Reliability of the Eating Disorder Examination-Questionnaire in patients with binge eating disorder

This study examined the test-retest reliability of the Eating Disorder Examination-Questionnaire (EDE-Q) in patients with binge eating disorder (BED). Short-term (mean days = 4.8; SD = 3.6) test-retest reliability of the EDE was examined in a sample of 86 patients with BED. Test-retest reliability was excellent for objective bulimic episodes (correlation = .84), but poor to unacceptable for subjective bulimic episodes and objective overeating episodes (correlations = .51 and .39, respectively). Test-retest reliabilities were good for the EDE-Q scales (correlations = .66 to .77), albeit somewhat variable for the individual EDE-Q items (.54 to .78). These findings support the reliability of the EDE-Q for patients with BED. The EDE-Q has utility for assessing the number of binge eating episodes (objective bulimic episodes) and associated features of eating disorders in patients with BED. The results for subjective bulimic episodes are consistent with previous studies in suggesting that these eating behaviors may not be reliable indicators of eating disorders for patients with BED.

A Review of Eating Disorders in Athletes

SUMMARY

The current review aims to evaluate the literature on eating disorders and athletes with the purpose of making recommendations for sport psychologists and other relevant personnel on how to proceed in identifying, managing, and preventing eating disorders in school settings. Whereas the intention of this review is to make recommendations for secondary educational settings, research on other populations such as collegiate and young adult athletes was also reviewed where helpful or where information on adolescent athletes was not available. Recommendations for prevention and intervention include ongoing education of athletes and coaches regarding nutrition, body composition, and performance, using appropriate screening to detect eating disorders, and use of a sport management team to aid in athlete recovery.     

Eating Disorder Recovery

Abstract

Qualitative studies addressing the eating disorder recovery process from the client's point of view are notably absent in the literature. For this case study, we conducted a retrospective examination of the recovery process, as recounted by a 37-year-old female who was diagnosed with anorexia nervosa, binge eating/purging subtype at the age of 30. Two in-person interview sessions provided insight into coping skills, multidisciplinary intervention strategies, and long-term treatment challenges. In sum, the client's perspective can add new information to the understanding of eating disorder recovery from feminist and other theoretical frameworks.     

Health-Related Quality of Life in Women with Eating Disorders: Association with Subjective and Objective Binge Eating

This study examined health-related quality of life (QOL) and its association with different forms of binge eating in 53 women with eating disorders. Participants had enrolled in treatment for anorexia nervosa, bulimia nervosa, binge eating disorder, or other eating disorders not otherwise specified and completed measures of QOL, eating-related psychopathology, and mood disturbance. Eating- and mood-related psychopathology, and to a lesser extent, mental-component QOL scores, were severely impaired in this sample relative to population norms. QOL was significantly and independently predicted by subjective bulimic episodes and compensatory behaviors, including food avoidance, laxative abuse, and self-induced vomiting, accounting for 32% of the variance. Subjective bulimic episodes and food avoidance also independently predicted the physical-component QOL, accounting for 27% of the variance. These findings suggest that subjective bulimic episodes may be independently associated with impairment in QOL and may require specific attention as targets of treatment.     

The Children of Mothers with Eating Disorders

There is good evidence that children of parents with psychological disorders are themselves at increased risk of disturbances in their development. Although there has been considerable research on a variety of disorders such as depression and alcohol, research on the children of parents with eating disorders has been relatively recent. This paper aims to review the evidence and covers a number of areas, including genetic factors, pregnancy, the perinatal and postpartum period, infancy, and the early years of life, focusing on feeding and mealtimes, general parenting functions, and growth. This is followed by a consideration of psychopathology in the children, parental attitudes to children's weight and shape, and adolescence. What is clear is that although there are numerous case reports and case series, the number of systematic controlled studies is relatively small, and almost nothing has been written about the children of fathers with eating disorders. What is evident from the available evidence is that children of mothers with eating disorders are at increased risk of disturbance, but that the risk depends on a variety of factors, and that difficulties in the children are far from invariable. The paper concludes by summarizing five broad categories of putative mechanisms, based on the evidence to date, by which eating disturbance in parents can influence child development.     

错误后减慢理论模型述评

错误后减慢是指错误后正确反应与正确后正确反应相比反应时显著延长的现象.目前研究者已经发现错误后减慢、错误后正确率提高以及错误后干扰效应减少三种错误调控行为,其中错误后减慢是最稳定的错误后行为表现.早期研究主要从冲突监控理论、激活抑制假说、强化学习理论和失匹配理论等角度解释该现象,近年来,研究者又提出了注意朝向理论和评估适应假说.对于该领域未来的研究可以从错误类型、无意识加工、个体差异、新的分析技术的运用方面考虑,以便全面揭示错误后减慢现象的本质.     

Eating patterns and breakfast consumption in obese patients with binge eating disorder

This study examined eating patterns and breakfast consumption, and their relationships to weight and binge eating, in obese individuals with binge eating disorder (BED). One-hundred seventy-three consecutively evaluated men (n=46) and women (n=127) with BED were administered semi-structured interviews and self-report measures to assess the frequency of meals and snacks eaten, as well as binge eating and eating disorder features. Overall, those who consumed more frequent meals, particularly breakfast, and snacks, weighed less. Breakfast, which was eaten on a daily basis by less than half of participants (n=74; 43%), was the least frequently eaten meal of the day. Participants (n=56; 32%) who ate three meals per day weighed significantly less, and had significantly fewer binges, than participants (n=117; 68%) who did not regularly eat three meals per day. Thus, eating more frequently, having breakfast and consuming three meals every day, have potentially important clinical applications for the treatment of BED given that the effectiveness of specific interventions within treatments for BED are unknown, and that weight loss outcome for BED has been poor.     

Eating Disorders Among Urban and Rural African American and European American Women

Abstract

It is alleged that eating disorders are nonexistent in African American women and that eating disorder symptomatology occurs predominantly among White middle class women (Kumanyika, Wilson, & Guilford-Davenport, 1993; Smolak & Striegel-Moore, 2001). This research attempted to identify differences in eating disorder symptomatology in African American and White American women. An eating disorder is a disability because it can damage the person physically, emotionally and socially. It can be undetected for years and society may reinforce the hidden disorder by being complimentary regarding the thin appearance of the person. The Eating Disorder Inventory (EDI) was used to measure psychological traits and symptom clusters associated with the understanding and treatment of eating disorders (Garner, 1990). Measures of self-esteem, depression and coping were also examined. Findings indicated differences between African American and White women on the Ineffectiveness scale of the EDI, differences between the urban/rural women on Ineffectiveness and Perfectionism, and differences in coping strategies and education among this sample group of women. Successful treatment usually involves psychotherapy and/or medication for depression.     

Experiences of Patients in Cognitive Behavioural Group Therapy: A Qualitative Study of Eating Disorders

The aim of this study was to investigate whether there was a difference in skin conductance response between 2 groups of military personnel when exposed to emotionally neutral and charged stimuli. The 2 groups were a combat experience group (n?=?10) with prior experience of emotionally charged war situations and a comparison group (n?=?10) with no such experience. Results showed that the comparison group reacted more strongly to exposure to both charged and neutral pictures than did the combat experience group, regardless of exposure time. The results are discussed in terms of emotional numbing and differences in anxiety state between the 2 groups.     

Slowing Down the Clock: A Review of Experimental Studies Investigating Psychological Time Dilation

A review of 24 experiments investigated the factors that produce a subjective time dilation. The aim of this review was to investigate the magnitude of the obtained time dilation. The mean time duration judgment ratio of subjective time to objective time for the selected studies was 1.31, SD = .24. The analyses revealed that experimental studies investigating subjective time dilation tend to obtain small to moderate time dilation and that several factors can be manipulated in order to make a specific time interval appear longer than it is. Highlighting the factors that lead to a subjective time dilation has both research implications, by pointing to the underlying cognitive mechanisms of time perception, and practical implications, by indicating the factors that can be manipulated in order to control how we perceive time.     

Processing Speed and Neurodevelopment in Adolescent-Onset Psychosis: Cognitive Slowing Predicts Social Function

Onset of psychosis may be associated with abnormal adolescent neurodevelopment. Here we examined the neurocognitive profile of first-episode, adolescent onset psychosis (AOP) as compared to typically developing adolescents, and asked whether neurocognitive performance varied differentially as a function of age in the cases compared with controls. A comprehensive neuropsychological battery was administered to 35 patients experiencing a first-episode of a DSM-IV psychotic disorder and to 31 matched controls. Clinicians also rated subjects’ social and role functioning, both at the time of neuropsychological assessment and 1 year later. Although patients displayed a wide range of impairments relative to controls, their most pronounced deficits included verbal memory, sensorimotor dexterity and cognitive processing speed. Among these, only processing speed showed a significant group-by-age interaction, consistent with an aberrant developmental course among AOP patients. Processing speed also accounted for substantial variance in other areas of deficit, and predicted social functioning 1 year later. AOP patients fail to show normal age-related increases in processing speed, which in turn predicts poorer functional outcomes. This pattern is consistent with the view that adolescent brain developmental processes, such as myelination, may be disrupted in these patients.     

The Spanish language version of the Eating Disorder Examination Questionnaire: comparison with the Spanish language version of the eating disorder examination and test-retest reliability

This study compared the Spanish language questionnaire (S-EDE-Q) and interview (S-EDE) versions of the Eating Disorder Examination and examined the short-term test-retest reliability of the questionnaire version. Seventy-seven monolingual Spanish-speaking Latina women recruited from the community completed the S-EDE-Q and were then administered the S-EDE by fully bilingual doctoral-level research clinicians. The same assessment was repeated after approximately one week (5-14 days). The S-EDE-Q and the S-EDE were significantly correlated on frequencies of binge eating and all four subscales. Mean differences in the frequency of binge eating and the Restraint subscale were not significant, but scores on the Eating Concern, Weight Concern, and Shape Concern subscales differed significantly, with the S-EDE-Q yielding higher scores. Test-retest reliability for the S-EDE-Q was modest for binge eating but was excellent for the subscales (Spearman rho ranged 0.71-0.81), albeit somewhat variable for the individual items. Overall, the acceptable convergence between the S-EDE-Q and the S-EDE for many features of eating disorders and the good short-term test-retest findings provide preliminary support for the use of the S-EDE-Q. These findings, derived using a non-clinical sample of monolingual Spanish-speaking Latina women, require replication and extension. Evaluation with a clinical sample is necessary to further establish the reliability of the S-EDE-Q with an eating disordered group.     

Eating disorder NOS (EDNOS): an example of the troublesome "not otherwise specified" (NOS) category in DSM-IV

The “Not Otherwise Specified” (NOS) category within DSM-IV is designed for disorders of clinical severity that are not specified within broad diagnostic classes. “NOS” diagnoses are intended to be residual categories and they tend to be neglected by researchers. This can be inappropriate. The problems associated with certain NOS diagnoses are well illustrated by “Eating Disorder NOS” (sometimes termed EDNOS), which is the most common category of eating disorder encountered in routine clinical practice yet it has barely been studied. Indeed, there has been no research on its treatment. Interim and longer-term conceptual and practical solutions to the anomalous status of eating disorder NOS are proposed including the creation of a new diagnosis termed “mixed eating disorder”. Several of these solutions are of relevance to NOS categories in general. All the solutions should fulfil criteria for clinical utility.     

Eating disorder pathology among overweight treatment-seeking youth: clinical correlates and cross-sectional risk modeling

Preliminary research suggests that pediatric overweight is associated with increased eating disorder pathology, however, little is known about which overweight youth are most vulnerable to eating disorder pathology. We therefore investigated 122 overweight treatment-seeking youth to describe eating disorder pathology and mental health correlates, and to identify psychopathological constructs that may place overweight youth at increased risk for eating disorder pathology. Youth participated in a comprehensive assessment of eating disorders, mood and anxiety disorders, general psychopathology, and risk variables involving semi-structured clinical interviews and self- and parent-report questionnaires prior to the initiation of weight-loss treatment. Ten youth met criteria for an eating disorder, and over one-third endorsed recent binge eating. Eating disorder pathology was associated with depressive and anxious symptoms (p's<0.001). Structural equation modeling indicated increased negative affect, teasing experience, and thin-ideal internalization, and decreased perfectionism were associated with increased eating disorder pathology. Findings corroborate earlier work indicating that eating disorder pathology is elevated and clinically significant in overweight treatment-seeking youth, bolstering the need for mental health assessment of such individuals. Cross-sectional modeling proposed key variables that relate to eating disorder pathology in overweight treatment-seeking youth, which following prospective replication, may inform the development of effective interventions for overweight and eating disorders.     

Description of an Intensive Dialectical Behavior Therapy Program for Multidiagnostic Clients With Eating Disorders

The authors describe an intensive outpatient dialectical behavior therapy (DBT) program for multidiagnostic clients with eating disorders who had not responded adequately to standard, empirically supported treatments for eating disorders. The program integrates DBT with empirically supported cognitive behavior therapy approaches that are well established for the treatment of eating disorders. Attention is given to inclusion and exclusion criteria, how the program differs from standard treatments for eating disorders, and the application of specific DBT treatment components for multidiagnostic clients with eating disorders.     

时间定价与主观时间流逝速度感对利他行为的影响

采用筛选图片时间任务作为被试利他意愿的指标,考察在两种主观时间流逝速度（时间飞逝和时间缓慢）条件下,被试（时间定价组和非时间定价组）对利他行为的影响。结果发现,非时间定价组在时间飞逝和缓慢条件下利他行为差异不显著,但是时间定价组在时间飞逝条件下比在时间缓慢条件下利他行为时间明显较短。结果表明,时间定价组在时间飞逝条件下充分显现时间的价值,减少利他时间,而在时间缓慢条件下,在可接受的时间成本范围内,被试表现出较为乐于助人,证实了主观时间流逝速度会对个体利他行为产生影响。
