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.

Does Treatment Fidelity Lead to Better Patient Outcomes?
Alexandersson, K., Wågberg, M., Ekeblad, A., Holmqvist, R., & Falkenström, F. (2022) Session-to-session effects of therapist adherence and facilitative conditions on symptom change in CBT and IPT for depression. Psychotherapy Research, DOI: 10.1080/10503307.2022.2025626.
There has been a long-standing debate in psychotherapy about whether a therapist’s capacity to be adherent to treatment manual and to be competent in delivering specific treatment interventions leads to better patient outcomes. Some argue that rigid adherence may lead to worse outcomes, and meta-analytic research suggests that specific treatment adherence or competence has no impact on outcomes. Others argue that facilitative therapist behaviors (empathy, warmth, involvement, support) and the therapeutic alliance plays a more important role in whether patients get better. It is possible that psychotherapy research designs and rudimentary data analytic methods obscure the effects of therapist treatment adherence. In this study, Alexandersson and colleagues collected data from a randomized controlled trial of cognitive behavioral therapy (CBT) and interpersonal psychotherapy (IPT) for depression. The researchers rated therapist behaviors (adherence to the treatment manual, facilitative behaviors) from recorded therapy sessions. They also assessed patient ratings of the therapeutic alliance after every session. Alexandersson and colleagues used a statistical modeling procedure that allowed them to look specifically at the effects of therapist adherence in a previous session on a patient’s depressive symptoms in a subsequent session. Their results did not show any effects of therapists’ use of specific CBT or IPT techniques on patient outcomes. Facilitative therapist behaviors in a previous session predicted better patient outcomes in the next session for CBT but not for IPT. The effects of facilitative therapist behaviors on outcomes were partially explained by levels of the therapeutic alliance. That is, facilitative behaviors among CBT therapists led to higher therapeutic alliance ratings by patients, which in turn led to lower patient depression scores in the subsequent session.
The authors were a little surprised that facilitative therapist behaviors (empathy, warmth, involvement, support) led to better outcomes in CBT but not in IPT. They speculated that therapist relational competence might be especially relevant early in CBT to facilitate a strong alliance, which in turn reduces depressive symptoms among patients. The demanding tasks of CBT (behavioral activation, homework) might mean that therapists’ warmth, support and engagement are important precursors to patients benefitting from the therapy.
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.
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.
