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.

Clients of Therapists Who Are Flexible Have Better Outcomes
Clients of Therapists Who Are Flexible Have Better Outcomes
Katz, M., Hilsenroth, M. J., Gold, J. R., Moore, M., Pitman, S. R., Levy, S. R., & Owen, J. (2019). Adherence, flexibility, and outcome in psychodynamic treatment of depression. Journal of Counseling Psychology, 66(1), 94–103.
Psychodynamic and cognitive-behavioral (CB) treatments are quite different in how therapy is delivered, but both are equally effective for depression. Such findings suggest that various types of specific interventions can positively impact client outcomes. A possible mechanisms of therapeutic action is that effective therapists may be particularly responsive to their clients’ behaviors and needs. That is, effective therapists may be flexible in how adherent they are to the techniques of a therapeutic orientation. Therapists who are flexible in their adherence to a therapeutic technique may promote a better therapeutic alliance (i.e., a therapist’s and client’s collaborative agreement on the goals of therapy and what to do in therapy). In this study, Katz and colleagues examined whether the flexible use of some CB techniques by psychodynamic therapists was related to better client outcomes in terms of depressive symptoms. Forty six patients diagnosed with depression were treated by 26 advanced graduate student therapists who were trained to practice psychodynamic therapy. Psychodynamic therapy techniques included: a focus on affect and affect expression, identifying relational patterns and patterns of thoughts and feelings, emphasizing past experiences and interpersonal relationships, working on the therapeutic alliance, and restructuring defense mechanisms. The researchers video recorded two early sessions of therapy which were independently rated to assess the degree to which therapists adhered to psychodynamic therapy principles or to CB therapy principles. Client depression outcomes were assessed pre- and post-therapy. Higher ratings of psychodynamic therapy adherence were related to better patient depression outcomes at post-treatment. In addition, the clients of psychodynamic therapists who used some CB techniques early in therapy had the best outcomes. In other words, the use of psychodynamic techniques was sufficient for clients to improve, but flexible use of some CB techniques by psychodynamic therapists provided added benefit. The CB techniques that were most often integrated by the therapists included: actively initiating topics and therapeutic activities, explaining the rationale of an intervention, focusing on the future, and providing psychoeducation about symptoms.
Practice Implications
Clients in this study improved on average from psychodynamic therapy, and psychodynamic interventions were related to better outcomes. However, clients of therapists who flexibly integrated a small amount of CB techniques benefitted more from the psychodynamic techniques. Research is increasingly showing that therapist flexibility in treatment adherence is related to better patient outcomes. For psychodynamic therapists, flexibility in treatment adherence leads to clients being more responsive to the interventions and having better outcomes.

Dynamic-Interpersonal Therapy for Moderate to Severe Depression
Fonagy, P., Lemma, A., Target, M., O'Keeffe, S., Constantinou, M., Ventura Wurman, T., . . . Pilling, S. (2019). Dynamic interpersonal therapy for moderate to severe depression: A pilot randomized controlled and feasibility trial. Psychological Medicine, 1-10. Online first publication. doi:10.1017/S0033291719000928
Most psychotherapies are equally effective when it comes to treating depression. However, no single therapy is uniformly effective, so that about 50% of patients might improve when it comes to symptom reduction. So, although there is a large evidence base for treatments like CBT, therapists and patients need access to a range of available treatments. There is less research on psychodynamic therapies, although a number of trials and meta-analyses indicate their effectiveness to treat depression. In the United Kingdom (UK), the health system may offer a stepped care program that provides patients with low intensity guided self-help based on a CBT model followed by more intensive treatment with CBT or IPT if patients did not benefit from self-help. The UK health system rarely offers Dynamic Interpersonal Therapy (DIT), and DIT has never been studied in a randomized controlled trial within the UK health system. Fonagy and colleagues designed this randomized controlled trial to test the efficacy of DIT when compared to the CBT-oriented self-help program as offered in the UK. The study also included a smaller randomized sample of those who received the intensive version of CBT for depression. In total, 147 participants with moderate to severe depression were randomly assigned to DIT, CBT guided self-help, or the intensive version of CBT. The DIT is informed by attachment theory and by mentalization theory, and it views depressive symptoms as responses to interpersonal difficulties or perceived attachment threats. The results of the trial showed a significantly greater effect of DIT compared to guided self-help with regard to depressive symptoms, overall symptom severity, social functioning, and quality of life at post-treatment. The patients receiving DIT maintained these gains up to 1-year post-treatment. Over half of DIT patients showed clinically significant improvements, but only 9% who received the CBT-based guided self-help achieved such improvement. There were no significant differences on any of the outcomes between DIT and the more intensive version of CBT.
Practice Implications
One of the benefits of DIT, according to the authors, is that it offers a treatment manual and curriculum that enables those without a lot of background in psychodynamic therapies to deliver it. This makes DIT potentially widely-applicable in publicly funded health systems like in the UK, Canada, and others. DIT may offer yet another effective option of psychotherapy to therapists and their patients who experience depressive symptoms. The study also points to the limits of offering only guided self-help to those with moderate to severe depression.

Effectiveness of Psychodynamic Couple Therapy in a Naturalistic Setting
Hewison, D., Casey, P., & Mwamba, N. (2016). The effectiveness of couple therapy: Clinical outcomes in a naturalistic United Kingdom setting. Psychotherapy, 53, 377-387.
Current randomized controlled trials (RCTs) of couple therapy indicate that about 60% to 70% of couples improve to some degree, and that about 35% to 50% are no longer distressed by the end of therapy. But RCTs have been criticized for being somewhat artificial because their design is based on how pharmacological treatments are tested. Psychotherapy may be more complex than pharmacotherapy in its implementation, and compared to pharmacotherapy, psychotherapy relies more heavily on the qualities of the therapist and therapeutic relationship in order to achieve good outcomes. In an RCT, individuals often have to have a specific disorder to be included in the study, and those with co-morbid disorders may be excluded. This may limit what the findings have to say about real world applications of a particular treatment. Further, therapists in RCTs may receive unusual levels of supervision and support that is seldom seen in regular clinical practice. In this large study of over 435 couples, Hewison and colleagues assessed the effectiveness of a psychodynamically-oriented couple therapy as practiced in a large not-for-profit centre that provides psychological treatment (i.e., the Tavistock clinic in the United Kingdom). All participants received couple treatment and none were randomly assigned to a control group. The couple therapy focused on insight and emotional connection and expression within the context of a therapeutic relationship. The couple relationship rather than the individual partners were the object of the therapy. The unconscious meaning of couple communication was often discussed, and therapist countertransference was seen as a source of information about the couple. Most couples in the study identified as White (77.0%), heterosexual (93.9%), and married or living in a civil partnership (58.4%). More than half of the couples were in the relationship for over 5 years and had children. Therapists were qualified couple therapists or Masters level trainees, had a mean age of 50 (range: 26 – 71), tended to be White women (60%), and were all trained at the clinic. The average number of sessions that a couple attended was 23.3 (SD = 23.5), but with a wide range (2 to 150 sessions) as might be typical in a clinical setting. Overall, individual clients reported a large significant decrease in individual psychological distress (d = -1.04), and a moderate significant decrease in marital distress (d = -0.58). Half of individuals showed a reliable reduction in their individual distress, and over a quarter of couples reported a reliable decline in their couple distress.
Practice Implications
This is the largest study of couple therapy in a naturalistic setting. The psychodynamic couple therapy was effective in reducing individual distress for almost half of the participants although reliable change in couple distress was lower. The results of this field trial indicate that couple therapy that is offered in a functioning real-world clinic setting produces results similar to what is seen in highly controlled randomized trials.
