Matheson BE, Gorrell S, Bohon C, Agras WS, Le Grange D, Lock J. Investigating Early Response to Treatment in a Multi-Site Study for Adolescent Bulimia Nervosa. Front Psychiatry 2020; 11:92. [PMID: 32184746 PMCID: PMC7058584 DOI: 10.3389/fpsyt.2020.00092] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Accepted: 02/04/2020] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND This secondary data analysis seeks to replicate and extend findings that early response to treatment in adolescent bulimia nervosa (BN) predicts outcome, resulting in earlier identification of patients who might need a different treatment approach. METHODS Participants were 71 adolescents (M ± SD: 15.69 ± 1.55 years; 93% female; 75% non-Hispanic) with a Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM-IV) diagnosis of BN or partial BN enrolled in a two-site treatment study. Participants were randomized to cognitive behavioral therapy for adolescents (CBT-A), family-based treatment for BN (FBT-BN), or supportive psychotherapy (SPT). The Eating Disorder Examination was administered at baseline, end-of-treatment (EOT), 6-month, and 12-month follow-up. Binge eating and purge symptoms were self-reported at each session. Outcome was defined as abstinence of binge eating and compensatory behaviors (self-induced vomiting, laxative use, diet pills, diuretics, compensatory exercise, fasting) in the 28 days prior to assessment. Receiver operating characteristic (ROC) analyses were utilized to assess the viability of predicting treatment outcomes based on reduction of symptoms within the first 10 sessions of treatment. RESULTS ROC analyses suggest that reduction in purging at session 2 (AUC =.799, p < .001) and binge eating at session 4 (AUC =.750, p < .01) were independently related to abstinence of symptoms at EOT, regardless of treatment type. Symptom reduction later in treatment predicted outcome at follow-up, as change in binge eating at session 8 and purging at session 9 were the strongest predictors of abstinence at 6-month follow-up (AUCs =.726-.763, ps < .01). Change in binge eating, but not purging behaviors, was significantly related to abstinence at 12-month follow-up (AUC =.766, p < .01). Only slight differences emerged based on treatment group, such that reductions in symptoms most predictive of abstinence at EOT occurred one session sooner in FBT-BN than SPT. CONCLUSION Reductions in binge eating and purge symptoms early in adolescent BN treatment suggest better outcome, regardless of treatment modality. Additional research with larger samples is needed to better understand which treatments, if any, contribute to earlier change in BN symptoms and/or likelihood of improved patient response.

Abstract
PURPOSE OF REVIEW The present review aims to help specialists remain up-to-date on research from the past 2 years on epidemiology, risk factors, biological correlates, treatment, and outcomes for purging disorder, a DSM-5 other specified feeding and eating disorder. RECENT FINDINGS Purging disorder affects 2.5-4.8% of adolescent females in population-based samples, but purging disorder remains relatively rare in treatment settings. Higher premorbid body mass index, body dissatisfaction, and dieting prospectively predict purging disorder onset. In studies of biological correlates, women with purging disorder demonstrated significantly greater postprandial increases in the satiety peptide, peptide tyrosine tyrosine, compared to women with bulimia nervosa and controls, and these differences predicted greater gastrointestinal distress in purging disorder. Less than half of those with purging disorder are free from an eating disorder at the end of treatment and at one or more years of follow-up, supporting the need for improved interventions. SUMMARY Purging disorder may occupy a space that falls between anorexia and bulimia nervosa, making it 'not quite' anorexia and 'not quite' bulimia and difficult to reliably distinguish from each. Improved recognition and understanding of purging disorder requires more research specifically designed to test models of risk and maintenance factors to advance interventions for those who purge without binge eating.

Abstract
OBJECTIVE This prospective study explored bidirectional associations between attachment quality towards mother, father, and peers and disordered eating among a large population-based sample of boys and girls in the transition from preadolescence to adolescence. Specifically, we examined whether insecure attachment relationships emerged as a risk factor for or as an outcome of disordered eating. METHOD A population-based sample of 904 adolescent girls and boys was assessed four times, at baseline (T1; Mage = 10.8 years) and at 2-, 4-, and 6-year follow-up (T2, T3, and T4). Prospective data were analyzed using cross-lagged panel models for each attachment figure (i.e., mother, father, peers) in a multigroup design to compare genders. RESULTS Better attachment to the mother led to less pronounced disturbed eating in girls across the entire age range and in boys across two time periods. In girls, more pronounced disordered eating at T3 predicted worse attachment to the mother at T4 and better attachment to the father at T1 predicted less disturbed eating at T2. In boys, disordered eating at T1 predicted better attachment to the father at T2. Concerning peer attachment, better attachment at T1 predicted disordered eating at T2, in boys only. No other significant cross-lagged effects emerged. DISCUSSION These findings highlight the differential and gender-specific contribution of attachment figures to the development of disordered eating in adolescence. Programs aimed at improving communication and trust in the relationship with parents might be promising in the prevention of disordered eating and the subsequent deterioration of parent-child attachment relationships.

Abstract
OBJECTIVE Emotion regulation is posited to be disrupted in eating disorders, but studies have yet to examine the linkage between eating disorder symptoms and emotion regulation strategy use in daily life. We conducted an experience sampling study investigating associations between trait-level difficulties with emotion regulation, daily emotion regulation strategy use, and eating disorder symptoms in daily life. METHOD Fifty-three undergraduate women completed a trait-level measure of difficulties with emotion regulation, then reported their use of emotion regulation strategies four times per day for seven days. At the end of each day, they also reported daily disordered eating symptoms and behaviors. RESULTS Reduced access to emotion regulation strategies at the trait-level was associated with dimensional eating disorder symptoms and food restriction across the study period. In addition, greater use of maladaptive strategies and attentional deployment and less use of adaptive strategies on a given day were associated with a higher likelihood of food restriction on that day. Moderation analyses based on baseline eating disorder symptoms indicated that associations were consistent across symptom severity. CONCLUSIONS These findings suggest that certain eating disorder symptoms are associated with difficulties in regulating emotions at the trait-level and in daily life.

Abstract
OBJECTIVE Alexithymia, or the difficulty identifying or describing one's own emotions, may be a risk factor for dysregulated eating and excess weight gain. However, the relationships between alexithymia and eating behaviors in community samples of non-clinical youth have not been well-characterized. We hypothesized that alexithymia would be positively associated with disordered and disinhibited eating in a community-based sample of boys and girls without an eating disorder. METHOD Two hundred children (8-17 years old) across the weight spectrum completed an interview to assess loss of control (LOC) eating and eating-related psychopathology, a laboratory test meal designed to induce disinhibited eating, and questionnaires to assess alexithymia, eating in the absence of hunger, and emotional eating. Linear and logistic regressions were conducted to examine the relationship between alexithymia and eating variables, with age, sex, race, and fat mass as covariates. Test meal analyses also adjusted for lean mass. Given the overlap between alexithymia and depression, all models were repeated with depressive symptoms as an additional covariate. RESULTS Alexithymia was associated with an increased likelihood of reporting LOC eating (p < .05). Moreover, alexithymia was positively associated with disordered eating attitudes, emotional eating, and eating in the absence of hunger (ps < .05). Greater alexithymia was associated with more carbohydrate and less fat intake at the test meal (ps < .05). After adjusting for depressive symptoms, alexithymia remained associated with eating in the absence of hunger and carbohydrate and fat intake (ps < .05). DISCUSSION In healthy children, alexithymia is associated with some facets of eating behavior and food intake. If supported prospectively, these preliminary findings suggest alexithymia may be a modifiable risk factor to reduce disordered eating and excess weight gain in youth.

Abstract
OBJECTIVE Binge eating is prevalent across socioeconomic status (SES) groups, but it is unclear whether risk factors for binge eating vary by SES. This study examined the prevalence of several risk factors for binge eating by SES and SES as a potential moderator of these risk factors. METHOD Participants included 2,179 individuals involved in Project EAT during early/middle adolescence (EAT-I) and 5 years later during late adolescence/emerging adulthood (EAT-II). Risk ratios were computed using modified Poisson regression of incident EAT-II binge eating on EAT-I risk factors among participants of high and low SES. Interactions between each risk factor and SES were tested. RESULTS Among higher SES adolescents, overweight/obesity (RR = 3.2; 95% CI: 1.8, 5.7), body dissatisfaction (RR = 2.6; 95% confidence intervals (CI): 1.2, 5.5), dieting (RR = 4.0; 95% CI: 2.0, 8.2), and family weight-teasing (RR = 2.3; 95% CI: 1.3, 4.3) predicted increased risk for binge eating. Among adolescents from low-SES backgrounds, overweight/obesity (RR = 1.5; 95% CI: 0.9, 2.5), dieting (RR = 2.2; 95% CI: 1.2, 3.9), and food insecurity (RR = 1.4; 95% CI: 0.7, 2.7) predicted increased risk for binge eating. Moderator analyses revealed that overweight/obesity, body dissatisfaction, dieting, and family weight-teasing were stronger risk factors in the high-SES group than the low-SES group; interactions with food insecurity could not be examined given the low prevalence of food insecurity in the high-SES group. DISCUSSION Risk factors for binge eating may vary by SES, suggesting the potential utility of modifying intervention and prevention methods based on SES. In particular, the role of food insecurity must be addressed.

Abstract
Objective: Research on the dissemination of e-mental health interventions is in an early stage, so that little is known about the reach, costs, participant characteristics, and patterns of program utilization associated with different recruitment strategies and access paths. This study investigated differences between user groups informed about an Internet-based program for the prevention and early intervention in eating disorders via different recruitment channels. Method: Participant characteristics and user behavior of 3548 participants in the Internet-based program ProYouth were analyzed. Participants were informed about ProYouth via different channels (e. g., print materials, high school, Internet). Results: Results indicate significant relationships between access paths and both user characteristics and program utilization. Participants who were informed about ProYouth at their high schools were more likely to be male, younger, and at lower risk of developing eating disorders. In contrast, other recruitment channels (e. g., Internet, print materials) resulted in participants with significantly higher risk and symptom levels who used the program more frequently and with higher intensity. Conclusion: Efforts aimed at the dissemination of Internet-based interventions should consider the effects that different recruitment channels and access paths may have on sample composition and utilization of the intervention.

Abstract
BACKGROUND Eating disorders (EDs) lead to multiple psychiatric and somatic complications and thus constitute a major public health concern. OBJECTIVES The aim of this study was to give an exhaustive view of the studies reporting the prevalence of the different EDs or total EDs and to study their evolution. METHODS A literature search following PRISMA Guidelines and limited to studies in English or French published between 2000 and 2018 was performed and relevant studies were included in this systematic review on the prevalence of EDs. The literature search revealed 94 studies with accurate ED diagnosis and 27 with broad ED diagnosis. RESULTS In 94 studies with accurate ED diagnosis, the weighted means (ranges) of lifetime ED were 8.4% (3.3-18.6%) for women and 2.2% (0.8-6.5%) for men. The weighted means (ranges) of 12-month ED prevalence were 2.2% (0.8-13.1%) for women and 0.7% (0.3-0.9%) for men. The weighted means (ranges) of point prevalence were 5.7% (0.9-13.5%) for women and 2.2% (0.2-7.3%) for men. According to continents, the weighted means (ranges) of point prevalence were 4.6% (2.0-13.5%) in America, 2.2% (0.2-13.1%) in Europe, and 3.5% (0.6-7.8%) in Asia.In addition to the former, 27 other studies reported the prevalence of EDs as broad categories resulting in weighted means (ranges) of total point prevalence of any EDs of 19.4% (6.5-36.0%) for women and 13.8% (3.6-27.1%) for men. CONCLUSIONS Despite the complexity of integrating all ED prevalence data, the most recent studies confirm that EDs are highly prevalent worldwide, especially in women. Moreover, the weighted means of point ED prevalence increased over the study period from 3.5% for the 2000-2006 period to 7.8% for the 2013-2018 period. This highlights a real challenge for public health and healthcare providers.

Abstract
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.

Abstract
In the last two decades, the number of studies focused on the mediators connecting insecure attachment with Eating Disorders (EDs), at both clinical and sub-clinical level, has considerably increased. However, there has not been a systematic synthesis of this literature to date. To fill this gap, the current meta-analytic review aimed at identifying and quantifying the extent to which mediators contribute to the explanation of this relationship. The present study was registered with PROSPERO (CRD42017076807). A comprehensive search process in seven different electronic databases retrieved 24 studies that examined how insecure attachment leads to ED symptoms through mediation analysis. Standardized regression coefficients of the indirect and total paths of 21 mediation models were pooled. Studies were coded and ranked for quality. We found evidence to show that maladaptive emotion regulation and depressive symptoms had the highest effect size for mediation (mediation ratio [PM] = 0.71). Further, body dissatisfaction, neuroticism, perfectionism, mindfulness and social comparison had significant, but moderate to low mediating effects (PM = 0.21–0.58). The methodological quality of these studies was mostly low to moderate and potential areas for development were highlighted. Our findings support the direct targeting of these psychological constructs in prevention programs and treatment of EDs. Future investigations addressing the time sequence between the variables will provide valuable clues to untangle the prospective contribution of each variable on the development and maintenance of eating pathology.

Abstract
Prospective studies have identified risk factors that predict future onset of eating disorders, but none has provided a test of the temporal sequencing of the emergence of risk factors hypothesized in a multivariate etiologic model of eating disorder development. Using data from an 8-year prospective study of 496 adolescent girls, we first conducted receiver operator characteristic plots to identify cut-points for each risk factor that optimally predicted future onset of threshold or subthreshold bulimia nervosa, binge eating disorder, and purging disorder. We then used growth curve models to estimate the age at which each participant crossed the disorder-predictive cutpoint for each risk factor, or if they did not, during follow-up, permitting a test of whether the risk factors emerged in the sequence hypothesized in the Dual Pathway etiologic model. Overall, 47% of the 51 youth who showed onset of one of these eating disorders first showed emergence of disorder-predictive levels of perceived pressure to be thin and/or thin-ideal internalization, before showing onset of disorder-predictive levels of body dissatisfaction, before showing onset of disorder-predictive levels of dieting and/or negative affect, before showing onset of the eating disorder; another 29% had one of these steps out of order or did not cross one step in this model. Youth who did not show onset of an eating disorder were significantly less likely to cross the disorder-predictive cut-points for each risk factor or to conform to the sequence of risk factor emergence hypothesized in this model. Results provide novel support for the temporal sequencing of risk factor emergence hypothesized in this multivariate etiologic model and suggest that prevention programs that reduce perceived pressure to be thin and thin-ideal internalization among early adolescent girls with these factors should reduce eating disorder onset, as well as downstream risk factors that are also aversive (e.g., body dissatisfaction and negative affect).

Abstract
PURPOSE To quantify eating disorder (ED) stability and diagnostic transition among a community-based sample of adolescents and young adult females in the United States. METHODS Using 11 prospective assessments from 9,031 U.S. females ages 9-15 years at baseline of the Growing Up Today Study, we classified cases of the following EDs involving bingeing and purging: bulimia nervosa (BN), binge ED, purging disorder (PD), and subthreshold variants defined by less frequent (monthly vs. weekly) bingeing and purging behaviors. We measured number of years symptomatic and probability of maintaining symptoms, crossing to another diagnosis, or resolving symptoms across consecutive surveys. RESULTS Study lifetime disorder prevalence was 2.1% for BN and roughly 6% each for binge ED and PD. Most cases reported symptoms during only one survey year. Twenty-six percent of cases crossed between diagnoses during follow-up. Among participants meeting full threshold diagnostic criteria, transition from BN was most prevalent, crossing most frequently from BN to PD (12.9% of BN cases). Within each disorder phenotype, 20%-40% of cases moved between subthreshold and full threshold criteria across consecutive surveys. CONCLUSIONS Diagnostic crossover is not rare among adolescent and young adult females with an ED. Transition patterns from BN to PD add support for considering these classifications in the same diagnostic category of disorders that involve purging. The prevalence of crossover between monthly and weekly symptom frequency suggests that a continuum or staging approach may increase utility of ED classification for prognostic and therapeutic intervention.

Efficacy and cost-effectiveness of Internet-based selective eating disorder prevention: study protocol for a randomized controlled trial within the ProHEAD Consortium. Trials 2019; 20:91. [PMID: 30700318 PMCID: PMC6354385 DOI: 10.1186/s13063-018-3161-y] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2018] [Accepted: 12/22/2018] [Indexed: 01/21/2023] Open
Abstract
BACKGROUND The development of efficacious, cost-effective, and widely accessible programs for the prevention of eating disorders (EDs) is crucial in order to reduce the ED-related burden of illness. Programs using dissonance-based and cognitive behavioral approaches are most effective for the selective prevention of ED. Internet-based delivery is assumed to maximize the reach and impact of preventive efforts. However, the current evidence for Internet-based ED prevention is limited. The present trial evaluates the efficacy and cost-effectiveness of two new interventions (based on dissonance theory and principles of cognitive behavioral therapy (CBT)) that are implemented as add-ons to the existing Internet-based ED prevention program ProYouth. METHODS The trial is one of five sub-projects of the German multicenter consortium ProHEAD. It is a three-arm, parallel, randomized controlled superiority trial. Participants will be randomized to (1) the online program ProYouth (active control condition) or (2) ProYouth plus a structured dissonance-based module or (3) ProYouth plus a CBT-based chat group intervention. As part of ProHEAD, a representative school-based sample of N = 15,000 students (≥ 12 years) will be screened for mental health problems. N = 309 participants at risk for ED (assessed with the Weight Concerns Scale (WCS) and the Short Evaluation of Eating Disorders (SEED)) will be included in the present trial. Online assessments will be conducted at baseline, at end of intervention (6 weeks), at 6 months follow-up, and - as part of ProHEAD - at 12 and 24 months follow-up. The primary outcome is ED-related impairment (assessed with the Child version of the Eating Disorder Examination-Questionnaire (ChEDE-Q)) at the end of the intervention. Secondary outcomes include ED-related symptomatology at follow-up, ED-related stigma, ED-related help-seeking, and acceptance of and compliance with the interventions. For the health economic evaluation data on costs of the interventions, healthcare utilization and health-related quality of life will be assessed. DISCUSSION This is the first study augmenting a flexible prevention approach such as ProYouth with structured evidence-based modules in order to overcome some of the key limitations in the current practice of ED prevention.

Abstract
Socially prescribed perfectionism appears to drive disordered eating behaviour in young women, usually via messages from fellow women. Social psychological research suggests that framing effects can be manipulated to reduce the effect of unhealthy messages. This research used contrasting messages about perfectionism to reduce perfectionism among female dieters. We recruited 147 female dieters (M age = 25.11) for a between-subjects experimental study. While completing an online questionnaire, participants were exposed to one of three sets of blog posts, which varied in content and source. These three conditions always had one anti-perfectionism message from a woman. This was presented along with either a high perfection message from a man, a high perfectionism message from a woman, or both of these messages. After reading the blog posts, women were asked to fill out a scale assessing their levels of socially prescribed perfectionism. When participants were exposed to an anti-perfectionism message from a woman, paired with a high-perfectionism message from a man, participants showed lower socially prescribed perfectionism than when both high and anti-perfectionism messages came from two women. These findings imply that strategies designed to reduce socially prescribed perfectionism may benefit from including contrasting messages, as this may shift perceived perfectionism norms. Implications for social interventions are discussed.

Abstract
This study used network analyses to test the hypotheses that desire for thinness and fear of gaining weight are related but distinct constructs that play a central role in disordered eating. Data from a sample of 251 college women were used. Sparse undirected eating disorder symptom networks were calculated. Bootstrapped difference tests for edge weights and centrality indices were used to compare the position of desire for thinness and fear of gaining weight. Desire for thinness and fear of gaining weight exhibited unique patterns of associations within the network. Desire for thinness was highly connected to body dissatisfaction, thoughts about dieting, and thoughts about binge eating. Fear of gaining weight was not. Desire for thinness emerged as the most central symptom. Our findings support the distinction between fear of gaining weight and desire for thinness and their different roles within the eating disorder symptom network.

Abstract
OBJECTIVE Previous research suggests that men with eating disorders are less likely to seek treatment than are women. Given stereotypes linked to eating disorders, men may be less likely to recognize when they have an eating disorder, which could act as a barrier to treatment-seeking. METHOD The current study examined differences in self-recognition and treatment-seeking behavior by gender, controlling for other covariates, in participants with probable DSM-5 eating disorders drawn from a larger community-based sample. RESULTS Being female and self-recognition were both associated with increased likelihood of treatment-seeking while accounting for other potential covariates, including race/ethnicity, age, BMI, and comorbid disorders. DISCUSSION Results indicate that self-recognition is a barrier to seeking treatment for both genders and does not account for help-seeking differences between women and men. Findings have implications for interventions to address barriers to treatment-seeking for eating disorders.

Abstract
INTRODUCTION Despite the high mortality and significant societal and personal costs associated with eating disorders (EDs) there are few evidence-based treatments. Part of the difficulty developing and implementing evidence-based treatments in EDs is due to the extremely high heterogeneity (e.g., variability in treatment outcome, symptom presentation etc) present. METHODS To begin to identify specific symptom heterogeneity within persons, the current study used novel within and between group and intra-individual network analyses to create longitudinal and within-person networks of ED cognitions and behaviors (N = 66 individuals diagnosed with an ED). This article provides a proof of concept study for how to use between and within-person network analyses both for the EDs and other forms of psychopathology. RESULTS We found that cognitions focused on desiring thinness played a likely maintaining role in ED pathology, across network type and across time. Furthermore, we showed that three individuals with the same diagnosis (anorexia nervosa) differed in which symptoms maintained the disorder. We use these participants to exemplify how to use intra-individual network analysis to personalize treatment focused on the primary maintaining symptoms. Finally, we found that amount of time (e.g., 4 hr vs. simultaneously) impacts how symptoms maintain each other. CONCLUSIONS These findings have implications for the development of novel personalized evidence-based treatments for EDs, as well as implications for how the field understands how psychopathology maintains itself. These data represent a first-step towards using intra-individual network analyses in the ED field, as well as for hypotheses generation in future research.

Abstract
To evaluate psychological treatments for adolescent binge-eating disorder (BED), reliable information on therapeutic process factors is needed. This study examines therapist adherence and therapeutic alliance and their associations in cognitive-behavioural therapy (CBT) for adolescents with BED. In a randomised-controlled efficacy trial, adherence and alliance were objectively determined based on 247 audio-taped CBT sessions from a sample of N = 64 adolescents with BED. Variability of adherence and alliance, explained by treatment module, patient, and therapist were examined using multilevel modeling. Although adherence and alliance were excellent and unaffected by treatment module and therapist, there was significant between-patient variability for both concepts. Adherence was negatively associated with patient's treatment expectation. Alliance was negatively associated with the number of loss of control eating episodes and positively associated with adherence. Excellent adherence supported the internal validity of CBT for adolescent BED. Associations between process factors and patient characteristics demand adequate supervision in CBT.

Abstract
Emotional and other maladaptive eating behaviors develop in response to a diversity of triggers, from psychological stress to the endless external cues in our modern food environment. While the standard approach to food- and weight-related concerns has been weight-loss through dietary restriction, these interventions have produced little long-term benefit, and may be counterproductive. A growing understanding of the behavioral and neurobiological mechanisms that underpin habit formation may explain why this approach has largely failed, and pave the way for a new generation of non-pharmacologic interventions. Here, we first review how modern food environments interact with human biology to promote reward-related eating through associative learning, i.e., operant conditioning. We also review how operant conditioning (positive and negative reinforcement) cultivates habit-based reward-related eating, and how current diet paradigms may not directly target such eating. Further, we describe how mindfulness training that targets reward-based learning may constitute an appropriate intervention to rewire the learning process around eating. We conclude with examples that illustrate how teaching patients to tap into and act on intrinsic (e.g., enjoying healthy eating, not overeating, and self-compassion) rather than extrinsic reward mechanisms (e.g., weighing oneself), is a promising new direction in improving individuals' relationship with food.

Abstract
BACKGROUND with the DSM-5 new eating disorders (EDs) diagnostic subtypes were identified within the Other Specified Feeding or Eating Disorders (OSFED) category, which have so far been under-researched. Objectives of this study were to examine differential features among OSFED subtypes, exploring short-term cognitive-behavioral therapy (CBT) response and identifying clinical predictors of therapy outcome. METHODS the sample included 176 female patients diagnosed with OSFED [82 atypical anorexia nervosa (atypical-AN), 57 purging disorder (PD), and 37 subthreshold bulimia nervosa (sub-BN)]. Assessment included eating-related, psychopathological and personality measures. RESULTS results showed similar clinical and personality profiles between the diagnostic subtypes, with hardly any differences, only observable in the core symptoms of each diagnosis. The sub-BN group was the one which showed more social impairment. Regarding treatment outcome, the three groups did not reveal significant differences in remission rates, therapeutic adherence or dropout rates, reaching rates of dropout from 36.8% to 50% (p = .391). However, different ED subtype predictors appear related with full remission or dropout risk, specifically personality traits. CONCLUSIONS our results suggest that OSFED patients may benefit similarly from the same CBT outpatient group approach. However, high dropout rates and low motivation seems to be an important limitation and challenge for future approaches.

Burnette CB, Simpson CC, Mazzeo SE. Relation of BMI and weight suppression to eating pathology in undergraduates. Eat Behav 2018; 30:16-21. [PMID: 29753283 DOI: 10.1016/j.eatbeh.2018.05.003] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2017] [Revised: 05/04/2018] [Accepted: 05/04/2018] [Indexed: 02/01/2023]
Abstract
Weight suppression (WS), the difference in one's highest and current adult weight excluding pregnancy, is associated with eating disorder (ED) symptom onset and maintenance. There is increasing evidence that WS is related to ED symptoms in non-clinical samples, but there are no known studies examining the interaction of WS and current body mass index (BMI) in this group. History of overweight is common in those with EDs, and higher weight status often delays identification and treatment. This study examined the interaction of WS and current BMI on body dissatisfaction and eating pathology in undergraduate men and women. Undergraduates (N = 476) completed online surveys assessing current height and weight, weight history, and eating attitudes and behaviors. In women (n = 333), both BMI and WS were positively associated with body dissatisfaction, restraint, and global ED symptoms. In men (n = 143), there were no significant associations with BMI, but WS was related to greater body dissatisfaction, restraint, global ED symptoms, and loss-of-control eating. Moderation analyses revealed that the effect of current BMI on shape concern (p = .005), weight concern (p = .002), global ED symptoms (p = .01), and purging behaviors (p = .04) in women and restraint (p = .03) in men weakened at the highest levels of WS. Results suggest that WS is salient in a non-clinical sample and underscore the need to evaluate both weight history and the presence of disordered eating in individuals across the BMI spectrum.

Abstract
Introduction: Eating disorder symptomatology, comprising both psychological and behavioral aspects of subclinical eating concerns, constitutes a clear precursor of developing eating disorders. It is crucial to investigate its antecedents and correlates to subsequently inform eating disorder prevention programs. The present study focused on identity formation, a core developmental task in adolescence, that has increasingly been linked to eating disorder development. Our main aim was to examine the temporal sequence between eating disorder symptomatology and identity formation. Methods: Data on eating disorder symptomatology and identity formation were collected in 530 high school students (at Time 1: mean age = 15 years; SD = 1.84; range: 12-18 years; 50.6% females) using self-report questionnaires at three annual measurement points. Cross-lagged structural equation modeling was performed to examine the directionality of effects. Results: Results indicated bidirectional effects between eating disorder symptomatology and identity formation. Identity confusion seemed to increase vulnerability to body dissatisfaction and bulimia symptoms, whereas identity synthesis seemed to protect against their development. Additionally, identity synthesis seemed to protect against the development of drive for thinness as well. At the same time, body dissatisfaction and bulimia symptoms positively predicted identity confusion and negatively predicted identity synthesis over time. Conclusion: The present study adds to the growing body of literature on identity and eating disorders by focusing on their temporal interplay in a community sample of adolescents. As bidirectional effects emerged, a greater emphasis on identity formation in eating disorder prevention programs is advocated.

Abstract
Identifying the underlying child-eating behaviours that contribute to weight differences across growth has been a constant challenge. This report reviews the various literature approaches for assessing appetite regulation. In doing so, it attempts to understand how appetite control develops and determines the eating habits in early childhood, and its effects on children’s weight status. The interaction between homeostatic and hedonic mechanisms largely explains the appetite regulation process. Homeostatic mechanisms are mediated by the biological need to maintain the body’s energy reserves, increasing the motivation to eat. On the contrary, the hedonic mechanisms are mediated by food reward, increasing the craving for high-palatable foods and triggering the release of dopamine and serotonin. There are many biological methods (plasma measurements of hormones, like leptin, ghrelin and insulin) and behavioural evaluation methods of appetite. The Children’s Eating Behaviour Questionnaire is most commonly used, due to its adequate psychometric properties tested in several population settings. The development of eating behaviours begins in utero, and several determinants may contribute to a decrease in the ability to self-regulate dietary intake. Examples include genetic predisposition, the first taste experiences and the family environment, a key determinant in this process. Several eating behaviours contribute most to childhood obesity. Among them, are the external eating (eating by external stimuli, such as the mere presence of the food or its smell), food restriction (which may potentiate the uninhibited increased intake of the restricted foods) and emotional eating (intake due to emotional variations, especially negative feelings). These eating behaviours have been linked to childhood obesity.

Abstract
Background The aim of this study was to examine the necessity of early intervention for students with potential bulimia by investigating how the eating attitudes of college students change and examining the relation between bulimic symptoms and depressive symptoms or the ability to cope with stress. Methods The study participants were students who entered Hiroshima University in 2014. This study was conducted at two time points: Time-1 in 2014 and Time-2 in 2017. The Eating Attitudes Test-26 (EAT-26), Bulimic Inventory Test, Edinburgh (BITE), Beck Depression Inventory-II (BDI-II), and Coping Inventory for Stressful Situations (CISS) were administered at Times 1 and 2, and the responses were compared between the time points. Next, we compared the BDI-II scores of the BITE improved and worsened groups. In addition, we divided the participants into a clinical group, subthreshold group, and healthy group based on the BITE score at Time-1to compared their depressive symptoms and the ability to cope with stress. Results Significantly higher BITE and BDI-II scores were recorded for both males and females at Time-2 than at Time-1. The BDI-II score at Time-1 was significantly higher in the BITE worsened group than in the BITE improved group. The BDI-II scores at Time-1 were significantly higher for both males and females in the subthreshold group than in the healthy group. Furthermore, significantly higher CISS-T and CISS-E scores were recorded at Time-1 for females in the subthreshold group than for females in the healthy group. Conclusions Based on these results, intervention for students the subthreshold group is important, and the key to intervention may be to address not only eating behaviors but also depressive symptoms and stress coping.

Abstract
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.

Abstract
The traditional view that mental disorders are distinct, categorical disorders has been challenged by evidence that disorders are highly comorbid and exist on a continuum (e.g., Caspi et al., 2014; Tackett et al., 2013). The first objective of this study was to use structural equation modeling to model the structure of psychopathology in an adolescent community-based sample (N = 2,144) including conduct disorder, attention-deficit/hyperactivity disorder (ADHD), oppositional-defiant disorder (ODD), obsessive–compulsive disorder, eating disorders, substance use, anxiety, depression, phobias, and other emotional symptoms, assessed at 16 years. The second objective was to identify common personality and cognitive correlates of psychopathology, assessed at 14 years. Results showed that psychopathology at 16 years fit 2 bifactor models equally well: (a) a bifactor model, reflecting a general psychopathology factor, as well as specific externalizing (representing mainly substance misuse and low ADHD) and internalizing factors; and (b) a bifactor model with a general psychopathology factor and 3 specific externalizing (representing mainly ADHD and ODD), substance use and internalizing factors. The general psychopathology factor was related to high disinhibition/impulsivity, low agreeableness, high neuroticism and hopelessness, high delay-discounting, poor response inhibition and low performance IQ. Substance use was specifically related to high novelty-seeking, sensation-seeking, extraversion, high verbal IQ, and risk-taking. Internalizing psychopathology was specifically related to high neuroticism, hopelessness and anxiety-sensitivity, low novelty-seeking and extraversion, and an attentional bias toward negatively valenced verbal stimuli. Findings reveal several nonspecific or transdiagnostic personality and cognitive factors that may be targeted in new interventions to potentially prevent the development of multiple psychopathologies. This study provides support for a spectrum and common liability model of psychopathology, with findings showing that in a community sample of European adolescents: a) internalizing and externalizing psychopathology share substantial variance that can be modeled as a general psychopathology factor; and (b) that the common variance across psychopathologies is associated with personality traits related to high disinhibition/impulsivity, low agreeableness, high neuroticism and hopelessness, as well as different aspect of cognitive function, namely high delay-discounting, poor response inhibition and low performance IQ.

Abstract
BACKGROUND Frontostriatal and frontoparietal abnormalities likely contribute to deficits in control and attentional processes in individuals with bulimia nervosa and to the persistence of dysregulated eating across development. This study assessed these processes and cortical thickness in a large sample of adolescent girls and women with bulimia nervosa compared with healthy controls. METHODS We collected anatomical MRI data from adolescent girls and women (ages 12-38 yr) with full or subthreshold bulimia nervosa and age-matched healthy controls who also completed the Conners Continuous Performance Test-II (CPT-II). Groups were compared on task performance and cortical thickness. Mediation analyses explored associations among cortical thickness, CPT-II variables, bulimia nervosa symptoms and age. RESULTS We included 60 girls and women with bulimia nervosa and 54 controls in the analyses. Compared with healthy participants, those with bulimia nervosa showed increased impulsivity and inattention on the CPT-II, along with reduced thickness of the right pars triangularis, right superior parietal and left dorsal posterior cingulate cortices. In the bulimia nervosa group, exploratory analyses revealed that binge eating frequency correlated inversely with cortical thickness of frontoparietal and insular regions and that reduced frontoparietal thickness mediated the association between age and increased symptom severity and inattention. Binge eating frequency also mediated the association between age and lower prefrontal cortical thickness. LIMITATIONS These findings are applicable to only girls and women with bulimia nervosa, and our cross-sectional design precludes understanding of whether cortical thickness alterations precede or result from bulimia nervosa symptoms. CONCLUSION Structural abnormalities in the frontoparietal and posterior cingulate regions comprising circuits that support control and attentional processes should be investigated as potential contributors to the maintenance of bulimia nervosa and useful targets for novel interventions.

Abstract
Binge eating disorder (BED) represents one of the most problematic clinical conditions among youths. Research has shown that the developmental stage of adolescence is a critical stage for the onset of eating disorders (EDs), with a peak prevalence of BED at the age of 16–17 years. Several studies among adults with BED have underlined that it is associated with a broad spectrum of negative consequences, including higher concern about shape and weight, difficulties in social functioning, and emotional-behavioral problems. This review aimed to examine studies focused on the prevalence of BED in the adolescent population, its impact in terms of physical, social, and psychological outcomes, and possible strategies of psychological intervention. The review of international literature was made on paper material and electronic databases ProQuest, PsycArticles, and PsycInfo, and the Scopus index were used to verify the scientific relevance of the papers. Epidemiological research that examined the prevalence of BED in adolescent samples in accordance with Diagnostic and Statistical Manual of Mental Disorders, 4th Edition showed a prevalence ranging from 1% to 4%. More recently, only a few studies have investigated the prevalence of BED, in accordance with the Diagnostic and Statistical Manual of Disorders, Fifth Edition criteria, reporting a prevalence of ~1%–5%. Studies that focused on the possible impact that BED may have on physical, psychological, and social functioning showed that adolescents with BED have an increased risk of developing various adverse consequences, including obesity, social problems, substance use, suicidality, and other psychological difficulties, especially in the internalizing area. Despite the evidence, to date, reviews on possible and effective psychological treatment for BED among young population are rare and focused primarily on adolescent females.

Abstract
PURPOSE The purposes of this study were to: 1) Describe the incidence of disordered eating, weight bias, body dissatisfaction, and psychological distress, 2) Examine the relationship between sociodemographic variables (gender, ethnicity, and income) and disordered eating, weight bias, body dissatisfaction, and psychological distress in a sample of low-income adolescents. DESIGN AND METHODS A cross-sectional study was conducted with 105 adolescents from low-income neighborhoods. Participants completed self-report questionnaires to assess eating behaviors, weight bias, body dissatisfaction, and psychological functioning. Height and weight were measured, and information on household income was collected. RESULTS The participant's mean age was 16.31 (SD=2.8) years, 66% female, 47% Hispanic, and 46% African American. The mean annual income was $17,018 (SD=11,355). Twenty-eight percent self-reported having some form of disordered eating, and 15% reported an eating disorder. The group with eating disorder reported the highest levels of weight bias (M=93.4, SD=109.6), body dissatisfaction (M=94.6, SD=47.6), and psychological distress (M=1.4, SD=0.97). CONCLUSION This study found a high prevalence of eating disorders with eating disorder participants experiencing the highest levels of weight bias and psychological distress. Future studies are needed to identify and evaluate community and school-based interventions to minimize weight bias and disordered eating. PRACTICE IMPLICATIONS Nurses are at the forefront of healthcare and should collaborate with educators, school counselors, administrators, coaches, parents, and students, to address weight bias and disordered eating in schools by implementing school-based curriculum and policies.

Abstract
PURPOSE Epidemiological data are crucial to plan adequate prevention strategies. Thus, this study aims at obtaining the prevalence of mental health problems (MHP) and subthreshold psychiatric disorders based on a representative sample of Austrian adolescents. METHODS Adolescents aged 10-18 were recruited from Austrian schools. Emotional and behavioral problems were determined using the Youth Self-Report (YSR); the point prevalence of subthreshold psychiatric disorders was assessed using structured diagnostic interviews. Sociodemographic variables including socioeconomic background, migration status, family structure, and place of residence were obtained. In addition, a non-school sample (unemployed adolescents, and child and adolescent psychiatry patients) was included to enhance representativeness and generalizability. RESULTS 3446 students, 37 unemployed adolescents, and 125 child and adolescent psychiatric patients provided analyzable YSR data sets. In the school sample, 16.5% scored in the clinically relevant range, while internalizing problems were more prevalent (17.8%) than externalizing problems (7.4%). These prevalences increased by 0.7-2.0% when the non-school sample was taken into account. A low socioeconomic status (SES) and living in single parent families were associated with higher problem scores. Regarding the interviewed sample (377 students and 407 parents), subthreshold psychiatric disorders were observed in 12.7% of students. 92.5% of them have not yet received any kind of help. CONCLUSIONS A significant proportion of Austrian adolescents are at risk for MHP. A non-responder analysis indicates that the observed prevalence may be even underestimated. These findings emphasize the urgent need for targeted prevention, especially for reducing anxiety and depressive symptoms and for adolescents in disadvantaged families.

Abstract
OBJECTIVE Little is known about biological factors that contribute to purging after normal amounts of food-the central feature of purging disorder (PD). This study comes from a series of nested studies examining ingestive behaviors in bulimic syndromes and specifically evaluated the satiety peptide YY (PYY) and the hunger peptide ghrelin in women with PD (n = 25), bulimia nervosa-purging (BNp) (n = 26), and controls (n = 26). Based on distinct subjective responses to a fixed meal in PD (Keel, Wolfe, Liddle, DeYoung, & Jimerson, ), we tested whether postprandial PYY response was significantly greater and ghrelin levels significantly lower in women with PD compared to controls and women with BNp. METHOD Participants completed structured clinical interviews, self-report questionnaires, and laboratory assessments of gut peptide and subjective responses to a fixed meal. RESULTS Women with PD demonstrated a significantly greater postprandial PYY response compared to women with BNp and controls, who did not differ significantly. PD women also endorsed significantly greater gastrointestinal distress, and PYY predicted gastrointestinal intestinal distress. Ghrelin levels were significantly greater in PD and BNp compared to controls, but did not differ significantly between eating disorders. Women with BNp endorsed significantly greater postprandial hunger, and ghrelin predicted hunger. DISCUSSION PD is associated with a unique disturbance in PYY response. Findings contribute to growing evidence of physiological distinctions between PD and BNp. Future research should examine whether these distinctions account for differences in clinical presentation as this could inform the development of specific interventions for patients with PD.

Abstract
In this study, we examined a structural equation model in which attachment anxiety and avoidance were associated with binge eating and restricted eating behaviors through distinct emotion regulation difficulties of emotional reactivity and emotional cutoff among college women ( n = 744) and men ( n = 200). As predicted, attachment anxiety was associated with emotional reactivity which, in turn, was associated with binge eating. Attachment avoidance was associated with emotional cutoff which, in turn, was associated with restricted eating, both in college women and men. Two gender differences were found: the association between emotional cutoff and binge eating was statistically significant only for women, and the association between emotional reactivity and binge eating was stronger for men than for women. Clinical implications are suggested, specifically the importance of addressing attachment insecurities and distinct emotion regulation difficulties related to serving college women and men with binge eating and/or restricted eating behaviors.

Abstract
OBJECTIVE Eating disorders (EDs) are associated with substantial morbidity and mortality, yet up to 45% of individuals with EDs never receive treatment for their eating-related problems. This study sought to identify whether comorbidity, suicidality, discrimination, family cohesion, employment status, income, sex, age, marital status, religious belongingness, and ED-specific variables (body mass index and past-year ED diagnoses) were associated with treatment seeking in a nationally representative sample of individuals with EDs (N = 595; 77.8% women; 72.4% ethnic minority). METHOD Structural equation modeling was used to identify significant predictors of treatment seeking. RESULTS In the full sample, age was associated with a greater probability of treatment seeking, and men had a lower probability of seeking treatment. No variables were significant predictors of treatment seeking among individuals in Hispanic or Caucasian subgroups. DISCUSSION To our knowledge, this was the largest study to characterize predictors of treatment seeking in adults with EDs. Results from this study were consistent with existing literature documenting age and sex differences in treatment seeking among adolescents with an ED. Findings suggest a need for improved ED education and outreach-including greater mental health/ED literacy and decreased stigmatization for patients, providers, and the general public-and additional persuasive public-health messages to change community knowledge about treatment options for younger persons and men with EDs.

Abstract
OBJECTIVE Changes in the DSM-5 eating disorders criteria sought to increase the clarity of the diagnostic categories and to decrease the preponderance of nonspecified eating disorders. The first objective of this study was to analyze how these revisions affect threshold and EDNOS/OSFED eating disorder diagnoses in terms of prevalence, sex ratios, and diagnostic distribution in a student sample. Second, we aimed to compare the impairment levels of participants with a threshold, an EDNOS/OSFED and no diagnosis using both DSM-IV and DSM-5. METHOD A sample of 1654 7th and 8th grade students completed self-report questionnaires to determine diagnoses and impairment levels in the context of an eating disorder prevention program in nine German secondary schools. Height and weight were measured. RESULTS The prevalence of threshold disorders increased from .48% (DSM-IV) to 1.15% (DSM-5). EDNOS disorders increased from 2.90 to 6.23% when using OSFED-categories. A higher proportion of girls was found throughout all the diagnostic categories, and the sex ratios remained stable. The effect sizes of DSM-5 group differences regarding impairment levels were equal to or larger than those of the DSM-IV comparisons, ranging from small to medium. DISCUSSION We provide an in-depth overview of changes resulting from the revisions of DSM eating disorder criteria in a German adolescent sample. Despite the overall increase in prevalence estimates, the results suggest that the DSM-5 criteria differentiate participants with threshold disorders and OSFED from those no diagnosis as well as or even more distinctly than the DSM-IV criteria.

Abstract
BACKGROUND Several problems with the classification and diagnosis of eating disorders (EDs) have been identified, including proliferation of 'other specified' diagnoses, within-disorder heterogeneity, and frequent diagnostic migration over time. Beyond problems within EDs, past research suggested that EDs fit better in a spectrum of internalizing psychopathology (characterized by mood and anxiety disorders) than in a separate diagnostic class. PURPOSE To develop a transdiagnostic, hierarchical-dimensional model relevant to ED psychopathology that: 1) reduces diagnostic heterogeneity, 2) includes important dimensions of internalizing psychopathology that are often excluded from ED diagnostic models, and 3) predicts clinical impairment. PROCEDURES Goldberg's (2006) method and exploratory structural equation modeling were used to identify a hierarchical model of internalizing in community-recruited adults with EDs (N=207). FINDINGS The lowest level of the hierarchy was characterized by 15 factors that defined specific aspects of eating, mood, and anxiety disorders. At the two-factor level, Internalizing bifurcated into Distress (low well-being, body dissatisfaction, suicidality, dysphoria, ill temper, traumatic intrusions) and Fear-Avoidance (claustrophobia, social avoidance, panic symptoms, dietary restricting, excessive exercise, and compulsions). Results showed that the lowest level of the hierarchy predicted 67.7% of the variance in clinical impairment. In contrast, DSM eating, mood, and anxiety disorders combined predicted 10.6% of the variance in impairment secondary to an ED. CONCLUSIONS The current classification model represents an improvement over traditional nosologies for predicting clinically relevant outcomes for EDs.

An experimental therapeutics test of whether adding dissonance-induction activities improves the effectiveness of a selective obesity and eating disorder prevention program.

Abstract
OBJECTIVE Compare the Healthy Weight obesity and eating disorder prevention program, which promotes participant-driven gradual lifestyle changes to bring energy intake and expenditure into balance, to a new intervention, Project Health, which adds activities to create cognitive dissonance about unhealthy eating, a sedentary lifestyle, and excess body fat, and an obesity education video-control condition. METHOD College students at risk for both outcomes because of weight concerns (N=364, 72% female) were randomized to condition, completing pretest, posttest, and 6, 12 and 24-month follow-up assessments. RESULTS Project Health participants showed significantly smaller increases in measured body mass index (BMI) through 2-year follow-up than both Healthy Weight participants and controls (both d=-0.18), and significantly lower onset of overweight/obesity over 2-year follow-up than Healthy Weight participants and controls (13 vs 21% and 22%). Healthy Weight and Project Health participants showed significantly greater eating disorder symptom reductions than controls through 2-year follow-up. Healthy Weight and Project Health participants showed marginally lower eating disorder onset over follow-up than controls (3 and 3% vs 8% respectively). CONCLUSIONS The reduced increases in BMI and future overweight/obesity onset for Project Health relative to both an active matched intervention and a minimal intervention control condition are noteworthy, especially given the short 6-h intervention duration. The reduction in eating disorder symptoms for Healthy Weight and Project Health relative to controls was also encouraging. Results suggest that adding dissonance-induction activities increased weight loss effects. Yet, effects for both were generally small and the eating disorder onset prevention effects were only marginal, potentially because intervention groups included both sexes, which reduced eating disorder incidence and sensitivity.

Abstract
Objective: To estimate the prevalence of disordered eating behaviors (DEB) and identify their associations with demographic and psychological variables among freshman students at a public university in Mexico City. Materials and methods: A sample of 892 subjects participated in the study. Bivariate and multinomial models were performed to determine associations between DEB and covariates. Results: Of those surveyed, 6.8% of the women and 4.1% of the men exhibited DEB (p<0.05). The variables increasing the risk of eating disorders (ED) for women were internalization of the aesthetic thin ideal (IATI), body mass index (BMI), self-esteem and physical activity, while for men they were IATI, drive for muscularity, and self-esteem. Conclusions: The frequency of DEB among women and men and the internalization of the thin ideal in both sexes suggest the possibility of a change in the precursor conditions for eating disorders, particularly for men, who exhibit increased risk of such behaviors.

Abstract
BACKGROUND The aims of this study were to analyse the quality of life (QoL) of a broad sample of patients with eating disorders (ED) and to identify potential factors that predict QoL. METHODS This prospective cohort study involved 528 patients diagnosed with ED and treated over a 15-year period in the Eating Disorders Outpatient Clinic. Information on sociodemographic and clinical data were gathered. Patients completed five self-administered instruments: the Eating Attitudes Test-26 (EAT-26); the Eating Disorder Diagnostic Scale (EDDS); the Hospital Anxiety and Depression Scale (HADS); the Short-Form 12 (SF-12); and the Quality of Life in ED-short form (HeRQoLED-s). Descriptive, univariate analyses and multivariate linear regression models were applied to identify factors associated with QoL. RESULTS Predictive variables for a low level of QoL in patients with anorexia nervosa (AN) included antidepressant treatment (P=0.009), substance abuse disorder, (P=0.03) and other organic comorbidities (P<0.0001). For patients with bulimia nervosa (BN), they included osteoporosis (P≤0.0001), obesity (P=0.0004) or being a student (P=0.04). For patients with eating disorders not otherwise specified (EDNOS), they included anxiolytic treatment (P=0.003), having circulatory disease (P=0.001), more years since start of ED treatment (P=0.03) and living alone (P<0.0001). CONCLUSIONS We found a significant difference in QoL between the diagnostic ED groups. With regard to the variables predicting QoL in ED patients, the findings of this study suggest that organic or psychiatric comorbidities and some data of social normality might be more relevant to QoL in ED than age, type of compensatory behaviour, BMI or number of visits to hospital emergency department.

Abstract
Eating disorders are serious illnesses associated with significant morbidity and mortality. Family-based treatment (FBT) has emerged as an effective intervention for adolescents with anorexia nervosa, and preliminary evidence suggests that it may be efficacious in the treatment of adolescents with bulimia nervosa. Multifamily therapy for anorexia nervosa provides a more intensive experience for families needing additional support. This review outlines the three phases of treatment, key tenets of family-based treatment, and empirical support for FBT. In addition, FBT in higher levels of care is described, as well as challenges in the implementation of FBT and recent adaptations to FBT, including offering additional support to eating-disorder caregivers. Future research is needed to identify families for whom FBT does not work, determine adaptations to FBT that may increase its efficacy, develop ways to improve treatment adherence among clinicians, and find ways to support caregivers better during treatment.

Abstract
Using data from an effectiveness trial delivered by college clinicians, we examined the cost-effectiveness of the dissonance-based Body Project program for reducing eating disorder symptoms in women with body dissatisfaction. The outcome of interest was individual-level change; 14.9% of Body Project participants attained clinically meaningful improvement vs. 6.7% of controls. Delivering the intervention costs approximately $70 (2012 U.S. dollars) per person. Incremental cost-effectiveness was $838 for each additional at-risk person reducing eating disorder symptomology to a clinically meaningful degree. These analyses demonstrate the economic value of the Body Project for college-age women with symptoms below the eating disorder diagnosis threshold.

Abstract
Food addiction is controversial within the scientific community. However many lay people consider themselves addicted to certain foods. We assessed the prevalence and characteristics of self-perceived "food addiction" and its relationship to a diagnostic measure of "clinical food addiction" in two samples: (1) 658 university students, and (2) 614 adults from an international online crowdsourcing platform. Participants indicated whether they considered themselves to be addicted to food, and then completed the Yale Food Addiction Scale, measures of eating behavior, body image, and explicit and internalized weight stigma. Participants in the community sample additionally completed measures of impulsivity, food cravings, binge eating, and depressive symptomatology. Follow-up data were collected from a subset of 305 students (mean follow-up 280 ± 30 days). Self-perceived "food addiction" was prevalent, and was associated with elevated levels of problematic eating behavior, body image concerns, and psychopathology compared with "non-addicts", although individuals who also received a positive "diagnosis" on the Yale Food Addiction Scale experienced the most severe symptoms. A clear continuum was evident for all measures despite no differences in body mass index between the three groups. Multinomial logistic regression analyses indicated that perceived lack of self-control around food was the main factor distinguishing between those who did and did not consider themselves addicted to food, whereas severity of food cravings and depressive symptoms were the main discriminating variables between self-classifiers and those receiving a positive "diagnosis" on the Yale Food Addiction Scale. Self-perceived "food addiction" was moderately stable across time, but did not appear predictive of worsening eating pathology. Self-classification as a "food addict" may be of use in identifying individuals in need of assistance with food misuse, loss-of-control eating, and body image issues.

Abstract
PURPOSE Given shared risk and maintaining factors between eating disorders and obesity, it may be important to include both eating disorder intervention and healthy weight management within a universal eating disorder care delivery program. This study evaluated differential eating disorder screening responses by initial weight status among university students, to assess eating disorder risk and pathology among individuals with overweight/obesity versus normal weight or underweight. METHODS 1529 individuals were screened and analyzed. Screening was conducted via pilot implementation of the Internet-based Healthy Body Image program on two university campuses. RESULTS Fifteen percent of the sample had overweight/obesity. Over half (58%) of individuals with overweight/obesity screened as high risk for an eating disorder or warranting clinical referral, and 58% of individuals with overweight/obesity endorsed a ≥10-pound weight change over the past year. Compared to individuals with normal weight or underweight, individuals with overweight/obesity were more likely to identify as Black, endorse objective binge eating and fasting, endorse that eating disorder-related concerns impaired their relationships/social life and made them feel badly, and endorse higher weight/shape concerns. CONCLUSIONS Results suggest rates of eating disorder pathology and clinical impairment are highest among students with overweight/obesity, and targeted intervention across weight categories and diverse races/ethnicities is warranted within universal eating disorder intervention efforts. Integrating eating disorder intervention and healthy weight management into universal prevention programs could reduce the incidence and prevalence of eating disorders, unhealthy weight control practices, and obesity among university students.

Abstract
The prevention of eating disorders and the identification of high-risk individuals are essential for the public health sector. There is need for sensitive and specific screening instruments of disordered eating that can be applied in universal samples as an initial step into disease prevention. The SCOFF is a screening instrument for disordered eating, frequently used in international and cross-cultural contexts to detect individuals at risk. The objective of this research is to evaluate whether the SCOFF can be used as a screening tool for disordered eating in universal samples. This is the first study which examined the psychometric properties of the German version of the SCOFF in a general population sample. A representative sample (N=2527) of the German population, aged 14-95years, was recruited. Psychometric properties were determined including reliability, concurrent and construct validity, and factor structure. The prevalence of disordered eating was assessed. The prevalence of disordered eating in the general population was 10%. Using the established cutoff point of ≥2, values for diagnostic accuracy were 26% (sensitivity), 97% (specificity), 80% (positive predictive value), and 74% (negative predictive value). Factorial analyses revealed an excellent model fit of a unidimensional model. Due to its low sensitivity and a high percentage of false negatives, there are limitations in using the German version of the SCOFF in general population samples with wide age ranges.

Thompson A, Petrie T, Anderson C. Eating disorders and weight control behaviors change over a collegiate sport season. J Sci Med Sport 2017; 20:808-813. [PMID: 28416353 DOI: 10.1016/j.jsams.2017.03.005] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2016] [Revised: 02/13/2017] [Accepted: 03/13/2017] [Indexed: 11/28/2022]
Abstract
OBJECTIVES Determine whether the prevalence of eating disorder classifications (i.e., clinical eating disorder, subclinical eating disorder, and asymptomatic) and pathogenic weight control behaviors (e.g., bingeing, vomiting) change over a five-month sport season. DESIGN Longitudinal study. METHODS Female collegiate gymnasts and swimmers (N=325) completed the Questionnaire for Eating Disorder Diagnoses as well as six items from the Bulimia Test-Revised at Time 1 (two weeks into the beginning of their athletic season) and Time 2 (final two weeks of the athletic season); data collections were separated by five months. RESULTS Over the course of the season, 90% of the athletes (18 out of 20) retained a clinical eating disorder diagnosis or moved to the subclinical classification. Of the 83 subclinical athletes at Time 1, 37.3% persisted with that classification and 10.8% developed a clinical eating disorder; the remainder became asymptomatic/healthy eaters by Time 2. The majority of Time 1 asymptomatic athletes (92.3%) remained so at Time 2. Exercise and dieting/fasting were the most frequent forms of weight control behaviors, though each was used less frequently at Time 2 (exercise=35.4%; dieting=9.2%) than at Time 1 (exercise=42.5%; dieting=12.3%). CONCLUSIONS Eating disorder classifications, particularly clinical and subclinical, remain stable across a competitive season, supporting the need for early detection and purposeful intervention. Athletes engage in weight control behaviors that may be reinforced in the sport environment (e.g., supplemental exercise), making identification more challenging for sports medicine professionals.

[PMID: 28214633 DOI: 10.1016/j.cpr.2017.02.001] [Citation(s) in RCA: 146] [Impact Index Per Article: 20.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2016] [Revised: 02/09/2017] [Accepted: 02/10/2017] [Indexed: 01/02/2023]
Abstract
OBJECTIVE To systematically review and quantify the effectiveness of Eating Disorder (ED) prevention interventions. METHODS Electronic databases (including the Cochrane Controlled Trial Register, MEDLINE, PsychInfo, EMBASE, and Scopus) were searched for published randomized controlled trials of ED prevention interventions from 2009 to 2015. Trials prior to 2009 were retrieved from prior reviews. RESULTS One hundred and twelve articles were included. Fifty-eight percent of trials had high risk of bias. Findings indicated small to moderate effect sizes on reduction of ED risk factors or symptoms which occurred up to three-year post-intervention. For universal prevention, media literacy (ML) interventions significantly reduced shape and weight concerns for both females (-0.69, confidence interval (CI): -1.17 to -0.22) and males (-0.32, 95% CI -0.57 to -0.07). For selective prevention, cognitive dissonance (CD) interventions were superior to control interventions in reducing ED symptoms (-0.32, 95% CI -0.52 to -0.13). Cognitive behavioural therapy (CBT) interventions had the largest effect size (-0.40, 95% CI -0.55 to -0.26) on dieting outcome at 9-month follow-up while the healthy weight intervention reduced ED risk factors and body mass index. No indicated prevention interventions were found to be effective in reducing ED risk factors. CONCLUSIONS There are a number of promising preventive interventions for ED risk factors including CD, CBT and ML. Whether these actually lower ED incidence is, however, uncertain. Combined ED and obesity prevention interventions require further research.
