This chapter surveys a range of relationship-orientated brief therapies: Interpersonal Therapy (IPT), Cognitive-Analytic Therapy (CAT), Dynamic Interpersonal Therapy (DIT), Intensive Short-Term Dynamic Psychotherapy (ISTDP), the Conversational Model (a version of which became known as Psychodynamic Interpersonal Therapy, or PIT), and Brief Psychoanalytic Therapy (BPT). Principles of treatment and mechanisms of change are considered, and for each approach, an excerpt of therapeutic dialogue provides vivid illustration. This establishes a basis for considering how far the treatments have features in common, and how far they are distinctive from one another. The chapter concludes by noting substantial evidence for the effectiveness of brief psychodynamic psychotherapies.
