Eating Disorder Research, Studies, and Tests

To help further the treatment of eating disorders, Eating Disorder Hope maintains this list of tests, studies, questionnaires, and examinations that are looking for volunteers, and/or offer free evaluation. These tests and professional studies are making every-day differences in helping us to understand the causes of and best treatment practices for eating disorders.


Screening Methods and Tests

Eating Attitudes Test (EAT-26)

The EAT-26 is the most widely cited standardized self-report screening measure that may be able to help you determine if you have an eating disorder that needs professional attention. The EAT-26 is not designed to make a diagnosis of an eating disorder or to take the place of a professional diagnosis or consultation.  The EAT-26 is free to users (  Take the EAT-26 now and get immediate and anonymous feedback:

Eating Disorder Inventory-3 (EDI-3)Eating Disorder Inventory-3

The Eating Disorder Inventory-3 (EDI-3) is a revision of the most widely used self-report measure of psychological traits or constructs shown to be clinically relevant in individuals suffering from eating disorders (Garner, 2004).  The EDI-3 is a standardized and easily administered measure yielding objective scores and profiles that are useful in case conceptualization and treatment planning for individuals with a confirmed or suspected eating disorder.  It is also a valuable research tool for assessing areas of psychopathology of interest in theory-testing, identifying meaningful patient subgroups and assessing treatment outcome. The EDI-3 and the EDI-3 Referral Form (for screening) can be ordered from Psychological Assessment Resources:

Scientific Exploration of Eating Disorders

The field of eating disorder research is continually evolving, and treatments are being developed and refined based on these discoveries. Given the complex nature of eating disorders, it is not surprising that the factors that contribute to these diseases are multifaceted.  There is not one single cause responsible for the formation and development of an eating disorder, but rather, an accumulation of several possible compounding factors that each play a role in the development and maintenance of these diseases.  These factors can be biological, sociological, emotional, environmental, etc.

One factor frequently investigated by researchers is the biological component of eating disorders.  Many have pondered and theorized what mechanisms occur in the human body, and brain specifically, that can make an individual susceptible to developing anorexia, bulimia or binge eating disorder.  Studies are currently underway that are examining potential contributing factors of an eating disorder, such as genetics, hormones, and neurobiology. Read this article to learn more about Scientific Developments and Research in Eating Disorders.


Research & Studies

Stanford University Research Study

Project Name: Qsymia (phentermine-topiramate) to Reduce Binge Eating/Purging in Patients with Binge Eating Disorder and Bulimia Nervosa

Project Description: This study aims to test the efficacy of an FDA approved drug for obesity, Qsymia, for reducing symptoms of binge eating and/or purging in participants with binge eating disorder and bulimia nervosa, compared to a control medication. All study participants will receive the study medication– either in the first half of the study or in the second half of the study. Neither you nor members of the research team will know the order in which you receive them until the end of the trial. Medication is provided at no cost and the study is expected to take up to 6 months.

Stanford Research Study ImageWho can participate? Men and women aged 18-60 with current symptoms of binge eating and/or purging

University of California San Diego’s Eating Disorders Center for Treatment & Research seeks female volunteers for research studies

We are currently recruiting for three studies utilizing a technology called magnetic resonance imaging (MRI). MRI techniques use powerful magnetic fields that temporarily magnetize some of the chemicals in your brain, which allows a scanner and a computer to take a very detailed picture of the structure of your brain.

  • Project Name: Neurobiology of Anorexia and Bulimia. Project Description: This study is designed to assess brain response to different types of sensation. You would be compensated $200 for this single visit. We are recruiting women between the ages of 18 -45. We require that our participants be drug and medicine free for at least 3 months (birth control is okay), as well as be behavior/symptom free for at least 12 months, if you have recovered from an eating disorder.
  • Project Name: Neurobiology of Reward and Decision-Making in Bulimia Nervosa. Project Description: This MRI study is also a one-hour scan session for which participants will be compensated up to $200 for taking part. We are recruiting women between 15 and 30 years old. Participants must be drug and medicine free for at least 3 months (birth control is okay). Participants may currently have or be recovered (behavior/symptom free for at least 12 months) from bulimia nervosa, or may have never had an eating disorder.
  • Project Name: Neural Bases of Multiple Forms of Self-Regulatory Control in Bulimia Nervosa. Project Description: This third MRI study requires three hours of interview and assessment time with a one-hour scan session for which participants will be compensated up to $200 for taking part. We are recruiting women between 15 and 35 years old. Participants must be drug and medicine free for at least 3 months (birth control is okay). Participants may currently have bulimia nervosa and engage in purging behaviors, or may have never had an eating disorder.

The Chicago School of Professional Psychology seeks female volunteers for study

Project Name: Adolescent’s Experience of Anorexia with a Friend; A Phenomenological Study

Project Description: Various research has suggested that adolescent female friends share similar attitudes and behaviors toward body image concerns and dieting.  While the importance and influence of friends has been examined, one area that lacks research and understanding is the role that a friend who has previously suffered from anorexia plays in a friend’s current experience with anorexia.  The proposed research aims to eliminate this gap in understanding through a phenomenological study involving in-depth interviews with six females who suffered from anorexia nervosa during adolescence.

Seeking females 18+ who have recovered from anorexia nervosa within the past five years. Specifically seeking those who had a friend who also struggled with anorexia nervosa during or prior to the friendship.

Researchers from Deakin University, School of Psychology Seek Volunteers for Eating Disorder Study

Project Name: Profiling the early maladpative schemas, schema modes, and eating disorder behaviors in eating disorder subgroups.

Project Description: Eating disorders (EDs) are associated with severe psychological and physiological impacts. ED affected individuals often hold chronic and rigid beliefs and tend not to respond to standard psychological treatments, suggesting a more focused, sophisticated and intensive treatment approach such as Schema Therapy and Schema Mode therapy might be needed.

The aim of this study is to profile the patterns of specific Early Maladaptive Schemas (EMSs) and Schema Modes (SMs) in ED groups. EMSs are one’s unhelpful beliefs about themselves, others, and the world around them. These beliefs are developed in childhood and adolescence and built upon throughout one’s life. SMs are a combination of these schemas and coping behaviors that are either adaptive or maladaptive and present at any particular moment. Gaining insight into the underlying belief system can be critical in the ongoing optimization of clinical assessment and treatment of EDs.

Researcher from The City University London, School of Social Sciences, Seeking Volunteers

Project name: Feelings and Faces

Purpose of Study: Researchers are looking at the reasons why some people have difficulties with impulsive behaviours, such as self-harm and what their feelings are around food. This study aims to look at how people pick up on what others are thinking and feeling, as well as how people think about their own thoughts and feelings. Greater knowledge in this area will help in designing better psychological therapies for people who have impulsive behaviours or strong feelings they find it difficult to deal with.

If you suffer from an eating disorder with/without self-harm and are interested in participating in a research study about feelings & faces, please access survey here.

This research has been approved by City University and the NHS. If you would like to ask more questions about the research, please contact Angie Cucchi on 07930 645428  or email:

Dyadic Adjustment in Mothers of Children with Anorexia

Are you the mother of a child who is currently receiving outpatient treatment for Anorexia Nervosa? If so, we’d like to invite you to participate in an anonymous study that examines the experience of caring for a child with Anorexia Nervosa. This study will look at how a child’s eating disorder affects the parents and family, and how families cope with caring for a child with Anorexia. We hope these research findings will provide greater insight into how a child’s illness affects families, so that more support services can be developed to help parents and caregivers. To be eligible for this study, you must be the mother to a child with Anorexia and currently be in a committed relationship. If your child is between the ages of 10-21, is currently receiving outpatient treatment for Anorexia Nervosa, and is currently living with you and your spouse/partner at home, we invite you to participate in this important study.Participation will involve: Completing the questionnaire online will take approximately 15-30 minutes. You will not be asked to provide your name at any time– Publications or presentations about the research findings will not include individual responses, only summary data on all participants will be presented.

5Department of Global Health & Social Medicine, Harvard Medical School, Boston, MA, USA

Objective: The DSM-5 Eating Disorders (ED) Work Group has proposed new diagnostic criteria that broaden anorexia nervosa (AN) and bulimia nervosa (BN); add new disorders (e.g., binge eating disorder, avoidant/restrictive food intake disorder); and create descriptive subtypes within ED not otherwise specified (EDNOS). However, the reliability and validity of these new criteria have not been prospectively tested. The purpose of this study was to evaluate the clinical utility of proposed DSM-5 criteria by assessing the prevalence of EDNOS under DSM-IV versus DSM-5; and the inter-rater reliability of research and clinician diagnoses in DSM-IV versus DSM-5.

Method: Consecutive female patients aged 13-23 (N = 42) admitted to a residential ED treatment facility received both DSM-IV and DSM-5 ED diagnoses from a research assessor (n = 3) via the Eating Disorder Examination; and a treating clinician (n = 13) via an unstructured interview in routine care. We tested our hypothesis that significantly fewer patients would receive EDNOS diagnoses under DSM-5 versus DSM-IV using Fisher’s exact test, and evaluated inter-rater reliability between research and clinician diagnoses using Cohen’s kappa.

Results: As hypothesized, significantly fewer patients received EDNOS diagnoses from researchers under DSM-5 (n = 14; 33%) versus DSM-IV (n = 30; 71%), p = .003. Clinicians also conferred fewer EDNOS diagnoses under DSM-5 (n = 7; 17%) than DSM-IV (n = 14; 33%), p = .003. While research and clinical diagnoses showed moderate inter-rater reliability under DSM-IV (κ = .41), they showed substantial reliability under DSM-5 (κ = .62).

Conclusion: Our preliminary data suggest that the proposed DSM-5 revisions will successfully reduce the predominance of EDNOS in this naturalistic clinical setting. Importantly, the observed improvement in clinical utility is not associated with a reduction in inter-rater reliability, suggesting that clinicians can reliably apply the new criteria in routine care.
