The author describes the book "as a complete guide to culturally competent family therapy with any family of any sociocultural background." He has fashioned his theoretical model to "include concepts and methods …. found in cultural anthropology, sociology, cross-cultural social psychology, cross-cultural psychiatry, and linguistics … so far largely ignored by family therapists." He regards the major theoretical systems as being Eurocentric and lacking cultural relativity, and on those grounds he criticizes the theories of Bowen, Boszormenyi-Nagy, structural family therapy, strategic family therapy, psychoanalytic family therapy, and cognitive-behavioral therapy.
