Non-overweight individuals may follow aggressive weight management approaches alongside overweight/obese friends or family members; thus, research has begun to evaluate subsequent effects among non-overweight populations. A prior study evaluated the short-term effects of an immersion weight loss programme on healthy young adult staff leaders. Results indicated that participation seemed to benefit, not harm, the young adults. The current investigation examined 1-year eating disorder and weight trajectories in this sample. The total sample ( N = 244) consisted of staff leaders (44.3%) and demographically similar comparison participants who completed eating disorder and weight assessments across four time points: baseline, end of summer, 6-week follow-up and 1-year follow-up. Forty-seven per cent of the original sample responded to all time points (staff leaders n = 60; comparison n = 55). Over the course of 1 year, risk trajectories did not differ between groups. Staff leaders did not report significant changes in body mass index, suggesting that they maintained healthy weight over the course of 1 year. Participation as an immersion weight loss programme leader appeared to be protective against weight gain, without increasing eating disorder risk, for healthy young adults. This provides further support for using weight management interventions across a wide range of individuals. [ABSTRACT FROM AUTHOR]

The purpose of this paper was to provide examples of physical activities in which children with severe spastic cerebral palsy can participate. These activities were designed in consultation with a physical therapist and used in elementary and middle schools. They included the four-pin stretch, sitting t-ball, hit and move, soccer kick, wheelchair knockdown, and tetherball. Each activity was described and illustrated. Also mentioned was the importance of cooperative planning with allied health personnel and the need to analyze and adapt skills that lead to successful performance. This paper is most useful for practitioners seeking activities that can be safely and successfully employed in an adapted physical education class. It could also serve as supplemental reading for undergraduate physical education majors enrolled in an adapted physical education class. For students, the paper identifies activities that could be utilized in an adapted laboratory experience or included in their adapted physical education activity notebook. [ABSTRACT FROM AUTHOR]

Objective: While weight restoration and/or stabilization is crucial for successful treatment and sustained recovery from restrictive eating disorders (EDs), it is often challenging to define an individual's expected healthy body weight. This paper introduces the TeenGrowth package and its web-based application, designed to calculate and forecast predicted body mass index (BMI) and weight across adolescence., Method: TeenGrowth includes functions for data cleaning, predicted BMI z-score and BMI calculations, and growth forecasting. The accompanying Shiny web application provides a user-friendly interface, enabling the identification of predicted weights for individuals. Through a series of 30 computer-simulated datasets for 1100 individuals (1000 "healthy" and 100 "ED"), the package's options for predictive models are evaluated., Results: Simulation results highlight the potential for use in ED screening and treatment and guide users on modeling options. Prediction of adolescent BMI was more accurate for TeenGrowth models, specifically mean pre-ED BMIz, most recent pre-ED BMIz, or the combination of these metrics (median BMI error for these methods across all simulations = 0.69) when compared to predictions at the 50th percentile of population-based norms (median BMI error = 2.15). Aggregated across simulation approaches, results further support optimal accuracy in identifying ED cases when using mean, most recent, or mean + most recent methods (mean ED case classification accuracy = 0.86) as compared to the use of a population-based metric-85% of the 50th percentile BMI (mean classification accuracy = 0.61)., Discussion: The introduction of TeenGrowth represents a first step towards setting reproducible, personalized predicted body weights for young people., (© 2025 Wiley Periodicals LLC.)

The Body Advocacy Movement (BAM) is a novel, cognitive-dissonance-based intervention designed to target fatphobia and anti-fat bias as mechanisms to drive reductions in eating disorder (ED) risk. Previous dissonance-based programs (i.e. the Body Project; BP) have successfully targeted thin-ideal internalization as an intervention mechanism. As burgeoning research indicates that fatphobia and anti-fat bias may play a central role in the maintenance of ED pathology, a focused intervention designed to target these constructs could bolster prevention efforts. The aims of this pilot study include confirming acceptability and feasibility of BAM and developing preliminary estimates of its effects on intervention targets, along with benchmarking these effects against the BP intervention. BAM was found to be accepted by participants and feasible to facilitate in a peer-led model. Preliminary results from 50 participants (BAM: N  = 26; BP: N  = 24) reveal small-to-moderate pre-to-post intervention effects on fatphobia, anti-fat bias, thin-ideal internalization, and eating pathology, which dissipated at 8-week follow-up. The BAM intervention has the potential to supplement the existing suite of ED prevention programs by specifically targeting anti-fat bias, though additional testing in larger and more diverse samples is necessary to clarify its impact on both hypothesized risk mechanisms and ED outcomes.

Background: Weight stigma among healthcare professionals is associated with negative health impacts on patients, yet there are few effective strategies to combat weight stigma among health professional learners. The Body Advocacy Movement-Health (BAM-Health) is a novel group-based, peer-led stigma reduction intervention for health professional students that targets weight stigma across intrapersonal, interpersonal, and structural levels. The present study (1) assesses short-term impacts of BAM-Health participation on intrapersonal and interpersonal weight bias compared to an informational brochure control condition and (2) explores the feasibility and acceptability of BAM-Health among a sample of health professional students., Methods: Sixty-seven health professional students participated in BAM-Health (n = 34) or received an informational brochure about weight stigma (n = 33). Participants completed validated self-report surveys assessing internalized weight/ appearance concerns and interpersonal weight stigma prior to their assigned intervention (baseline), immediately following intervention (post-intervention), and four weeks after intervention (follow-up). Baseline to post-intervention and baseline to follow-up effect sizes on each measure were calculated. At post-intervention, participants completed feedback surveys for thematic assessment., Results: BAM-Health participation had a large baseline to post-intervention effect on internalized weight/ appearance concerns that diminished slightly at follow-up (Cohen's d = -0.88; d = -0.62). Receipt of the informational brochure had a small effect on internalized weight/ appearance concerns (d = -0.27); however, these changes were not sustained at follow-up (d = 0.04). BAM-Health participation resulted in reductions in interpersonal obesity stigma and anti-fatness with small effect sizes (d = -0.32; d = -0.31). The effect on obesity stigma was slightly amplified at follow-up (d = -0.43); however, decreases in anti-fatness were not sustained (d = -0.13). The brochure condition failed to demonstrate effects on anti-fatness (d = 0.13, d = 0.14) or obesity stigma (d = -0.12; d = -0.12) at either time point. Between-session attrition rates of 4.5%, favorable quantitative ratings on post-session acceptability surveys, and free responses demonstrating appreciation of the virtual group environment and session activities reflect feasibility and acceptability of BAM-Health., Conclusions: BAM-Health is a novel peer-led intervention that aims to reduce weight stigma among health professional students. BAM-Health met feasibility benchmarks and received positive feedback from participants, demonstrating acceptability and indicating interest among health professional students in analyzing and reducing weight stigma in their personal lives and careers. The intervention led to promising decreases in internalized and interpersonal weight stigma at post-intervention, some of which were sustained at follow-up. However, lack of effect on internalized weight/ appearance concerns measures may indicate that BAM-Health participants are more likely to reject weight stigma directed toward others following intervention, while maintaining thin ideals for themselves. Further investigation of BAM-Health with a larger sample and continued program development is warranted., (© 2024. The Author(s).)

Objective: Although exercise is generally considered healthy, many individuals engage in maladaptive exercise (e.g., compulsive in nature). Several definitions of maladaptive exercise exist, leading to multiple, varied assessment tools; assuming homogeneity across these assessments contributes to low consensus in etiological models., Method: We used a Jaccard Index to quantify content overlap among 15 commonly-used self-report instruments measuring maladaptive exercise, with 31 features identified across 224 items., Results: The most common features were exercise to control weight/shape and to avoid negative affect (both included in 9/15 instruments), or compensate for calories consumed (8/15 instruments). Overlap among instruments was low (.206) and no features were common across all instruments., Conclusions: Findings generally support theoretical models of exercise in eating pathology. However, instruments most commonly used to assess maladaptive exercise measure heterogenous content. Careful consideration should be taken when comparing findings derived from differing instruments, when synthesizing literature on maladaptive exercise, and when selecting instruments to measure specific maladaptive exercise features., Public Significance: Many, varied, tools exist for the assessment of maladaptive exercise (e.g., compulsive or compensatory) in the context of eating disorders. Assuming homogeneity across tools contributes to low consensus in the field. We used a Jaccard Index to quantify content overlap among 15 self-report instruments measuring maladaptive exercise. The most commonly used instruments measure heterogenous content. Careful consideration should be taken when synthesizing literature and selecting instruments to use in research., (© 2024 Wiley Periodicals LLC.)

While exercise is generally associated with positive health outcomes, in the context of eating disorders, exercise has high potential to become maladaptive. Maladaptive exercise is compelled or compulsive in nature for the purposes of weight and shape control or to obtain/avoid other eating disorder-relevant consequences. A transdiagnostic eating disorder feature with moderate-to-high prevalence across restrictive- and bulimic-spectrum eating disorders, maladaptive exercise is often associated with negative mental and physical health sequalae. Several proposed threat- and reward-related biobehavioral mechanisms may initiate or perpetuate maladaptive exercise. While exercise is generally contraindicated during periods of acute medical concern, adaptive forms of exercise are also present among those with eating disorders, and facilitation of adaptive exercise has potential to promote physical and mental health benefits during eating disorder recovery. Detailed assessment and targeted interventions are needed to address the clinical conundrum of how and when to integrate exercise into eating disorder treatment., (© 2024.

Background: Exercise for weight loss and maladaptive exercise (exercise that results in negative consequences or interference with daily life) are common behaviors among youth and are associated with increased risk of disordered eating symptoms. The current study clarifies processes that influence exercise-related risk in adolescence and young adulthood, including the frequency with which young people transition between engaging in exercise for weight loss and experiencing negative consequences of this behavior., Method: Participants from the Avon Longitudinal Study of Parents and Children (ALSPAC) reported on eating disorder cognitions at age 14, and exercise behavior at ages 14, 16, 18, and 24 years old. Analyses examined rates of transition between the categories of 'No Exercise for Weight Loss', 'Exercise for Weight Loss', and 'Maladaptive Exercise' over time, identified overall trends in endorsement of exercise for weight loss and maladaptive exercise, and clarified predictors of these behaviors., Results: Endorsement of exercise for weight loss and maladaptive exercise increased over time in both males and females. Those in the 'Exercise for Weight Loss' category were more likely than those in the 'No Exercise for Weight Loss Category' to transition to 'Maladaptive Exercise' over time. Body mass index (Age 13) and fear of weight gain (Age 14) were consistent predictors of maladaptive exercise across sex., Conclusions: Results support re-framing motivations for exercise in youth away from weight loss at a population level and targeting reductions in fear of weight gain for high-risk individuals., (© 2023 The Authors.

Background: Clinical, epidemiological, and genetic findings support an overlap between eating disorders, obsessive-compulsive disorder (OCD), and anxiety symptoms. However, little research has examined the role of genetics in the expression of underlying phenotypes. We investigated whether the anorexia nervosa (AN), OCD, or AN/OCD transdiagnostic polygenic scores (PGS) predict eating disorder, OCD, and anxiety symptoms in a large developmental cohort in a sex-specific manner., Methods: Using summary statistics from Psychiatric Genomics Consortium AN and OCD genome-wide association studies, we conducted an AN/OCD transdiagnostic genome-wide association meta-analysis. We then calculated AN, OCD, and AN/OCD PGS in participants from the Avon Longitudinal Study of Parents and Children to predict eating disorder, OCD, and anxiety symptoms, stratified by sex (combined N = 3212-5369 per phenotype)., Results: The PGS prediction of eating disorder, OCD, and anxiety phenotypes differed between sexes, although effect sizes were small. AN and AN/OCD PGS played a more prominent role in predicting eating disorder and anxiety risk than OCD PGS, especially in girls. AN/OCD PGS provided a small boost over AN PGS in the prediction of some anxiety symptoms. All three PGS predicted higher compulsive exercise across different developmental timepoints [ β = 0.03 (s.e. = 0.01) for AN and AN/OCD PGS at age 14; β = 0.05 (s.e. = 0.02) for OCD PGS at age 16] in girls., Conclusions: Compulsive exercise may have a transdiagnostic genetic etiology, and AN genetic risk may play a role in the presence of anxiety symptoms. Converging with prior twin literature, our results also suggest that some of the contribution of genetic risk may be sex-specific.

Objective: There is increasing consensus that open science practices improve the transparency and quality of clinical science. However, several barriers impede the implementation of these practices at the individual, institutional, and field levels; understanding and addressing these barriers is critical to promoting targeted efforts in increasing effective uptake of open science., Methods: Within this research forum, we drew from publicly available online information sources to identify initial characterizations of researchers engaged in several types of open science practices in the field of eating disorders. We use these observations to discuss potential barriers and recommendations for next steps in the promotion of these practices., Results: Data from online open science repositories suggest that individuals using these publishing approaches with pre-prints and articles with eating-disorder-relevant content are predominantly non-male gender identifying, early to mid-career stage, and are more likely to be European-, United States-, or Canada-based., Discussion: We outline recommendations for tangible ways that the eating disorder field can support broad, increased uptake of open science practices, including supporting initiatives to increase knowledge and correct misconceptions; and prioritizing the development and accessibility of open science resources., Public Significance Statement: The use of open science practices has the potential to increase the transparency and quality of clinical science. This Forum uses publicly sourced online data to characterize researchers engaged in open science practices in the field of eating disorders. These observations provide an important framework from which to discuss potential barriers to open science and recommendations for next steps in the promotion of these practices., (© 2023 Wiley Periodicals LLC.)

Maladaptive exercise (i.e., exercise that compensates for binge eating or is used to avoid negative consequences of not exercising-like weight gain) is a common eating disorder (ED) behavior, yet, some individuals with EDs only engage in adaptive exercise. CBT for EDs targets reducing maladaptive exercise but does not address adaptive exercise. Thus, research is limited on how adaptive and maladaptive exercise are impacted during CBT for EDs. The current study examined how assessor-rated adaptive and maladaptive exercise and objectively measured physical activity changed over a 12-week CBT treatment among adults with transdiagnostic binge eating and restrictive eating that did and did not engage in maladaptive exercise at the start of treatment (n = 13 non-maladaptive exercise group, n = 17 maladaptive exercise group). The overall amount of adaptive and maladaptive exercise was measured via the Eating Disorder Examination Interview and objectively measured physical activity (e.g., step count, minutes of moderate-to-vigorous physical activity [MVPA]) was measured via a wrist-worn fitness tracker. Throughout treatment, the overall amount of adaptive exercise did not significantly change for both groups, but the overall amount of maladaptive exercise significantly decreased in the maladaptive exercise group. Step count did not significantly change for both groups, but minutes of MVPA significantly increased over treatment for the non-maladaptive exercise group. Increases in step count and minutes of MVPA were not associated with ED symptom changes in either group. These results enhance an understanding of exercise changes during transdiagnostic CBT-based ED treatment for individuals with varying baseline exercise profiles.Level of evidence: Level 1, randomized controlled trial., (© 2023.

Wearable fitness trackers are an increasingly popular tool for measuring physical activity (PA) due their accuracy and momentary data collection abilities. Despite the benefits of using wearable fitness trackers, there is limited research in the eating disorder (ED) field using wearable fitness trackers to measure PA in the context of EDs. Wearable fitness trackers are often underused in ED research because there is limited knowledge about whether wearable fitness trackers negatively or positively impact PA engagement and ED symptoms in individuals with EDs. The current study aimed to assess the perceived impact wearable fitness trackers have on PA engagement and ED symptoms over a 12-week CBT treatment for 30 individuals with binge eating and restrictive eating that presented to treatment engaging or not engaging in maladaptive exercise. Participants in the maladaptive exercise group (n = 17) and non-maladaptive exercise group (n = 13) wore a fitness tracker for 12 weeks and completed questionnaires assessing participants' perceptions of the fitness trackers' influence on ED symptoms and PA engagement throughout treatment. Results demonstrated a small percentage of individuals perceived the fitness tracker influenced ED behaviors or PA engagement, and there were mixed results on whether participants positively or negatively perceived the fitness tracker influenced them to engage in ED behaviors or PA engagement. Although preliminary, these results demonstrate the need to continue using objective measurements of PA via wearable fitness trackers to further our understanding of the positive and negative effects of fitness trackers on clinical ED samples.Level of Evidence: Level 1, randomized controlled trial., (© 2022.

Deficits in social cognition and communication, the processes associated with human social behavior and interaction, have been described in individuals with eating disorder psychopathology. The current study examined whether social communication characteristics present in middle childhood (ages 8-14) were associated with eating disorder behaviors, cognitions, and diagnoses across adolescence (ages 14-18) in a large, population-based sample. Participants (N = 4864) were children enrolled in the Avon Longitudinal Study of Parents and Children (ALSPAC), a population-based, prospective study of women and their children. Regression methods tested prospective associations between social functioning using a facial emotion recognition task and parentally reported social communication symptoms (or difficulties), measured by the Social Communication Disorder Checklist (SCDC), with eating disorder symptoms and diagnoses. Misattribution of faces as sad or angry at age 8.5 was associated with purging and anorexia nervosa diagnosis at age 14, respectively, among girls. Furthermore, autistic-like social communication difficulties during middle childhood were associated with bulimia nervosa symptoms during adolescence among both girls and boys. Results did not support global associations between measured social communication deficits and eating disorder risk in this sample, but specific difficulties with facial emotion recognition and social communication may enhance the risk for disordered eating behaviors., (© 2020.

Objective: Driven exercise (DEx) is a serious and common feature of eating disorders (EDs), but current understanding of factors that give rise to and maintain DEx is limited. DEx may be reinforced through its effects on the threat reduction and reward systems. The current protocol is designed to evaluate acute psychobiological response to exercise among female participants (age 16-22) with and without EDs., Method: Twenty medically-stable participants with restrictive-spectrum EDs and 20 healthy control (HC) participants will complete study screening and three task visits which will include two 30-minute bouts of aerobic exercise., Results: We aim to validate and demonstrate feasibility of two tasks capturing exercise response in this sample. Further, we will estimate the degree to which a bout of exercise impacts state body image, affect, and circulating concentrations of biological markers among participants, and we will examine whether the impact of exercise on psychological outcomes may differ across ED and HC groups., Discussion: Completion of this project will contribute to the conceptualization of DEx and how individuals' acute biological and affective responses to exercise contribute to risk for and maintenance of DEx., (© 2021 Wiley Periodicals LLC.)

The tripartite influence model suggests that appearance pressures from family, peers, and the media contribute to thin-ideal internalization, which leads to increased body dissatisfaction and subsequent eating disorder pathology. The tripartite influence model was initially developed and tested among primarily White samples, and emerging research suggests racial/ethnic differences in mean levels of particular model constructs. Consequently, the model's appropriateness for understanding eating disorder risk in racial/ethnic minorities warrants investigation to determine its usefulness in explicating eating disorder risk in diverse populations. Participants in the current study were White (n = 1167), Black (n = 212), Latina (n = 203), and Asian (n = 176) women from five geographically disparate college campuses in the United States. Participants completed the Sociocultural Attitudes Towards Appearance Questionnaire-4, the Multidimensional Body-Self Relations Questionnaire - Appearance Evaluation Subscale, and the Eating Disorder Examination-Questionnaire. Analysis of variance was used to compare mean levels of each construct across racial/ethnic groups. Multigroup structural equation modeling was used to assess the appropriateness of the tripartite influence model for each racial/ethnic group, and to examine differences in the strength of the model pathways across groups. There were significant mean level differences across groups for most model constructs. However, results indicated similar model fit across racial/ethnic groups, with few differences in the strength of model pathways. Findings suggest that although some groups report lower levels of proposed risk factors, the sociocultural risk processes for eating pathology identified through the tripartite influence model are similar across racial/ethnic groups of young adult women. Such information can be used to inform culturally-sensitive interventions., (Copyright © 2021 The Authors. Published by Elsevier Ltd.. All rights reserved.)

Anxiety and eating disorders (EDs) often co-occur, prompting calls to explore anxiety-related maintenance processes in ED samples. Safety behaviors, which function to prevent a feared outcome from occurring or to reduce anxiety associated with a feared stimulus, are observed across anxiety disorders and, along with overt avoidance behaviors, are an important target in treatment. Data suggest that individuals with EDs also engage in safety behaviors. However, no existing assessments provide a comprehensive measure of eating-disorder-specific overt avoidance and safety behaviors. The goal of this Stage 1 Registered Report is to develop a comprehensive self-report measure of ED-specific safety behaviors. In Study 1, we will recruit 50 women with EDs to complete the scale and provide feedback on the response scale. Feedback from these participants will be used to refine the measure. In Study 2, we will evaluate the psychometric properties of the measure in a large sample of women with EDs (n dependent on the size of measurement) and a community sample without current or a history of ED symptoms. We will explore the measure factor structure, known-groups validity by comparing scores from women with EDs to healthy controls, internal consistency, and convergent and divergent validity with other psychological instruments., (© 2021 Wiley Periodicals LLC.)

Purpose: Cognitive rumination is a transdiagnostic construct that has been increasingly studied in the context of eating disorders (EDs). While this literature has consistently linked trait-level general and ED-specific forms of rumination to ED psychopathology, it is not clear whether trait-level measures are independently related to symptoms in daily life. Therefore, the present study used ecological momentary assessment (EMA) to assess the ecological validity of trait measures of general rumination and ED-specific rumination, and assess the degree to which ruminative brooding and reflection were differentially related to relevant momentary affective, cognitive, and behavioral processes., Methods: Forty women completed baseline measures (Ruminative Response Scale [RRS] and Ruminative Response Scale for Eating Disorders [RRSED]) followed by a 10-day EMA protocol., Results: Generalized estimating equations indicated trait-level ED-specific rumination was related to momentary general and ED-specific rumination, and trait-level general and ED-specific rumination were related to momentary affect and concentration difficulties. Trait-level general rumination was related to momentary self-discrepancy, while higher trait-level ED-specific rumination was related to greater loss of control eating, overeating, and body dissatisfaction. Lastly, trait levels of ruminative brooding, compared to reflection, were more consistently related to maladaptive momentary symptoms (i.e., general rumination, negative affect, concentration problems, body dissatisfaction)., Conclusion: Together these findings support the ecological validity of the RRSED and identify shared and unique momentary correlates of the RRS and RRSED. Results also highlight the importance of measuring and addressing trait- and state-level ruminative processes that are both general and specific to ED psychopathology in research and clinical work., Level of Evidence: Level V, observational descriptive study.

Eating disorders (EDs) and anxiety disorders (ADs) evidence shared risk and significant comorbidity. Recent advances in understanding of anxiety-based disorders may have direct application to research and treatment efforts for EDs. The current review presents an up-to-date, behavioral conceptualization of the overlap between anxiety-based disorders and EDs. We identify ways in which anxiety presents in EDs, consider differences between EDs and ADs relevant to treatment adaptions, discuss how exposure-based strategies may be adapted for use in ED treatment, and outline directions for future mechanistic, translational, and clinical ED research from this perspective. Important research directions include: simultaneous examination of the extent to which EDs are characterized by aberrant avoidance-, reward-, and/or habit-based neurobiological and behavioral processes; improvement in understanding of how nutritional status interacts with neurobiological characteristics of EDs; incorporation of a growing knowledge of biobehavioral signatures in ED treatment planning; development of more comprehensive exposure-based treatment approaches for EDs; testing whether certain exposure interventions for AD are appropriate for EDs; and improvement in clinician self-efficacy and ability to use exposure therapy for EDs., (Copyright © 2020 Elsevier Ltd.

As aesthetic athletes, professional dancers have increased vulnerability for eating disorders (EDs), with three times higher risk than non-dancers. Among ballet dancers, generalized risk for EDs associated with internalization of western cultural female beauty ideals is compounded by idealization of a ballet-specific body ideal, a combination that confers unique vulnerability for eating pathology. Empirical support has been established for an athlete-specific intervention promoting body acceptance and reduced eating pathology among general populations of young-adult women and female collegiate athletes; the current study adapted this intervention for pilot implementation among professional ballet dancers. Participants from two elite ballet companies ( N = 19) were randomized to a control and intervention condition. All participants self-reported eating pathology and related variables pre- and post-intervention, and at six-week follow-up. Post-intervention, participants receiving the intervention demonstrated reductions in body dissatisfaction, p = .005, r = -.63, dietary restraint, p = .008, r = -.59, and eating pathology, p = .007, r = -.60, as compared to control group counterparts; significant differences were retained at follow-up. Results provide preliminary evidence that this intervention has the potential to provide a feasible and acceptable means of ED prevention in female professional ballet dancers. Barriers to feasibility are identified and discussed.

Objective: The Criterion B binge-eating symptoms represent five symptoms associated with binge eating. Any three out of five symptoms can be used to meet Criterion B. However, Criterion B symptoms may not be interchangeable in terms of how binge-eating severity is associated with each symptom. Item response theory (IRT) can test how endorsing each symptom relates to the overall level (i.e., severity) of binge-eating measured by Criterion B. We used IRT to identify (a) how each Criterion B symptom corresponded with binge-eating severity in a transdiagnostic binge-eating sample and (b) how well each symptom differentiated individuals with differing levels of severity., Method: Participants (N = 219) were adults (80.8% female) with a current ED that included objective binge-eating episodes assessed via semi-structured interview. A two-parameter logistic IRT model evaluated how endorsement of each Criterion B symptom corresponded with the level of latent binge-eating severity., Results: "Eating large amounts when not hungry" and "eating alone" reflected the highest binge-eating severity. "Eating alone" was the best discriminator across different binge-eating severity levels, whereas "uncomfortably full" was the poorest discriminator across binge-eating severity levels., Discussion: Criterion B symptoms were not interchangeable in terms of what level of binge-eating severity corresponded with symptom endorsement. "Eating large amounts when not hungry" or "eating alone" may signify elevated binge-eating severity, whereas "uncomfortably full" and "feeling disgusted/depressed/guilty" were not necessarily indicative of elevated severity. Results suggested that Criterion B may need to be revised to eliminate symptoms that are redundant with other binge-eating diagnostic criteria., (© 2020 Wiley Periodicals LLC.)

Posttraumatic stress disorder (PTSD) is characterized by heightened avoidance, cognitive inflexibility, and impaired reward processing. Maladaptive behavior in PTSD may reflect an imbalance between approach and avoidance, but no research has investigated approach-avoidance conflict (AAC) in PTSD. The current study investigated approach-avoidance behavior in PTSD using a trauma-related AAC (trAAC) task in two independent samples. In Study 1, 43 women with a current diagnosis of PTSD and 18 healthy comparison subjects were recruited from the community. In Study 2, 53 women with trauma exposure and a range of PTSD symptoms were recruited from a correctional institution. Trials were separated into two phases: conflict (the option most likely to win points was most likely to show a trauma-related image) and congruent (the option most likely to win points was least likely to show a trauma-related image). In Study 1, reward obtainment varied with the task manipulation (i.e., fewer points earned during conflict compared to congruent Phase) in PTSD but not healthy subjects. These results indicate that when avoidance is advantageous (congruent phase), individuals with PTSD show increased task performance, whereas when avoidance is maladaptive (conflict phase), individuals with PTSD show increased sacrifice of reward. In Study 2, higher PTSD symptoms predicted decreased reward earning during the conflict phase, again indicating a sacrifice of reward when avoidance is maladaptive. Across both studies, PTSD associated with increased AAC and sacrifice of reward in the presence of trauma-related stimuli. These studies shed light on AAC in PTSD and could inform more targeted therapy approaches. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

While facets of both anxiety and impulsivity appear central to the development and maintenance of bulimia nervosa (BN), specific BN behaviors may be propagated by differing profiles of risk. The current study examined associations between dimensions of anxiety and impulsivity and BN symptoms (binge eating, vomiting, laxative misuse, driven exercise), both in terms of the presence of such behaviors and their frequency. Two hundred and four women (M age  = 25.7 years) who met DSM-IV criteria for full or subthreshold BN completed self-report measures of perfectionism (Frost Multidimensional Perfectionism Scale), anxiety (Spielberger Trait Anxiety Inventory), impulsivity (Barratt Impulsiveness Scale-11; Impulsive Behavior Scale), eating disordered behaviors (Eating Disorder Examination - Questionnaire), and associated psychiatric symptoms (Michigan Assessment Screening Test/Alcohol-Drug; Maudsley Obsessive-Compulsive Inventory). Factor analysis revealed multidimensional impulsive and anxiety-related traits (5 anxiety-related factors; 7 impulsivity-related factors). In zero-sensitive regression models, different facets of impulsivity evidenced association with the presence of binge eating (risk taking), laxative misuse (impulsive spending), and fasting (difficulty concentrating), along with the frequency of vomiting (long-term planning difficulties). In contrast, anxiety-related dimensions were only associated with driven exercise (high standards) and fasting (concern over mistakes, high standards, parental expectations). Overall, impulsive and anxiety-related factors and symptoms showed distinct associations with specific eating disorder behaviors, even among those with the same diagnosis., (Copyright © 2020 Elsevier Ltd.

Objective: Cross-sectional associations between eating disorders (EDs) and deficits in neuropsychological functioning have been well documented; however, limited research has examined whether neuropsychological functioning is prospectively associated with EDs. The current study investigated prospective associations between neuropsychological functioning in childhood (ages 8 and 10) and ED behaviours and disorders in adolescence (at ages 14, 16, and 18 years) in a population-based sample., Method: Participants (N = 4,803) were children enrolled in the Avon Longitudinal Study of Parents and Children, a population-based, prospective study of women and their children. Regression methods tested associations between facets of neuropsychological functioning (attention, working memory, and inhibition) and eating disorder symptoms and diagnoses., Results: Better scores on working memory tasks in childhood were associated with decreased risk of fasting but increased risk of excessive exercise during adolescence. Better inhibitory control was associated with decreased risk for disordered eating at age 14, and attentional difficulties were associated with increased risk for binge eating disorder during adolescence among boys but not girls., Conclusions: Neuropsychological functioning may enhance risk for disordered eating behaviours in specific ways. Overall, effect sizes were small, and results did not support global associations between neuropsychological differences and ED risk in this sample., (© 2020 John Wiley & Sons, Ltd and Eating Disorders Association.)

Objective: Maladaptive exercise relates to eating disorder (ED) pathology and impairment in clinical and non-clinical populations. At present, two different conceptualizations of maladaptive exercise are often studied in relation to ED pathology: compulsive exercise and exercise dependence. Compulsive exercise functions to avoid negative affect (e.g., guilt and anxiety) associated with not exercising, whereas exercise dependence is associated with tolerance to exercise benefits and avoidance of exercise withdrawal. At present, clinicians and researchers struggle to determine the most appropriate term for describing problematic exercise in individuals with ED pathology. This study aimed to directly compare these conceptualizations of maladaptive exercise in relation to severity of ED pathology., Design: This study examined cross-sectional data., Method: Undergraduate participants ( N =235, 78% female) with elevated ED pathology completed the Eating Disorder Examination Questionnaire (EDE-Q), Compulsive Exercise Test (CET), and Exercise Dependence Scale (EDS). Multiple linear regression analyses evaluated associations between EDE-Q and CET and EDS scores and dominance analysis determined which qualities of exercise were uniquely associated with EDE-Q scores., Results: Results suggest that compulsive qualities of exercise, including exercise to control shape and weight and to avoid negative affect are more strongly associated with severity of ED pathology than qualities of exercise dependence., Conclusions: Clinicians and researchers working with ED populations can benefit from prioritizing assessments that capture compulsive qualities of exercise. Additionally, these results suggest that interventions that effectively target other compulsive behaviors (e.g., exposure and response prevention) may be promising treatment options for problematic exercise in the context of EDs.

Researchers have observed variation in levels of body image disturbance and eating pathology among women from different Western countries. Examination of cross-cultural differences in the established risk factors (i.e., thin-ideal internalization, muscular-ideal internalization, and appearance pressures from family, peers, and media) for negative outcomes may help to elucidate the prominence of specific risk factors within a given Western society and guide associated interventions. Women from the United States (US), Italy, England, and Australia completed the Sociocultural Attitudes Towards Appearance Questionnaire-4 (SATAQ-4). Analysis of covariance controlling for age and BMI indicated significant cross-country differences for all SATAQ-4 subscales. Results typically indicated higher levels of appearance-ideal internalization and appearance pressures in the US and lower levels in Italy; however, associated effect sizes were generally small. A medium effect of country was observed for peer-appearance pressures, which were highest in the US compared with all other countries. Repeated-measures analysis of variance and paired samples t tests conducted within each country identified thin-ideal internalization and media appearance pressures as the predominant risk factors for all four countries. Overall, findings suggest more cross-country similarities than differences, and highlight the importance of delivering interventions to address thin-ideal internalization and media appearance pressures among women from Western backgrounds.Level of evidence Descriptive study, Level V.

This cross-sectional study explored similarities and differences between heterosexual, bisexual, and lesbian women in levels of, and relationships between, the following constructs using a Tripartite Influence Model framework: family, peer, and media appearance pressures, thin- and muscular-ideal internalization, and eating disorder (ED) pathology. Self-identified heterosexual (n = 1,528), bisexual (n = 89), and lesbian (n = 278) undergraduate women completed the Sociocultural Attitudes Towards Appearance Questionnaire-4 and the Eating Disorder Examination-Questionnaire. Sexual orientation differences in appearance pressures, appearance-ideal internalization, and ED pathology were examined via analysis of variance tests. Relationships between these variables were examined with multi-group path analyses, controlling for age, race/ethnicity, and body mass index. Compared with lesbian women, heterosexual and bisexual women reported higher levels of peer appearance pressures. Paths from peer appearance pressures and thin-ideal internalization to shape/weight overvaluation and body dissatisfaction were strongest for bisexual women. Overall, results indicate notable similarities between heterosexual, bisexual, and lesbian women. However, preliminary evidence for potential differences highlights the importance of examining variation in ED risk between sexual minority subgroups., (Copyright © 2019 Elsevier Ltd.

Background: Cross-sectional associations between anxiety disorders and eating disorders (EDs) have been well documented; however, limited research has examined whether symptoms of anxiety disorders are prospectively associated with EDs. Identifying these longitudinal associations can aid in discerning relationships among eating and anxiety disorders and point toward a mechanistic understanding of developmental psychopathology. This study investigated the prospective associations between parent-reported anxiety in mid-childhood (age 10) and child-reported ED behaviors and disorders in adolescence (at ages 14 and 16 years) in a population-based sample., Methods: Participants were individuals enrolled in the Avon Longitudinal Study of Parents and Children (ALSPAC), a population-based, prospective study of women and their children; 7,767 children whose parents provided data at age 10 were included in current analyses. An exploratory factor analysis identified latent anxiety factors at age 10, followed by a path analysis that evaluated associations between these factors and eating disorder symptoms and cognitions at age 14., Results: Parent-reported anxiety symptoms at age 10 yielded 5 factors: obsessive-compulsive disorder (OCD) symptoms related to symmetry and checking (Factor 1); OCD symptoms associated with aversion to dirt and germs (Factor 2); physical anxiety symptoms (Factor 3); worries (Factor 4); and social phobia symptoms (Factor 5). Factors 3 and 4 showed the most consistent, positive associations with a range of ED symptoms at age 14. Factor 3 predicted diagnosis of bulimia nervosa by age 16 (OR = 1.11, p = .007), whereas Factor 4 predicted diagnoses of anorexia nervosa (OR = 1.10, p = .01) and disordered eating by age 16 (OR = 1.08, p = .001)., Conclusions: Results indicate that symptoms of generalized anxiety in middle childhood may predict adolescent-onset ED symptoms and ED diagnoses., (© 2018 Association for Child and Adolescent Mental Health.)

Background: Transition across eating disorder diagnoses is common, reflecting instability of specific eating disorder presentations. Previous studies have examined temporal stability of diagnoses in adult treatment-seeking samples but have not uniformly captured initial presentation for treatment. The current study examines transitions across eating disorder diagnostic categories in a large, treatment-seeking sample of individuals born in Sweden and compares these transitions across two birth cohorts and from initial diagnosis., Methods: Data from Swedish eating disorders quality registers were extracted in 2013, including 9622 individuals who were seen at least twice from 1999 to 2013. Patterns of remission were examined in the entire sample and subsequently compared across initial diagnoses. An older (born prior to 1990) and younger birth cohort were also identified, and analyses compared these cohorts on patterns of diagnostic transition., Results: Although diagnostic instability was common, transition between threshold eating disorder diagnoses was infrequent. For all diagnoses, transition to remission was likely to occur following a diagnosis state that matched initial diagnosis, or through a subthreshold diagnostic state. Individuals in the younger cohort were more likely to transition to a state of remission than those in the older cohort., Conclusions: Results indicate more temporal continuity in eating disorder presentations than suggested by previous research and highlight the importance of early detection and intervention in achieving remission.

Weight suppression (WS) refers to the discrepancy between highest adult weight and current weight, and has been examined as a key construct related to both: eating pathology and weight management. However, despite increasing interest in WS, findings regarding the clinical implications of WS are often conflicting. For instance, WS has been associated with both adaptive and maladaptive outcomes across various populations. Moreover, results regarding the predictive utility of WS within clinical samples have been inconsistent. The current paper aims to provide a narrative review of existing investigation related to WS, highlight gaps in the field's understanding of this construct, and outline recommendations for future study.

Objective: Evidence suggests that eating disorders (EDs) may be under-detected in males. Commonly used measures of EDs such as the Eating Disorder Examination-Questionnaire (EDE-Q) were initially developed within female samples, raising concern regarding the extent to which these instruments may be appropriate for detecting EDs in males. The current study used receiver operating characteristic curve analysis to (a) examine the accuracy of the EDE-Q global score in correctly classifying males with and without clinically significant ED pathology, and (b) establish the optimal EDE-Q global clinical cutoff for males., Method: Participants were a clinical sample of 245 male ED patients and a control sample of 205 male undergraduates., Results: Eating Disorder Examination-Questionnaire global scores demonstrated moderate-high accuracy in predicting ED status (area under the curve = 0.85, 95% CI: 0.82-0.89). The optimal cutoff of 1.68 yielded a sensitivity of 0.77 and specificity of 0.77., Discussion: Overall, results provide preliminary support for the discriminant validity of EDE-Q scores among males. However, concerns remain regarding the measure's ability to comprehensively assess domains of disordered eating most relevant to males. Therefore, careful attention to the possibility for measurement bias and continued evaluation of the scale in males is encouraged., (© 2018 Wiley Periodicals, Inc.)

Objective: Outcome variables gauging the frequency of specific disordered eating behaviors (e.g., binge eating, vomiting) are common in the study of eating and health behaviors. The nature of such data presents several analytical challenges, which may be best addressed through the application of underutilized statistical approaches. While zero-sensitive models are well-supported by methodologists, application of these models has yet to gain traction among a widespread audience of researchers who study eating-related behaviors. The current study examined several approaches to predicting count-based behaviors, including zero-sensitive (i.e., zero-inflated and hurdle) regression models., Method: Exploration of alternative models to predict eating-related behaviors occurred in two parts. In Part 1, participants (N = 524; 54% female) completed the Eating Disorder Examination-Questionnaire and Daily Stress Inventory. We considered the theoretical basis and practical utility of several alternative approaches for predicting the frequency of binge eating and compensatory behaviors, including ordinary least squares (OLS), logistic, Poisson, negative binomial, and zero-sensitive models. In Part 2, we completed Monte Carlo simulations comparing negative binomial, zero-inflated negative binomial, and negative binomial hurdle models to further explore when these models are most useful., Results: Traditional OLS regression models were generally a poor fit for the data structure. Zero-sensitive models, which are not limited to traditional distribution assumptions, were preferable for predicting count-based outcomes. In the data presented, zero-sensitive models were useful in modeling behaviors that were relatively rare (laxative use and vomiting, 9.7% endorsed) along with those that were somewhat common (binge eating, 33.4% endorsed; driven exercise, 40.7% endorsed). Simulations indicated missing data, sample size, and the number of zeros may impact model fit., Discussion: Zero-sensitive approaches hold promise for answering key questions about the presence and frequency of common eating-related behaviors and improving the specificity of relevant statistical models. The current manuscript provides practical guidance to aid the use of these models when studying eating-related behaviors., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

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

Sedentary behavior, particularly in prolonged periods, is an important determinant of health. Little research exploring changes in sedentary behavior during behavioral weight loss programs exists. This study evaluated the magnitude of changes in total and prolonged sedentary behavior and how these changes related to changes in weight and cardiovascular outcomes during a behavioral weight loss program. Participants (n = 450) in two lifestyle modification programs underwent assessments of sedentary behavior (by accelerometry), weight, waist circumference, blood pressure, and resting heart rate at baseline and after 6 months of treatment. Sedentary behavior was defined as both total and prolonged (≥30 continuous minutes) sedentary minutes/day. Reductions in total and prolonged sedentary time were significant and were accounted for by increases in moderate-to-vigorous physical activity (MVPA). Only changes in MVPA significantly predicted change in weight when entered into a model simultaneously with changes in sedentary behavior. Changes in total and prolonged sedentary time were not associated with changes in waist circumference, heart rate, or blood pressure. Change in sedentary time was not independently associated with change in health outcomes during a behavioral weight loss treatment. High variability in changes in sedentary time indicate that individual differences may be important to examine. Reducing sedentary time may not be powerful enough to impact these health outcomes above the effects of other changes made during these programs; alternatively, it may be that increasing focus in treatment on reducing sedentary time may engender greater decreases in sedentariness, which could lead to better health outcomes.

Objective: In 2015, the Academy for Eating Disorders collaborated with international patient, advocacy, and parent organizations to craft the 'Nine Truths About Eating Disorders'. This document has been translated into over 30 languages and has been distributed globally to replace outdated and erroneous stereotypes about eating disorders with factual information. In this paper, we review the state of the science supporting the 'Nine Truths'., Methods: The literature supporting each of the 'Nine Truths' was reviewed, summarized and richly annotated., Results: Most of the 'Nine Truths' arise from well-established foundations in the scientific literature. Additional evidence is required to further substantiate some of the assertions in the document. Future investigations are needed in all areas to deepen our understanding of eating disorders, their causes and their treatments., Conclusions: The 'Nine Truths About Eating Disorders' is a guiding document to accelerate global dissemination of accurate and evidence-informed information about eating disorders.

Initial trials evaluating exposure-based interventions for eating disorders (EDs) in the 1980s demonstrated mixed results. Since that time, innovations in exposure therapy for anxiety disorders have yielded insights that can be used to refine and expand the approach to effectively target ED behaviors. This article provides a brief summary of relevant advances in exposure therapy for anxiety and outlines how these advances may be adapted and evaluated for use with ED samples. More specifically, we propose shifting to an inhibitory learning framework, considering treatment targets other than fear, and increasing variability in exposure techniques represent three important areas for future study. Overall, this article aims to provide professionals in the field with a framework for how to incorporate cutting-edge advances in exposure therapy into rigorous intervention research for EDs., (© 2017 Wiley Periodicals, Inc.)

Purpose of Review: Genetic factors contribute to the etiology of anorexia nervosa (AN). This review synthesizes the current state of knowledge about the genetic etiology of AN, provides directions for future research, and discusses clinical implications for this research., Recent Findings: Candidate gene meta-analyses indicate serotonin genes may be involved in the genetic etiology of AN. Three genome-wide association studies have been conducted and one genome-wide significant locus was identified. Cross-disorder analyses suggest shared genetic risk between AN and several psychiatric, educational, and medical phenotypes. Much has been learned about the genetic etiology of AN over the past 3 decades. However, to fully understand the genetic architecture, we must consider all aspects including common variation, cross-disorder analysis, rare variation, copy number variation, and gene-environment interplay. Findings have important implications for the development of treatment and prevention approaches and for how AN, and psychiatric and medical diseases in general, are conceptualized.

Objective: This study was designed to compare weight loss through a traditional behavioral treatment (BT) approach that integrated skills for managing the obesogenic food environment (BT + E) with an approach that integrated environmental and acceptance-based skills (BT + EA). Moderators were examined as an exploratory aim., Methods: Adults (N = 283) were randomly assigned to treatment condition and provided with 26 group-based sessions over the course of 12 months. Weight was measured in the clinic at months 0, 6, and 12., Results: Change in weight over time did not significantly differ by condition. However, race significantly moderated the effect of condition on weight loss (P = 0.04), such that African-American participants lost less weight than non-Hispanic white participants in the BT (6.2% vs. 11.5%) and BT + E conditions (6.6% vs. 12.2%), but weight loss in these two groups was similar in the BT + EA condition (9.4% vs. 11.5%). Among African Americans, rates of achieving a clinically significant weight loss (i.e., > 5%) at 12 months were higher in BT + EA (80%) than BT (57%) or BT + E (48%) (P = 0.04)., Conclusions: This innovative behavioral approach shows promise for treatment of African Americans, which is notable given the lack of progress to date addressing racial disparities in obesity intervention efficacy., (© 2017 The Obesity Society.)

Measures of dietary restraint do not consistently predict caloric restriction, and these scales appear inadequate for differentiating between healthy and risky restraint in individuals. The current study examined the relationship between self-reported dietary restraint, recent weight loss, body mass index (BMI), and eating pathology in a college sample to determine if dietary restraint coupled with caloric restriction would prove to be a more sensitive marker of eating disorder risk than restraint alone. Participants (N=245) completed a series of measures evaluating dietary restraint, recent weight loss, and eating habits. Results suggested that dietary restraint related most consistently to eating pathology, with more nuanced results for women regarding the relations between dietary restraint, recent weight loss, and BMI. Findings provided further evidence that dietary restraint and weight loss may relate to eating pathology through independent pathways. In addition, recent weight loss may be a relevant risk factor for women at lower current BMI., (Copyright © 2016 Elsevier Ltd. All rights reserved.)

Behavioural weight control programmes recommend adherence to daily energy intake goals, yet also allow for flexibility in intake across days. Evidence is lacking as to whether intake consistency is important for weight control. The current study explored the relation between day-to-day intake consistency and weight loss in the context of behavioural weight loss treatment and examined the relationship between variability in intake and several factors known to be associated with weight control success. Participants (N =  283) enrolled in a 12-month behavioural weight loss programme completed 24-h recalls of dietary intake and psychological measures. At the end of treatment, low intake variability and greater weight loss were associated, but variability was not predictive of weight loss independent of mean intake in continuous analyses. Interestingly, participants who met the programme goal of ≥10% weight loss had less intake variability compared to those who lost <10%, although groups did not differ significantly on mean intake. Results suggest that daily intake consistency may facilitate successful weight loss for some. Additionally, autonomous motivation for weight management and cognitive dietary restraint were inversely related to end-of-treatment intake variability. Additional research is needed to examine whether recommendations to limit intake variability during behavioural weight loss treatment improve long-term weight control., (© 2016 World Obesity.)

Objective: Evaluate the association between pretreatment and during-treatment weight change, as well as differences in self-regulation between those who gain weight, remain weight stable, and lose weight pretreatment., Methods: Data from the first 6 months of a behavioral weight loss study were used. Participants (n = 283) were weighed at two assessment points (screening visit and baseline) prior to the start of treatment and at every treatment session. Participants were divided into those who gained weight, remained weight stable, or lost weight between the screening visit and the first treatment session., Results: Pretreatment weight change was not significantly associated with during-treatment change. Weight change from the screening visit to month 6 was significantly different by category, with losses of 11% and 7% for those who lost and gained weight pretreatment, respectively. Weight change from first treatment session to month 6 was not different by category. Poorer self-regulation was associated with pretreatment weight gain and better self-regulation with pretreatment weight loss., Conclusions: Pretreatment weight change may not relate to success during behavioral weight loss treatment. Researchers should carefully consider when the "baseline" assessment takes place to reduce bias introduced by pretreatment weight change. Poorer self-regulation may place individuals at risk for weight gain prior to treatment., (© 2016 The Obesity Society.)

Despite common wisdom that reducing alcohol intake will facilitate weight loss, little research has examined whether participants in behavioral weight loss treatments actually decrease their alcohol intake, or whether reduced alcohol intake relates to weight loss outcomes in this context. This study examined the relationship of alcohol use to energy intake excluding alcohol and to weight in 283 overweight and obese adults participating in a 26-session behavioral weight loss treatment. The majority of participants consumed low to moderate levels of alcohol at baseline. Participants who consumed alcohol at baseline meaningfully reduced their alcohol intake by end-of-treatment. Alcohol use did not relate to weight at baseline or end-of-treatment when controlling for relevant demographic variables, and change in alcohol use was unrelated to weight change in the overall sample during treatment. However, end-of-treatment alcohol intake did relate to end-of-treatment energy intake excluding alcohol. In addition, behavioral impulsivity and change in alcohol intake interacted to predict weight loss, such that decreases in alcohol intake were associated with greater percent weight loss at end-of-treatment for participants with higher levels of impulsivity. Alcohol consumption may lead to overeating episodes, and highly impulsive individuals may be at risk for increased energy intake during or after episodes of drinking. Therefore, the recommendation to reduce alcohol intake in the context of behavioral weight loss treatment seems warranted, particularly for individuals with high levels of impulsivity., (Copyright © 2016 Elsevier Ltd.

Objectives: Eating-related disinhibition (i.e., a tendency to overeat in response to various stimuli) is associated with weight gain and poorer long-term weight loss success. Theoretically, experiential avoidance (i.e., the desire or attempts to avoid uncomfortable internal experiences), may predispose individuals to developing negative reinforcement eating expectancies (i.e., the belief that eating will help to mitigate distress), which in turn promote disinhibition. Such relationships are consistent with an acquired preparedness model, which posits that dispositions influence learning and subsequent behavior. Drawing from this framework, the current study represents the first investigation of relations between negative reinforcement eating expectancies, experiential avoidance (both general and food-specific) and disinhibited eating. In particular, the mediating role of negative reinforcement eating expectancies in the relation between experiential avoidance and disinhibited eating was examined., Method: Participants (N=107) were overweight and obese individuals presenting for behavioral weight loss treatment who completed measures of general and food-related experiential avoidance, negative reinforcement eating expectancies, and disinhibition., Results: Experiential avoidance and negative reinforcement eating expectancies significantly related to disinhibition. Furthermore, the relation between experiential avoidance and disinhibition was mediated by negative reinforcement eating expectancies., Discussion: The current study supports an acquired preparedness model for disinhibition, such that the relation between experiential avoidance and disinhibition is accounted for by expectations that eating will alleviate distress. Findings highlight the potential role of eating expectancies in models accounting for obesity risk, and identify negative reinforcement eating expectancies as a potential treatment target for reducing disinhibition., (Copyright © 2016.

Purpose: Mindful eating and intuitive eating are promoted as means to circumvent potentially maladaptive dietary restraint while maintaining a healthy weight. Although theoretically related, no studies have examined the correlations between intuitive eating, mindful eating, and restraint in the same sample. This study sought to examine these constructs and their correlations with body mass index (BMI), eating-disordered behaviors, and meal consumption in a college sample., Methods: Participants (N = 125) completed a laboratory taste-test meal and measures of each eating-related construct using the EDDS, IES, MEQ, and TFEQ-Restraint Subscale., Results: Mindful eating, intuitive eating, and restraint were not strongly correlated. Hierarchical multiple regression analyses indicated that restraint and intuitive eating accounted for significant variance in disordered eating and BMI. Elevated restraint was associated with increased BMI and disordered eating; elevated intuitive eating was associated with decreased BMI and disordered eating. Mindful eating did not correlate with any outcome variables. Follow-up analyses suggested that specific intuitive eating subscales accounted for unique variance in the relation between intuitive eating and disordered eating. Intuitive eating was the only construct that was significantly associated with meal consumption., Conclusions: Intuitive eating and restraint appear to be only weakly correlated, and each is differentially associated with meal consumption. Mindful eating does not appear to relate to outcome variables.
