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...

Adapting Therapy to Each Client: Becoming an Evidence-Based Therapist I
Norcross, J.C. & Wampold, B.E. (2018). A new therapy for each patient: Evidence‐based relationships and responsiveness. Journal of Clinical Psychology, Online First, DOI: 10.1002/jclp.22678
Over the next several months, I will review in this blog results of a number of meta-analyses conducted recently on patient factors and relationship factors in psychotherapy. These factors provide evidence-based guidance to psychotherapists on how best to relate to and adapt to clients so that psychotherapy is more effective. This introductory article by Norcross and Wampold is an overview of the nine meta analyses related to transdiagnostic client factors to which therapists can adapt their interpersonal stances and treatment. The goal is to enhance treatment effectiveness by therapists tailoring therapy to individual client characteristics that are related to outcomes. Decades of research indicate that client transdiagnostic characteristics have more influence on outcomes than the particular treatment method, and likely more influence than the particular client diagnosis. The research indicates that giving the identical treatment to every client without adaptation to client characteristics is not an effective approach to providing psychotherapy. These meta analyses of client factors indicate that therapists should select different interventions and relational stances according to the client and the context. What are these client characteristics and therapist adaptations that are reliably related to outcomes? The client factors most strongly related to outcomes include therapist adaptations to: client culture/race/ethnicity (99 studies, g = .50); client preferences for type of therapy (51 studies, g = .28), client religion/spirituality (97 studies, g = .13 to .43), client stage of change (76 studies, g = .41), client reactance/resistance level (13 studies, g = .78), client coping style (32 studies, g = .53), and client attachment style (32 studies, g = .35). Over the next months, I will be reviewing in more detail these meta analyses of client factors and the practice implications of each so that therapists can use this evidence-base to help them to adapt to particular client characteristics.
Practice Implications
Practitioners will find that fitting the therapy to clients’ culture, stage of change, religion/spirituality, reactance/resistance, coping style, and attachment style will improve treatment outcomes. Doing so will have a greater impact on outcomes than the particular type of therapy provided or adapting treatment to the particular client diagnosis. The results of this large body of evidence suggests that therapists should no longer ask: “what is my theoretical orientation” but rather they should ask: “what relationship, adaptation, and approach will be most effective with this particular client”.
Adult Attachment as a Predictor of Psychotherapy Outcomes: A Meta Analysis
Levy, K.N., Kivity, Y., Johnson, B.N., & Gooch, C.V. (2018). Adult attachment as a predictor and moderator of psychotherapy outcome: A meta‐analysis. Journal of Clinical Psychology. Online first publication, DOI: 10.1002/jclp.22685.
Adult attachment refers to characteristic ways people manage their emotions and relationship styles. Securely attached individuals adaptively and flexibly experience emotions and they are able to give and receive love and support to others. Insecure attachment can be sub-categorized as avoidant or anxious attachment. Those who are anxiously attached tend to up-regulate their feelings so that they may feel easily overwhelmed, and they tend to be preoccupied with relationship loss. Those with avoidant attachment styles tend to down-regulate their emotions so that they have difficulty experiencing or expressing feelings, and they might dismiss the importance of relationships as a means of protecting themselves. John Bowlby, the founder of attachment theory, argued that psychotherapy had the potential to serve as a secure base from which individuals might explore themselves and relationships. He also described the therapist as a temporary attachment figure with which the patient might develop an emotional bond to promote change and for a corrective experience. In this meta-analysis, Levy and colleagues looked at whether attachment dimensions can change in psychotherapy and whether they can predict improvement in patient symptoms pre- to post-therapy. (A note on meta analysis. It is a method of systematically reviewing a research literature, combining the effect sizes in that literature, and summarizing these effects. Because meta analyses usually contain many studies, their results are much more reliable than the results of any single study, and so they provide the most solid basis for making practice recommendations). In this meta analysis, Levy and colleagues included 36 studies, totaling 3,158 clients. Higher client attachment security (or lower attachment insecurity) at the start of therapy was associated with better outcomes by post-treatment (r = 0.17, p < 0.001, 95% CI = [0.13, 0.22], k = 32). Also, greater improvement in attachment security (change in attachment security from pre- to post-treatment) predicted better outcomes (r = 0.16, p < 0.001, 95% CI = [0.07, 0.25], k = 15). When looked at separately, higher levels of either attachment anxiety or attachment avoidance were associated with poorer outcomes, and change in either type of attachment insecurity was associated with better outcomes. These effects appeared to be consistent regardless of the type of therapy (non-interpersonal vs interpersonal therapies).
Practice Implications
Although attachment insecurity is associated with poorer outcomes, change in attachment insecurity is possible with psychotherapy and this change is associated with better symptom outcomes. Therapists should expect longer and more challenging treatment with patients who are anxiously attached. Anxiously attached individuals may appear engaged early in therapy, but they are quick to anger, feel rejected, and become overwhelmed. Such individuals may benefit from help to contain their emotional experiences by repeating the treatment frame and increasing structure. They may also benefit from interpersonally-oriented therapy focused on reducing their preoccupation with relationship loss. Avoidantly attached individuals may appear aloof, but they may be easily overwhelmed by demands for closeness. Therapists may have to carefully balance the amount of interpersonal space or demands in treatment with these clients so that they remain in therapy.

Association Between Insight and Outcome of Psychotherapy
Jennissen, S., Huber, J., Ehrenthal, J.C., Schauenburg, H., & Dinger, U. (2018). Association between insight and outcome of psychotherapy: Systematic review and meta-analysis. The American Journal of Psychiatry. Published Online: https://doi.org/10.1176/appi.ajp.2018.17080847
For many authors, one of the purported mechanisms of change in psychotherapy is insight. In fact, the utility of insight for clients with mental health problems was first proposed over 120 years ago by Freud and Breuer. Briefly, insight refers to higher levels of self-understanding that might result in fewer negative automatic reactions to stress and other challenges, more positive emotions, and greater flexibility in cognitive and interpersonal functioning. Although insight is a key factor in some psychodynamic models, it also plays a role in other forms of psychotherapy. Experiential psychotherapy emphasises gaining a new perspective through experiencing, and for CBT insight relates to becoming more aware of automatic thoughts. Jennissen and colleagues defined insight as patients understanding: the relationship between past and present experiences, their typical relationship patterns, and the associations between interpersonal challenges, emotional experiences, and psychological symptoms. In this study, Jennissen and colleagues conducted a systematic review and meta analysis of the insight-outcome relationship, that is the relationship between client self-understanding and symptom reduction. They reviewed studies of adults seeking psychological treatment including individual or group therapy. The predictor variable was an empirical measure of insight assessed during treatment but prior to when final outcomes were evaluated. The outcome was some reliable and empirical measure related to symptom improvement, pre- to post- treatment. The review turned up 22 studies that included over 1100 patients mostly with anxiety or depressive disorders who attended a median of 20 sessions of therapy. The overall effect size of the association between insight and outcome was r = 0.31 (95% CI=0.22–0.40, p < 0.05), which represents a medium effect. Moderator analyses found no effect of type of therapy or diagnosis on this mean effect size, though the power of these analyses was low.
Practice Implications
The magnitude of the association between insight and outcome is similar to the effects of other therapeutic factors such as the therapeutic alliance. When gaining insight, patients may achieve a greater self-understanding, which allows them to reduce distorted perceptions of themselves, and better integrate unpleasant experiences into their conscious life. Symptoms may be improved by self-understanding because of the greater sense of control and master that it provides, and by the new solutions and adaptive ways of living that become available to clients.

Cultural Adaptation of Psychotherapy
Hall, G.C.N., Ibarak, A.Y., Huang, E.R., Marti, C.N., & Stice, E. (2016). A meta-analysis of cultural adaptations of psychological interventions. Behavior Therapy.
Cultural adaptation of psychological interventions involves identifying cultural contexts of behaviors and developing constructs of mental health functioning relevant to the cultural context. Most cultural adaptation of psychotherapies involves taking existing treatments originally developed for those of European ancestry and adapting them for another specific cultural group or context. However, a few efforts exist in which new treatments were developed within a particular culture to address culture-specific concerns. Eight dimensions along which interventions could be culturally adapted include: language, people, metaphors, content, concepts, goals, methods, and context. Some researchers have expressed concern that cultural adaptation could distance an intervention from its evidence-base, and reduce its effectiveness. In this meta analysis by Hall and colleagues, the researchers look closely at the effects all culturally adapted treatments and prevention methods. They reviewed 78 studies that included nearly 14,000 participants. All studies included culturally adapted interventions for individuals of non-European ancestry. For example, these included studies that adapted CBT interventions for various disorders (mainly depression and anxiety disorders), or studies that match therapist to client in terms of ethnicity. Only 5% of studies created a new intervention developed within a particular culture, whereas the vast majority of studies adapted an existing treatment initially developed for clients of European ancestry. The average effect size was g = .67 (confidence intervals not reported), indicating that culturally adapted interventions produced better outcomes than comparison conditions. Culturally adapted interventions were also more likely to result in better outcomes than the same interventions that were not adapted (g = .52). Effect sizes for cultural adaptation in treatment studies (g = .72) were larger than for prevention studies (g = .25), likely because participants in treatment studies had higher levels of initial psychopathology. There was little evidence that matching therapist and client on ethnicity was helpful.
Practice Implications
This meta analysis provides compelling evidence that cultural adaptation of existing treatments can result in more positive outcomes compared to not adapting the same treatment. The effect sizes may even underestimate the true effects of cultural adaptation because the outcome variables like measures of depression were rarely adapted to a specific culture (e.g., depression among Chinese participants may be expressed differently than depression among European participants, and most depression measures were created by and for Europeans).

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.
Psychotherapy That is Culturally Congruent for Chinese Clients
Xu, H. & Tracey, T.J.G. (2016). Cultural congruence with psychotherapy efficacy: A network meta-analytic examination in China. Journal of Counseling Psychology, 63, 359-365.
Cultural congruence refers to providing psychotherapy that is consistent with the client’s cultural context in its description of the etiology of symptoms and in its therapeutic procedures. In general, congruence of treatments with clients’ expectation, preferences, and beliefs is related to greater psychotherapy efficacy. And specifically identifying culturally appropriate or adapted treatments is important because this is often related to better therapy outcomes for ethnic and racial minorities. Psychotherapy as a professional practice developed recently in China. Cognitive-behavioral, existential-humanistic, and psychodynamic therapies have taken their place along side indigenous therapies including Naikan therapy, Taoism cognitive therapy, and Morita therapy. Historically in China mental health problems were seen as a disturbance in ying-yang or a sin committed in a previous life. Healing practices included engaging in altruism or religious practices to achieve redemption. Xu and Tracey argue that Chinese culture strongly endorses an experiential and subjective orientation and is less aligned with analytic and objective orientations. Using this understanding, the authors expected that experiential-humanistic and indigenous therapies would be more congruent and therefore more effective than cognitive-behavioral education or psychodynamic therapy in alleviating mental health issues. In this meta analysis, Xu and Tracey reported on 235 studies conducted in China that compared the various treatments to a control condition or to each other. There were too few studies of psychodynamic therapy, so it was not included in the analyses. All treatments were effective compared to a control condition with large effect sizes (g = .85 to 1.18). However, whereas experiential-humanistic and indigenous therapies were equally effective, each was significantly more effective (g = .34) than cognitive-behavioral psychoeducation.
Practice Implications
The three modalities, experiential-humanistic, indigenous, and cognitive-behavioral psychoeducation were effective. However the two therapies that were more experiential and subjective in nature were more effective to reduce Chinese clients’ symptoms. When working with Chinese clients, therapists may achieve better outcomes if they work on more experiential components (e.g., feelings and therapeutic relationship) and focus on subjective experiences (e.g., introspection and reflection). The results of the meta analysis suggest that when working with Chinese clients interpersonal processes and emotions should be the clinical focus and take priority over dysfunctional cognitions and psychoeducation.
