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...

Progress Feedback Narrow the Gap Between More and Less Effective Therapists
Delgadillo, J., Deisenhofer, A.-K., Probst, T., Shimokawa, K., Lambert, M. J., & Kleinstäuber, M. (2022). Progress feedback narrows the gap between more and less effective therapists: A therapist effects meta-analysis of clinical trials. Journal of Consulting and Clinical Psychology, 90, 559–567.
Some therapists are more effective than others. This is often referred to as the therapist effect. Somewhere between 1% and 29% of patient outcomes can be attributed to which therapist the patient receives. In general, therapists with high facilitative interpersonal skills, high humility, and an ability to withstand difficulties in practice (i.e., ruptures, burnout) may be more clinically effective. To improve outcomes in therapy, some have suggested using routine outcome monitoring and progress feedback. This involves regularly measuring and tracking patient progress with standardized self-report scales throughout treatment and providing the clinician with this information during therapy. Progress feedback allows the therapist to compare their patient’s progress against norms and against the patient’s own progress in preceding sessions. If the patient is not progressing or is deteriorating, then the therapist is alerted to address the issue. Research indicates that progress feedback makes therapy more effective. Less is known about how progress feedback leads to better outcomes. In this meta-analysis, Delgadillo and colleagues assessed the impact of progress feedback on the therapist effect – that is, does progress feedback improve the outcomes of less effective therapists? The meta-analysis was of six clinical trials with data from 4,549 patients and 131 therapists who were randomly assigned to a progress feedback condition or to a control condition without progress feedback. The variability between therapists (ICC = .011) suggested that 1.1% of the overall variance in patient outcomes was due to therapist effects. However, feedback was associated with a significant reduction in the therapist effect (ICC = .009) by 18.2%. A closer look at the data indicated that progress feedback narrowed the gap between more and less effective therapists, such that patients of less effective therapists benefitted the most from their therapist receiving feedback.
Practice Implications
In this meta-analysis conducted on data from controlled studies, there were few under-performing therapists. However, implementing progress feedback was clinically important to achieve better outcomes among some of these therapists. That is, even a single underperforming therapist could attain relatively poor outcomes with dozens or even hundreds of patients. Who the therapist is matters – and some therapists (and their patients) can benefit from supplementing clinical judgement with reliable feedback about patient progress throughout the course of psychotherapy.

Therapist Facilitative Interpersonal Skills
Wampold, B. & Owen, J. (2021). Therapist effects: History, methods, magnitude, and characteristics of effective therapists. In Barkham, W. Lutz, and L.G. Castonguay (Eds.) Bergin and Garfield’s Handbook of Psychotherapy and Behavior Change (7th ed.). Wiley. Chapter 9.
Is therapist interpersonal skill a therapeutic “competence”? Past research on this important topic has been hampered by a couple of methodological challenges. First, asking therapists to self-report on their own social skills and empathy may result in a self-serving bias and is not related to patient outcomes. A second challenge is that therapists’ competence may be influenced by patient characteristics. For example, a therapist seeing an angry patient with low motivation to change might appear less competent than the same therapist seeing an agreeable patient who is highly motivated. Until recently these issues have limited the research on therapist characteristics that indicate therapeutic competence. In this part of the chapter, Wampold and Owen review some of the research that overcomes this limitation. Some researchers conducted a series of studies in which therapists watched videos of standardized patients with different characteristics, and the therapists’ responses to the videos were recorded. In this way, all therapists “saw” the same patients. Therapists’ responses to the videos were coded for facilitative interpersonal skills; that is, for therapist verbal fluency, hope, emotional expression, warmth, empathy, and alliance capacity. In one study, therapist facilitative interpersonal skills assessed with these standardized patient videos predicted outcomes of real patients seen by the therapists in their practices. In another study, student therapists completed the therapist facilitative interpersonal skills assessment at the very beginning of their training. These facilitative skills predicted outcomes obtained when the trainees began seeing patients later in their training. In an interpersonally challenging situation, like some therapeutic encounters where affect is strong, the interpersonal skills of therapists were robust predictors of patient outcome.
Practice Implications
The research showing that therapist interpersonal skills predict patient outcomes is beginning to redefine what it means to be a competent therapist. Research reviewed elsewhere in this blog indicated that adhering to a treatment manual or protocol is not related to patient outcomes. Instead, therapists’ capacity to use verbal skills to express emotions, to be empathic, to develop a therapeutic alliance with a variety of patients, and to repair therapeutic alliance ruptures appear to be much more reliable predictors of patient outcomes. Training programs and professional development should focus on these important skills.

The Therapist Effect: Or Does the Therapist Matter?
Wampold, B. & Owen, J. (2021). Therapist effects: History, methods, magnitude, and characteristics of effective therapists. In Barkham, W. Lutz, and L.G. Castonguay (Eds.) Bergin and Garfield’s Handbook of Psychotherapy and Behavior Change (7th ed.). Wiley. Chapter 9.
The early days of psychotherapy research treated psychotherapists in a clinical trial as largely interchangeable. That is, it was assumed that therapists were more alike than different and so their impact to patient outcomes were ignored. Some of this was thought to be achieved by training therapists to be highly adherent to a treatment protocol. The thinking was that if every therapist followed the manual faithfully, then any differences among therapists would disappear. Never mind that research indicates that therapist adherence to or competence in delivering a manualized treatment is largely unrelated to patient outcomes. In this part of the chapter, Wampold and Owen examine the question of “does the therapist matter to the patient’s outcomes.” In other words, are there differences between therapists when it comes to patient outcomes? It turns out that between 3% and 15% of patient outcomes in highly controlled randomized trials is attributable to differences between therapists. This might seem like a small percentage, but it is larger than outcomes associated with differences between treatment orientations or the effects of specific interventions. And these are highly controlled trials partly designed to reduce therapist differences. In everyday clinical practice in which there is less control over therapists, the lowest estimate of therapist effects is about 6% but could be as high as 12%. The effect of the therapist is probably higher for more severely symptomatic patients.
Practice Implications
Which therapist a patient sees matters, and this is particularly true for patients who have more severe symptoms. That is more severe patients may do much worse or much better in therapy depending on which therapist they see. A therapist’s capacity to follow a treatment manual does not predict patient outcomes, but other factors like interpersonal skills, openness to lifelong learning, and getting reliable feedback about patient outcomes may be those skills and practices that matter to patient outcomes.
Interpersonal Complementarity: Therapist Responsiveness to Patient Interpersonal Behaviors
Constantino, M.J., Boswell, J.F., & Coyne, A.E. (2021). Patient, therapist, and relational factors. In Barkham, W. Lutz, and L.G. Castonguay (Eds.) Bergin and Garfield’s Handbook of Psychotherapy and Behavior Change (7th ed.). Wiley. Chapter 7.
Interpersonal behaviors can be characterized by the level of affiliation (i.e., friendliness vs hostility) and of interdependence (i.e., dominance vs submissiveness). Interpersonal complementarity refers to two people in an interaction whose behaviors are matched on affiliation (friendliness evokes friendliness in the other) and reciprocity in terms of interdependence (dominance evokes submission or submission evokes dominance in the other). So friendly-dominant behaviors in one person tends to evoke friendly-submissive behavior in another and vice versa, and similarly, hostile-dominant behaviors in one person tend to evoke hostile-submission in the other and vice versa. Complementary interactions are comfortable and do not cause anxiety, they reinforce the interactional styles of the participants, and they tend to continue unchanged. Non-complementary interactions do cause anxiety, and they either change or they terminate. In this part of the chapter, Constantino and colleagues review the research on the role of complementarity between therapists and patients. Therapists on average tend to behave in a friendly-dominant style and many but not all patients tend to respond in a friendly-submissive style. The most interesting findings of this line of research is that the number of complementarity interactions between therapists and patients tend to change across stages of successful therapy. In early sessions, patient-therapist interactions tend to be highly complementary. Interactions in the middle of therapy tend to be lower in complementarity. And at the end of therapy, patients and therapists tend to return to higher levels of complementarity. Hostile therapist interactions are rare, and when they occur it is almost exclusively in unsuccessful therapy cases.
Practice Implications
This research has a lot to say about how therapists should respond to patients’ interpersonal behaviors and styles. Therapists should always remain affiliative or friendly (or at least neutral) and avoid hostile interactions with patients. The research indicates even a small number of hostile responses from therapists may lead to negative outcomes or dropping out. The research seems to indicate that (a) higher therapist-patient interpersonal complementarity early in therapy is related to establishing rapport and a therapeutic alliance, (b) lower complementarity in the mid stage of therapy might indicate that therapists are engaging patients differently in order to help change patient patterns of interpersonal relating, and (c) a return to higher complementarity at the end of therapy may indicate therapists reinforcing changes and patients experiencing a new sense of self within the therapeutic relationship.

Emotional Experiences of Psychotherapists
Chui, H., & Liu, F. (2021). Emotional experience of psychotherapists: A latent profile analysis. Psychotherapy, 58(3), 401–413.
Working with client emotional experiences in therapy is a core aspect of the psychotherapist’s work, regardless of their theoretical orientation. And so, therapists’ performance and their own well-being may be impacted by their capacity to experience and regulate their own emotions. Emotional reactivity refers to one’s sensitivity, intensity, and duration of emotional experience. Emotion regulation refers to the capacity to manage and express emotions and may be considered an interpersonal competency for therapists. Such competency likely involves flexible expression of emotion and a capacity for empathy. A better understanding of how therapists experience emotions might inform therapists’ use of empathy to facilitate their work with clients. In this study, Chui and Liu surveyed 314 English speaking and 589 Chinese speaking psychotherapists and asked them about their experiences of emotional reactivity, their emotion regulation, and empathy. Their data allowed them to develop profiles of psychotherapists along dimensions of emotional experience. Three latent profiles emerged in both the English and Chinese speaking samples of therapists. The highest proportion of English-speaking therapists (58%) were categorized as “Calm Regulators”, which indicated therapists with low emotional reactivity and few problems with emotion regulation. Next, 34.4% of English-speaking therapists were characterized as “Moderate Experiencers”, and 7.6% were “Emotional Feelers”. The latter profile included therapists who were emotionally over-reactive and who had greatest difficulty with regulating their emotions. As one might expect, those with the Calm Regulator profile had higher capacity for perspective taking, higher empathic concern, and lower personal distress than therapists in the other profiles. Also, therapists who were older, with more education, female, and with a psychodynamic orientation were more likely to have the Calm Regulator profile. Results were remarkably similar in the Chinese speaking sample, in which Calm Regulators also reported higher levels of counsellor self-efficacy.
Practice Implications
Therapists with the “Emotional Feelers” profile (i.e., that have higher levels of emotional reactivity and more difficulty regulating their emotions) may be at higher risk of burnout and of being less effective in their work. As a profession we often discuss clients’ individual differences in emotional experience and emotion regulation, but we spend less time considering these important interpersonal competencies in therapists. Recent surveys suggest that almost 50% of therapists may be at high risk of mental health problems. Psychotherapists, trainers, and supervisors need to pay more attention to therapists’ capacity to regulate their emotions, and its impact on their capacity to be emotionally flexible and empathic with clients. Therapists might consider personal therapy as a means of building this capacity.

Psychotherapist burnout affects patient outcomes
Delgadillo, J., Saxon, D., & Barkham, M. (2018). Associations between therapists’ occupational burnout and their patients’ depression and anxiety treatment outcomes. Depression and Anxiety, 35, 844-850.
Providing psychotherapy can be challenging for the therapist. Vicarious trauma, secondary traumatic stress, and compassion fatigue among psychotherapists are well documented. In addition, organizational conditions in publicly funded mental health programs like workload, safety issues, and lack of supervision and support can lead to higher rates of therapist burnout. Surveys document that between 21% and 67% of mental health workers experience burnout. Occupational burnout can take many forms, but it is typically defined as emotional exhaustion and disengagement that lead to lower levels of therapist empathy, engagement, and depersonalization. One could speculate that burnout among therapists leads to worse patient outcomes because of the impact of disengagement on the therapeutic alliance. However few if any studies examined the association between therapist burnout and patient mental health outcomes. In this study, Dalgillo and colleagues assessed therapist burnout and job satisfaction in 49 therapists, and they assessed depression and anxiety outcomes in 2223 of their patients. The therapists provided treatment as part of the UK’s Increasing Access to Psychotherapy (IAPT) program. The analyses controlled for therapist case mix. That means that differences between therapists’ caseload (patient level of impairment, social economic status, and severity of symptoms) were controlled so that the findings were unique to the effect of therapist burnout and job satisfaction on patient mental health outcomes. Higher therapist disengagement (an index of burnout) and lower therapist job satisfaction were significantly associated with poorer treatment outcomes for patients. In addition, higher burnout was related to lower job satisfaction among therapists.
Practice Implications
This is one of the first studies to show a direct association between therapist burnout and low job satisfaction with patient mental health outcomes. It is possible that these findings are specific to the UK’s IAPT program, in which therapists might feel a lower sense of control over their work. Nevertheless, organizations need to design mental health delivery in such a manner as to enhance psychotherapist autonomy, coping, and resilience, as these are likely related to therapist burnout and poorer patient mental health outcomes.
