A comparison of emotion-focused therapy and cognitive-behavioral therapy in the treatment of generalized anxiety disorder: Results of a feasibility randomized controlled trial.

Generalized anxiety disorder (GAD) is a chronic mental health difficulty typically present in primary care settings. Cognitive-behavioral therapy (CBT) is the psychological intervention with the best evidence for its efficacy for GAD. The development of other psychological interventions can increase client choice. This feasibility trial examined an initial assessment of the efficacy of EFT in comparison to CBT in the treatment of GAD in the context of an Irish public health service. The trial provided information on recruitment, therapist training/adherence, and client retention relevant for a potential noninferiority trial. A randomized controlled trial compared the efficacy of EFT versus CBT for GAD. Both therapies were offered in a 16-20 sessions format. Therapists (n = 8) were trained in both conditions and offered both therapies. Clients were randomly assigned to the two therapies EFT (n = 29) and CBT (n = 29). Outcomes were assessed using several measures, with the Generalized Anxiety Disorder-7 (GAD-7) being the primary outcome. Clients were assessed at baseline, week 16, end of therapy, and at 6-month follow-up. Therapists were able to learn the two models after a short training and showed moderate levels of adherence. Although not statistically significant, the drop out from treatment was 10% for EFT and 27% for CBT. The two therapies showed large pre-post change and similar outcomes across all measures, with these benefits retained at 6-month follow-up. Results suggest that EFT is a potentially promising treatment for GAD. Further investigation is indicated to establish its potential to expand the available psychological therapies for GAD.

A comparison of emotion-focused therapy and cognitive-behavioural therapy in the treatment of generalised anxiety disorder: study protocol for a randomised controlled trial.

BACKGROUND: Generalised anxiety disorder (GAD) is a chronic and debilitating condition characterised by high co-morbidity. Alongside pharmacological treatment, cognitive behavioural therapy (CBT) is an established psychological therapy for GAD. Its effectiveness is limited, however, with only an estimated 50% of clients presenting in the non-clinical range after a course of treatment. Furthermore, not all clients prefer CBT as a psychological therapy. Recently, emotion-focused therapy (EFT) was developed for GAD and was tested in an open trial with promising results. METHODS/DESIGN: The present research project is a feasibility testing randomised controlled trial (RCT) that compares the efficacy of EFT with an established treatment for GAD, CBT. Sixty clients presenting in a primary care psychology/counselling service will be randomly assigned to one of two conditions: EFT or CBT. Outcomes will be assessed using several measures (Generalised Anxiety Disorder-7, Generalised Anxiety Disorder Severity Scale, Patient Health Questionnaire-9, and Clinical Outcome in Routine Evaluation - Outcome Measure). Clients will be assessed prior to and at the end of therapy, as well as at 6-month follow-up. On the basis of findings from the initial open EFT trial with regard to the optimal length of therapy, it is proposed that therapy last between 16 and 20 sessions. DISCUSSION: This study aims to test the feasibility of a full comparison RCT. It will test subject recruitment, therapist adherence to manualised treatment, and client retention rates. It will also provide estimates of comparative outcomes that can inform power calculations for a definitive trial. TRIAL REGISTRATION: ISRCTN Registry, ISRCTN52689081 . Registered on 24 October 2017.
