Comparing clinical and research treatments for eating disorders

OBJECTIVE: This study evaluated whether there is a gap between research and practice in the treatment of eating disorders. METHOD: Psychologists in clinical practice (N = 126) were surveyed regarding their treatment of a recent client with an eating disorder and a content analysis of published treatment outcome studies for eating disorders (N = 76) was conducted. RESULTS: The treatment of eating disorders in clinical and research settings was found to differ significantly on several variables, including the types of therapeutic issues addressed and the frequency of comorbidity seen in clients. Logistic regression analyses found that the frequency with which psychologists read journal articles about eating disorders was significantly related to whether their clients received empirically validated treatment. DISCUSSION: Psychologists in clinical practice are not using empirically validated treatments not only because of a lack of training but also because such treatments provide little guidance for dealing with the issues and comorbid problems that their clients with eating disorders often have.     

Objective and subjective binge eating in underweight eating disorders: associated features and treatment outcome

Objective:

To define the utility of the DSM‐IV‐TR definition of binge eating, as it applies to anorexia nervosa (AN) and underweight eating disorder not otherwise specified (ED‐NOS).

Method:

We investigated the psychopathological features associated with bulimic episodes in 105 underweight individuals with eating disorders who reported regular objective bulimic episodes with or without subjective bulimic episodes (OBE group, n = 33), regular subjective bulimic episodes only (SBE group, n = 36) and neither objective nor subjective bulimic episodes (n = 36, no‐RBE group). The Eating Disorder Examination (EDE), anxiety, depression, and personality tests were administered before and upon completion of inpatient cognitive behavior therapy (CBT) treatment 6 months later.

Results:

Compared with the SBE group, OBE subjects had higher body mass index, and more frequent self‐induced vomiting, while both OBE and SBE groups had more severe eating disorder psychopathology and lower self‐directness than the no‐RBE group. Dropout rates and outcomes in response to inpatient CBT were similar in the three groups.

Discussion:

Despite a few significant differences at baseline, the similar outcome in response to CBT indicates that categorizing patients with underweight eating disorder on the basis of the type or frequency of bulimic episodes is of limited clinical utility. © 2011 by Wiley Periodicals, Inc.

The interaction of personality disorders and eating disorders: a two-year prospective study of patients with longstanding eating disorders

OBJECTIVE: The current study aimed to investigate the relation between personality disorders and symptoms of both eating disorders and general psychopathology over time. METHOD: Seventy-four patients, with a mean age of 30 years and admitted to a hospital for treatment of a chronic eating disorder, were assessed using the Eating Disorder Inventory (EDI), the Eating Disorder Examination (EDE), the Symptom Check List-90-Revised (SCL-90-R), and the Structured Clinical Interview for DSM-IV Axis II disorders (SCID-II) at admission, and after 1 and 2 years. RESULTS: At the 2-year follow-up, there was considerable reduction in both personality and symptoms (effect size = 0.83-0.94). Panel modeling using structural equation modeling techniques indicated that symptomatic changes generally preceded changes in the personality disorder. DISCUSSION: Eating disorder symptoms and general symptomatology had direct effects on a dimensional personality disorder index. Thus, personality disorders may be at least partially a consequence of general symptomatology in chronic eating disorders. Symptom improvement appears to precede changes in personality in this sample of patients with chronic eating disorders.     

Nutrition education in the treatment of eating disorders: a suggested 10 session course

Research has shown that many patients with eating disorders have poor nutritional knowledge. A dietitian can provide nutritional information and guidance to enable the patient to make food choices based on fact, not fear. The 10 session schedule presented here is designed to present factual information, then the opportunity for the individual to apply this to themselves. The format makes particular reference to the low body weight patient. The course can be used either in individual or group sessions.     

Barriers to treatment for eating disorders among ethnically diverse women.

OBJECTIVE: This study examined barriers to treatment in an ethnically diverse community sample of women with eating disorders. METHOD: Participants were 61 women (22 Hispanics, 8 Asians, 12 Blacks, 19 Whites) with eating disorders. Diagnosis was determined using the Eating Disorder Examination. Treatment-seeking history, barriers to treatment seeking, ethnic identity, and acculturation were assessed. RESULTS: Although 85% of the sample reported wanting help for an eating problem, only 57% had ever sought treatment for an eating or weight problem. Individuals who had sought treatment reported being significantly more distressed about their binge eating than those who had not sought treatment and having begun overeating at a younger age. Of those who had sought help, 86% had not received any treatment for their eating problems. The main barriers to treatment seeking were financial reasons. CONCLUSION: Women from minority groups who have eating disorders are underdiagnosed and typically not treated.     

Screening for eating disorders and high-risk behavior: caution

OBJECTIVE: The current study reviews the state of eating disorder screens. METHODS: Screens were classified by their purported screening function: identification of cases with (a) anorexia nervosa only; (b) bulimia nervosa only; (c) eating disorders in general; (d) partial syndrome, eating disorder not otherwise specified (EDNOS), or subclinical; (e) not a-d but at high risk. Information is presented on development, psychometric properties, and external validation (e.g., sensitivity, specificity, positive predictive values, and negative predictive values). RESULTS: Screens differ widely with regard to objective, psychometric properties and the validation methodology used. Most screens that identify cases are not appropriate for the identification of at-risk behaviors. Little data on the external validity of screens are available. DISCUSSION: Screens should be used with caution. A sequential procedure, in which subjects identified as being at risk during the first stage is followed by more specific diagnostic tests during the second stage, might overcome some of the limitations of the one-stage screening approach.     

Season of birth and eating disorders: patterns across diagnoses in a specialized eating disorders service

OBJECTIVE: In view of inconsistent findings from previous studies, the aim was to investigate possible seasonal variation in month of birth in patients with anorexia nervosa, bulimia nervosa, and eating disorder not otherwise specified. METHOD: We examined the month of birth in a cohort of 1,305 adult patients with a DSM-IV eating disorder diagnosis at first presentation to a specialized eating disorders service. RESULTS: When compared to general population data, we found no evidence of significant variation in month or season of birth in anorexia nervosa, bulimia nervosa, or eating disorder not otherwise specified. CONCLUSION: The authors question whether people who develop eating disorders differ from the general population in their season of birth. Caution is expressed about further speculation regarding the etiological significance of season of birth in eating disorders.     

Sensor technology implementation for research,treatment, and assessment of eating disorders

Sensor technology has made huge technological advances in the past decade. Many sensor technologies (e.g., wearable wristbands) have been integrated into health research with the ability to substantially improve health outcomes and reduce health care costs. Despite the rapid technological developments in sensor technology, little research has examined sensor technology in eating disorders (EDs). The overarching aim of the current article is to briefly review the literature on sensor technology and health outcomes, including EDs, and discuss several potential ideas for the application of sensor technology in the treatment, assessment, and diagnosis of EDs. We will also present data from a feasibility case study with an ED participant and healthy control providing a brief example of how wearable sensor technology might be implemented in ED research. Overall, we will discuss how sensor technology could be used to improve treatment and assessment of EDs and represents an idea in need of more research in the ED field.     

Using imagery in cognitive-behavioral treatment for eating disorders: tackling the restrictive mode

A restrictive thinking style in the eating disorders, often referred to as "anorexic thinking," is often resistant to cognitive-behavioral interventions, even when apparent motivation is relatively high. It is argued that this difficulty is due in part to the ingrained nature of such thinking patterns, regardless of diagnosis. Those patterns reflect the ego-syntonic element of the eating disorders, and manifest as difficulty for the patient in identifying and challenging negative automatic thoughts and maladaptive core beliefs. There is a need to develop cognitive techniques that allow the individual to identify maladaptive cognitions as reflecting their restrictive schema mode, rather than being the only way of thinking and seeing the world. This study describes the use of imagery to enable patients to distinguish the restrictive thoughts from other cognitive perspectives. The restrictive "mode" is presented as part of the individual's personality structure (drawing on cognitive-behavioral models of personality), rather than being an external entity. This technique is designed to facilitate conventional cognitive-behavioral therapy, freeing the patient to challenge her cognitions and to engage in behavioral experiments. We present case material to illustrate this technique and its use in conjunction with other cognitive-behavioral techniques. Future directions and potential limitations are also discussed.     

The introduction of treatment and the cultural adaptability of western psychotherapies for eating disorders in China

In the past 40 years, the prevalence of eating disorders (ED) in China has shown an increasing trend, leading to an urgent need to develop efficient treatment modes and methods. Since the beginning of the new century, the diagnosis, treatment, and research of ED in China have been under development. This article gives an introduction and commentary on the treatment modes, treatment methods and their applications in ED in China. There are two main treatment forms for ED until now, that is, inpatient treatment and outpatient treatment. Inpatient treatment is recommended as the first choice. Since 2008, clinical psychotherapies such as cognitive behavioral therapy (CBT), dialectical behavioral therapy (DBT), and family-based treatment (FBT), which are effective for pathological symptoms of ED, have been introduced into China and developed clinically. Group CBT and group DBT for patients with ED and group FBT for caregivers might be the most efficient psychotherapy in China nowadays. A multi-family FBT support group could be developed as the basic treatment of ED patients. Although these new types of psychotherapy have observed effectiveness in clinical application, the Randomized Controlled Trials (RCT) are rare and need to be developed.
