The Eva-PED-t project will evaluate implementation of a new therapy for eating disorders, called PED-t (Physical Exercise and Dietary therapy), in a new treatment arena for such illnesses. By this, Eva-PED-t evaluates effectiveness- and efficacy outcomes, with the latter highlighting both the user-, the therapists- and the management perspectives. The research group behind this initiative comprises the founders of the PED-t, and holds extensive expertise on research methodology, eating disorders, health science, and exercise medicine, affiliated high-ranked research-intensive universities. Previous documentation of poor implementation of evidence-based knowledge in public health services reveal poor or no translation of new research findings for improved screening, treatment or medical procedures into real life settings. This may impair public health service outcomes, as less effective or ineffective treatment or procedures are routinely preferred. In a randomized controlled trial, the Eva-PED-t partnership recently found a new therapy for eating disorders (PED-t) to be comparable effective to the currently recommended treatment (NCT02079935). Specific advantages with PED-t, are the use of professionals not currently used in therapy of mental disorders, and the efficiency of arranging therapy in groups, hence effectively dealing with the high request for therapy. The Eva PED-t collaborative is motivated by the knowledge of high prevalence of mental illnesses, for which there is a need to improve treatment access and -efficiency. Adding to this scenario, is the new and more prevalent diagnosis of eating disorders, binge eating disorder, for which specialized health services have no prioritization for treatment. Addressing requirements for improved therapy access demands investigation of new treatments and new ways of delivery. The PED-t responds to this request, still recommendation for a broad implementation necessitate exploration of implementation strategies and experiences.
Both behavioral, psychological, and cognitive differences related to social cognitive function have been related to illness-state in eating disorders, but interventions that directly target these problems are limited. This pilot intervention explores whether a brief art-therapy team-building intervention coupled with psychoeducation about social behavior can change self-concept or clinical symptoms in patients with eating disorders. Participants will complete pre-treatment assessments related to social behaviors and clinical symptoms, attend four two-hour group sessions, and provide two follow-up post-treatment assessments at 1-4 weeks after the treatment and 3-5 months later. Comparisons between the pre-intervention data and the first follow-up will be the primary outcome measures. The primary hypotheses are that participants will show increases in self-esteem and positive self-attributions and decreases in eating disorder symptoms after the intervention. The secondary hypothesis is that other clinical symptoms (depression, anxiety) will be improved after the intervention. Feedback from participants about their experience with the study will assess perceived benefits as well as acquisition of the psychoeducation targets.
This study evaluates the effectiveness of a web-based intervention specifically designed for patients with Bulimia Nervosa (BN) in a blinded randomized controlled trial. After a sign-up process, a diagnostic interview, and a baseline assessment, eligible participants will be randomly allocated either to (1) an intervention group including the online web-based intervention for BN or (2) a waitlist control group with delayed access to the intervention (12 weeks). The program comprises six mandatory weekly sessions and six modular specialization areas resulting in a treatment period of 12 weeks. Minimal guidance is provided via a chat function. Assessments will be conducted at pretreatment (study entrance), six weeks after baseline (mid-treatment), and 12 weeks after baseline (post-treatment). The investigators expect that the intervention group will show lower frequencies of binge eating episodes and compensatory behavior as the primary outcome variables after the 12 weeks of treatment compared to a waitlist control condition. Moreoever, the investigators assume that there will be a higher reduction in global eating disorder symptoms, comorbid psychopathology, and a higher increase in well-being and self-esteem over 12 weeks in the intervention group compared to the waitlist control group. Finally, the investigators expect that the intervention group will demonstrate a significantly higher reduction in functional impairment, substantially better restoration of work capacity, and an improved ability to regulate emotions after the 12 weeks of treatment.
In the current study, the investigators will revise our existing 10-session group RRT treatment manual to specifically address the challenges in building social support and enhancing both momentary and sustained reward during the COVID-19 pandemic (Preliminary Aim 1). In months 2-18, the investigators will conduct a small pilot RCT that will randomize individuals to receive either 10-sessions of RRT (n=30) or supportive therapy (n=30), both delivered as group-treatments via videoconferencing software. The specific aims of the current study are to confirm the feasibility and acceptability of RRT for EDs (Primary Aim 1), evaluate the ability of RRT to engage critical targets including reward to day-to-day life activities, reward to palatable foods, social isolation, and loneliness (Primary Aim 2), and provide preliminary estimates of efficacy in reducing ED symptoms at both post-treatment and a 3-month follow-up (Primary Aim 3). the investigators will also evaluate the impact of RRT on secondary outcome variables including depression, substance use, and quality of life (Secondary Aim 1).
The purpose of this study is to investigate areas of the brain responsible for appetite regulation. More specifically, the investigators would like to study changes in brain activation, e.g., changes in blood flow and oxygen use of the brain, during two different states: Once when the participants are hungry, and once when the participants are not hungry. The aim is to find out more about the neurobiology of Anorexia and Bulimia Nervosa by comparing women who never had an eating disorder with women who have recovered from Anorexia or Bulimia Nervosa.
This project proposes to perform a pilot study of fMRI targeted Dorsomedial Prefrontal Cortex repetitive transcranial magnetic stimulation (DMPFC-rTMS) on individuals diagnosed with Bulimia Nervosa (BN) and Anorexia Nervosa (AN). The DMFPC is a novel target for rTMS, is heavily implicated in the regulation of mood and affect, and has been suggested to be involved in AN, BN, major depression, OCD, and PTSD. Improved function in this area might lead to reduced AN and BN symptoms, such as bingeing, purging, and over-activity, perhaps by improved regulation of mood and affect. Improvements in important areas of comorbidity might allow for better response to intensive treatment for AN and BN, and reduce relapse rates after such treatment. The DMPFC may be a more appropriate target for compared to the Dorsolateral Prefrontal Cortex (DLPFC), which has typically been the focus of stimulation in the past. Our initial preliminary pilot work has noted unexpected and significant improvements in some core ED symptoms (bingeing and purging) and in important areas of comorbidity (OCD and PTSD), along with expected improvements in mood. These changes have allowed some treatment resistant patients to either complete intensive treatment or be successful in maintaining their progress post intensive treatment. Subjects will receive up to 30 sessions of bilateral DMPFC-rTMS. Response will be evaluated clinically, via psychometric measures, and pre and post fMRI.
The overarching intention of the Eating Disorder Genetics Initiative (EDGI) is to lay the foundation for all future genomic discovery in eating disorders--anorexia nervosa (AN), bulimia nervosa (BN), and binge-eating disorder (BED)--by exploring both genetic and behavioral factors. To do this, information will be collected from 4000 people who have provided DNA samples for the Anorexia Nervosa Genetics Initiative (ANGI) and the same information and DNA will be collected from an additional 16,000 people. The goal is to better understand eating disorders and how they relate to each other so that better treatments can be developed.
Eating disorders are difficult to treat. Some forms of treatment have already been found to be effective, nevertheless chronicity is a major problem. For example, both cognitive behavioral therapy and family therapy (FBT; family-based treatment) appear to be effective treatment methods, in which FBT distinguishes itself primarily in its long-term effect. However, eating disorders persist in 20 to 25 percent of cases, only 46 percent of patients with Anorexia Nervosa fully recover and one third only partially improve. Since the mortality rate of this mental disorder is particularly high, it is necessary to keep looking to improve treatment. Because emotion regulation problems play an important role in the cause and maintenance of an eating disorder, more emotion-focused therapies may improve treatment outcome. Dialectical Behavioral Therapy is a treatment that has a strong focus on emotions regulation, but so far only limited evidence has been found for the effectiveness of this type of therapy in eating disorders. Some studies show that art therapy (AT; art therapy) can contribute to a more adaptive regulation of emotions. However, this type of therapy has not been studied in the context of eating disorders yet. AT is an experiential form of therapy in which art techniques and supplies (including drawing, painting, clay, etc.) are used methodically with a therapeutic purpose. The idea that creative expression can perpetuate or improve mental well-being has been accepted worldwide for many years. Despite the long history of practical applications, to date little evidence exist on the effectiveness of this form of treatment. There's growing worldwide interest in scientific research and the emphasis on evidence-based practice (EBP) for this form of treatment. In a recent study, Lock and colleagues compare AT with cognitive remediation therapy (CRT) and the added value of both in a sample of adolescents with anorexia nervosa combines with obsessive-compulsive problems. Both CRT and AT are offered in this study in combination with family based therapy (FBT). The group in which the combination of FBT and AT was offered yielded better results than those in which FBT is combined with CRT. Study hypothesis: the investigators expect that complementing treatment as usual (TAU) with art therapy (AT) will lead to a decrease in emotion regulation problems in patients with an eating disorder in comparison with TAU only, without AT.
This pilot study experimentally manipulates ovarian hormones to examine the direct impact of estrogen (E2) and progesterone (P4) on binge eating symptom burden and the behavioral reward response in women with bulimia nervosa (n=15). This is completed by taking medications that change ovarian hormone levels. This line of research could lead to the development of pharmacological interventions developed to target specific areas of the brain, brain receptors, or pathways identified to be involved in the mechanism underlying ovarian hormone change and binge eating.
