Abstract

The concept of the alliance has received increasing attention from both clinicians and researchers over the past thirty years. Yet it remains only vaguely defined, and its role and effect in therapy continues to be controversial. The goal of this paper is to clarify the meaning of the concept as it is perceived by clients and therapists, and to compare and contrast these perceptions to the notion of the alliance as it is de-facto implemented in research through the most frequently used alliance measures. Our results indicate that clients and therapists pay attention to different aspects of the relationship when they assess the quality of the alliance. The most frequently used measures share some important features but also exhibit significant differences. Some alliance measures attempt to accommodate the differences in the clients’and therapists’points of view but others ignore them. In general, these popular measures do not appear to be closely matched to the unique client/therapist perspectives. The impact of the substantial variations between measures and the absence of a clear distinction between the differing perspectives of clients and therapists is discussed
