Brief Description of the Tool The Eating Disorders Examination Questionnaire (EDE-Q; Fairburn &

Eating disorders are common, relatively chronic and potentially life-threatening psychiatric disorders conditions primarily affecting young women. Eating disorders are also associated with psychological suffering, acute and long-term health impairments, a high rate of suicide attempts as well as an increased risk of mortality early detection and treatment improve the prognosis, but the presentation of eating disorders is often cryptic. This paper will compare the constructs of two assessment tools and examine the key test measurement constructs of reliability and validity for each assessment tool use in eating disorders. The Eating Disorder Inventory-3 (EDI-3) and the “Eating Disorder Examination-Questionnaire (EDE-Q)” acre commonly used assessments

Several assessment tools have been developed to assess symptoms and behaviors of different constructs including: eating disorders, anxiety, depression, personality, obsessiveness, among others. A common assessment tool in the assessment of symptoms and other features of eating disorders is the Eating Disorder Inventory (EDI) that was originally developed by Garner, Olmsted, and Polivy in 1983. Another widely used eating disorder assessment tool is the Eating Attitudes Test (EAT) that was developed by Garner and Garfinkel (1979). While both are self-report measures of symptoms of eating disorders and are available in revised forms (EDI-3 and EAT-26), they differ in their reliability and validity as well

The Eating Attitude Test yields the overall score and has three subscales that can help determine some specifics. The overall score has a cutoff of 20, and those who score less than 20 are considered as not having an eating disorder, while those who score 20 and more will have to be evaluated by the follow-up assessment tool (Garner & Garfinkel, 1979). The subscales reveal information about bulimia, food preoccupation, dieting and oral control subscales.

This article explored the topic of identifying symptoms in patients with anorexia nervosa (AN). The Eating Disorder Inventory led a study, conducted by D. Garner, that studied females with AN to classify behavior exclusive to the psychological disorder. The researchers recognized the problem of trying to identify any restrictive manners or detrimental behaviors that could identify a person with AN. The purpose of the research was to find tell-tale symptoms or psychological indicators of AN in patients.

The (EDI) is used in “clinical setting to obtain cognitive, behavioral, and affective or emotional profiles of individuals with eating disorders (anorexia nervosa)” (p44). The Obligatory Exercise Questionnaire (OEQ) is also used it is a questionnaire that was developed to measure levels of obligatory exercise (p44). The study consisted of “one thousand second and third year students who were randomly selected from the Faculty of Education Services” (Matheson & Crawford-Wright 2000). The (OEQ) consist of 20 questions “scored on a Likert scale ranging from 1=never to 4=” (p44). If the participants “score 50 or greater it indicates exercise dependency” (p44). According to (Matheson & Crawford-Wright 2000) usual questions are:

Anorexia nervosa is an eating disorder that consists of self-regulated food restriction in which the person strives for thinness and also involves distortion of the way the person sees his or her own body. An anorexic person weighs less than 85% of their ideal body weight. The prevalence of eating disorders is between .5-1% of women aged 15-40 and about 1/20 of this number occurs in men. Anorexia affects all aspects of an affected person's life including emotional health, physical health, and relationships with others (Shekter-Wolfson et al 5-6). A study completed in 1996 showed that anorexics also tend to possess traits that are obsessive in nature and carry heavy emotional

Not only is there the idea that there is a pattern, but also that other disordered eating's have had their criteria to be discussed. The first commonly thought of is anorexia nervosa. Common between anorexia and orthorexia is OCD. In which case OCD is the need to control and the sense of perfectionism. Both of these disordered eating's want to perfected some aspect of their food intake and the quality of food that they consume. A prevalence in anorexia nervosa is 0.9% in women and 0.3% in men (Dell’Osso et al., 2016). Similarly like anorexia, bulimia is also a well-known disordered eating's. As of 2000, bulimia incidence rate remained stable for the ages 10-19 years-old for females in the UK at 40 per 100,000 person-years (Smink et al, 2012). The good news is that bulimia nervosa is slowing decreasing over time. This could be in part do to the ability to comprehend and discuss what is considered bulimia. Another disordered eating that has been changed since first establish is Avoidant and Restrive Food Intake Disorder. Formerly known as selective eating it was often referred mostly to young children. ARFID is a problem with eating and/or feeding. This can lead to nutritional deficiency and the lack of energy (Nicely et al, 2014). Such things that people who develop orthorexia could develop. Orthorexia is also similar to that EDNOS. EDNOS stands for eating disorder not otherwise specified and is heterogenous (Smink et al, 2012). Thus, this result implicates that neither females or males stands out above one another just like orthorexia. There has been studies done to find prevalence in gender, but results vary from study to study. EDNOS is very commonly given to someone who has an eating disorder. The disadvantage of this type of disordered eating's is because if can lead to other miss diagnoses and the difficulty for obtaining appropriate treatment (Nicely et al,

In order to prevent a type 1 error, scores for the eating disorder examination were given to readers in the form of effect sizes. The four measured variables were binge eating rates, eating disorder psychopathology, quality of life, and emotional regulation. In comparison to the wait list group, each variable showed improvement, meaning that the treatment (DBT) had a positive impact on the participants assigned to that condition. Over time, there was an effect found for each variable. Using post hoc tests, researchers noticed that binge eating frequency was lower at post-treatment than baseline, the total eating disorder examination (EDE) scores were lower at post-treatment and 6 month follow up compared to baseline, quality of life scores were higher at post-treatment and baseline, and emotional regulation scores were higher at

This construct is evaluated by 4 items using a 5-point Likert-type scale ranking responses from “not at all” (1) to “a lot” (5).

In this step, the difficulty, discrimination, and reliability values of each selected item will be assessed. IRT approach has two main assumptions; unidimensionality and local independence. Unidimensionality refers to that “the items are only refer to one latent variable”, while local independence refers to that “the responses to an item are independent to the responses of any other item” [49].

To test the reliability of the GRCS, Cronbach’s alpha analysis was utilized. For the scale, Cronbach’s alpha was high (alpha =.93) (Raylu, et al., 2003). In this study, test-retest reliability was not evaluated since it was a cross-sectional test; therefore, future studies need to be aware of changes over time that the scale might

In addition, patients with eating disorders also exhibit other traits associated with low self-esteem, such as problems with their overall self-image, excessive concern over weight and shape, and globally negative attitudes about their self-control and discipline (Button 1997). The methodology for the research leading to these conclusions about low self-esteem and eating disorders typically involves elements such as questionnaires examining eating behavior, self-esteem and general psychological well-being (such as the Offer self-image questionnaire), depression and self-esteem scales (such as the Rosenberg self-esteem scale and the Hospital anxiety and depression scale), personal interviews with doctors, psychologists and researchers, and finally tests designed specifically for eating disorders (such as the Bulimia test and the EAT-40).
