Lewandowska K, Klinkosz W, Styk W, Kowalczyk M. Diversity of Binge-Eating Disorder Symptoms Is Associated with Anxiety about Getting Fat Rather Than Body Image: A Clinical Study of Women in Poland. Nutrients 2023; 15:4572. [PMID: 37960225 PMCID: PMC10647494 DOI: 10.3390/nu15214572] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2023] [Revised: 10/21/2023] [Accepted: 10/26/2023] [Indexed: 11/15/2023] Open
Abstract
BACKGROUND Anxiety about gaining weight is strongly related to body image. Evidence indicates that body dissatisfaction is a strong predictor of eating disorder development. Although not included in DSM-V diagnostic criteria, body image dissatisfaction, and concern are clearly relevant also for individuals with binge-eating disorder (BED). Weight gain anxiety is associated with psychopathological behaviors, but existing research in this area is primarily focused on bulimia nervosa and anorexia nervosa. The goal of this present study was to investigate body image and body mass anxiety in people with BED. METHODS Women diagnosed with BED (n = 105) aged 18 to 66 were surveyed using the questionnaire developed by the authors evaluating the presence of BED symptoms based on DSM-V criteria, and two other instruments: the Body Esteem Scale (BES), and the Body Mass Anxiety Scale (BMAS-20). Statistical analyses were conducted to examine the correlations of BED with body image and body mass anxiety (Pearson's r), to test differences between groups with greater and lesser BED symptom diversity (Student's t-test or the Mann-Whitney U test), and to assess differences among mild-, moderate- and severe-BED groups (ANOVA with a post-hoc test). RESULTS A medium positive relationship was found between anxiety about getting fat (AGF) and the diversity of BED, measured as the number of BED symptoms. A larger number of BED symptoms was shown to be associated with a higher level of AGF. However, no significant differences in AGF levels were observed among BED-severity groups, specified with the frequency of binge eating episodes. No correlations were found between BED and body image. There were also no significant differences in body image between groups with a larger and a smaller number of BED symptoms. The only significant difference in body image observed among BED-severity groups was the level of weight concern. People with mild BED displayed a higher level of weight concern than those with severe BED. CONCLUSIONS Women who binge eat experience high levels of AGF. In the present study, AGF was primarily associated with the number of BED symptoms and not the rate of recurrence of binge-eating episodes. The frequency of BED episodes, however, was linked with weight concern. On the other hand, the hypothesized relationship between disturbed body image and BED was not confirmed. The findings indicate that anxiety about getting fat should be viewed as one of the psychological costs incurred by women experiencing BED symptoms, and it should be mentioned in the next DSM version.

One body, two faces: How double standards influence body evaluation in women with binge-eating disorder compared to mentally healthy women with higher weight and average weight.

Abstract
OBJECTIVE Research has found evidence that women with anorexia nervosa (AN) and bulimia nervosa (BN) apply different standards for themselves than for others when evaluating bodies, an aspect of a disturbed body image. This study investigates whether women with binge-eating disorder (BED) likewise show self-deprecating double standards (DS). METHODS Women with BED (n = 40), women with higher weight (n = 40) and women with average weight (n = 40) viewed a presentation of different builds, including their individual ideal body, which were presented once with participants' own and once with an unknown woman's face. After each presentation, participants rated their emotional response regarding arousal and valence, and evaluated the body's attractiveness, body fat and muscle mass. DS were defined as the difference in ratings of the same body with one's own and the unknown face. RESULTS Women with BED showed a higher degree of negative emotions in response to a thin and a high-weight build, rated lower levels of body attractiveness for an athletic build, and displayed more arousal for almost all builds presented with their own compared to with another face. While women with BED showed a higher burden on measures of eating pathology and body image than the other groups, DS were not more pronounced in women with BED. DISCUSSION The findings contradict DS as a characteristic feature of BED, but underline "normative" DS for higher-weight/high-weight builds, reflecting weight stigmatization. Psychoeducation on these DS might complement cognitive-behavioral therapy in BED in order to reduce negative emotions. PUBLIC SIGNIFICANCE A bias in body evaluation has been proven in women with anorexia and BN, but no research has examined this in women with BED. This study provides evidence of DS in body evaluation in women with BED, compares the extent of DS between women with BED, higher weight, and average weight, and investigates individual body ideals in women with BED and higher weight.

Body weight distortions in an auditory-driven body illusion in subclinical and clinical eating disorders. Sci Rep 2022; 12:20031.

Abstract
Previous studies suggest a stronger influence of visual signals on body image in individuals with eating disorders (EDs) than healthy controls; however, the influence of other exteroceptive sensory signals remains unclear. Here we used an illusion relying on auditory (exteroceptive) signals to manipulate body size/weight perceptions and investigated whether the mechanisms integrating sensory signals into body image are altered in subclinical and clinical EDs. Participants' footstep sounds were altered to seem produced by lighter or heavier bodies. Across two experiments, we tested healthy women assigned to three groups based on self-reported Symptomatology of EDs (SED), and women with Anorexia Nervosa (AN), and used self-report, body-visualization, and behavioural (gait) measures. As with visual bodily illusions, we predicted stronger influence of auditory signals, leading to an enhanced body-weight illusion, in people with High-SED and AN. Unexpectedly, High-SED and AN participants displayed a gait typical of heavier bodies and a widest/heaviest visualized body in the 'light' footsteps condition. In contrast, Low-SED participants showed these patterns in the 'heavy' footsteps condition. Self-reports did not show group differences. The results of this pilot study suggest disturbances in the sensory integration mechanisms, rather than purely visually-driven body distortions, in subclinical/clinical EDs, opening opportunities for the development of novel diagnostic/therapeutic tools.

Abstract
PURPOSE Despite the claim to integrate body image interventions in obesity treatment, little is known about the mechanisms involved in maintaining body dissatisfaction in persons with overweight and obesity. Therefore, the present study sought to investigate attentional processing of body stimuli in women with overweight and obesity (OW). METHODS Women with OW (n = 82) and normal weight controls (NW; n = 44) conducted two eye-tracking paradigms. In the first paradigm, fixation duration on the subjectively most beautiful and ugliest body part of one's own and a weight-matched control body were analyzed. In the second paradigm, picture pairs including the own and a control body or object were presented and initial fixation orientation was measured. Automatic and intentional processing of the body pictures was manipulated by either indicating on which side which stimuli would appear or not. RESULTS Women with OW displayed a bias towards the ugliest as opposed to the most beautiful body part, whereas women with NW showed a balanced viewing pattern. Furthermore, both groups showed a preference for bodies relative to the object. However, only women with OW preferred their own relative to the control body during intentional processing. CONCLUSION Taken together, results point towards a self-focused and deficit-oriented gaze pattern in women with overweight and obesity. Targeting these processes might help to improve obesity treatment outcomes. LEVEL OF EVIDENCE Level I, experimental study.

Abstract
Body image disturbance is core to the psychopathology of eating disorders (EDs), and related disorders such as muscle dysmorphia (MD). Global measures of body image fail to quantify specific aspects of body image disturbance that characterizes EDs, and may be differentially associated to outcomes. The aim of this systematic review was to provide an overview of specific body image facets and synthesize findings from controlled studies that compared clinical ED/MD and control-comparison groups in body image disturbance. One-hundred sixty-seven studies met inclusion criteria, and reported on comparisons among 30,584 individuals in 28 body image facets, which were more broadly grouped into evaluative, perceptual, cognitive-affective and motivational categories for the purpose of the present review. Effect sizes were calculated as Cohen's d for every comparison between ED and control groups. Body dissatisfaction (evaluative category) was the most prevalent facet assessed across studies (62 %), and differences between clinical and control groups were the largest in this category, especially for bulimia nervosa (d = 1.37). Scarcity of studies with male and MD clinical samples, and use of single-item and non-validated measures, should encourage development of instruments for body image facets pertinent to EDs and MD that can be validly applied across gender.

Abstract
INTRODUCTION: The literature remains scarce on the late effects of bariatric surgery on the general health of patients who underwent such procedures at an older age. The present study aimed to evaluate depression and anxiety symptoms, risky alcohol consumption, and binge eating in older adults undergoing bariatric surgery. METHODS: This study used current data (from medical records and tests) to conduct a cross-sectional study. A total of 74 individuals aged 60 years and older who underwent bariatric surgery after 55 years of age at a specialist center for obesity management located in Brazil were included and evaluated by the Beck Depression Inventory, Beck Anxiety Inventory, Alcohol Use Disorders Identification Test, and Binge Eating Scale. Demographic and clinical data related to the surgical procedure (weight loss) were also collected. The Cochran-Armitage trend test, Pearson’s χ2 test, and a multiple linear regression model were used as needed. A p < 0.05 was considered significant. RESULTS: The individuals were white (65.70%) and women (78.30%), with a mean age of 65.8 (SD 3.90) years. The mean time elapsed from surgery to evaluation was 75.70 (SD 43.70) months; 10.80% of the participants had moderate to severe depression, 8.10% moderate to severe anxiety, and 5.40% risky or high-risk alcohol consumption. None of the participants had binge eating problems. Weight regain was not associated with depressive symptom severity or risky alcohol consumption, but it was significantly associated (p = 0.034) with few or neither anxiety symptoms. Excess weight loss was not associated with any study variable. CONCLUSION: The results show a low prevalence of mental symptoms in older adults undergoing bariatric surgery compared to data from the literature on younger adults undergoing the same procedure.

Abstract
PURPOSE A common challenge among a subgroup of individuals with obesity is binge eating, that exists on a continuum from mild binge eating episodes to severe binge eating disorder (BED). BED is common among bariatric patients and the prevalence of disordered eating and ED in bariatric surgery populations is well known. Conventional treatments and assessment of obesity seldom address the underlying psychological mechanisms of binge eating and subsequent obesity. This study, titled PnP (People need People) is a psychoeducational group pilot intervention for individuals with BED and obesity including patients with previous bariatric surgery. Design, feasibility, and a broad description of the study population is reported. MATERIAL AND METHODS A total of 42 patients were from an obesity clinic referred to assessment and treatment with PnP in a psychoeducational group setting (3-hour weekly meetings for 10 weeks). Of these, 6 (14.3%) patients had a previous history of bariatric surgery. Feasibility was assessed by tracking attendance, potentially adverse effects and outcome measures including body mass index (BMI), eating disorder pathology, overvaluation of shape and weight, impairment, self-reported childhood difficulties, alexithymia, internalized shame as well as health related quality of life (HRQoL). RESULTS All 42 patients completed the intervention, with no adverse effects and a high attendance rate with a median attendance of 10 sessions, 95% CI (8.9,9.6) and 0% attrition. Extent of psychosocial impairment due to eating disorder pathology, body dissatisfaction and severity of ED symptoms were high among the patients at baseline. Additionally, self-reported childhood difficulties, alexithymia, and internalized shame were high among the patients and indicate a need to address underlying psychological mechanisms in individuals with BED and comorbid obesity. Improvement of HRQoL and reduction of binge eating between baseline and the end of the intervention was observed with a medium effect. CONCLUSION This feasibility study supports PnP as a potential group psychoeducational intervention for patients living with BED and comorbid obesity. Assessments of BED and delivery of this intervention may optimize selection of candidates and bariatric outcomes. These preliminary results warrant further investigation via a randomized control trial (RCT) to examine the efficacy and effectiveness of PnP.

Abstract
Bulimic behavior and the associated experience of one's own body are of great importance in the course of surgical treatment for obesity. This study determined the predictive role of multidimensional body image on bulimic-type eating behaviors among individuals scheduled for the surgical treatment of obesity. This study was conducted in a clinical setting on a group of 100 obese patients who were treated at the Centre for the Surgical Treatment of Obesity at the University Hospital in Krakow (Poland) and were qualified for bariatric surgery. Body image was examined with Cash's Multidimensional Body-Self Relations Questionnaire (MBSRQ) and bulimic behavior with David M. Garner's Eating Attitudes Test (EAT-26). Part A of the EAT-26 focused only on the bulimia and food preoccupation scale. Part B included sex, age, and body mass index (BMI) in the predictive model. A stepwise multiple regression analysis was conducted to assess psychological predictors of eating behavior. For binary variables, a logistic regression analysis was conducted for the whole group and for the women's group alone. Owing to the small sample size of men, regression analyses were not conducted. Higher values were observed in the Appearance Orientation dimension among women when compared to men. Appearance evaluation and age were found to be significant predictors for bulimic behaviors in the whole group. In regression models for behavior in the last 6 months, the predictors were found to be Health Evaluation and Appearance Orientation for laxative use, and Overweight Preoccupation for vomiting for weight control. Health-promoting behaviors in obesity treatment were conditioned as follows: for exercise, the predictors were sex and Fitness Orientation and for weight loss, they were Overweight Preoccupation and Body Areas Satisfaction. Our study shows that different bulimic behaviors are variously conditioned by body image dimensions, some of which are predictors of behaviors that are risk factors for obesity and poor outcomes of bariatric treatment, whereas others increase the chance of pro-health behaviors among obese individuals.

Abstract
Eating disorder tendencies are psychological characteristics that are prevalent in healthy young females and are known to be among the risk factors for eating disorders such as anorexia and bulimia nervosa. People with greater eating disorder tendencies strongly associate sweet and fatty foods with weight gain and strictly avoid consuming such foods. However, little is known about how eating disorder tendencies influence the association between taste and body shape impression. Research on crossmodal correspondences suggests that people preferentially associate sweet tastes with round shapes, and individual differences affect the degree of such associations. This study investigates how the degree of taste-shape matching is related to eating disorder tendencies with a preliminary investigation of what mediates this relationship. Two experiments were conducted: in Experiment 1, healthy participants rated the degree of association between basic taste words (sweet/sour/salty/bitter) and roundness of shape and subsequently completed questionnaires addressing eating disorder tendencies. In Experiment 2, participants answered additional questionnaires addressing obsessiveness, dichotomous thinking, and self-esteem. The results of Experiment 1 indicated a positive correlation between drive for thinness, which is one indicator of an eating disorder tendency, and the degree of matching sweetness to round shape. Experiment 2 replicated the results of Experiment 1 and revealed the mediating effect of obsessiveness. These findings suggest a relationship between individual differences in taste-shape matching and eating disorder tendency and the preliminary mediating role of obsessiveness. The present study provides new insight into the role of sweet-round matching in eating disorder tendencies and the associated psychological mechanisms.

Abstract
Recently, there has been an increasing focus on body image dissatisfaction (BID), both as a motivational factor for seeking bariatric surgery and as a factor influencing weight loss outcome after surgery. Although associations have been reported between BID, emotional distress and successful weight loss, conclusions are limited due to methodological issues such as non-weight-specific assessment tools for body image and neglect of behavioral components (e.g. body avoidance, BA). The present study seeks to report on BID and BA 9 years after bariatric surgery using a cross-sectional data set from the 9-year follow-up assessment of the Essen-Bochum Obesity Treatment Study (EBOTS). In total, N = 291 participants of the original EBOTS sample were included in the present analyses (N = 78 bariatric surgery patients, SURG; N = 124 patients of a conventional treatment program, CONV; and N = 83 individuals with obesity not seeking treatment, OC). Current body image facets (BID and BA) were captured at the 9-year follow-up assessment via silhouette scales adapted for use in samples with obesity. Moreover, BID was assessed retrospectively to obtain baseline attitudes. Possible influences of eating disorder symptoms and depression/anxiety were controlled for and assessed via standardized self-report measures. The results imply an improvement in BID in the SURG group, but not in the CONV and OC groups. The level of BA in relation to clothing was significantly higher in the CONV group compared to both the SURG and OC group. Current BID as well as BA were positively associated with current body weight as well as depression, anxiety, and levels of disinhibited eating. A positive change from baseline to current levels of BID was associated with successful weight loss, independently of treatment. The findings emphasize the role of the different components of body image after surgery for mental health features, and suggest a robust relationship between BID and weight loss (success). Thus, it might be helpful to address BID in treatment. However, further research, particularly in the form of prospective studies, is necessary to determine the direction of influence.

[PMID: 31696674 PMCID: PMC6908865 DOI: 10.1002/brb3.1458] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/28/2019] [Accepted: 10/05/2019] [Indexed: 02/06/2023] Open
Abstract
OBJECTIVE The current systematic and methodological review aimed to critically review existing literature utilizing implicit processing, or automatic approach- and/or avoidance-related attentional biases between eating disorder (ED) and nonclinical samples, which (a) highlights how psychophysiological methods advance knowledge of ED implicit bias; (b) explains how findings fit into transdiagnostic versus disorder-specific ED frameworks; and (c) suggests how research can address perfectionism-related ED biases. METHOD Three databases were systematically searched to identify studies: PubMed, Scopus, and PsychInfo electronic databases. Peer-reviewed studies of 18- to 39-year-olds with both clinical ED and healthy samples assessing visual attentional biases using pictorial and/or linguistic stimuli related to food, body, and/or perfectionism were included. RESULTS Forty-six studies were included. While behavioral results were often similar across ED diagnoses, studies incorporating psychophysiological measures often revealed disease-specific attentional biases. Specifically, women with bulimia nervosa (BN) tend to approach food and other body types, whereas women with anorexia nervosa (AN) tend to avoid food as well as overweight bodies. CONCLUSIONS Further integration of psychophysiological and behavioral methods may identify subtle processing variations in ED, which may guide prevention strategies and interventions, and provide important clinical implications. Few implicit bias studies include male participants, investigate binge-eating disorder, or evaluate perfectionism-relevant stimuli, despite the fact that perfectionism is implicated in models of ED.

Abstract
Body image interventions have been shown to reduce self-reported cognitive-emotional facets of body image disturbance in binge eating disorder (BED). However, more objective assessment methods are required to evaluate the effects of these interventions. Therefore, the present study aimed at investigating the usefulness of vocally encoded emotional arousal as physiological correlate of body dissatisfaction during mirror exposure in women with BED. Women with BED (n = 60) and weight-matched controls (CG; n = 60) participated in an experimental thought-sampling procedure including a mirror exposure and a control condition in a repeated-measures design. Fundamental frequency as a vocal correlate of emotional arousal as well as negative, neutral, and positive body-related cognitions during both conditions were analyzed. In line with our hypotheses, the BED group verbalized more negative, and less positive and neutral body-related cognitions during the mirror exposure condition compared to the CG. Contrary to our hypotheses, though, there was a stronger increase in physiological arousal between the control and the mirror exposure condition in the CG relative to the BED group. Furthermore, a significant negative correlation between fundamental frequency and the severity of cognitive-emotional body image disturbances emerged. The findings indicate a cognitive-emotional over-involvement with physical appearance during mirror exposure in women with BED compared to weight-matched controls in the absence of a corresponding physiological pattern. Results are discussed in terms of an impaired ability of women with BED to show adequate physiological responses to body-related stress. In addition, methodological recommendations for future research are presented.

Abstract
Body dissatisfaction, the negative subjective evaluation of one's body, is associated with many negative psychological and physical health consequences. One conceptualization of body dissatisfaction includes an experience of discrepancy between perceived actual and ideal body shapes. This paper reviews the literature on three facets of body dissatisfaction from the framework of self-discrepancy theory: perceptions of current weight, ideal body weight, and the relative importance of conforming to ideals. We review components of body dissatisfaction among healthy individuals and eating-disordered individuals. We also address the conceptualization's relationship among body dissatisfaction, weight history, and dieting to expand the impact of body dissatisfaction research and to provide more information on the nature and treatment of eating disorders.

Abstract
The goal of the present review is to give an overview of the current findings on various facets of body image disturbance in Binge Eating Disorder such as body dissatisfaction, overconcern with weight and shape, body-related checking and avoidance behavior, misperception of body size, and body-related cognitive bias. In addition, treatments for a disturbed body image in BED and evidence of body image disturbance in youth with binge eating are reviewed. The results show that a disturbed body image in BED is present in the form of overconcern with weight and shape. Furthermore, there are hints that body dissatisfaction, as well as body-related checking and avoidance behavior, are also impaired. Research concerning misperception of body size in BED has been neglected so far, but first findings show that individuals with BED rate their own body shape rather accurately. Furthermore, there are first hints that body-related cognitive biases are present in individuals with BED. Moreover, in children and adolescents, there are first hints that body dissatisfaction, as well as shape and weight concerns, seem to be associated with loss of control and binge eating. Treatments aimed directly at the convertibility of a disturbed body image in BED have revealed encouraging outcomes. In conclusion, body image disturbance seems to occur in BED, and first studies show that it can be treated effectively.

Abstract
Body checking (BC) and avoidance behaviors (BA) are the dominant behavioral features of body image disturbances (BID) that characterize most individuals with eating disorders (EDs). Whereas BC can be reliably assessed, a valid assessment tool for BA is lacking, preventing an adequate assessment of BID differences across different EDs (anorexia nervosa, AN; bulimia nervosa, BN; binge eating disorder, BED). A total of 310 women with EDs and 112 nonclinical controls completed measures of BC-, BA- and ED-related symptoms. BA did not differentiate between EDs, whereas BC did: it was highest in AN and BN, and lowest in BED. Multivariate analyses also discriminated AN from BN based on BC. Given that results are of preliminary nature, evidence is promising that EDs can be discriminated from healthy controls and that differential BID profiles for the behavioral component among ED subgroups exist. However, replication of the factor structure remains open within ED subsamples.

Effects of a cognitive-behavioral exposure-based body image therapy for overweight females with binge eating disorder: a pilot study. J Eat Disord 2017; 5:43.

Abstract
BACKGROUND Although not part of the diagnostic criteria of the DSM-5, body image disturbance seems to be a relevant feature of Binge Eating Disorder (BED) as well as of other eating disorders such as Anorexia Nervosa (AN) or Bulimia Nervosa (BN). Hence, the aim of the present pilot study was to assess the changeability of body image disturbance in a sample of overweight females with BED by a cognitive-behavioral treatment, directly addressing body image disturbance. METHOD Overweight females (N = 34) with BED were randomized to a manualized body image therapy or a waiting-list control group. The final sample consisted of n = 15 participants in the intervention group and n = 19 in the control group due to two drop-outs in the control condition. Before and after the intervention or the waiting period, respectively, participants filled out a questionnaire battery assessing several body image and eating disorder related features. To quantify the perceptual component of body image disturbance, a digital photo distortion technique based on a picture of each participant taken in a standardized suit was applied. RESULTS In a two-way ANOVA, significant Time × Group interactions were found for eating and shape concerns, drive for thinness, body dissatisfaction, depressiveness and low self-esteem. Follow-up t-tests indicated a significant symptom reduction of a generally high magnitude in the intervention group. No significant changes concerning body checking and the estimations of one's own "real", "felt" and "ideal" body dimensions were found. CONCLUSION The strong symptom reduction in the cognitive-affective component of body image disturbance indicates that an exposure-based cognitive-behavioral body image intervention is a promising treatment module for overweight females with BED, but future research with a larger sample size is needed to quantify possible changes in all components of body image.

Abstract
In terms of the transdiagnostic model of eating disorders, Anorexia Nervosa (AN), Bulimia Nervosa (BN), and Binge Eating Disorder (BED) share the same distinctive psychopathology. However, empirical evidence showing similarities between these eating disorder diagnoses for core symptoms is scarce, and the role of weight status is unclear. Data from a total of 168 female participants were collected between April 2004 and April 2008, at an outpatient unit specialized in eating disorder treatment. Core symptoms of eating disorders were measured via self-report questionnaires. In particular, women with BED and BN showed similar patterns of core symptomatology compared with AN. However, when body mass index (BMI) was considered in the analyses, there were no differences between the three diagnostic groups in relation to body image. Differences in eating behavior are not solely triggered by weight differences, whereas body image disturbances are a transdiagnostic phenomenon among EDs and should also be considered in the treatment of BED.

Abstract
Whereas the manifestation of body image disturbance in binge eating disorder (BED) has been intensively investigated concerning the cognitive-affective component, with regard to the behavioral and the perceptual components of body image disturbance in BED, research is limited and results are inconsistent. Therefore, the present study assessed body image disturbance in BED with respect to the different components of body image in a sample of obese females (n = 31) with BED compared to obese females without an eating disorder (n = 28). The Eating Disorder Inventory-2, the Eating Disorder Examination-Questionnaire, the Body Image Avoidance Questionnaire and the Body Checking Questionnaire as well as a Digital Photo Distortion Technique based on a picture of each participant taken under standardized conditions were employed. Using two-sample t tests, we found that the participants with BED displayed significantly greater impairments concerning the cognitive-affective component of body image than the control group. Concerning the behavioral component, participants with BED reported more body checking and avoidance behavior than the controls, but group differences failed to reach significance after the Bonferroni corrections. Regarding the perceptual component, a significant group difference was found for the perceived "ideal" figure, with the individuals suffering from BED displaying a greater wish for a slimmer ideal figure than the control group. These results support the assumption that body image disturbance is a relevant factor in BED, similar to other eating disorders.

Abstract
The right temporoparietal cortex plays a critical role in body representation. Here, we applied repetitive transcranial magnetic stimulation (rTMS) over right extrastriate body area (EBA) and temporoparietal junction (TPJ) to investigate their causative roles in perceptual representations of one's own and others' body. Healthy women adjusted size-distorted pictures of their own body or of the body of another person according to how they perceived the body (subjective task) or how others perceived it (intersubjective task). In keeping with previous reports, at baseline, we found an overall underestimation of body size. Crucially, EBA-rTMS increased the underestimation bias when participants adjusted the images according to how others perceived their own or the other woman's body, suggesting a specific role of EBA in allocentric body representations. Conversely, TPJ-rTMS increased the underestimation bias when participants adjusted the body of another person, either a familiar other or a close friend, in both subjective and intersubjective tasks, suggesting an involvement of TPJ in representing others' bodies. These effects were body-specific, since no TMS-induced modulation was observed when participants judged a familiar object. The results suggest that right EBA and TPJ play active and complementary roles in the complex interaction between the perceptions of one's own and other people's body.

Abstract
Background Body image distortion is highly prevalent among overweight individuals. Whilst there is evidence that body-dissatisfied women and those suffering from disordered eating show a negative attentional bias towards their own unattractive body parts and others’ attractive body parts, little is known about visual attention patterns in the area of obesity and with respect to males. Since eating disorders and obesity share common features in terms of distorted body image and body dissatisfaction, the aim of this study was to examine whether overweight men and women show a similar attentional bias. Methods/Design We analyzed eye movements in 30 overweight individuals (18 females) and 28 normal-weight individuals (16 females) with respect to the participants’ own pictures as well as gender- and BMI-matched control pictures (front and back view). Additionally, we assessed body image and disordered eating using validated questionnaires. Discussion The overweight sample rated their own body as less attractive and showed a more disturbed body image. Contrary to our assumptions, they focused significantly longer on attractive compared to unattractive regions of both their own and the control body. For one’s own body, this was more pronounced for women. A higher weight status and more frequent body checking predicted attentional bias towards attractive body parts. We found that overweight adults exhibit an unexpected and stable pattern of selective attention, with a distinctive focus on their own attractive body regions despite higher levels of body dissatisfaction. This positive attentional bias may either be an indicator of a more pronounced pattern of attentional avoidance or a self-enhancing strategy. Further research is warranted to clarify these results.

Abstract
Obese people׳s distortions in visually-based mental body-parts representations have been reported in previous studies, but other sensory modalities have largely been neglected. In the present study, we investigated possible differences in tactilely-based body-parts representation between an obese and a healthy-weight group; additionally we explore the possible relationship between the tactile- and the visually-based body representation. Participants were asked to estimate the distance between two tactile stimuli that were simultaneously administered on the arm or on the abdomen, in the absence of visual input. The visually-based body-parts representation was investigated by a visual imagery method in which subjects were instructed to compare the horizontal extension of body part pairs. According to the results, the obese participants overestimated the size of the tactilely-perceived distances more than the healthy-weight group when the arm, and not the abdomen, was stimulated. Moreover, they reported a lower level of accuracy than did the healthy-weight group when estimating horizontal distances relative to their bodies, confirming an inappropriate visually-based mental body representation. Our results imply that body representation disturbance in obese people is not limited to the visual mental domain, but it spreads to the tactilely perceived distances. The inaccuracy was not a generalized tendency but was body-part related.

Abstract
Living in an ‘obesogenic’ environment poses a serious challenge for weight maintenance. However, many people are able to maintain a healthy weight indicating that not everybody is equally susceptible to the temptations of this food environment. The way in which someone perceives and reacts to food cues, that is, cognitive processes, could underlie differences in susceptibility. An attention bias for food could be such a cognitive factor that contributes to overeating. However, an attention bias for food has also been implicated with restrained eating and eating-disorder symptomatology. The primary aim of the present review was to determine whether an attention bias for food is specifically related to obesity while also reviewing evidence for attention biases in eating-disorder patients, restrained eaters and healthy-weight individuals. Another aim was to systematically examine how selective attention for food relates (causally) to eating behaviour. Current empirical evidence on attention bias for food within obese samples, eating-disorder patients, and, even though to a lesser extent, in restrained eaters is contradictory. However, present experimental studies provide relatively consistent evidence that an attention bias for food contributes to subsequent food intake. This review highlights the need to distinguish not only between different (temporal) attention bias components, but also to take different motivations (craving v. worry) and their impact on attentional processing into account. Overall, the current state of research suggests that biased attention could be one important cognitive mechanism by which the food environment tempts us into overeating.

Abstract
Purpose
– The purpose of this paper is to assess multidimensional body image concerns in a sample of obese women seeking bariatric surgery at an outpatient hospital clinic in Hamilton, Ontario, Canada.
Design/methodology/approach
– A sample of obese adult women seeking bariatric surgery at an outpatient medical clinic in Hamilton, Ontario, Canada (n=148) completed various self-report measures of body image concerns, including body image dysphoria, body image quality of life, body image investment, and appearance satisfaction. Participant scores were compared to normative data. Correlations between body image concern measures and body mass index (BMI) were examined.
Findings
– Participants endorsed more body image dysphoria, more negative body image quality of life, and less appearance satisfaction than normative samples. BMI was not correlated with body image concern scores.
Practical implications
– Interventions aimed at reducing body image disturbance in obese women should target multiple components of body image concern. Decisions about who should receive interventions should not be based on BMI status.
Originality/value
– The majority of research on body image concerns focuses exclusively on evaluative constructs such as body image dissatisfaction. The current study examined affective, cognitive, and behavioural body image constructs. A better understanding of the multidimensional nature of body image concerns in obese women seeking bariatric surgery informs the development of effective, targeted interventions.

Abstract
INTRODUCTION We compared the binge eating pathway linking body image dissatisfaction (BID) and psychological distress of obese adults entering and not entering psychological treatment for their weight problems. METHOD 90 obese participants seeking an integrated treatment (OB-IT) and 87 obese participants seeking only medical treatment (OB-MT) for their weight problems completed questionnaires on BID, binge eating and psychological well-being. RESULTS Only in the OB-IT group, binge eating behaviors mediated the relationship between BID and psychological distress. CONCLUSIONS Both BID and binge eating behaviors need to be addressed in the psychological and medical treatment for obesity to enhance psychological well-being.

Abstract
Patients with anorexia nervosa (AN) suffer from severe disturbances of body perception. It is unclear, however, whether such disturbances are linked to specific alterations in the processing of body configurations with respect to the local processing of body part details. Here, we compared a consecutive sample of 12 AN patients with a group of 12 age-, gender- and education-matched controls using an inversion effect paradigm requiring the visual discrimination of upright and inverted pictures of whole bodies, faces and objects. The AN patients presented selective deficits in the discrimination of upright body stimuli, which requires configural processing. Conversely, patients and controls showed comparable abilities in the discrimination of inverted bodies, which involves only detail-based processing, and in the discrimination of both upright and inverted faces and objects. Importantly, the body inversion effect negatively correlated with the persistence scores at the Temperament and Character Inventory, which evaluates increased tendency to convert a signal of punishment into a signal of reinforcement. These results suggest that the deficits of configural processing in AN patients may be associated with their obsessive worries about body appearance and to the excessive attention to details that characterizes their general perceptual style.

Abstract
OBJECTIVE Body dysmorphic disorder (BDD) is a relatively common psychiatric disorder characterized by preoccupations with perceived defects in physical appearance. This review aimed to explore epidemiology, clinical features, comorbidities, and treatment options for BDD in different clinical settings. DATA SOURCE AND STUDY SELECTION A search of the literature from 1970 to 2011 was performed using the MEDLINE search engine. English-language articles, with no restriction regarding the type of articles, were identified using the search terms body dysmorphic disorder, body dysmorphic disorder clinical settings, body dysmorphic disorder treatment, and body dysmorphic disorder & psychodermatology. RESULTS BDD occurs in 0.7% to 2.4% of community samples and 13% of psychiatric inpatients. Etiology is multifactorial, with recent findings indicating deficits in visual information processing. There is considerable overlap between BDD and obsessive-compulsive disorder (OCD) in symptom etiology and response to treatment, which has led to suggestions that BDD can be classified with anxiety disorders and OCD. A recent finding indicated genetic overlap between BDD and OCD. Over 60% of patients with BDD had a lifetime anxiety disorder, and 38% had social phobia, which tends to predate the onset of BDD. Studies reported a high level of comorbidity with depression and social phobia occurring in > 70% of patients with BDD. Individuals with BDD present frequently to dermatologists (about 9%-14% of dermatologic patients have BDD). BDD co-occurs with pathological skin picking in 26%-45% of cases. BDD currently has 2 variants: delusional and nondelusional, and both variants respond similarly to serotonin reuptake inhibitors (SRIs), which may have effect on obsessive thoughts and rituals. Cognitive-behavioral therapy has the best established treatment results. CONCLUSIONS A considerable overlap exists between BDD and other psychiatric disorders such as OCD, anxiety, and delusional disorder, and this comorbidity should be considered in evaluation, management, and long-term follow-up of the disorder. Individuals with BDD usually consult dermatologists and cosmetic surgeons rather than psychiatrists. Collaboration between different specialties (such as primary care, dermatology, cosmetic surgery, and psychiatry) is required for better treatment outcome.

Abstract
OBJECTIVE Disturbance of body perception is a central aspect of anorexia nervosa (AN) and several neuroimaging studies have documented structural and functional alterations of occipito-temporal cortices involved in visual body processing. However, it is unclear whether these perceptual deficits involve more basic aspects of others' body perception. METHOD A consecutive sample of 15 adolescent patients with AN were compared with a group of 15 age- and gender-matched controls in delayed matching to sample tasks requiring the visual discrimination of the form or of the action of others' body. RESULTS Patients showed better visual discrimination performance than controls in detail-based processing of body forms but not of body actions, which positively correlated with their increased tendency to convert a signal of punishment into a signal of reinforcement (higher persistence scores). DISCUSSION The paradoxical advantage of patients with AN in detail-based body processing may be associated to their tendency to routinely explore body parts as a consequence of their obsessive worries about body appearance.
