There is a growing body of literature on the treatment strategy of posttraumatic stress disorder(PTSD). And metaanalyses and clinical guidelines continue to emerge. Recently, trauma-focused CBT or EMDR have been recommended for the 1st line of therapy for this population. However, very little literature exists for combined treatment of medication and psychotherapy in PTSD. This case report introduces two individuals with PTSD, who had initially failed to respond to antidepressant therapy, but later improved after EMDR was added. Further controlled studies are needed to generalize this finding.

Abstract:
Very little is known about the mechanisms that underlie the therapeutic effectiveness of eye movement desensitization and reprocessing (EMDR). This study tested whether the content of participants' responses during EMDR is similar to that thought to be effective for traditional exposure treatments (reliving), or is more consistent with distancing, which would be expected given Shapiro's proposal of dual process of attention. The responses made by 44 participants with PTSD were examined during their first EMDR treatment session. An independent rater coded these responses according to whether they were consistent with reliving, distancing, or focusing on material other than the primary trauma. The coding system was found to have satisfactory inter-rater reliability. Greatest improvement on a measure of PTSD symptoms occurred when the participant processed the trauma in a more detached manner. Cross-lagged panel correlations suggest that processing in a more detached manner was a consequence of the EMDR procedure rather than a measure that covaried with improvement. [Author Abstract]

Abstract:
This article provides an overview of selective issues relating to adult posttraumatic stress disorder (PTSD) and its treatment with eye movement desensitization and reprocessing (EMDR). The article begins by providing a historical overview of PTSD, and debates about the etiology and definition of PTSD are discussed. The most predominant theories of PTSD are summarized by highlighting how they have evolved from traditional behavioral accounts based on the assumption that PTSD is an anxiety disorder to theories that now incorporate information-processing models. This article then examines the development of EMDR and the corresponding body of research that clearly demonstrates its efficacy for the treatment for adult PTSD. The underlying mechanisms of EMDR are discussed, with a focus on the importance of the eye movement component and how the therapeutic processes in EMDR differ from those of traditional exposure therapy. Finally, the adaptive information-processing (AIP) model that underlies EMDR is outlined, and evidence for the model is summarized. The article concludes by suggesting future research based on questions raised about PTSD and its treatment with EMDR when the AIP model is compared to other information-based theories of PTSD.

Abstract:
Chris was a 44-year old woman who had extremely low self-esteem, depression, panic attacks, and symptoms of dissociation when she began EMDR-facilitated therapy. Eye movement was used initially to reinforce healthy beliefs, physical sensations, and feelings related to experiences of safety, competence, well-being, and success based on prior learning. EMDR was then employed to target painful memories of childhood scenes with her parents, as well as erroneous beliefs and feelings of intense anxiety. Although none of the memories targeted occurred before age 5, the "white empty feeling" that was targeted seemed to represent the earlier deprivation. The desired positive cognition "I am significant" became the "umbrella cognition" containing various "sub-cognitions" (such as "I am loveable," "I deserve respect," and "I can take care of my needs").As Chris reprocessed traumatic childhood memories with EMDR, more and more of these sub-cognitions were integrated. Progress was not linear, but reprocessing the client's issues as she presented them gradually led to a more stable, flexible, and resilient sense of self. Eventually, the negative self-assessments dissipated. After 18 sessions Chris felt strong and confident, fully present, and eager to be involved in intimate relationships that were based on mutual respect. [Text, pp. 215-216] [Pilots]

Abstract:
Very little is known about the mechanisms that underlie the effectiveness of EMDR. Participants will be presented with information to
facilitate their understanding of two competing hypotheses to account for EMDR effectiveness. Namely, because it uses similar processes found effective in traditional exposure treatments (reliving). Alternaitvely according to Shapiro's proposal of dual process of attention, the procedure may be successful because it elicits distancing responses. Participants will be able to describe how these competing hypotheses were investigated. The responses made by 44 participants with Post Traumatic Stress Disorder (PTSD) were examined during their first EMDR treatment session. Participants will be able to describe the key process variable found to be effective in EMDR treatment of trauma memories and the extent to which this process is determined by eye movement or by therapist instructions.

Abstract:
Introduction:
Treatment of choice for post-traumatic stress disorder (PTSD) is either eye movement desensitization and reprocessing (EMDR) or trauma-focused cognitive behaviour therapy (TFCBT).
Objective:
The aim of the present meta-analysis was to determine whether there are any differences between these two treatments with respect to efficacy and efficiency in treating PTSD.
Method:
We performed a comprehensive literature search using several electronic search engines as well as manual searches of other review papers. Eight original studies involving 227 participants were identified in this manner.
Results:
There were no differences between EMDR and TFCBT on measures of PTSD. However, there was a significant advantage for EMDR over TFCBT in reducing depression (Hedge's g = 0.63). The analysis also indicated a difference in the prescribed homework between the treatments. Meta-regression analyses were conducted to examine the relationship between hours of homework and gains in depression and PTSD symptoms.
Conclusion: These findings are discussed in terms of efficacy and cost-effectiveness and the use of homework in therapy.

Language: English
Format: Journal
Abstract:
This study investigated the benefits of eye movement similar to that used in eye movement desensitization and reprocessing (EMDR) on reducing the vividness and emotionality of negative autobiographical memories. It was hypothesized, based on the working memory model, that any task that disrupts working memory would reduce the vividness and emotionality of distressing memories. In addition, it was predicted that the more visual a memory, the greater the reduction in vividness by a concurrent visual task over an auditory task (counting). Thirty-six nonclinical participants were asked to recall an unpleasant autobiographical memory while performing each of three dual-attention tasks: eye movement, listening to counting, or control (short exposure). Results showed that vividness and emotionality ratings of the memory decreased significantly after eye movement and counting, and that eye movement produced the greatest benefit. Furthermore, eye movement facilitated greater decrease in vividness irrespective of the modality of the memory. Although this is not consistent with the hypothesis from a working memory model of mode-specific effects, it is consistent with a central executive explanation. Implications for enhancing exposure treatment for posttraumatic stress disorder (PTSD) are discussed.

This special issue of the Journal of EMDR Practice
and Research contains a number of articles that address
preliminary issues related to these complex
questions. There are two research studies: a study
investigating the physiological effects of EM (Sack

components of autobiographical memory (Maxfi eld
et al.) . There are several articles by researchers who
have summarized their fi ndings and provided a theoretical
perspective on related issues (Lee; Propper &
Christman; Sondergaard & Elofsson; Stickgold). Two
theoretical articles propose neurobiological and other
mechanisms of action (Bergmann; Solomon & Shapiro
). All these articles make a real contribution to our
conceptualizations of EMDR mechanisms. It is our
hope and intention that this issue will stimulate thinking,
and provide ideas and models for future research,
with the expectation that fi ndings will help to guide
and direct clinical practice. (Excerpt)

Abstract:
EMDR is the most effctive (Ho & Lee, 2012) and efficient (Greenwald et al, 2012) of the established trauma treatments and it is well tolerated by clients. However, EMDR is complex, making dissemination challenging and expensive (Greenwald, 2066a). PC is simplet, more qickly learned, and had shown promise in case stuidies (Greenwald, 2008a, 2008b) and open trials (Greenwald & Schmidt, 2010). If PC is comprable to EMDR, then dissemination of top-tier trauma treatment can be more economical.

Language: English
Format: Journal
Abstract:
The processes that underlie the effectiveness of eye movement desensitization and reprocessing (EMDR)
are examined by evaluating the procedural differences between it and exposure therapy. Major factors
include the degree of emphasis placed on reliving versus distancing in the therapies and the degree to
which clients are encouraged to focus on direct trauma experiences versus experiences associated with
the trauma. Research results indicate that, unlike traditional imaginal exposure, reliving responses in
EMDR did not correlate with symptom improvement. Instead, consistent with an information processing
model, the degree of distancing in EMDR was significantly associated with improvement. A case study
is described to highlight these methodological divergences in the respective therapies relating to reliving.
Finally, the research regarding the possible sources of the distancing response within EMDR was
examined. The results indicate that the distancing process was more likely to be an effect produced by
eye movements than by any therapist instructions. Theoretical and research evaluations indicate that the
mechanisms underlying EMDR and traditional exposure therapy are different.

Abstract:
Objectives: There has been a continued
debate regarding the role of eye movements in Eye Movement
Desensitization and Reprocessing (EMDR). This study examined
the possible autonomic effect of horizontal eye movements after
being exposed to fearful stimuli. Methods: Fifty two healthy
adult women were randomly allocated to eye movement or eye
fixed groups after watching a five minute fear-inducing film clip.
ECG was recorded during the resting state, after watching the
clip, and the treatment. A spectral power analysis of the heart
rate variability was performed. As the variables violated the rule
of normal distribution and the number in each group is small
the non-parametric test was used. Results: Overall, we did not find the differences between the groups in both time and
frequency domains. Some minor differences found were not
consistent with results from previous studies. Conclusions:
Effect of eye movement on autonomic nervous system during fear
desensitization was not supported in this experiment. Further study
with other psychophysiological measures is needed to understand
the role of eye movements in treatment of traumatic memory.

Abstract:
The effectiveness of components of eye movement desensitization and reprocessing (EMDR) was tested by randomly assigning 48 participants to either an eye movement or an eye stationary condition and to one of two types of therapist instructions (reliving or distancing). Participants were university students (mean age 23) who were asked to recall a personal distressing memory with measures of distress and vividness taken before and after treatment, and at follow-up. There was no significant effect of therapist's instruction on the outcome measures. There was a significant reduction in distress for eye movement at post-treatment and at follow-up but overall no significant reduction in vividness. Post hoc analysis revealed a significant reduction in vividness only for the eye movement and distancing instruction condition. The results were consistent with other evidence that the mechanism of change in EMDR is not the same as traditional exposure.

Language: English
Format: Journal
Abstract:
Objectives: The eye movement (EM) has been reported to play a role in enhancing the retrieval of episodic memories and reducing effects of fearful episodes in the past and worries for the futures. However, it is still unclear in the mechanism of EM in normal subjects. We examined the horizontal eye movement (HEM) effect using an aiding apparatus on mental health indices including negative and positive psychological factors, and psychophysiological measures such as heart rate variability and quantitative electroencepaholography (qEEG) in healthy subjects.
Methods: Twenty eight healthy subjects were recruited and randomly allocated into two groups : active HEM group and control group. The active HEM group conducted the HEM training with usual stress management audio-intervention using the apparatus inducing eye movement once a day for 14 days. The control group also conducted the same training once a day for 14 days, however, the saccadic eye movement was not included in this training. Psychological measurements, neurocognitive function tests, heart rate variability measurement and qEEG were conducted before and after the training in both groups.
Results: In the active HEM group, sleep status using Sleep Quality Scale (SQS) positive factors significantly increased after the training. By contrast, scores on the negative items of Psychological Well-Being Scale (PWBS), and negative items of the Life Orientation Test-Revised (LOT-R) were significantly decreased after the training. The percentage of delta amplitude (1-3 Hz) in qEEG significantly decreased after the HEM training. The percentage of alpha amplitude (8-12 Hz) significantly increased after HEM training. The change of delta amplitude in the active HEM group was positively correlated with the change of sleep satisfaction of Visual Analogue Scale (VAS), and the change of alpha amplitude was negatively correlated with depression of VAS, anxiety of VAS and Beck Anxiety Inventory (BAI).
Conclusions: The HEM training improved sleep quality and well-being, and sense of optimism. The HEM training also increased alpha amplitude and decreased delta amplitude in qEEG. The qEEG changes were well correlated with subjective improvement of mental health indices in healthy subjects. These results suggest some evidences that HEM training using the apparatus that induces EM would be helpful in improving subjective mental health in healthy subjects. Further study with larger samples size would be needed.

Format: Dissertation/Thesis
Abstract:
The first aim of this thesis was to describe the characteristics of Posttraumatic Stress Disorder (PTSD) and to elucidate its place as a symptom disorder that sometimes develops when people are exposed to a traumatic event. The current major theoretical approaches to account for why some people who are exposed to trauma develop PTSD and the mechanisms by which this occurs were described. Three classes of theories were reviewed: conditioning/learning approach; information processing theories with a particular focus on the meaning of the trauma event; and biological models with an emphasis on recent neurocircuitry and neurochemistry models.
Successful treatment approaches were then reviewed which indicated two major contenders for the most efficacious treatment for PTSD: traditional cognitive behaviour therapies (CBT) using either stress inoculation or prolonged exposure; and eye movement desensitisation and processing (EMDR). Prior to the first study (Lee, Gavriel, Drummond, Richards, and Greenwald, 2002), a review of the literature indicated equivalent effects for EMDR and CBT. There had been very few direct comparison studies and each had serious methodological flaws, particularly with respect to random assignment and treatment fidelity. Therefore, the first study ensured adequate attention to these areas and involved a direct comparison between the two procedures using a sample of 24 participants diagnosed with PTSD. EMDR and stress inoculation training with prolonged exposure were found to lead to similar symptom improvement at the end of treatment, apart from a slight advantage for EMDR on intrusion symptoms. Both treatments led to significantly greater symptom reduction than a wait list control condition. At follow-up, EMDR led to greater gains on both self-report and observer rated measures of PTSD and self-report measures of depression. Overall, the findings were similar to those described in previously published studies, with a suggestion that EMDR was slightly more efficient than the standard CBT approach.
Given that the evidence suggested that EMDR was a more efficient treatment, it became critical to understand the underlying processes. A process study was undertaken that examined the responses of people with PTSD receiving EMDR treatment (Lee, Taylor, and Drummond, 2006). Guided by process studies of other treatments and theories that might account for why EMDR is effective, participants' responses were examined to see which models better accounted for symptom improvement. The main analysis tested whether or not the responses were consistent with processes that occurred during traditional CBT treatment, which prior research had identified as reliving, or whether they were more consistent with Shapiro's proposal that enhanced information processing occurs because there is a dual focus of attention (that is, the person simultaneously focuses on an external stimulus and on the traumatic memory) (Shapiro, 1995). The responses made by 44 participants were coded by an independent rater according to whether they were primarily reliving, distancing, affect or material other than the primary trauma. The coding system was found to have satisfactory inter-rater reliability. Greatest improvement occurred when the participant processed in a more detached or distant manner, whereas reliving responses were not associated with improvement. Cross-lagged panel correlations suggested that processing in a more detached manner was a consequence of the EMDR procedure rather than a measure that co-varied with improvement. The findings underscored a difference in the processes that underlie EMDR and traditional CBT.
The major question left unanswered from this second study was what causes this distancing process? Competing views were that it was facilitated by eye movement; alternatively, the therapist's instructions to participants might have precipitated this distancing phenomenon. The third study tested these ideas by randomly assigning 48 participants to either an eye movement or a no eye movement condition under two types of therapist instructions (reliving or distancing). Participants recalled personal distressing memories, and measures of distress and vividness were taken after treatment and at follow up. Only the eye movements made a significant difference to people's level of distress.
This conclusion appeared at odds with some of the previous literature that had tested the effects of eye movement on levels of distress. A meta-analysis of some of this research had suggested that there was no significant advantage of including eye movement in EMDR treatment unless the person had been diagnosed with PTSD. However, a close examination of this meta-analysis indicated some major methodological flaws in the computation; therefore, this was recalculated. The conclusion from this fourth study was consistent with study three in that EMDR with eye movement was found to lead to significantly greater improvement that EMDR without eye movement.
The results of these four studies were then discussed in terms of their implications for the theoretical models presented in Chapter 1. Aspects of learning theory that might account for EMDR efficiency were discussed as well as the failure of this model to account for treatment gains following EMDR. Information processing models were seen to better account for some of the phenomena observed in EMDR and for the findings from the four studies. Some suggestions of how eye movements might facilitate improved information processing were presented.
Finally, the relative merits of EMDR and CBT treatments were discussed and suggestions made for when to combine approaches. The conclusions highlight the point that EMDR appears to be the most promising treatment for PTSD.

Format: Journal
Abstract:
This study aimed to investigate the psychophysiological correlates and the effectiveness of different dual-attention tasks used during eye movement desensitization and reprocessing (EMDR). Sixty-two non-clinical participants with negative autobiographical memories received a single session of EMDR without eye movements, or EMDR that included eye movements of either varied or fixed rate of speed. Subjective units of distress and vividness of the memory were recorded at pre-treatment, post-treatment, and 1 week follow-up. EMDR-with eye movements led to greater reduction in distress than EMDR-without eye movements. Heart rate decreased significantly when eye movements began; skin conductance decreased during eye movement sets; heart rate variability and respiration rate increased significantly as eye movements continued; and orienting responses were more frequent in the eye movement than no-eye movement condition at the start of exposure. Findings indicate that the eye movement component in EMDR is beneficial, and is coupled with distinct psychophysiological changes that may aid in processing negative memories.

Abstract:
Since its introduction, Eye Movement Desensitization and Reprocessing (EMDR) (Shapiro, 1989) has received the attention of many mental health professionals. There has been much critical debate on the subject of EMDR. Most of the clinical discussion has centered on the role of EMDR in the treatment of Posttraumatic Stress Disorder (PTSD).
While the EMDR procedure has been compared to Mesmerism (McNally, 1999), declared as pseudoscience (Herbert, Lilienfeld, Lohr, Montgomery, O’Donohue, Rosen, and Tolin, 2000), or regarded as a highly marketed placebo (Lilienfield, 1996), most studies support the efficacy of EMDR in treating PTSD (Ironson, Freund, Strauss, and Williams, 2002; Lee, Gavriel, Drummond, Richards, and Greenwald, 2002; Marcus, Marquis, and Sakai, 1997; Rothbaum, 1997; Van Etten and Taylor, 1998; Wilson, Becker, and Tinker, 1997). There has been some evidence for accompanying physiological changes in PTSD subjects treated with EMDR with patterns of cortex functioning, (Levin, Lazrove, and van der Kolk, 1999; Nicosia, 1994) event-related potential changes (Lamprecht, Kohnke, Sack, Matzke and Munte, 2004), as well as positive effects on the level of the stress hormone cortisol (Haber, Kellner and Yehuda, 2002).

Language: English
Format: Conference
Abstract:
Some of the earliest applications of EMDR were with military veterans (Shapiro 1995, Shapiro & Forrest 1997).
EMDR is now widely used to treat UK military personnel suffering from combat related PTSD. This presentation
will consider extending the use of EMDR as an early intervention during frontline operations. Research suggests
the importance of early detection in PTSD (Lee et al 2005) and the benefits of early intervention (North 2001).
Current practice is that UK personnel who are having significant difficulties in functioning after exposure to
trauma are sent back to the UK for treatment after a brief period of watchful waiting. This is can be detrimental,
both to the unit and individual (Shepard 2000, Solomon et al 2005). EMDR offers a potential solution to this
problem. A case study will be presented of a soldier who was suffering significant post trauma symptoms whilst
serving in Afghanistan. Through the successful use of EMDR in theatre just 2 weeks after the trigger event, he
was able to resume his normal duties and hence avoid the negative effects of being returned to the UK for
treatment. The use of EMDR as a frontline treatment has far reaching implications but currently there is little
evidence for its use as an early intervention with military personnel (Russell 2006). Future research to evaluate
this novel application of EMDR is planned. This presentation will introduce participants to the challenges of
providing psychological treatment during military operations and the potential value of EMDR in this setting.

Abstract:
Het leidt geen enkele twijfel dat EMDR een effectieve behandelvorm is. EMDR is opgenomen in de guidelines van de International Society for Traumatic Stress Studies (ISTSS) waarbij zowel EMDR als Imaginaire Exposure (IE) als ‘treatment of choice’ bij de behandeling van PTSS gelden. Ook in de Nederlandse GGZ-richtlijnen (Trimbos Instituut, 2003) worden EMDR en imaginaire exposure (IE) genoemd als superieure behandelvormen voor PTSS. Rechtstreekse vergelijking van CGt en EMDR leverde echter wisselende resultaten op. Over het geheel genomen kan worden gesteld dat wat betreft effectiviteit er geen duidelijk verschil is vastgesteld tussen CGt en EMDR.
Dit is opvallend, omdat de procedures en de veronderstelde werkingsmechanismen bij IE en EMDR duidelijk verschillen. Bij IE wordt reliving essentieel geacht en bij EMDR distancing. Hier is echter nog nauwelijks expliciet onderzoek naar gedaan; het meeste onderzoek heeft zich tot nu toe gericht op de effectiviteit van EMDR en op de rol van de BLS. In deze presentatie zullen drie eigen experimenten worden besproken die worden uitgevoerd met masterstudenten van de Universiteit Utrecht naar het effect van reliving versus distancing. Het onderzoek bouwt voort op het werk van de Chris Lee en zijn collega’s. (Lee et al 2006)
In het onderzoek worden 3 experimenten uitgevoerd, waarbij de variabele distancing en reliving worden gevarieerd. Verondersteld wordt (vanuit de EMDR visie) dat responses tijdens de desensitisatiefase, die getuigen van distancing leiden tot meer verbetering dan responses die getuigen van reliving. Een tweede onderzoeksvraag die wij beogen te beantwoorden is of dit verschil groter is voor narigheid uit het domein “zelfwaardering” dan voor narigheid uit het “domein controle en machteloosheid”. Een derde onderzoeksvraag betreft de vraag of een verhoogde parasympatische (arousal onderdrukkende) activiteit (een reeds aangetoond effect van BLS) samengaat met veranderingen in SUD-niveau en levendigheid van de herinneringen.
De workshop is bedoeld voor therapeuten die geïnteresseerd zijn in de achtergronden van EMDR. Op zo eenvoudig mogelijke wijze zal een overzicht worden gegeven van de “state of the art” met betrekking tot de veronderstelde werkingsmechanismen. Dit zal worden geïllustreerd met bovengenoemd onderzoek en videomateriaal. Aan het eind van de workshop zal de therapeut zijn cliënten en collega’s iets meer kunnen zeggen dan “ dat EMDR de verwerking stimuleert door de linker en de hersenhelften beter te laten samenwerken, waardoor gevoel en verstand beter met elkaar verbonden raken.”
There is no doubt that EMDR is an effective form of treatment. EMDR is included in the guidelines of the International Society for Traumatic Stress Studies (ISTSS) where both EMDR and imaginal exposure (IE) as treatment of choice in the treatment of PTSD are. Also in the Dutch mental health care directives (Trimbos Institute, 2003) are EMDR and imaginal exposure (IE) identified as superior forms of treatment for PTSD. Direct comparison of CBT and EMDR yielded mixed results, however. Overall it can be stated that in terms of effectiveness there is no clear difference observed between CBT and EMDR.
This is striking because the procedures and mechanisms assumed by IE and EMDR markedly different. When IE is reliving considered essential to EMDR and distancing. There is still little research has been done explicitly, most research has hitherto focused on the effectiveness of EMDR and the role of the BLS. This presentation will discuss three own experiments conducted with master students of the University of Utrecht to the effect of relieving versus distance. The research builds on the work of Chris Lee and his colleagues. (Lee et al 2006)
In the study, three experiments, with variable distancing and reliving be varied. It is assumed (from the EMDR vision) that responses during desensitisatiefase, evidence of distancing lead to more improvement than responses that show reliving. A second research question we seek to answer is whether this difference is in trouble from the domain "esteem" than for trouble from the "domain control and powerlessness". A third research question concerns whether an increased parasympathetic (arousal suppressive) activity (an effect already demonstrated BLS) is associated with changes in SUD level and vividness of the memories.
The workshop is designed for therapists interested in the backgrounds of EMDR. In the simplest possible manner, an overview of the state of the art "regarding the supposed mechanisms of action. This will be illustrated with the above study and video material. At the end of the workshop, the therapist will have clients and colleagues can say little more than "that EMDR stimulates the processing by the left and the brain work better together, making sense and intellect more interrelated."

Abstract:
Objective: Previous reviews have been critical of eye movement desensitisation and reprocessing (EMDR). It has been claimed that EMDR lacked empirical support, contributed nothing new to existing treatments, that the eye movements were irrelevant and that its mechanism of action was unknown [1]. The specific claims were addressed in the light of recent studies.

Abstract:
Controlled studies of treatments effective with victims of natural disasters are almost nonexistent. This is a small study conducted under difficult conditions to test the effectiveness of Eye Movement Desensitization and Reprocessing (EMDR) in treating trauma related reactions following Hurricane Andrew. The results were positive in that EMDR produced significant improvement over wait list controls in perceived posttraumatic avoidance behaviors and thoughts as measured by changes in the Impact of Event Scale and significant improvement in subjective aversive reactions to representative experiences of the hurricane. These results suggest and support other studies that EMDR can be an effective therapeutic intervention for trauma reactions. [Author Abstract]

This paper reviews the present state of knowledge about the efficacy of eye movement desensitisation and reprocessing (EMDR) as a treatment for traumatic memories, and draws on information-processing theory to identify basic problems with much of the research on this procedure. The general failure of this research to take into account the complexity and hypothesised theoretical underpinnings of EMDR is discussed, and suggestions are made for future research. Although EMDR has shown some promise as an effective intervention for PTSD, well controlled comparative outcome studies are required to establish its efficacy before investigation of its active therapeutic components should be undertaken.

are effective and whether they influence the effectiveness of therapist instructions.

It was hypothesized that distancing instructions, compared to reliving instructions, would cause a
stronger decrease in subjective distress and nowness of the event. Furthermore it was expected that
the vividness of the event would decrease during the session, regardless of the instructions. In every
subject the sympathetic and parasympathetic activity of the nervous system is measured. It was
supposed that the sympathetic activity would have a stronger decrease in the distancing condition
compared to the reliving condition. A stronger increase was expected for the parasympathetic activity
in the distancing condition, in comparison with the reliving condition. Moreover, at the beginning of the
session the sympathetic activity would be higher in the reliving condition than in the distancing
condition, in contrast to the parasympathetic activity. The research has been conducted by and among

Abstract:
Dit onderzoek is een replicatie van de studie van Lee, Taylor en Drummond (2006) waarin de werkingsmechanismen beschrijft tijdens een desensibilisatie Eye Movement and Reprocessing (EMDR) behandeling. Deze studie onderzocht of er een relatie is tussen verbetering van de symptomen en de manier waarop de cliënt ziet de traumatische gebeurtenis, is dit vanuit een oogpunt van vrijstaande (afstand) of wanneer het trauma opnieuw wordt ervaren (herbeleving). De reacties van de 30 klanten tijdens een EMDR sessie, worden ingedeeld in vier categorieën volgens de classificatie van Lee et al.. (2006) (distantiëring, herbeleven, beïnvloeden en verbonden). Toegevoegd in dit onderzoek is de categorie onbeslist. De resultaten laten zien is er geen verschil in de antwoorden die tijdens een EMDR sessie en de vermindering van PTSS-symptomen (gemeten met de Nederlandse versie van de Impact of Event Scale) en van het verdriet (gemeten met de subjectieve Eenheden van Disturbance Scale). Alle reacties zijn gerelateerd aan een verbetering, ongeacht de categorie. Deze resultaten zijn niet in overeenstemming met de bevindingen van Lee et al.. (2006) die aantonen dat afstand-reacties zijn geassocieerd met een grotere vermindering van de symptomen dan herbeleven-reacties. Naast Lee et al.. (2006), de huidige studie is gebleken dat zowel de aard van het trauma (opzettelijk of niet opzettelijk) alsmede de negatieve cognitie van een cliënt (onmacht of eigenwaarde) niet zijn geassocieerd met een verbetering van de symptomen tijdens de EMDR behandeling. Toekomstig onderzoek kan bijdragen aan kennis over andere factoren die geassocieerd kan worden met de effectiviteit van EMDR.
This research is a replication of the study of Lee, Taylor and Drummond (2006) which describes the working mechanisms during an Eye Movement Desensitization and Reprocessing (EMDR) treatment. This study tested whether there is a relation between improvement in symptoms and the way the client sees the traumatic event; is this from a detached point of view (distancing) or when the trauma is re-experienced (reliving).The responses of 30 clients during an EMDR session, are classified into four categories according to the classification of Lee et al. (2006) (distancing, reliving, affect and associated). Added in this study is the category undecided. The results show there is no difference in the responses given during an EMDR session and the reduction of PTSD-symptoms (measured with the Dutch version of the Impact of Event Scale) and of the distress (measured with the Subjective Units of Disturbance Scale). All the responses are related to an improvement, regardless of the category. These results are not in line with the findings of Lee et al. (2006) that show distancing-reactions are associated with a greater reduction in symptoms than reliving-reactions. In addition to Lee et al. (2006), the current study found that both the nature of the trauma (intentional or not intentional) as well as the negative cognition of a client (powerlessness or self-esteem) are not associated with an improvement in symptoms during EMDR treatment. Future research may contribute to knowledge about other factors that may be associated with the effectiveness of EMDR.

Abstract:
This study examined possible therapeutic mechanism of eye movements in Eye
Movement Desensitization and Reprocessing (EMDR). Several studies have reported
that bilateral eye movements during imagery could decrease vividness and
emotionality of recollections. This study proposed a hypothesis, that was, the
reduction of recall was due to the interference of spontaneous eye movements
including conjugate lateral eye movements (CLEMs). 110 undergraduate students
(47 men, 63 women) recalled two positive and two negative memories (the CLEMs of
these memories were recorded by a digital camera at the same time) and rated their
vividness and emotionality of the recollections. Next, participants recalled the
memories while they were engaging in five between-group conditions (bilateral eye
movements, left gaze, right gaze, central gaze, and mere imagery condition). Then
participants recalled the event again and rated its vividness and emotionality. The
results showed that the bilateral eye movements made autobiographical memories less
vivid and less emotive, while mere image increased the vividness and emotionality of
autobiographical memories (ps < .05). Importantly, there was only one significant
Valence × Time interaction effect (p < .05) in the left gaze condition. It showed that
right hemisphere involved more negative emotions than positive, whereas left
hemisphere involved no differences between negative and positive emotions. With
regard to CLEMs, there were no different lateral eye movements between negative
and positive memories. The study supported the idea that bilateral eye movements
during imagery could decrease vividness and emotionality of recollections, and that
interfering spontaneous eye movements changed vividness and emotionality of
autobiographical memories. The role of eye movements in the EMDR was discussed.

Abstract:
Research background: It was noted that when people recalled an
emotional event, there is a spontaneous eye movements during retrieval
of memory, known as conjugate lateral eye movements (CLEM). Eye
movements during mental imagery are not epiphenomenal but assist the
process of image generation (Hebb, 1968; Brandt & Stark, 1997). If
restricted to a fixed point, then the image of recall is impaired (Laeng &
Teodorescu 2002). These findings might shed light on why bilateral eye
movements during imagery could decrease vividness and emotionality of
recollections.
Objectives: Based on the above findings, this study examined possible
therapeutic mechanism of eye movements in Eye Movement
Desensitization and Reprocessing (EMDR; Shapiro, 1989, 1995, 2001),
of which eye movement was a crucial treatment component. Specifically,
the hypothesis that interfering CLEM via introducing bilateral eye
movements or a fixed position could reduce vividness and emotionality of
autobiographical memories was examined in the present study. Further,
whether there are different CLEMs (more rightward in positive and more
leftward in negative) during retrieval of positive and negative memories
was also investigated.
Method: Seventeen healthy volunteers recalled two positive and two
negative memories and rated their vividness and emotionality of the
recollections. Next, memories were recalled whilst the participant was
performing either bilateral eye movements (interference of CLEM) or
mere image condition (non-interference of CLEM). Then participants
were asked to recall the event again and to rate its vividness and
emotionality. Vividness and emotionality ratings were analyzed using a 2
(EM condition: bilateral eye movement vs. mere image) × 2 (valence of
memory: positive vs. negative) × 2 (time: before vs. after the intervention)
repeated measures analysis of variance (ANOVA). During the first and
last recall of each memory CLEM were recorded by a digital camera. To
examine the effect of CLEM during recollections on emotionality and
vividness of autobiographical memories, eye movements in each recall
were counted into percentage time of eye gaze in three regions (leftward,
middle, rightward), instead of counting the first lateral eye movement as
used by the traditional method.
Results: Compared to mere image condition, recollections after bilateral
eye movements made subsequent recollections less vivid and less
emotive, while the opposite was true for mere image condition.
Regarding vividness, the 2 × 2 × 2 ANOVA showed that there was a
significant condition × time interaction. None of the other interactions or
main effects reached significance. Simple main effect indicated that the
change in vividness was significant in the mere image condition, but not
in the eye movement condition. As to emotionality, the three way
ANOVA showed that there was also a significant condition × time
interaction. None of the other interactions or main effects reached
significance. Simple main effect indicated that the change in emotionality
was significant in the mere image condition, and in eye movement
condition. Concerning percentage of gaze direction (left, right) in positive
and negative memories, pair t test showed that there was a significant
right gaze difference between positive and negative memories, and
approached significant left gaze difference between positive and negative
memories. With regard to CLEM, negative memories showed less right
gazes and more left gazes than positive memories.
Conclusion:The bilateral eye movements made autobiographical
memories less vivid and less emotive than mere image condition, while
mere image increased the vividness and emotionality of autobiographical
memories. Further, there is different CLEM for negative and positive
memories. While the hypothesis that interference of CLEM reduced the
vividness and emotionality of autobiographical memories was confirmed,
the role of eye movement in the EMDR was discussed and future research
possibilities are proposed.

Abstract:
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.

Abstract:
O objetivo do trabalho é apresentar uma revisão sobre o efeito dos movimentos oculares durante a exposição a memórias traumáticas a partir do paradigma da Teoria da Memória de Trabalho. Shapiro (2001) afirmou que a compreensão do mecanismo de ação do EMDR por meio da análise do efeito de seus componentes pode permitir cada vez mais seu aprimoramento. A meta-análise de Lee e Cuijpers (2012) mostra a importância dos movimentos oculares para a diminuição da vivacidade e das emoções negativas associadas às memórias traumáticas. Segundo a Teoria da Memória de Trabalho, a realização de movimentos oculares durante a manutenção de memórias traumáticas causaria a taxação da memória de trabalho, tornando as imagens menos vívidas e emocionais (ex. Gunter e Bodner 2008; van Den Hout et al. 2011). Quanto maior a taxação da memória de trabalho, desde que não cause prejuízo da manutenção da memória na mente, maior é a redução da vivacidade e intensidade (Gunter e Bodner 2008; van Den Hout et al. 2011, Engelhard et al. 2010, 2011). Portanto, a intensidade dos movimentos oculares parece ser importante para o efeito terapêutico. Smeets et al. (2012), ao investigarem o decurso temporal desses efeitos, verificaram que os movimentos oculares interferem primeiro com a vivacidade da memória. A redução da emocionalidade ocorre posteriormente. Por sua vez, Engelhard et al. (2010, 2011) têm mostrado que os movimentos oculares também são benéficos em relação a imagens negativas de eventos futuros, indicando um efeito terapêutico do EMDR sobre psicopatologias em que essas imagens estão presentes.Assim, em consonância com a afirmação de Shapiro (2001), estudos mostram a importância de se correlacionar a prática clínica com as investigações científicas sobre componentes do EMDR (ver Engelhard 2012). Além de favorecer a compreensão, a aplicação e a revisão dos protocolos, a correlação possui implicações clínicas importantes.
The objective is to present a review on the effect of eye movements during exposure to traumatic memories from the paradigm of the Theory of Working Memory. Shapiro (2001) stated that understanding the mechanism of action of EMDR through the analysis of the effect of its components can increasingly allow their improvement. A meta-analysis of Lee and Cuijpers (2012) shows the importance of eye movements to decrease the vividness and negative emotions associated with traumatic memories. According to the Theory of Working Memory, conducting eye movements during maintenance of traumatic memories cause the tax working memory, making the images less vivid and emotional (eg Gunter and Bodner 2008; van den Hout et al. 2011) . The higher taxation of working memory, since it does not cause prejudice to the maintenance of memory in mind, the greater the reduction in vividness and intensity (Gunter and Bodner 2008; van den Hout et al., 2011, Engelhard et al. 2010, 2011 ). Therefore, the intensity of eye movements seem to be important to the therapeutic effect. Smeets et al. (2012) investigated the time course of these effects and found that eye movements interfere first with the vividness of memory. The reduction in emotionality occurs later. In turn, Engelhard et al. (2010, 2011) have shown that eye movements are also beneficial in relation to negative images of future events, indicating a therapeutic effect of EMDR on psychopathology in which these images are presentes.Assim, in line with the statement Shapiro (2001) studies show the importance of correlating clinical practice with scientific research on components of EMDR (see Engelhard 2012). Besides promote understanding, implementation and review of protocols, the correlation has important clinical implications.

It concluded that the evidence was inadequate to determine the efficacy of eye movement desensitization and reprocessing (EMDR) in the treatment of PTSD. However, a critical examination of the basis for this conclusion reveals errors in three areas. First, the findings of key studies that reported positive outcomes for EMDR were misrepresented; second, a number of positive studies were excluded without apparent justification; and, finally, the IOM report failed to consider additional readily available studies that also reported benefits for EMDR. These factors appear to explain why the conclusions of the IOM report are at odds with the numerous meta-analyses and practice guidelines of PTSD treatments issued by other scientific committees worldwide.

Abstract:
Objectives: Eye movement desensitization and reprocessing(EMDR) is a novel, time-limited psychotherapy originally developed for treatment of psychological trauma. The effectiveness of this therapy has been validated only for posttraumatic stress disorder; however, EMDR is often applied to other psychiatric illnesses, including other anxiety disorders and depression. This pilot study tested the efficacy of EMDR added to the routine treatment for individuals with acute stage schizophrenia. Methods: This study was conducted in the acute psychiatric care unit of a university-affiliated training hospital. Inpatients diagnosed with schizophrenia were randomly assigned to either three sessions of EMDR, three sessions of progressive muscle relaxation(PMR) therapy, or only treatment as usual(TAU). All the participants received concurrent typical treatments(TAU), including psychotropic medication, individual supportive psychotherapy and group activities in the psychiatric ward. The Positive and Negative Syndrome Scale(PANSS), the Hamilton Depression Rating Scale and the Hamilton Anxiety Rating Scale were administered by a clinical psychologist who was blinded to the patients' group assignment. Results: Forty-five patients enrolled and forty patients(89%) completed the post-treatment evaluation. There were no between-group differences in the withdrawal rates of patients during the treatment or at the three-month follow-up session. All three groups improved significantly across each of the symptomatic domains including schizophrenia, anxiety, and depressive symptoms. However, a repeated measures ANOVA revealed no significant differences among the groups over time. Effect size for change in total PANSS scores was also similar across treatment conditions, but effect size for negative symptoms was large for EMDR(0.60 for EMDR, 0.39 for PMR and 0.21 for TAU only). Conclusion: These findings supported the use of EMDR in treating the acute stage of schizophrenia but the results failed to confirm the effectiveness of the treatment over the two control conditions in three sessions. Further studies with longer courses of treatment, more focused target dimensions of treatment, and a sample of outpatients are necessary.

Abstract:
We investigated the relationship between plasma levels of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) and responses to eye movement desensitisation and reprocessing (EMDR) in complex PTSD. Before and after EMDR, plasma levels of neurotrophic factors and scores in the indices of self-questionnaires were obtained for 8 men with complex PTSD. Baseline plasma levels of BDNF and NGF of responders and of non-responders were compared. The plasma BDNF levels of responders were higher than those of non-responders. However, plasma NGF levels did not differ in two groups. Plasma BDNF level might contribute to the therapeutic response to EMDR in trauma-related psychiatric disorders, such as complex PTSD. [Text]

Abstract:
EMDRIA has submitted comments critical of the Institute of Medicine (IOM) report commissioned by the Department of Veterans Affairs to assess the scientific evidence on treatment modalities for PTSD. The 2007 report concluded that “the evidence is inadequate to determine the efficacy of EMDR in the treatment of PTSD.” The response, authored by Dr. Christopher Lee, Research Chair, and reviewed by the Research Committee, details serious omissions and misinterpretations of the scientific literature that would have effected the conclusions about EMDR in the report. Dr. Lee also prepared a PowerPoint presentation for EMDRIA members to use.

eople who were exposed to chronic interpersonal traumas in their early life consistently demonstrate complex psychological disturbances and many of them meet the criteria for proposed diagnosis of complex posttraumatic stress disorder (complex PTSD). The authors report a case of the successful sequential integrative treatment mainly composed of eye movement desensitization and reprocessing (EMDR) in a complex PTSD patient. The patient did not respond to the previous treatment with psychotropic medications and supportive psychotherapy.
Twelve sessions of EMDR and three sessions of supportive psychotherapy were done for the patient. Psychological assessments were performed before starting the treatment and a week after completing the treatment. After the treatment, the patient improved on all the psychological scales and behavior measures. The case suggests that the integrative treatment composed of EMDR may be [unfinished abstract as found in the Conference Program]

Abstract:
The effectiveness of Stress Inoculation Training with Prolonged Exposure (SITPE) was compared to Eye Movement Desensitization and Reprocessing (EMDR). 24 participants who had a diagnosis of PTSD were randomly assigned to one of the treatment conditions. Participants were also their own wait-list control. Outcome measures included self-report and observer-rated measures of PTSD, and self-report measures of depression. On global PTSD measures, there were no significant differences between the treatments at the end of therapy. However on the subscale measures of the degree of intrusion symptoms, EMDR did significantly better than SITPE. At follow-up EMDR was found to lead to greater gains, on all measures.
