Anorectic Behavior Observation Scale
The Anorectic Behavior Observation Scale (ABOS) is a thirty-item diagnostic questionnaire devised to be answered by the parents, spouse or other family member of an individual suspected of having an eating disorder. It was developed by Vandereyken ''et al.'' in 1992. The ABOS is useful for evaluations of patients with anorexia nervosa (AN) and bulimia nervosa (BN) before, during, and after clinical treatments. It can also be a significant tool for the screening of subjects in early-stage ED. The validity and reliability of the ABOS have been confirmed by Vandereycken, and the scale shows good internal consistency with Cronbach's α of .81. Background Gathering data from parents and caregivers is extremely important because patients with ED often tend to deny or minimize their disorder. The early stage of ED is often not immediately identifiable by the relatives, as the first signals can be misinterpreted as a form of self-control or willpower. People with ED, indeed, tend to a ...

Anorexia Nervosa
Anorexia nervosa, often referred to simply as anorexia, is an eating disorder characterized by low weight, food restriction, body image disturbance, fear of gaining weight, and an overpowering desire to be thin. ''Anorexia'' is a term of Greek origin: ''an-'' (ἀν-, prefix denoting negation) and ''orexis'' (ὄρεξις, "appetite"), translating literally to "a loss of appetite"; the adjective ''nervosa'' indicating the functional and non-organic nature of the disorder. ''Anorexia nervosa'' was coined by Gull in 1873 but, despite literal translation, the feeling of hunger is frequently present and the pathological control of this instinct is a source of satisfaction for the patients. Individuals with anorexia nervosa have a fear of being overweight or being seen as such, although they are in fact underweight. The DSM-5 describes this perceptual symptom as "disturbance in the way in which one's body weight or shape is experienced". In research and clinical settings, thi ...

Confirmatory Factor Analysis
In statistics, confirmatory factor analysis (CFA) is a special form of factor analysis, most commonly used in social science research.Kline, R. B. (2010). ''Principles and practice of structural equation modeling (3rd ed.).'' New York, New York: Guilford Press. It is used to test whether measures of a construct are consistent with a researcher's understanding of the nature of that construct (or factor). As such, the objective of confirmatory factor analysis is to test whether the data fit a hypothesized measurement model. This hypothesized model is based on theory and/or previous analytic research. CFA was first developed by Jöreskog (1969) and has built upon and replaced older methods of analyzing construct validity such as the MTMM Matrix as described in Campbell & Fiske (1959). In confirmatory factor analysis, the researcher first develops a hypothesis about what factors they believe are underlying the measures used (e.g., " Depression" being the factor underlying the Beck Dep ...

Eating Disorder Inventory
The Eating Disorder Inventory (EDI) is a self-report questionnaire used to assess the presence of eating disorders, (a) anorexia nervosa both restricting and binge-eating/purging type; (b) bulimia nervosa; and (c) eating disorder not otherwise specified including binge eating disorder. The original questionnaire consisted of 64 questions, divided into eight subscales. It was created in 1984 by David M. Garner and others. There have been two subsequent revisions by Garner: the Eating Disorder Inventory-2 (EDI-2) and the Eating Disorder Inventory-3 (EDI-3). Diagnostic use The Eating Disorder Inventory is a diagnostic tool designed for use in a clinical setting to assess the presence of an eating disorder. It is generally used in conjunction with other psychological tests such as the Beck Depression Inventory. Depression has been shown to yield higher scores on the EDI-3.

Eating Attitudes Test
The Eating Attitudes Test (EAT, EAT-26), created by David Garner, is a widely used 26-item, standardized self-reported questionnaire of symptoms and concerns characteristic of eating disorders. The EAT is useful in assessing "eating disorder risk" in high school, college and other special risk samples such as athletes. EAT has been extremely effective in screening for anorexia nervosa in many populations. The EAT-26 can be used in non-clinical as well as clinical settings not specifically focused on eating disorders. It can be administered in group or individual settings by mental health professionals, school counselors, coaches, camp counselors, and others with interest in gathering information to determine if an individual should be referred to a specialist for evaluation for an eating disorder. It is ideally suited for school settings, athletic programs, fitness centers, infertility clinics, pediatric practices, general practice settings, and outpatient psychiatric departments ...

Diagnostic Classification And Rating Scales Used In Psychiatry
Diagnosis is the identification of the nature and cause of a certain phenomenon. Diagnosis is used in many different disciplines, with variations in the use of logic, analytics, and experience, to determine " cause and effect". In systems engineering and computer science, it is typically used to determine the causes of symptoms, mitigations, and solutions.

Body Attitudes Questionnaire
The Ben-Tovim Walker Body Attitudes Questionnaire (BAQ) is a 44 item self-report questionnaire divided into six subscales that measures a woman's attitude towards her own body. The BAQ is used in the assessment of eating disorders. It was devised by D.I. Ben-Tovim and M.K. Walker in 1991. Sub-scales The six subscales measured by the BAQ are: # Overall fatness # Self disparagement # Strength # Salience of weight # Feelings of attractiveness # Consciousness of lower body fat Foreign-language versions Portuguese version The BAQ was the first body attitudes scale to be translated into Portuguese. The validity of the Portuguese language version was proven in a test conducted on a cohort of Brazilian women who speak Portuguese as their native language. The test-retest reliability was 0.57 and 0.85 after a one-month interval. The test was conducted by Scagliusi ''et al.'' Japanese version The BAQ was translated into Japanese and tested on 68 males and 139 females in Japan and 68 Japanes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Body Attitudes Test
The Body Attitudes Test (BAT) was developed by Probst ''et al.'' in 1995. It was designed for the assessment of multiple eating disorders in women. The BAT measures an individual's subjective body experience and attitudes towards one's own body. It is a questionnaire composed of twenty items which yields four different factors that evaluate the internal view of the patient's own body. Purpose The BAT is used to evaluate self-reported outlooks women with eating disorders have pre-, during, and post-treatment. It has been proven to highlight the psychological changes experienced throughout the rehabilitation process and is a useful way to gauge adherence and success of treatment. This test also has the ability to differentiated between clinical and non-clinical subjects and between anorexics and bulimics. Studies have shown that patients with restrictive anorexia have lower BAT scores, whereas patients with bulimia nervosa score higher. History Michel Probst and colleagues bega ...

Binge Eating Scale
The Binge Eating Scale is a sixteen item questionnaire used to assess the presence of binge eating behavior indicative of an eating disorder. It was devised by J. Gormally ''et al.'' in 1982 specifically for use with obese individuals. The questions are based upon both behavioral characteristics (e.g., amount of food consumed) and the emotional, cognitive response, guilt or shame. {{cite journal , last1 = Celio , first1 = AA , last2 = Wilfley , first2 = DE , last3 = Crow , first3 = SJ , last4 = Mitchell , first4 = J , last5 = Walsh , first5 = BT , title = A comparison of the binge eating scale, questionnaire for eating and weight patterns-revised, and eating disorder examination questionnaire with instructions with the eating disorder examination in the assessment of binge eating disorder and its symptoms , journal = The International Journal of Eating Disorders , volume = 36 , issue = 4 , pages = 434–44 , year = 2004 , pmid = 15558644 , doi = 10.1002/eat.20057 ...

Scree Plot
In multivariate statistics, a scree plot is a line plot of the eigenvalues of factors or principal components in an analysis. The scree plot is used to determine the number of factors to retain in an exploratory factor analysis (FA) or principal components to keep in a principal component analysis (PCA). The procedure of finding statistically significant factors or components using a scree plot is also known as a scree test. Raymond B. Cattell introduced the scree plot in 1966. A scree plot always displays the eigenvalues in a downward curve, ordering the eigenvalues from largest to smallest. According to the scree test, the "elbow" of the graph where the eigenvalues seem to level off is found and factors or components to the left of this point should be retained as significant. Etymology The scree plot is named after the elbow's resemblance to a scree in nature. Criticism This test is sometimes criticized for its subjectivity. Scree plots can have multiple "elbows" that make ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internal Consistency
In statistics and research, internal consistency is typically a measure based on the correlations between different items on the same test (or the same subscale on a larger test). It measures whether several items that propose to measure the same general construct produce similar scores. For example, if a respondent expressed agreement with the statements "I like to ride bicycles" and "I've enjoyed riding bicycles in the past", and disagreement with the statement "I hate bicycles", this would be indicative of good internal consistency of the test. Cronbach's alpha Internal consistency is usually measured with Cronbach's alpha, a statistic calculated from the pairwise correlations between items. Internal consistency ranges between negative infinity and one. Coefficient alpha will be negative whenever there is greater within-subject variability than between-subject variability. A commonly accepted rule of thumb for describing internal consistency is as follows: Very high reliabili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulimia Nervosa
Bulimia nervosa, also known as simply bulimia, is an eating disorder characterized by binge eating followed by purging or fasting, and excessive concern with body shape and weight. The aim of this activity is to expel the body of calories eaten from the binging phase of the process. Binge eating refers to eating a large amount of food in a short amount of time. Purging refers to the attempts to get rid of the food consumed. This may be done by vomiting or taking laxatives. Other efforts to lose weight may include the use of diuretics, stimulants, water fasting, or excessive exercise. Most people with bulimia are at a normal weight. The forcing of vomiting may result in thickened skin on the knuckles, breakdown of the teeth and effects on metabolic rate and caloric intake which cause thyroid dysfunction. Bulimia is frequently associated with other mental disorders such as depression, anxiety, borderline personality disorder, bipolar disorder and problems with drugs or alcohol ...

Diagnostic And Statistical Manual Of Mental Disorders
The ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM; latest edition: DSM-5-TR, published in March 2022) is a publication by the American Psychiatric Association (APA) for the classification of mental disorders using a common language and standard criteria and is the main book for the diagnosis and treatment of mental disorders in the United States and is considered one of the "Bibles" of psychiatry along with the ICD, CCMD and the Psychodynamic Diagnostic Manual. It is usedmainly in the United Statesby researchers, psychiatric drug regulation agencies, health insurance companies, pharmaceutical companies, the legal system, and policymakers. Mental health professionals use the manual to determine and help communicate a patient's diagnosis after an evaluation. Hospitals, clinics, and insurance companies in the United States may require a DSM diagnosis for all patients with mental disorders. Health-care researchers use the DSM to categorize patients for research purp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
