How Eating Disorder Tests Work

The National Eating Disorder Association (NEDA) report that 20 million women and 10 million men suffer from a clinically significant eating disorder at some point in their lives.1 Eating disorders are serious, potentially life-threatening conditions that impact physical and emotional health.

There are many different types of eating disorders, and no single test can diagnose all of them. However, there are certain tests and screenings that can help identify whether someone is at risk for an eating disorder or is currently struggling with one.

Screenings for eating disorders often look for signs and symptoms of an eating disorder, such as extreme preoccupation with food and weight, an avoidance of eating, rapid weight loss or gain, and an intense fear of gaining weight.2

Some common tests used to screen for eating disorders include the following:

The Body Mass Index (BMI) is a measure of body fat based on height and weight. A BMI of 30 or higher is considered obese, while a BMI of 25 to 29.9 is considered overweight. A BMI below 18.5 is considered underweight.3

The BMI is not a perfect measure, as it does not take into account factors such as muscle mass, and it can be misleading for people who are very tall or very short. However, it is a quick and easy way to get an idea of whether someone is at a healthy weight.

The Eating Disorder Inventory (EDI) is a self-report questionnaire that assesses symptoms of anorexia nervosa, bulimia nervosa, and binge eating disorder.4 The EDI is not a diagnostic tool, but it can help give a general idea of whether someone is struggling with an eating disorder.

The Three-Factor Eating Questionnaire (TFEQ) is another self-report questionnaire that assesses symptoms of binge eating disorder.5 The TFEQ can also help give an idea of whether someone is struggling with an eating disorder.

The Minnesota Starvation Experiment was a study conducted in the 1940s in which participants underwent a six-month period of calorie restriction.6 The study was designed to understand the psychological and physical effects of starvation, but it also provided insight into the development of eating disorders.

The participants in the study were put into two groups: a control group and a experimental group. The experimental group was given a diet of 1,560 calories per day, while the control group was given a diet of 3,200 calories per day.

Both groups lost weight, but the experimental group experienced more severe psychological and physical effects, such as hair loss, skin rashes, and problems with concentration. The study showed that restrictive diets can lead to disordered eating behaviors.

The Yale Food Preferences Questionnaire (FPQ) is a self-report questionnaire that assesses an individual’s food preferences.7 The FPQ can help give an idea of whether someone is at risk for developing an eating disorder, as it can identify individuals who have an aversion to certain foods or groups of foods.

The Eating Disorder Examination (EDE) is a structured interview that assesses symptoms of anorexia nervosa, bulimia nervosa, and binge eating disorder.8 The EDE is considered the gold standard for eating disorder assessments, as it is more comprehensive than self-report measures.

The EDE can be used to make a diagnosis of an eating disorder, but it is also useful for identifying risk factors and early signs of an eating disorder.

The Eating Disorder Examination-Questionnaire (EDE-Q) is a self-report version of the EDE.9 The EDE-Q can be used to screen for eating disorders, but it is not as comprehensive as the EDE.

The diagnostic criteria for eating disorders are listed in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5).10 To be diagnosed with an eating disorder, an individual must meet certain criteria, such as having a preoccupation with food and weight, engaging in restrictive eating behaviors, and experiencing negative effects on their physical and emotional health.

The DSM-5 also provides guidelines on how to diagnose subclinical eating disorders, such as binge eating disorder not otherwise specified (BEDNOS).11 BEDNOS is similar to binge eating disorder, but the individual does not meet the full criteria for the disorder.

There is no one perfect test for diagnosing eating disorders. However, there are several tools that can be used to screen for eating disorders and assess an individual’s risk..Click here for info

The Limitations of Eating Disorder Tests

A lot of people think that they can just go online and take an eating disorder test in order to determine whether or not they have an eating disorder. Unfortunately, this is not the case. While there are some online tests that can give you a general idea of whether or not you may have an eating disorder, they are not 100% accurate. Here are some of the limitations of eating disorder tests:

1. They are not anonymous.

If you take an online test, chances are your name and email address will be required. This means that your results are not truly anonymous, and you may not be comfortable sharing your results with anyone.

2. They are not always accurate.

Like we said before, online tests are not always accurate. This is because they are not always created by professionals, and they do not always consider all of the factors that could contribute to an eating disorder.

3. They can be triggering.

If you are struggling with an eating disorder, taking an online test can be triggering. This is because the questions on the test can remind you of your eating disorder and can make you feel worse about yourself.

4. They can be time-consuming.

Some online tests can be quite long, and they can take a lot of time to complete. If you are already struggling with an eating disorder, you may not have the time or energy to complete a long test.

5. They can be expensive.

While there are some free online tests, many of them come with a fee. If you are struggling to pay for food or treatment, you may not be able to afford to take an online test.

While online eating disorder tests can be helpful, they have many limitations. If you are concerned that you may have an eating disorder, it is important to speak to a professional who can give you a proper diagnosis.
