MODIFI: protocol for randomised feasibility study of eye-movement desensitisation and reprocessing therapy (EMDR) for functional neurological disorder (FND)

Introduction Functional neurological disorder (FND) refers to an involuntary loss of control over and/or aberrant perception of the body. Common presenting symptoms are functional (non-epileptic) seizures, and functional motor disorder, for example, walking difficulties, weakness or tremor. Greater access to effective treatments would lead to reduced distress and disability; and reduce unnecessary healthcare costs.This study will examine eye-movement desensitisation and reprocessing therapy (EMDR) as a treatment for FND. EMDR is an evidence-based treatment for post-traumatic stress disorder (PTSD), but its use for other conditions is growing. An FND-specific EMDR protocol will be tested, and if the intervention proves feasible with promising clinical outcomes, progression to a substantive study could take place.Methods and analysis Fifty adult patients diagnosed with FND will be recruited. It will be a single-blind randomised controlled trial with two arms: EMDR (plus standard neuropsychiatric care; NPC) and standard NPC. The two groups will be compared at baseline (T0), 3 months (T1), 6 months (T2) and 9 months (T3). Measures of feasibility include safety, recruitment, retention, treatment adherence and acceptability. Clinical outcome measures will assess health-related functioning/quality of life, ratings of FND symptoms and severity, depression, anxiety, PTSD, dissociation, service utilisation and other costs. Improvement and satisfaction ratings will also be assessed. Feasibility outcomes will be summarised using descriptive statistics. Exploratory analyses using (linear/logistic) mixed-effect models will examine the rate of change in the groups’ clinical outcome measures across the four time-points.After the intervention period, a sample of participants, and clinicians, will be invited to attend semistructured interviews. The interviews will be analysed using reflexive thematic analysis.Ethics and dissemination This study has been approved by the NHS West Midlands—Edgbaston Research Ethics Committee. Study findings will be published in open access peer-reviewed journals, presented at conferences, and communicated to participants and other relevant stakeholders.Trial registration NCT05455450 (www.clinicaltrials.gov)

Cost-effectiveness of psychological treatments for post-traumatic stress disorder in adults

BackgroundPost-traumatic stress disorder (PTSD) is a severe and disabling condition that may lead to functional impairment and reduced productivity. Psychological interventions have been shown to be effective in its management. The objective of this study was to assess the cost-effectiveness of a range of interventions for adults with PTSD.MethodsA decision-analytic model was constructed to compare costs and quality-adjusted life-years (QALYs) of 10 interventions and no treatment for adults with PTSD, from the perspective of the National Health Service and personal social services in England. Effectiveness data were derived from a systematic review and network meta-analysis. Other model input parameters were based on published sources, supplemented by expert opinion.ResultsEye movement desensitisation and reprocessing (EMDR) appeared to be the most cost-effective intervention for adults with PTSD (with a probability of 0.34 amongst the 11 evaluated options at a cost-effectiveness threshold of £20,000/QALY), followed by combined somatic/cognitive therapies, self-help with support, psychoeducation, selective serotonin reuptake inhibitors (SSRIs), trauma-focused cognitive behavioural therapy (TF-CBT), self-help without support, non-TF-CBT and combined TF-CBT/SSRIs. Counselling appeared to be less cost-effective than no treatment. TF-CBT had the largest evidence base.ConclusionsA number of interventions appear to be cost-effective for the management of PTSD in adults. EMDR appears to be the most cost-effective amongst them. TF-CBT has the largest evidence base. There remains a need for well-conducted studies that examine the long-term clinical and cost-effectiveness of a range of treatments for adults with PTSD

Psychological treatments for post-traumatic stress disorder in adults: : a network meta-analysis

BACKGROUND: Post-traumatic stress disorder (PTSD) is a potentially chronic and disabling disorder affecting a significant minority of people exposed to trauma. Various psychological treatments have been shown to be effective, but their relative effects are not well established. METHODS: We undertook a systematic review and network meta-analyses of psychological interventions for adults with PTSD. Outcomes included PTSD symptom change scores post-treatment and at 1-4-month follow-up, and remission post-treatment. RESULTS: We included 90 trials, 6560 individuals and 22 interventions. Evidence was of moderate-to-low quality. Eye movement desensitisation and reprocessing (EMDR) [standardised mean difference (SMD) -2.07; 95% credible interval (CrI) -2.70 to -1.44], combined somatic/cognitive therapies (SMD -1.69; 95% CrI -2.66 to -0.73), trauma-focused cognitive behavioural therapy (TF-CBT) (SMD -1.46; 95% CrI -1.87 to -1.05) and self-help with support (SMD -1.46; 95% CrI -2.33 to -0.59) appeared to be most effective at reducing PTSD symptoms post-treatment v. waitlist, followed by non-TF-CBT, TF-CBT combined with a selective serotonin reuptake inhibitor (SSRI), SSRIs, self-help without support and counselling. EMDR and TF-CBT showed sustained effects at 1-4-month follow-up. EMDR, TF-CBT, self-help with support and counselling improved remission rates post-treatment. Results for other interventions were either inconclusive or based on limited evidence. CONCLUSIONS: EMDR and TF-CBT appear to be most effective at reducing symptoms and improving remission rates in adults with PTSD. They are also effective at sustaining symptom improvements beyond treatment endpoint. Further research needs to explore the long-term comparative effectiveness of psychological therapies for adults with PTSD and also the impact of severity and complexity of PTSD on treatment outcomes

State of the science:Eye movement desensitization and reprocessing (EMDR) therapy

Eye movement desensitization and reprocessing (EMDR) therapy is an evidence-based psychotherapy for posttraumatic stress disorder (PTSD), with support from more than 30 published randomized controlled trials (RCTs) demonstrating its effectiveness in both adults and children. Most international clinical practice guidelines recommend EMDR therapy as a first-line treatment for PTSD. This paper describes the current state of the evidence for EMDR therapy. We begin with a brief description of EMDR therapy and its theoretical framework. Next, we summarize the scientific support for its efficacy, effectiveness, and safety and discuss its applicability across cultures and with diverse populations. We conclude with suggestions for future directions to develop the research base and applications of EMDR therapy.</p

Development of a training programme in individual case formulation skills and a scale for assessing its effectiveness

Background. The ability to formulate presenting problems in psychotherapy is widely acknowledged, but little is known about the skills involved. Treatment manuals are necessarily directed to the general form of a problem and need to be invidualised to the specific needs and circumstance of someone seeking treatment through formulation. The individual case formulation (ICF) approach is based on the functional analysis tradition within behavior therapy but aims to employ clinical descriptions that are theory-free. Formulations are depicted in diagrams constructed according to a set of basic conventions. Aims. Following on previous preparatory studies, the present paper reports on a test of whether this method of analysis and representation could be taught and if the quality of the resulting diagrams could be reliably rated. Method. Participants (N = 40) participated in a training course in formulation for posttraumatic stress disorder that was either self administered or presented live online. Results. A draft rating scale was refined in the course of rating the resulting formulation diagrams and basic inter-rater reliability established, despite a relatively high rate of formulations that did not meet minimal standards. Exploratory analyses examined the relation of derived scores to participant professional characteristics. Discussion. Results of the study support further development of the ICF approach

Clinicians' perspectives on retraumatisation during trauma-focused interventions for post-traumatic stress disorder: A survey of UK mental health professionals.

Concerns regarding retraumatisation have been identified as a barrier to delivering trauma-focused therapy for post-traumatic stress disorder (PTSD). We explored clinicians' understanding of what constitutes potential signs of retraumatisation (PSoR), reported incidences of witnessing retraumatisation, use of (and confidence in) therapies for PTSD, fear of retraumatisation during therapy for PTSD, and whether having witnessed retraumatisation was associated with these variables. We surveyed 348 clinicians. There was variation in what clinicians viewed as PSoR. Retraumatisation was reported by clinicians in 3.4 % of patients undergoing trauma-focused therapy for PTSD. A variety of trauma-focused and non-trauma-focused therapies were routinely used, yet 14.4 % reported not using trauma-focused therapy. There was a significant negative correlation between participants' highest reported confidence in trauma-focused therapy and endorsement of PSoR (r = -.25) and fear of retraumatisation (r = -.28). Mean fear of retraumatisation was 30.3 (SD=23.4; a score we derived from asking participants out of 100 how much they worry about trauma-focused therapy being harmful in its own right/leading to a worsening of PTSD symptoms). Participants who had witnessed retraumatisation reported significantly greater endorsement of PSoR (d=.69 [95 % CI .37, 1.02]) and fear of retraumatisation (d=.94 [95 % CI .61, 1.26]). Confidence in using therapies for PTSD was varied and related to how clinicians understood retraumatisation. Retraumatisation is uncommon, but there is variability in clinicians' interpretation of what retraumatisation is, and its utility warrants research

Imagery re-scripting for PTSD: session content and its relation to symptom improvement

Imagery rescripting (ImRs) is a therapy technique that, unlike traditional re-living techniques, focuses less on exposure and verbal challenging of cognitions and instead encourages patients to directly transform the intrusive imagery to change the depicted course of events in a more desired direction. However, a comprehensive account of how and in what circumstances ImRs brings about therapeutic change is required if treatment is to be optimised, and this is yet to be developed. The present study reports on the development of a coding scheme of ImRs psychotherapy elements identified in the literature as potential ImRs mechanisms. The codes were assessed in relation to short-term outcomes of 27 individuals undergoing ImRs for post-traumatic stress disorder. The timing of the change in the image, degree of activation of the new image and associated cognitive, emotional and physiological processes, self-guided rescripting, rescript believability, narrative coherence and cognitive and emotional shift were identified as being related to symptom change and so are potentially important factors for the re-scripting process
