Abstract
It has been argued that high restrained eaters (i.e., people who fluctuate between restrictive food intake and overeating) are characterised by a heightened attentional bias to high calorie foods. However, the validity of this hypothesis has not yet been convincingly established. The current study sought to empirically evaluate this hypothesis using two directional measures of attentional bias: the well-established dot probe bias assessment task and the more novel Chase the Food bias assessment task. The latter attentional assessment approach has the capacity to differentiate between attentional switching and attentional maintenance within a complex and dynamic food environment. Participants (61 high restrained eaters and 38 low restrained eaters) completed the dot probe task and the Chase the Food task. Findings obtained on the dot probe task did not reveal a group difference in terms of biased attentional responding towards high calorie vs. low calorie food. Conversely, the two groups were found to differ on one of the measures obtained on the Chase the Food task. Specifically, high restrained eaters, as compared to low restrained eaters, demonstrated speeded attentional switching to high calorie foods, rather than a greater ability to maintain attention on high calorie foods when required to do so. These novel findings imply that high restrained eaters are potentially characterised by facilitated attentional switching towards high calorie foods. Implications are discussed including the possibility of targeting biased attentional switching using training variants of the Chase the Food task in interventions designed to reduce maladaptive eating behaviours.

Abstract
Attentional bias to low-fat bodies is thought to be associated with body dissatisfaction-a symptom and risk factor of eating disorders. However, the causal nature of this relationship is unclear. In three preregistered experiments, we trained 370 women to attend towards either high- or low-fat body stimuli using an attention training dot probe task. For each experiment, we analysed the effect of the attention training on (i) attention to subsequently presented high- versus low-fat body stimuli, (ii) visual adaptation to body size, and (iii) body dissatisfaction. The attention training had no effect on attention towards high- or low-fat bodies in an online setting (Experiment 1), but did increase attention to high-fat bodies in a laboratory setting (Experiment 2). Neither perceptions of a 'normal' body size nor levels of body dissatisfaction changed as a result of the attention training in either setting. The results in the online setting did not change when we reduced the stimulus onset-asynchrony of the dot probe task from 500 to 100 ms (Experiment 3). Our results provide no evidence that the dot probe training task used here has robust effects on attention to body size, body image disturbance or body dissatisfaction.

Abstract
Previous research provides evidence of maternally transmitted body-related attentional biases in female adolescents. In contrast, it remains unclear whether a familial transmission of body-related attentional biases also exists within father-son dyads. Therefore, the current study examined n = 42 male adolescents and their fathers with respect to direct and indirect paternal influences on body-related attention patterns and specific body-related concerns in sons. Besides completing specific body image questionnaires, participants were shown pictures of their own and a respective peer’s body, while their eye movements were tracked. The fathers additionally viewed the body pictures of their own son and an adolescent peer. Contrary to the assumed direct and indirect paternal transmission processes, the sons’ body-related attention patterns were not significantly associated with the perceived amount of paternal body-related feedback, with the fathers’ attention patterns towards their own son’s and the adolescent peer’s body, or with the fathers’ attention patterns towards their own and the adult peer’s body. Similarly, no significant associations were found between direct or indirect paternal influences and the sons’ drives for muscularity and thinness, body dissatisfaction, and muscularity-related body-checking behavior. Comparing the present findings with previous research indicating a maternal transmission of body-related attentional biases and body-related concerns in female adolescents, alternative (not gender-linked) familial transmission processes, e.g., via one’s own mother, or a comparatively higher relevance of other sociocultural influences, e.g., via peers or the media, might be assumed for male adolescents.

Abstract
OBJECTIVE Body and food-related information are thought to activate cognitive biases and contribute to the maintenance of eating disorders (ED). Approach-avoidance biases may play an important role in the maintenance of dietary restriction and excessive food intake. Therefore, the present study aimed to examine approach-avoidance biases toward food and body stimuli in individuals with anorexia nervosa (AN), bulimia nervosa (BN), and healthy controls (HC). METHODS The study included 42 individuals with AN, 24 individuals with BN, and 38 HCs. We used two implicit Approach-Avoidance Tasks (AAT) to assess approach-avoidance biases: participants completed a Food-AAT (high-calorie vs. low-calorie food) and a Body-AAT (thin vs. normal weight bodies). Additionally, explicit ratings of food and body stimuli were assessed. RESULTS There were no significant Group × Stimulus × Direction interactions in the implicit Food-AAT or implicit Body-AAT. In explicit ratings, individuals with AN and BN reported less urge to eat and more regret if they ate high-calorie and low-calorie food; individuals with AN and BN rated normal weight bodies as less normal weight, less attractive and less desirable than HCs. There were no group differences in explicit ratings of the thin body. DISCUSSION We did not find evidence for biased approach-avoidance tendencies toward food or body stimuli in individuals with AN or BN. Future studies are necessary to understand conflicting findings regarding approach-avoidance biases toward food and body stimuli in individuals with ED.

Abstract
BACKGROUND The present study examines the relationship between obesity, executive functions, and body image in a nonclinical population from southern Italy. METHODS General executive functioning (Frontal Assessment Battery-15), and body image disturbances (Body Uneasiness Test) were assessed in a sample including 255 participants (138 females, M age = 43.51 years, SD = 17.94, range = 18-86 years; M body mass index (BMI) = 26.21, SD = 4.32, range = 18.03-38.79). FINDINGS Multiple Linear Regression Analysis indicated that age, years of education, FAB15 score, body image concerns, and avoidance predicted the variance of BMI. A subsequent mediation analysis highlighted that the indirect effect of FAB15 on BMI through avoidance was statistically significant. INTERPRETATION Our results suggest that more performing executive functioning predicts a decrease in BMI that is partially due to the mitigation of avoidance behaviors.

Abstract
Selective processing of female thin-ideal body imagery is associated with greater body dissatisfaction, and eating disorder-specific rumination has been shown to mediate this relationship. Across two studies, we employed a modified rapid serial visual presentation task (similar to that used within the emotion-induced blindness literature), such that participants searched for a task-relevant target that was sometimes preceded by a thin body, non-thin body, or neutral task-irrelevant distractor. Our first experiment (N = 372) revealed a "body-induced blindness" in an unselected female sample, such that bodies in general distracted attention more than neutral images, and non-thin bodies distracted more than thin-ideal bodies. In our second experiment, female participants were selected based on eating disorder symptomatology (N = 114). Females that exhibited elevated eating disorder symptoms were distracted more by thin bodies compared to those low in symptomatology, greater distraction from thin bodies was associated with greater body dissatisfaction, and this relationship was mediated by eating disorder-specific rumination. Altogether, our findings illustrate the persistent nature of attentional distortions that occur early in cognitive processing and across time for those high in eating disorder symptomatology.

Abstract
OBJECTIVE This study is a secondary analysis testing the effects of an internet eating disorder prevention program on reward-based eating drive in a high-risk sample of college-aged women. METHOD We analyzed data from 278 women who were randomized to internet dissonance-based intervention (DBI-I), internet cognitive-behavioral treatment (CBTI), or no intervention (NI). Both active conditions consisted of self-guided activities completed over the course of four weeks. Linear mixed effects modeling was used to test the effect of internet intervention on reward-based eating drive. RESULTS DBI-I was associated with greater reductions in reward-based eating over time than NI. No other Condition × Time effects were found. DISCUSSION The results provide preliminary support for DBI-I as a strategy for reducing reward-based eating drive in a high-risk population relative to no intervention.

Abstract
The term Repulsive Body Image (RBI) refers to a schematic construct combining body-directed self-disgust and other negative body image features, that is assumed to bias information processing, including autobiographical memory retrieval. When specific memories about the own body are retrieved, intense self-disgust may arise and trigger urges to escape from those memories. We asked 133 women with high (HRBI; n = 63) and low (LRBI; n = 70) levels of habitual body-directed self-disgust to recall autobiographical memories in response to 11 concrete body-related cue words in a minimal instructions Autobiographical Memory Test (AMT). Despite an overall low level of memory specificity, we found that RBI levels were associated with stronger disgust reactions and stronger motivations to escape from body-related memories. In addition, disgust reactions to body-related memories accounted for the association between habitual levels of self-disgust and urges to escape from these memories. Thus, the findings indicated that women with body image concerns showed disgust-based urges to escape from body-related memories. This disgust-based urge to avert from body-related autobiographical memories might counteract the correction of an RBI, thereby contributing to the persistence of body image concerns and associated psychopathology.

Abstract
BACKGROUND Anorexia nervosa (AN) is characterized by dysfunctional cognitions including cognitive biases at various levels of information processing. However, less is known about the specificity of these biases, i.e., if they occur for eating-disorder-related information alone or also for non-eating-disorder-related emotional information in AN patients (content-specificity) and if they are unique to individuals with AN or are also shown by individuals with other mental disorders (disorder-specificity). METHODS The present study systematically assesses cognitive biases in 12-18-year-old female adolescents with AN on three levels of information processing (attention, interpretation, and memory) and with regard to two types of information content (eating-disorder-related, i.e., stimuli related to body weight and shape, and non-eating-disorder-related). To address not only content- but also disorder-specificity, adolescents with AN will be compared not only to a healthy control group but also to a clinical control group (adolescents with major depression or particular anxiety disorders). Cognitive biases are assessed within a single experimental paradigm based on the Scrambled Sentences Task. During the task eye movements are recorded in order to assess attention biases while interpretation biases are derived from the behavioural outcome. An incidental free recall test afterwards assesses memory biases. We expect adolescents with AN to show more pronounced negative cognitive biases on all three levels of information processing and for both types of content compared to healthy adolescents. In addition, we expect the specificity of biases to translate into differential results for the two types of content: AN patients are expected to show stronger biases for disorder-related stimuli but similar or less pronounced biases for non-disorder-related stimuli compared to the clinical control group. DISCUSSION This is the first study to comprehensively assess cognitive biases in adolescents with AN. It will have essential implications not only for cognitive-behavioural models of AN but also for subsequent studies aiming to modify cognitive biases in this population, thereby addressing important maintaining factors already at an early stage of the disorder.

Abstract
A number of psychiatric disorders, including body dysmorphic disorder (BDD), anorexia nervosa, bulimia nervosa, and social anxiety disorder, are characterized by heightened appearance concerns and increased cognitive and perceptual biases toward one’s own physical appearance. In the present study, we examined individual differences in self-reported appearance anxiety and symptoms of BDD in relation to the late positive potential (LPP)—an index of stimulus significance—in response to pictures of oneself, strangers and objects among 83 female college students. The results indicated that the LPP was larger for pictures of oneself compared to pictures of strangers and objects. Further, the Yale–Brown Obsessive-Compulsive Scale Modified for Body Dysmorphic Disorder and Appearance Anxiety Inventory scales both related to an increased LPP to pictures of oneself but not to strangers or objects. The findings suggest that the LPP elicited by pictures of oneself may function as a neural marker of appearance concerns, which could be leveraged to study the development and maintenance of a range of psychiatric disorders characterized by increased appearance concerns.

Abstract
Abstract
Background
Theoretical models emphasize the importance of implicit self-related weight attitudes for the maintenance of body dissatisfaction. Even though body dissatisfaction is increased in obesity, only general implicit weight-related attitudes have been investigated so far. Therefore, the present study assessed self-related and general implicit weight attitudes and their relation to food.
Methods
Women with overweight and obesity (OW; n = 71) and women with normal weight (NW; n = 44) completed three implicit tasks to (1) assess attitudes towards persons with normal weight and overweight in general, (2) attitudes towards one’s own body, and (3) the association between one’s own body and food.
Results
While both groups showed an implicit preference towards persons with normal weight relative to persons with overweight, only women with OW showed a significantly stronger negative implicit attitude towards their own body and a stronger association between food and one’s own body. Additionally, self-related and not general implicit weight attitudes correlated significantly with body dissatisfaction and eating pathology.
Conclusions
The results highlight the importance of self-related implicit attitudes and their relation to body dissatisfaction and eating pathology in women with overweight and obesity. Targeting these self-related implicit weight attitudes might help to improve obesity treatments.

Abstract
Background
Body image disturbance (BID) is a hallmark feature of eating disorders (EDs) and has proven to be involved in their etiology and maintenance. Therefore, the targeting of BID in treatment is crucial, and has been incorporated in various treatment manuals. One of the most common techniques in the treatment of BID is body exposure (BE), the confrontation with one’s own body. BE has been found to be effective in individuals with EDs or high body dissatisfaction. However, BE is applied in a multitude of ways, most of which are based on one or a combination of the hypothesized underlying working mechanisms, with no differential effectiveness known so far.
Method
The aim of this paper is to selectively review the main hypothesized working mechanisms of BE and their translation into therapeutic approaches.
Results and Conclusion
Specifically, we underline that studies are needed to pinpoint the proposed mechanisms and to develop an empirically informed theoretical model of BE. We provide a framework for future studies in order to identify working mechanisms and increase effectiveness of BE.

Abstract
AIM Food restriction is argued to be a precursor for unhealthy preoccupation with food, possibly leading to the development of an eating disorder. We updated previous meta-analyses that examined the relationship between eating restraint and deficits in either general or food-related attentional and inhibitory control. We hypothesized that inconsistencies in the literature around eating restraint, impaired cognitive control, impulsivity and cognitive biases for food could be attributed to the scale used to measure eating restraint. METHOD A (preregistered) subgroup meta-analysis examined whether patterns of impaired cognitive control and cognitive bias for food in predominantly healthy (non-clinical) samples differed as a function of the scale used to measure eating restraint. A series of exploratory meta-analyses were carried out for specific attentional bias tasks. In total 57 datasets were included. RESULTS The subgroup analysis did not provide evidence that the relationship between eating restraint and impaired or biased cognitions differed significantly as a function of restraint scale. Heterogeneity across studies was high. When examining specific attentional bias tasks there was no evidence that increased eating restraint was associated with increased attentional bias or distraction by food cues, regardless of which scale was used to measure eating restraint. CONCLUSIONS There is little experimental evidence for the common narrative that increased eating restraint is related to impaired cognitive control generally or increased cognitive bias for food, in non-clinical samples.

PLoS One 2021; 16:e0257303. [PMID: 34516591 PMCID: PMC8437269 DOI: 10.1371/journal.pone.0257303] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2020] [Accepted: 08/29/2021] [Indexed: 01/15/2023] Open
Abstract
Mirror exposure (ME) is an effective technique to improve body image. However, evidence on the underlying mechanisms and the optimal verbalization instruction during ME is lacking. Therefore, this experimental study analyzed mechanisms of ME and therapeutic outcomes by comparing positive (PV) and negative (NV) full-body verbalization. N = 73 healthy females were randomized to a PV or an NV condition. PV participants verbalized positively while NV participants verbalized negatively about their whole body. Each participant underwent three standardized ME sessions. Before and after each ME session, positive affect, negative affect and body satisfaction were assessed. Before the first and after the third ME, participants completed questionnaires on cognitive-affective and behavioral aspects of body image, eating pathology and self-esteem. Regarding within-ME changes, the results indicate that positive affect and body satisfaction decreased while negative affect increased in the NV group but not in the PV group. In contrast, regarding between-ME changes, decreased negative affect as well as positive affect and increased body satisfaction were observed in both groups. However, eating pathology remained stable, whereas body-checking behavior increased and the PV condition was followed by higher levels of self-esteem compared to the NV condition. These findings suggest that both PV and NV improve negative affect and body satisfaction between-ME, and thus seem to be effective ME instructions. Given that NV led to increased negative affect within-ME and did not influence self-esteem, PV might represent the favorable instruction during ME for body-satisfied women.

Abstract
OBJECTIVES Previous mindful eating scales stress the attentional domains of eating-specific mindfulness, such as present-moment attention to homeostatic cues of hunger and satiety while discounting other important domains such as non-judgment and decentering. The purpose of the series of studies was to develop and evaluate a multifaceted mindful eating scale that assesses several domains of eating-specific mindfulness. METHODS A multistep process was used to construct the Four Facet Mindful Eating Scale (FFaMES). Study 1 outlined the initial scale construction and the development of a novel item pool (N = 480). Study 2 examined the internal structure of the observed variables using exploratory analysis (N = 445) and confirmatory analysis in a separate sample (N = 445). Reliability and validity were assessed in Study 3 (N = 166). RESULTS The final scale consists of 29 items with 4 factors: Non-Reactance, Non-Judgment, External Awareness, and Internal Awareness. The FFaMES demonstrated good internal consistency, retest reliability as well as preliminary convergent and divergent validity. CONCLUSIONS Our findings provide reliability evidence and initial support for the construct validity of the FFaMES and the continued study of multiple facets of eating-specific mindfulness. Future research should continue to investigate the differential effects of various aspects of eating-specific mindfulness in the prevention and treatment of obesity and its comorbidities.

Abstract
Body checking is a repeated behavior conducted in an attempt to gain information about one's shape, weight, size, or body composition. Body checking is associated with negative behavioral, emotional, and cognitive outcomes and may maintain body dissatisfaction and eating disorders. The precise function and consequences of body checking remain less well understood. Specifically, immediate and delayed impacts of repeated critical body checking (CBC) have not been determined. The current study randomly assigned 142 young women with high shape/weight concern to daily 10-min CBC, neutral body checking (NBC), or a non-body critical checking (NBCC) comparison condition, examining their immediate and delayed (one-week follow-up) effects on body satisfaction, self-esteem, and negative affect. Multilevel modeling and follow-up planned comparisons found that compared to NBCC, CBC participants' body satisfaction and self-esteem immediately decreased, but negative affect improved from baseline to follow-up. Compared to CBC, NBC participants' self-esteem and negative affect improved immediately, and their self-esteem improved over time compared to NBCC. Over time, all participants' state body satisfaction improved, regardless of condition. Our findings suggest a 10-min CBC session may function differently than typical (harmful) in vivo body checking. However, reasons for this difference are unclear. Additional research is needed to distinguish (harmful) in vivo body checking from CBC procedures such as this and other mirror exposure interventions. Research is needed to examine the effects of varying CBC duration and instructions during body exposure to further clarify mechanisms of change during body exposures.

Abstract
Body image concerns revolving around body ideals (thin ideal, muscular ideal) are widespread among women. Whereas a stronger preoccupation with ideal physical appearance is often assumed for narcissistic women, previous empirical findings have been mixed. Following a tripartite structure of agentic, antagonistic, and neurotic narcissism facets, we reexamined whether trait narcissism predicted drive for thinness and drive for muscularity. We further explored the role of importance of appearance as a mediator and moderator of the relation between narcissism and body image concerns. Latent structural equation modeling was applied to self-report data from two independent nonclinical female samples (NSample1 = 224, NSample2 = 342). Results underlined the importance of distinguishing between narcissism facets: Neurotic (but not agentic or antagonistic) narcissism uniquely predicted drive for thinness and drive for muscularity. Importance of appearance mediated but did not robustly moderate these relations. Hence, neurotic narcissistic women (characterized by hypersensitivity, shame, and a fragile self-esteem) are particularly prone to body image concerns. This vulnerability seems partly driven by how much importance they ascribe to their appearance. Future work might build on these insights to further unravel the processes linking neurotic narcissism to body image concerns and how these can be targeted in practical interventions.

Abstract
Caloric restriction (CR) is a strategy that attenuates aging in multiple nonhuman species. The Comprehensive Assessment of Long-term Effects of Reducing Intake of Energy (CALERIE) trials are part of a research program aiming to test the effects of CR on aging and longevity biomarkers in humans. Building on CALERIE phase 1, CALERIE phase 2 (CALERIE 2) was the largest study to date to assess sustained CR in healthy humans without obesity. In a 24-month randomized controlled trial comprising 218 participants at baseline, CALERIE 2 showed that moderate CR, 11.9% on average, induced improvements in aging-related biomarkers without adversely affecting psychological or behavioral outcomes. The objectives of this report are to summarize and review the highlights of CALERIE 2 and report previously unpublished results on eating disorder symptoms and cognitive function. This article specifically summarizes the physiological, psychological, aging, behavioral, and safety results of the trial. Also provided are research directions beyond CALERIE 2 that highlight important opportunities to investigate the role of CR in aging, longevity, and health span in humans.

Abstract
Over the last 25 years, virtual reality (VR) has offered innovative solutions for targeting different key symptoms of eating disorders: from craving to negative emotions, from attentional biases to body dissatisfaction. The present narrative review assesses the existing literature in these areas trying to identify their different levels of clinical evidence. Specifically, the review presents four clinical approaches based upon VR and their implications in the treatment of eating disorders: VR cue exposure, VR reference frame shifting, VR for correcting body distortions and attentional biases. In general, existing findings demonstrate the clinical value of VR. On one side, the present review suggests that two VR-based techniques-VR exposure and reference frame shifting-have a significant research support and provide a possible advantage over traditional cognitive-behavioural therapy (CBT) for bulimia nervosa and binge eating disorder. On the other side, two emerging VR applications-multisensory body illusions and the use of VR for the modification of attentional biases-even if supported by preliminary data still need further research.

Abstract
OBJECTIVE Besides all visible somatic manifestations, distorted body representation is a key symptom for anorexia nervosa (AN). Body representation can be divided into a conscious component, body image, and an unconscious action-related one, body schema. As behavioral studies already explored the impact of a distorted body image in AN, we aimed to explore whether distortion also extends into unconscious body schema. This study is the first with an unbiased measurement of the body schema in a homogeneous sample of AN patients. METHOD Twenty-three patients diagnosed with AN and 23 healthy controls (HC) walked through a door like aperture varying in width. Door width was based on participants shoulder width and ranged from an aperture-to-shoulder-ratio of (A/S) 0.9 to 1.45. Shoulder rotation was measured as indication of perceived body width. To measure the unconscious body schema, we used a cover story pretending to investigate the influence of change of position on retention memory. RESULTS We found a significantly higher critical A/S for AN than HC, which indicates that AN patients rotate their shoulders for relatively larger door widths than HC, thus unconsciously estimating their body size to be larger than in reality. Additionally, we found a correlation between negative body attribution and overestimation of bodily dimensions. DISCUSSION As stated by the "allocentric-lock"-hypothesis, AN patients might be locked to a stored representation of their body that cannot be updated and remains at pre-AN conditions. We suggest future AN-therapy to counter body schema alterations by combining cognitive behavioral therapy and virtual reality therapy.

Abstract
Background: Although previous studies have shown an inverse relation between life meaning and eating disorder symptoms, the correlational nature of this evidence precludes causal inferences. Therefore, this study used an experimental approach to test the causal impact of life meaning on individuals' weight and shape concerns. Methods: Female students at risk for developing an eating disorder (N = 128) were randomly assigned to the control or the meaning condition, which involved thinking about and committing to pursue intrinsically valued life goals. A color-naming interference task was used to assess the motivational salience of body-related stimuli, and self-report measures were used to assess participants' overvaluation of weight and shape. Results: The meaning manipulation was effective in activating intrinsically valued life goals. However, it did not result in lower self-reported overvaluation of weight and shape or lower color-naming interference effects of body-related stimuli, compared to the control condition. Post-hoc analyses suggested that baseline meaning in life was related to the impact of the manipulation. Conclusions: This experimental study did not provide evidence for a causal influence of life meaning on the overvaluation of weight and shape in a high-risk group. The current findings suggest that we first need to examine the relationship between life meaning and eating disorder symptoms in more detail, before implementing brief meaning manipulations in clinical practice.

Abstract
Since its publication in 1950, the Biology of Human Starvation, which describes the classic longitudinal Minnesota Experiment of semistarvation and refeeding in healthy young men, has been the undisputed source of scientific reference about the impact of long-term food deprivation on human physiology and behavior. It has been a guide in developing famine and refugee relief programs for international agencies, in exploring the effects of food deprivation on the cognitive and social functioning of those with anorexia nervosa and bulimia nervosa, and in gaining insights into metabolic adaptations that undermine obesity therapy and cachexia rehabilitation. In more recent decades, the application of a systems approach to the analysis of its data on longitudinal changes in body composition, basal metabolic rate, and food intake during the 24 weeks of semistarvation and 20 weeks of refeeding has provided rare insights into the multitude of control systems that govern the regulation of body composition during weight regain. These have underscored an internal (autoregulatory) control of lean-fat partitioning (highly sensitive to initial adiposity), which operates during weight loss and weight regain and revealed the existence of feedback loops between changes in body composition and the control of food intake and adaptive thermogenesis for the purpose of accelerating the recovery of fat mass and fat-free mass. This paper highlights the general features and design of this grueling experiment of simulated famine that has allowed the unmasking of fundamental control systems in human body composition autoregulation. The integration of its outcomes constitutes the "famine reactions" that drive the normal physiology of weight regain and obesity relapse and provides a mechanistic "autoregulation-based" explanation of how dieting and weight cycling, transition to sedentarity, or developmental programming may predispose to obesity. It also provides a system physiology framework for research toward elucidating proteinstatic and adipostatic mechanisms that control hunger-appetite and adaptive thermogenesis, with major implications for a better understanding (and management) of cachexia, obesity, and cardiometabolic diseases.

Abstract
OBJECTIVE Low satisfaction with normative life domains might be an important factor in the persistence of anorexia nervosa (AN). Initial evidence in non-clinical samples showed that lower satisfaction with normative life domains was related to more intense eating disorder symptoms. As a critical next step, the current study examined satisfaction with normative life domains in a clinical sample. Specifically, the present study tested whether adolescents with AN reported lower satisfaction with normative life domains than adolescents without an eating disorder. METHOD Adolescents with AN (n = 69) and adolescents without an eating disorder matched on age, gender and educational level (n = 69) completed the Brief Multidimensional Students' Life Satisfaction Scale to assess satisfaction with five life domains (family, friendships, school, self and living location) and life in general. RESULTS Adolescents with AN reported significantly lower satisfaction with normative life domains than the comparison group. Subsequent analyses showed that this overall group difference was primarily driven by adolescents with AN reporting lower satisfaction with the self, school experience and life in general. CONCLUSIONS Findings supported the hypothesis that adolescents with AN show relatively low satisfaction with meaningful, non-AN-related life domains. This points to the potential relevance of enhancing satisfaction with specific life domains to optimize treatment effectiveness.

Abstract
BACKGROUND Fear of weight gain is a characteristic feature of anorexia nervosa (AN), and reducing this fear is often a main target of treatment. However, research shows that 20% of individuals with AN do not report fear of weight gain. Studies are needed that evaluate the centrality of fear of weight gain for AN with a method less susceptible to deception than self-report. METHODS We approximated implicit fear of weight gain by measuring implicit drive for thinness using implicit association tests (IATs). We asked 64 participants (35 AN, 29 healthy controls [HCs]) to categorize statements as pro-dieting vs. non-dieting and true vs. false in a questionnaire-based IAT, and pictures of underweight vs. normal-weight models and positive vs. negative words in a picture-based IAT using two response keys. We tested for associations between implicit drive for thinness and explicitly reported psychopathology within AN as well as group differences between AN and HC groups. RESULTS Correlation analyses within the AN group showed that higher implicit drive for thinness was associated with more pronounced eating disorder-specific psychopathology. Furthermore, the AN group showed a stronger implicit drive for thinness than HCs in both IATs. CONCLUSION The results highlight the relevance of considering fear of weight gain as a continuous construct. Our implicit assessment captures various degrees of fear of weight gain in AN, which might allow for more individually tailored interventions in the future.

AN-VR-BE. A Randomized Controlled Trial for Reducing Fear of Gaining Weight and Other Eating Disorder Symptoms in Anorexia Nervosa through Virtual Reality-Based Body Exposure. J Clin Med 2021; 10:jcm10040682. [PMID: 33578767 PMCID: PMC7916489 DOI: 10.3390/jcm10040682] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Revised: 02/03/2021] [Accepted: 02/07/2021] [Indexed: 12/18/2022] Open
Abstract
In vivo body exposure therapy is considered an effective and suitable intervention to help patients with anorexia nervosa (AN) reduce their body image disturbances (BIDs). However, these interventions have notable limitations and cannot effectively reproduce certain fears usually found in AN, such as the fear of gaining weight (FGW). The latest developments in virtual reality (VR) technology and embodiment-based procedures could overcome these limitations and allow AN patients to confront their FGW and BIDs. This study aimed to provide further evidence of the efficacy of an enhanced (by means of embodiment) VR-based body exposure therapy for the treatment of AN. Thirty-five AN patients (16 in the experimental group, 19 in the control group) participated in the study. FGW, BIDs, and other body-related and ED measures were assessed before and after the intervention and three months later. The experimental group received treatment as usual (TAU) and five additional sessions of VR-based body exposure therapy, while the control group received only TAU. After the intervention, ED symptoms were clearly reduced in both groups, with most of the changes being more noticeable in the experimental group. Specifically, after the intervention and at follow-up, significant group differences were found in the FGW and BIDs, with the experimental group showing significantly lower values than the control group. The current study provides new insights and encouraging findings in the field of exposure-based therapies in AN. VR technology might improve research and clinical practice in AN by providing new tools to help patients confront their core fears (i.e., food- or weight-related cues) and improve their emotional, cognitive, and behavioral responses to their body image.

Abstract
BACKGROUND Foraging tasks have recently been increasingly used to investigate visual attention. Visual attention can be biased when certain stimuli capture our attention, especially threatening or anxiety-provoking stimuli, but such effects have not been addressed in foraging studies. METHODS We measured potential attentional bias associated with eating disorder symptoms to food related stimuli with our previously developed iPad foraging task. Forty-four participants performed a foraging task where they were instructed to tap predesignated food related targets (healthy and unhealthy) and other non-food objects and completed four self-report questionnaires measuring symptoms of eating disorders. Participants were split into two groups based on their questionnaire scores, a symptom group and no symptom group. RESULTS The foraging results suggest that there are differences between the groups on switch costs and target selection times (intertarget times) but they were only statistically significant when extreme-group analyses (EGA) were used. There were also notable food versus non-food category effects in the foraging patterns. CONCLUSIONS The results suggest that foraging tasks of this sort can be used to assess attentional biases and we also speculate that they may eventually be used to treat them through attention bias modification. Additionally, the category effects that we see between food items and other items are highly interesting and encouraging. At the same time, task sensitivity will need to be improved. Finally, future tests of clinical samples could provide a clearer picture of the effects of eating disorder symptoms on foraging for food.

Abstract
Episodic memory is typically thought of as the memory system that makes possible mental time travel through subjective time. This may serve an important function in allowing us to use recent dietary information to predict future food needs and integrate this information with current food availability to adapt motivation accordingly. Growing evidence has suggested that episodic memory influences and is influenced by obesity. However, there is limited available evidence on the characteristics of episodic memory for food and non-food cues in people with obesity. The present study attempts to address this association and apply an episodic memory task to evaluate item memory and source memory for food and non-food cues in females with obesity. Participants were 26 females with obesity and 30 females with healthy weight, who were undergraduate students aged 17-24 years. They completed the Dutch Eating Behavior Questionnaire, hunger visual analog scale, fullness visual analog scale, desire-to-eat visual analog scale, and an episodic memory task including item memory and source memory. Results showed that the episodic memory patterns of females with and without obesity changed according to the type of stimuli. Specifically, females with obesity outperformed females with healthy weight in item memory for food cues, but showed deficits in item memory for non-food cues and source memory for both food and non-food cues. Taken together, based on the obesity and suboptimal food-related decision theoretical model, these findings are of great theoretical and clinical significance to explore episodic memory pattern differences between people with and without obesity.

Front Psychiatry 2021; 12:795189. [PMID: 35095608 PMCID: PMC8792988 DOI: 10.3389/fpsyt.2021.795189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2021] [Accepted: 12/10/2021] [Indexed: 11/29/2022] Open
Abstract
Body checking (BC) is not only inherent to the maintenance of eating disorders but is also widespread among healthy females. According to etiological models, while BC serves as an affect-regulating behavior in the short term, in the longer term it is assumed to be disorder-maintaining and also produces more negative affect. The present study therefore aimed to empirically examine the proposed longer-term consequences of increased BC. In an online study, N = 167 women tracked their daily amount of BC over a total of 7 days: Following a 1-day baseline assessment of typical BC, participants were asked to check their bodies in an typical manner for 3 days and with a 3-fold increased frequency for 3-days. Before and after each BC episode, the impact of BC on affect, eating disorder symptoms, general pathology and endorsement of different functions of BC was assessed. Participants showed longer-term consequences of increased BC in terms of increased negative affect and general pathology, while eating disorder symptoms remained unaffected. In the case of typical BC, participants showed decreased general pathology and anxiety. Furthermore, the endorsement of a higher number of BC functions led to increased negative affect and an increased amount of typical BC. The findings support the theoretically assumed role of maladaptive BC in maintaining negative emotion in the longer term. However, though requiring replication, our finding of positive effects of typical BC calls into question the overall dysfunctionality of BC among non-clinical women who are not at risk of developing an eating disorder.

Abstract
Early reports suggest that lockdown measures associated with the COVID-19 pandemic (e.g., social distancing) are having adverse consequences for people's mental health, including increases in maladaptive eating habits and body dissatisfaction. Certain groups, such as those with pre-existing mental health difficulties, may be especially at risk. The current study explored perceived changes in eating, exercise, and body image during lockdown within the United Kingdom, using an online survey (n = 264). There were large individual differences in perceived changes in eating, exercise, and body image in this period. Women were more likely than men to report increasing struggles with regulating eating, preoccupation with food and worsening body image. Those with a current/past diagnosis of eating disorders reported significantly greater difficulties in regulating eating, increased preoccupation with food, exercise thoughts and behaviours and concern about appearance, even when compared to those with other mental health and developmental disorders. Ongoing research to explore individual differences in the trajectories of change in eating, exercise and body image as lockdown measures ease will be important for understanding the full psychological impact of this pandemic and improve service and public health planning going forward.

Abstract
OBJECTIVES Previous studies found that low education or income level was associated with insufficient fruit and vegetable consumption (IFVC) among the general population. However, cancer survivors can be heterogeneous from the general population in many aspects. Our objective was to disentangle their association among cancer survivors. DESIGN Nationwide cross-sectional survey in the USA. SETTING 2017 Behaviour Risk Factor Surveillance System. PARTICIPANTS 5409 cancer survivors. EXPOSURE AND OUTCOME Educational level (graduated from college/technical school, attended college/technical school and high school or less) and annual household income (≥US$75 000, US$35 000 to <US$75 000 and <US$35 000) were exposures of interest. IFVC, which was defined as <5 servings/day according to the American Cancer Society recommendation, was treated as the outcome. DATA ANALYSIS Multivariable logistic regression corrected for sampling weight was performed to estimate the association. Subgroup analyses and interaction tests were performed by age, gender, obesity and physical activity. RESULTS Overall, 4750 survivors (weighted percentage: 88.5%) had IFVC. Participants with lower education had a significantly higher rate of IFVC (high school or less vs college graduates: adjusted OR=2.17, 95% CI 1.45 to 3.25, p trend <0.01). The association between income and IFVC was almost null. Associations did not differ in most subgroups; however, the association of lower education appeared to be more substantial among physically inactive survivors (p interaction <0.01). CONCLUSION Low educational background, not low income, was associated with IFVC among cancer survivors. Prospective cohort studies are needed to verify the conclusion.

Abstract
OBJECTIVE Attentional biases to stimuli related to stigmatized appearance are theorized to stem from appearance overvaluation, but little research has examined this link. As well, little research has examined whether appearance overvaluation is associated with biases toward stimuli that describe the attractiveness ideal. We addressed these gaps in the literature using the emotional Stroop task and tested whether appearance overvaluation is associated with an attentional bias for words that describe stigmatized appearance (e.g., fat, ugly, shabby), the attractiveness ideal (e.g., thin, beautiful, fashionable), or both. METHOD AND RESULTS In Study 1, a community sample of people (N = 86) completed measures of appearance overvaluation, body dissatisfaction, and body mass index (BMI) followed by an emotional Stroop task. Appearance overvaluation was associated with an attentional bias for attractiveness ideal words-not stigmatized appearance words. Results remained significant when controlling for participants' body dissatisfaction, BMI, and gender. Study 2 (N = 316) replicated these findings. Finally, an integrative data analysis that pooled the data of Studies 1 and 2 (N = 402) provided additional support for our general hypothesis that people who overvalue appearance display an attentional bias to stimuli related to the attractiveness ideal. DISCUSSION The results show a robust association between appearance overvaluation and selective attention for attractiveness ideal stimuli. Results are discussed in reference to theory and research on information processing in eating disorders. We also call for research to examine information processing of stimuli related to the attractiveness ideal among people with eating disorders and who place high importance on appearance for self-definition.

Abstract
OBJECTIVES Cognitive biases, particularly attentional biases, have been shown to be central to anorexia nervosa (AN). This study looked at attention deployment when consecutively viewing an obese and own body stimulus that both might represent feared stimuli in AN. METHODS Individuals with AN (n = 26) and mentally healthy controls (MHCs; n = 16) viewed a picture of themselves and a standardized computer-generated obese body in random order for 4,000 ms each and then rated the attractiveness of the body parts of both stimuli. We compared dwell times on subjectively unattractive versus attractive body parts, and body parts that show weight status and gain most strongly (stomach, hips, thighs) versus least strongly. RESULTS For both stimuli, participants focused longer on the subjectively unattractive body parts (p < .01 and .001), with an even stronger attentional bias in individuals with AN regarding the obese stimulus (p < .05). Both groups also gazed longer at body parts indicative of weight status or gain (both stimuli p < .001), with no group differences. CONCLUSIONS The attentional bias to one's own subjectively unattractive body parts might represent a mechanism maintaining body image disturbance in women in general. This attentional bias is even stronger when women with AN are confronted with an obese stimulus, highlighting a potential mental preoccupation with being fat or weight gain and a behavior distinct for the disorder.

Abstract
Fear of gaining weight (FGW), body image disturbances, associated anxiety and body-related attentional bias are the core symptoms of anorexia nervosa (AN) and play critical roles in its development and maintenance. The aim of the current study is to evaluate the usefulness of virtual reality-based body exposure software for the assessment of important body-related cognitive and emotional responses in AN. Thirty female patients with AN, one of them subclinical, and 43 healthy college women, 25 with low body dissatisfaction (BD) and 18 with high BD, owned a virtual body that had their silhouette and body mass index. Full-body illusion (FBI) over the virtual body was induced using both visuo-motor and visuo-tactile stimulation. Once the FBI was induced, the FBI itself, FGW, body anxiety and body-related attentional bias toward weight-related and non-weight-related body areas were assessed. One-way analyses of covariance (ANCOVA), controlling for age, showed that AN patients reported higher FGW, body anxiety and body-related attentional bias than healthy controls. Unexpectedly, patients with AN reported significantly lower FBI levels than healthy participants. Finally, Pearson correlations showed significant relationships between visual analog scales and body-related attentional bias measures, compared to other eating disorder measures. These results provide evidence about the usefulness of virtual reality-based body exposure to elicit FGW and other body-related disturbances in AN patients. Thus, it may be a suitable intervention for reducing these emotional responses and for easing weight recovery.

Abstract
PURPOSE Numerous studies highlight the relevance of body image in the development and maintenance of overweight and obesity mostly using self-reported data. Given the importance of physiological assessment methods, the present study aimed at investigating vocally encoded emotional arousal as a correlate of body distress in women with overweight and obesity. METHODS Cognitions of women with overweight and obesity (OW; n = 22) as well as normal weight controls (NW; n = 22) were assessed by means of a thought-sampling procedure during a mirror exposure and a control condition. Fundamental frequency (f0) as a marker of vocally encoded emotional arousal as well as verbalized body-related cognitions were analyzed during this experimental task. RESULTS A stronger increase in f0 between the control and the mirror exposure condition was found in OW compared to NW. Furthermore, there were significant positive correlations between vocally encoded emotional arousal and various measures of body image. CONCLUSION The findings support the utility of vocally encoded emotional arousal as an objective physiological correlate of the evaluative dimension of body image in women with overweight and obesity. LEVEL OF EVIDENCE Level I, experimental study.

Abstract
How do individuals rank body shapes? Does this relate to the body part one is most dissatisfied with? Our study investigates whether one can generalize regarding how women represent the body. Three BMI-calibrated images from the Photographic Figure Rating Scale, representative of thin (BMI = 14.72), medium (BMI = 20.33), and large (BMI = 29.26) shapes, were divided into torso, legs and arms, and saved as individual images on a black background. Of 27 possible composite images, 8 were chosen based on a Torso (thin vs. large) × Leg (thin/large vs. medium) × Arm (thin vs. large) design. Our 44 female participants ordered these from thinnest to largest. This was first according to torso, then leg, and finally arm: 41 individuals agreed on the thinnest image (thin torso, thin legs, thin arms), followed by a second image (thin torso, thin legs, large arms, n = 26; or thin torso, medium legs, thin arms, n = 10). One participant differed markedly in her choice of the first image (large torso, medium legs, thin arms). Interestingly, she scored 10 on the EDI-2 scale of Bulimic Tendencies, revealing high risk for bulimia, suggesting that our task might be useful for studying eating disorders. Our juxtaposition of two analytic procedures-partial order scalogram analysis (POSAC) and cluster analysis-enables one to uncover such outliers in a data set. Importantly, the 2D POSAC space clearly reveals the hierarchical structure of the body image.

Abstract
Recent work using naturalistic, repeated, ambulatory assessment approaches have uncovered a range of within-person mood- and body image-related dynamics (such as fluctuation of mood and body dissatisfaction) that can prospectively predict eating disorder behaviors (e.g., a binge episode following an increase in negative mood). The prognostic significance of these state-based dynamics for predicting trait-level eating disorder severity, however, remains largely unexplored. The present study uses within-person relationships among state levels of negative mood, body image, and dieting as predictors of baseline, trait-level eating pathology, captured prior to a period of state-based data capture. Two-hundred and sixty women from the general population completed baseline measures of trait eating pathology and demographics, followed by a 7 to 10-day ecological momentary assessment phase comprising items measuring state body dissatisfaction, negative mood, upward appearance comparisons, and dietary restraint administered 6 times daily. Regression-based analyses showed that, in combination, state-based dynamics accounted for 34-43% variance explained in trait eating pathology, contingent on eating disorder symptom severity. Present findings highlight the viability of within-person, state-based dynamics as predictors of baseline trait-level disordered eating severity. Longitudinal testing is needed to determine whether these dynamics account for changes in disordered eating over time.

Body-Related Attentional Bias among Men with High and Low Muscularity Dissatisfaction. J Clin Med 2020; 9:jcm9061736. [PMID: 32512745 PMCID: PMC7355895 DOI: 10.3390/jcm9061736] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Revised: 05/26/2020] [Accepted: 06/02/2020] [Indexed: 12/20/2022] Open
Abstract
Previous studies have found gender differences in body-related attentional bias (AB), with women showing AB towards weight-related body parts. However, few studies have assessed the relationship between body-related AB and muscularity dissatisfaction (MD) in men. This study aimed to assess the presence of muscle-related AB in men, using a combination of a virtual reality (VR) embodiment-based technique and eye-tracking (ET) technology. Twenty men with high MD and 20 with low MD, owned a virtual avatar that had the same silhouette and body mass index as the participant. To analyze the gaze data, muscle-related areas of interest (M-AOIs) and nonmuscle-related areas of interest (NM-AOIs) were defined. The complete fixation time and the number of fixations on each AOI were recorded. Mixed between (group)-within (AOI_condition) analyses of variance showed a statistically significant interaction between group and time (p < 0.05) in both AB measures. Follow-up analyses revealed an AB towards M-AOIs only in men with high MD. Overall, men with high MD spent more time looking and displayed a higher number of fixations on M-AOIs, specifically the chest and shoulders, compared to men with low MD. This study provides new information about the relationship between MD and body-related AB in men. Combining VR with ET technologies presents interesting opportunities in the study of body image in men.

Abstract
This study aimed to examine self-body recognition in women with high (HWSC) and low weight and shape concerns (LWSC). Thus, the detection rate, the reaction time and the perceptual threshold for recognizing one's own body in a morphed body were measured in n = 25 women with HWSC and n = 26 women with LWSC. Furthermore, by using steady-state visual evoked potentials (SSVEPs), neuronal correlates of body recognition were recorded. The perceptual threshold for recognizing one's own body was higher for women with HWSC in the case of a morph with a thinner body. No group differences emerged for morphs with obese or average-weight bodies. The SSVEP amplitudes did not differentiate between one's own and another body in either group. The results suggest that for women with HWSC, their negative body schemata might hamper recognition of their own body in a thinner morph. Otherwise, self-body recognition is similar in women with LWSC and HWSC.

Abstract
This systematic review and meta-analysis aimed to quantify the effects of laboratory-based interventions targeting specific mechanisms of food craving, to identify moderators of effects, and to qualitatively summarize findings. The study was conducted and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Sixty-nine studies were included in the quantitative synthesis, and separate meta-analyses were conducted for the outcomes self-reported craving and objective food intake. Results show small to medium positive effects across specific craving interventions on both outcomes. Effect sizes were partly moderated by intervention type. The most effective intervention regarding food intake was in sensu cue exposure. For subjective craving, the most robust evidence was found for beneficial effects of cognitive regulation strategies (ie, reappraisal, suppression, and distraction). Results further indicate that training inhibitory control through behavioral inhibition might be more effective than approach-avoidance training when considering its effect on subjective craving and food intake. People with external eating habits, overeating, or loss-of-control eating might benefit from these types of specific craving interventions. Future research should focus on long-term effects, transferability, and effectiveness in clinical samples.

Abstract
BACKGROUND Findings are mixed regarding the association of electroencephalographic (EEG) attentional bias measures and body weight, with few studies measuring food craving or intake and no study reporting oscillatory measures. METHODS EEG data were collected while 28 satiated adolescents (14 overweight/obese) viewed pictures of neutral, low-calorie food, and high-calorie food stimuli and rated their desire to eat, before having access to high-calorie snacks. RESULTS Unlike normal-weight adolescents, overweight/obese participants showed similar P300 amplitudes for high- and low-calorie food, and strongest event-related alpha band desynchronization for low-calorie stimuli. P300 amplitudes and state craving for low-calorie food furthermore predicted snack intake in this group. CONCLUSIONS The current research focus in overweight/obesity might need to be extended to include low-calorie food. While all participants showed an attentional bias for high-calorie food, it was the processing of low-calorie food which distinguished the two weight groups on measures of neural activity and which was associated with snack food intake in the overweight/obese group.

Abstract
PURPOSE Cognitive-behavioral theories posit that body checking decreases negative emotions, but increases levels of arousal. However, few studies have investigated the effects of body checking on the course of emotional states. Therefore, the current study examined how normal-weight females with higher and lower eating, weight, and shape concerns feel during a checking episode of their most-liked and least-liked body parts. METHODS In an online design, levels of negative emotions and arousal were retrospectively assessed before, during, immediately after, and 15 min after an individually remembered body-checking episode. Participants (N = 355) also rated their subjective satisfaction with specific body parts. RESULTS Levels of negative emotions were lower 15 min after the checking episode of most-liked and least-liked body parts than before the episode. However, negative emotions increased during the checking episode of least-liked body parts, but subsided thereafter. The levels of arousal increased during the checking episodes of most-liked and least-liked body parts and decreased afterwards, and females with higher concerns reported greater levels of arousal than females with lower concerns. Furthermore, females with higher concerns reported more body checking than those with lower concerns. CONCLUSIONS The results support the assumptions of the cognitive-behavioral theories, as body checking led to a decrease in negative emotions in the longer term, and levels of arousal increased during the checking episode. The greater levels of arousal in females with higher concerns, and their pronounced body-checking behavior, might enhance their existing concerns and increase the risk of disordered eating. LEVEL OF EVIDENCE Level V, descriptive study.

Abstract
Body image disturbance, consisting of an affective (body dissatisfaction) and perceptual (body distortion) component, is not only found in eating disorders, but is also present in healthy individuals, affecting their psychological well-being and everyday life. A higher body mass index is associated with higher body dissatisfaction, whereas results in relation to body distortion are mixed. Furthermore, body dissatisfaction is associated with a weight-related attentional bias. This study aimed to investigate the mediating role of a weight-related attentional bias in the relationship between body mass index and body image disturbance. Forty-one college women took part in a virtual reality and eye tracking procedure, in which the illusion of owning a virtual avatar with their body measurements was induced. During this procedure, body-related attentional bias was measured and afterwards body image disturbance was assessed. Mediation analysis revealed that weight-related attentional bias mediated the relationship between body mass index and body dissatisfaction (but not distortion). These findings suggest that modifying weight-related attentional bias would be a useful treatment target for improving body dissatisfaction. In addition, virtual reality technology could serve as an innovative method for modifying attentional bias in an ecologically valid way. HIGHLIGHTS: This Virtual Reality and Eye-Tracking study expands our knowledge about the relation between body mass index, body-related attention and body image disturbances. The results suggest that attentional bias towards weight-related body parts mediates the relation between BMI and body dissatisfaction. On the contrary, the relation between BMI and body distortion was not significant.

Abstract
Accumulating lab-based studies have identified attentional biases in processing of negative appearance-related information among individuals with elevated trait body shape and weight dissatisfaction (BD). How these biases translate into experiences of BD in daily life remains unclear and, hence, was the focus of the present study. Thirty-eight women aged between 18-40 years completed a baseline survey and modified dot-probe task with both fat and thin appearance-related stimuli in a laboratory setting. Participants also downloaded a smartphone app that prompted them 10 times per day for 7 days to rate current body dissatisfaction. Results revealed that heightened BD in daily life tended to be transitory, and followed by a substantially lower rating of BD by the next survey (∼1-2 h later). For individuals with elevated trait BD and facilitated attention towards thin body images, this reduction in state BD was more gradual. Surprisingly, delayed disengagement towards thin body images was associated with greater reduction in state BD. Consistent with the hypothesis, moderating effects were not observed when initial state BD level was low. Susceptibility for immediate, short-term attentional biases towards appearance-related information may be a vulnerability factor for the prolonged persistence of negative body image experiences in daily life.

Abstract
OBJECTIVE Given the growing interest in personality traits among the young population with eating disorders (EDs) and the recognition that a better understanding of personality can facilitate clinical management, this meta-analytic study reviewed evidence concerning the relationship between personality traits and the presence of an ED during adolescence. METHOD We conducted a systematic literature search to identify studies that examined personality traits among adolescents with an ED (anorexia nervosa, bulimia nervosa, binge-eating disorder, eating disorder not otherwise specified) and that compared these traits with a normative group without an ED. The personality traits investigated in the selected studies were organized according to the personality trait domains presented in the Diagnostic and Statistical Manual of Mental Disorders (fifth ed.). Effect sizes of the mean differences were calculated for each domain. We performed meta-regressions to assess the moderating effect of ED subtype and age on the combined effect sizes. RESULTS Twenty-six studies met our inclusion criteria, containing a total of 63 effect sizes. Adolescents with EDs differed from the non-ED group according to traits related to negative affectivity (g = 0.78), detachment (g = 0.69), and conscientiousness (g = -0.53). The presence of an anorexia nervosa diagnosis moderated the relationship between an ED and personality traits; this diagnosis was more strongly associated with conscientious traits compared to other EDs. DISCUSSION Our findings provide evidence that personality traits are related to EDs in adolescents. Thus, considering personality traits could lead to a better understanding of etiological and maintenance factors for EDs.

Abstract
A disturbed body image with fluctuating behavioral patterns of body related avoidance (BA) and body checking (BC) characterizes individuals with eating disorders (EDs) such as anorexia (AN) or bulimia nervosa (BN). So far, these behavioral body image components are mostly assessed via self-report instruments thereby neglecting their behavioral and partially automatic characteristics. Therefore, behavioral measures of BA and BC are needed. The present study investigates a behavioral assessment task for BA and BC in a sample of patients with diagnosed EDs and healthy controls. The sample consisted of 40 women diagnosed with either BN (N = 19) or AN (N = 21; ED sample) and 24 non-eating disordered, healthy female controls (HC). Within the Body Image Approach Task (BIAT) participants viewed photos of their own body (self-image) and a matched control body (other-image) by zooming the photos closer toward them (image became more focused) on the screen. The BIAT yields zoom-levels recorded separately for self- relative to other-images. Further measures were attractiveness ratings of these body images as well as questionnaire measures of BA, BC, and general ED symptomatology. Results showed that despite strong body dissatisfaction and clearly negative ratings of self- relative to other-images in both EDs, no group differences were found in approach to self-images on zoom-level as measured with the BIAT. Correlational analysis in each group indicated that zoom-level was positively related to BA scores in the HC group only. Yet, stepwise regression analyses revealed that attractiveness ratings explained most of the variance accounted by BA in predicting zoom-level. In sum, the BIAT seems suitable to assess BA and self-rated body attractiveness, but only in healthy individuals with subclinical levels on these constructs. It does not seem to capture the body image satisfaction or the behavioral components of body image disturbances in AN or BN or it conflates the opposed influences of BA and BC. Further experimentation is needed to adapt measures of behavioral body image components to the processes evoked in patients with ED during confrontation with body images.

Abstract
One factor, believed to predict body dissatisfaction is an individual’s propensity to attend to certain classes of human body image stimuli relative to other classes. These attentional biases have been evaluated using a range of paradigms, including dot-probe, eye-tracking and free view visual search, which have yielded a range of – often contradictory – findings. This study is the first to employ a classic compound visual search task to investigate the relationship between body dissatisfaction and attentional biases to images of underweight and with-overweight female bodies. Seventy-one undergraduate females, varying their degree of body dissatisfaction and Body Mass Index (BMI), searched for a horizontal or vertical target line among tilted lines. A separate female body image was presented within close proximity to each line. On average, faster search times were obtained when the target line was paired with a uniquely underweight or with-overweight body relative to neutral (average weight only) trials indicating that body weight-related images can effectively guide search. This congruent search effect was stronger for individuals with high eating restraint (a behavioral manifestation of body image disturbance) when search involved a uniquely underweight body. By contrast, individuals with high BMIs searched for lines more rapidly when paired with with-overweight rather than underweight bodies, than did individuals with lower BMIs. For incongruent trials – in which a unique body was paired with a distractor rather than the target – search times were indistinguishable from neutral trials, indicating that the deviant bodies neither compulsorily “captured” attention nor reduced participants’ ability to disengage their attention from either underweight or with-overweight bodies. These results imply the existence of attentional strategies which reflect one’s current body and goal-directed eating behaviors.

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.
