"The Eight Concepts" is a clear and concise description of the basic concepts of Bowen family system theory. <br /><br />Beginning with the fundamental concept of the nuclear family as the emotional unit, the other concepts -- differentiation of self scale, triangles, cutoff, family projection process, multigenerational transmission process, sibling position, and emotional processes of society -- are explained as they evolve out of the fundamental concept of the emotional unit. The emphasis is clarity of presentation and purity of presentation of theory. <br /><br />Numerous citations to the writings of Dr. Bowen and experts who studied under Dr. Bowen are used to present the theory in as pure a form as possible in a short and easy-to-read book. The special sections in each chapter for parents, coaches and leaders bring each concept home for different roles readers bring to the book. <br /><br />An index is included.
