ABSTRACT
This chapter presents the concept of Single-session therapy (SST) and the ideas behind it, many therapists find themselves resisting SST. It describes that this 'resistance' is based on the fact that SST appears to challenge several cherished ideas that therapists hold about the nature of therapy and psychotherapeutic change. The chapter considers some of these beliefs and discuss them as they pertain to SST. If something is beneficial, then more of it must be more beneficial than less of it. While this may be true in certain realms of life, it is not the case in the field of psychotherapy. It should be borne in mind that much of the research reviewed by M. J. Lambert employed objective rating scales measuring change rather than subjective measures meaning what clients say about what they have gained from therapy. When clients are asked about this, they indicate the value of brief forms of treatment including those lasting for a single session.
