Psychotherapy Research Needs Theory. Outline for an Epistemology of the Clinical Exchange

This paper provides an analysis of a basic assumption grounding the clinical research: the ontological autonomy of psychotherapy—based on the idea that the clinical exchange is sufficiently distinguished from other social objects (i.e. exchange between teacher and pupils, or between buyer and seller, or interaction during dinner, and so forth). A criticism of such an assumption is discussed together with the proposal of a different epistemological interpretation, based on the distinction between communicative dynamics and the process of psychotherapy— psychotherapy is a goal-oriented process based on the general dynamics of human communication. Theoretical and methodological implications are drawn from such a view: It allows further sources of knowledge to be integrated within clinical research (i.e. those coming from other domains of analysis of human communication); it also enables a more abstract definition of the psychotherapy process to be developed, leading to innovative views of classical critical issues, like the specific-nonspecific debate. The final part of the paper is devoted to presenting a model of human communication—the Semiotic Dialogical Dialectic Theory–which is meant as the framework for the analysis of psychotherapy.
