Srivastava P, Giannone A, Lampe EW, Clancy OM, Fitzpatrick B, Juarascio AS, Manasse SM. A naturalistic examination of feeling fat: Characteristics, predictors, and the relationship with eating disorder behaviors. Int J Eat Disord 2024. [PMID: 38829201 DOI: 10.1002/eat.24232] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2023] [Revised: 05/10/2024] [Accepted: 05/13/2024] [Indexed: 06/05/2024]
Abstract
OBJECTIVE Although literature implicates feeling fat in the maintenance of binge-spectrum eating disorders (EDs; e.g., bulimia nervosa, binge-ED), research in this area is small, nascent, and relies on retrospective self-report. The current study sought to understand the temporal pattern of feeling fat and its role as a precipitant and consequence of ED behaviors. METHODS Totally 106 treatment-seeking adults with binge-spectrum EDs completed 7-14-day ecological momentary assessments. They rated feeling fat, negative affect states, and reported on ED behaviors six times per day. Multilevel models evaluated whether feeling fat mediates prospective links between negative affect states and ED behaviors, assessed if negative affect states mediate the prospective association of feeling fat on ED behaviors, and examined the bidirectional prospective association between feeling fat and ED behaviors. RESULTS Feeling fat was highest in the early morning (6-8:59 a.m.). Individuals with binge-ED-spectrum EDs demonstrated greater variability in feeling fat than those with bulimia nervosa-spectrum EDs who had stable and high levels of feeling fat. Guilt, sadness, anxiety, and the overall NA at Time 2 mediated the prospective associations between at Time 1 feeling fat and Time 3 dietary restraint, actual dietary restriction, and compensatory exercise. There was a bidirectional prospective association between feeling fat and binge eating. DISCUSSION Feeling fat serves as a proximal predictor and mediator of the prospective association between guilt and binge eating. Feeling fat and binge eating mutually reinforce each other. PUBLIC SIGNIFICANCE Little is understood regarding the experience of feeling fat in natural environments among individuals with binge-spectrum eating disorders. We found that the risk for having the experience of feeling fat is high in the morning and evening. Feeling fat triggers guilt, anxiety, and sadness which in turn, increases engagement in dietary restraint/restriction and compensatory exercise. Feeling fat also triggers binge eating, and binge eating leads to feelings of fatness.

Abstract
Body dissatisfaction (BD) includes negative thoughts and feelings about one's body shape. Although typically assessed as a trait, BD has been found to fluctuate within a day. The present study examined whether daily instability in BD differs according to trait BD, eating disorder (ED) diagnosis, and engagement in maladaptive exercise. Participants with EDs (n = 166) and controls (n = 44) completed a self-report measure of trait BD and reported BD and engagement in maladaptive exercise five times daily for 14 days as part of an ecological momentary assessment protocol. BD instability was calculated as adjusted mean squared successive difference. On average across assessments, participants with EDs reported a 16% change in their BD ratings between consecutive assessments, which was significantly higher than the 12% change in controls. Trait BD was significantly inversely associated with BD instability in individuals with EDs, but not in controls. BD instability did not differ across ED diagnoses or between days with versus without maladaptive exercise. Findings suggest that BD is a dynamic state that varies within a day, especially in participants with EDs. Further research is needed to clarify whether this heightened instability in BD is a clinically relevant factor underlying ED symptoms.

Abstract
Background Food waste remains a major problem for the world and food security. Despite the fact that consumers are significant producers of food waste, little research attention has been paid to college students. The present study aimed to assess food waste and the influence factors among college students. Additionally, the goal was to improve college students' food waste attitudes and behaviors through labor education. Methods Through an online questionnaire survey, 407 college students from three universities were asked about food waste; 27 students of them were randomly selected as the research object, and labor practice was carried out in groups in the student cafeteria. Mann-Whitney U test was performed to show food waste behavior of college students and logistical regression analysis was used to analyze the factors affecting food waste behavior. Results The results indicated that the food waste is more serious among college students in East China, senior or female students, BMI plays a positive role in food waste among college students, while monthly consumption and peers waste play a negative role in food waste. After participating in the labor education, the students' views and practices toward their peer's food waste have improved. Conclusion The implementation of labor education in college canteens is conducive to the establishment of a correct outlook on labor as well as saving consciousness among college students, and to the formation of a social consciousness of saving.

Abstract
OBJECTIVE Eating expectancies (EE) are the anticipation of various benefits or detriments from eating, with mood regulation being a salient type of EE associated with eating disorders. This study examined the convergent and predictive validity of ecological momentary assessment (EMA) mood regulation EE items, including mood improvement and mood worsening EE. METHODS Thirty women with binge-eating pathology completed a 14-day EMA protocol, which included measures of mood regulation EE, affect, appetite, appearance- and body-related factors and disordered-eating behaviours. RESULTS Greater within-subjects hunger and lower within-subjects positive affect and fullness were related to elevated mood improvement EE. Higher within-subjects appearance concerns, fullness, body social comparisons and thinness pressure were associated with higher mood worsening EE. Greater within-subjects mood worsening EE predicted greater likelihood of vomiting at the subsequent time point, but there were no within-subjects associations between mood improvement EE and behaviours. Yet, greater between-subjects mood worsening EE were associated with more restraint/restriction and binge eating, and greater between-subjects mood improvement EE were associated with more binge eating. CONCLUSIONS Findings support the convergent validity of EMA mood regulation EE items. There was limited predictive validity evidence, suggesting complexities in how mood regulation EE predict behaviour in daily life.

Abstract
OBJECTIVE Momentary worsening (i.e., greater than one's average levels) of state body dissatisfaction (BD) has been implicated as a proximal risk factor for eating disorder (ED) behaviors in binge-spectrum EDs. Yet, research exploring the prospective association between noneating activities in daily life (e.g., chores, self-care/coping) and momentary state BD remains limited. Understanding the momentary link between engagement in noneating activities and state BD, and pathways through which engagement in said activities influences momentary state BD is critical to informing treatments. The current ecological momentary assessment (EMA) study examined whether (1) engagement in noneating activities at Time 1 prospectively predicted momentary state BD at Time 2 and (2) reward drawn from noneating activities at Time 1 mediates the prospective association between engagement in noneating activities at Time 1 and momentary state BD at Time 2. METHOD Sixty-six adults with transdiagnostic binge eating completed an EMA protocol over 7-14 days. Participants received six EMA signals per day (total EMA observations = 4038). Multilevel modeling was used to examine the research questions. RESULTS Engagement in an indoor hobby, outdoor recreation, socializing, and self-care/coping strategies prospectively predicted momentary state BD improvements, while using TV/social media and cooking prospectively predicted momentary state BD worsening. Reward drawn from engagement in these noneating activities mediated the associations. DISCUSSION If replicated, these findings suggest that increasing the frequency of certain noneating activities and enhancing their rewarding aspects to improve state BD and decrease ED behavior risk during treatment may be worthy of further exploration. PUBLIC SIGNIFICANCE Momentary worsening of state body dissatisfaction (BD) is a risk factor for eating disorder behaviors in individuals with binge eating. This study found that engaging in certain noneating activities (e.g., socializing) prospectively predicted momentary improvements in state BD, while other noneating activities (e.g., cooking) predicted momentary worsening of state BD. Reward drawn from activities mediated these relations. To improve state BD, treatments should target the frequency of, and reward obtained from these noneating activities.

Abstract
Background Previous studies have focused on the comorbidity of appearance anxiety and social anxiety, but few studies have focused on the protective role of self-compassion as underlying this mechanism, in young people like University students. With the increase of prevalence of appearance anxiety and social anxiety in this age group, it is necessary to explore factors that can buffer against the symptoms of these disorders. Therefore, the aims of this study were to research the effect of appearance anxiety and social anxiety, then to examine whether self-compassion has a protective effect on social anxiety. Method The study was cross-sectional and conducted online from October 2021 to November 2021 in Jilin Province, China. A total of 63 Universities in the province participated in this study, totaling 96,218 participants, of which 40,065 were males (41.64%) and 56,153 females (58.36%), the mean age of the sample was 19.59 (±1.74). The Appearance Anxiety Scale-Brief Version was used to measure appearance anxiety. The Social Anxiety subscale of the Self-Consciousness Scale was used to measure social anxiety. The Self-Compassion Scale-Short Form was used to measure self-compassion. A structural equation model (SEM) was run to examine the mediating effect of self-compassion on the relationship between appearance anxiety and social anxiety. Result Overall, appearance anxiety was positively associated with social anxiety [β = 0.334, 95% CI = (0.328, 0.341), p < 0.001], and self-compassion could mediate the effect of appearance anxiety on social anxiety [β = 0.128, 95% CI = (0.124, 0.132), p < 0.001]. Self-compassion played a partial mediating role between appearance anxiety and social anxiety. Conclusion Individuals with high appearance anxiety are also at higher risk of social anxiety, but self-compassion can buffer against this relationship. These findings begin to explore novel approaches to treat social anxiety and can provide valuable insights for self-compassion training.

Abstract
INTRODUCTION Previous studies have suggested the positive influence of social support on the treatment and recovery of eating disorders (EDs). Yet, more research is needed on how objective and subjective social support differ between ED diagnostic groups using nationally representative data. Therefore, the current secondary data analysis examined associations between EDs and objective and subjective social support using data from the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III) study. METHODS Participants completed measures of lifetime and past year diagnostic criteria for anorexia nervosa (AN), bulimia nervosa (BN), and binge-eating disorder (BED) and items assessing objective social support (i.e., number of close friends and close relatives) and subjective social support (i.e., perceptions of availability of support). RESULTS Compared to those without EDs, those with AN, BN, and BED had poorer subjective social support-or lower perceptions of social support. However, there were fewer differences regarding objective social support. Individuals with BN reported a lower number of close relatives compared to those without EDs and those with AN, but there were no differences in the number of close friends between ED groups. Those who experienced remission from EDs had higher perceptions of social support compared to those with past year EDs. DISCUSSION The findings show deficits in subjective social support across EDs but only lower objective social support in BN. This highlights the clinical utility of increasing perceptions of social support across EDs. The findings also show the importance of perceived social support in recovery from EDs.

Abstract
PURPOSE Anorexia nervosa (AN) is a life-threatening condition in which temperament, anxiety, depression, and core AN body-related psychopathology (drive for thinness, DT, and body dissatisfaction, BD) are intertwined. This relationship has not been to date disentangled; therefore, we performed a multiple mediation analysis aiming to quantify the effect of each component. METHODS An innovative multiple mediation statistical method has been applied to data from 184 inpatients with AN completing: Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire, Eating Disorders Inventory-2, State-Trait Anxiety Inventory, and Beck Depression Inventory. RESULTS All affective temperaments but the hyperthymic one were involved in the relationship with DT and BD. Only the anxious temperament had a significant unmediated direct effect on DT after the strictest correction for multiple comparisons, while the depressive temperament had a significant direct effect on DT at a less strict significance level. State anxiety was the strongest mediator of the link between affective temperament and core AN body-related psychopathology. Depression showed intermediate results while trait anxiety was not a significant mediator at all. CONCLUSION Affective temperaments had a relevant impact on body-related core components of AN; however, a clear direct effect could be identified only for the anxious and depressive temperaments. Also, state anxiety was the strongest mediator thus entailing interesting implications in clinical practice. LEVEL OF EVIDENCE V, cross-sectional study.

Abstract
PURPOSE This study aims to determine the factors that influence food addiction (FA) in female nursing students. DESIGN AND METHODS Twenty-four out of 51 (mean age = 19.8 ± 1.36) women were identified from a sample of 645, who met the diagnostic criteria of FA using the Yale Food Addiction Scale (YFAS), and participated in this qualitative study. FINDINGS Results of the study revealed that the factors affecting FA in students were conceptualized under four themes: "Social circle," "Situational and emotional signs," "Cognitive process," and "Weight gain and quality of life." PRACTICE IMPLICATIONS It is recommended to offer specific intervention programs including personal or group counseling for those, recognized as having FA based on an addiction model, and to have a successful therapy.

Abstract
The current study used ecological momentary assessment (EMA) to investigate whether appearance-based comments, social and performance-based evaluations affected levels of body dissatisfaction (BD) and urges to engage in disordered eating behaviors (DE) throughout daily life. A total of 620 participants completed a baseline questionnaire assessing sociodemographic variables. Participants then downloaded a mobile app which alerted them to complete short surveys assessing their levels of BD, DE urges, and experiences of receiving comments and evaluations six times per day for 7 days. Negative appearance-based comments predicted greater levels of state BD, while positive appearance comments predicted lower levels of state BD. Negative social and performance-based evaluations predicted an increase in state BD, while positive evaluations predicted a decrease in this outcome variable. No significant predictor was found for the DE urge outcomes. The present findings suggest that receiving negative and positive feedback in various domains of one's life may predict opposite outcomes for body image. However, these effects do not necessarily associate with urges to engage in DE in a nonclinical population.

Abstract
PURPOSE Maladaptive exercise is common among individuals with binge-spectrum eating disorders. One mechanism that may drive engagement in exercise in this population is state body dissatisfaction. However, no studies to date have examined prospective, momentary relationships between state body dissatisfaction and exercise. METHODS Adults with binge-spectrum eating disorders (N = 58) completed a 7-14-day ecological momentary assessment protocol assessing exercise and state body dissatisfaction several times per day. Multilevel models were used to evaluate prospective reciprocal associations between state body dissatisfaction and exercise. Mixed models examined trajectories of change in state body dissatisfaction pre- and post-exercise. Additional models examined exercise type (maladaptive vs. adaptive) as a moderator. RESULTS Momentary increases (i.e., greater than one's average levels) in state body dissatisfaction at any given timepoint did not prospectively predict engagement in exercise at the next nearest timepoint. Exercise at any given timepoint did not prospectively predict momentary increases in state body dissatisfaction. State body dissatisfaction was found to increase in the initial hours preceding an exercise episode (linear estimate, β = - 0.012, p = 0.004). State body dissatisfaction did not significantly change in the hours following engagement in exercise. Exercise type did not moderate these associations. CONCLUSION If replicated, our results may suggest that momentary increases in state body dissatisfaction may not be associated with exercise behaviors in individuals with binge-spectrum eating disorders. LEVEL OF EVIDENCE Level V: Opinions of authorities, based on descriptive studies, narrative reviews, clinical experience, orreports of expert committees.

Abstract
PURPOSE Body dissatisfaction (BD) is supported as a maintenance factor for eating disorders (EDs) characterized by binge eating (BE). Although it is traditionally conceptualized as a trait construct, ecological momentary assessment (EMA) studies have shown that it fluctuates within-day and that momentary elevations in BD prospectively predict near-time ED behaviors. However, less is known about the contextual factors that precipitate these fluctuations in BD. METHODS The current study thus sought to examine whether certain internal (i.e., negative affect, shape/weight-related cognitions) and environmental (i.e., attending social events, being exposed to thin-ideal media, spending time on social media) factors prospectively predict momentary elevations in BD in females with BE. Participants (n = 25) completed an EMA protocol over 14 days. RESULTS Data on BD and internal and environmental factors were analyzed using generalized estimating equations. Results showed that (1) greater than one's usual negative affect and shape/weight-related cognitions, and (2) spending time on social media prospectively predicted momentary elevations in BD. Interestingly, attending social events prospectively predicted momentary reductions in BD. CONCLUSION These findings may have important implications for conceptualizing and managing BD to prevent ED behaviors. LEVEL OF EVIDENCE Level II, controlled trial without randomization.

Abstract
The attention regarding individuals’ external appearance and social identity provides a unique perspective to reveal the cause of their behavior. This study explored the formation mechanism of individual food waste behavior in China from the perspective of appearance image construction and social image construction, especially considering the role of emotion, education level, and body mass index (BMI) in relationship transmission. This study collected data by questionnaire in 133 cities in 32 provinces of China. By using the methods of factor analysis, correlation analysis, and hierarchical regression analysis, the results show that individuals with high need for external appearance image (r = 0.242, p < 0.001) and social image construction (r = 0.31, p < 0.001) are more likely to waste food. In terms of transmission mechanisms, positive emotions (e.g., excitement) (β = 0.104~0.187, 95% confidence interval) and negative emotions (e.g., anxiety and disgust) (β = 0.08~0.177, 95% confidence interval) are the intermediary factors of image construction affecting food waste behavior, and emotional fluctuations can aggravate individuals’ food waste behavior. In terms of interaction effects, BMI significantly positively regulates the predictive effect of image construction on food waste behavior, while the level of education buffers this predictive effect. Finally, relevant policy suggestions are put forward to guide individuals to reduce food waste.

Dynamic associations between anxiety, stress, physical activity, and eating regulation over the course of a behavioral weight loss intervention. Appetite 2022; 168:105706.

Abstract
Negative emotional experiences are associated with dysregulated eating behaviors that impede weight management. While weight loss interventions promote physical activity and self-regulation of eating, no studies have examined how physical activity may directly influence eating by attenuating associations between negative emotions and eating. OBJECTIVE The current study examined how momentary negative emotions (stress and anxiety), moderate-to-vigorous intensity physical activity (MVPA), and their interactions predict eating dysregulation (i.e., intensity of eating temptations, inability to resist eating tempting foods, overeating), as well as how these associations change during a weight loss intervention. METHODS Women with overweight/obesity (N = 55) completed 14-day ecological momentary assessment (EMA) protocols with objective measurement of physical activity (i.e., bout-related MVPA time) before and after a three-month internet-based weight loss program. RESULTS Three-way interactions emerged predicting overeating and eating tempting foods. When women experienced higher than usual levels of momentary anxiety or stress at end-of-treatment, they were less likely to subsequently overeat or eat tempting foods when they had recently engaged in more MVPA (relative to their usual level). No significant associations were found for ratings of temptation intensity. CONCLUSIONS Findings suggest MVPA may exert direct effects on eating regulation. Specifically, MVPA appears to increasingly buffer the effect of negative emotional states on dysregulated eating behavior over the course of a weight loss intervention. Future work is needed to develop ways of communicating to patients how activity can have both indirect and direct effects on body weight, and examine whether such knowledge improves outcomes.

Abstract
Obsessive-compulsive disorder (OCD) and eating disorders (ED) share common causal factors and often represent similar entities. Studies on obsessive-compulsive disorders and eating disorders reveal a significant correlation between maladaptive perfectionism. The objective of this study is to evaluate the predictive variables of perfectionism in patients diagnosed with Anorexia Nervosa (AN), Bulimia Nervosa (BN) and OCD using a structural equation model (SEM). The sample consisted of 187 participants (60.9% women, 39.1% men) with a mean age of 26.68 (SD = 10.97). The findings reveal that the model is the same in all the disorders evaluated, achieving an adequate fit: χ2 = 7.95 (p = 0.000), RMSEA = 0.087 (95% confidence interval: 0.00 to 0.02), CFI = 0.991, TLI = 0.951 and with an overall predictive capacity of around 30% (CD = 0.318). It is recommended that future studies address the subtypes of disorders evaluated using longitudinal designs.

Abstract
Body dissatisfaction (BD) and preoccupation with thoughts of food (PTF) are intertwined and are components of thought-shape fusion. Thought-shape fusion describes the process by which PTF lead to beliefs about weight and shape. To study thought-shape fusion in daily life and explore various transitions between BD and PTF, 30 women with binge eating completed ecological momentary assessment for 14 days. BD and PTF were assessed using continuous rating scales at each prompt. Multi-state modeling, which analyzes micro-temporal transitions between discrete states, was used to examine transitions among four states created with BD and PTF ratings. The four states included low BD/low PTF, low BD/high PTF, high BD/low PTF, and high BD/high PTF. Affect and disordered eating were examined as covariates of state transitions. Results showed high BD states were self-perpetrating, such that when in high BD states, transition to low BD states were less likely. Regarding covariates, positive affect buffered against maladaptive transitions whereas negative affect and disordered eating increased risk. Findings highlighted high BD states as influential, and negative affect and disordered eating as risk factors and positive affect as preventive. This study enhances theory of thought-shape fusion and implicates transitions from BD to PTF as possible underlying transitions.

Stress appraisal prospectively predicts binge eating through increases in negative affect. Eat Weight Disord 2021; 26:2413-2420.

Abstract
PURPOSE Ecological momentary assessment (EMA) studies preliminarily support the transactional model of emotion regulation in eating disorders, such that heightened stress appraisal (i.e., the cognitive evaluation of an event's demands) results in increased negative affect (NA) and subsequent binge eating (BE). However, the temporal relationships between these variables and the magnitude of stress appraisal that is clinically significant require clarification. The current study aimed to extend previous research by (1) examining the temporal relationship between stress appraisal, changes in NA, and BE using three timepoints, (2) exploring what magnitude of momentary stress appraisal results in clinically significant increases in NA and BE, and (3) characterizing what stressors are associated with clinically significant stress appraisal. METHODS 37 adult females completed an EMA protocol assessing momentary stressors, stress appraisal, NA, and BE over 2 week duration. Multilevel mediation models were used to test the study aims. RESULTS Momentary increases in stress appraisal significantly predicted binge eating through increases in NA. Stress appraisal ratings of 0.50 SD higher relative to one's average stress appraisal began to significantly predict the likelihood of BE through increases in NA, and the likelihood of BE occurrence increased with every 0.25 increments in momentary stress appraisal. Work/school stressors and interpersonal stressors were the most commonly endorsed stressors of clinically significant stress appraisal. CONCLUSION The current study supported the transactional model of emotion dysregulation in a binge eating sample and supports the use of momentary interventions at times of clinically significant stress appraisal to reduce BE risk. LEVEL OF EVIDENCE Level II, controlled trial without randomization.

Abstract
BACKGROUND Stress is a dynamic construct that predicts a range of health behaviors and conditions, including binge eating and excess weight. Thus far, there have been limited and inconsistent findings regarding stress responses in binge-eating disorder (BED) and insufficient consideration of temporal patterns of stress responses across the weight spectrum. PURPOSE The present study used ecological momentary assessment (EMA) to examine stress reactivity (i.e., the magnitude of the initial stress response), recovery (i.e., how long the stress response lasts before returning to baseline), and pileup (i.e., accumulation of repeated experiences of stressors and responses over time) as predictors of binge-eating symptoms (BES) and food craving in BED. METHODS Adults with BED (N = 115) completed a 7 day EMA protocol assessing stressful events, perceived stress, binge eating, and food craving prior to being randomized to a behavioral intervention. RESULTS Generalized estimating equations indicated that moments of greater stress pileup predicted greater subsequent BES (within-person effect). Participants with higher perceived stress and pileup reported greater overall BES and craving, and those with better recovery reported higher overall craving (between-person effects). CONCLUSIONS Findings highlight the importance of considering the dynamic nature of stress responses and, particularly, that the accumulation of stress over the day is an important trigger for BES.

Abstract
This study examined the relative influence of trait and state weight, shape, and eating concerns on dysregulated eating in the daily lives of sexual minority women with overweight and obesity. This study is a secondary analysis of data from an Ecological Momentary Assessment (EMA) study of 55 sexual minority women with overweight/obesity. Trait shape, weight, and eating concerns were assessed at baseline. For the following five days, participants used a smartphone to report state weight/shape concerns, overeating, and binge eating five times daily. Women who endorsed higher levels of trait weight, shape, and eating concerns at baseline reported more frequent state weight/shape concerns in daily life. Trait eating concerns were associated with higher odds of binge eating during EMA, but trait weight/shape concerns were unrelated to future dysregulated eating. In daily life, state weight/shape concerns was associated with greater risk for over/binge eating at the concurrent EMA prompt, the subsequent EMA prompt, and over the course of a full day, independent of trait concerns. State weight and shape concerns may play an important role in predicting dysregulated eating in daily life among sexual minority women of higher body weight.

Abstract
The integrative cognitive-affective therapy (ICAT) momentary maintenance model proposes a number of situational factors that precipitate eating disorder (ED) behaviors and cognitions. The current study examines momentary situational triggers in relation to a broad range of ED symptoms in a diagnostically heterogeneous sample of individuals with ED psychopathology. In the current study, 30 women with binge eating pathology completed a 14-day ecological momentary assessment (EMA) protocol during which they responded to five random signals throughout the day. During signaled assessments, participants completed measures of self-criticism, interpersonal problems, self-regulation of binge eating, appearance concerns, and cognitive and behavioral ED symptoms. Multilevel models were used to examine prospective associations between hypothesized ICAT maintenance factors and ED symptoms. Within-subjects self-criticism prospectively predicted vomiting, restriction, preoccupation with thoughts of food, and urges to eat. Within-subjects interpersonal problems prospectively predicted vomiting, and within-subjects appearance concerns prospectively predicted preoccupation with thoughts of food. There were no significant predictors of binge eating. These results provide some support for hypothesized momentary situational triggers of ED symptoms in the momentary maintenance model of ICAT using naturalistic, momentary assessment. Specifically, it may be particularly useful for interventions such as ICAT to address momentary self-criticism when targeting a range of ED symptoms.

Abstract
Loss of control eating is a core, transdiagnostic eating disorder symptom associated with psychological distress, functional impairment, and reduced quality of life. However, the factors that contribute to persistent loss of control eating despite negative consequences are not fully understood. Understanding the mechanisms that maintain loss of control eating is crucial to advance treatments that interrupt these processes. Affect regulation models of loss of control eating hypothesize that negative emotions trigger loss of control eating, and that loss of control eating is negatively reinforced because it temporarily decreases negative affect. Several variations on this basic affect regulation model have been proposed, including theories suggesting that negative affect decreases during loss of control eating rather than afterwards (escape theory), and that loss of control eating replaces one negative emotion with another that is less aversive (trade-off theory). Experience sampling designs that measure negative affect and eating behavior multiple times per day are optimally suited to examining the nuanced predictions of these affect regulation models in people's everyday lives. This paper critically reviews experience sampling studies examining associations between negative affect and loss of control eating, and discusses the implications for different affect regulation models of loss of control eating. The review concludes by proposing an expanded affect-focused model of loss of control eating that incorporates trait-level individual differences and momentary biological and environmental variables to guide future research. Clinical implications and recommendations are discussed.

Abstract
Aim To investigate the psychological status of medical staff with medical device-related nasal and facial pressure ulcers (MDR PUs) during the outbreak of COVID-19, analyse the correlation between their psychological status and personality traits, so as to provide a reference for personalized psychological support. Design A total of 207 medical staff who were treating the COVID-19 epidemic from Hunan and Hubei provinces were enrolled in this analytic questionnaire-based study. Methods We used these measures: Eysenck Personality Questionnaire Short Scale (EPQ-RSC), Social Appearance Anxiety Scale (SAAS), Positive and Negative Affect Scale (PANAS) and demographic information forms online. Results Medical staff wearing protective equipment are particularly susceptible to nasal and facial MDR PUs, which is increasing their social appearance anxiety; neuroticism is significantly related to social appearance anxiety and negative emotion. We should pay more attention to their psychological state, cultivate good personality characteristics and reduce negative emotions, and thereby alleviate their MDR PUs-related appearance anxiety.

Abstract
PURPOSE OF REVIEW Ecological momentary assessment (EMA) is an important tool for clarifying common precipitants and consequences of eating disorder symptoms that might be meaningfully targeted in treatments for these pernicious disorders. This article reviews recent advances in EMA work conducted within clinical eating disorder samples. RECENT FINDINGS Published studies from the past 2.5 years can broadly be categorized as involving functional analysis of eating disorder behaviors, examining hypothesized predictors of eating disorder symptoms, or applying novel approaches to EMA data. Examples of the latter category include the use of latent profile analysis with EMA data, integration of neurocognitive (e.g., ambulatory inhibitory control task) or biological indicators (e.g., fMRI, plasma leptin), and examining changes in associations between momentary variables over time through multiwave EMA data collection. SUMMARY EMA studies in eating disorders have advanced significantly in recent years, with findings demonstrating strong support for the emotion regulation function of eating disorder behaviors and momentary predictors of distinct eating disorder symptoms. The use of novel statistical and data collection approaches represent exciting areas of growth, with likely implications for intervention approaches, including those that utilize ambulatory technology to deliver treatment.

Lander R, Heled E, Gur E. Executive functioning and spatial processing in anorexia nervosa: an experimental study and its significance for the allocentric lock theory. Eat Weight Disord 2020; 25:1039-1047. [PMID: 31209765 DOI: 10.1007/s40519-019-00728-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2019] [Accepted: 06/04/2019] [Indexed: 12/28/2022] Open
Abstract
PURPOSE The allocentric lock theory (ALT) suggests that people with eating disorders have difficulties in multisensory integration in two reference frames-egocentric and allocentric, whereby the egocentric, but not allocentric, is impaired. This leads to a distorted body image that contributes to the development and maintenance of the disorder. The current study aimed to explore a facet of the ALT, namely, the visuo-spatial aspect, and its relation to cognitive flexibility in patients with anorexia nervosa (AN). METHODS Fifty-five participants took part in the study: 20 AN patients and 35 controls, matched by age and education. The object perspective taking test (OPTT) and the mental rotation test (MRT), tapping egocentric and allocentric representations, respectively, and a set-shifting task were administered. The brief symptom inventory was used to measure overall levels of distress. RESULTS AN patients showed higher level of distress. They performed poorer on the OPTT and set-shifting task but not on the MRT. The OPTT and MRT were correlated for controls but not for AN patients, while the set-shifting task and body mass index were associated with the OPTT but not with the MRT for the AN patients. CONCLUSIONS The findings support the ALT by demonstrating impaired visual egocentric representations and intact allocentric visual functions in AN patients, with cognitive flexibility associated only with the egocentric frame. Therefore, egocentric frame impairment in AN patients may be influenced by visual perception and cognitive flexibility deficiency. LEVEL OF EVIDENCE Level III: case-control analytic study.

Body image in and out of the lab: Correspondence between lab-based attentional bias data and body shape dissatisfaction experiences in daily life. Body Image 2020; 32:62-69. [PMID: 31778889 DOI: 10.1016/j.bodyim.2019.11.002] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2019] [Revised: 11/12/2019] [Accepted: 11/12/2019] [Indexed: 01/27/2023]
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
Affect and reward are associated with unhealthy eating and weight; however, less research has examined affective predictors of hedonic hunger (i.e., extreme reward responsivity, pleasure toward, and drive for food), particularly among adolescents. Whether symptoms indicative of emotional disturbance increase risk of adverse reward-based eating-related symptoms such as hedonic hunger, is unknown. Such evidence could explain why emotional problems increase risk of eating and weight problems among adolescents, when eating-related health problems often originate. This report examined baseline emotional disorder symptoms, negative urgency (i.e., tendency to act impulsively in response to negative affect), and anhedonia (i.e., loss of interest in activities and decreased pleasure) as prospective predictors of increases in hedonic hunger in adolescents; associations between changes in emotional disturbance problems and hedonic hunger were also examined. Ninth-grade students (N = 2598) from high schools completed paper-and-pencil surveys at baseline and a 1-year follow-up. In a multivariable model controlling for the covariance of emotional problems, higher negative urgency, general anxiety, and obsessive-compulsive symptoms, and lower anhedonia at baseline independently predicted increases in hedonic hunger one year later. Also, increases in negative urgency, general anxiety, and obsessive-compulsive symptoms and decreases in anhedonia independently predicted increases in hedonic hunger. Affect- and reward-related variables may be important contributors to risk of hedonic hunger in adolescence.

Abstract
This review highlights the contributions of Professor Thomas Cash to the scholarship of body image experiences in daily life, including his influence on subsequent research in this field. Cash's arguments for capturing a broad range of state-based body image experiences have been heeded, with recent studies exploring positive body image constructs as well as the more studied negative body image experiences. Appearance comparisons are the most commonly studied contextual influence on body image, and they seem to have a consistent effect. However, the experiences of body image in sexual contexts, and among adolescents, those who are pregnant, or have other physical characteristics that may increase the salience of appearance warrant further attention. Findings generally support Cash's contention that trait body image relates to likelihood and level of experience of body image in daily life, though the moderating effects of trait aspects on state-based relationships remains unclear. The discussion concludes with consideration of the impact of assessment schedules on obtained results. It is also discussed how accumulated knowledge regarding state-based body image experiences may be leveraged in treatment contexts, particularly in light of clear evidence that repeated assessment of body image in daily life increases self-awareness of one's body image characteristics.

Association of anthropometric status, perceived stress, and personality traits with eating behavior in university students. Eat Weight Disord 2019; 24:521-531.

Abstract
PURPOSE We investigated the association of anthropometric status, perceived stress, and personality traits with eating behavior in university students. METHODS The participants, 1546 Japanese university students (964 males, 582 females), completed a questionnaire which asked for their current height and weight, ideal height and weight, eating behaviors, perceived stress, and personality traits. RESULTS Restrained eating was higher in normal-weight participants compared with underweight participants in both males and females (p < 0.001, both males and females). Restrained eating in normal-weight males was significantly lower in normal-weight females (p < 0.001). In addition, normal-weight males reported less stress than normal-weight females (anxiety/uncertainty, p = 0.037; tiredness/physical responses, p < 0.001; autonomic symptoms, p < 0.001; depression/feeling, p < 0.001) and underweight males (tiredness/physical responses, p = 0.018; autonomic symptoms, p = 0.001). Moreover, among normal-weight males, neuroticism was significantly lower compared with normal-weight females (p < 0.001). In multiple regression analysis, male participants revealed positive association between restrained eating and body mass index (β = 0.199, p < 0.001) or body mass index difference (β = - 0.170, p = 0.001). In contrast, female revealed more significant associations between emotional and external eating and perceived stress or personality traits compared with males. CONCLUSIONS These results indicate that associations between eating behavior and anthropometric status or psychological factors are different by each eating behavior, which is partly influenced by gender difference. LEVEL OF EVIDENCE V, cross-sectional descriptive study.

Abstract
Eating disorders (ED), including Anorexia Nervosa (AN), Bulimia Nervosa (BN), and Binge Eating Disorder (BED), are medically dangerous psychiatric disorders of unknown etiology. Accumulating evidence supports a biopsychosocial model that includes genetic heritability, neurobiological vulnerability, and psychosocial factors, such as stress, in the development and maintenance of ED. Notably, stress hormones influence appetite and eating, and dysfunction of the physiological stress response has been implicated in ED pathophysiology. Stress signals also appear associated with food reward neurocircuitry response in ED, providing a possible mechanism for the role of stress in appetite dysregulation. This paper provides a review of some of the interacting psychological, behavioral, physiological, and neurobiological mechanisms involved in the stress response among individuals with ED, and discusses novel neuroimaging techniques to address potential physiological confounds of studying neural correlates of stress in ED, such as calibrated fMRI.
