Randomized Controlled Trial on the Provision of the EMDR Integrative Group Treatment Protocol Adapted for Ongoing Traumatic Stress to Female Patients With Cancer-Related Posttraumatic Stress Disorder Symptoms

Abstract

This randomized controlled trial extended the investigation previously conducted by Jarero et al. (2015) which found that the eye movement desensitization and reprocessing Integrative Group Treatment Protocol adapted for ongoing traumatic stress (EMDR-IGTP-OTS) was effective in reducing posttraumatic stress disorder (PTSD) symptoms related to the diagnosis and treatment of different types of cancer in adult women. The current study sought to determine if the results could be replicated and if the treatment would also be effective in reducing symptoms of anxiety and depression. Participants in treatment (N = 35) and no-treatment control (N = 30) groups completed pre, post, and follow-up measurements using the Posttraumatic Stress Disorder Checklist for the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) (PCL-5) and the Hospital Anxiety and Depression Scale (HADS). Data analysis by repeated measures analysis of variance (ANOVA) showed that the EMDR-IGTP-OTS was effective in significantly reducing symptoms of PTSD, anxiety, and depression, with symptoms maintained at 90-day follow-up and with large effect sizes (e.g., d = 1.80). A comparison of the treatment and no-treatment control groups showed significantly greater decreases for the treatment group on symptoms of PTSD, anxiety, and depression. No significant correlation was found when exploring the relationship between scores on the Adverse Life Experiences scale and scores indicating pretreatment severity of PTSD, anxiety, and depression. This study suggests that EMDR-IGTP-OTS may be an efficient and effective way to address cancer-related posttraumatic, depressive, and anxious symptoms.
