    Abstract: Purging disorder (PD) was recently included as an otherwise specified feeding or eating disorder (OSFED) in the DSM‐5; however, limited information is available on its prevalence, and its etiology is unknown. Method Data from 1,790 monozygotic and 1,440 dizygotic European American female twins (age range = 18–29 years) from the Missouri Adolescent Female Twin Study were used to investigate prevalence and familial influences for PD. A structured clinical interview assessed lifetime DSM‐IV criteria for eating disorders and PD. After adjustment for age, twin correlations and biometrical twin models were used to estimate familial (i.e., genetic plus shared environmental) influences on PD. Results One hundred and twenty one (3.77%; 95% CI: 3.14, 4.49) women met criteria for lifetime PD. Twin correlations suggested that genetic, shared environmental, and nonshared environmental factors influenced liability to PD. Nonshared environmental factors accounted for 56% [35%, 79%] of the variance in PD. Although familial effects accounted for a significant proportion of variance (44% [21%, 65%] ), it was not possible to disentangle the independent contributions of additive genetic effects (20% [0%, 65%]) and shared environmental effects (24% [0%, 57%] ). Discussion PD is a prevalent form of eating pathology. Familial factors are relevant to the development of PD but do not demonstrate the magnitude of heritable factors found for other eating disorders. © 2015 Wiley Periodicals, Inc.

    Abstract: Little empirical attention has been paid to the DSM‐5 definition of binge‐eating disorder (BED), particularly to the associated features of binge episodes. The present study sought to determine how the associated features and undue influence of weight/shape on self‐evaluation contribute to evidence of a clinically significant eating disorder. Method Secondary analyses were conducted on data ( N  = 80; 76.3% women, 76.3% Caucasian, ages 18–43) collected through an epidemiological study of eating patterns. Descriptive statistics were used to report the sample prevalence of the features, independently and in combination. Correlations and alpha reliability were employed to examine relationships among associated features, distress regarding bingeing, and clinical diagnosis. Regression models and receiver‐operating characteristic (ROC) curves were used to determine the utility of the features for explaining variance in distress. Results Internal consistency reliability for indicators was low, and several features demonstrated low or nonsignificant associations with distress and diagnosis. Feeling disgusted/depressed/guilty was the only unique predictor of distress ( p  = 0.001). For the ROC curves, three features was the best threshold for predicting distress. Discussion Results support the need to refine the features to ensure better detection of clinically significant eating pathology for research inclusion and treatment of the illness. © 2015 Wiley Periodicals, Inc.

    Incremental validity of the episode size criterion in binge‐eating definitions: An examination in women with purging syndromes

    Abstract: Of the two primary features of binge eating, loss of control (LOC) eating is well validated while the role of eating episode size is less clear. Given the ICD‐11 proposal to eliminate episode size from the binge‐eating definition, the present study examined the incremental validity of the size criterion, controlling for LOC. Method Interview and questionnaire data come from four studies of 243 women with bulimia nervosa ( n = 141) or purging disorder ( n = 102). Hierarchical linear regression tested if the largest reported episode size, coded in kilocalories, explained additional variance in eating disorder features, psychopathology, personality traits, and impairment, holding constant LOC eating frequency, age, and body mass index (BMI). Analyses also tested if episode size moderated the association between LOC eating and these variables. Results Holding LOC constant, episode size explained significant variance in disinhibition, trait anxiety, and eating disorder‐related impairment. Episode size moderated the association of LOC eating with purging frequency and depressive symptoms, such that in the presence of larger eating episodes, LOC eating was more closely associated with these features. Neither episode size nor its interaction with LOC explained additional variance in BMI, hunger, restraint, shape concerns, state anxiety, negative urgency, or global functioning. Discussion Taken together, results support the incremental validity of the size criterion, in addition to and in combination with LOC eating, for defining binge‐eating episodes in purging syndromes. Future research should examine the predictive validity of episode size in both purging and nonpurging eating disorders (e.g., binge eating disorder) to inform nosological schemes. © 2016 Wiley Periodicals, Inc.

    Abstract: Atypical anorexia nervosa (AAN) is defined by the symptoms of anorexia nervosa in the presence of “significant weight loss” in individuals who are not underweight. Description of current weight in AAN has been limited, significant weight loss has not been defined, and the distinction between having AAN versus having weight suppression has not been examined. Method Secondary analyses were conducted with data from an epidemiological study of women ( n  = 1,640) and men ( n  = 794). Three definitions of significant weight loss (5, 10, and 15%) for AAN were tested in comparisons with controls and a DSM‐5 eating disorder group (DSM‐5 ED) on measures of eating pathology and clinical significance using ANCOVA and logistic regression, controlling for age and body mass index. Secondary analyses compared AAN to a weight suppressed group (WS‐only) and a cognitive concerns group (COG‐only). Results Across weight loss thresholds, ≥25% of adults with AAN were currently overweight/obese. At the 5% and 10% definitions, AAN was associated with elevated eating pathology and distress relative to controls, WS‐only, and COG‐only in women and men. Women with AAN endorsed less eating pathology and distress than DSM‐5 ED at some weight loss definitions, whereas men with AAN did not differ from DSM‐5 ED in eating pathology or distress. Discussion Results support that even a 5% weight loss, combined with cognitive concerns, may produce a group with a clinically significant eating disorder. AAN was observed in both healthy weight and overweight/obese adults, highlighting the importance of screening for restrictive eating disorders at all weights.

    Psychosocial risk factors for eating disorders

    Abstract: One goal in identifying psychosocial risk factors is to discover opportunities for intervention. The purpose of this review is to examine psychosocial risk factors for disordered eating, placing research findings in the larger context of how etiological models for eating disorders can be transformed into models for intervention. Method: A qualitative literature review was conducted focusing on psychological and social factors that increase the risk for developing eating disorders, with an emphasis on well‐replicated findings from prospective longitudinal studies. Results: Epidemiological, cross‐cultural, and longitudinal studies underscore the importance of the idealization of thinness and resulting weight concerns as psychosocial risk factors for eating disorders. Personality factors such as negative emotionality and perfectionism contribute to the development of eating disorders but may do so indirectly by increasing susceptibility to internalize the thin ideal or by influencing selection of peer environment. During adolescence, peers represent self‐selected environments that influence risk. Discussion: Peer context may represent a key opportunity for intervention, as peer groups represent the nexus in which individual differences in psychological risk factors shape the social environment and social environment shapes psychological risk factors. Thus, peer‐based interventions that challenge internalization of the thin ideal can protect against the development of eating pathology. © 2013 by Wiley Periodicals, Inc.

    Abstract: Pressures for men to conform to a lean, muscular ideal have, in part, contributed to eating disorder and muscle dysmorphia symptoms, yet few programs have been developed and empirically evaluated to help men. This study investigated the acceptability and efficacy of a cognitive dissonance‐based (DB) intervention in reducing eating disorder and muscle dysmorphia risk factors in men with body dissatisfaction. Method Men were randomized to a two‐session DB intervention ( n = 52) or a waitlist control condition ( n = 60). Participants completed validated measures assessing eating disorder risk factors preintervention, postintervention, and at 1‐month follow‐up. Results Program ratings indicated high acceptability. The DB condition demonstrated greater decreases in body‐ideal internalization, dietary restraint, bulimic symptoms, drive for muscularity, and muscle dysmorphia symptoms compared with controls ( p values 〈   .02; between‐condition Cohen's d = .30–1.11) from pre‐ to postintervention. At one‐month follow‐up, the DB condition demonstrated significantly lower scores for all variables ( p values 〈   .03; between‐condition d  = .29–1.16). Body‐ideal internalization mediated intervention outcomes on bulimic and muscle dysmorphia symptoms. Discussion Results support the acceptability and efficacy of The Body Project: More Than Muscles up to 1‐month postintervention and should be examined against active control conditions.

    Abstract: COVID‐19 was associated with significant financial hardship and increased binge eating (BE). However, it is largely unknown whether financial stressors contributed to BE during the pandemic. We used a longitudinal, cotwin control design that controls for genetic/environmental confounds by comparing twins in the same family to examine whether financial hardship during COVID‐19 was associated with BE. Methods Female twins ( N  = 158; M age  = 22.13) from the Michigan State University Twin Registry rated financial stressors (e.g., inability to afford necessities) daily for 49 consecutive days during COVID‐19. We first examined whether financial hardship was associated with BE phenotypes across the full sample. We then examined whether cotwins who differed on financial hardship also differed in BE. Results Participants who experienced greater mean financial hardship across the study had significantly greater dimensional BE symptoms, and participants who experienced greater financial hardship on a given day reported significantly more emotional eating that day. These results were replicated in cotwin control analyses. Twins who experienced more financial hardship than their cotwin across the study reported greater dimensional BE symptoms than their cotwin, and participants who experienced more financial hardship than their cotwin on a given day reported greater emotional eating that day. Results were identical when restricting analyses to monozygotic twins, suggesting associations were not due to genetic confounds. Conclusions Results suggest that BE‐related symptoms may be elevated in women who experienced financial hardship during COVID‐19 independent of potential genetic/environmental confounds. However, additional research in larger samples is needed. Public Significance Little is known regarding how financial difficulties during the COVID‐19 pandemic may have contributed to increased binge eating (BE). We found preliminary evidence that financial hardship during COVID‐19 may be associated with greater rates of BE‐related symptoms even when comparing twins from the same family. While additional research is needed, results suggest that people who experienced financial hardship during COVID‐19 may be at increased risk for BE.

    Abstract: Trait‐level emotion regulation (ER) difficulties are associated with eating disorders (EDs) transdiagnostically. However, little research has examined whether within‐person fluctuations in ER longitudinally predict ED behaviors in daily life or the mechanisms of ER effects. Investigating daily ER could help us better understand why people experience ED behaviors at a given time. We examined whether day‐to‐day changes in adaptive (e.g., cognitive reappraisal) and maladaptive (e.g., rumination) ER longitudinally predicted core ED behaviors (binge eating, purging, dieting) and whether changes in affect mediated effects. Method Female participants ( N = 688) ages 15–30 from the Michigan State University Twin Registry reported their adaptive and maladaptive ER use, negative affect (NA), positive affect (PA), binge eating, purging, and dieting on 49 consecutive days. Using structural equation modeling, we examined whether within‐person fluctuations in ER predicted same‐ and next‐day ED behaviors and whether changes in affect mediated longitudinal ER effects. Results Greater maladaptive ER predicted increased likelihood of same‐day binge eating and next‐day binge eating and purging. The association between maladaptive ER and next‐day binge eating and purging was mediated by increased next‐day NA. In contrast, dieting was more closely related to changes in PA. Adaptive ER did not predict reduced likelihood of any ED behavior. Conclusions Maladaptive ER may longitudinally increase risk for binge eating and purging by amplifying NA. Interventions focused on decreasing maladaptive ER and subsequent NA might help disrupt binge eating‐purging cycles. Conversely, results add to evidence that PA fluctuations may play a unique role in maintaining restrictive behaviors. Public Significance Little is known about how daily changes in emotion regulation may impact disordered eating. We found that maladaptive emotion regulation (e.g., rumination) was associated with a higher likelihood of binge eating and purging on the next day because it predicted increased next‐day negative affect. In contrast, dieting was more closely tied to fluctuations in positive affect. Targeting daily emotion regulation and affective processes may help disrupt cycles of disordered eating.

    Abstract: Social media sites, such as Facebook, merge two factors that influence risk for eating disorders: media and peers. Previous work has identified cross‐sectional and temporal associations between Facebook use and disordered eating. This study sought to replicate and extend these findings using an experimental design. Method In Study 1, 960 women completed self‐report surveys regarding Facebook use and disordered eating. In Study 2, 84 women were randomly assigned to use Facebook or to use an alternate internet site for 20 min. Results More frequent Facebook use was associated with greater disordered eating in a cross‐sectional survey. Facebook use was associated with the maintenance of weight/shape concerns and state anxiety compared to an alternate internet activity. Discussion Facebook use may contribute to disordered eating by maintaining risk for eating pathology. As such, targeting Facebook use may be helpful in intervention and prevention programs. © 2014 Wiley Periodicals, Inc. (Int J Eat Disord 2014; 47:516–523)
