ICBT and IEMDR-FT for Mental Health in Breast Cancer Patients

Overview

This study aims to compare the effectiveness of two internet-based therapy approaches in improving psychological well-being and reducing distress among patients diagnosed with breast cancer. Participants will be randomly assigned to one of two groups: a 7-week internet-based Cognitive Behavioral Therapy (iCBT) program or a 3-session internet-based Eye Movement Desensitization and Reprocessing Flash Technique (iEMDR-FT) within a week. Both interventions will be delivered online in a group format under the guidance of experienced therapists. Participants' mental health status-including anxiety, depression, traumatic stress, fear of cancer recurrence, and overall quality of life-will be assessed before the intervention, immediately after completion, and again at a 3-month follow-up. The results of this study are expected to provide valuable insights into how digital psychotherapy methods can help breast cancer patients cope with emotional challenges during their treatment. The findings will also inform the development of future online psychosocial support models in oncology.

Breast cancer is widely considered a complex condition that entails profound psychological repercussions alongside physical challenges. In addition to the stress of undergoing medical treatments, many patients develop an intense fear of cancer recurrence (FCR), depressive and anxious states, and symptoms that may meet the criteria for posttraumatic stress disorder (PTSD). Given these extensive emotional burdens, structured psychological interventions have emerged as vital components of comprehensive oncological care. While Cognitive Behavioral Therapy (CBT) is established as the gold standard for reducing anxiety and depression, emerging trauma-focused therapies-such as Eye Movement Desensitization and Reprocessing (EMDR)-are increasingly recognized for their efficacy in addressing cancer-related traumatic stress. Among EMDR-based interventions, the Flash Technique (FT) represents an innovative adaptation designed to minimize the discomfort of processing traumatic memories. Unlike traditional EMDR protocols, which may require individuals to recall and discuss disturbing events in detail, the Flash Technique uses brief exposures to distressing imagery, followed by rapid bilateral stimulation and positive recall. These "flashes" can quickly desensitize the emotional intensity of cancer-related memories while reducing the risk of re-traumatization. Early studies on the Flash Technique have shown promise in alleviating traumatic symptoms in non-cancer populations, highlighting the method's potential to offer quick, effective relief from emotionally charged recollections. However, there is a notable lack of research exploring its efficacy specifically in patients with breast cancer. This randomized controlled trial (RCT) is the first known study to directly compare the Flash Technique, adapted for online delivery (iEMDR-FT), with an internet-based CBT program (iCBT) in breast cancer patients. Participants are randomly assigned to one of two groups: a 7-week iCBT program or a 3-session iEMDR-FT protocol. The iCBT program focuses on cognitive restructuring, stress management, and emotional regulation skills tailored to address the unique challenges of cancer-related thought patterns (e.g., catastrophic thinking, fear of recurrence). In contrast, the iEMDR-FT group engages in low-intensity trauma processing, wherein participants briefly recall cancer-related distressing scenes, then undergo sets of rapid bilateral stimulation combined with positive imagery ("flash" sets). This approach aims to swiftly reduce traumatic arousal without requiring the prolonged confrontation of painful memories often associated with traditional trauma therapies. Both interventions are delivered online in a group format, guided by experienced therapists. Assessments include measures of posttraumatic stress (PCL-5), fear of cancer recurrence, depression-anxiety-stress (DASS-21), and quality of life (WHOQOL-BREF). Data are collected at baseline, immediately post-intervention, and three months post-intervention to evaluate both immediate and sustained changes in participants' mental health status. By comparing these two distinct therapeutic modalities, the study seeks to determine whether the rapid, minimal-exposure Flash Technique offers advantages over-or is equivalent to-the more extended, structured cognitive framework of CBT. The outcomes of this investigation may fill a critical gap in the current literature by clarifying the practical utility, safety, and acceptability of online EMDR Flash Technique in an oncology setting. If iEMDR-FT proves to be equally effective or superior to iCBT in reducing traumatic stress, fear of cancer recurrence, and emotional distress, it could represent a valuable, time-efficient option for treating psychological sequelae in breast cancer. Conversely, if iCBT demonstrates better long-term gains in certain domains-such as cognitive restructuring of illness-related beliefs-this will inform clinicians about the relative strengths of each intervention. Ultimately, this study is poised to provide evidence-based guidance for mental health professionals and oncology teams in selecting or integrating internet-based interventions, thereby contributing to more flexible and patient-centered psychosocial care for individuals coping with breast cancer.
