Evidence-Based Brief Psychological Treatment for Emotional Disorders in Primary and Specialized Care: Study Protocol of a Randomized Controlled Trial

Cost-effectiveness and cost-utility evaluation of individual vs. group transdiagnostic psychological treatment for emotional disorders in primary care (PsicAP-Costs): a multicentre randomized controlled trial protocol

BACKGROUND

Emotional disorders are common, and they have become more prevalent since the COVID-19 pandemic. Due to a high attendance burden at the specialized level, most emotional disorders in Spain are treated in primary care, where they are usually misdiagnosed and treated using psychotropic drugs. This contributes to perpetuate their illness and increase health care costs. Following the IAPT programme and the transdiagnostic approach, the PsicAP project developed a brief group transdiagnostic cognitive-behavioural therapy (tCBT) as a cost-effective alternative. However, it is not suitable for everyone; in some cases, one-on-one sessions may be more effective. The objective of the present study is to compare, in cost-benefit terms, group and individual tCBT with the treatment usually administered in Spanish primary care (TAU).

METHODS

A randomized, controlled, multicentre, and single-blinded trial will be performed. Adults with mild to moderate emotional disorders will be recruited and placed in one of three arms: group tCBT, individual tCBT, or TAU. Medical data and outcomes regarding emotional symptoms, disability, quality of life, and emotion regulation biases will be collected at baseline, immediately after treatment, and 6 and 12 months later. The data will be used to calculate incremental cost-effectiveness and cost-utility ratios.

DISCUSSION

This trial aims to contribute to clinical practice research. The involvement of psychologists in primary care and the implementation of a stepped-care model for mental disorders are recommended. Group therapy and a transdiagnostic approach may help optimize health system resources and unblock waiting lists so that people can spend less time experiencing mental health problems.

Effectiveness of brief group transdiagnostic therapy for emotional disorders in primary care: A randomized controlled trial identifying predictors of outcome

AbstractBrief transdiagnostic psychotherapy is a possible approach for emotional disorders in primary care. The objective of the present randomized controlled trial was to determine its effectiveness compared with the treatment as usual based on pharmacological interventions in patients with mild/moderate symptoms. In addition, emotional regulation strategies and cognitive factors were studied as potential predictors. Participants (N = 105) were assigned to brief group therapy based on the Unified Protocol (n = 53) or treatment as usual (n = 52). They were assessed before and after the interventions. Mean differences and stepwise regression analyses were performed. Brief group transdiagnostic psychotherapy was more effective than medication in reducing all clinical symptoms (p = .007 for generalized anxiety; p = .000 for somatization; p = .000 for panic disorder; and p = .041 for depression) and in modifying emotional regulation strategies and cognitive processes (p = .000 for cognitive reappraisal, expressive suppression, worry, rumination, and metacognition) with moderate/high effect sizes. Besides, it was found that these variables acted as predictors of the therapeutic change. It is concluded that brief therapies could be an accurate treatment for mild/moderate emotional disorders in primary care due to their cost-effective characteristics.

Brief psychological treatments for emotional disorders in Primary and Specialized Care: A randomized controlled trial

Background/Objective Brief transdiagnostic psychotherapies are a possible treatment for emotional disorders. We aimed to determine their efficacy on mild/moderate emotional disorders compared with treatment as usual (TAU) based on pharmacological interventions. Method: This study was a single-blinded randomized controlled trial with parallel design of three groups. Patients (N = 102) were assigned to brief individual psychotherapy (n = 34), brief group psychotherapy (n = 34) or TAU (n = 34). Participants were assessed before and after the interventions with the following measures: PHQ-15, PHQ-9, PHQ-PD, GAD-7, STAI, BDI-II, BSI-18, and SCID. We conducted per protocol and intention-to-treat analyses. Results: Brief psychotherapies were more effective than TAU for the reduction of emotional disorders symptoms and diagnoses with moderate/high effect sizes. TAU was only effective in reducing depressive symptoms. Conclusions: Brief transdiagnostic psychotherapies might be the treatment of choice for mild/moderate emotional disorders and they seem suitable to be implemented within health care systems.
