Prof. Richard Layard's influential advocacy for greater provision of 'evidence-based' psychological therapies, based in part on an economic rationale, has lead to greatly increased provision of cognitive behavioural therapy (CBT) and short-term therapies for depression, through the Increasing Access to Psychological Therapies (IAPT) initiative, whilst longer-term psychodynamic treatments are under threat, criticised as lacking an evidence base. This paper argues for the continuing provision of intensive thriceweekly psychoanalytic psychotherapy treatments, time-limited to two years. It does so by describing such a treatment within an NHS psychotherapy department with a patient with a long history of severe personality pathology, including significant levels of perversity. The paper describes the patient's difficulties and his movement through the treatment, focussing on his difficulties making genuine emotional contact, his destructiveness of such contact, his acting out in the treatment, his perversity and the vital working through of the ending. The shifts the patient made are described, and followup information on the patient is given. The paper discusses the unique benefits of time-limited treatment and intensive psychoanalytic treatments for this 'hard-to-help' group of patients, and the economic rationale that can be made for such treatments.
