Existential-humanistic (E-H) psychotherapy is a coalescence of American humanistic psychology, which emphasized optimism, potential, and relatively rapid transformation, with European existential philosophy and psychology, which underscored challenge, uncertainty, and relatively gradual transformation. E-H therapy is characterized by the cultivation of freedom, experiential reflection, and responsibility. EI therapy, or the apprehension of diverse practice modalities within an overarching existential context, is one of the latest trends within E-H practice. This therapy has the advantage of addressing a broad array of clients, diagnostic issues, and therapeutic settings. The aim of EI therapy is to facilitate client freedom. E-I therapy proceeds on the basis of clients’ desires and capacities for change, and the liberation conditions available to impact those desires and capacities. In short, the E-H therapeutic orientation provides a deep and broad alternative to mainstream emphases on physiological, behavioral, or cognitive change.
