Eye movement desensitization of public-speaking anxiety: a partial dismantling

EMDR as Treatment Option for Conditions Other Than PTSD: A Systematic Review

Eye Movement Desensitisation and Reprocessing (EMDR) is a treatment for post-traumatic stress disorder (PTSD). The technique is known to facilitate reprocessing of maladaptive memories that are thought to be central to this pathology. Here we investigate if EMDR therapy can be used in other conditions. We conducted a systematic literature search on PubMed, ScienceDirect, Scopus, and Web of Science. We searched for published empirical findings on EMDR, excluding those centred on trauma and PTSD, published up to 2020. The results were classified by psychiatric categories. Ninety articles met our research criteria. A positive effect was reported in numerous pathological situations, namely in addictions, somatoform disorders, sexual dysfunction, eating disorders, disorders of adult personality, mood disorders, reaction to severe stress, anxiety disorders, performance anxiety, Obsessive-Compulsive Disorder (OCD), pain, neurodegenerative disorders, mental disorders of childhood and adolescence, and sleep. Some studies reported that EMDR was successful in usually uncooperative (e.g., Dementia) or unproductive cases (e.g., aphasia). Moreover, in some severe medical conditions, when psychological distress was an obstacle, EMDR allowed the continuation of treatment-as-usual. Furthermore, the effects observed in non-pathological situations invite for translational research. Despite a generally positive outlook of EMDR as an alternative treatment option, more methodologically rigorous studies are needed. We discuss the advantages and limitations and possible implications for the hypothesised mechanisms of action.

The effectiveness of eye movement desensitization and reprocessing toward anxiety disorder: A meta-analysis of randomized controlled trials

BACKGROUND

Eye Movement Desensitization and Reprocessing (EMDR) has been well established as an effective treatment for post-traumatic stress disorder (PTSD). However, PTSD has been re-categorized as part of trauma and stressor-related disorders instead of anxiety disorders. We conducted the first meta-analysis on Randomized Controlled Trials to evaluate the effectiveness of EMDR on reducing symptoms of anxiety disorders.

METHODS

A manual and systematic search using various databases and reference lists of systematic review articles published up to December 2018 was conducted. The symptoms of anxiety, phobia, panic, traumatic feelings and behaviors/somatic symptoms were examined. Hedges' g effect sizes were computed, and random effect models were used for all analyses.

RESULTS

A total of 17 trials with 647 participants were included in this meta-analysis. EMDR was associated with a significant reduction of anxiety (g = -0.71; 95% CI: -0.96 to -0.47), panic (g = -0.62; 95% CI: -1.10 to -0.14), phobia (g = -0.45; 95% CI: -0.81 to -0.08), behavioural/somatic symptoms (g = -0.40; 95% CI: -0.63 to -0.12), but not traumatic feelings (g = -0.48; 95% CI: -1.14 to -0.18). Subgroup analysis revealed greater effects of EMDR if compared to passive control. However, the effects were not significantly different based on the duration, number of therapy sessions, or the number of weekly sessions.

CONCLUSIONS

Our meta-analysis indicates that EMDR is efficacious for reducing symptoms of anxiety, panic, phobia, and behavioural/somatic symptoms. Further research is needed to explore EMDR's long term efficacy on anxiety disorders.

Psychological Interventions for the Fear of Public Speaking: A Meta-Analysis

Background: Fear of Public Speaking (FoPS) or public speaking anxiety is a type of social anxiety and the single most commonly feared situation in the population. FoPS is disabling with negative occupational, academic, and social consequences, reported by up to one third of the population. FoPS in adolescence and adulthood is associated with an increased risk of developing generalized social anxiety disorder with further impairments. Since the last review on FoPS, a significant number of randomized controlled trials (RCTs) have been conducted assessing the effects of novel interventions with innovative modes of delivery.

Objectives: The objectives of the present meta-analysis are to (1) examine the short and long-term effects of psychological interventions aimed at FoPS on FoPS and generalized social anxiety; (2) assess whether differences exist between technology-assisted modes of delivery (e.g., Internet-delivered therapies) and more traditional modes of delivering treatment (e.g., face-to-face therapies); (3) investigate whether differences in effect exist between theoretical frameworks; (4) inspect the differences in effect size between self-report measures and other measures (i.e., physiological and behavioral); (5) examine the effects of psychological interventions aimed at FoPS on secondary outcome measures (e.g., depression); and (6) investigate whether a “sleeper effect” is present for psychological interventions for FoPS and generalized social anxiety.

Methods: The study investigates the effects of psychological interventions for FoPS through a quantitative meta-analysis of RCTs, using a random-effects model.

Results: A total of 30 RCTs with 1,355 participants were included through systematic searches of PsycINFO, MEDLINE, Web of Science, and Cochrane Library. The majority of the studies investigated the effects of cognitive or behavioral interventions. Nearly half of the studies used active control groups (e.g., attention placebo), whereas the other half used passive (e.g., waitlist) controls. The overall effect of psychological interventions for FoPS across 62 interventions was 0.74 (Hedges g; 95% CI: 0.61–0.87) with low to moderate heterogeneity. No difference in effect was found across theoretical frameworks. The effects based on self-report measures were larger compared to physiological and behavioral outcomes. Effects were robust against both active and passive control groups. Furthermore, psychological interventions for FoPS had a small to moderate effect on generalized social anxiety disorder (g = 0.35; 95% CI: 0.22–0.48). The effect of psychological interventions aimed at FoPS at follow-up was large (g = 1.11, 95% CI: 0.90–1.31) and moderate to large for generalized social anxiety (g = 0.70, 95% CI: 0.59–0.80). A sleeper effect was found for cognitive and behavioral interventions, indicating that patients continued to improve after treatment termination. There were some indications of publication bias.

Conclusions: Psychological interventions are effective in reducing FoPS. Interventions using technology-assisted modes of delivery are equally effective as traditional face-to-face interventions in reducing FoPS. This finding highlights an opportunity to increase access to evidence-based treatments through technology-delivered interventions, which can be implemented at schools, in primary care and specialist mental health care. Moreover, psychological interventions aimed at FoPS have an effect on generalized social anxiety. Further implications are discussed.

Comparing the Effectiveness of EMDR and TF-CBT for Children and Adolescents: a Meta-Analysis

Efficacy of EMDR and TF-CBT for posttraumatic stress symptoms (PTSS) was explored through meta-analysis. A comprehensive search yielded 494 studies of children and adolescents with PTSS who received treatment with these evidence-based therapeutic modalities. Thirty total studies were included in the meta-analysis. The overall Cohen's d was small (-0.359) and statistically significant (p < 0.05), indicating EMDR and TF-CBT are effective in treating PTSS. Major findings posit TF-CBT is marginally more effective than EMDR; those with sub-clinical PTSS responded more favorably in treatment than those with PTSD; and greater reductions in PTSS were observed with presence of comorbidity in diagnosis. Assessment of publication bias with Classic fail-safe N revealed it would take 457 nonsignificant studies to nullify these findings.

EMDR as a Treatment for Test Anxiety

We assigned sixty-two test-anxious undergraduates to eye movement desensitization and reprocessing (EMDR), rational emotive therapy (RET), and information only, which were administered in a single session by trained, “blind” therapists. At posttest, EMDR was most effective in reducing distress whereas RET decreased global test anxiety more than information only. These results may reflect the differential impact of EMDR and RET on verbalized distress and on combined affective and cognitive dimensions of test anxiety, respectively. Perceptions of therapist credibility and helpfulness of treatment moderated the results. We discuss the clinical and research implications of these findings.

An Integrative Model for the Neural Mechanism of Eye Movement Desensitization and Reprocessing (EMDR)

Since the seminal report by Shapiro that bilateral stimulation induces cognitive and emotional changes, 26 years of basic and clinical research have examined the effects of Eye Movement Desensitization and Reprocessing (EMDR) in anxiety disorders, particularly in post-traumatic stress disorder (PTSD). The present article aims at better understanding EMDR neural mechanism. I first review procedural aspects of EMDR protocol and theoretical hypothesis about EMDR effects, and develop the reasons why the scientific community is still divided about EMDR. I then slide from psychology to physiology describing eye movements/emotion interaction from the physiological viewpoint, and introduce theoretical and technical tools used in movement research to re-examine EMDR neural mechanism. Using a recent physiological model for the neuropsychological architecture of motor and cognitive control, the Threshold Interval Modulation with Early Release-Rate of rIse Deviation with Early Release (TIMER-RIDER)-model, I explore how attentional control and bilateral stimulation may participate to EMDR effects. These effects may be obtained by two processes acting in parallel: (i) activity level enhancement of attentional control component; and (ii) bilateral stimulation in any sensorimotor modality, both resulting in lower inhibition enabling dysfunctional information to be processed and anxiety to be reduced. The TIMER-RIDER model offers quantitative predictions about EMDR effects for future research about its underlying physiological mechanisms.

A meta-analysis of the contribution of eye movements in processing emotional memories

BACKGROUND AND OBJECTIVES

Eye Movement Desensitisation and Reprocessing (EMDR) is now considered evidence based practice in the treatment of trauma symptoms. Yet in a previous meta-analysis, no significant effect was found for the eye movement component. However methodological issues with this study may have resulted in a type II error. The aim of this meta-analysis was to examine current published studies to test whether eye movements significantly affect the processing of distressing memories.

METHOD

A systematic review of the literature revealed two groups of studies. The first group comprised 15 clinical trials and compared the effects of EMDR therapy with eye movements to those of EMDR without the eye movements. The second group comprised 11 laboratory trials that investigated the effects of eye movements while thinking of a distressing memory versus the same procedure without the eye movements in a non-therapy context. The total number of participants was 849.

RESULTS

The effect size for the additive effect of eye movements in EMDR treatment studies was moderate and significant (Cohen's d = 0.41). For the second group of laboratory studies the effect size was large and significant (d = 0.74). The strongest effect size difference was for vividness measures in the non-therapy studies (d = 0.91). The data indicated that treatment fidelity acted as a moderator variable on the effect of eye movements in the therapy studies.

CONCLUSIONS

Results were discussed in terms of current theories that suggest the processes involved in EMDR are different from other exposure based therapies.

Dosed versus prolonged exposure in the treatment of fear: an experimental evaluation and review of behavioral mechanisms

Exposure-based treatments have proven effective in treating a range of fears and phobias and can be accounted for by mechanisms described in behavioral theory. Enhanced dosed and dosed-only exposure are promising new behavioral approaches for treating fears and phobias. Thirty-nine participants with speech anxiety were randomly assigned to a prolonged exposure (PE) condition, a positively enhanced dosed exposure (PDE) condition, a dosed-only exposure (DE) condition, or a negatively-supplemented dosed exposure (NDE) condition. Results indicated that both the PDE and DE conditions produced less measured aversive arousal and significantly more rapid arousal reduction than the tested alternatives. These techniques may represent an important advancement, in that the treatment gains of traditional exposure therapies might be achieved without the degree of aversive arousal (and possibly high drop out rates) typically seen in exposure therapies. Additionally, these data contradict prevailing opinion concerning the necessity for sustained aversive arousal during exposure-based treatment.

Specific and nonspecific treatment factors in the experimental analysis of behavioral treatment efficacy

Interest in the empirical demonstration of the clinical efficacy of psychosocial treatments has been rekindled by societal concerns over accountability and cost-effectiveness in the delivery of mental health services. Behavior therapy has had a long history of experimental research on treatment efficacy and enjoys a visible presence in contemporary mental health practice. The demonstration of behavioral treatment efficacy, however, requires experimental evidence that shows the efficacy of prescriptive structured procedures beyond nonspecific factors in delivery of such procedures. The authors provide an analysis of the nature of nonspecific treatment factors and nonspecific effects and suggest experimental procedures testing the incremental validity of specific treatments. They examine two widely promoted, prescriptive structured treatments to analyze the specificity of their clinical efficacy: eye movement desensitization and reprocessing for anxiety disorders and cognitive-behavioral treatment of generalized anxiety disorder. They conclude that the treatments show different levels of efficacy and different degrees of specificity.

Alternative psychotherapy approaches for social anxiety disorder

Alternative therapies and therapy modalities for SAD are needed because: Established treatments (CBT and pharmacologic) do not help everyone who seeks help. Established treatments provide only partial decrease in symptoms for many patients. Patients may experience recurrence of symptoms in long-term follow-up. CBT does not reach enough patients in need. Alternative treatment approaches and modalities may also be needed to address the successful outcomes of CBT. Success in overcoming social anxiety symptoms can generate a whole new set of challenges. For example, a 31-year-old man who overcomes his fear of dating and begins his first romantic relationship may need a less symptomatically focused therapy to deal with issues that arise in this relationship. Likewise, a woman whose decreased social anxiety enables her to get a long-awaited promotion may need to deal with the stress of adjusting to her new responsibilities. An individual who overcomes phobia of public speaking and still has mild anxiety may need to graduate to a forum such as Toastmasters to provide continued exposure to further develop confidence and skills in public speaking.

Eye movement desensitization and reprocessing (EMDR): a meta-analysis

Eye movement desensitization and reprocessing (EMDR), a controversial treatment suggested for posttraumatic stress disorder (PTSD) and other conditions, was evaluated in a meta-analysis of 34 studies that examined EMDR with a variety of populations and measures. Process and outcome measures were examined separately. and EMDR showed an effect on both when compared with no treatment and with therapies not using exposure to anxiety-provoking stimuli and in pre post EMDR comparisons. However, no significant effect was found when EMDR was compared with other exposure techniques. No incremental effect of eye movements was noted when EMDR was compared with the same procedure without them. R. J. DeRubeis and P. Crits-Christoph (1998) noted that EMDR is a potentially effective treatment for noncombat PTSD. but studies that examined such patient groups did not give clear support to this. In sum, EMDR appears to be no more effective than other exposure techniques, and evidence suggests that the eye movements integral to the treatment, and to its name, are unnecessary.

Using EMDR to treat post-traumatic stress disorder in a prison setting

This article describes the treatment of a young man who developed post-traumatic stress disorder (PTSD) following the sudden unexpected miscarriage of his unborn child. He was diagnosed with this anxiety disorder while serving a term of imprisonment. He was treated with a controversial psychological treatment for PTSD, eye movement desensitisation reprocessing (EMDR) therapy, during one, 1-hour session. After this session, his progress was monitored by a further three follow-up appointments at 1 week, 1 month and 3 months, where the self-report questionnaires were repeated and compared with pre-treatment scores. These demonstrated improvement post-treatment and at a 3-month follow-up session. The discussion arising from the treatment will concentrate on EMDR as an effective treatment for PTSD, particularly within a prison setting. Data from recent research highlight the potential risks of PTSD within a community population and the implications for midwives and nurses who treat and care for traumatized patients are discussed.

The cognitive dismantling of Eye Movement Desensitization and Reprocessing (EMDR) treatment of Posttraumatic Stress Disorder (PTSD)

Twenty-seven subjects were exposed to standard Eye Movement Desensitization and Reprocessing (EMDR) treatment or a similar treatment without the explicit cognitive elements found in EMDR. Standardized psychometric assessments were administered (Structured Interview for Post Traumatic Stress Disorder, Impact of Event Scale, Revised Symptom Checklist-90) by independent assessors at pretest, posttest and two separate follow-up periods. Potential subjects met specific inclusion/exclusion criteria. Subjective measures including Subjective Units of Disturbance and Validity of Cognition assessments were also conducted. A two-factor repeated measures analysis of variance revealed that both treatments produced significant symptom reductions and were comparable on all dependent measures across assessment phases. The present findings are discussed in light of previous dismantling research that converges to suggest that several elements in the EMDR protocol may be superfluous in terms of the contribution to treatment outcome. These same elements have nevertheless entered unparsimoniously into consideration as possible explanatory variables.

Does EMDR work? And if so, why?: a critical review of controlled outcome and dismantling research

Research on Eye Movement Desensitization and Reprocessing therapy (EMDR) was reviewed to answer the questions "Does EMDR work?" and "If so, Why?" This first question was further subdivided on the basis of the control group: (a) no-treatment (or wait list control), (b) nonvalidated treatments, and (c) other validated treatments. The evidence supports the following general conclusions: First, EMDR appears to be effective in reducing at least some indices of distress relative to no-treatment in a number of anxiety conditions, including posttraumatic stress disorder, panic disorder, and public-speaking anxiety. Second, EMDR appears at least as effective or more effective than several nonvalidated treatments (e.g., relaxation, active listening) for posttraumatic stress reactions. Third, despite statements implying the contrary, no previously published study has directly compared EMDR with an independently validated treatment for posttraumatic stress disorder (e.g., therapist-directed flooding). In the treatment of simple phobia, participant modeling has been found to be more effective than EMDR. Fourth, our review of dismantling studies reveals there is no convincing evidence that eye movements significantly contribute to treatment outcome. Recommendations regarding further research directions are provided.

Eye Movement Desensitization and Reprocessing: an analysis of specific versus nonspecific treatment factors

Incremental validity and incremental efficacy have become important issues in the evaluation of psychological assessment and intervention procedures. Incremental validity in assessment is that shown by novel measures over and above established ones. Incremental efficacy is that shown by novel treatments over and above nonspecific and established treatment effects. In this paper, we critically examine the question of whether Eye Movement Desensitization and Reprocessing (EMDR) possesses efficacy above and beyond nonspecific treatment effects and components that are shared with well-established interventions. A review of recently published efficacy studies reveals that (a) the effects of EMDR are largely limited to verbal report indices, (b) eye movements and other movements appear to be unnecessary, and (c) reported effects are consistent with nonspecific treatment features. Examination of individual studies shows that control procedures for nonspecific features have been minimal. We analyze EMDR for nonspecific treatment features and suggest experimental controls to examine the incremental efficacy of EMDR.

The contributions of eye movements to the efficacy of brief exposure treatment for reducing fear of public speaking

The present study was designed to isolate the effects of the eye-movement component of the Eye Movement Desensitization and Reprocessing (EMDR) procedure in the treatment of fear of public speaking. Seventy-one undergraduate psychology students who responded in a fearful manner on the Fear Survey Schedule II and on a standardized, self-report measure of public speaking anxiety (Personal Report of Confidence as a Speaker; PRCS) were randomly assigned to one of four groups in a 2x2 factorial design. The two independent variables assessed were treatment condition (imagery plus eye movements vs. imagery alone) and type of imagery (fear-relevant vs. relaxing). Dependent variables assessed were self-reported and physiological anxiety during exposure and behavioral indices of anxiety while giving a speech. Although process measures indicated exposure to fear-relevant imagery increased anxiety during the procedure, no significant differences among groups were found on any of the outcome measures, except that participants who received eye movements were less likely to give a speech posttreatment than participants who did not receive eye movements. Addition of the eye movements to the experimental procedure did not result in enhancement of fear reduction. It was concluded, consistent with the results of past research, that previously reported positive effects of the EMDR procedure may be largely due to exposure to conditioned stimuli.
