ESSENTIAL ALLIANCE INGREDIENTS A very large and significant segment of the empirical psychotherapy process – outcome literature that has been produced over the past sixty years clearly demonstrates the primary relevance of several putative therapist ingredients in effective psychotherapy. These ingredients constitute the essential therapeutic ingredients in efficacious psychotherapy relationships and, are more specifically, constitute the therapeutic alliance component of the therapeutic relationship. The essential core conditions or ingredients in effective and efficacious therapeutic alliances include non-possessive warmth or positive regard (originally referred to as “unconditional positive regard” by Carl Rogers, [1942, 1957], empathy, and genuineness (originally referred to as “congruence” by Rogers). Successful therapeutic alliances and outcomes are also related to effective communication or therapeutic concreteness (Turax and Carkhuff, 1967), and more generally and nefariously by a number of additional therapeutic alliance dynamics including transference, countertransference, therapist – client self-disclosure, and a diversity of other potentially significant and personal factors which may impact the therapist, patient, therapeutic relationship, alliance and process and outcome of therapy in a myriad of ways. General Definential Parameters of: Non-possessive Warmth, Empathy, Genuineness, Concreteness, Transference, Countertransference, Self-Disclosure, and other therapeutic alliance factors. Tillman (2013) indicates that “there is a vast amount of research on the therapeutic relationship variables of empathy, unconditional positive regard (acceptance), and congruence (genuineness) in the psychotherapy literature. Furthermore “the contributions of these relationship variables were found to account for as much, if not more, of successful treatment outcomes than specific interventions or treatment methods.” She also states “While it is clear that the therapeutic relationship (alliance) is an important factor in the success of any form of therapy, client-centered relational variables may play an especially important role when addressing the problem domains that mental illness has shown the most success with, addictive and health behaviors…furthermore, empathy and acceptance may also be more likely to flow from a positive view of human nature consistent with mental illness, making a self-assessment of a clinician’s assumptions about human nature especially important in this regard.” p. 50-51. In sum, historic and contemporary research, and clinical practice data consistently demonstrate the compellingly positive roles and therapeutic impact of these alliance ingredients in the process and outcome of psychotherapy.
