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.

How Effective is Computerized CBT in Treating Depression in Primary Care?
Gilbody, S., Littlewood, E., Hewitt, C., Brierley, Tharmanathan, P....White, D. (2015). Computerised cognitive behaviour therapy (cCBT) as treatment for depression in primary care (REEACT trial): Large scale pragmatic randomised controlled trial. BMJ, 351, h5627. Doi: 10.1136/bmj.h5627.
Depression is one of the most common reasons why people see family physicians for consultation. The personal and economic burden of depression is high, such that depression is the leading cause of disability worldwide. Effective treatments for depression include antidepressant medications and psychotherapy. Cognitive behavioral therapy (CBT) is an effective treatment for depression, but is not always accessible for those who live in remote areas, and for those who cannot easily find or afford a trained psychotherapist. One solution, touted by some is to provide computerized CBT (cCBT) via internet or CD. In fact, the National Institute for Health and Care Excellence (NICE) in the UK recommend cCBT programs as a first step of care for depression. Commercially available cCBT programs include “Beating the Blues”, and freely available programs include “MoodGYM”. Previous research shows a large effect of cCBT for reducing depressive symptoms, but non-adherence (i.e., not completing the modules) and patient dropout rates tend to be high. Another issue is that most of the studies of cCBT were conducted by the developers of the programs, and so there may be researcher allegiance effects that could bias the findings. In this large trial, Gilbody and colleagues asked: “How effective is supported computerized cognitive behavior therapy (cCBT) when it is offered in addition to usual primary care in adults with depression?” The authors recruited 691 depressed patients seen in primary care with a general practitioner (GP) in the UK. All participants had access to a computer and high speed internet. The participants were randomly assigned to receive: (1) usual GP care plus 8 50-minute sessions of Beating the Blues, or (2) usual GP care plus 6 weekly modules of MoodGYM, or (3) only usual GP care. Usual GP care included providing antidepressants, counselling, or brief psychotherapy which are all offered as part of the UK National Health Service. Computerized CBT was supported by weekly telephone calls followed by reminder emails to encourage participants to access, use, and complete the programs. At 4 months after the start of treatment, about half of all participants were no longer depressed, and there were no differences between the three study conditions on any of the outcomes (e.g., depression, quality of life). The results were consistent up to 2 years post treatment. However, only about 17% of those receiving one of the cCBT treatments completed all of the sessions. The average number of sessions completed of cCBT was very low (Beating the Blues = 2 out of 8 sessions; MoodGYM = 1 out of 6 sessions). The authors concluded that there was no significant benefit of adding supported cCBT to usual GP care.
Practice Implications
Adding cCBT to usual GP care did not provide added benefit to depressed patients. Low adherence and low engagement with cCBT likely reduced the utility of computerized delivery of therapy. It is possible that more intensively supported cCBT (i.e., with weekly face to face contacts) might have improved the added value of cCBT, but would also have reduced the practically utility and accessibility of cCBT. Those who are depressed might have difficulty with summoning the energy and concentration necessary to repeatedly log on to computers and engage in computerized or internet based treatment.

Are Therapist Adherence and Competence to a Treatment Manual Related to Patient Outcomes?
The Great Psychotherapy Debate: Since in April, 2015 I review parts of The Great Psychotherapy Debate (Wampold & Imel, 2015) in the PPRNet Blog. This is the second edition of a landmark, and sometimes controversial, book that surveys the evidence for what makes psychotherapy work. You can view parts of the book in Google Books.
The conduct of psychotherapy trials almost always requires that therapists be adherent and competent in delivering a manualized therapy intervention. Treatment adherence usually refers to the extent to which a therapist used the intervention prescribed by a treatment manual. Therapist competence refers specifically to a therapist’s skill in delivering the therapy. So “competence” in the context of psychotherapy research typically refers only to performing a certain type of treatment. Wampold and Imel argue that these definitions are consistent with a Medical Model of psychotherapy that emphasizes delivering specific active ingredients of a treatment. The Contextual Model of psychotherapy, on the other hand might define a therapist as competent to the extent that the therapist is interpersonally skilled, empathic, and able to engage clients in the actions of the therapy. Wampold and Imel report on a meta analysis of 28 studies conducted by Webb and colleagues (2010) who found a small and non-significant relationship between therapist adherence and patient outcomes (r = .02), and a small and non-significant relationship between therapist competence and patient outcomes (r = .07). Type of treatment (e.g., CBT, IPT, dynamic) did not affect these associations – in other words adherence and competence were not more important to CBT than to other treatments. However, competence seemed to be more important for the treatment of depression (r = .28). Perhaps depression responds better to specific techniques. The finding that competence was generally not related to outcomes was surprising, however generally competence is narrowly defined as how well a therapist delivered the treatment not how well the therapist was able to establish a therapeutic context. Previous researchers concluded that when clients liked working with a therapist, clients got better, and therapists were rated as more competent as a result. A number of studies appear to indicate that therapist competence is really a function of the client’s characteristics not to what the therapist does. For example, clients with more severe personality problems could make a therapist appear less competent, and these clients may have poorer outcomes. If this is the case, it would create a paradoxical situation in which therapists’ appearance of competence (i.e., ability to deliver a manualized intervention well) is largely determined by the client and not by the therapist.
Practice Implications
In contrast to the findings about adherence and competence, the therapeutic alliance is robustly related to patient outcomes. Also in contrast, the size of the alliance-outcome relationship is almost entirely due to the skills of the therapist, not the client’s characteristics. In other words, therapist competence is not a matter of whether they can do a good job of following a manual, but rather therapist competence is likely a matter of creating the right conditions (i.e., interpersonal skill, alliance, empathy, etc.) for delivering evidence-based interventions by which many clients improve. However, some therapists are better at these facilitative interpersonal skills than others.
