Understanding experiences of psychedelic treatments for eating disorders: a meta-synthesis of qualitative studies.

Anxiety and Disordered Eating

BACKGROUND: Eating disorders seriously affect both physical health and psychosocial functioning. Breaking the confines of an eating disorder requires engagement in a multifaceted recovery process. OBJECTIVE: This article provides a synthesis of 12 qualitative research studies with various eating disordered populations (anorexia nervosa, bulimia nervosa, binge eating disorder, eating disorder not otherwise specified, and other specified feeding and eating disorders) to elucidate the recovery process from the perspective of those who have overcome the disease. METHOD: A metasynthesis of qualitative studies was conducted using Noblit and Hare's metaethnographic methodology. RESULTS: Five overarching themes emerged from the data: (1) the eating disorder as a life jacket, (2) drowning: recognizing consequences, (3) treading the surface: contemplating recovery, (4) swimming: the path toward recovery, and (5) reaching recovery: a sense of freedom. CONCLUSIONS: Eating disorder treatment often entails a cycle of transitions before recovery occurs. Synthesizing the experiences from the perspective of individuals who have overcome an eating disorder presents a unique understanding of the treatment and recovery process.

To describe changes in physical activity (PA) and exercise dependence score during treatment of eating disorders (ED), and to explore correlations among changes in PA, exercise motivation, exercise dependence score and ED psychopathology in excessive and non-excessive exercisers. Thirty-eight adult females receiving inpatient treatment for anorexia nervosa, bulimia nervosa or ED not otherwise specified participated in this prospective study. Assessments included accelerometer assessed PA, Exercise Dependence Scale, Reasons for Exercise Inventory, ED Examination, and ED Inventory. Amount of PA was significantly reduced in non-excessive exercisers during treatment, in excessive exercisers there was a trend towards reduced amount of PA from admission to discharge. In excessive exercisers, reduced ED psychopathology was correlated with reduction in exercise dependence score and perceived importance of exercise to regulate negative affects, but not with importance of exercise for weight/appearance. These associations were not found in non-excessive exercisers. Excessive exercise is an important issue in longstanding ED, and the excessive exercising patients need help to develop alternative strategies to regulate negative affects.

The ethics of exercise in eating disorders: Can an ethical principles approach guide the next generation of research and clinical practice?

A survey of Registered Dietitian Nutritionists who provide care to clients with eating disorders: Implications for education, training and clinical practice

ObjectiveQualitative studies report that autistic women have poor experiences when being treated for an eating disorder (ED) and express that ED services are not appropriately tailored to meet their needs. It is unclear whether their experience differs to other women accessing ED services. The aim of the current study was to compare autistic and non‐autistic women's ED illness history and experiences in ED services.MethodAn online survey about ED illness history and their experience with ED treatment was completed by 46 autistic women with a restrictive ED and 110 non‐autistic women with a restrictive ED.ResultsDespite some similarities, there were three key differences in the experiences reported by autistic and non‐autistic women. First, autistic women reported a longer duration of ED and being diagnosed with an ED at a younger age than non‐autistic women. Second, autistic women reported accessing a broader range of healthcare settings and ED treatments than non‐autistic women when being treated for an ED. Finally, autistic women rated their experiences of inpatient care, dietetic input, and cognitive behavioural therapy (CBT) as significantly less beneficial than non‐autistic women when being treated for an ED.ConclusionThese findings increase understanding of autistic women's ED experience and can help to shape ED services and treatments to better accommodate the needs of their autistic clients.

Representation of the body is a nuclear aspect of self-image. Body representation includes both subjective and intersubjective experiences. The importance of visual body representation in our social life is demonstrated by the time we spend to take care of our physical appearance, including use of plastic surgery, as well as by the severe mental disorders associated to its alteration, including eating disorders (EDs) and body dysmorphic disorders. In spite of these issues, (neuro)psychological research on body representation has so far mainly focused on the body as a motor device, devoted to the perception of and interaction with objects. The complexity of factors involved in the development, maintenance, and plasticity of body image representations requires an integrated approach that facilitates the evaluation and treatment of EDs with novel, evidence-based, and more efficacious protocols. This special issue of European Psychologist aims to advance such an integrative approach, with a collection of papers that gather different perspectives on the phenomenological, cognitive, (neuro)psychological, and cultural aspects of body representation disorders.

Objective To explore mental health associations during eating disorder (ED) treatment. Based on the dual-continua model of mental health, general and ED-specific psychopathology, as well as emotional, psychological, and social well-being were considered as mental health domains. Method Network analyses with panel data were applied to explore within- (temporal and contemporaneous networks) and between-person effects in a sample of 1250 female ED patients during 12 months of outpatient treatment. The associations between the domains and their centrality were examined. Autoregressive and cross-lagged effects were also estimated. Results ED psychopathology was the most central domain in the temporal network. ED psychopathology changes predicted further ED psychopathology changes and small changes in the other domains. Weak bi-directional associations were found between changes in the well-being domains and general psychopathology. In contrast to the temporal network, ED psychopathology was the least central and psychological well-being the most central domain in the contemporaneous and between-subjects networks. This suggests a central role of psychological well-being for experiencing mental health within time points. Conclusions ED psychopathology may change relatively independent from other mental health domains. Well-being domains may be considered as more stable aspects of mental health.

Anhedonia, a transdiagnostic symptom referring to the loss of ability to experience pleasure, is heightened across eating disorder (ED) diagnoses. This study aimed to assess whether anhedonia changes during ED treatment and explore how changes in anhedonia relate to treatment outcome. Adults and adolescents in a partial hospitalization program for EDs (N=499) completed the Eating Disorders Examination Questionnaire (EDE-Q) and the anhedonia subscale of the Beck Depression Inventory (BDI) at admission and discharge. Anhedonia scores significantly decreased from admission to discharge. Anhedonia at admission was also significantly different across ED diagnostic groups. To examine how study variables related to discharge EDE-Q scores, a hierarchical linear regression was conducted with demographic, diagnostic, and medication variables in the first step, anhedonia and EDE-Q scores at admission added to the second step, and anhedonia at discharge added to the final step. Greater anhedonia at discharge was related to higher EDE-Q scores at discharge. Our findings suggest that anhedonia changes significantly over the course of intensive treatment and changes in anhedonia relate to ED symptoms at discharge. Future research is needed to determine whether specifically targeting anhedonia in ED treatment may influence treatment outcomes. The findings from this study suggest that anhedonia may decrease during eating disorder (ED) treatment, and greater anhedonia may relate to elevated ED symptoms. These results provide support for the continued study of anhedonia in ED samples and indicate that anhedonia should be explored as a potential target for novel ED treatments.

Introduction and purpose: Eating disorders belong to the group of mental diseases characterized by significant somatic complications and high mortality. There is a common opinion that these disorders mainly affect women. Such assumptions may result in limited knowledge of the diagnosis and treatment of an eating disorder in the male population. The aim of this study is to summarize the current knowledge about eating disorders among men, including binge eating disorder (BED), anorexia nervosa (AN) and bulimia nervosa (BN). Description of the state of knowledge: It turns out that the problem of eating disorders among the male sex is not so rare- it is estimated that approximately 10 million US men will experience an eating disorder at some point in their lives. The most common eating disorder among men appears to be binge eating disorder (BED). Men are also more likely to report binge eating than women. AN and BN occur much less frequently than BED in the male population. The symptoms of anorexia nervosa and bulimia nervosa may differ between men and women. More and more often we observe a development of a certain type of muscle dysmorphia among men, the so-called “reverse anorexia". Eating disorders carry a number of medical complications such as cardiac disorders, electrolyte disturbances, digestive problems and skeletal disturbances. Therapeutic interventions in the treatment of male eating disorders should take into account gender-specific problems. Conclusions: The real number of men suffering from eating disorders may be underestimated due to the neglect of the problem in the context of the male gender. It also results in poorly developed diagnostic and support schemes for men struggling with this problem. More research is needed on the topic of eating disorders in this group of patients as it will help to develop better diagnostic and therapeutic regimens adapted to the male gender.

This chapter includes a review of literature on eating disorder (ED) assessment and treatment in athletes to identify the best practices for clinical sport psychologists. First, the authors (a licensed psychologist who is a certified mental performance consultant and a registered dietitian nutritionist with expertise treating athletes with EDs) describe a multidisciplinary ED treatment approach and identify core treatment providers for athletes’ best practice care. Next, a comprehensive review of screening and assessment tools to detect ED risk, low energy availability, and other relevant psychological and behavioral factors is presented. The authors endorse specific assessment tools that are reliable, valid, and appropriate for athletes, along with guidance on who and when to screen. In addition, the limited but emerging athlete-specific ED treatment research is reviewed, with a focus on sport-specific factors that influence athletes’ ED recovery. Common concerns that arise during competitive athletes’ ED treatment are discussed such as the need to reduce practice or competition, the role of exercise during treatment, and return-to-play decisions. Athlete-specific treatment recommendations and resources to locate qualified multidisciplinary treatment team members are provided. Finally, the authors articulate limitations of the existing literature, identifying future directions for research on ED screening and treatment for athletes.

BackgroundDespite the disabling nature of eating disorders (EDs), many individuals with ED symptoms do not receive appropriate mental health care. Internet-based interventions have potential to reduce the unmet needs by providing easily accessible health care services.ObjectiveThis study aimed to investigate the effectiveness of an Internet-based intervention for individuals with ED symptoms, called “Featback.” In addition, the added value of different intensities of therapist support was investigated.MethodsParticipants (N=354) were aged 16 years or older with self-reported ED symptoms, including symptoms of anorexia nervosa, bulimia nervosa, and binge eating disorder. Participants were recruited via the website of Featback and the website of a Dutch pro-recovery–focused e-community for young women with ED problems. Participants were randomized to: (1) Featback, consisting of psychoeducation and a fully automated self-monitoring and feedback system, (2) Featback supplemented with low-intensity (weekly) digital therapist support, (3) Featback supplemented with high-intensity (3 times a week) digital therapist support, and (4) a waiting list control condition. Internet-administered self-report questionnaires were completed at baseline, post-intervention (ie, 8 weeks after baseline), and at 3- and 6-month follow-up. The primary outcome measure was ED psychopathology. Secondary outcome measures were symptoms of depression and anxiety, perseverative thinking, and ED-related quality of life. Statistical analyses were conducted according to an intent-to-treat approach using linear mixed models.ResultsThe 3 Featback conditions were superior to a waiting list in reducing bulimic psychopathology (d=−0.16, 95% confidence interval (CI)=−0.31 to −0.01), symptoms of depression and anxiety (d=−0.28, 95% CI=−0.45 to −0.11), and perseverative thinking (d=−0.28, 95% CI=−0.45 to −0.11). No added value of therapist support was found in terms of symptom reduction although participants who received therapist support were significantly more satisfied with the intervention than those who did not receive supplemental therapist support. No significant differences between the Featback conditions supplemented with low- and high-intensity therapist support were found regarding the effectiveness and satisfaction with the intervention.ConclusionsThe fully automated Internet-based self-monitoring and feedback intervention Featback was effective in reducing ED and comorbid psychopathology. Supplemental therapist support enhanced satisfaction with the intervention but did not increase its effectiveness. Automated interventions such as Featback can provide widely disseminable and easily accessible care. Such interventions could be incorporated within a stepped-care approach in the treatment of EDs and help to bridge the gap between mental disorders and mental health care services.Trial RegistrationNetherlands Trial Registry: NTR3646; http://www.trialregister.nl/trialreg/admin/ rctview.asp?TC=3646 (Archived by WebCite at http://www.webcitation.org/6fgHTGKHE)

There is a growing call to identify specific outcome predictors in real-world eating disorder (ED) treatment settings. Studies have implicated several ED treatment outcome predictors [rapid response (RR), weight suppression, illness duration, ED diagnosis, and psychiatric comorbidity] in inpatient settings or randomized controlled trials of individual outpatient therapy. However, research has not yet examined outcome predictors in intensive outpatient programs (IOP). The current study aimed to replicate findings from randomized controlled research trials and inpatient samples, identifying treatment outcome predictors in a transdiagnostic ED IOP sample. The current sample comprised 210 consecutive unique IOP patient admissions who received evidence-based ED treatment, M(SD)Duration = 15.82 (13.38) weeks. Weekly patient measures of ED symptoms and global functioning were obtained from patients' medical charts. In relative weight analysis, RR was the only significant predictor of ED symptoms post treatment, uniquely accounting for 45.6% of the predicted variance in ED symptoms. In contrast, baseline ED pathology was the strongest unique predictor of end-of-treatment global functioning, accounting for 15.89% of predicted variance. Baseline factors did not differentiate patients who made RR from those who did not. Consistent with findings in more controlled treatment settings, RR remains a robust predictor of outcome for patients receiving IOP-level treatment for EDs. Future work should evaluate factors that mediate and moderate RR, incorporating these findings into ED treatment design and implementation. Level IV, uncontrolled intervention.

Having both an eating disorder (ED) and borderline personality disorder (BPD) is associated with heightened clinical complexity, high levels of distress, and challenges in treatment. This study sought to qualitatively investigate the experiences of women with an ED and comorbid BPD as they undergo ED treatment, aiming to better understand factors that shape their perceptions of care. Fourteen women with both an ED and BPD in treatment at a public-sector ED clinic were recruited to participate in an open-ended qualitative interview about their lived treatment experiences. Five overarching themes (with seven subthemes) emerged from the qualitative analysis: (1) Difficulties with emotions as a key factor underlying both ED and BPD; (2) Perceptions of BPD in ED maintenance and treatment; (3) Relational dynamics in treatment; (4) Treatment is "never enough"; and (5) The importance of treating the ED and BPD together. This study highlights the lived experiences of women with both an ED and BPD. Patients expressed the need for ED treatment to target emotion dysregulation, interpersonal difficulties, and their attachment to their therapists and to treatment. This study provides insights into the experiences of patients with BPD of ED treatment that may help guide the approach to care in such individuals.

BackgroundExcessive exercise is recognized as a predictor of poor outcome in eating disorders. However, little is known about how excessive exercise might affect the treatment process. The aim of this study was to describe process of weekly changes in eating disorder psychopathology, general psychopathology and exercise, and the possible interactive effects of excessive exercise on these changes during inpatient treatment of longstanding eating disorders.MethodsEighty-four patients meeting the DSM-IV criteria for Anorexia Nervosa, Bulimia Nervosa, or Eating Disorders Not Otherwise Specified received inpatient cognitive-behavioural therapy including, physical activity and nutritional counselling treatment over 12 weeks. Excessive exercise was defined as having ≥6 episodes of driven exercise during week 1 of treatment. Excessive exercisers received one additional session of individual counseling with the clinical exercise physiologist. The study used repeated measurements during treatment and collected measures of eating disorders: psychopathology (EDE-Q), general psychopathology (SCL-5), and frequencies of exercise and body mass index (BMI). Statistical analysis was performed using repeated measures ANOVA.ResultsBoth eating disorders and general psychopathology were reduced from admission to discharge in excessive exercisers and non-exercisers. There was an overall interaction effect between time (week) and excessive exercise for the process of exercise and eating disorders psychopathology reduction. This interaction effect was also found in week 10 vs 11 regarding general psychopathology. The excessive exercisers showed steep reduction at first, followed by a smaller increase towards the end of treatment in both eating disorder and general psychopathology; this pattern was not found among the non-exercisers.ConclusionThe process of change in exercise and psychopathology during inpatient treatment of longstanding eating disorders differs across excessive and non-excessive exercisers. Although excessive exercisers were given special attention for their exercise cognition and behavior during treatment, it is apparent that this part of treatment must be further developed.
