Practice-Based Psychotherapy Research
To Improve The Wellbeing Of Our Community

PPRNet Blog: November 2018


Giorgio A. TascaAt the PPRNet conference in November 2012 over 100 psychotherapy clinicians, researchers, and educators were very keen to receive ongoing information about psychotherapy research that is practice-oriented and presented in an easily readable format. And so the PPRNet Blog was born.

About once a month I will review and summarize two or three published psychotherapy research articles. As part of the summary, I will highlight the practice implications of the research.

Because of copyright issues, we cannot post the full text of the articles, but we will provide a link to the abstract on the publisher's web site. I will also post the author's email address. Most authors are very happy to share their work. So if you want a copy of the article send the author an email with a request for a pdf or reprint.

At the bottom of each review you can post a comment, and comment on your colleagues' comments. I will update these as frequently as possible.

If you have ideas for an article to review or a topic you would like to see covered, please send me an email at pprnet@toh.on.ca.

blogAdapting 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 and E-Newsletter 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”.

blogPsychotherapy Relationships That Work: Becoming an Evidence-Based Therapist II

Norcross, J. C., & Lambert, M. J. (2018). Psychotherapy relationships that work III. Psychotherapy, 55(4), 303-315.

Relationship factors in psychotherapy are some of the most important predictors of patient outcomes. They outweigh factors like the type of therapy provided in determining whether patients get better after psychotherapy.  In this second overview article, Norcross and Lambert provide a review of 17 meta-analyses of relationship factors in psychotherapy that contribute to positive outcomes. Like the review of patient factors also found in this blog and E-Newsletter, this article briefly outlines those evidence-based relationship factors that reliably predict patient outcomes in psychotherapy. The therapeutic relationship refers to how the therapist and patient relate to each other, or their interpersonal behaviors. By contrast, techniques or interventions refer to what is done by the therapist. Practice guidelines typically focus on interventions or therapeutic orientation. As the authors argue, what is missing from treatment guidelines are the person of the therapist and the therapeutic relationship – evidence for which is backed up by 5 decades of research. Even in studies of highly structured manualized psychotherapy for a specific disorder in which efforts were made to reduce the effect of individual therapist, up to 18% of outcomes (a moderate to large effect) could be attributed to the person of the therapist. By contrast somewhere between 0% and 10% of outcomes (a small to moderate effect) is attributable to specific treatment methods. So, which therapeutic relationship factors are reliably related to patient outcomes? These include: the therapeutic alliance in individual therapy (306 studies, g = .57) couple therapy (40 studies, g = .62), and adolescent psychotherapy (43 studies, g = .40), collaboration (53 studies, g = .61) and goal consensus (54 studies, g = .49), cohesion in group therapy (55 studies, g = .56), therapist empathy (82 studies, g = .58), collecting and delivering client feedback or progress monitoring (24 studies, g = .14 to .49), managing countertransference (9 studies, g = .84), and repairing therapeutic alliance ruptures (11 studies, g = .62) among others. Over the next few months, I will be reviewing these meta analyses in more detail to discuss how therapists can use this evidence base to improve their patients’ outcomes.

Practice Implications
The research as a whole indicates that therapists should make the creation and cultivation of the therapeutic relationship a primary goal of therapy. Factors such as managing the therapeutic alliance, repairing alliance ruptures, engaging in ongoing progress monitoring, managing countertransference and others should be used to modify treatments and interpersonal stances in order to maximize outcomes. When seeking out professional development and training, practitioners should focus on evidence-based relationship factors (managing the alliance, judicious self disclosure, managing emotional expression, promoting credibility of the treatment, collecting formal feedback, managing countertransference) in addition to focusing on evidence-based treatments.

blogAdult 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 (d = 0.35, 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 (d = 0.32, 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.
