Eating Disorders: Steps Towards an Increased Understanding
Uppsala University, Disciplinary Domain of Humanities and Social Sciences, Faculty of Social Sciences, Department of Psychology.
2014 (English)Doctoral thesis, comprehensive summary (Other academic)
Abstract [en]

Eating disorders and disordered eating attitudes and behaviors are characterized by an over-evaluation of weight and shape, under or over-controlled eating, as well as engagement in compensatory behaviors. The disorders are associated with psychological suffering, acute and long-term health impairments, a high rate of suicide attempts as well as an increased risk of mortality. Knowledge regarding the etiology of eating disorders is limited and based on current models it is not possible to adequately predict either who will get an eating disorder or who will recover. This lack of understanding has hindered the development of effective prevention and treatment interventions.

The aim of the present thesis was to contribute towards an increased understanding of eating disorders and disordered eating attitudes and behavior through the collection of norms and psychometric data, investigation of risk factors and their roles, and focusing on the understudied group of males with eating disorders. Five studies were included. Specifically, Study I focused on collecting general population and clinical norms on the well-established Eating Disorder Examination Questionnaire (EDE-Q) and the Clinical Impairment Assessment Questionnaire (CIA). Study II both collected general population norms on, and investigated psychometric properties of, the Body Shape Questionnaire (BSQ-8C), an instrument intended to assess body dissatisfaction. Study III focused on the role of perfectionism (an established risk factor for eating disorders) as a possible mediator or moderator between body dissatisfaction and disordered eating behavior and attitudes. Finally, in Study IV and V attention was placed on males. In Study IV the specific aim was to compare the clinical characteristics between young males and females with eating disorders while in study V the specific aim was to explore variables associated with disordered eating among young males based on a compilation of factors known to play a role among females as well as factors thought to be uniquely associated with males, such as sexual orientation and drive for muscularity. A greater understanding of eating disorders will help reduce the stigma that is associated with eating disorders, easing the way for affected individuals to seek help and ultimately improve the development of effective prevention and intervention.

Abstract [en]

Optimal use of assessment instruments for the detection and diagnosis of eating disorders (ED) depends on the availability of normative data. The aim of this work was to, for the first time, collect norms for both the Eating Disorder Examination Questionnaire (EDE-Q) and the newly developed Clinical Impairment Assessment (CIA) Scale from a general population of young women in Sweden, as well as from a clinical population of ED patients in Sweden. Participants were composed of both a randomized sample from the general population of women aged 18-30 years (N = 760) as well as from a clinical population aged 18-66 years (N = 2383). Data for the clinical population was extracted from the Stepwise database. Mean scores, standard deviations and percentile ranks for the global for the EDE-Q (as well as its subscales) and the CIA are presented. Prevalence figures of key eating disorder behaviors are also reported. Comparisons are made between the results in the present study with other existing normative studies on the EDE-Q and the CIA. The present study contributes to improving the accuracy of the interpretation of scores of the widely used self-report measure of ED, the EDE-Q, and the CIA, both of which play important roles in for diagnosis, prevention and intervention of ED.

Abstract [en]

There is a need for brief, sensitive, and reliable instruments for contextual assessment of body dissatisfaction. Suitable selection and optimal use of psychological assessment instruments requires appropriate psychometric as well as normative data. Two studies were conducted to investigate the psychometric properties and collect general population norms for a short, eight item version of the Body Shape Questionnaire (BSQ-8C). In the first study, a sample of undergraduate students (N=182) was recruited to investigate the psychometric properties of the BSQ-8C, while in the second study a sample from the general population of Swedish women aged 18-30 years (N=747) was used to collect norms. The test-retest reliability, internal consistency, and convergent validity for BSQ-8C were high. Given the questionnaire's briefness and good psychometric properties, particularly when used in conjunction with norms, the BSQ-8C is considered a valuable instrument for measuring body shape dissatisfaction among young adult women.

Abstract [en]

A link between perfectionism and disordered eating has been documented in previous studies. The purpose of the current study was to expand our knowledge of the specific role of perfectionism in disordered eating by examining perfectionism as a mediator or a moderator in the relation between body dissatisfaction and disordered eating (assessed using the EAT-26 and its subscales. and the Binge Scale) We sampled a large ethnically diverse sample of university women (N = 520) using two measures of perfectionism the Eating Disorder Inventory Perfectionism subscale (EDI-P) and the Multidimensional Perfectionism Scale (H-MPS) In general, socially prescribed and self-oriented perfectionism, but not other-oriented perfectionism, were correlated with disordered eating attitudes and behaviors, except binge eating. Furthermore, perfectionism was found to partially mediate and moderate the relation between body dissatisfaction and disordered eating, however the strength of these associations differed depending on both the particular measure of perfectionism (EDI-P versus H-MPS) and the specific dimension of perfectionism (self-oriented, socially prescribed, other-oriented) used in the analyses. The findings are discussed in relation to the need for more informed and theoretically sound models of the development and maintenance of disordered eating.

Abstract [en]

Background: Eating disorders (ED) are serious disorders that have a negative impact on both the psychological and the physiological well-being of the afflicted. Despite the fact that ED affect both genders, males are often underrepresented in research and when included the sample sizes are often too small for separate analyses. Consequently we have an unclear and sometimes contradictory picture of the clinical characteristics of males with ED. The aim of the present study was to improve our understanding of the clinical features of adolescent males with eating disorders. Methods: We compared age at presentation, weight at presentation, history of significantly different premorbid weight and psychiatric (Attention Deficit Hyperactivity Disorder (ADHD)) and somatic comorbidity (celiac disease and diabetes) of 58 males to 606 females seeking medical care for eating disorders at the Children's Hospital in Uppsala, Sweden during the years 1999-2012. As all boys were diagnosed with either AN or Other Specified Feeding or Eating Disorder (OSFED) atypical AN, the age and weight comparisons were limited to those girls fulfilling the diagnostic criteria for AN or OSFED atypical AN. Results: There was no significant difference in age at presentation. Differences in weight at presentation and premorbid weight history were mixed. A significantly higher percentage of males had a history of a BMI greater than two standard deviations above the mean for their corresponding age group. As well, there was a higher prevalence of ADHD among the males whereas celiac disease and diabetes only was found among the females. Conclusions: A better understanding of the clinical characteristics of males with ED at presentation should improve our ability to identify males with ED and thereby aid in tailoring the best treatment alternatives.
