Comparative Efficacy of Cognitive Behavioral and Mindfulness Therapies in Reducing Post-Traumatic Stress Disorder Among Interpersonal Violence Survivors (COMPASS)

August 28, 2026 updated by: Khadija Raheel, GIFT University

"Comparative Efficacy of Cognitive Behavioral and Mindfulness Therapies in Reducing Post-Traumatic Stress Disorder Among Interpersonal Violence Survivors"

This study aims to compare the effectiveness of Cognitive Behavioral Therapy (CBT), Mindfulness-Based Therapy (MBT), and psychoeducation in reducing symptoms of post-traumatic stress disorder (PTSD) among adult survivors of interpersonal/domestic violence. Participants who meet the eligibility criteria will be randomly assigned to receive CBT, MBT, or psychoeducation. PTSD symptoms and related psychological outcomes, including emotion regulation, mindfulness, and perceived stress, will be assessed before treatment, after treatment, and at follow-up. The study seeks to determine whether CBT or MBT provides greater improvements in PTSD symptoms compared with psychoeducation and to identify the relative effectiveness of these evidence-based psychological interventions for survivors of interpersonal violence.

Study Overview

Detailed Description

Interpersonal/domestic violence is a major public health concern that is associated with a high prevalence of post-traumatic stress disorder (PTSD) and other adverse mental health outcomes. Although Cognitive Behavioral Therapy (CBT) and Mindfulness-Based Therapy (MBT) have each demonstrated effectiveness in reducing PTSD symptoms, few randomized controlled trials have directly compared their relative efficacy among survivors of interpersonal violence, particularly in low- and middle-income settings. This study addresses this evidence gap by evaluating and comparing CBT and MBT using a randomized controlled trial design.

This is a parallel-group randomized controlled trial with three study arms: (1) Cognitive Behavioral Therapy (CBT), (2) Mindfulness-Based Therapy (MBT), and (3) psychoeducation as an active control. Approximately 60 adult survivors of interpersonal/domestic violence who meet DSM-5 criteria for PTSD following screening and diagnostic assessment will be randomly assigned in equal numbers to one of the three intervention groups. Participants will complete baseline, post-intervention, and follow-up assessments.

The primary objective is to compare the effectiveness of CBT, MBT, and psychoeducation in reducing PTSD symptom severity. Secondary objectives include evaluating changes in emotion regulation, mindfulness, perceived stress, and other related psychological outcomes following the interventions. The study hypothesizes that both CBT and MBT will produce greater reductions in PTSD symptoms than psychoeducation, while also examining whether one active intervention demonstrates superior effectiveness for specific PTSD symptom domains and psychological outcomes.

The findings will contribute to the evidence base for trauma-informed psychological interventions and may inform clinical practice by identifying effective, culturally relevant treatment approaches for survivors of interpersonal/domestic violence.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Cognitive Behavioral Therapy (CBT)
Cognitive Behavioral Therapy (CBT), a structured psychological intervention for post-traumatic stress disorder (PTSD) following interpersonal/domestic violence. The intervention aims to reduce PTSD symptoms through psychoeducation, cognitive restructuring, behavioral techniques, coping skills training, and relapse prevention. Participants will complete assessments at baseline, post-intervention, and follow-up.
Cognitive Behavioral Therapy (CBT) is a structured, trauma-informed psychological intervention designed to reduce post-traumatic stress disorder (PTSD) symptoms among adult survivors of interpersonal/domestic violence. The intervention includes psychoeducation, cognitive restructuring, behavioral activation, coping skills training, trauma-focused cognitive and behavioral techniques, and relapse prevention.
Other Names:
  • CBT
Experimental: Mindfulness-Based Therapy (MBT)
Participants assigned to this arm will receive Mindfulness-Based Therapy (MBT), a structured psychological intervention designed to reduce PTSD symptoms through mindfulness meditation, breathing exercises, body awareness, acceptance, and emotion regulation practices. Participants will complete assessments at baseline, post-intervention, and follow-up.
Mindfulness-Based Therapy (MBT) is a structured psychological intervention that incorporates mindfulness meditation, breathing exercises, body awareness, acceptance, present-moment awareness, and emotion regulation strategies to reduce PTSD symptoms and improve psychological well-being among adult survivors of interpersonal/domestic violence.
Other Names:
  • MBT
Active Comparator: Psychoeducation
Participants assigned to this arm will receive a structured psychoeducation program providing information about trauma, post-traumatic stress disorder (PTSD), common trauma responses, coping strategies, stress management, safety planning, and available support services. This intervention serves as the active comparison group. Participants will complete assessments at baseline, post-intervention, and follow-up.
Psychoeducation is a structured behavioral intervention that provides information about trauma, PTSD symptoms, common psychological responses to interpersonal/domestic violence, coping strategies, stress management, safety planning, and available support resources. It serves as the active comparator and does not include the therapeutic components of CBT or MBT

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Post-Traumatic Stress Disorder (PTSD) Symptom Severity
Time Frame: Baseline, immediately post-intervention, and 3-month follow-up
Change in PTSD symptom severity will be assessed using the PTSD Checklist for DSM-5 (PCL-5). The PCL-5 is a validated 20-item self-report questionnaire measuring PTSD symptoms, with higher scores indicating greater symptom severity. The primary analysis will compare changes in PCL-5 scores among the Cognitive Behavioral Therapy (CBT), Mindfulness-Based Therapy (MBT), and Psychoeducation groups.
Baseline, immediately post-intervention, and 3-month follow-up

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Emotion Regulation
Time Frame: Baseline, immediately post-intervention, and 3-month follow-up
Emotion regulation will be assessed using the Emotion Regulation Questionnaire (ERQ). Changes in participants' emotion regulation abilities will be compared across the three intervention groups.
Baseline, immediately post-intervention, and 3-month follow-up
Change in Mindfulness
Time Frame: Baseline, immediately post-intervention, and 3-month follow-up
Mindfulness will be assessed using the Mindful Attention Awareness Scale (MAAS). Changes in mindfulness levels will be compared among the intervention groups.
Baseline, immediately post-intervention, and 3-month follow-up
Change in Perceived Stress
Time Frame: Baseline, immediately post-intervention, and 3-month follow-up
Perceived stress will be assessed using the Perceived Stress Scale (PSS). Changes in perceived stress will be compared across the three intervention groups.
