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.

The Therapeutic Alliance in Child and Adolescent Psychotherapy
Roest, J.J., Welmers-Van de Poll, M.J., Van der Helm, G.H.P., Stams, G.J.J.M., & Hoeve, M. (2022). A three-level meta-analysis on the alliance-outcome association in child and adolescent psychotherapy. Research on Child and Adolescent Psychopathology.
Much of the research and writing about the therapeutic alliance has focused on adult individual psychotherapy. However, there have been several recent meta-analyses of the alliance-outcome association in child populations. In one meta-analysis of 28 studies, for example, the mean alliance-outcome correlation was r = .19, which represents a small but positive effect. Most of these previous meta-analyses only looked at alliance rated at one time point (usually early in therapy) rather than focusing on the growth in the alliance across sessions. These previous meta-analyses also did not investigate the effect of alliance agreement on treatment outcomes (i.e., whether therapist and child were congruent in their ratings of the alliance). In this meta-analysis by Roest and colleagues, the authors tried to parse out these various factors that might affect the alliance-outcome association in studies of child and adolescent psychotherapy. The authors included 99 studies representing 8,496 children and 3,442 parents. They found that associations between child-therapist alliance and child outcomes (r = .17), growth in child-therapist alliance across sessions and child outcomes (r = .19), and parent-therapist alliance and child outcomes (r = 0.13) tended to be positive but small. However, associations between child-therapist alliance agreement (i.e., their congruence in alliance ratings) and child outcomes (r = .21) and the association between parent-therapist alliance and parent outcomes (r = 0.24) were positive and moderately large.
Practice Implications
It appears that the therapeutic alliance plays a role in positive outcomes for child and adolescent patients. Overall, the effects seem to be small, indicating that developing a good alliance may have a modest effect on a child’s outcomes. A more important effect might be noted in the agreement or congruence between therapist and child or adolescent client on their experience of the alliance. That is, a therapist who is more attuned to their patient’s experience of the therapeutic relationship might promote better outcomes. Attunement might require therapists to accurately reflect on the child’s experience of the relationship and of the therapist. Mentalizing (understanding oneself and others in terms of intentions and mental states) may be a key skill to develop for a therapist who works with children and adolescents.

The Therapeutic Alliance in Treating Posttraumatic Stress Disorder
Howard, R., Berry, K., & Haddock, G. (2021). Therapeutic alliance in psychological therapy for posttraumatic stress disorder: A systematic review and meta-analysis. Clinical Psychology and Psychotherapy.
The therapeutic alliance is a key therapeutic factor with a lot of research support. The alliance is the collaborative agreement between patient and therapist on the goals and tasks of therapy, and their emotional bond. A meta-analysis of 295 studies reported that the alliance is moderately and reliably related to patient outcomes, and that this effect cuts across therapy modalities, orientations, and diagnoses. Some clinical writers expressed concern that the alliance is more difficult to develop with patients with posttraumatic stress disorder (PTSD) because of psychological consequences of PTSD like avoidance, mistrust, emotion regulation problems that pose a barrier to developing an alliance. Further, the disrupted interpersonal relationships that is part of the PTSD experience may also inhibit the development of an alliance with a therapist. However, one could also argue that a strong therapeutic alliance that is characterized by an emotional bond between client and therapist might be highly therapeutic for patients with PTSD. This meta-analysis by Howard and colleagues is the first to systematically review the research on the association between the therapeutic alliance and patient outcomes following PTSD treatment. The meta-analysis included 12 studies of adults receiving treatment for PTSD. The aggregated correlation effect size was r = -.339 (95% CI: -0.436, -0.234) with low levels of heterogeneity among the studies indicating that the findings are reliable. The average effect size was moderate in size, robust to effects of an outlier, and there was little evidence of publication bias. The authors also conducted a sub analysis that indirectly compared in-person therapy (k = 8; r = -.323) to remote therapy (k = 4; r = -.390) in which they found no significant differences (Q(1) = 0.41, p = .524) in the alliance-outcome association.
Practice Implications
The findings add support to the larger research literature in psychotherapy about the importance of the therapeutic alliance to patient outcomes. In particular, the findings suggest that clinicians should develop a good therapeutic alliance when treating patients with PTSD in order to promote better outcomes. That is, therapists and clients must come to a collaborative agreement on what the goals of the therapy are and how the therapy will be conducted. In addition, developing an interpersonal therapeutic bond will help the patient to weather the challenges that are associated some PTSD treatments. The findings also suggested that the effect of the alliance was as strong when therapy was in-person versus remote – but this finding is not as reliable given the indirect nature of the comparisons.

Therapists Are Mostly Responsible for the Therapeutic Alliance
Del Re, A. C., Flückiger, C., Horvath, A. O., & Wampold, B. E. (2021). Examining therapist effects in the alliance–outcome relationship: A multilevel meta-analysis. Journal of Consulting and Clinical Psychology. Advance online publication.
The therapeutic alliance has been consistently found to be a reliable predictor of patient outcomes. The alliance in therapy refers to the patient and therapist collaborative agreement on the tasks of therapy and the goals of therapy, as well as their emotional bond. Previous research suggested that the therapist contribution to the alliance accounted for a significant proportion of patient outcomes. That is, some therapists are better than others at forming a good alliance across a variety of patients, and those therapists who can form a good alliance have patients that achieve better outcomes. If therapists are responsible for most of the effects of a positive therapeutic alliance, then efforts should be directed toward training therapists to improve the alliance. In this meta-analysis of 152 studies, Del Re and colleagues used Patient-Therapist Ratio (PTR) as a proxy to estimate the contribution of the therapist to the alliance. Large PTR refers to many patients per therapist, whereas a low PTR refers to few patients per therapist. A significant effect of low PTR on the alliance – outcome relationship would indicate that most of the effect of the alliance on outcomes was due to the therapist. The overall effect of the alliance on patient outcomes was moderately large (r = .275, 95% CI = .247, .302) and similar to what was found in previous research. In other words, a higher therapeutic alliance between patient and therapist was related to better patient outcomes. PTR was a significant moderator of the alliance – outcome relationship (ß = −0.006, 95% CI = −0.010, −0.002). That is, the therapist had a significant contribution to the alliance – outcome association. There was no evidence of publication bias in the research, and other potential confounds did not significantly reduced the effect of the therapist on the alliance and outcomes.
Practice Implications
The strength of the relationship of the therapeutic alliance to patient outcomes is mostly due to the therapist’s characteristics or actions. That is, therapists are largely responsible for the therapeutic alliance and its impact on patient outcomes. Previous research suggested that more effective therapists have the interpersonal skills to manage interpersonally challenging situations. More effective therapist interpersonal skills include: verbal fluency, instilling hope, persuasiveness, emotional expression, warmth, empathy, and the capacity to repair alliance ruptures. Therapists who are capable of engaging in these facilitative interpersonal behaviors across a range of patients are more likely to achieve outcomes for their patients.

Therapeutic Alliance Predicts Patient Outcomes Over and Above Other Factors
Flückiger, C., Del Re, A. C., Wlodasch, D., Horvath, A. O., Solomonov, N., & Wampold, B. E. (2020, March 26). Assessing the alliance–outcome association adjusted for patient characteristics and treatment processes: A meta-analytic summary of direct comparisons. Journal of Counseling Psychology. Advance online publication.
The therapeutic alliance is probably the most researched concept in psychotherapy. The alliance refers to a collaborative agreement on the tasks of therapy (what patients and therapists do in therapy, like homework, or examine the past or relationship issues), a collaborative agreement on the goals of therapy (what the desired outcomes might be), and the relational bond between patient and therapist (liking and respect for one another). The most recent meta-analysis of the alliance included 296 studies. The meta-analysis showed a moderate and robust relationship between higher alliance and better patient outcomes regardless of type of therapy, who rated the alliance, or how it was rated. Nevertheless, some still think that the alliance is a byproduct of other factors like patient symptom severity (less symptomatic patients may report a better alliance with therapists) or adherence to treatment manuals (higher therapist adherence may lead to a better alliance). In other words, some argue that the alliance may not directly affect outcomes and may not be that important. In this meta-analysis, Fluckiger and colleagues examined 60 studies with over 6,000 patients that reported the alliance-outcome relationship, and also the effects of patient characteristics like symptom severity and adherence to treatment manuals. Overall, the therapeutic alliance was significantly related to patient outcomes, r = .304 (95% CI [.253, .354], p < .001, k = 53). When the authors of the primary studies controlled for patient characteristics like symptom severity, the adjusted alliance - outcome correlation remained significant, r = .286 (95% CI [.226, .344], p = .001, k = 35). When the authors of primary studies controlled for the effects of therapist adherence to a treatment manual, the adjusted alliance – outcome correlation still remained significant, r = .242 (95% CI [.179, .306], p = .001, k = 13). The slight reduction in the alliance-outcome correlation caused by the effects of patient symptom severity or therapist adherence to a manual was not significant.
Practice Implications
Therapists’ capacity to develop a therapeutic alliance is a key factor to patients experiencing a good outcome from psychotherapy. This is true for many types of patients with differing levels of symptom severity, and also true regardless of type of therapy or level of therapist adherence to a treatment protocol. Developing shared treatment goals and agreeing on the tasks of therapy are important first steps. In addition, therapists and clients who like working together and share a sense of mutual respect are more likely to experience a successful therapy. Maintaining the alliance throughout therapy is also important. The alliance fluctuates across time indicating subtle or obvious ruptures or tensions that occur. Therapists’ skills at identifying and repairing alliance ruptures is critical to an ongoing collaborative relationship and to patients achieving the best possible outcomes.

The Reciprocal Relationship Between the Alliance and Outcomes
Flückiger, C., Rubel, J., Del Re, A. C., Horvath, A. O., Wampold, B. E., Crits-Christoph, P., Atzil-Slonim, D., . . . Barber, J. P. (2020). The reciprocal relationship between alliance and early treatment symptoms: A two-stage individual participant data meta-analysis. Journal of Consulting and Clinical Psychology, 88(9), 829–843.
The therapeutic alliance (patient and therapist agreement on tasks and goals of therapy and their emotional bond) is the most researched concept in psychotherapy. The research clearly indicates that a positive alliance reliably predicts patient outcomes in terms of reduced symptoms. However, researchers still debate whether the alliance is at all necessary. That is, some argue that the alliance is the result of patients feeling better early in therapy, and so the alliance is only an outcome of early symptom reduction. If that is the case, then the alliance is an artifact of symptom reduction, and clinicians need not pay much attention to it. In this meta-analysis, Fluckiger and colleagues collected 17 studies representing over 5000 patients that evaluated whether alliance in a previous session predicted outcomes in a subsequent therapy session, and vice versa. In other words, they looked at all studies that evaluated if change in alliance preceded change in symptoms and if change in symptoms preceded change in the alliance. What is unique about this meta-analysis is that they gathered patient-level data from the original studies. That allowed them to test the therapeutic alliance theory for each individual patient on a session by session basis for the first 7 sessions of therapy. (For the stats geeks out there, the authors analysed within-person [between-session] effects using multilevel time-lagged models). Their analyses found that high alliance at a preceding session was related to lower symptoms at the subsequent session (B adjusted = -.065 (95% CI [-.092, -.038]; p < .0001)), and higher symptoms at the start of a session was related to lower post session alliance (B adjusted = -.148 (95% CI [-.215, -.081]; p < .0001). They also found that patients who generally reported high alliance scores showed a stronger alliance – outcome relationship, and those with greater symptoms had a weaker alliance - outcome relationship.
Practice Implications
This meta-analysis is another indication of the importance of therapists and patients coming to a collaborative agreement on the tasks of therapy (what is done during sessions) and the goals of therapy (what issues to work on), and of their relational bond. The alliance is not always easy to establish – especially with regard to agreeing on goals. Also, the alliance should not be forgotten once established – alliance ruptures or tensions occur frequently and can have a negative effect on patients’ mental health outcomes. Patients of psychotherapists who repair alliance tensions generally have better mental health outcomes.

Is the Therapeutic Alliance Diminished by Videoconferencing Psychotherapy?
The working alliance is the collaboration between client and therapist on the tasks and goals of therapy, and it also includes the emotional bond. The alliance is the most researched concept in psychotherapy, and it is reliably related to good client outcomes. However, the alliance has been rarely studied in the context of videoconferencing psychotherapy (VCP). Delivering psychotherapy remotely was already gaining popularity prior to COVID-19 because of its potential to improve access to mental health care especially for people who live in remote areas. Some argue that face to face therapy might result in a higher therapeutic alliance because of the rich interpersonal cues, like eye contact and body posture that may facilitate collaboration and the bond. There is emerging evidence that VCP can be effective and that it may have comparable outcomes to face-to-face therapy. But what about the working alliance – does it develop in VCP similarly to face to face therapy? In this meta-analysis, Norwood and colleagues conducted a systematic review of the existing research on the working alliance in VCP. They found only 4 direct comparison randomized controlled studies on the topic, and on average VCP resulted in a lower working alliance compared to face to face therapy, but the difference was not statistically significant (n = 4; SMD = -0.30; 95% CI: -0.67, 0.07; p = 0.11). People who received treatment via VCP had similar levels of symptom reduction compared to those who received face to face therapy (n = 4; SMD = −0.03; 95% CI [−0.45, 0.40], p = 0.90).
Practice Implications
With only four direct comparison randomized trials to draw from, the results of this meta-analysis remained ambiguous with regard to the therapeutic alliance. Although the difference between VCP and face to face therapy was not statistically significant, it was not ignorable – an effect size of SMD = -0.30 suggests a small advantage for face to face therapy when it comes to the alliance. However, symptom outcomes were comparable between face to face and VCP. The results suggest that therapists who use VCP during a pandemic, must pay particular attention to developing and maintaining a therapeutic alliance by collaboratively agreeing on goals and tasks of therapy, and by focusing on establishing an affective bond with patients despite the limited nonverbal cues available with online psychotherapy.
