Efficacy of TBCT, MBHP and PPT for PTSD During the Covid-19 Pandemics

April 1, 2025 updated by: Fundação Bahiana de Infectologia

A Randomized Clinical Trial to Assess the Efficacy of Online Treatment With Trial-based Cognitive Therapy, Mindfulness-based Health Promotion and Positive Psychotherapy for Post-traumatic Stress Disorder During the Covid-19 Pandemics

The psychotherapies to be assessed in the present study, delivered on-line, are: trial-based cognitive therapy (TBCT), mindfulness-based health promotion (MBHP), and positive psychotherapy (PPT). Objectives: 1) to assess the efficacy of TBCT compared to MBHP and PPT in reducing the symptoms of PTSD during the COVID-19 pandemic.

Study Overview

Detailed Description

Background: Research has suggested the use of different forms of psychotherapy to decrease drop-out rates in the post-traumatic stress disorder (PTSD) treatment. The psychotherapies to be assessed in the present study are: trial-based cognitive therapy (TBCT), mindfulness-based health promotion (MBHP) and Positive psychotherapy (PPT). Objectives: Our objectives are: 1) to assess the efficacy of TBCT compared to MBHP and PPT to reduce the symptoms of PTSD in the context of the COVID-19 pandemic, all delivered online; 2) to compare the efficacy of these psychotherapies in reducing symptoms of anxiety and depression, and in improving well-being; 3) to describe how patients and professionals perceive teletherapy. Methods: This is a three-arm, randomized, multicenter, single-blind, clinical trial. An estimated sample of 135 patients will receive either TBCT, MBHP or PPT, individual, weekly visits, totaling thirteen sessions. The primary outcome measure will be the CAPS-5, and the secondary outcome measures will be the Hospital Anxiety and Depression Scale (HADS), the Negative Core Beliefs Inventory (NCBI), and the Trauma-Related Guilt Inventory (TRGI). Other measures are the WHO-5 Well-being Index (WHO-5), and the California Psychotherapy Alliance Scale (CALPAS-P). Also, questions about patients perception of teletherapy will be asked. Expected results: PTSD symptoms are expected to be reduced after TBCT, MBHP and PPT. The null hypothesis is that no statistical difference is expected to be found among the three psychotherapies, as opposed to the alternative hypothesis that TBCT and MBHP are superior to PPT.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Trial-Based Cognitive Therapy
TBCT (de Oliveira, 2008) is a novel transdiagnostic approach (Wenzel, 2017). It has been shown to be effective for depression (Hemanny et al., 2019), social anxiety disorder (Neufeld et al., 2020; Caetano et al., 2018; de Oliveira et al., 2011; Powell et al., 2013), and PTSD (Duran et al., 2020). TBCT differs from other CBT approaches in that it introduces a new, organized, and systematic approach to change dysfunctional negative core beliefs, and allows cognitive, emotional, and experiential work to be done simultaneously (de Oliveira, 2016). Interestingly, it incorporates a courtroom metaphor to challenge dysfunctional core beliefs conceptualized as self-accusations (de Oliveira, 2016). TBCT is an example of assimilative psychotherapy integration that relies on Beckian CBT (de Oliveira, 2016). It incorporates and integrates components of other psychotherapies (Delavechia et al., 2016).
TBCT is an approach that includes psychoeducation and cognitive restructuring techniques concerning automatic thoughts, underlying assumptions and core beliefs related to the traumatic events. It is conducted in a therapeutic setting that makes use of experiential techniques, allowing the patient to refer to him/herself in the third person and thus taking distance from him or herself. One of TBCT techniques for dealing with guilt and shame, emotions that provoke great limitation to patients with PTSD, is the participation grid (PG). Another important technique is the consensual role-play (CRP), designed to help patients resolve ambivalence and make decisions. In addition, the most important TBCT technique, the Trial, was developed to help patients change dysfunctional negative core beliefs. Therapists who will conduct this approach have a specialization level in CBT. In this study, this treatment will be delivered in 14 sessions, weekly, individualy, one session by week and on line.

Active Comparator: Mindfulness-Based Health Promotion
The Mindfulness-Based Stress Reduction (MBSR) program was created by Jon Kabat-Zinn and colleagues at the University of Massachusetts Medical Center in 1979, and it is an intervention whose effects on mental health and quality of life has produced several studies worldwide, both in clinical and non-clinical populations. Several protocols have been developed based on the MBSR aimed at specific publics, such as the Mindfulness-Based Health Promotion (MBHP) program developed by the Mente Aberta - Brazilian Center for Mindfulness and Health Promotion. The MBHP program was inspired by the original MBSR model but adapted to the context of the Brazilian Health Care (SUS) system, addressing chronic conditions and mental disorders as well (TROMBKA et al., 2018; LOPES et al., 2019; SALVO et al., 2018).
The MBHP protocol is a structured program developed over 8 sessions, in group, where participants (8-15 people) meet every week for 2 hours (standard duration of one session), to experience the concepts and techniques of mindfulness. Participants are also given suggestions of daily activities to be implemented at home or in the workplace, that last in average 15-20 minutes, but may last up to 45 minutes in the case of more motivated and compliant participants. They are also encouraged to incorporate the idea of Mindfulness in their daily lives (the so-called "informal practice"), so that all daily activities somehow become opportunities to practice Mindfulness. In this study, this treatment will be delivered in 14 sessions, weekly, individualy, one session by week and on line.

Active Comparator: Positive psychotherapy
Positive psychotherapy (PPT) seeks to understand positive emotions, psychological potentialities and healthy human / social / institutional functioning, and to apply this knowledge to help people and institutions, with a focus on prevention and promotion of mental health (SELIGMAN et al., 2005). Originally, PP focused on happiness and subjective well-being (SELIGMAN, 2010; SELIGMAN; CSIKSZENTMIHALYI, 2000). Then, the studies gained a broader view of psychological well-being and another similar proposal entitled PERMA, which is composed of the following five spheres: positive emotions - P; engagement - E; relationships - R; meaning - M; and achievement - A. (RYFF, 2013; SELIGMAN, 2012). Although positive psychology aims to be a way of looking at life, some psychotherapeutic proposals, such as positive psychotherapy (PPT), have been developed, and clinical studies have been replicated in different clinical and cultural contexts (RASHID; SELIGMAN, 2019; RICHES et al., 2016).
PPT is the clinical and therapeutic work derived from PP. PPT consists of 15 specific practices that have been empirically validated, either separately, or in conjunction with two or three practices. After empirical validation, these practices were organized in a cohesive protocol of 15 sessions called PPT. Many of these practices have been studied through online interventions. In the present study, the protocol will be reduced to 14 sessions, with sessions called positive relationships, positive communication, and practical wisdom removed. It was understood that the other 12 would be more easily adapted to the moment of the study. (DUCKWORTH; STEEN; SELIGMAN, 2005; MONGRAIN; ANSELMO-MATTHEWS, 2012; RASHID; SELIGMAN, 2019). In this study, this treatment will be delivered in 14 sessions, weekly, individualy, one session by week and on line.
