This paper offers a comparative analysis of the process of conjoint marital therapy within the three major contemporary models of treatment: psychoanalytic, behavioral, and systems theory. The specific dimensions of the treatment process that are examined are: (1) the role of the past and of the unconscious; (2) the nature and meaning of presenting problems and the role of assessment; (3) the relative importance of mediating vs. ultimate treatment goals; and (4) the nature of the therapists roles and functions. On the basis of this comparative analysis, some thoughts toward the future of the marital therapies are offered.
