Blog
The Psychotherapy Practice Research Network (PPRNet) blog began in 2013 in response to psychotherapy clinicians, researchers, and educators who expressed interest in receiving regular information about current practice-oriented psychotherapy research. It offers a monthly summary of two or three published psychotherapy research articles. Each summary is authored by Dr. Tasca and highlights practice implications of selected articles. Past blogs are available in the archives. This content is only available in English.
This month...
…I blog about content from the updated edition of the Handbook of Psychotherapy and Behavior Change, published in 2021: the effectiveness of psychotherapist training, the therapist effect, and therapist responsiveness to patient interpersonal behaviours.

The Enduring Effects of Psychodynamic Treatments
Kivlighan, D.M., Goldberg, S.B., Abbas, M., Pace, B.T., …Wampold, B.E. (2015). The enduring effects of psychodynamic treatments vis-à-vis alternative treatments: A multilevel longitudinal meta-analysis. Clinical Psychology Review, 40, 1-14.
There is a great deal of evidence that indicates uniform efficacy of a variety of psychotherapies for many common disorders. For example, in the July 2014 PPRNet Blog, I reviewed a meta-analysis comparing 7 psychotherapies for depression indicating no differences between the various treatments in terms of patient outcomes. Nevertheless proponents of cognitive behavioural therapy have claimed superiority to alternative treatments for decades. On the other hand proponents of psychodynamic therapies have argued that these treatments focus on personality change rather than symptoms, and so benefits of psychodynamic therapies will be longer lasting. In this meta analysis, Kivlighan and colleagues put these claims to the test. They selected studies in which a psychodynamic therapy was compared to one or more alternative treatment. Both the psychodynamic therapy and the alternative (most often CBT) had to be judged as “bona fide” therapies by independent raters (i.e., they had to be therapies that were delivered in a manner in which they could be expected to be effective by clients and therapists). Outcomes not only included specific symptoms (e.g., depression), but also non-targeted outcomes (e.g., improved self esteem in a study of treatment of anxiety), and personality outcomes. Effect sizes for outcomes were assessed at post-treatment and also at follow-ups. Twenty five studies directly comparing psychodynamic and non-psychodynamic therapies were included, representing 1690 patients. At post treatment, no significant differences were found between psychodynamic and non-psychodynamic treatments on targeted outcomes, non-targeted outcomes, and personality measures (all gs < .10). There was also no significant or meaningful effect of time to follow up on outcomes, indicating no differences between treatment types at any of the follow up periods.
Practice Implications
Psychodynamic and non-psychodynamic treatments were equally effective at post treatment and at follow ups for all outcomes, including personality variables. This challenges the belief that psychodynamic treatments uniquely affect personality and have longer lasting effects compared to other treatments. It also challenges the notion that CBT (by far the most common comparison treatment) is a superior therapy for patient outcomes. Pan-theoretical psychotherapy factors (client contributions, expectations, therapeutic alliance) may be more promising factors in understanding the long term benefits of psychotherapy.
