I am not a psychoanalyst, although I’m married to one and was an adherent psychodynamic therapist in her Panic-Focused Psychodynamic Psychotherapy studies.1 I got basic training as a resident at the Payne Whitney Clinic in its psychodynamic heyday under Bob Michels, and I had exactly four years of psychoanalysis with a Columbia training analyst (beginning and ending on my mother’s birthday). I wanted, though, to do psychotherapy research, for which psychoanalysis has unfortunately not been a fertile field. When the late Gerald Klerman came to Cornell Medical College and I had graduated to the junior faculty, I got the chance to learn and study Interpersonal Psychotherapy (IPT).

IPT is a manualized, time-limited, affect-focused psychotherapy based on the attachment principles of John Bowlby and the interpersonal emphasis of Harry Stack Sullivan.2 It focuses on the connection between mood and interpersonal life circumstance in the context of rapidly treating mood and, increasingly, other DSM disorders. IPT does not focus on childhood nor address the transference, focusing instead on the patient’s life outside the office. (Informed IPT therapists note transferential and childhood issues in assessing patients but do not directly employ them.) Like me, then, IPT is sympathetic to but differs from psychodynamic therapy: both are affect-focused treatments.3 

For more than three decades I have conducted comparative clinical research comparing psychotherapies to one another and to pharmacotherapy. My first big psychotherapy study in the 1990’s, a National Institute of Mental Health-funded trial conducted by the late Samuel Perry, M.D. (a psychoanalyst), compared IPT to cognitive behavioral therapy (CBT), imipramine, and supportive psychotherapy for depressed HIV-positive patients.4 Other studies have assessed IPT treatment outcomes for depressed patients post-miscarriage,5 with infertility,6 and with breast cancer;7 dysthymic disorder, with and without alcohol abuse;8,9 borderline personality disorder;10 and most recently, posttraumatic stress disorder.11

Each disorder and treatment population requires adaptation of the treatment manual, but the fundamental approach remains the same, and results have helped to define not only the efficacy of treatments (i.e., that they work) but which treatment works better for which patients. It’s exciting clinical work. Along the way, we wrote a manual for Brief Supportive Psychotherapy (BSP) as a control therapy for IPT and CBT, which turns out to be a powerful affect-focused treatment in its own right.12

In 2019 I joined the American Psychoanalytic Association College of Research Fellows alongside Bart Blinder. The College is rightly concerned that the continuing allergy of psychoanalysis to outcome research risks consigning it to irrelevance. In today’s era, long after Freud, therapies need an evidence basis to show they work, and psychoanalysis lacks one. (Even with evidence, psychotherapies are on most often the defensive.13,14)  Research has shown the benefits of time-limited psychodynamic therapies for particular disorders, but the field needs randomized controlled trials to show whom psychoanalysis helps and what advantages it may have over briefer treatments.
