Abstract
G, A. Bonanno and S. Kaltman's (1999) concentration on the grief work hypothesis in their review of perspectives on bereavement is only I aspect required for a comprehensive theory of grief, which should cover the following: the origin and adaptive significance of grief;, the mechanism that initiates the grief response;, the mechanism that leads to the resolution of grief, and sources of individual variation. Bonanno and Kaltman's replacement for grief work also emphasized cognitive restructuring, which can be contrasted with 2 alternative mechanisms, forgetting and engaging in new activities and relationships. M. S. Stroebe and H. A. W. Schur's (1994) dual process model, which involves cognitive restructuring and engaging in new activities, provides a broader alternative to grief work than that advocated by Bonanno, and Kaltman.
