34 Clinical Trials for Various Conditions
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.
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 objective of this study is to evaluate the effectiveness of oral naltrexone tablets in pediatric and adolescent eating disorders, in particular anorexia nervosa and bulimia nervosa, as compared to placebo. Study participants will be patients in a partial hospitalization program or intensive outpatient program for eating disorder.
The goals of this project are to 1) develop training opportunities for master's-level and pre-doctoral psychology students in evidence-based assessment and treatment of adolescent EDs; 2) to provide the healthcare workforce, including licensed health professionals such as primary care physicians and behavioral health interventionists, with knowledge and competence to recognize early symptoms of and intervention strategies for EDs; and 3) to test the efficacy of delivering two evidence-based treatments for adolescent eating disorders, Family Based Treatment (FBT) and Enhanced Cognitive Behavioral Therapy (CBT-E), in the home-based setting.
The goal of this clinical trial study is to test the heart rate variability biofeedback training in female college students with eating disorders and compare the results between intervention and control group. The main questions it aims to answer are: * How does heart rate variability biofeedback (HRVB) training impact behaviors related to eating disorders (EDs) and the perceived stress associated with these behaviors? * What difference are observed in the quality of life and stress responses between individuals trained in HRVB protocol and those in the wait list condition? * Does HRVB training enhance heart resilience and improve the ability to cope with psychosocial stressors in young women with eating disorders, compared to those in the wait list condition? Participants will be asked to do the following steps: * Baseline heart rate variability assessment and completion of the baseline questionnaire * HRVB training session and two weeks of at-home HRVB practice-10 minutes daily, (intervention group) * Post-intervention questionnaire completion and heart rate variability assessment * Optional interview (for intervention group) and HRVB training session (for control group) Researchers will compare the results of intervention group with control group to see if the participants improve in levels of emotional health, quality of life, and resilience.
To better define the presence of Barrett's esophagus (BE) via non-endoscopic testing in an eating disorder cohort with purging (vomiting/rumination) behaviors
To determine the accuracy of continuous glucose monitoring (CGM) with point of care (POC) fingerstick glucose monitoring and venous blood glucose in patients with eating disorders, specifically anorexia nervosa, restricting subtype (AN-R); avoidant/restrictive food intake disorder (ARFID); and anorexia nervosa, binge/purge subtype (AN-BP).
The purpose of this study is to investigate areas of the brain responsible for avoidance learning in adults with eating disorders using brain imaging techniques, computer tasks, and self-report questionnaires and interviews. The investigators will study changes in brain activity using a procedure called functional magnetic resonance imaging (fMRI). This study will include 78 women with an eating disorder (26 with anorexia nervosa \[AN\], 26 with bulimia nervosa \[BN\]) and 26 healthy controls (HC) aged 18-39. Aim 1: Evaluate behavioral differences in active and passive avoidance learning in eating disorders and associations with symptoms. Aim 2: Evaluate whether corticostriatal and limbic-prefrontal fMRI BOLD response associated with avoidance learning differs in eating disorders relative to healthy controls and relates to symptoms. Aim 3: Evaluate whether functional connectivity of avoidance learning neural circuity differs in eating disorders relative to healthy controls.
We will evaluate the acceptability and feasibility of a 8-week long digital mindfulness-based intervention for anorexia nervosa and bulimia nervosa. This study is a prospective single-arm trial during the intervention development phase. Following this phase, after the intervention has been further developed, a subsequent study (with a different clinicaltrials.gov identification #) will utilize a randomized control trial design.
The purpose of this study is to investigate areas of the brain responsible for 'liking', 'wanting', and learning in adults with eating disorders using brain imaging techniques, computer tasks, a test meal, and self-report questionnaires and interviews. The investigators will study changes in brain activity using a procedure called functional magnetic resonance imaging (fMRI). This study will include 252 women with an eating disorder (63 AN-restricting type (AN-R), 63 AN-binge eating/purging type (AN-BP), 63 bulimia nervosa (BN)) and 63 healthy controls (HC) aged 18-39. Aim 1: To examine neural differences in 'liking' and 'wanting' in ED relative to HC. Aim 2: To examine differences in instrumental learning for reward and punishment in ED relative to HC. Aim 3: To examine how 'liking' and 'wanting' drive instrumental learning in ED and predict clinical symptoms at baseline and 1 year later. Exploratory Aim: To explore the associations of dopamine function, as measured by neuromelanin MRI (NM-MRI), with ED diagnosis and brain response to 'liking', 'wanting', and learning.
The current study will use a full factorial design to identify the independent and combined effects of four core MABT components when combined with standard behavioral treatment for BN and BED. The primary aim of the study will be to evaluate the independent efficacy of Mindful Awareness, Distress Tolerance, Emotion Modulation, and Values-Based Decision Making on eating pathology (at posttreatment and at 6 and 12-month follow-ups). Secondary aims will be (1) to test target engagement of each MABT component, i.e., to confirm that each treatment component impacts both the variable which it targets and self-regulation and that improvements in these are associated with improvements in outcomes and (2) to test the hypotheses that the efficacy of each component is moderated by related baseline deficits in self-regulation (e.g. individuals with worse distress tolerance at baseline are most likely to benefit from conditions that include the Distress Tolerance component). A final exploratory aim will be to quantify the component interaction effects, which may be partially additive (because components overlap and/or there is diminishing return), fully additive, or synergistic (in that components may partially depend on each other).
The overarching intention of the Eating Disorder Genetics Initiative 2 (EDGI2) is to increase sample size, diversity, and eating disorder phenotypes. The investigators are enrolling 20,000 new participants with anorexia nervosa (AN), bulimia nervosa (BN), binge-eating disorder (BED), avoidant/restrictive food intake disorder (ARFID), and controls in the US, Mexico, Australia, New Zealand, Sweden, and Denmark. A primary study goal is to enroll at least 30% of participants from underrepresented groups. Participants are asked to complete a series of questionnaires and submit a saliva sample for genotyping. The goal is to better understand eating disorders and how they relate to each other so that better treatments can be developed.
Occupational therapy is uniquely poised to help address chronic Eating Disorders (EDs) because of our holistic approach to client care. The complex and serious nature of EDs spans so many areas of life and wellbeing, it requires an intervention strategy that addresses the whole person across mental, physical, social, and spiritual realms. Unfortunately, specialized care for EDs can be difficult to find - especially for those not sick enough to be admitted to an inpatient facility but who are still struggling to thrive in daily life. For example, in New Mexico there is only one inpatient treatment center for EDs and no specialized outpatient services. This leaves many people suffering from EDs without options for care because they are not yet sick enough. There is a need for novel interventions in this setting that go beyond the traditional weight and food-focused medical interventions and seek to help empower individuals, work around challenges, and live their lives to the fullest. To meet this need in our community, the study team is developing a preliminary outpatient treatment program. The ROADE (Restorative Occupational Approaches for Disordered Eating) Program is an 8-week, structured, multimodal intervention seeking to reduce psychosocial symptoms and improve self-management skills for disordered eating. The intervention strategies range from: (1) wellness activities like mindfulness meditation to improve interoception, self-acceptance, and as a self-guided coping tool (2) adaptation of health management and self-care occupations to improve daily functioning while navigating ongoing disordered eating symptoms and (3) light exercise like Yoga and lymphatic drainage exercises to reconnect in a positive way with the body, improve digestion, promote relaxation, and reduce muscle tension. The current research investigates the feasibility and acceptability of this intervention while testing preliminary effects on eating disorder symptoms.
This study will investigate the effects of ketone supplementation on eating behavior including drive to binge eat or restrict, mood and anxiety in individuals with anorexia or bulimia nervosa. In addition, the investigators will contrast the effects of active ketone supplementation versus placebo on electroencephalogram (EEG) measurement. All subjects enrolled in the study will undergo EEG on two consecutive days at the beginning of the study, after active ketone supplementation or placebo drink, matched in taste to the ketone drink. Days will be randomized. Thereafter, all subjects will take the ketone supplementation drink for two weeks, twice daily.
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.
The primary aim of this study is to study how Repetitive Transcranial Magnetic Stimulation (rTMS) tailored to specific anorexia nervosa (AN) or bulimia nervosa (BN) brain activation alterations will promote recovery and to study how inhibitory tDCS (Transcranial Direct Current Stimulation) will reduce symptoms of body image distortion in a second sample of AN and BN groups.
Yoga facilitates the treatment of eating disorders by decreasing symptom severity over time.
The purpose of this research study is to test a new type of counseling developed to decrease symptoms of anorexia nervosa and bulimia nervosa and improve health and well-being in women with these eating disorders. At this time, the most effective form of treatment for anorexia nervosa and bulimia nervosa is cognitive behavioral therapy. However, this form of treatment leads to a complete absence of symptoms in only about 50% of persons completing the treatment program. In this study we will test the effectiveness of a new form of counseling that focuses on identifying and building personal strengths and positive views of the self as the means to decrease eating disorder symptoms and improve health. This study will involve 150 women between the ages of 18 and 35 years who currently have symptoms of anorexia nervosa or bulimia nervosa. To participate in this study, women must also be: 1) not pregnant, 2) without any other diagnosable mental disorder, 3) not currently taking medications for their eating disorder or other mental disorder symptoms, 4) not ill enough to require inpatient treatment for their eating disorder and 5) willing to refrain from seeking other treatment for their eating disorder for the duration of this study. Each participant will participate in a 20-week treatment program that includes nutritional counseling and medical care. Both of these forms of treatment are considered by the American Psychiatric Association to be essential parts of treatment for eating disorders and have been found help to reduce symptoms. In addition, participants will receive one of two types of counseling: 1. Experimental counseling that focuses on building strengths and positive self-views 2. Standard counseling that helps the participant identify and solve problems that are believed to contribute to their eating disorder symptoms. The type of counseling that a participant receives will be determined randomly. To determine whether the experimental counseling is effective, eating disorder symptoms, psychological and functional health will be measured before the treatment begins and three times after the treatment ends (immediately after treatment ends, 6 and 12 months later). The findings of this research study are expected to contribute to the development of effective interventions to decrease eating disorder symptoms, and increase health and well-being in women with anorexia nervosa and bulimia nervosa.
A technique that has been found to be effective at relieving the physical and psychological symptoms associated with inhibiting emotions and emotional thoughts is written emotional disclosure. The goal of this study is to evaluate the effectiveness of written emotional disclosure on the remediation of eating disorder behaviour, cognitions, and management of emotions.
Social processing and cognition are often altered in patients with eating disorders. The goal of this clinical trial is to assess two different social therapeutic interventions -- one educational, one interactive -- for their effectiveness in improving clinical outcomes in patients with eating disorders. Patients in both interventions will receive education about social function in eating disorders, but those in the interactive treatment group will complete an additional collaborative art task. Participants will: * attend a baseline study visit to complete clinical interviews, cognitive testing, and behavioral tasks * complete a pre-intervention assessment with questionnaires * attend eight sessions of their assigned treatment group over the course of 12 weeks * complete three virtual follow-up assessments 4, 8, and 12 months from their baseline * attend a final study visit to repeat some clinical interviews, cognitive testing, and behavioral tasks Researchers will compare changes in eating disorder, mood, and anxiety symptoms as well as test results from baseline and final study visits for each group to see if * patients can be treated effectively with education alone or if an interactive group component produces additional benefits * cognitive and behavioral task performance are associated with recovery or illness state.
Using a randomized, placebo-controlled, crossover study, this study will evaluate functional magnetic resonance imaging (fMRI) as a pharmacodynamic biomarker of opioid antagonism in adolescents with eating disorders. The hypothesis is that fMRI will be able to detect acute reward pathway modulation by naltrexone (an opioid antagonist) in pre-defined regions of interest (anterior cingulate cortex, nucleus accumbens, dorsolateral prefrontal cortex).
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.
The purpose of this study is to collect preliminary data on the feasibility and acceptability of the randomization of two relapse-prevention treatment conditions after discharge from intensive eating disorder (ED) treatment: an imaginal exposure therapy and a writing and thinking intervention. The second aim to test for (a) differences between the two treatments for the prevention of relapse and (b) preliminary change on clinical ED outcomes (e.g., ED symptoms, fears). The investigators further aim to examine the two treatments target fear extinction and if fear extinction is associated with ED outcomes. The investigators also plan to test if baseline differences in fear conditioning relate to change in ED outcomes across treatment.
The purpose of this study is to test if imaginal exposure therapy can decrease symptoms of eating disorders and anxiety.
This study evaluates if imaginal exposure therapy can decrease symptoms of eating disorders and anxiety, and test an online format of IE to maximize its ability to reach as many individuals with eating disorders as possible. All participants will complete four imaginal exposure sessions and will complete questionnaires prior to receiving this treatment, as well as complete follow up questionnaires at 1-month, 6-month, and 12-month.
The goal of the study is to evaluate two 6-month adjunct interventions (peer mentorship and social support mentorship) for individuals with eating disorders. Individuals will be randomized to peer-mentorship, social support mentorship, or a wait-list and eating disorder symptoms will be evaluated at baseline and post-treatment.
Eating disorders (EDs) are serious mental illness: someone dies of an ED every 52 minutes. EDs are highly related to a host of negative outcomes, including public health and individual disease burden, medical and psychological comorbidities, and social determinants of health (SDOH). Treatment response for EDs are suboptimal; there are no evidence-based treatment for adults with anorexia nervosa (AN) or Other Specified Feeding or Eating Disorder (OSFED) and only 50% of adults respond to current evidence based treatments. There are no precision treatments, nor any treatments that consider social context, in existence. Personalized treatments for EDs, that consider social contexts, are urgently needed to improve treatment response and minimize the suffering associated with these illnesses. The investigators' overall goal, extending upon their past work, is to create a treatment personalized based on idiographic (or one person) models (termed Transdiagnostic Network Informed Personalized Treatment for EDs; T-NIPT-ED). The investigators will carry out a two-phase study to systematically characterize individual mechanisms of treatment (Phase I: N=900) and then test the efficacy of each treatment module (Phase II: N=240 drawn from Phase I) compared to the current gold-standard treatment (Cognitive Behavioral Therapy Enhanced: CBT-E). The study goals are to (1) characterize the prevalence of T-NIPT-ED precision treatment mechanisms and medical and psychological comorbidities (e.g., obesity; depression), individual disease burden (e.g., disability), SDOH (e.g., food insecurity), and public health outcomes (e.g., service utilization) specific to these mechanisms, (2) identify if personalized target mechanisms improve when matched to evidence-based treatment modules of T-NIPT-ED and (3) test if change in T-NIPT-ED is associated with improved outcomes (vs CBT-E), including ED outcomes, comorbidities, disease burden, and public health outcomes and if these outcomes are moderated by SDOH. These goals will ultimately lead to the very first precision treatment for ED and can be extended to additional psychiatric illnesses. The proposed research uses highly innovative methods; intensive longitudinal data collected with mobile technology is combined with state-of-the art idiographic modeling methods to deliver a virtual, personalized treatment. This proposal integrates assessment of broad (e.g., SDOH; public health burden) and specific (e.g., ED symptoms) outcomes, to ensure that social context can be integrated into personalization. The proposed research has high clinical impact. Ultimately, this proposal will lead directly to the creation and dissemination of an evidence-based individually-personalized treatment for EDs, as well as will serve as an exemplar for precision treatment development across the entire field of psychiatry.
The investigators plan to collect preliminary data on the feasibility, acceptability, and user uptake of a personalized self-guided mobile intervention for disordered eating (DE) and test the initial clinical efficacy of this intervention. Women (N=50) who endorse significant DE will complete two weeks of smart-phone self-monitoring to identify target problems and will be sent two self-guided modules of personalized treatment directly to their smart-phones. The investigators will assess engagement with the modules throughout two months and administer baseline, week 5, and week 8 assessments for acceptability, uptake, and initial clinical efficacy (e.g., DE symptoms, anxiety, quality of life). The investigators will also complete a focus group (n=10) with a subset of users to receive input on the mobile-application assessment and ease of self-guided intervention modules.
The scientific premise, developed from past work, is that treatment personalized based on idiographic models (termed Network Informed Personalized Treatment; NA-PT) will outperform the current gold-standard treatment (Enhanced Cognitive Behavioral Therapy: CBT-E). The study goals are to (1) develop and test the acceptability, feasibility, and preliminary efficacy of a randomization of NA-PT versus CBT-E and (2) to test if network-identified precision targets are the mechanism of change. These goals will ultimately lead to the very first personalized treatment for ED and can be extended to additional psychiatric illnesses. Specific aims are (1) To collect preliminary data on the feasibility and acceptability of the randomization of NA-PT (n=40) for EDs versus CBT-E (n=40), (2) To test the initial clinical efficacy of NA-PT versus CBT-E on clinical outcomes (e.g., ED symptoms, body mass index, quality of life) and (3) To examine if changes in NA-identified, precision targets, as well as in dynamic network structure, are associated with change in clinical outcomes.
This pilot study will assess the effectiveness of an original oral health education program on affecting the behaviors of patients diagnosed with eating disorders.
