Filter by: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.
Anorexia Nervosa (AN) is considered as one of the most severe subtypes of eating disorders (ED), with important medical complications, high mortality rates, and high comorbidity with other disorders, such as anxiety disorders. Likewise, to what happens in anxiety disorders, several studies have suggested the presence of dysfunctional body-related Attentional Bias (AB) in patients with ED and, specifically, in AN patients. Patients with AN tend to focus their attention on their body, in a dysfunctional way, by showing body checking behaviors, and scrutinizing their general appearance and weight-related body parts. This body-related AB has been associated with higher levels of body dissatisfaction, one of the most important risk factors for the development and maintenance of ED. In addition, body-related AB may be responsible for decreasing the effectiveness of body exposure-based treatments used in patients with AN. For this reason, it is necessary to develop new treatment techniques by adding specific components that aim to reduce body-related AB. It has been proposed to include AB modification techniques within the body exposure therapy, as an effective treatment to reduce body-related AB, body dissatisfaction, and body anxiety. To date, our group has been the first, to use a combination of virtual reality (VR) and eye-tracking (ET) techniques to assess the presence of a body-related AB in non-clinical samples. In order to improve AN-based treatments, this project aims to develop a new AB modification procedure, using ET and VR technologies. In addition, this project aims to integrate this AB modification procedure as a part of a body exposure-based treatment that aims to reduce the fear of weight gain experienced by patients with AN. Finally, this project aims to assess whether adding two separate components of body exposure-based therapy and AB modification training would result in a more effective intervention. It is expected that adding a specific component of VR body exposure procedure in the usual treatment for AN, enhanced through the illusion of ownership toward the virtual body, will result in more effective treatment. In addition, it is expected that adding an AB modification training in the body-exposure-based procedure, will result in a further increase the effectiveness of the treatment.
The purpose of this study is to determine obsessive-compulsive symptoms and BMI changes in children and adolescents with anorexia nervosa and find out whether there is a group-level correlation between the two. We also investigate a possible link between obsessive compulsive symptoms and the psychological features of eating disorders. It is a national, academic, interventional study. The data will be acquired through questionnaires.
This Open-Label Pilot Study Aims to Determine Whether a Two-Part Sequenced Out Patient Procedure Utilizing a Modified Ketogenic Diet Followed by a Series of Titrated Ketamine Infusions Results in Improvement or Remission of Chronic Anorexia Nervosa in Adults with Symptoms of Anorexia for at Least 3 Years Despite Treatment Involving at Least 2 Different Modalities. The Hypothesis is That the Diet Addresses Core Metabolic Deficits in the "Anorexic Brain" and Primes the Response to Ketamine.
The COVID-19 pandemic has had detrimental effects on mental health. Individuals with eating disorders (EDs) are no exception, exhibiting increased symptoms and exacerbated feelings of isolation and anxiety. Across Canada, in-person outpatient services have been quickly replaced with virtual care, yet practitioners and patients have noted substantial challenges in adapting ED-related care virtually. Given the success of our previous research on Family-Based Treatment (FBT) for EDs, as well as the rapid transition to virtual care during COVID-19, there is an urgent need to adapt FBT to virtual formats and adopt it in the ED network. Using a multi-site case study with a mixed method pre/post design, this study aims to examine the implementation of virtual FBT (vFBT) as well as its impact within six ED programs in Ontario, building on the investigator's previous work, and further developing capacity in the system. The investigator will develop implementation teams at each site and provide a virtual training workshop on vFBT, with ongoing consultation during initial implementation. The investigator proposes to examine implementation success by studying fidelity to vFBT, as well as team and patient/family experience with virtual care, and patient outcomes. These findings for virtual care will not only be important in the COVID-19 context but are also vital in the North, where access to specialized services is extremely limited.
In this study, when patients diagnosed with AN started treatment and their weight increased by 10%; On the other hand, it was aimed to compare the changes in serum adipokine levels observed in morbidly obese patients before bariatric surgery and when they lost 10% of their post-op weight with both anthropometric measurements, biochemical parameters, and values of healthy volunteers.
The primary aim of this study is to assess the safety and tolerability of one 25 mg dose of psilocybin in participants with anorexia nervosa based on adverse events (AEs), changes in vital signs, electrocardiograms (ECGs) and clinical laboratory tests. The secondary objectives are to explore the efficacy of a single 25 mg dose of psilocybin on eating disorder symptoms and behaviors, body image, anxiety, food related obsessions and rituals, and body weight.
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.
The purpose of this study is to explore the experience of adolescents suffering from anorexia nervosa confronted with the prescription of antidepressants
Family based treatment (FBT) is the evidence based treatment for pediatric anorexia nervosa (AN), but 50% of adolescents do not respond and the consequences for non-response are dire (e.g., 11.5% mortality rate). Expressed emotion and parental warmth are significant mechanisms of treatment outcome in adolescents with AN, which are not explicitly targeted by FBT. The current proposal is a parent emotion coaching skills group designed to augment FBT in the treatment of pediatric AN by arming high expressed emotion families with the skills necessary to implement FBT and improve treatment outcomes (e.g., weight restoration).
