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 therapist empathy, psychotherapeutic treatment for borderline personality disorder, and research on psychological treatment of depression.

The Importance of Psychosocial Factors in Mental Health Treatment
Greenberg, R.P. (2016). The rebirth of psychosocial importance in a drug-filled world. American Psychologist, 71, 781-791.
In this thoughtful piece, Greenberg reviews the research on psychosocial factors that affect mental health treatment outcomes – including for medications and in psychotherapy. There has been an important shift in the last few decades to view mental disorders, including depression, as biologically based. For example, surveys indicate that the public’s belief in biological causes of mental illness rose from 77% to 88% during a 10 year period. During the same period the belief in the primacy of biological treatment for mental disorders rose from 48% to 60%. Further, 20% of women and 15% of men in the US are currently taking antidepressant medications. Some of these trends are due to direct to consumer marketing of medications by the pharmaceutical industry, which saw a 300% increase in sales in antidepressants. Some of these trends are also due to Federal agencies like the National Institute of Mental Health that vigorously pursued an agenda of biological research. But what is the evidence for a purely biological view of mental health? Greenberg notes that the evidence is poor. For example, no one has been able to demonstrate that a chemical imbalance actually exists to explain depressive symptoms – which undermines the reason for using medications to treat depression. Further, research on the efficacy of antidepressant medications shows that they perform only slightly better than a placebo pill, prompting a former editor of The New England Journal of Medicine to declare that this difference is unlikely to be clinically meaningful. The placebo effect is essentially a psychosocial effect. It refers to: the patient’s experience of a caring relationship with a credible professional, and the patient’s expectations and hopes of getting better. Placebo is a very real phenomenon that also has an impact on purely medical interventions like surgeries. In psychotherapy trials, relational/contextual factors like therapeutic alliance, expectations, therapist empathy, and countertransference likely account for more of the client’s outcomes than the particular therapeutic technique that is used. In both psychotherapy and medication treatments for depression, it appears that the more patients perceived their doctors as caring, empathic, open, and sincere, the greater their symptom improvement. There is also good evidence that psychotherapy is as effective and antidepressants for mild to moderate depression, and that antidepressants are slightly superior for chronic depression. However, even the latter should be interpreted carefully and within the context that patients prefer psychotherapy, their adherence to medications is poorer, side effects are worse for medications, and drop out rates are lower for psychotherapy.
Practice Implications
Patients benefit from antidepressant medications, but perhaps not exactly for the reasons that they are told. Psychosocial factors likely account for a large proportion of the effects of many medically-based interventions for mental disorders. Psychosocial factors are actively used in many psychotherapies, and therapists’ qualities like their ability to establish an alliance, empathy, and professionalism account for a moderate to large proportion of why patients get better.

Therapists Affect Patient Dropout and Deterioration
Saxon, D., Barkham, M., Foster, A., & Parry, G. (2016). The contribution of therapist effects to patient dropout and deterioration in the psychological therapies. Clinical Psychology and Psychotherapy. Advanced online publication, DOI: 10.1002/cpp.2028.
Outcomes for patients receiving psychotherapy are generally positive, but not always. For example, patients might drop out of therapy (i.e., unilaterally end therapy). In clinical trials, the average drop out rate is somewhere between 17% and 26% of patients. Also, patients might deteriorate during therapy (i.e., show a reliable negative change in symptoms from pre- to post-therapy). On average, about 8.2% of patients show a reliable deterioration after therapy. In this large study from a practice-based research network in the UK, Saxon and colleagues were interested in estimating the effect that therapists had on patient drop out and deterioration. Therapist effects refer to differences between therapists and the effects of this difference on patient outcomes. The authors were also interested in whether therapist effects predicted negative outcomes after controlling for therapist case-mix (i.e., patient variables like severity of symptoms, risk of self harm). Their study included 85 therapists who treated more than 10,000 adult patients over a 10-year period. Each therapist saw between 30 and 468 patients at one of 14 sites in the UK. About half of patients had moderate to severe depressive symptoms, and/or moderate to severe anxiety symptoms prior to starting therapy. Outcomes were measured with a reliable and valid psychometric instrument at pre- and post-treatment. The proportion of patients who dropped out of therapy was 33.8%. Patients who dropped out attended an average of 2.8 sessions (SD = 1.91), whereas treatment completers attended an average of 6.1 sessions (SD = 2.68). About 23.5% of therapists had drop out rates that were significantly worse than average. These below average therapists (n = 13) had 49% of their patients drop out, whereas above average therapists (n = 20) had only 12% of their patients drop out. Most patients who completed therapy improved (72.2%), but about 7.2% of patients deteriorated to some degree. The average therapist (i.e., 74% of therapists) had 4.6% of their patients who got worse, whereas below average therapists (i.e., 4.7% of therapists) had up to 14.9% of their patients who got worse. That is, almost 3 times as many patients deteriorated with below average therapists.
Practice Implications
We know from previous studies that the type and amount of therapist training or theoretical orientation are not predictive of patient outcomes. However, previous research does suggest that therapists’ lack of empathy, negative countertransference, over-use of transference interpretations, and disagreement with patients about therapy process was associated with negative outcomes. Patient safety concerns might necessitate below average therapists to be identified and provided with greater support, supervision, and training.

How Important are the Common Factors in Psychotherapy?
Wampold, B. E. (2015). How important are the common factors in psychotherapy? An update. World Psychiatry, 14, 270-277.
What is the evidence for the common factors in psychotherapy and how important are they to patient outcomes? In their landmark book, The Great Psychotherapy Debate, Wampold and Imel cover this ground is some detail, and I reviewed a number of the issues raised in their book in the PPRNet blog over the past year. This article by Wampold provides a condensed summary of the research evidence for the common factors in psychotherapy, including: therapeutic alliance, therapist empathy, client expectations, cultural adaptation of treatments, and therapist effects. Therapeutic alliance refers to therapist and client agreement on tasks and goals of therapy, and the bond between therapist and client. A meta-analysis of the therapeutic alliance included over 200 studies of 14,000 patients and found a medium effect of alliance on patient outcomes (d = .57) across a variety of disorders and therapeutic orientations. A number of studies are also concluding that the alliance consistently predicts good outcomes, but that early good outcomes do not consistently predict a subsequent higher alliance. Further, therapists and not patients were primarily responsible for the alliance-outcome relationship. Another common factor, empathy, is thought to be necessary for cooperation, goal sharing, and social interactions. A meta-analysis of therapist empathy that included 59 studies and over 3,500 patients found that the relationship between empathy and patient outcome was moderately large (d = .63). Patient expectations that they will receive benefit from a structured therapy that explains their symptoms can be quite powerful in increasing hope for relief. A meta-analysis of 46 studies found a small but statistically significant relationship (d = .24) between client expectations and outcome. Cultural adaptation of treatments refers to providing an explanation of the symptoms and treatment that are acceptable to the client in the context of their culture. A meta analysis of 21 studies found that cultural adaptation of evidence-based treatments by using an explanation congruent with the client’s culture was more effective than unadapted evidence-based treatments, and the effect was modest (d = .32). Finally, therapist effects, refers to some therapists consistently achieving better outcomes than other therapists regardless of the patients’ characteristics or treatments delivered. A meta analysis of 17 studies of therapist effects in naturalistic settings found a moderately large effect of therapist differences (d = .55).
Practice Implications
These common factors of psychotherapy appear to be more important to patient outcomes than therapist adherence to a specific protocol and therapist competence in delivering the protocol. As Wampold argues, therapist competence should be redefined as the therapist’s ability to form stronger alliances across a variety of patients. Effective therapists tend to have certain qualities, including: a higher level of facilitative interpersonal skills, a tendency to express more professional self doubt, and they engage in more time outside of therapy practicing various psychotherapy skills.

The Effect of Therapist Empathy on Client Outcomes
Elliott, R., Bohart, A. C., Watson, J. C., & Greenberg, L. S. (2011). Empathy. Psychotherapy, 48(1), 43.
There has been a recent upsurge in interest in empathy in psychotherapy following scientific studies in the field of social neuroscience. This research has focused on activation in areas of the brain associated with emotional stimulation, perspective taking, and emotion regulation. Conceptualizations of the role of empathy in psychotherapy have a rich history in both client-centered and psychodynamic traditions. Carl Rogers defined empathy in part as “...the therapist’s sensitive ability and willingness to understand the client...from the client’s point of view.” Elliott and colleagues indicate three main modes of expressing therapeutic empathy: empathic rapport (compassionate understanding of the client’s experience); communicative attunement (ongoing effort to stay attuned with the client’s experience); and person empathy (experience-near understanding of the client’s world). In this meta-analysis of research on therapeutic empathy, Elliott and colleagues were interested in the strength of the relationship between therapist empathy and client outcome, and factors that might determine this relationship. Their meta analysis included 57 different studies of 3,599 clients. The relationship between therapist empathy and client outcome was medium-sized (r = .31), and in the same order of magnitude as the alliance-outcome relationship. There were no differences between theoretical orientations in the size of the empathy-outcome relationship – in other words, empathy was equally important across types of therapy. Client measures of therapist empathy had the largest relationship to client outcome, whereas therapist ratings of empathy had the smallest association with client outcomes. In other words, if you are interested in therapist empathy, best to ask the client. Also, the empathy-outcome relationship was larger for less experienced (vs more experienced) therapists and for more severely (vs less severely) distressed clients. That is, empathy likely is most important for newer therapists and more distressed clients.
Practice Implications
Therapist empathy is essential to any psychotherapy regardless of orientation. Empathic attunement and expression is particularly important for clients of newer therapists, and for more distressed clients. Elliott and colleagues suggest that the empathic therapist’s primary goal is to understand the client’s experience and to communicate this understanding to the client. This can be done through: empathic affirmations (i.e., validating the client’s perspective); empathic evocations (bringing the client’s experience to life with rich, evocative, and concrete language); and empathic conjectures (making explicit what is implicit in the client’s narrative). Empathy can deepen client’s experiences, but therapeutic empathy also involves individualizing responses to the client. For example, some fragile patients may find typical expressions of empathy as too intrusive, whereas other clients may find therapeutic empathy to be too directive or too foreign. Being attuned to the client’s receptiveness to empathy is an important therapeutic skill. Elliott and colleagues emphasize that empathy should be grounded in authentic caring for the client and as part of a healthy therapeutic relationship.

Clients and Therapists Differ in Their Perceptions of Psychotherapy.
Handbook of Psychotherapy and Behavior Change: Starting in March 2013 I will review one chapter a month from the Handbook of Psychotherapy and Behavior Change in addition to reviewing psychotherapy research articles. Book chapters have more restrictive copy right rules than journal articles, so I will not provide author email addresses for these chapters. If you are interested, the Handbook table of content and sections of the book can be read on Google Books.
Bohart, A.C. & Wade, A.G. (2013). The client in psychotherapy. In M. Lambert (Ed.) Bergin and Garfield’s handbook of psychotherapy and behavior change (6th ed.), pp. 219-257. Hoboken, NJ: Wiley.
Last month I blogged about the section in Bohart and Wade’s (2013) chapter that focused on client symptom severity and motivation. This month I focus on differences between clients and therapists on their perceptions of therapy processes and outcomes. In a previous blog (see June 2013), I reviewed a meta analysis that showed that given two equally effective treatments, clients should be given their preference in order to improve outcomes. Clearly, client perceptions and preferences are important, and perhaps more important than the therapist’s perceptions. Bohart and Wade (2013) reviewed a number of studies that demonstrated this. For example, studies show that client ratings of the therapeutic alliance predicted which therapists had better than average outcomes, whereas therapist ratings of the alliance did not predict outcomes. In three other meta-analyses, client perceptions of therapist genuineness, empathy, and therapeutic presence were each more predictive of outcomes than the respective therapists’ assessments of their own genuineness, empathy, and therapeutic presence. Clients also value different outcomes compared to therapists and researchers. Most research on outcomes tends to focus on symptom reduction, but clients appear to have a broader view of good outcomes. In a qualitative study, clients focused on healthier relationship patterns, an increase in self-understanding that led to freedom from and avoidance of self-destructive behaviour, and stronger valuing of the self, in addition to symptom reduction. Others report that clients define good outcomes as reengaging in meaningful work and social roles, and restoring their self respect.
Practice Implications
Clients are more finely attuned to the therapeutic alliance than therapists, and perhaps are better at detecting relevant and helpful therapist stances. If you are interested in assessing therapeutic alliance or a therapist’s empathy, don’t ask the therapist, ask the client. This has implications for training therapists in helpful therapeutic relationship stances. Helping trainees find areas for continued development as a therapist (i.e., in terms of improving their empathy, genuineness, and therapeutic presence) may require asking their clients’ opinions. Client perceptions of therapist qualities are more relevant than therapist perceptions when assessing effective therapist relationship stances. Therapists should monitor client preferences, particularly if the client is having difficulty engaging in the therapy. If possible and reasonable, therapists should alter their relationship approach to a client based on client feedback. Regarding outcomes, therapists, researchers, and agencies should consider broader definitions of outcomes that are more aligned with what clients want and value. Improved self concept, improved relationships, and better social and work functioning may be just as important as symptom reduction for most clients.
