acknowledges that each Triangle was independently devised by Ezriel (1952) and Menninger (1958) respectively, but he showed how, when put together, the relation between them for the patient at any given moment in therapy, can form a reliable basis for many of the interventions that the therapist makes. Ref: Individual Psychotherapy and the Science of Psychodynamics (p. 80) As early as 1963 in his analysis of cases in Balint's workshop, Malan had identified that good outcome correlated with a high frequency of interpretations making a link between the transference and childhood, but the full significance and usefulness of the concept of linking the Triangles came later. The Myth of Superficiality Research from the workshop exploded the ‘myth of superficiality’ whereby critics maintain that Brief Psychotherapy is a superficial treatment that can only be effective with superficially ill patients, bringing about superficial results. Malan maintains that the aim of every session is to ‘put the patient in touch with as much of their true feelings as they can bear and that the long-term outcome should demonstrate deep and lasting changes.’ The work does not have to be focal and limited to specific problems and should lead to therapeutic changes that are wide-ranging, deep-seated and permanent. This has been shown in many of Malan's follow-up studies where Brief Therapy and Intensive Short-term Dynamic Psychotherapy have been used. Collaboration with Habib Davanloo In 1974 Davanloo presented videotapes of his therapeutic work using Intensive Short-term Dynamic Psychotherapy (ISTDP) at the Tavistock Clinic. The essence of ISTDP is to enable the patient to reach and experience their hitherto buried, and often unconscious feelings, which have been governing their emotional responses leading to deep-seated neurotic patterns of behaviour that in many cases have crippled their lives. He does this by challenging the defences that the patient has been using to avoid painful feelings of loss, grief, anger, hate and guilt about people who they loved and /or needed when children. Although aspects of Davanloo's challenging and sometimes abrasive technique were antipathetic to him, Malan recognised that the challenge was to the defences, not to the patient directly, and results were conclusive and convincing. The videotapes showed undeniable evidence that patients could be treated in a relatively few sessions (40 or fewer) and fully recover from a range of longstanding emotional and psychosomatic illnesses. Malan and Davanloo collaborated for twelve years from 1974, doing many Conferences and
