuing bonds model has been used; second, to trace how the model has been expanded and enriched through this process of cross-fertilization and proliferation; and third, to encourage further cross-fertilization by having so many of the developments together in the same book.
