Treating PTSD with Imagery Rescripting in underweight eating disorder patients: a multiple baseline case series study

The working mechanisms of imagery rescripting and eye movement desensitization and reprocessing: Findings from a randomised controlled trial

We studied the mechanisms of eye movement desensitization and reprocessing (EMDR) and imagery rescripting (ImRs). We hypothesized that EMDR works via changes in memory vividness, that ImRs works via changes in encapsulated beliefs (EB), and that both treatments work via changes in memory distress. Patients (N = 155) with childhood-related posttraumatic stress disorder (Ch-PTSD) received 12 sessions of EMDR or ImRs. The vividness, distress, and EB related to the index trauma were measured with the Imagery Interview. PTSD severity was assessed with the Impact of Events Scale-Revised and the Clinician-Administered PTSD Scale for DSM-5. We conducted mixed regressions and Granger causality analyses. EMDR led to initially stronger changes in all predictors, but only for distress this was retained until the last assessment. No evidence for vividness as a predictive variable was found. However, changes in distress and EB predicted changes in PTSD severity during ImRs. These findings partially support the hypothesized mechanisms of ImRs, while no support was found for the hypothesized mechanisms of EMDR. Differences in the timing of addressing the index trauma during treatment and the timing of assessments could have influenced the findings. This study provides insight into the relative effectiveness and working mechanisms of these treatments.

Treatment of patients with anorexia nervosa and comorbid post-traumatic stress disorder; where do we stand? A systematic scoping review

Objective

Comorbid post-traumatic stress disorder in patients with anorexia nervosa may negatively affect the course of anorexia nervosa treatment, which is already challenging. There are currently no guidelines or recommendations on concurrent treatment approaches for both anorexia nervosa and post-traumatic stress disorder. This systematic scoping review aims to explore the feasibility, acceptability and effectiveness of psychological trauma-focused treatment concurrently offered to underweight patients receiving anorexia nervosa treatment.

Method

A multi-step literature search, according to an a priori protocol was performed. Databases PubMed, Embase, APA PsycINFO, Web of Science, Scopus and Cochrane Central were searched up to September 19th 2022, and the search was rerun June 19th 2023. For quality assessment, Risk of Bias in Non-randomised Studies-of Interventions tool was used.

Results

The extensive search yielded 1769 reports, out of which only three observational pilot studies, both English and German, published between 2004 and 2022, could be included. The included studies reported on a total of 13 female participants between 16 and 58 years old, with anorexia nervosa or otherwise specified feeding or eating disorder, baseline BMI ranging between 14.6 and 16.5, who received concurrent anorexia and post-traumatic stress disorder treatment. In all participants, the emotional and cognitive functioning was sufficient to process the offered trauma-focused interventions, despite their significantly low body weight.

Discussion

The findings of this review identify a dearth of treatment research on knowledge of concurrent trauma-focused treatments for patients with anorexia nervosa. Refraining patients with anorexia nervosa from trauma-focused treatment may not be warranted.

Psychogenic Nonepileptic Seizures Associated with an Eating Disorder and PTSD Are Responsive to Cognitive Processing Therapy

Objective

Eating disorders (EDs) are often associated with prior histories of trauma, subsequent PTSD and related psychiatric comorbidities. There is a paucity of information about their relationship to somatic symptom disorders, specifically psychogenic nonepileptic seizures (PNES), a type of functional neurological symptom disorder or conversion disorder.

Methods

We report a case of a 39-year-old bisexual female with bulimia nervosa (BN), PTSD, recurrent major depressive disorder (MDD), cannabis use disorder, and PNES who responded to integrated trauma-focused treatment during residential ED treatment using cognitive processing therapy (CPT). Symptoms of ED, PTSD, major depression, and state-trait anxiety were measured using validated assessment instruments.

Results

During the course of CPT treatment, the patient's total scores on the PTSD Symptom Checklist for DSM-5 (PCL-5) went from 59 to 26, which is below the diagnostic threshold for PTSD. In addition, she demonstrated improvements in the Eating Disorder Examination Questionnaire (EDE-Q) Global Severity score, the Eating Disorder Inventory (EDI-2) total score, the Patient Health Questionnaire (PHQ-9) total score, the Spielberger State and Trait Anxiety Inventory scores, and the Eating Disorder Quality of Life (EDQOL) total score. Furthermore, her PNES also abated, and she remained seizure free for ∼1 year following discharge with the exception of one short seizure, per report of the patient.

Conclusion

The use of CPT as part of an integrated trauma-informed treatment approach during residential ED treatment was successful in a woman with PNES, BN, PTSD, MDD, and cannabis use disorder.

The integrated treatment of eating disorders, posttraumatic stress disorder, and psychiatric comorbidity: a commentary on the evolution of principles and guidelines

Psychiatric comorbidity is the norm in the assessment and treatment of eating disorders (EDs), and traumatic events and lifetime PTSD are often major drivers of these challenging complexities. Given that trauma, PTSD, and psychiatric comorbidity significantly influence ED outcomes, it is imperative that these problems be appropriately addressed in ED practice guidelines. The presence of associated psychiatric comorbidity is noted in some but not all sets of existing guidelines, but they mostly do little to address the problem other than referring to independent guidelines for other disorders. This disconnect perpetuates a "silo effect," in which each set of guidelines do not address the complexity of the other comorbidities. Although there are several published practice guidelines for the treatment of EDs, and likewise, there are several published practice guidelines for the treatment of PTSD, none of them specifically address ED + PTSD. The result is a lack of integration between ED and PTSD treatment providers, which often leads to fragmented, incomplete, uncoordinated and ineffective care of severely ill patients with ED + PTSD. This situation can inadvertently promote chronicity and multimorbidity and may be particularly relevant for patients treated in higher levels of care, where prevalence rates of concurrent PTSD reach as high as 50% with many more having subthreshold PTSD. Although there has been some progress in the recognition and treatment of ED + PTSD, recommendations for treating this common comorbidity remain undeveloped, particularly when there are other co-occurring psychiatric disorders, such as mood, anxiety, dissociative, substance use, impulse control, obsessive-compulsive, attention-deficit hyperactivity, and personality disorders, all of which may also be trauma-related. In this commentary, guidelines for assessing and treating patients with ED + PTSD and related comorbidity are critically reviewed. An integrated set of principles used in treatment planning of PTSD and trauma-related disorders is recommended in the context of intensive ED therapy. These principles and strategies are borrowed from several relevant evidence-based approaches. Evidence suggests that continuing with traditional single-disorder focused, sequential treatment models that do not prioritize integrated, trauma-focused treatment approaches are short-sighted and often inadvertently perpetuate this dangerous multimorbidity. Future ED practice guidelines would do well to address concurrent illness in more depth.

Eating disorder patients with and without PTSD treated in residential care: discharge and 6-month follow-up results

INTRODUCTION

We studied whether provisional posttraumatic stress disorder (PTSD) moderated discharge (DC) and 6-month follow-up (FU) outcomes of multi-modal, integrated eating disorder (ED) residential treatment (RT) based upon principles of cognitive processing therapy (CPT).

METHODS

ED patients [N = 609; 96% female; mean age (± SD) = 26.0 ± 8.8 years; 22% LGBTQ +] with and without PTSD completed validated assessments at admission (ADM), DC and 6-month FU to measure severity of ED, PTSD, major depressive disorder (MDD), state-trait anxiety (STA) symptoms, and eating disorder quality of life (EDQOL). We tested whether PTSD moderated the course of symptom change using mixed models analyses and if ED diagnosis, ADM BMI, age of ED onset and LGBTQ + orientation were significant covariates of change. Number of days between ADM and FU was used as a weighting measure.

RESULTS

Despite sustained improvements with RT in the total group, the PTSD group had significantly higher scores on all measures at all time points (p ≤ .001). Patients with (n = 261) and without PTSD (n = 348) showed similar symptom improvements from ADM to DC and outcomes remained statistically improved at 6-month FU compared to ADM. The only significant worsening observed between DC and FU was with MDD symptoms, yet all measures remained significantly lower than ADM at FU (p ≤ .001). There were no significant PTSD by time interactions for any of the measures. Age of ED onset was a significant covariate in the EDI-2, PHQ-9, STAI-T, and EDQOL models such that an earlier age of ED onset was associated with a worse outcome. ADM BMI was also a significant covariate in the EDE-Q, EDI-2, and EDQOL models, such that higher ADM BMI was associated with a worse ED and quality of life outcome.

CONCLUSIONS

Integrated treatment approaches that address PTSD comorbidity can be successfully delivered in RT and are associated with sustained improvements at FU. Improving strategies to prevent post-DC recurrence of MDD symptoms is an important and challenging area of future work.

Perspectives of underweight people with eating disorders on receiving Imagery Rescripting trauma treatment: a qualitative study of their experiences

BACKGROUND

The prognosis for underweight individuals with an eating disorder (ED) and posttraumatic stress disorder (PTSD) is worse than for their peers without these comorbid symptoms. This qualitative study explores the experiences of trauma-focused Imagery Rescripting (ImRs) therapy of underweight inpatients being treated for an ED.

OBJECTIVE

To test the feasibility and to improve ImRs by understanding the experiences and perspectives of people with an ED and PTSD who, when underweight, received ImRs as an adjunct to their inpatient ED treatment.

METHOD

To explore how underweight people with an ED experience and perceive ImRs, we used a qualitative study design involving semi-structured interviews with 12 participants. After analysis, the data were summarized and classified within a thematic framework that focused on experiences and improving the ImRs method.

RESULTS

The thematic analysis resulted in the following 6 main themes; (1) Expectations of ImRs; (2) Ability to participate in ImRs; (3) Effect of ImRs; (4) Experience of ImRs technique; (5) Conditions under which ImRs is given; (6) In depth-analysis. The results show that despite the fear of disappointment the participants appreciate addressing the PTSD and ED symptoms simultaneously. Further, results showed that it had been possible for them to attend ImRs but that the effects of ImRs were not uniformly perceived. Also, participants indicated that a caring context is important and that ImRs should not be scheduled immediately before a meal. Finally, the treatment generated hope.

CONCLUSIONS

The findings of this study demonstrated the feasibility of the integration of ImRs trauma treatment for individuals who are being treated in an ED inpatient treatment setting, and are in contrast to standard practice where the focus of inpatient treatment has been ED-symptom improvement without comprehensively addressing past traumatic experiences during an underweight phase.
