The Impact of Patients' and Therapists' Views of the Therapeutic Alliance on Treatment Outcome in Psychotherapy.

This article reports about the role of psychotherapists in creating a good enough therapeutic alliance as the basic task for other therapeutic factors come into play. Data from a naturalistic study involving 237 patients treated by 68 psychotherapists using 10 different psychotherapy approaches were analyzed in a process-outcome research design. The results show that therapists had to adapt their alliance perspectives to patients' level of alliance ratings as treatments progressed. Treatment concepts did not play a role in outcome. The view of a similar quality of the therapeutic alliance seems to be an indispensable precondition for favorable treatment outcomes. Successful treatments were conducted more often by therapists who showed significant convergence of alliance ratings over time, whereas discrepant alliance ratings correlated significantly with unsuccessful treatments.
