Mediated moderation in combined cognitive behavioral therapy versus component treatments for generalized anxiety disorder.

OBJECTIVE: This study examined (a) duration of generalized anxiety disorder (GAD) as a moderator of cognitive behavioral therapy (CBT) versus its components (cognitive therapy and self-control desensitization) and (b) increases in dynamic flexibility of anxious symptoms during the course of psychotherapy as a mediator of this moderation. Degree of dynamic flexibility in daily symptoms was quantified as the inverse of spectral power due to daily to intradaily oscillations in four-times-daily diary data (Fisher, Newman, & Molenaar, 2011). METHOD: This was a secondary analysis of the data of Borkovec, Newman, Pincus, and Lytle (2002). Seventy-six participants with a principle diagnosis of GAD were assigned randomly to combined CBT (n = 24), cognitive therapy (n = 25), or self-control desensitization (n = 27). RESULTS: Duration of GAD moderated outcome such that those with longer duration showed greater reliable change from component treatments than they showed from CBT, whereas those with shorter duration fared better in response to CBT. Decreasing predictability in daily and intradaily oscillations of anxiety symptoms during therapy reflected less rigidity and more flexible responding. Increases in flexibility over the course of therapy fully mediated the moderating effect of GAD duration on condition, indicating a mediated moderation process. CONCLUSIONS: Individuals with longer duration of GAD may respond better to more focused treatments, whereas those with shorter duration of GAD may respond better to a treatment that offers more coping strategies. Importantly, the mechanism by which this moderation occurs appears to be the establishment of flexible responding during treatment.

Time-course of eye movement-related decrease in vividness and emotionality of unpleasant autobiographical memories.

The time-course of changes in vividness and emotionality of unpleasant autobiographical memories associated with making eye movements (eye movement desensitisation and reprocessing, EMDR) was investigated. Participants retrieved unpleasant autobiographical memories and rated their vividness and emotionality prior to and following 96 seconds of making eye movements (EM) or keeping eyes stationary (ES); at 2, 4, 6, and 10 seconds into the intervention; then followed by regular larger intervals throughout the 96-second intervention. Results revealed a significant drop compared to the ES group in emotionality after 74 seconds compared to a significant drop in vividness at only 2 seconds into the intervention. These results support that emotionality becomes reduced only after vividness has dropped. The results are discussed in light of working memory theory and visual imagery theory, following which the regular refreshment of the visual memory needed to maintain it in working memory is interfered with by eye movements that also tax working memory, which affects vividness first.

[Comparison of the effectiveness of cognitive restructuring and systematic desensitization in reducing high-stakes test anxiety]. / Yüksek Riskli Sinav Kaygisinin Azaltilmasinda Sistematik Duyarsizlastirma ile Bilissel Yeniden Yapilandirmanin Etkililiginin Karsilastirilmasi.

OBJECTIVE: This study aimed to compare the effectiveness of systematic desensitization (behavioral therapy and cognitive restructuring (cognitive therapy) in reducing high-stakes test anxiety. We hypothesized that cognitive restructuring would be superior to systematic desensitization in reducing the severity of the cognitive symptoms of anxiety, whereas systematic desensitization would be superior to cognitive restructuring in reducing the severity of the physiological symptoms of anxiety. MATERIALS AND METHOD: The study included 50 (36 female and 14 male) high school graduates and high school seniors aged 16-22 years (mean:18.3 years) that experienced test anxiety while taking their university entrance exam. Participants were randomly assigned to the behavior therapy or cognitive therapy groups. Participants in both groups received 9 sessions of structured group therapy with the same therapist. Each participant's level of anxiety and depression, psychiatric symptoms, and dysfunctional thoughts were measured throughout the therapy process. RESULTS: Statistical analysis showed that there was a significant decrease in the score of each outcome measure employed in both groups. There weren't any significant differences in terms of the alleviation of the cognitive symptoms of anxiety, as measured with the Dysfunctional Attitudes Scale, or physiological symptoms, as assessed with the Beck Anxiety Inventory between the 2 groups. The 2 therapy methods resulted in statistically significant reductions in the level of test anxiety, as well as state anxiety, trait anxiety, self-reported depression, and general symptom levels. CONCLUSION: The behavioral and cognitive therapies were equally effective in reducing the severity of the cognitive and physiological components of test anxiety.

Changes in PTSD patients' narratives during prolonged exposure therapy: a replication and extension.

Following E. B. Foa, C. Molnar, and L. Cashman (1995), narrative changes from the first to the last exposure session were compared for improved and nonimproved PTSD patients on fragmentation, organization, internal, and external events. Improved (n = 8) and nonimproved (n = 12) patients did not differ regarding changes in fragmentation or organized thoughts. However, improved patients showed a greater decrease in disorganized thoughts during treatment. Furthermore, all patients, independent of improvement, showed significant changes in the same direction; a decrease in disorganized thoughts and external events and an increase in internal events. Although previous results were partly replicated, it is concluded that narrative changes may be due to exposure treatment itself rather than to changes in memory representation.

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.

Treatment of specific phobias with Eye Movement Desensitization and Reprocessing (EMDR): protocol, empirical status, and conceptual issues.

This paper considers the current empirical status of Eye Movement Desensitization and Reprocessing (EMDR) as a treatment method for specific phobias, along with some conceptual and practical issues in relation to its use. Both uncontrolled and controlled studies on the application of EMDR with specific phobias demonstrate that EMDR can produce significant improvements within a limited number of sessions. With regard to the treatment of childhood spider phobia, EMDR has been found to be more effective than a placebo control condition, but less effective than exposure in vivo. The empirical support for EMDR with specific phobias is still meagre, therefore, one should remain cautious. However, given that there is insufficient research to validate any method for complex or trauma related phobias, that EMDR is a time-limited procedure, and that it can be used in cases for which an exposure in vivo approach is difficult to administer, the application of EMDR with specific phobias merits further clinical and research attention.

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.

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.

A single session, group study of exposure and Eye Movement Desensitization and Reprocessing in treating Posttraumatic Stress Disorder among Vietnam War veterans: preliminary data.

This report summarizes data gathered thus far from an ongoing study. Two groups (total N = 12) of Vietnam War veterans diagnosed with Posttraumatic Stress Disorder (PTSD) received a single session of exposure or Eye Movement Desensitization and Reprocessing (EMDR) focusing on the veterans' most distressing war experience. Group assignment was random, treatment providers were blind to assessment data, and the pre- and posttreatment assessor was blind to treatment assignment. Both groups showed improvement on the Impact of Event Scale. EMDR treatment resulted in greater positive changes in within-session Subjective Units of Discomfort levels and on self-monitored severity of intrusive recollection. A trend toward decreased heart rate reactivity was observed in both groups. Results must be considered carefully due to the small number of subjects used in the study.

The relative efficacy and treatment distress of EMDR and a cognitive-behavior trauma treatment protocol in the amelioration of posttraumatic stress disorder.

The growing body of research into treatment efficacy with Posttraumatic Stress Disorder (PTSD) has, by-and-large, been limited to evaluating treatment components or comparing a specific treatment against wait-list controls. This has led to two forms of treatment, Eye Movement Desensitization and Reprocessing (EMDR) and Cognitive-Behavior Therapy (CBT), vying for supremacy without a controlled study actually comparing them. The present research compared EMDR and a CBT variant (Trauma Treatment Protocol; TTP) in the treatment of PTSD, via a controlled clinical study using therapists trained in both procedures. It was found that TTP was both statistically and clinically more effective in reducing pathology related to PTSD and that this superiority was maintained and, in fact, became more evident by 3-month follow-up. These results are discussed in terms of past research. Directions for future research are suggested.

Treatment fidelity and research on Eye Movement Desensitization and Reprocessing (EMDR).

Eye Movement Desensitization and Reprocessing was introduced by Frances Shapiro (1989) as a treatment for posttraumatic stress disorder. When controlled studies failed to support the extraordinarily positive findings and claims made by Shapiro, proponents of EMDR raised the issue of treatment fidelity and criticized researchers for being inadequately trained. This paper considers the issues raised by EMDR proponents. It is concluded that treatment fidelity has been used as a specious, distracting issue that permits the continued promotion of EMDR in the face of negative empirical findings. Clinical psychologists are urged to remember the basic tenets of science when evaluating extraordinary claims made for novel techniques.

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.

Traumatic memories, eye movements, phobia, and panic: a critical note on the proliferation of EMDR.

In the past years, Eye Movement Desensitization and Reprocessing (EMDR) has become increasingly popular as a treatment method for Posttraumatic Stress Disorder (PTSD). The current article critically evaluates three recurring assumptions in EMDR literature: (a) the notion that traumatic memories are fixed and stable and that flashbacks are accurate reproductions of the traumatic incident; (b) the idea that eye movements, or other lateralized rhythmic behaviors have an inhibitory effect on emotional memories; and (c) the assumption that EMDR is not only effective in treating PTSD, but can also be successfully applied to other psychopathological conditions. There is little support for any of these three assumptions. Meanwhile, the expansion of the theoretical underpinnings of EMDR in the absence of a sound empirical basis casts doubts on the massive proliferation of this treatment method.

EMDR and Mesmerism: a comparative historical analysis.

Eye movement desensitization and reprocessing (EMDR) is among the fastest growing interventions in the annals of psychotherapy. Although many psychologists have commented on its presumably unusual origins and dissemination, history reveals its many parallels with Mesmerism, a previous therapy that spread rapidly throughout 18th century Europe and America. The purpose of this article is to document the many striking similarities between the history of Mesmerism and the history of EMDR.

Cognitive and behavioural treatment of hypochondriasis.

BACKGROUND: This study investigates the feasibility and effectiveness of time-limited treatment protocols based upon cognitive and behavioural interventions. METHOD: Seventeen patients with DSM-IV diagnoses of hypochondriasis were offered 12 1-hour sessions of either 'pure' cognitive or 'pure' behavioural (i.e. exposure in vivo and response prevention) treatment. Patients were used as their own controls by observing a 4-week period without interventions before and after treatment. RESULTS: Patients in both treatment conditions improved on specific measures of hypochondriasis (Kellner's Illness Attitude Scales) and depression. These changes took place during the active treatment period, whereas in the control periods scores remained unchanged. Furthermore, no differential treatment effectiveness could be demonstrated. CONCLUSIONS: Cognitive and behavioural interventions seem to be active ingredients in the treatment of hypochondriasis, although the contribution of nonspecific factors (e.g. patient motivation, therapist attitudes, and the therapeutic relationship) requires further study.

CARL: a LabVIEW 3 computer program for conducting exposure therapy for the treatment of dental injection fear.

This paper describes CARL (Computer Assisted Relaxation Learning), a computerized, exposure-based therapy program for the treatment of dental injection fear. The CARL program operates primarily in two different modes; in vitro, which presents a video-taped exposure hierarchy, and in vivo, which presents scripts for a dentist or hygienist to use while working with a subject. Two additional modes are used to train subjects to use the program and to administer behavioral assessment tests. The program contains five different modules, which function to register a subject, train subjects to use physical and cognitive relaxation techniques, deliver an exposure hierarchy, question subjects about the helpfulness of each of the therapy components, and test for memory effects of anxiolytic medication. Nine subjects have completed the CARL therapy program and 1-yr follow-up as participants in a placebo-controlled clinical trial examining the effects of alprazolam on exposure therapy for dental injection phobia. All nine subjects were able to receive two dental injections, and all reduced their general fear of dental injections. Initial results therefore indicate that the CARL program successfully reduces dental injection fear.

A controlled study of eye movement desensitization and reprocessing in the treatment of posttraumatic stress disordered sexual assault victims.

Eye movement desensitization and reprocessing (EMDR) is a new method developed to treat posttraumatic stress disorder (PTSD). This study evaluated the efficacy of EMDR compared to a no-treatment wait-list control in the treatment of PTSD in adult female sexual assault victims. Twenty-one subjects were entered, and 18 completed. Treatment was delivered in four weekly individual sessions. Assessments were conducted pre- and posttreatment and 3 months following treatment termination by an independent assessor kept blind to treatment condition. Measures included standard clinician- and self-administered PTSD and related psychopathology scales. Results indicated that subjects treated with EMDR improved significantly more on PTSD and depression from pre- to posttreatment than control subjects, leading to the conclusion that EMDR was effective in alleviating PTSD in this study.

Does preference for type of treatment matter? A study of exposure in vivo with or without hypnosis in the treatment of panic disorder with agoraphobia.

There is evidence that preference for a given therapy may influence results. Literature also suggests that hypnotizability may be elevated in agoraphobic patients, making hypnosis a potentially powerful method for treatment. Agoraphobic patients (N = 64) were treated with either exposure in vivo or exposure combined with hypnosis in a crossover design. Half of the patients started with the treatment they preferred and the other half received the other treatment first. Although patients' preference clearly shifted in favor of the combined therapy in the course of the study, no effect of preference on outcome was evident. Although hypnotizability clearly correlated to outcome in the combined therapy, no difference in effect between the two therapies was found on behavioral, self-report, and observer measures. No additional effect of hypnosis could be shown and preference was not found to be a powerful mediator of effect.

Behaviour therapy for obsessive-compulsive disorder: a decade of progress.

OBJECTIVE: To review the last decade of behaviour therapy research in obsessive-compulsive disorder (OCD). METHOD: The most salient research was analyzed. RESULTS: Many studies confirmed that exposure and ritual prevention (ERP) effectively reduced compulsive rituals and obsessive thoughts in most patients in all age groups, although a minority of the patients did not complete treatment. Gains persisted to follow-up 2 to 6 years later in several countries. Improvement after ERP generalized to obsessive-compulsive beliefs, mood, work, and social adjustment, and was accompanied by reduction in cerebral blood flow in the right caudate nucleus. Teaching patients how to prevent relapse seems to reduce the risk of recurrence. ERP yields slightly more improvement than does appropriate antidepressant medication and is followed by far less relapse after treatment has stopped, so ERP may be more cost-effective in the long term. Antidepressant medication is a useful adjunct to ERP when OCD is accompanied by comorbid depression. The therapist now tends to teach patients how to carry out self-exposure and self-imposed ritual prevention, rather than to impose ERP on them. Self-help manuals help patients to do this, and computer aids to allow patients to learn how to do ERP at home have been valuable in pilot studies. Cognitive therapy without ERP was as useful as ERP. CONCLUSION: ERP is of lasting value for OCD. Long-term cost-effectiveness comparisons are needed of self-administered ERP versus cognitive therapy and versus medication. Studies are also needed of brief psychological treatment for depression comorbid with OCD.
