Widely used to train health and mental health professionals, the genogram is a graphic way of organizing information gathered during a family assessment and identifying patterns in the family system. This popular text -- updated and expanded to highlight new developments in genogram use -- thoroughly explains how to draw, interpret, and apply the genogram. Using genograms of famous families as examples -- including those of Sigmund Freud, the Kennedys, Bill Clinton, and Thomas Jefferson, to name a few -- the authors examine the principles of family systems theory and systemic interviewing. Clinical applications of genograms in both family therapy and family medicine are described, and new frontiers of research are explored, particularly the use of computer-generated genograms. Entertaining and instructive, Genograms is the ideal guide for introducing all those involved in family treatment -- family therapists, physicians, nurses, social workers, counselors, and trainees in these fields -- to this essential assessment and intervention tool.
