RESUMEN
Emotion differentiation, or the ability to distinguish between discrete emotions in the moment, has been linked to maladaptive behaviors, including disordered eating. Appearance schemas may impact this relationship, as it has been suggested that individuals who are preoccupied with appearance-related information in their environment have limited attentional resources to devote to other internal processes. This study sought to expand existing research by examining: 1) the relationships between emotion differentiation and self-reported eating disorder symptomatology, and 2) strength of implicit appearance schemas as a moderator of these relationships. Participants were 118 female undergraduate students who completed a self-report disordered eating symptomatology questionnaire and a word stem completion task (measuring implicit appearance schemas) at baseline. Participants then reported their daily disordered eating behaviors and emotions through ecological momentary assessment for seven days. Emotion differentiation indices were calculated from negatively-valenced (NED) and positively-valenced (PED) daily affect ratings using intraclass correlation coefficients. Analyses demonstrated significant relationships between NED, severity of eating disorder symptomology, and frequency of compensatory behaviors; however, these relationships did not emerge with PED. Strength of appearance schemas was a moderator, suggesting that poor NED paired with stronger appearance schemas resulted in more severe eating disorder symptoms and more frequent engagement in compensatory behaviors. Multilevel models revealed that better NED predicted daily engagement in dietary restriction. By examining the relationship between emotion differentiation and disordered eating symptoms, this study contributes clinically significant information regarding a facet of emotional experience that may be important to our understanding of eating disorder symptomatology.

BACKGROUND: While presurgical eating behaviors have demonstrated limited prognostic value, cognitions regarding the effects of eating may serve as important predictors of weight loss outcomes after bariatric surgery. The Eating Expectancies Inventory (EEI) is a commonly used, self-report measure of expected consequences of eating; however, its psychometric and predictive properties have not yet been evaluated among bariatric surgery patients. OBJECTIVES: This study sought to examine the factor structure and internal consistency of the EEI among bariatric surgery candidates, to examine relationships between EEI factors and measures of eating psychopathology, and to explore the effects of eating expectancies on postsurgical weight loss. SETTING: Data originated from an interdisciplinary bariatric surgery center in the Midwest United States. METHODS: Two hundred sixty-two women completed self-report questionnaires before bariatric surgery. Presurgical data and available postsurgical weights (at 6, 12, and 18 mo) were obtained from medical records. RESULTS: Analyses indicated that the original 5-factor model was a good-to-excellent fit for the EEI data. All EEI factors demonstrated good reliability and were significantly associated with eating disorder symptoms and behaviors at baseline. Higher scores on EEI Factor 1 (negative affect) and Factor 5 (alleviates boredom) predicted poorer weight loss at 18 months postsurgery (n = 132). CONCLUSIONS: Findings support the reliability and validity of the EEI among female bariatric candidates. Presurgical eating expectancies were linked to pathologic eating patterns and also predicted postsurgical weight loss trajectories, suggesting that eating expectancies may have prognostic value as predictors of bariatric surgery outcomes.

OBJECTIVE: Women who report greater chronic dieting consume more alcohol, drink more frequently, and experience greater problems than women who report less chronic dieting. Alcohol may also temporarily disrupt a woman's dietary rules, leading to increased caloric intake and subsequent restriction. This study examined whether alcohol use mediated the relationship between dietary restraint and alcohol problems in a woman's daily life. PARTICIPANTS: Women (N = 59) completed the study by the fall of 2013. METHODS: Participants completed up to six assessments for 10 days, including intended dietary restraint, alcohol use, and problems. RESULTS: Drinking quantity partially mediated the relationship between dietary restraint and alcohol problems. For each drink consumed, there was a 1.4 times greater likelihood of eating after drinking, which was associated with greater intention to subsequently restrict calories. CONCLUSIONS: The types of drinks consumed and reasons for restricting one's caloric intake may inform the relationship between these behaviors.

BACKGROUND: Many bariatric surgery candidates report body image concerns before surgery. Research has reported post-surgical improvements in body satisfaction, which may be associated with weight loss. However, research has failed to comprehensively examine changes in affective, behavioral, and cognitive body image. OBJECTIVES: This research examined (1) short-term changes in affective, behavioral, and cognitive components of body image from pre-surgery to 1- and 6-months after bariatric surgery, and (2) the association between percent weight loss and these changes. SETTING: Participants were recruited from a private hospital in the midwestern United States. METHODS: Eighty-eight females (original N = 123; lost to follow-up: n = 15 at 1-month and n = 20 at 6-months post-surgery) completed a questionnaire battery, including the Body Attitudes Questionnaire, Body Checking Questionnaire, Body Image Avoidance Questionnaire, and Body Shape Questionnaire, and weights were obtained from patients' medical records before and at 1- and 6-months post-surgery. RESULTS: Results indicated significant decreases in body dissatisfaction, feelings of fatness, and body image avoidance at 1- and 6-months after bariatric surgery, with the greatest magnitude of change occurring for body image avoidance. Change in feelings of fatness was significantly correlated with percent weight loss at 6-months, but not 1-month, post-surgery. CONCLUSIONS: These findings highlight the importance of examining short-term changes in body image from a multidimensional perspective in the effort to improve postsurgical outcomes. Unique contributions include the findings regarding the behavioral component of body image, as body image avoidance emerges as a particularly salient concern that changes over time among bariatric surgery candidates.

This research tested a model that integrates risk factors among non-suicidal self-injury (NSSI) and eating disorder (ED) behaviors with the aim of elucidating possible shared and unique mechanisms underlying both behaviors. Emotional distress, limited access to emotion regulation (ER) strategies, experiential avoidance, and NSSI/ED frequency were examined in a sample of 230 female undergraduates. Structural equation modeling indicated that limited access to ER strategies and avoidance mediated relationship between emotional distress and avoidance, which in turn was associated with NSSI and ED behaviors. Results suggest NSSI and ED behaviors may serve similar emotion regulation functions, and specifically highlight the role of experiential avoidance in these behaviors.

Although a growing body of research has examined Purging Disorder (PD), there remains a lack of conclusive evidence regarding the diagnostic validity of PD. This meta-analysis compared PD to DSM-5 eating disorders (i.e., Anorexia Nervosa [AN], Bulimia Nervosa [BN], and Binge Eating Disorder [BED]) and controls. A comprehensive literature search identified 38 eligible studies. Group differences on indicators of course of illness and both general and eating psychopathology were assessed using standardized effect sizes. Results supported the conceptualization of PD as a clinically significant eating disorder, but findings were less clear regarding its distinctiveness from other eating disorder diagnoses. More specifically, PD significantly differed from BN and BED in natural course of illness (g = .40-.54), and PD significantly differed from AN in treatment outcome (g = .27), with PD characterized by a better prognosis. Overall, PD was more similar to AN and BED on many dimensional measures of general and eating-related psychopathology, though PD was less severe than BN in most of these domains. PD, BN, and BED groups also evidenced similar frequencies of subjective binge episodes (SBEs), yet PD evidenced less frequent SBEs than AN. There is a clear need for future studies of PD to assess validators that have not been reported comprehensively in the literature, such as mortality, medical morbidity, and course of illness. Additionally, empirical classification studies are needed to inform future classifications of PD, particularly with regard to categorical differences between PD and other eating disorders.

BACKGROUND: Eating pathology among bariatric surgery candidates is common and associated with adverse outcomes. However, its assessment is complicated by the inconsistent use of standardized measures. We addressed this by examining the use of the Eating Disorder Diagnostic Scale (EDDS) in a large bariatric sample (N = 343). OBJECTIVES: To evaluate the EDDS among bariatric surgery candidates via examination of: (1) Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision (DSM-IV-TR) and fifth edition (DSM-5) rates of binge eating disorder, bulimia nervosa, and maladaptive eating behaviors, and (2) the relationship between response biases and self-reported eating disorder symptoms. SETTING: Participants were bariatric surgery candidates at a large public hospital in the Midwest. METHODS: As part of a larger preoperative evaluation, 343 patients seeking bariatric surgery completed the EDDS and measures of problematic response bias. RESULTS: Approximately 16% of the sample met full threshold criteria for binge eating disorder using DSM-5 criteria. Using the DSM-IV-TR, rates were lower but still substantial at 13%. Rates for bulimia nervosa were 8% (DSM-5) and 6% (DSM-IV-TR). The majority (66.1%) of participants reported at least one binge-eating episode per week. The most commonly used compensatory behavior was fasting (20.4%), followed by excessive exercise (11.7%), laxative use (5.6%), and vomiting (1.8%). An inverse relationship between severity of the eating symptomatology and problematic response bias emerged. CONCLUSION: The EDDS shows promise as a screening tool that uses diagnostic criteria to provide rates of binge eating and eating psychopathology among surgical candidates. Our findings suggest that subsequent validation studies of this measure are needed, should address potential response bias concerns, and should employ clear definitions of binge eating to promote standardization of eating pathology assessment in the bariatric population.

OBJECTIVE: To investigate social comparison processes as a potential mechanism by which social networks impact young women's weight control thoughts and behaviors and to examine whether social comparisons with close social ties (i.e., friends) have a greater influence on weight control outcomes relative to more emotionally distant ties. METHODS: Using Ecological Momentary Assessment, overweight young adult women (N = 46; M age = 19; M BMI = 29) reported the nature and effects of weight-focused social comparisons on dieting and exercising intentions and on behaviors during their daily routine. RESULTS: Relative to social comparisons to targets of the same weight, weight-focused comparisons to both thinner and heavier individuals led to increased thoughts of dieting and exercising. Moreover, comparisons to thinner targets also increased the likelihood of engaging in actual dieting and exercising behaviors. Weight comparisons to friends amplified these effects. CONCLUSIONS: Weight-focused social comparisons may be one mechanism by which social networks impact weight control thoughts and behaviors. Obesity interventions with young adults may achieve better outcomes by harnessing social comparison processes in treatment.

Fat talk is a style of verbal expression among young women involving negative self-statements, complaints about physical appearance, and weight management. This research used ecological momentary assessment to examine the impact of naturalistic fat talk experiences on body dissatisfaction, body checking, negative affect, and disordered eating behaviors. We examined trait self-objectification as a moderator. Sixty-five female college students completed a baseline questionnaire and responded to questions when randomly prompted by palm pilot devices for five days. Results indicated fat talk is common and associated with greater body dissatisfaction, body checking, negative affect, and disordered eating behaviors. Fat talk participation was associated with greater body checking than overhearing fat talk. Greater trait self-objectification was associated with greater body dissatisfaction and body checking following fat talk. These results suggest that fat talk negatively impacts the cognitions, affect, and behavior of young women and has increased negative effects for women higher in self-objectification.

Within eating disorder treatment programs, a body tracing activity is often used to address body dissatisfaction and overestimation of body size; however, the effects of this activity have never been empirically evaluated. This research examined the effects of body tracing on body dissatisfaction and mood among 56 female participants assigned to either a body tracing or control group. Scores were collected on trait body dissatisfaction and a series of Visual Analogue Scales (VAS). Results showed that trait body dissatisfaction moderated the relationship between group and levels of state appearance dissatisfaction and anxiety. These results suggest that individuals experiencing higher levels of trait body dissatisfaction demonstrated greater state body dissatisfaction following participation in the body tracing activity. Individuals with lower trait body dissatisfaction experienced greater anxiety after drawing a human body. These findings have potential implications for the use of this strategy in the treatment of eating disorder patients.

This research examined the effects of appearance-based comparisons to muscular and slender idealized male bodies and the contribution of internalization and social comparison to change in body dissatisfaction. Participants were 111 male undergraduates who completed measures of body dissatisfaction, internalization, and social comparison and viewed images of either muscular or slender men in advertisements or product-only advertisements. Results indicated that exposure to both muscular and slender images was associated with an increase in body dissatisfaction, with no significant differences in the change in body dissatisfaction between the two image conditions. Internalization and trait social comparison were each associated with an increase in body dissatisfaction; however, upward social comparison was only a significant predictor of a change in body dissatisfaction for the males who viewed muscular images. These results highlight the impact of slender models on young men's body dissatisfaction and support the examination of media literacy interventions with this population.

This research used multilevel modeling to investigate the hypothesis that restrained eaters increase dietary restriction when they expect to drink alcohol. Undergraduate women (39 restrained eaters; 40 unrestrained eaters) monitored their food and alcohol intake for ten days. Restrained eaters, on average, consumed fewer calories per day than unrestrained eaters. Although the intent to drink alcohol did not impact the overall caloric intake of restrained eaters prior to drinking, restrained eaters reported significantly fewer eating episodes than unrestrained eaters on days the participants intended to drink. Given that restrained eaters generally consumed fewer calories per day and had fewer eating episodes prior to drinking, one major implication of higher levels of intoxication would be increased risk of negative alcohol-related consequences. Future research should extend this study and evaluate negative alcohol-related consequences that occur with higher levels of intoxication.

Internalization of societal standards of physical attractiveness (i.e., internalization of the thin ideal for women and internalization of the mesomorphic ideal for men) is a widely studied and robust risk factor for body dissatisfaction and maladaptive body change behaviors. Substantial empirical research supports internalization as both a mediator and a moderator of the relation between societal influences and body dissatisfaction. In this paper, a primer on mediation and moderation is followed by a review of literature and discussion of the extent to which internalization can theoretically fulfill the roles of both mediation and moderation. The literature review revealed a stark contrast in research design (experimental versus non-experimental design) when alternate conceptualizations of internalization are adopted. A meta-theoretical, moderated mediation model is presented. This model integrates previous research and can inform future empirical and clinical endeavors.

Brief interventions encourage college students to eat more before drinking to prevent harm (Dimeff et al., 1999), although many women decrease their caloric intake (Giles et al., 2009) and the number of eating episodes (Luce et al., 2012) prior to drinking alcohol. Participants were 37 undergraduate women (24.3% Caucasian) who were recruited from a local bar district in the Midwest. This study examined whether changes in eating after intending to drink interacted with dietary restraint to predict accuracy of one's intoxication. Results indicated that changes in eating significantly moderated the relationship between dietary restraint and accuracy of one's intoxication level. After eating more food before intending to drink, women higher in restraint were more likely to overestimate their intoxication than women lower in restraint. There were no differences between women with high levels and low levels of dietary restraint in the accuracy of their intoxication after eating less food before intending to drink. Future research would benefit from examining interoceptive awareness as a possible mechanism involved in this relationship.

The present study examined various factors from the interactive and sociocultural models of bulimia nervosa as predictors of the onset of compensatory behaviors. Participants (n=237) completed a series of questionnaires assessing dietary restraint, body dissatisfaction, negative affect, binge eating, perfectionism, and self-esteem at two time points one year apart. Women who did not engage in compensatory behaviors at time one but did engage in compensatory behaviors at time two (n=21) were compared to women who engaged in compensatory behaviors at both time points (n=28) and women who did not engage in compensatory behaviors at either time point (n=188). Body dissatisfaction and perfectionism at time one significantly predicted women who began using compensatory behaviors compared to women who did not engage in compensatory behaviors at either time point. Women who experienced an onset of compensatory behaviors also reported significantly greater body dissatisfaction at time 1 than women who engaged in compensatory behaviors for the duration of the study. Implications and limitations of these findings are discussed.

OBJECTIVE: Purging Disorder (PD) is an understudied pattern of behaviors within the Eating Disorder Not Otherwise Specified (EDNOS) category. Such categorization may suggest that PD is not clinically significant as other eating disorders. However, evidence has suggested that PD is associated with significant impairments in psychosocial functioning and well-being. Despite the apparent clinical significance of PD, it remains to be determined if PD is distinct from other clinically significant eating disorders. The present study sought to assess the phenomenology, clinical significance, and distinctiveness of PD. METHOD: Group scores on measures of eating pathology, body image disturbance, and psychological correlates were compared using MANOVA among a female undergraduate sample (N=94) meeting diagnostic criteria for PD (n=20), Bulimia Nervosa (BN; n=35), restrained eating (n=18), and healthy controls (n=21). RESULTS: Overall, results indicated the PD group reported less severe symptoms than BN but more severe symptoms than controls. The PD and restraint groups were similar on most variables (including subjective binge behavior), with the exception of perfectionism and hunger. DISCUSSION: Findings support the conceptualization of PD as existing along a spectrum of bulimic spectrum disorders rather than as a distinct diagnostic category.

A large body of literature demonstrates the association between body image disturbances and health compromising behaviors among women (e.g., pathological eating, substance use, inappropriate exercise). However, given that disturbed body image is a pervasive problem, it is likely inversely related to health maintenance behaviors. Cancer screenings for breast, skin, and cervical cancer represent an important type of health maintenance behavior, yet adherence rates are low. Given the body-focused nature of these screenings, body image may be a salient predictor. This paper reviews the literature on the relationship between body image disturbances and cancer screening behaviors among women culminating in the proposal of a theoretical model. This model posits that body shame and body avoidance predict performance of cancer screenings and that variables drawn from the cancer literature, including risk perception, health anxiety, subjective norms, and self-efficacy, may moderate this relationship. Clinical implications and suggestions for research are discussed.

AIM: Research suggests that exercise absence is frequently associated with greater guilt and negative affect, particularly when obligatory exercise beliefs and eating disordered psychopathology are considered. Two separate studies used ecological momentary assessment (EMA) to examine differences in mood on exercise and non-exercise days and the moderating impact of obligatory exercise beliefs and eating disordered beliefs and behaviors. METHOD: Both studies recruited female university students who endorsed frequent exercise behavior and study two also recruited based on level of eating disordered psychopathology. Participants completed the Obligatory Exercise Questionnaire at baseline and EMA measures of affect and exercise behavior for approximately one week. Study two participants also completed measures of body dissatisfaction and cognitions. RESULTS: Results of study one suggest that obligation to exercise appears to have a greater impact on general level of affect than does exercise absence or the interaction of these two. In addition, in study two, eating disorder symptomatology was significantly associated with affect and cognition while exercise absence and obligatory exercise beliefs were not. CONCLUSIONS: The present studies suggest that the absence of exercise is not associated with significant changes in affect or cognitions. However, obligation to exercise and eating disorder symptomatology do impact affect and cognitions.
RESUMEN
This research sought to identify factors that may facilitate our understanding of the individual characteristics associated with continuing to engage in non-suicidal self-injury (NSSI) versus stopping the behavior. Participants were 214 undergraduates who currently engaged in NSSI, had a past history of, or never engaged in NSSI. Individuals with a current or past history of NSSI reported significantly more intense emotional experiences, more difficulty identifying their feelings, less access to emotion regulation skills, and significantly greater avoidance than individuals who never engaged in NSSI; additionally, individuals with a past NSSI history reported significantly greater acceptance of their emotional responses and significantly greater impulse control than individuals currently engaging in NSSI. The research and clinical implications of these findings are discussed.

Drawing on Festinger's (1954) social comparison theory and its modern applications, this research investigated the relationship between upward appearance-focused social comparisons and body image disturbance using ecological momentary assessment, which allows for examination of these phenomena in their natural context. Participants were 91 undergraduate women who answered questionnaires five times per day for five days using Palm Personal Data Assistant (PDA) devices. Analyses were conducted using hierarchical linear modeling, which allows for examination of longitudinal data both within and across participants. Results revealed a positive relationship between upward appearance-focused social comparisons and body image disturbance. Upward appearance-focused social comparisons were associated with greater body image disturbance for those with higher levels of thin-ideal internalization and with greater body checking for women with lower levels of feminist beliefs. These findings further illuminate the nature of the relationship between social comparisons and body image disturbance.
