The goal of Gestalt therapy is the integration of a unified self. Gestalt therapists use several techniques to achieve this goal. There is a focus on the here-an-now, questioning is discouraged, clients are encouraged to use “I” language to accept responsibility for their actions, clients further encouraged to claim responsibility using overt language, the use of role-playing and the empty-chair technique are designed to help clients externalize internal conflicts, finally, dreamwork is used to examine parts of the self that may not be fully accepted. Gestalt therapy is best used with clients who have the intelligence and education to withstand some of the confrontive techniques it uses.
