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...

Does it Matter Which Therapist a Client Gets?
Barkham, M., Lutz, W., Lambert, M., & Saxon, D. (2017). Therapist effects, effective therapists, and the law of variability. In L.G. Castonguay and C.E. Hill (Eds.) How and why are some therapists better than others? Understanding therapist effects. Washington, DC: American Psychological Association.
Psychotherapy research has often focused on the differences between treatment types (CBT, interpersonal psychotherapy, psychodynamic therapy), which has overshadowed research on what makes for an effective therapist. Psychotherapists represent the most costly important component of psychotherapy, and only recently has research begun to catch up to the importance of therapist effects. The term “therapist effects” refers to differences between therapists (i.e., variability) in their clients’ outcomes. In this chapter, Barkham and colleagues review some of the research on effective therapists. Best estimates of therapist effects suggest that differences between therapists account for about 8% of client outcomes – which is considered a medium effect and larger than the variance accounted for by the type of therapy that a client receives. Psychotherapy research often tries to control for therapist effects by training therapists to adhere to a manual, however adherence to a manual does not substantially reduce therapist effects, and adherence is not related to patient outcomes. The implication is that which therapist a client sees matters to the client’s mental health outcomes. The best research on the topic indicates that about 20% of therapists are substantially better than the average therapist, and 20% are substantially worse than the average. (The good news is that 60% of therapists [the average] are equally and positively effective). In that study of 119 therapists, the least effective therapists had about 40% of their clients recover, whereas the most effective therapists had about 76% of their clients recover. In other words, the better therapists were almost twice as effective as the worse therapists. In a re-examination of previous data, Barkham and colleagues looked at whether other variables, like client symptom severity, played a role in therapist effects. They found that differences among therapists was higher as client baseline severity increased. That is, the gap between better and worse therapists increased when client symptoms were more severe and complex. Good therapists were better equipped to handle more complex cases.
Practice Implications
There are important differences between therapists in their effectiveness, and this makes a difference to clients. It is particularly important for clients with more severe symptoms to be matched with more effective therapists. Previous research indicates that the level of therapist interpersonal skills (alliance, empathy, warmth, emotional expression, verbal skills) can account for significant proportion of therapist effects, and so training therapists in these interpersonal skills will improve client outcomes. Also, therapists who receive continuous reliable feedback throughout therapy about their client’s symptom levels can also drastically reduce client drop-outs and the number of clients who get worse during treatment.

What Characterizes Effective Therapists?
Wampold, B. E., Baldwin, S. A., Holtforth, M. G., & Imel, Z. E. (2017). What characterizes effective therapists. In L.G. Castonguay and C.E. Hill (Eds.) How and why are some therapists better than others? Understanding therapist effects. Washington, DC: American Psychological Association.
The research on therapist effects indicates that some therapists are more effective than others. Previous research showed that therapist characteristics like age, race, ethnicity, gender, and experience are not consistently related to patient outcomes. Neither is therapist competence and adherence to a treatment approach. In this chapter, Wampold and colleagues ask the question: what characterizes effective therapists? The research is complicated because it is difficult to disentangle therapist effects from patient factors. That is, it is possible that some clients (i.e., those who are more motivated, likeable, and psychologically minded) might create favorable conditions for some therapists to be more effective. However, recent advances in statistical methods have allowed researchers to isolate the effects of therapist characteristics from patient factors. Based on this new research, Wampold and colleagues identified four characteristics of effective therapists. (1) The ability to form an alliance across a range of patients. The therapeutic alliance is defined as the agreement on tasks and goals of therapy, and the affective bond between therapist and patient. Alliance is reliably associated with good patient outcomes. Research shows that therapists and not clients are primarily responsible for the alliance-outcome relationship. (2) Facilitative interpersonal skills – which includes verbal fluency, warmth, empathy, and emotional expression. These skills in a therapist are a strong predictor of patient outcomes. (3) Professional self doubt – or healthy skepticism about one’s abilities and skills leading to self-reflective practice has also been found to predict positive patient outcome. (4) Deliberate practice - defined as individualized training activities especially designed to improve specific aspects of an individual’s performance through repetition and successive refinement. The amount of time outside of therapy that therapists engage in improving targeted therapeutic skills predicted patient outcomes.
Practice Implications
Some therapists are better than others - and demographics, professional affiliation, training, and adherence to a manual do not differentiate better therapists. Four factors are emerging as indicators of better therapists. Ability to develop, maintain, and repair a therapeutic alliance is well known to predict patient outcomes and it appears that therapists are largely responsible for the condition of the alliance. Therapists’ ability to be verbal, warm, and empathic is also key to patient outcomes. Professional skepticism about one’s abilities that lead to reflective practice is also an important characteristic in order to continually improve one’s abilities and monitor one’s outcomes. And, finally therapists who spend time outside of therapy deliberately and repetitively practicing skills will achieve better patient outcomes.

What is the Therapist’s Contribution to Patient Drop-out?
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, DOI: 10.1002/cpp.2028.
Sometimes patients experience negative outcomes in psychotherapy. For example, some patients drop out of therapy (i.e., they unilaterally decide to leave therapy before making any progress or before the endpoint planned with the therapist). In a previous meta-analysis of 669 studies, dropout rates ranged from 17% to 26% in psychotherapy trials. In this study, Saxon and colleagues were interested in the therapist effect on drop out. In other words, what is the impact of the individual therapist on negative outcomes like patients unilaterally terminating treatment? To examine the therapist effect one can look at differences between therapists in the average number of patients who drop out within their caseload. The authors looked at over 10,000 patients seen by 85 therapists from 14 sites in the United Kingdom initiative for Improving Access to Psychological Therapies. Therapists were selected if they saw more than 30 patients, and patients were included if they attended more than one session of therapy. Patient mean age was 40.3 (SD = 13.0), 71.2% were women, most were White (95%) and employed (76%). Of all the patients, 76.8% had some level of depression and 82.7% had some level of anxiety. Over 90% of the patients scored in the clinical range for symptom severity at pre-treatment. Patient symptom severity seen by a particular therapist was controlled in this study so that therapists who tended to treat severe cases were not penalized (i.e., case mix was controlled). Patients who dropped out represented 33.8% of the sample, with over half of these patients unilaterally terminating before the third session. The mean number of sessions for treatment completers was 6.1 (SD = 2.68). Therapist differences (i.e., the therapist effect) accounted for 12.6% (CI = 9.1, 17.4) of the patient drop out variance. In other words, about a quarter of therapists had a significantly greater number of drop outs compared to the average therapist. The mean dropout rate for the average therapist was 29.7% (SD = 6.4), the mean dropout rate for the above average therapist was 12.0% (SD = 7.3), whereas the mean dropout rate for the below average therapist was 49.0% (SD = 10.4).
Practice Implications
Who a patient gets as a therapist appears to have an important impact on whether the patient remains in therapy. Almost half of clients dropped out if they saw a poorly performing therapist (and nearly a quarter of therapists were poorly performing). By contrast, highly performing therapists only had a 12% drop out rate. Therapist variables that are known to be related to negative outcomes like dropping out include: lack of empathy, negative countertransference, and disagreements with patients about the therapy process. Previous research showed that therapeutic orientation is not related to negative outcomes. Therapists who are perform below average on when it comes to patient dropout might be able to use progress monitoring or some other means of measuring their patients’ outcomes to their advantage. These therapists may require more support, supervision, or training to improve their patients’ outcomes.

Creating a Climate for Improving Therapist Expertise
Goldberg, S.B., Babins-Wagner, R., Rousmaniere, T., Berzins, S., Hoyt, W.T., Whipple, J.L., Miller, S.D., & Wampold, B.E. (2016). Creating a climate for therapist improvement: A case study of an agency focused on outcomes and deliberate practice. Psychotherapy, 53, 367-375.
There is a lot of evidence that psychotherapy is effective – a result that has been demonstrated in randomized trials and in naturalistic setting. As I have noted numerous times in this Blog, psychotherapy is as effective as medications but without the side effects and with longer lasting results. However, there is room for improvement, especially in the effectiveness of individual therapists. Health care organizations are increasingly interested in quality improvement, which refers to efforts to make changes in practice that will lead to better patient outcomes, better care, and better professional development. One approach to quality improvement in medicine has been through audit and feedback – which involves measuring a clinician’s practice, comparing the clinician’s outcomes to professional standards, and giving the clinician feedback. In psychotherapy, the analogue is routine outcome monitoring in which patient progress is monitored with standardized measures throughout therapy, and therapists receive ongoing feedback on each patient’s progress relative to the average patient with that disorder. We know that therapists tend not to improve in terms of patient outcomes with experience alone, and some authors argue that one of the things that therapists are missing is good quality information about their clients’ progress. What would happen if an agency or organization decided to make it a priority to provide therapists with quality information about client progress? This paper by Goldberg and colleagues is a case study in which an agency deliberately created a culture of quality feedback and professional development to improve therapist expertise, therapist intentional practice, and client outcomes. The case study is of a community mental health agency in Alberta. Over 5,000 clients were seen by 153 therapists over a 7 year period (2008 to 2015) as part of the study. Clients received at least three sessions of therapy (mean = 6.53 sessions, SD = 5.02), and had a range of disorders typically seen in a mental health clinic. Therapists included 49.7% licensed or provisionally licensed professionals at the masters or doctoral level from different professions (e.g., social work, psychology, pastoral counselling), and 50.3% practicum students. Throughout the 7 years of the study, therapists saw an average of 33.52 clients (SD = 26.24). In 2008, the agency required the staff to collect outcome measures of all clients before each session (although patient scores were not tied to staff performance evaluations). This policy change caused a 40% turnover in clinical staff within 4 months (clearly a large minority of therapists did not want to participate in this new clinic directive)! These staff positions were replaced and staffing was stable after that point. In addition to requiring clinicians to provide measures on all patients (although patients could decline to participate), the agency provided monthly clinical consultations with an external consultant as a means of professional development. During these consultation, clinicians were encouraged to bring cases that were not progressing well in order to get feedback on their most challenging patients. Discussions were organized around therapeutic alliance, i.e., clarifying goals and preferences, and ways of facilitating engagement. The overall results showed a significant decline in distress among patients over the course of treatment. Of most interest was that therapists on average showed a significant improvement in their outcomes over time. That is, contrary to research showing that therapists do not improve over time when left to their own devices, therapists in this agency that received feedback and professional education around difficult cases did improve significantly.
Practice Implications
The findings of this study indicate that psychotherapists can improve over time if they receive quality information about client progress, and if they receive professional development that is tied to this information (i.e., concrete suggestions for ways of working with difficult clients). In other words, it is possible for therapist to develop expertise over time under some conditions. A significant challenge in this case study was that a number of therapists left the agency due to the quality improvement efforts. Some therapists are sensitive to or feel threatened by outcome monitoring. However, therapists who remained or who were subsequently hired by the agency showed a reliable increase in their expertise and client outcomes as a result of deliberate intentional practice, quality feedback about client progress, and concrete professional development focused on the therapeutic alliance.

Clients’ Experiences of Psychotherapy
Levitt, H.M., Pomerville, A., & Surace, F.I. (2016). A qualitative meta-analysis examining clients’ experiences in psychotherapy: A new agenda. Psychological Bulletin. Online First Publication, April 28, 2016.
Much of psychotherapy research over the past several decades has focused on therapy outcomes, with the general conclusion that outcomes are equivalent across major psychotherapy orientations. Some of the effects of psychotherapy can be explained by relational factors (e.g., therapeutic alliance). There is also a growing and interesting line of research about therapist variables and therapist effects (see this month’s PPRNet blog on differences between therapists’ outcomes in a large UK sample). Many experts argue that client effects and characteristics account for the largest amount of variance in therapy outcomes. That is, who clients are and what experiences they have are the largest determinants of whether psychotherapy will be helpful. However the client’s experience is often neglected in psychotherapy research reviews. Levitt and colleagues conducted a qualitative meta analysis of qualitative studies of clients’ experiences in psychotherapy. Qualitative research typically involves interviewing clients about their experiences in therapy and coding the transcripts of these interviews. Methods of synthesizing and categorizing themes from client narratives, such as the grounded theory method and thematic analysis, create a rich source of understanding about how clients experience change in psychotherapy. Levitt and colleagues applied qualitative methods to synthesize 109 qualitative studies of over 1400 clients as a way of analysing this research. Six clusters or themes emerged from their qualitative meta analysis: (1) clients experienced therapy as a process of identifying and understanding personal patterns; (2) clients who felt understood and had their experiences validated were able to internalize the therapist’s voice; (3) clients experienced the structure of therapy (spacing of sessions and time allotted to sessions) and therapist expertise as generating credibility for the therapy, but also at times the structure reduced clients’ experience of therapeutic relationship’s authenticity; (4) clients experienced an inherent power differential with therapists that was sometimes compounded by differences in race, gender, and class; (5) clients played a major role in the therapeutic process, and clients felt pleased when they were invited to take the lead; (6) clients’ experiences of being cared-for supported their ability to recognize maladaptive patterns and address unmet vulnerable needs.
Practice Implications
This qualitative meta analysis highlights the important role played by the client’s experience and by the therapy context in promoting good outcomes. The results suggested that better outcomes may be achieved when: (1) therapists encourage clients’ curiosity about their cognitive, emotional and relational patterns; (2) therapists engage in an accepting and caring relationship in order to help clients decrease their defensiveness about vulnerable topics; (3) therapists maintain the therapeutic structure in order to increase clients’ sense of confidence in the process; (4) therapists explicitly acknowledge power differences and repair alliance ruptures; (5) therapists encourage clients to take an active role in therapy as a means of self-healing; and (6) therapists regularly check with clients about the fit of interventions, in-session needs, and treatment goals.
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.
