“…Consequently, this reading ofGssler's letter prompts me to comment briefly on the historical background and evolution of family systems theory* Systems theory entails "a fundamental shift from viewing the family and other life contexts in terms of patients to viewing patients in terms of their involvement in their significant life contexts" [Coyne and Liddle, 19921, especially their interpersonal relationships [Ransom, 19891. Historically, a large number of "mavericks who suffered personal and professional espsychiatry, family medicine, social work, and psychiatric nursing], but who received their degrees and initial professional training from them" [Coyne and Liddle, 19921. Approaching "Paradigmatic Parity": Family Systems Theory in Perspective Utilization of family systems concepts has made a major intellectual contribution to the development of marital and family therapy [Coyne and Liddle, 19921. Moreover, training in family systems concepts is increasingly common in clinical psychology, psychiatry, social work, nursing, and other mental health and medical training programs [Gurman and Kniskern, 19921. However, as Kessler surely realizes, systems therapy is only now beginning to approach "paradigmatic parity with the more conventional [and individualistic] approaches to psychotherapy," such as the psychodynamic, humanistic, behavior, and cognitive traditions [Coyne and Liddle, 19921. As I state in my editorial, "Mamily systems theories would seem to offer a particularly productive clinical research approach since one contribution of systems theory to the mental health field has been to shift thinking about human behavior from the frame of individual causality to the perspective of human behavior as a complex interactive process" [Chapman, 1992, references omitted]. Additional support for my position can be found in the analyses by Coyne and Liddle [1992] of "The Future of Systems Therapy: Shedding Myths and Facing Opportunities" and by Gurman and Kniskern [19921 of "The Future of Marital and Family Therapy," which appeared recently in the journal Psychotherapy's special issue on "The Future of Psychotherapy." Coyne and Liddle [1992] observe that "[slystems theory is not yet associated with a large body of research" and Gurman and Kniskern [19921 comment on the lack of contributions by marital and family therapists in advancing "theory, research, and clinical practice" involving two common areas of psychiatric dysfunction-CUSeS about all sorts of things, When you suddenly Huntington's disease.…”
