In the present chapter we address all those aspects pertaining to the process of individual systemic therapy. The different principles employed since the 1970s in conducting the session (hypothesis, circularity, and circular questions) are fully dealt with first. We then turn our attention to the stages of therapy (from the initial evaluation to the final session) and conclude by discussing in depth the recent, stimulating contributions concerning some linguistic aspects (semantic, rhetorical, and hermeneutic) of therapeutic dialogue.
