APA Dictionary of Psychology

therapy that ends after one session, usually by choice of the client but also as indicated by the type of treatment (e.g., Ericksonian psychotherapy, solution-focused brief therapy). Some clients claim enough success with one hour of therapy to stop treatment, although some therapists believe that this claim represents a flight into health or temporary relief from symptoms. Preparation for the session (e.g., by telephone) increases the likelihood of the single-therapy session being successful.
