A multi-site randomized study to compare the effects of Eye Movement Desensitization and Reprocessing (EMDR) added to TAU versus TAU to reduce craving and drinking behavior in alcohol dependent outpatients: study protocol

Diagnosis and Management of Early Stages of ALD

Early forms of alcohol-associated liver disease (ALD) include different stages in the progression of compensated liver disease ranging from steatosis to steatohepatitis and fibrosis. ALD has been classically diagnosed at advanced stages more frequently than other liver diseases. This fact probably contributed to the scarcity of studies on early forms of ALD. Recent studies have investigated the prevalence of early ALD in the general population and have described the natural history of alcohol-induced steatosis and fibrosis, which have been linked to worse prognosis compared with early stages of other chronic liver diseases. In addition, studies on screening and early diagnosis of ALD in at-risk populations have shown that these strategies allow early detection and intervention. Of note, up to 28% of the United States population has concurrent alcohol use and metabolic syndrome, and estimated prevalence of advanced fibrosis among heavy drinkers with metabolic syndrome has increased from 3% in the 1990s to more than 10% in the 2010s. Therefore, new challenges and treatment opportunities will emerge for patients with ALD. In this review, we provide an overview of the state of the art in early ALD, focusing on natural history, diagnosis, and management, and provide insights into future perspectives.

The Effect of Eye Movement Desensitization and Reprocessing (EMDR) Therapy on Reducing Craving in Populations with Substance Use Disorder: A Meta-Analysis

Substance use disorder (SUD) significantly impacts public health, economics, and legal systems worldwide. Eye Movement Desensitization and Reprocessing (EMDR) was initially developed in the late 1980s as a therapeutic approach for post-traumatic stress disorder (PTSD), using bilateral stimulation to integrate traumatic memories with calming physiological responses. However, the effectiveness of EMDR in treating SUD remains unclear. This study aims to conduct a systematic review and meta-analysis of the impact of EMDR therapy on craving reduction in individuals with SUD. The search was conducted using databases such as PubMed and Web of Science, focusing on studies that measured craving and employed EMDR interventions. Both random and fixed effects models were used to pool effect sizes, utilizing an R software meta-package (R-4.4.1). The study adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The results indicated a significant reduction in cravings among patients undergoing EMDR therapy. Specifically, under the fixed effect model, the standardized mean difference (SMD) was -0.866 with a 95% confidence interval ranging from -1.121 to -0.611 (z = -6.66, p < 0.0001). These findings may demonstrate the significant efficacy of EMDR therapy in decreasing cravings in people with SUD.

Feasibility and Efficacy of Addiction-Focused Eye Movement Desensitization Reprocessing in Adults with Substance Use Disorder

PURPOSE

Addiction-focused eye movement desensitization reprocessing (AF-EMDR) is a viable add-on therapy to treat memories that drive addiction cravings. However, little research has explored AF-EMDR and its effects in people with substance abuse disorder (SUD). The purposes of this study were to determine the feasibility of conducting AF-EMDR and to test the preliminary efficacy of AF-EMDR on overall cravings experienced by persons with SUD, craving, perseverations associated with addiction, and irrational cognitions related to addiction.

METHODS

This pilot study used a two-arm randomized controlled trial (RCT) design with an experimental group (AF-EMDR + cognitive behavioral therapy [CBT]) and a control group (CBT Only). Thirty participants were recruited from a residential program or a partial hospitalization program in a recovery center in Florida, from October 2021 through January 2022 and randomly assigned to the experimental group (n = 15) or the control group (n = 15).

RESULTS

All participants adhered to the four-session 60-min AF-EMDR intervention and post-intervention data collection; 98.33% completed all four sessions. Results indicated significant reductions in cravings, perseverative thoughts about substance of choice, and irrational cognitions among participants in both the experimental (AF-EMDR + CBT) and control (CBT Only) groups during the intervention; however, there was no significant difference between groups.

CONCLUSIONS

The results showed positive trends in decreasing craving. However, more clinical trials with a larger sample are necessary to assess the efficacy and sustainability of such effects in persons with SUD.

Principles of Care for Young Adults With Co-Occurring Psychiatric and Substance Use Disorders

Over 50% of young adults (defined as individuals aged 18-25 years) with substance use disorders (SUDs) have at least 1 co-occurring psychiatric disorder, and the presence of co-occurring disorders worsens SUD outcomes. Treatment of both co-occurring psychiatric disorders and SUDs in young adults is imperative for optimal treatment, yet many barriers exist to achieving this goal. We present a series of evidence-informed principles of care for young adults with co-occurring psychiatric disorders derived by a workgroup of experts convened by Boston Medical Center's Grayken Center for Addiction. The 3 principles are as follows: (1) young adults should receive integrated mental health and addiction care across treatment settings; (2) care should be responsive to the needs of young adults exposed to trauma and other adverse childhood experiences; and (3) treatment programs should regularly assess and respond to the evolving mental health needs, motivations, and treatment goals of young adults with co-occurring disorders. Our guidance for each principle is followed by a review of the evidence supporting that principle, as well as practice considerations for implementation. More research among young adults is critical to identify effective treatments and service systems for those with co-occurring disorders.

Addiction-Focused Eye Movement Desensitization and Reprocessing Therapy as an Adjunct to Regular Outpatient Treatment for Alcohol Use Disorder: Results From a Randomized Clinical Trial

BACKGROUND

This study examined the feasibility, safety, and efficacy of addiction-focused eye movement desensitization and reprocessing (AF-EMDR) treatment, as an add-on intervention to treatment as usual (TAU).

METHODS

Adult outpatients with alcohol use disorder (AUD) (N = 109) who already received or had just started with TAU (Community Reinforcement Approach) were recruited at 6 outpatient addiction care facilities. They were randomly assigned to either TAU + 7 weekly 90-minute sessions of AF-EMDR (N = 55) or TAU-only (N = 54). Assessments were made at baseline, after AF-EMDR therapy (+ 8 weeks in the TAU-only group), and at 1- and 6-month follow-up. The primary outcomes were changes in drinking behavior as reported by the participant and biomarker indices.

RESULTS

Data were analyzed as intent-to-treat with linear mixed models. Additionally, sensitivity analyses were performed. No group or interaction effects were found for any of the outcome variables. Only limited change over time was seen with regard to indices of personal and societal recovery and in some secondary indices of clinical recovery (craving, desire thinking, and rumination). Reliable Change Index calculations showed that more TAU-only participants showed clinical improvement with regard to alcohol consumption while a somewhat higher proportion of participants in the TAU + AF-EMDR group experienced less craving. The acceptability, safety, and feasibility of the treatments received in both groups were comparable.

CONCLUSIONS

There was no add-on effect of AF-EMDR on TAU with regard to drinking behavior in outpatients with an AUD. Possible explanations are discussed. Future studies should first establish proof of principle regarding the potential of AF-EMDR therapy to disrupt operant learning and habits relevant in addiction.

Review of EMDR Interventions for Individuals With Substance Use Disorder With/Without Comorbid Posttraumatic Stress Disorder

A large proportion (11%–60%) of people with posttraumatic stress disorder (PTSD) also suffer from substance use disorder (SUD). As the high cooccurrence of PTSD and SUD leads to a worsening of psychopathological severity, development and evaluation of integrated treatments become highly valuable for individuals presenting with both diagnoses. Eye movement desensitization and reprocessing (EMDR) therapy may fit these needs. This article summarized all studies that investigated EMDR treatment for SUD, to clarify whether EMDR might be a useful approach. A comprehensive Title/Abstract/Keyword search was conducted on PsycInfo, PsychArticle, PubMed, and Scopus databases. A total of 135 articles were retrieved, and 8 articles met inclusion/exclusion criteria. One RCT and one case study evaluated trauma-focused EMDR; one clinical RCT, one non-clinical RCT, one cross-over study, and one case study evaluated addiction-focused EMDR; and one quasi-experimental and one multiphase case study evaluated the combination of addiction-focused and trauma-focused EMDR. Results show that EMDR treatment consistently reduces posttraumatic symptoms, but that its effects on SUD symptoms are less evident. Although EMDR should be considered as a promising tool for this population due to its possible potential to improve SUD outcomes, further research is needed to see whether EMDR therapy, either trauma-focused or addiction-focused, is effective for SUD. We conclude with suggestions for future research and clinical practice in this area.

Treatment of Alcohol Use Disorder With Adjunctive Addiction-Focused EMDR: A Feasibility Study

Alcohol use disorder (AUD) treatment presents a serious challenge. While there are evidence-based treatment options available, there is still a substantial group of treatment-seeking patients who do not complete regular AUD treatment. In addition, accomplished reductions in drinking behavior during treatment are often lost posttreatment. Therefore, both feasibility and effectiveness of AUD treatment are important. Innovative interventions, such as addiction-focused eye movement desensitization and reprocessing (AF-EMDR) therapy (Markus & Hornsveld, 2017), may hold promise as adjunctive treatments. Here the results of a feasibility study of adjunctive AF-EMDR therapy in outpatients with AUD and without comorbid posttraumatic stress disorder (PTSD) are described. A multiple baseline design across four participants was used. They received AF-EMDR alongside treatment as usual (TAU). The results suggest that, while challenging, AF-EMDR therapy in outpatients with AUD can be safe, acceptable, and feasible. Whether it is effective, under what conditions and for whom, requires further study however.

EMDR as Add-On Treatment for Psychiatric and Traumatic Symptoms in Patients with Substance Use Disorder

Background: Substance use disorders (SUD) are patterns of substance use leading to severe impairment on social, working and economic levels. In vivo and clinical findings have enhanced the role of the brain's stress-related system in maintaining SUD behaviors. Several studies have also revealed a high prevalence of post-traumatic symptoms among SUD patients, suggesting that a trauma-informed treatment approach could lead to better treatment outcomes. However, only few studies have evaluated the use of eye movement desensitization and reprocessing (EMDR) in SUD without consistent results. The aim of the present pilot study was to assess the efficacy of a combined trauma-focused (TF) and addiction-focused (AF) EMDR intervention in treating post-traumatic and stress-related symptoms of patients with SUD.

Methods: Forty patients with different SUD were enrolled in the study. Twenty patients underwent treatment as usual (TAU), the other 20 patients were treated with TAU plus 24 weekly sessions of EMDR. All patients were assessed before and after intervention for several psychological dimensions using specific tools (i.e., BDI-II, DES, IES-R, STAI, and SCL-90-GSI). A repeated measure MANOVA was performed to evaluate both between groups (TAU + EMDR vs. TAU) and within group (pre- vs. post-intervention) effects and interactions. A secondary outcome was the dichotomous variable yielded by the urine drug testing immunoassay (yes/no).

Results: The RM-MANOVA revealed both a significant pre–post main effect (p < 0.001), and a significant group-by-time main effect (p < 0.001). Significant improvements on IES-R, DES, and SCL-90-GSI scales were shown in both groups according to time effects (p < 0.05). However, significant greater effects were found for TAU + EMDR group than TAU group. No differences were found between TAU and TAU + EMDR groups in terms of urine drug immunoassay results before and after the interventions.

Conclusions: The TAU + EMDR group showed a significant improvement of post-traumatic and dissociative symptoms, accompanied by a reduction in anxiety and overall psychopathology levels, whereas TAU group showed a significant reduction only in post-traumatic symptoms. Although our results can only be considered preliminary, this study suggests that a combined TF- and AF- EMDR protocol is an effective and well-accepted add-on treatment for patients with SUD.

EMDR Therapy Reduces Intense Treatment-Resistant Cravings in a Case of Gamma-Hydroxybutyric Acid Addiction

This article presents the first experiences of using eye movement desensitization and reprocessing (EMDR) therapy to aid in the treatment of gamma-hydroxybutyric acid (GHB) dependency. A case presented itself as a result of intense, treatment-resistant cravings despite pharmacological treatment. The patient received 7 weekly sessions using a subset of the palette of EMDR interventions in addiction (PEIA; Markus & Hornsveld, 2017) targeting both negative and positive valenced addiction-related memory representations from the past, present, and future. Patient-reported GHB craving showed a gradual and prolonged reduction. Urine samples showed that the patient remained abstinent during and at least 6 months after EMDR therapy. Further research regarding the effectiveness of EMDR therapy in this particularly challenging group of substance users is warranted.

Desensitizing Addiction: Using Eye Movements to Reduce the Intensity of Substance-Related Mental Imagery and Craving

Eye movement desensitization and reprocessing (EMDR) is an effective treatment for posttraumatic stress disorder. During this treatment, patients recall traumatic memories while making horizontal eye movements (EM). Studies have shown that EM not only desensitize negative memories but also positive memories and imagined events. Substance use behavior and craving are maintained by maladaptive memory associations and visual imagery. Preliminary findings have indicated that these mental images can be desensitized by EMDR techniques. We conducted two proof-of-principle studies to investigate whether EM can reduce the sensory richness of substance-related mental representations and accompanying craving levels. We investigated the effects of EM on (1) vividness of food-related mental imagery and food craving in dieting and non-dieting students and (2) vividness of recent smoking-related memories and cigarette craving in daily smokers. In both experiments, participants recalled the images while making EM or keeping eyes stationary. Image vividness and emotionality, image-specific craving and general craving were measured before and after the intervention. As a behavioral outcome measure, participants in study 1 were offered a snack choice at the end of the experiment. Results of both experiments showed that image vividness and craving increased in the control condition but remained stable or decreased after the EM intervention. EM additionally reduced image emotionality (experiment 2) and affected behavior (experiment 1): participants in the EM condition were more inclined to choose healthy over unhealthy snack options. In conclusion, these data suggest that EM can be used to reduce intensity of substance-related imagery and craving. Although long-term effects are yet to be demonstrated, the current studies suggest that EM might be a useful technique in addiction treatment.
