Research has shown that a strong therapeutic alliance is necessary to establish beneficial contact between the therapist and client. If the therapist does not encourage the creation of a reliable therapeutic alliance from the beginning of treatment, it will be difficult to develop a constructive relationship with the client later. Establishing the therapeutic alliance will increase the chances of achieving the treatment goal because clients will be willing to cooperate if they trust and respect the therapist. Clients are unlikely to cooperate with therapists who assert their authority aggressively. Instead of imposing their authority on the patient, therapists should develop their work with their patients by building a mutual relationship based on trust, understanding and respect for the client. According to Jeremy Safran and Christopher Muran (2000), psychiatric research shows that the quality of the therapeutic alliance is the most important factor in determining the therapist's success. “Some therapists are consistently more helpful than others; differences in therapist skill appear to be more important than therapeutic modality, and more helpful therapists appear better able to facilitate the development of a therapeutic alliance” (Safran & Muran, 2000). However, the main problem is that it is difficult to teach the skills necessary to create a therapeutic alliance. Research in psychotherapy, in fact, underlines the importance of developing human qualities in the therapist. According to Safran and Muran (2000), the therapist must constantly develop and engage in personal growth through inner work. Without this feature, therapists will not be able to develop… half of the paper… eating with their therapists. “A systematic relationship between therapists' personal reactions to the patient and the quality of their communication, diagnostic impressions, and treatment plans” (Horvath & Greenberg, ). While positive attitudes on the part of therapists are more likely to lead to successful treatment, negative attitudes will not develop the necessary cooperation on the part of the client to successfully achieve the goal of therapy. Regardless of the treatment method, scientific research findings highlight the importance of relationship-based treatment that builds trust and openness. All researchers argue that developing a strong therapeutic alliance early on influences the course of treatment and its success. Developing this type of relationship with patients early will increase therapists' chances of success.
