TraumaRelief App: A Pilot RCT Assessing Feasibility and Acceptability

The world experiences a high rate of traumatic events. Even if PTSD is not diagnosed, traumatic events can significantly affect people's lives. Traditional face-to-face therapies often face challenges, such as financial constraints, expensive therapy sessions, time restrictions, fear of stigma, and difficulties in accessing clinical psychologists. These challenges motivated us to develop new methods. Particularly in Turkey, there is neither sufficient infrastructure nor existing applications dedicated to addressing trauma-related complications. The development of the 'TraumaRelief' app is a pioneering initiative aimed at bridging this gap, targeting the resolution of these prevalent issues by introducing an accessible, innovative solution. The newly developed "TraumaRelief" app aims to provide solutions to these issues. This app contains eight modules: online video talks, psychoeducation, coping with symptoms, mindfulness-based relaxation exercises, imagery exposure, CBT (Cognitive Behavioral Therapy)-based daily exercises, therapist messaging, emergency contact access. The purpose of this study is to test the feasibility and acceptability of this newly developed application through a pilot randomized controlled trial.

"TraumaRelief" consists of eight modules. These are:

1. Psychoeducation Module: This module addresses fundamental questions-What is trauma? What is PTSD? What are the symptoms of PTSD?-and elaborates on related problems such as sleep, nutrition, and anger. It is designed to provide comprehensive information and guidance on these issues and comprises 10,000 words and eight animated videos (approximately 40 minutes in total).
2. Coping with Symptoms Module: This module offers 10,000 words and six animations (around 40 minutes in total) featuring information and exercises tailored to manage PTSD and related issues.
3. Imaginary Exposure Module: The module including 4,000 words and two audio recordings details the concept of imaginary exposure. The elements of this exposure are the creation of a list of avoided and uncomfortable situations, and of an hierarchy of fear, alongside instructions for imaginary exposure to avoided objects and the traumatic event itself.
4. Daily Exercises: Featuring 14 distinct audio recordings-ranging from relaxation, body scanning, breathing exercises, positive visualization, thought awareness, to compassion (each recording varies between 5 and 17 minutes)-this module integrates exercises such as automatic thought questioning and reviews, daily activity forms, and an enjoyable activity list, as directed in the coping with symptoms module.
5. Online Meeting Module: Facilitates video calls with psychologists via phone or e mail, enhancing therapeutic engagement.
6. Messaging with the Therapist: This module enables participants to send messages to their therapists through the application in emergency situations, ensuring timely support.
7. Myself Module: Each time users access the psychoeducation and coping with symptoms modules, they assess their stress level, contributing to a personalized stress graph.
8. Emergency Module: Provides contact information for relevant institutions in high-risk scenarios, such as suicidal ideation, facilitating immediate assistance.

Application Usage Pattern: Post-registration, access to subsequent modules is contingent upon the completion of prior ones, ensuring a structured progression through the content. For instance, the Imaginary Exposure Module is unlocked only after completing at least eighty percent of the Psychoeducation Module, ensuring participants have a foundational understanding before proceeding.

This pilot randomized controlled study aims to evaluate the feasibility, acceptability, and preliminary efficacy of the "TraumaRelief" application for individuals who have experienced traumatic events. The research primarily focuses on measuring application compliance and user satisfaction through metrics such as attrition, recruitment, retention, consent, adherence rates, and usage frequency. It also seeks to gather initial data on the application's impact on clinical outcomes, including PTSD symptom severity, depressive symptoms, anxiety levels, and quality of life. The procured data will provide information for designing a larger-scale RCT (Randomized Controlled Trial) and underpin subsequent efforts to refine the "TraumaRelief" application.
