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 the treatment of depression, the effects of role induction in psychotherapy, and negative experiences in psychotherapy from clients’ perspective.

Therapists’ Appropriate Responsiveness to Clients
Stiles, W. B. & Horvath, A. O. (2017). Appropriate responsiveness as a contribution to therapist effects. In L. Castonguay and C. Hill (Eds.). How and why some therapists are better than others?: Understanding therapist effects (Ch. 4). Washington: American Psychological Association.
Appropriate responsiveness refers to therapists’ ability to adapt their techniques to the client’s requirements and circumstances. This might include planning treatment based on how the client is responding, using the client’s evolving responses to treatment as a guide to interventions, and adjusting interventions already in progress in light of subtle signs of client uptake. Appropriate responsiveness may depend on a client’s diagnosis, education, personality, stage of life, values, stage of therapy, among others. Responsiveness also depends on therapists’ skills, personality, theoretical orientation, and history of the therapeutic relationship. In this chapter, Stiles and Horvath review the literature on relationship variables that predict therapy outcomes and interpret these findings in the context of therapist responsiveness. To illustrate, previous research showed that therapists’ rigid adherence to a treatment manual was associated with worse client outcomes – or to state it differently, therapist adherence flexibility was associated with better outcomes. This flexibility is an indication of appropriate responsiveness on the part of the therapist. Stiles and Horvath also argue that most of the relationship variables that predict client outcomes reflect whether therapists appropriately respond to the circumstances of the client at a particular point in therapy. That is, evidence-based relationship factors like alliance, cohesion, empathy, goal consensus, positive regard, and others evaluate whether the therapist successfully tailored interventions and behaviors to the client’s unique personality and circumstances. For example, therapeutic alliance (the affective bond, and agreement on tasks and goals of therapy) indicates that the therapist selected interventions that were appropriate to the client, introduced them at the right time, and was attentive to and interested in the client’s progress. In support of this, the authors cite research showing that the therapeutic alliance is largely a function of the therapists’ responsiveness and not the client’s characteristics. That is, therapists are largely responsible for the quality of the therapeutic alliance.
Practice Implications
Research is increasingly indicating that therapists’ ability to respond appropriately to clients on a moment-to-moment basis is a key therapeutic factor. In other words, therapists who can build strong alliances, repair alliance ruptures, work for goal consensus and collaboration, manage countertransference, and be empathic are those who respond to the changing nature of client characteristics and needs in therapy. Supervision that provides feedback to therapists on these therapeutic factors, mastering a framework to guide interventions, client progress monitoring and feedback, and acquiring knowledge of client personality and cultural factors can sensitise therapists to their client’s changing requirements and allow them to respond therapeutically.

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.

Long-Term Medical Conditions Reduce Outcomes in Psychotherapy
Dalgadilo, J., Dawson, A., Gilbody, S., & Bohnke, J.R. (2017). Impact of long-term medical conditions on the outcomes of psychological therapy for depression and anxiety. British Journal of Psychiatry, 210, 47-53.
Twenty percent of people have long-term medical conditions, and this percentage rises to 58% for people over 60. These long-term conditions account for approximately 70% of health care costs in the UK. The most prevalent long-term conditions in the population include: hypertension, chronic pain, gastrointestinal disorders, asthma, diabetes, heart disease, and chronic obstructive pulmonary disease. Do these conditions reduce the outcomes of psychological therapies? Dalgadilo and colleagues conducted a large study in the UK of patients who accessed publicly funded psychological services. The authors looked at what impact long-medical problems had on psychological intervention outcomes. Patients accessing the public system in the UK received stepped care - so that they were first given self help followed by a second step of intensive psychotherapy, if they needed it. The sample for the study included over 28,000 patients with a mean age of just over 38 years. About 23.2% had a long-term condition. Sixty-eight percent only received the low intensity self help, and 32% required the intensive psychotherapy. Those with long-term conditions, compared to those without long-term conditions, tended to report higher levels of distress and lower quality of life at the outset. Long-term conditions that were associated with poorer psychological intervention outcomes included: chronic pain, chronic obstructive pulmonary disorder, severe mental health problems, and diabetes. The effects were small (d = .20) to medium (d = .50) sized (confidence intervals not reported). Those with long-term conditions were more likely to receive high intensity psychotherapy after the self help. However, poorer outcomes for those with long-term conditions, compared to those without long-term conditions, were still apparent after they received the intensive psychotherapy.
Practice Implications
Compared to those without long-term medical conditions, those with long-term conditions have a higher level of impairment to start with and tend to finish therapy with greater depression and anxiety. The study points to the need to integrate psychological therapies in medical practices - especially for those with long-term medical conditions. Certain conditions like chronic pain, and having multiple conditions increase psychological distress and likely reduce patient mental health outcomes.
Does Continuation of Anti-Depressant Medication Reduce Relapse?
Gueorguieva, R., Chekroud, A.M., & Krystal, J.H. (2017). Trajectories of relapse in randomised, placebo-controlled trials of treatment discontinuation in major depressive disorder: An individual patient-level data meta-analysis. Lancet Psychiatry.
Individuals with a history of depression who get better have a 30% to 50% chance of relapse in the first year. That is, major depression tends to take a recurrent course, so that about a third to half of patients who initially improve will then experience a re-emergence of symptoms. In this meta-analysis, Gueorguieva and colleagues looked at whether they could identify classes of patients who respond differently to antidepressant medications depending on whether they discontinued or continued with the medications after symptoms improved. The meta-analysis included over 1,400 patients from four studies of duloxetine or fluoxetine (i.e., Cymbalta or Prozac) who participated in a discontinuation trial. A discontinuation trial design involves randomly assigning patients who respond positively to the medication either (1) to stay on the effective medication or (2) to discontinue the treatment and receive a placebo. Such a design gives us an estimate of the advantage of maintenance versus discontinuation of medications to reduce relapse of depression in the longer term. Gueorguieva and colleagues found that 33% of those in the medication continuation condition relapsed (i.e., 33% those who responded well to the initial trial of medications and who then continued with medications had a recurrence of depressive symptoms). By contrast, 46% of those in the placebo/medication discontinuation condition relapsed (i.e., 46% of those who responded well to the initial trial of medications and who then received a placebo had a recurrence of depressive symptoms). In other words, continuation of antidepressant medications resulted in a small 13% reduction in relapse rates compared to continuation with a placebo.
Practice Implications
This meta analysis indicates that continuing with antidepressant medications after depressive symptoms remit provides only a modest level of protection against a relapse of depression. Thus continuation with antidepressants after symptoms improve may not be worth it for patients who struggle with medication side effects and complications, or who cannot afford continuation of the medications. There is growing evidence that psychotherapy is effective for preventing relapse, likely because psychotherapy teaches patients ways of coping and interacting with others that allows them to manage life stresses more effectively after the treatment is over.
