This is a plain English summary of an original research article
The quality of interactions between therapists and their patients is as good by telephone as in face-to-face sessions. A review of the evidence found little difference in the interaction regardless of how therapy was delivered. Telephone sessions were shorter but measures such as empathy and attentiveness, as well as patients’ readiness to disclose information, was similar in both settings.
Traditionally, psychological therapy is delivered face-to-face but increasingly it is delivered in new formats including by telephone, video and online. There is already evidence, from clinical trials and observational evaluations, that telephone therapy is as successful as face-to-face treatment in treating mild to moderate mental health problems. Despite this, both therapists and patients remain concerned about the use of telephone therapy.
With recent policy moves to increase the amount of therapy offered by telephone, as well as the current restrictions placed on therapists and patients due to the COVID-19 pandemic, the findings of this review could provide reassurance that this form of therapy does not hinder the relationship between therapist and patient.
What’s the issue?
Educational materials tend to focus on face to face interactions. Therapists often claim that a lack of visual cues in telephone-based therapy sessions may be detrimental to their interaction with patients. There is little evidence to support this belief.
Telephone-delivered psychological interventions are recommended by the National Institute of Health and Care Excellence (NICE) for the treatment of anxiety and depression. Reviews of previous scientific studies show that telephone and face-to-face therapy have comparable benefits for depression in primary care.
The NHS now offers a service called Improving Access to Psychological Therapy (IAPT) for people with depression and anxiety. Many sessions are carried out by telephone in line with NICE guidelines. This service is valuable, but many therapists say they do not feel they have adequate training in working over the phone.
This study was part of a larger project, Enhancing the Quality of Psychological Interventions Delivered by Telephone (EQUITy), which is designed to support the improvement of psychotherapy delivered by telephone. In light of the COVID-19 pandemic, the design of the study is being enhanced to ensure findings are made available quickly.
The researchers searched databases for papers comparing telephone-delivered and face-to-face therapy for mental health problems. They carried out a systematic review of 15 papers which focused on the interaction between therapist and patient.
Telephone sessions were shorter than face-to-face therapy, but there was no evidence of differences in the way therapists and patients rated their interactions, the amount of information a patient disclosed, empathy, attentiveness or participation.
One study found introverted individuals were more likely to discuss their emotions by telephone than when face-to-face. The researchers said this demonstrated one area where there could be potential benefits to therapy delivered via telephone, at least for some groups.
Why is this important?
Telephone-based psychological therapy for anxiety and depression already forms part of clinical guidelines in the UK. Even prior to the current COVID-19 pandemic, a growing proportion of psychological therapy was being delivered by telephone and other remote methods. This study supports the case for telephone treatment being both acceptable and effective. The implications are less about changing guidelines and more about making patients and practitioners feel confident that they can achieve all the core ingredients of a good psychological therapy session on the telephone.
Many patients and therapists have been forced to switch to telephone-based therapy due to the restrictions imposed during the pandemic. But telephone psychological therapy will continue to have an important role even when lockdown ends. There are many other reasons why people can find the telephone better suited to their needs, such as issues with mobility, caring responsibilities, or living in rural areas.
The research itself demonstrated a lack of studies that directly compare telephone and face-to-face therapy. More studies comparing different types of therapy such as cognitive behavioural therapy (CBT) and psychoanalysis are needed. It will also be important to look at different patient groups.
Video therapy was not included in this review but could be an important area for further study as more people are using video tools for therapy during the COVID-19 pandemic.
