As grief is both an individual and shared experience, adopting a systemic perspective is most appropriate for health-care professionals seeking to assist the bereaved. Within this framework, the family virtually always constitutes the most significant social group in which grief is experienced. In this paper we review the literature on family grief, covering clinical case reports, the observations of family therapists, systematic family bereavement research and family intervention studies. An understanding of patterns of family grief and vulnerability factors for morbid grief is pivotal to both preventive intervention and treatment of an established disorder.
