Although 4.7% of adolescents suffer from symptoms of bulimia nervosa (BN), only 1/5 seek treatment. Hesitation to seek treatment is likely related to ego-syntonicity and fear of disclosing symptoms to parents and clinicians. Furthermore, the physical symptoms of BN often go unnoticed by parents and clinicians. In order to eliminate the barriers that prevent adolescents from seeking treatment, this study will offer anonymous access to online self-help cognitive behavioral therapy (CBT) for BN. Online CBT (traditional, non-anonymous delivery) has been found to be effective and acceptable treatment for adolescents with BN. Furthermore, in adults, this method has been found to be as effective as specialized treatments, and more cost efficient. To remain anonymous and accessible, the self-help approach in this study will be provided in a non-guided, or pure format (only online sessions). Studies support that a pure self-help methodology is as effective as a guided version. Although anonymity may improve accessibility, this study design could also pose challenges in areas such as recruitment, treatment completion and obtaining adequate informed consent. Therefore, before embarking on a larger randomized control trail, we would like to propose a small, non-controlled feasibility study to assess potential issues in these areas. Primary hypotheses: Recruitment: Based on communication with public health nurses in the high schools we plan to recruit from, we hypothesize that it is feasible to recruit 1-5 adolescents over a 4-month period from each of the 5 schools, and 1-5 from social media outlets such as Instagram, Twitter, Facebook for a total of 5 participants over a 4-month period. Treatment completion: Based on pervious studies of self-help for adolescent bulimia, we hypothesize that approximately 15% of participants will not complete any sessions, and many will only complete about half of the sessions. Informed consent: Based on information from large randomized control studies in the UK, we hypothesize that adolescents will be capable of providing online consent, and that we will be able to adequately obtain consent without verbally communicating with participants. Secondary hypothesis: We hypothesize a non-guided (pure) version of online CBT-BN offered in an anonymous manner will decrease BN symptoms after treatment completion, and at 3-month follow-up compared to baseline.
Introduction: The purpose of this research is to develop a new component for cognitive-behavioral treatment (CBT), empirically validated, for binge eating behavior in patients with bulimia nervosa (BN) and binge eating disorder (BED), by means of cue-exposure therapy (CET) with virtual reality. While CBT is an effective treatment for these eating disorders, an important percentage of patients do not improve despite treatment. It is necessary to explore how to enhance the effectivity of usual treatments with the incorporation of new technologies and procedures. The innovation of this investigation is based on the use of VR for cue-exposure therapy, which has been found effective with patients resistant to conventional treatments (CBT and pharmacological intervention), and seeks to enhance this efficacy by increasing possibilities of generalization and providing more useful tools to clinicians, diminishing the logistic complications of the exposure to real cues (food). Participants: 60 patients with a diagnosis of BN or BED according the DSM-5 who had been proposed for participation in the study by their referral mental health's professional after conducting unsuccessfully a first level treatment (CBT structured intervention) at the clinical sites involved will participate in the study. Procedure: Participants with active episodes of binge eating (and purging, in the case of BN) during the last 2 weeks of the structured intervention of CBT will be provided with detailed information about the study. All patients who agree to participate in the study and who sign the informed consent form will be randomly assigned to one of the two second-level treatment conditions: virtual reality based cue-exposure therapy (VR-CET) or additional cognitive-behavioral treatment (A-CBT). Both second-level treatment conditions consist of six 60-minute sessions that are held two times per week over a period of three weeks. In an interview setting, all of the participants will be administered several questionnaires (BN, DT and BD subscales of EDI-3, FCQ-T/S, and STAI-Y) and participants assigned to the VR-CET will also be exposed to various types of virtual foods in different virtual environments (kitchen, dining-room, bedroom, and café) where they will be asked about their food cravings and anxiety experienced in each situation to develop a proper exposure hierarchy according to the specific characteristics and needs of each patient.
Yoga facilitates the treatment of eating disorders by decreasing symptom severity over time.
The presence of binge eating (BE) is a core feature of bulimic syndromes. Binge eating disorder (BED) is a new category in DSM-5 highly associated with higher body mass index (BMI). The neural mechanisms that underlie BE are of great interest in order to improve treatment interventions. Brain mechanisms underlying drug and food craving are suggested to be similar. These mechanisms demonstrated hyperactivity in the orbitofrontal and anterior cingulate cortex and lack of regulatory influence from lateral prefrontal circuits. Several novel studies began to assess the potential benefits of brain stimulation in reducing craving and associated addictive behaviors with promising results. Previous findings testing a one-off session of repetitive transcranial magnetic stimulation (rTMS) in healthy women identified as strong cravers and individuals with bulimia nervosa or bulimic-type eating disorders reported reduction of food craving and BE, providing evidence to support a broader and deeper investigation of the benefits associated with rTMS. Importantly, the use of brain imaging studies contributes to the understanding of psychiatric disorders and underlying mechanisms being target by the rTMS intervention. Objectives: The primary aim is to investigate the effects of rTMS over BE frequency. Secondary aims include the evaluation of the effects of rTMS on food craving, body weight, brain activity, cognition, general psychopathology, hormonal regulation and neurobiological markers. Methods: Sixty obese females with BED will be randomized to receive 20 sessions of rTMS (n=30) or placebo (n=30) scattered 3 days/week. Expected Results: Primarily it is expected that rTMS intervention will decrease BE frequency. Consequently, body weight will be reduced. It is also expected that food craving be decreased, cognitive performance be enhanced, and neurobiological markers be improved.
"Eating disorders" includes anorexia nervosa, bulimia nervosa, binge eating and other specified feeding or eating disorder (OSFED). Common to all is the intensively occupation to control food intake, body image and body weight. Most people with this kind of disorder don't reach for professional help, or there may be more than 4 years before they do. Cognitive behavior therapy is the foremost method of treatment of eating disorders, but up to 30-50% of the patients don't respond to this. The investigators find it important to identify science based alternatives of therapy, as this may reduce the health concern, and broaden the choice of therapy methods. A former study by Sundgot-Borgen et al in 2002, found guided physical activity to reduce symptoms of bulimia nervosa just as good as the traditional cognitive therapy. The primary objective of the project is to see whether the combination of physical exercise and dietary therapy is more effective in treating eating disorders, than cognitive therapy. Secondly, the investigators want to see whether there are any differences with regard to the individual satisfaction of treatment method, and to associated costs. Interviews with a sufficient number of participants from the PED-t arm to meet data saturation criteria, and all theraphists in the new treatment offer, will give uniqe insight to experiences with the treatment method and the delivery of treatment.
The purpose of the study is to test a newly developed individual psychotherapy treatment for binge eating disorder in adults. This treatment is a type of individual psychotherapy called Integrative Cognitive-Affective Therapy (ICAT) that focuses on helping people change their behaviors, feelings, thoughts about themselves, and relationships. This new treatment is being compared to an existing treatment called Cognitive-Behavior Therapy-Guided Self Help (CBTgsh), which focuses on changing behavior patterns through the use of reading and homework assignments along with sessions with a therapist. The primary hypothesis of this investigation is that ICAT will be associated with greater reductions in binge eating at end of treatment and follow-up compared to CBTgsh.
Binge Eating Disorder (BED) may be associated with he development of obesity. However, the pathogenesis of BED is currently unclear, thus making the development of treatment and prevention strategies for BED difficult. Differences in the mechanisms regulating food intake may go some way to reveal potential mechanisms for BED.The purpose of this study is to investigate the responses of key gut-derived hormones that are associated with the regulation of food intake and functional brain activity to food cues using fMRI in BED patients and weight matched controls.
To evaluate maintenance of efficacy based on time to relapse between SPD489 (50 or 70mg) and placebo, as measured by the number of binge days (defined as days during which at least 1 binge episode occurs) per week as assessed by clinical interview based on subject diary and Clinical Global Impression - Severity (CGI-S) scores for patients who responded to SPD489 by the end of the Open-label Treatment Phase.
This is a pilot study investigating if cycloserine (DCS; a learning enhancement medication) augments exposure therapy for food anxiety in patients with anorexia and bulimia nervosa. The investigators expect that (a) exposure therapy will reduce anxiety (b) anxiety will be reduced more in the DCS relative to placebo condition (c) participants in the DCS condition will have a greater increase in Body Mass Index.
