Velkoff EA, Rubino LG, Liu J, Manasse SM, Juarascio AS. Early reduction in anxiety sensitivity predicts greater reduction in disordered eating and trait anxiety during treatment for bulimia nervosa. Int J Eat Disord 2024; 57:1791-1796. [PMID: 38578224 PMCID: PMC11343650 DOI: 10.1002/eat.24207] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 03/22/2024] [Accepted: 03/22/2024] [Indexed: 04/06/2024]
Abstract
OBJECTIVE Anxiety sensitivity (AS), the trait-like fear of symptoms of anxiety, has been associated with eating disorder (ED) pathology broadly, bulimia nervosa (BN) symptoms specifically, and the anxiety disorders that are commonly comorbid with BN. AS, especially for physical symptoms specifically, maybe a risk and maintenance factor for BN and comorbid anxiety. METHOD Adult participants with BN (n = 44) in a clinical trial comparing CBT to mindfulness and acceptance-based treatment (MABT) reported ED symptoms, trait anxiety, and AS through treatment and follow-up. We predicted that greater early reduction (i.e., within the first month of treatment) in AS would predict greater reductions in ED symptoms and trait anxiety at post-treatment and follow-up. RESULTS Early reductions in AS for physical concerns predicted lower ED symptoms and trait anxiety at post-treatment but not follow-up. Exploratory analyses indicated that treatment groups did not differ in either early or total change in AS, controlling for baseline AS. DISCUSSION Early reductions in AS may be an important treatment target for BN, and may additionally support reductions in anxiety. Future research should identify which components of CBT and MABT best target AS, to deliver these components early in treatment, when they can have maximum effect. PUBLIC SIGNIFICANCE Anxiety sensitivity, the fear of symptoms of anxiety, is associated with eating disorders (ED). In this study, participants in treatment for bulimia nervosa reported ED symptoms, trait anxiety, and anxiety sensitivity through treatment and follow-up. Greater early reductions in anxiety sensitivity predicted lower ED symptoms and trait anxiety at post-treatment. Future research should identify which elements of treatment best target anxiety sensitivity, to deliver them early in treatment.

The Impact of High Levels of Compensatory Exercise on Treatment Outcomes in Threshold and Subthreshold Bulimia Nervosa. Nutrients 2024; 16:2337. [PMID: 39064779 PMCID: PMC11279786 DOI: 10.3390/nu16142337] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2024] [Revised: 07/18/2024] [Accepted: 07/18/2024] [Indexed: 07/28/2024] Open
Abstract
Bulimia nervosa (BN) and other specific feeding or eating disorders with subthreshold BN symptoms (OSFED-BN) are characterized by recurrent binge eating episodes accompanied by compensatory behaviors, including excessive exercise. We aimed to examine the role of compensatory exercise on several clinical disorder-related variables and the treatment outcomes. The sample included 478 patients diagnosed with either BN or OSFED-BN admitted for a 16-week eating disorder-specific treatment program. A battery of questionnaires was administered to evaluate eating and general psychopathology, and personality traits. Other clinical disorder-related data, including levels of compensatory exercise, were assessed through a semi-structured clinical interview. Between-group comparisons of compensatory exercise levels were analyzed, as a predictive model of risk of poor treatment outcomes. Path analysis was conducted using structural equation models to estimate the direct and indirect effects between the main variables. Higher levels of self-reported compensatory exercise were associated with greater eating psychopathology, general psychopathology, and more dysfunctional personality traits and were a predictor of poor treatment outcomes. Additionally, these levels achieved a mediating role in several paths contributing to a higher likelihood of a poor outcome. Further research is required to determine how psychotherapeutic approaches can be optimized to adequately include adaptive exercise for these patients.

Abstract
OBJECTIVE There are limited data to guide the interpretation of scores on measures of eating-disorder psychopathology among underrepresented individuals. We aimed to provide norms for the Eating Disorder Examination-Questionnaire (EDE-Q) and Clinical Impairment Assessment (CIA) across racial/ethnic, gender, and sexual identities, and sexual orientations and their intersections by recruiting a diverse sample of Amazon MTurk workers (MTurkers; N = 1782). METHOD We created a comprehensive, quantitative assessment of racial/ethnic identification, gender identification, sex assigned at birth, current sexual identification, and sexual orientation called the Demographic Assessment of Racial, Sexual, and Gender Identities (DARSGI). We calculated normative data for each demographic category response option. RESULTS Our sample was comprised of 68% underrepresented racial/ethnic identities, 42% underrepresented gender identities, 13% underrepresented sexes, and 49% underrepresented sexual orientations. We reported means and standard deviations for each demographic category response option and, where possible, mean estimates by percentile across intersectional groups. EDE-Q Global Score for a subset of identities and intersections in the current study were higher than previously reported norms for those identities/intersections. DISCUSSION This is the most thorough reporting of norms for the EDE-Q and CIA among racial/ethnic, sexual, and gender identities, and sexual orientations and the first reporting on multiple intersections, filling some of the gaps for commonly used measures of eating-disorder psychopathology. These norms may be used to contextualize eating-disorder psychopathology reported by underrepresented individuals. The data from the current study may help inform research on the prevention and treatment of eating-disorder psychopathology in underrepresented groups. PUBLIC SIGNIFICANCE We provide the most thorough reporting on racial/ethnic, sexual, and gender identities, and sexual orientations for the Eating Disorder Examination - Questionnaire and Clinical Impairment Assessment, and the first reporting on intersections, which fills some of the gaps for commonly used measures of eating-disorder psychopathology. These norms help inform research on the prevention and treatment of eating-disorder psychopathology in underrepresented groups.

Kenny TE, Trottier K, Lewis SP. Lived experience perspectives on a definition of eating disorder recovery in a sample of predominantly white women: a mixed method study. J Eat Disord 2022; 10:149. [PMID: 36224653 PMCID: PMC9558402 DOI: 10.1186/s40337-022-00670-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2022] [Accepted: 08/24/2022] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND There has recently been a push for recovery-focused research in the eating disorder (ED) field, starting with a consensus definition of recovery. One definition, in particular, proposed by Bardone-Cone et al. [21] has received considerable attention given its transdiagnostic nature and validation studies. However, no studies to date have elicited lived experience views of this definition. The goal of the current study was to examine perspectives on this definition of recovery from individuals with a past or present ED and to determine whether participant agreement with the model differed based on diagnostic history or current symptom severity. METHODS Sixty-two individuals (95.2% women; 91.9% White/European) participated in a 1-2 h interview aimed at capturing their perspectives on ED recovery. Transcripts were analyzed using qualitative content analysis and codebook thematic analysis to examine agreement with and thoughts on Bardone-Cone's definition of recovery, respectively. Chi-squared tests of independence and binary logistic regression were computed to determine whether agreement with the definition differed across diagnostic history and self-reported symptoms. RESULTS Although some participants indicated acceptance of the definition, the majority expressed concerns related to its categorical nature, proposed criteria, feasibility, language, and applications. There were no differences in acceptance based on diagnostic history or current symptom severity. CONCLUSION A single definition of recovery does not seem to fit individuals' lived ED experience. Future research may benefit from distinguishing between recovery as an individually-defined phenomenon and related constructs such as remission (i.e., loss of diagnosis or absence of clinical symptoms). A more comprehensive multi-faceted, and person-centered model of recovery may have merit in clinical settings.

Abstract
About 20% of individuals with anorexia nervosa (AN) remain chronically ill. Therefore, early identification of poor outcome could improve care. Genetic research has identified regions of the genome associated with AN. Patients with anorexia nervosa were identified via the Swedish eating disorder quality registers Stepwise and Riksät and invited to participate in the Anorexia Nervosa Genetics Initiative. First, we associated genetic information longitudinally with eating disorder severity indexed by scores on the Clinical Impairment Assessment (CIA) in 2843 patients with lifetime AN with or without diagnostic migration to other forms of eating disorders followed for up to 16 years (mean = 5.3 years). Second, we indexed the development of a severe and enduring eating disorder (SEED) by a high CIA score plus a follow-up time ≥5 years. We associated individual polygenic scores (PGSs) indexing polygenic liability for AN, schizophrenia, and body mass index (BMI) with severity and SEED. After multiple testing correction, only the BMI PGS when calculated with traditional clumping and p value thresholding was robustly associated with disorder severity (βPGS = 1.30; 95% CI: 0.72, 1.88; p = 1.2 × 10-5) across all p value thresholds at which we generated the PGS. However, using the alternative PGS calculation method PRS-CS yielded inconsistent results for all PGS. The positive association stands in contrast to the negative genetic correlation between BMI and AN. Larger discovery GWASs to calculate PGS will increase power, and it is essential to increase sample sizes of the AN GWASs to generate clinically meaningful PGS as adjunct risk prediction variables. Nevertheless, this study provides the first evidence of potential clinical utility of PGSs for eating disorders.

A Danish nationwide register-based cohort study. Addiction 2022; 117:354-367. [PMID: 34251067 DOI: 10.1111/add.15639] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2020] [Revised: 12/01/2020] [Accepted: 06/30/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND AND AIM No large-scale, longitudinal clinical study has examined whether patients with different types of eating disorders (ED) have an increased risk of a subsequent alcohol use disorder (AUD). This study aimed to assess the ongoing risk of receiving a diagnosis of AUD following a first-time diagnosis of anorexia nervosa (AN), bulimia nervosa (BN), or unspecified ED (USED). DESIGN Retrospective cohort study. SETTING Danish nationwide registries, January 1994 to December 2018. PARTICIPANTS A total of 20 759 ED patients and 83 036 controls were followed from the date of first ED diagnosis (index date) until the date of first AUD diagnosis, death, emigration, or the end of the study. Controls were selected in a 1:4 ratio and matched on month and year of birth, gender and ethnicity. MEASUREMENTS We obtained data on ED (AN, BN, USED; exposure) and AUD (abuse/dependence; outcome) diagnoses as well as sociodemographics and other psychiatric diagnoses. Time to AUD was generated from the index date. Risk of AUD after the index date was assessed among those without a prior AUD diagnosis while adjusting for sociodemographics and prior psychiatric diagnoses. FINDINGS Compared with controls, an increased relative risk of AUD after the index date was observed in AN patients throughout the study lasting 15 + years (adjusted hazard ratios [HRs] ranging from 2.49 [99% CI = 1.46, 4.25] to 6.83 [2.84, 16.41]), in BN patients during the first year of follow-up and from 2 years onward (2.72 [1.66, 4.44] to 17.44 [6.01, 50.63]), and in USED patients during the first year and 2-15 years of follow-up (2.52 [1.54, 4.14] to 14.17 [5.86, 34.27]). In all three groups, estimates were highest during the first year, particularly among BN patients. CONCLUSIONS Patients with anorexia nervosa, bulimia nervosa, or unspecified eating disorders appear to have an increased ongoing risk of receiving a diagnosis of alcohol use disorder following their first eating disorder diagnosis compared with controls.

Temperament-based treatment for young adults with eating disorders: acceptability and initial efficacy of an intensive, multi-family, parent-involved treatment. J Eat Disord 2021; 9:110. [PMID: 34496951 PMCID: PMC8424819 DOI: 10.1186/s40337-021-00465-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2021] [Accepted: 08/23/2021] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND Adult eating disorder treatments are hampered by lack of access and limited efficacy. This open-trial study evaluated the acceptability and preliminary efficacy of a novel intervention for adults with eating disorders delivered to young adults and parent-supports in an intensive, multi-family format (Young Adult Temperament-Based Treatment with Supports; YA-TBT-S). METHODS 38 YA-TBT-S participants (m age = 19.58; SD 2.13) with anorexia nervosa (AN)-spectrum disorders, bulimia nervosa (BN)-spectrum disorders, and avoidant/restrictive food intake disorder (ARFID) completed self-report assessments at admission, discharge, and 12-month follow-up. Assessments measured program satisfaction, eating disorder psychopathology and impairment, body mass index (BMI), and trait anxiety. Outcomes were analyzed using linear mixed effects models to examine changes in outcome variables over time. RESULTS Treatment was rated as highly satisfactory. 53.33% were in partial or full remission at 12-month follow-up. 56% of participants received other treatment within the 12-month follow-up period, suggesting that YA-TBT-S may be an adjunctive treatment. Participants reported reductions in ED symptomatology (AN and BN), increases in BMI (AN and ARFID), and reductions in clinical impairment (AN and ARFID) at 12-month follow-up. CONCLUSIONS YA-TBT-S is a feasible and acceptable adjunctive treatment for young adults with a broad range of ED diagnoses and may be a method for involving parents in ED treatment in ways that are acceptable to both parents and YA. Further evaluation of efficacy is needed in larger samples, and to compare YA-TBT-S to other ED treatment approaches. Plain English summary Eating disorders are costly and dangerous psychiatric disorders that affect millions of individuals each year. Despite their risks and societal costs, currently available treatments are limited. This study examined the acceptability and efficacy of Young Adult, Temperament-Based Treatment with Supports (YA-TBT-S), a new treatment program for adults with eating disorders. YA-TBT-S was rated highly, and a significant portion of participants improved based on ratings collected 12 months after program participation. Those with anorexia nervosa (AN) and bulimia nervosa (BN) showed significant reductions in eating disorder pathology, and those with AN and avoidant/restrictive food intake disorder (ARFID) showed increases in BMI over time.

Canadian Journal of Public Health 2021; 112:919-926. [PMID: 34076877 DOI: 10.17269/s41997-021-00526-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/07/2020] [Accepted: 03/31/2021] [Indexed: 11/17/2022]
Abstract
OBJECTIVE This study investigated the rates of and change in past-year antidepressant use from 1999 to 2017 among a representative sample of Ontario adults and past-year alcohol users and problem drinkers. It examined whether alcohol use and problem drinking are associated with antidepressant use over time, whether gender moderated the effect of problem drinking on antidepressant use, and the potential correlates of past-year antidepressant use. METHOD This study utilized data from the Centre for Addiction and Mental Health Monitor study, a repeat cross-sectional telephone survey of the Ontario general adult population. Data are from 15 annual cycles of the survey 1999-2017 (where relevant variables were included), resulting in a sample size of N = 35,210. Variables of interest included demographic variables, past-year antidepressant use, past-year alcohol use, and past-year problem drinking (e.g., 8+ on the Alcohol Use Disorders Identification Test). RESULTS Past-year antidepressant use increased from 1999 to 2017 similarly among the full sample, past-year alcohol users, and past-year problem drinkers. Approximately 9% of Ontarians reported past-year antidepressant use in 2017. Overall, past-year problem drinkers were 1.5 times more likely to use antidepressants than non-problem drinkers. Past-year alcohol use was not associated with antidepressant use. Gender moderated the association between past-year problem drinking and antidepressant use. CONCLUSION This study determined that past-year antidepressant use increased from 1999 to 2017, that past-year problem drinkers are more likely to use antidepressants than non-problem drinkers, and that past-year problem drinking is associated with past-year antidepressant use among women but not among men.

Neurobiological and Psychological Maintenance Mechanisms Associated with Anticipatory Reward in Bulimia Nervosa. ACTA ACUST UNITED AC 2021; 6.

Abstract
The purpose of this investigation is to identify the anticipatory reward mechanisms that maintain binge eating and purging in bulimia nervosa. Emerging data indicate the importance of reward and anticipatory processes as maintenance mechanisms of bulimia nervosa that can be targeted in treatment. The proposed research will identify neurobiological and psychological anticipatory mechanisms of binge eating and purging using functional magnetic resonance imaging (fMRI), and ecological momentary assessment (EMA) in the natural environment. In this investigation, 60 adults (30 with bulimia nervosa and 30 matched comparison participants) will undergo negative and positive mood inductions followed by an fMRI food selection task (and a comparison shopping task) to examine neurobiological and affective responses to food and non-food reward anticipation. Participants with bulimia nervosa will complete two weeks of EMA examining real-time affect changes in relation to the anticipation of binge eating and purging. These methods will facilitate rigorous assessment of the links between neurobiological (fMRI) and naturalistic (EMA) data in anticipatory reward processes. Findings from this investigation will inform the conceptualization and treatment of bulimia nervosa by identifying the role of reward anticipation in symptom maintenance, providing a crucial framework for targeting these anticipatory processes in existing and novel interventions.

Abstract
OBJECTIVE To assess the ability of psychotherapists to predict the future outcome for inpatients with anorexia nervosa (AN) and bulimia nervosa (BN). METHOD Psychotherapists rated the prognosis of the patient's eating disorder on a five point Likert scale on several dimensions at the end of inpatient treatment. Actual outcome was assessed about 10 years after treatment. The sample comprised 1,065 patients treated for AN, and 1,192 patients treated for BN. RESULTS Psychotherapists' rating of their patient's prognosis was not better than chance for good outcome in AN and BN and for poor outcome in BN. Prediction of poor outcome in AN was somewhat better with approximately two thirds of correct predictions. In logistic regression analysis, psychotherapists' rating of the patients' prognosis for AN contributed to the explained variance of long-term outcome, increasing the variance explained from 7% (by conventional predictors) to 8% after including psychotherapists' prognosis. In BN, there was no significant contribution of psychotherapists' prognosis to overall prediction. DISCUSSION Our current knowledge of risk and protective factors for the course of eating disorders is unsatisfying. More specialized research is urgently needed.

Abstract
BACKGROUND The DSM-5 introduced purging disorder (PD) as an other specified feeding or eating disorder characterized by recurrent purging in the absence of binge eating. The current study sought to describe the long-term outcome of PD and to examine predictors of outcome. METHODS Women (N = 84) who met research criteria for PD completed a comprehensive battery of baseline interview and questionnaire assessments. At an average of 10.24 (3.81) years follow-up, available records indicated all women were living, and over 95% were successfully located (n = 80) while over two-thirds (n = 58) completed follow-up assessments. Eating disorder status, full recovery status, and level of eating pathology were examined as outcomes. Severity and comorbidity indicators were tested as predictors of outcome. RESULTS Although women experienced a clinically significant reduction in global eating pathology, 58% continued to meet criteria for a DSM-5 eating disorder at follow-up. Only 30% met established criteria for a full recovery. Women reported significant decreases in purging frequency, weight and shape concerns, and cognitive restraint, but did not report significant decreases in depressive and anxiety symptoms. Quality of life was impaired in the physical, psychological, and social domains. More severe weight and shape concerns at baseline predicted meeting criteria for an eating disorder at follow-up. Other baseline severity indicators and comorbidity did not predict the outcome. CONCLUSIONS Results highlight the severity and chronicity of PD as a clinically significant eating disorder. Future work should examine maintenance factors to better adapt treatments for PD.

Abstract
OBJECTIVE This systematic review and meta-analysis examine the contribution of duration to treatment outcome for eating disorders. METHOD Studies (n = 31) were identified that examined associations (r) between duration and 45 different outcomes. We were unable to extract r for seven studies (9 outcomes) and extracted r for 36 outcomes across 24 studies (2,349 participants). Indicators of treatment outcome were heterogeneous and thus a series of different meta-analyses, aimed at increasing homogeneity, were conducted. RESULTS First, we examined the average effect size for one primary eating disorder related outcome from each of the 24 studies. There was no association between duration and treatment outcome (r = .05, 95% CI: -.03:.13), with high heterogeneity. Second, we conducted three sub-group analyses to explore possible sources of heterogeneity (diagnosis: anorexia nervosa versus bulimia nervosa; nature of the outcome: binary versus continuous; or type of outcome: binary indicator of recovery, eating disorder psychopathology, weight gain). There was no significant moderation or associations between duration and outcome (ranging from .02-.08), with low to medium heterogeneity. Third, two stand-alone analyses examined outcomes related to weight gain (n = 8) and eating disorder psychopathology (n = 5), with nonsignificant rs of .23/-.06, respectively. High levels of heterogeneity were present. DISCUSSION Duration did not influence treatment outcome across any of our meta-analyses. Increasing homogeneity and power will allow more stable estimates of the impact of duration on outcome to be calculated; to this end, future treatment studies should include outcome related to weight gain (anorexia nervosa) and improvements in eating disorder psychopathology.

Exploring the Eating Disorder Examination Questionnaire, Clinical Impairment Assessment, and Autism Quotient to Identify Eating Disorder Vulnerability: A Cluster Analysis. MACHINE LEARNING AND KNOWLEDGE EXTRACTION 2020.

Abstract
Eating disorders are very complicated and many factors play a role in their manifestation. Furthermore, due to the variability in diagnosis and symptoms, treatment for an eating disorder is unique to the individual. As a result, there are numerous assessment tools available, which range from brief survey questionnaires to in-depth interviews conducted by a professional. One of the many benefits to using machine learning is that it offers new insight into datasets that researchers may not previously have, particularly when compared to traditional statistical methods. The aim of this paper was to employ k-means clustering to explore the Eating Disorder Examination Questionnaire, Clinical Impairment Assessment, and Autism Quotient scores. The goal is to identify prevalent cluster topologies in the data, using the truth data as a means to validate identified groupings. Our results show that a model with k = 2 performs the best and clustered the dataset in the most appropriate way. This matches our truth data group labels, and we calculated our model’s accuracy at 78.125%, so we know that our model is working well. We see that the Eating Disorder Examination Questionnaire (EDE-Q) and Clinical Impairment Assessment (CIA) scores are, in fact, important discriminators of eating disorder behavior.

Abstract
OBJECTIVE Outcome states, such as remission and recovery, include specific duration criteria for which individuals must be asymptomatic. Ideally, duration criteria provide predictive validity to outcome states by reducing symptom-return risk. However, available research is insufficient for deriving specific recommendations for remission or recovery duration criteria for eating disorders. METHOD We intensively modeled the relation between duration criteria length and rates of remission, recovery, and subsequent symptom return in longitudinal data from a treatment-seeking sample of women with anorexia nervosa (AN) and bulimia nervosa (BN). We hypothesized that the length of the duration criterion would be inversely associated with both rates of remission and recovery and with subsequent rates of symptom return. RESULTS Generalized estimating equations supported our hypotheses for all investigated eating-disorder features except for symptom return when using the Psychiatric Status Rating for AN. DISCUSSION We recommend that 6 months be used for remission definitions applied to binge eating, purging, and BN symptom composite measures, whereas no duration criteria be used for low weight and AN symptom composites. We further recommend that 6 months be used for recovery definitions applied to BN symptom composites and AN symptom composites, whereas 18 months be used for individual symptoms of binge eating, purging, and low weight. The adoption of these duration criteria into comprehensive definitions of remission and recovery will increase their predictive validity, which in turn, maximizes their utility.

Abstract
Background Eating disorders (EDs) and substance-related disorders pose a challenge when they co-occur and have implications for patient management. Clinical information on EDs and substance-related disorders as independent disorders is fairly well established in South Africa, but our understanding of the coexistence of these disorders is limited. Aim To determine the prevalence, the concurrent nature and the possible trends of substance use among patients diagnosed with EDs at a South African tertiary hospital over a 21-year period. Setting The ED unit at Tygerberg Hospital, Cape Town, South Africa. Methods We performed a retrospective chart review of 162 patients who were treated for EDs between January 1993 and December 2014. Results The prevalence of ED subtypes was 40.1% bulimia nervosa (BN), 33.3% EDs not otherwise specified (EDNOS) and 26.5% anorexia nervosa. Most participants (71.0%) used at least one substance. Alcohol was the most prevalent substance of choice (54.8%). Most patients had an additional psychiatric disorder (62.3%), of which major depressive disorder was the most prevalent (46.3%). Apart from the use of alcohol and cannabis, which remained consistent, the use of most other substances as well as the prevalence of BN declined during the study period. Conclusion Understanding the prevalence and trends of EDs and the corresponding patterns of substance misuse is essential to improve service provision. This study emphasises the need to better understand the ongoing and changing behavioural trends in EDs to improve patient management.

Abstract
OBJECTIVE The present meta-analysis evaluated changes in individuals' risk of engaging in distinct disordered eating behaviors (DEBs) in the long-term. METHOD Longitudinal studies assessing changes in DEBs via ≥2 assessments with a time lag of ≥10 years were included. Risk ratios were calculated for baseline to 10-14.9-year (M = 11.04) follow-up and baseline to ≥15-year (M = 18.62) follow-up changes in the use of binge eating, multiple purging, self-induced vomiting, laxatives, diuretics, diet pills, compensatory exercising, fasting/dieting, and multiple DEBs; Cohen's d was used for continuous binge-eating plus purging variable changes. Subgroup and meta-regression analyses tested whether eating disorder (ED) clinical sample versus nonclinical sample status, female versus male sex/gender, higher versus lower study bias, and baseline mean age and body mass index influenced overall effect magnitude for analyses with sufficient data. RESULTS Seventeen studies (26 [sub]samples) were included. Overall, individuals' risk of engaging in various restrictive eating and other compensatory behaviors decreased over time and the magnitudes of risk reductions for the use of certain compensatory DEBs were larger over longer follow-up durations. Specifically, for significant DEB change models, risk reductions spanned from 20.0-39.8% for 10-year follow-up and 24.7-74.8% for ≥15-year follow-up. However, nuances were found in the nature of these DEB changes as a function of DEB type, follow-up length, ED versus nonclinical sample composition, and baseline mean age. CONCLUSIONS These findings provide important information that can help identify treatment priorities and suggest that targeted and tailored preventative ED treatments warrant consistent implementation at the community-level, particularly for youth.

Abstract
Given the high rates of comorbidity between eating disorders (EDs) and substance use disorders (SUDs), it is important to develop effective treatment approaches for individuals with both an ED and SUD (ED-SUD). To date, there is limited information guiding the concurrent treatment of these disorders. To build on existing research, the present study compared adult patients with ED-SUD (n = 36) to patients with ED-only (n = 62) in terms of demographics, psychiatric comorbidity, and self-reported eating disorder and related psychopathology. Results indicated that ED-SUD patients had a higher number of psychiatric comorbidities, were more likely to be prescribed mood stabilizers, and were more sensitive to reward. They also reported greater difficulty with emotion regulation, including more difficulty engaging in goal-directed activity, higher impulsivity, and more limited access to emotion regulation strategies. These differences highlight the importance of targeting emotion dysregulation for ED-SUD, and provide evidence for the importance of integrated, transdiagnostic treatment to simultaneously address the SUD, ED, and other psychiatric comorbidities. Implications for tailoring treatment are discussed with a focus on Dialectical Behavior Therapy (DBT).

Abstract
Bulimia Nervosa (BN) is a serious eating disorder, which affects 0.8-2.9% of the young population. The etiology is unknown and biomarkers would support in understanding the pathophysiology of BN, and in identifying BN patients that may benefit from medical treatment. This systematic review aims to answer whether (a) BN deviate from healthy controls in terms of serotonin (5-HT) biomarkers in blood, and whether (b) blood-based 5-HT biomarkers could be used to tailor psychopharmacological treatment in BN. A literature search using PubMed, PsycINFO and Embase was done using the following search terms: "Bulimia Nervosa" AND "serotonin" AND "blood" OR "plasma" OR "serum". 32 studies were included in this systematic review. Several biomarkers and challenge tests were identified and all studies described an association with BN and dysregulation of the 5-HT system compared to healthy controls. Several studies pointed to an association also to borderline symptoms in BN. BN deviate from healthy controls in terms of 5-HT biomarkers in blood supporting an abnormal 5-HT system in BN. 5-HT biomarkers and associated methods could be used to tailor treatment in BN although as yet, most tests described are unpractical for bedside use.

Abstract
OBJECTIVE In psychiatry, the presence of residual symptoms after treatment is linked to the definitions of remission and recovery. To identify the presence of residual eating disorder (ED) symptoms and associated non-ED clinical features in remitted and recovered EDs, the current systematic review with meta-analysis was performed. METHOD A systematic review was conducted on residual ED symptoms and non-ED clinical features including comorbid psychopathology, neurophysiological functioning, cognitive functioning, and quality of life in ED patients considered remitted or recovered. To examine residual ED symptoms, meta-analyses were performed while considering age, study quality, remission, and recovery criteria strictness as moderators. Sensitivity, publication bias, and heterogeneity analyses were also conducted. RESULTS The 64 studies selected for the systematic review underscored the presence of residual ED symptoms in anorexia nervosa (AN) and bulimia nervosa (BN), and impairments and deficits in the additional features examined. From the 64 studies, 31 were selected regarding residual ED symptoms in AN for meta-analysis. Large effect sizes indicated that remitted/recovered AN patients reported significantly lower body mass index (Hedges' g = -0.62[-0.77, -0.46]) and significantly greater symptomatology in terms of ED examination-questionnaire (Hedges'g = 0.86 [0.48,1.23]) and ED inventory (Hedges' g = 0.94[0.64,1.24]) than healthy controls, independently of remission and recovery criteria strictness, age, and study quality. DISCUSSION The presence of residual ED symptoms in AN is quantitatively supported, whereas the presence of residual ED symptoms in BN should be further investigated. Data on binge-eating disorder are missing. Future research should use consistent, multicomponent, and standardized comparable indicators of recovery.

Abstract
BACKGROUND Bulimia nervosa (BN) is associated with increased mortality. Frequent comorbidities of BN include substance use disorders, affective disorders and personality disorders (PD). These comorbidities may add an additional risk for mortality. METHODS We investigated the influence of these psychiatric comorbidities on all-cause mortality with demographic and socioeconomic factors considered as confounders over an observation period from January 2007 to March 2016 for 1501 people with BN using anonymised health records data from the South London and Maudsley NHS Foundation Trust (SLaM), retrieved through its Clinical Records Interactive Search (CRIS) data resource. Mortality was ascertained through monthly linkages to the nationwide tracing system administered by the Office for National Statistics (ONS). We used Cox proportional hazards regression to calculate hazard ratios (HRs) with 95% confidence intervals (CIs). Multivariable analyses were also performed to estimate effects when controlling for confounding of age, sex, ethnicity, borough, marital status and deprivation score. RESULTS A total of 18 patients with BN died during the observation period. The standardised mortality ratio (SMR) for our study cohort (against the population of England and Wales in 2012 as a standard) was 2.52 (95% CI 1.49-3.97). Cox regressions revealed significant associations of mortality with older age and male gender. Comorbid PD (HR: 3.36; 95% CI 1.05-10.73) was significantly associated with all-cause mortality, even after controlling for demographic and socioeconomic covariates. CONCLUSIONS These results highlight increased mortality in patients with BN and the importance of recognising and treating PDs in patients with BN.

Abstract
OBJECTIVE To assess the long-term outcome and identify outcome predictors in a very large sample of inpatients treated for bulimia nervosa (BN). METHOD Out of a total of 2,033 patients admitted consecutively to specialized treatment, 1,351 patients (mean age at treatment 25.94) were assessed for follow-up on average 11 (SD 6) years after admission. Also a very long-term (21 years) subsample (N = 147; mean age 25.92) was defined. Bivariate and logistic regression analyses identified predictors of poor outcome. RESULTS For more than 70% of the patients follow-up information could be gathered. Severity of eating disorder (ED) and other symptoms decreased over time but remained higher than in healthy controls, using published normative data. Remission rate was 38% after 11 years and 42% in the subsample after 21 years. Out of the total sample of N = 2,033 patients, 49 had died (2.4%). Persistent BN was found in 14.2% and the most frequent crossover was to ED not otherwise specified. Predictors of poor outcome were fewer follow-up years, higher drive for thinness, higher age at treatment, and less global functioning. DISCUSSION Based on clinical indicators, patients presented with a high level of ED and psychiatric symptomatology. With less than half of the patients remitted after 22 years, efforts are needed to improve treatment outcome.

Abstract
OBJECTIVE We examined whether eating disorder (ED) outcome trajectories during residential treatment differed for patients screening positive for comorbid borderline personality disorder (BPD) and/or substance use disorders (SUDs) than those who do not. METHOD We examined data from patients in a residential ED treatment program. Patients completed validated self-report surveys to screen for SUDs and BPD on admission, and the ED Examination-Questionnaire (EDE-Q) on admission and every 2 weeks until discharge (N = 479 females). RESULTS Fifty-four percent screened positive for at least one co-occurring condition. At admission, patients screening positive for SUD and/or BPD had significantly greater eating pathology than patients screening negative for both (t[477] = 8.23, p < .001). Patients screening positive for SUD (independent of BPD screening status) had a significantly faster rate of symptom improvement during the initial 4 weeks than patients screening positive for BPD only and those with no comorbidities. DISCUSSION Screening positive for SUD and/or BPD was common in residential ED treatment, and associated with more severe ED symptoms. Screening positive for SUD was associated with faster ED symptom improvement than screening positive for BPD. These findings suggest that intensive ED treatment, even in the absence of intensive SUD treatment, may enhance patient outcomes for those with SUDs.

Abstract
OBJECTIVE According to Fairburns transdiagnostic model of eating disorders (EDs), high levels of perfectionism and low self-esteem are two core traits across EDs. This study investigates the role of self-esteem as a transdiagnostic moderator of the relationship between perfectionism and ED symptoms across EDs. METHOD A large group of patients (n = 732) completed several questionnaires measuring perfectionism, self-esteem, and disordered eating symptomatology, more specifically, drive for thinness (DFT) and body dissatisfaction (BD). RESULTS Across EDs, self-esteem served as a moderator for the association between perfectionism and DFT. However, by testing the model for DFT in each ED separately, the effect only remained in patients with anorexia nervosa and ED not otherwise specified. When testing the model for BD, no moderation effect was found in any of the included EDs. CONCLUSIONS This study found that the interaction between perfectionism and self-esteem on DFT can be seen as transdiagnostic, although this effect is not found in each ED separately. These results suggest that ED treatment should consider to not only focus on transdiagnostic factors but also look at the specific impairments of each individual ED.

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

Abstract
Cognitive behavioral therapy (CBT) is regarded as the gold-standard treatment for bulimia nervosa (BN), yet despite impressive empirical support for its effectiveness, over 50% of patients fail to achieve abstinence from binge eating and purging by the end of treatment. One factor that may contribute to reduced efficacy rates in CBT is weight suppression (WS; the difference between a person's highest weight ever at their adult height and current weight). A growing body of research indicates that WS in patients with BN may have a clinically significant effect on symptomatology and prognosis. However, the current cognitive behavioral framework for BN does not explicitly acknowledge the role of WS in the onset or maintenance of BN symptoms and does not provide guidance for clinicians on how to address WS during treatment. The relationship between WS, biological pressure to regain lost weight, and the maintenance of BN symptoms suggest that current cognitive behavioral models of BN may be improved by considering the role of WS and exploring needed treatment modifications. Indeed, a reconceptualization of existing models may offer insight into potential strategies that can be used to reduce the susceptibility to treatment dropout, nonresponse, and relapse. It is therefore necessary to consider whether, and how, clinicians' consideration of WS during case conceptualization and treatment planning could serve to improve CBT outcomes. The current review explores ways in which high WS could contribute to poor CBT outcomes, provides preliminary clinical recommendations for incorporating WS into existing cognitive behavioral treatments based on extant data and clinical wisdom, and proposes suggestions for future research needed in this domain.

Abstract
OBJECTIVE The objective of this study was to investigate predictors of long-term recovery from eating disorders 22 years after entry into a longitudinal study. METHOD One hundred and seventy-six of the 228 surviving participants (77.2%) were re-interviewed 20-25 years after study entry using the Longitudinal Interval Follow-up Evaluation to assess ED recovery. The sample consisted of 100 women diagnosed with anorexia nervosa (AN) and 76 with bulimia nervosa (BN) at study entry. RESULTS A comorbid diagnosis of major depression at the start of the study strongly predicted having a diagnosis of AN-Restricting type at the 22-year assessment. A higher body mass index (BMI) at study intake decreased the odds of being diagnosed with AN-Binge Purge type, relative to being recovered, 22 years later. The only predictor that increased the likelihood of having a diagnosis of BN at the 22-year assessment was the length of time during the study when the diagnostic criteria for BN were met. CONCLUSIONS Together, these results indicate that the presence and persistence of binge eating and purging behaviors were poor prognostic indicators and that comorbidity with depression is particularly pernicious in AN. Treatment providers might pay particular attention to these issues in an effort to positively influence recovery over the long-term.

Abstract
Individuals with bulimia nervosa (BN) engage in episodes of binge eating, marked by loss of control and eating despite fullness. Does altered reward and metabolic state contribute to BN pathophysiology? Normally, hunger increases (and satiety decreases) reward salience to regulate eating. We investigated whether BN is associated with an abnormal response in a neural circuit involved in translating taste signals into motivated behavior, when hungry and fed. Twenty-six women remitted from BN (RBN) and 22 control women (CW) were administered water and sucrose during 2 counterbalanced fMRI visits, following a 16-hr fast or a standardized breakfast. Significant Group × Condition interactions were found in the left putamen, insula, and amygdala. Post hoc analyses revealed CW were significantly more responsive to taste stimuli when hungry versus fed in the left putamen and amygdala. In contrast, RBN response did not differ between conditions. Further, RBN had greater activation in the left amygdala compared with CW when fed. Findings suggest that RBN neural response to rewarding stimuli may not be modulated by metabolic state. Data raise the possibility that disinhibited eating in BN could result from a failure to devalue food reward when fed, resulting in an exaggerated response. (PsycINFO Database Record

Abstract
This article aims to shed light on the self-perceptions of people with eating disorders in Malta and Italy through a deep understanding of their narratives. In contrast to the biomedical perception of the phenomenon and in opposition with the prevalent feminist theories on the subject, I consider eating disorders as the result of self-transformative processes. I suggest that anorexics, bulimics and binge eaters are actively and deliberately engaged in a project of moral self-transformation that is culturally defined. The moral transformations of women with eating disorders in Malta and Italy, the two considered contexts of this research, reflect the social expectations of women in these societies. The drastic changes in personal attitudes towards both food and the body that characterise eating disorders are the result of a complete dedication to the moral values embodied in thinness, namely the control of bodily needs and pleasure. The self-transformative process of people with eating disorders can be understood as a form of moral conversion along a continuum of increasing control over hunger: the higher the control, the higher the level of satisfaction and the degree of moral conversion achieved. Considering the general low recovery rates of people with eating disorders, this approach helps in the understanding of why people who are diagnosed with an eating disorder accept medical definitions and treatments to different extents.

Abstract
BACKGROUND Anorexia nervosa is a severe, biologically based brain disorder with significant medical complications. It is critical that new, effective treatments are developed to interrupt the persistent course of the illness due to the medical and psychological sequelae. Several psychosocial, behavioral and pharmacologic interventions have been investigated in adult anorexia nervosa; however, evidence shows that their impact is weak and treatment effects are generally small. METHOD This paper describes a new neurobiological anorexia nervosa model that shifts focus from solely external influences, such as social and family, to include internal influences that integrate genetic and neurobiological contributions, across the age span. The model serves as a theoretical structure for a new, five-day treatment, outlined in this paper, targeting anorexia nervosa temperament, which integrates neurobiological dimensions into evidence-based treatment interventions. The treatment is in two phases. Phase I is a five day, 40 hour treatment for anorexia nervosa adults. Phase II is the follow-up and is currently being developed. RESULTS Preliminary qualitative acceptability data on 37 adults with anorexia nervosa and 60 supports (e.g., spouses, parents, aunts, friends, partners, children of anorexia nervosa adults) are promising from Phase I. Clients with anorexia nervosa and their supports report that learning neurobiological facts improved their understanding of the illness and helped equip them with better tools to manage anorexia nervosa traits and symptoms. In addition, nutritional knowledge changed significantly. CONCLUSIONS This is the first neurobiologically based, five-day treatment for adults with anorexia nervosa and their supports. It is a new model that outlines underlying genetic and neurobiological contributions to anorexia nervosa that serves as a foundation to treat both traits and symptoms. Preliminary qualitative findings are promising, with both clients and supports reporting that the neurobiological treatment approach helped them better understand the illness, while better conceptualizing how to respond to their traits and manage their symptoms. Data in Phase I shows promise as a neurobiologically based intervention for anorexia nervosa, and it serves as a foundation for the development of Phase II. Evidence of ongoing program efficacy will be described as data are reported on Phase II. TRIAL REGISTRATION NCT NCT02852538 Registered 1 August 2016.

Abstract
BACKGROUND Impaired inhibitory control is considered a behavioural phenotype in patients with bulimia nervosa. However, the underlying neural correlates of impaired general and food-specific behavioural inhibition are largely unknown. Therefore, we investigated brain activation during the performance of behavioural inhibition to general and food-related stimuli in adults with bulimia nervosa. METHODS Women with bulimia and healthy control women underwent event-related fMRI while performing a general and a food-specific no-go task. RESULTS We included 28 women with bulimia nervosa and 29 healthy control women in our study. On a neuronal level, we observed significant group differences in response to general no-go stimuli in women with bulimia nervosa with high symptom severity; compared with healthy controls, the patients showed reduced activation in the right sensorimotor area (postcentral gyrus, precentral gyrus) and right dorsal striatum (caudate nucleus, putamen). LIMITATIONS The present results are limited to adult women with bulimia nervosa. Furthermore, it remains unclear whether impaired behavioural inhibition in patients with this disorder are a cause or consequence of chronic illness. CONCLUSION Our findings suggest that diminished frontostriatal brain activation in patients with bulimia nervosa contribute to the severity of binge eating symptoms. Gaining further insight into the neural mechanisms of behavioural inhibition problems in individuals with this disorder may inform brain-directed treatment approaches and the development of response inhibition training approaches to improve inhibitory control in patients with bulimia nervosa. The present study does not support greater behavioural and neural impairments to food-specific behavioural inhibition in these patients.

Abstract
OBJECTIVE Individuals with bulimia nervosa (BN) frequently endorse risky behaviors such as self-harm and substance use. However, no studies of BN to date have examined factors associated with engaging in individual or co-occurring risky behaviors. Given that individuals with BN often have personality psychopathology, which has been linked to symptoms and course of illness, this study sought to examine how personality may differentiate engagement in risky behaviors among BN individuals. METHOD A sample of 133 women with BN completed self-report measures of personality psychopathology at baseline, and then reported on bulimic and risky behaviors (e.g., substance misuse, self-harm) over 2 weeks using ecological momentary assessment. A series of hierarchical multiple regression analyses were conducted to examine the unique associations between state-level predictor variables (each risky behavior, e.g., substance misuse, and combination of risky behaviors, e.g., substance misuse plus self-harm) and trait-level personality constructs. RESULTS Substance misuse behavior, above and beyond all other risky behaviors, was significantly associated with higher scores on trait dissocial behavior (P = 0.004). DISCUSSION Substance misuse in BN has a unique association with dissocial behavior, a personality trait characterized by hostility, impulsivity, and entitlement. These results suggest that targeting personality variables may help facilitate more effective treatment of risky behaviors, including substance use in BN. © 2016 Wiley Periodicals, Inc.

Abstract
This article reviews the most recent treatment literature for anorexia nervosa, bulimia nervosa, and binge eating disorder and serves as a guide for recommended readings and therapist resources. The primary focus is on empirically tested treatment modalities; for each of these approaches reviewed, the theoretical background, nature of the intervention, and existing empirical support are summarized. The article also presents less researched, albeit promising, approaches to eating disorder treatment, describing the rationale and available research. A focus on multicultural issues, including the paucity of eating disorder treatment research among participants of color, and suggestions for building research and enhancing treatment effectiveness with ethnic minority clients, is incorporated throughout. Recommendations concerning pressing research needs are made, and a summary of clinical recommendations for each disorder is formulated.

Abstract
The effectiveness of an individualized outpatient program was investigated in the treatment of bulimia nervosa (BN) and anorexia nervosa (AN). Participants included 151 females who received outpatient eating disorder treatment in the partial hospitalization program, the intensive outpatient program, or a combination of the two programs. Outcome measures included the Eating Disorder Inventory (EDI-2), Beck Depression Inventory (BDI-II), frequency of binge eating and purging, and mean body weight. Findings included significant increases in weight for the AN group, reductions in binge eating frequency for the BN group, and reductions in EDI-2 and BDI-II scores and purging frequency for both groups. This study provides preliminary support for the efficacy of a multimodal program for the treatment of both anorexia nervosa and bulimia nervosa.

Abstract
Anorexia nervosa (AN) is a severe and debilitating disorder with significant medical and psychological sequelae. To date, there are no effective treatments for adults, resulting in high rates of chronicity, morbidity, and mortality. Recent advances in brain imaging research have led to an improved understanding of etiology and specific neurobiological mechanisms underlying symptoms. Despite this, there are no treatments focused on targeting symptoms using this empirically supported mechanistic understanding of the illness. Updated treatment approaches focused on targeting neurobiological mechanisms underlying core AN symptomatology are necessary to improve treatment out-comes for this population. Neurobiologically Enhanced With Family Eating Disorder Trait Response Treatment (NEW FED TR) is a neurobiologically informed treatment targeting key temperament constructs associated with the illness through the delivery of psychoeducation and skills training to patients and nominated carers.

Abstract
The purpose of this study was to determine clinically significant change criteria and change trajectories for the Change in Eating Disorder Symptoms Scale (CHEDS). Participants included non-eating disordered (n=95) and eating disordered (n=58) samples. The clinical sample was undergoing enhanced cognitive-behavior therapy (CBT-E) for eating disorders. Reliable change indices (RCI), cutscores, and change trajectories were calculated. CHEDS total score RCI was 12 points while the cutscore between eating disordered and non-eating disordered groups was 65. Trajectory models for benchmarking were successfully derived based on initial scores. The change indices and trajectories permit session-by-session analyses and benchmarking of change. These empirically-calibrated indices of patient change and progress allow for empirically-guided treatment decision-making.

Abstract
OBJECTIVE Understanding the factors that predict a favourable outcome following specialist treatment for an eating disorder may assist in improving treatment efficacy, and in developing novel interventions. This review and meta-analysis examined predictors of treatment outcome and drop-out. METHOD A literature search was conducted to identify research investigating predictors of outcome in individuals treated for an eating disorder. We organized predictors first by statistical type (simple, meditational, and moderational), and then by category. Average weighted mean effect sizes (r) were calculated for each category of predictor. RESULTS The most robust predictor of outcome at both end of treatment (EoT) and follow-up was the meditational mechanism of greater symptom change early during treatment. Simple baseline predictors associated with better outcomes at both EoT and follow-up included higher BMI, fewer binge/purge behaviors, greater motivation to recover, lower depression, lower shape/weight concern, fewer comorbidities, better interpersonal functioning and fewer familial problems. Drop-out was predicted by more binge/purge behaviors and lower motivation to recover. For most predictors, there was large interstudy variability in effect sizes, and outcomes were operationalized in different ways. There were generally insufficient studies to allow analysis of predictors by eating disorder subtype or treatment type. DISCUSSION To ensure that this area continues to develop with robust and clinically relevant findings, future studies should adopt a consistent definition of outcome and continue to examine complex multivariate predictor models. Growth in this area will allow for stronger conclusions to be drawn about the prediction of outcome for specific diagnoses and treatment types.

Abstract
Bulimia nervosa (BN) is a serious eating disorder that can persist for years and contribute to medical complications and increased mortality, underscoring the need to better understand factors maintaining this disorder. Higher levels of weight suppression (WS) have been found to predict both the onset and maintenance of BN; however, no studies have examined mechanisms that may account for the effects of WS on BN. We hypothesized that high WS would lead to reduced leptin levels, which may increase risk of binge eating by modulating reward responses to food. The current study examined the relationship between WS, leptin levels, and the reinforcing value of food in women with BN (n = 32) and noneating disorder controls (n = 30). Participants provided information on WS, completed a fasting blood draw to obtain serum leptin, and completed a progressive ratio task to measure the reinforcing value of food. Individuals with BN had greater WS (p < .01) and reinforcing food value (p < .05) compared with controls. Additionally, higher WS was associated with both lower leptin (p < .05) and increased reinforcing value of food (p < .05). Contrary to hypotheses, BN and control participants did not differ on leptin levels, and leptin levels were not significantly associated with the reinforcing value of food. Findings support that efforts to conform to the thin ideal may alter drive to consume rewarding foods and leave women vulnerable to binge episodes. However, mechanisms through which WS contributes to food reward and binge eating remain unknown.

Abstract
Eating disorders (EDs) are serious psychiatric conditions influenced by biological, psychological, and sociocultural factors. A better understanding of the genetics of these complex traits and the development of more sophisticated molecular biology tools have advanced our understanding of the etiology of EDs. The aim of this review is to critically evaluate the literature on the genetic research conducted on three major EDs: anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). We will first review the diagnostic criteria, clinical features, prevalence, and prognosis of AN, BN, and BED, followed by a review of family, twin, and adoption studies. We then review the history of genetic studies of EDs covering linkage analysis, candidate gene association studies, genome-wide association studies, and the study of rare variants in EDs. Our review also incorporates a translational perspective by covering animal models of ED-related phenotypes. Finally, we review the nascent field of epigenetics of EDs and a look forward to future directions for ED genetic research.

Abstract
The primary defining characteristic of a diagnosis of an eating disorder (ED) is the "disturbance of eating or eating-related behavior that results in the altered consumption or absorption of food" (DSM V; American Psychiatric Association, 2013). There is a spectrum, ranging from those who severely restrict eating and become emaciated on one end to those who binge and overconsume, usually accompanied by some form of compensatory behaviors, on the other. How can we understand reasons for such extremes of food consummatory behaviors? Recent work on obesity and substance use disorders has identified behaviors and neural pathways that play a powerful role in human consummatory behaviors. That is, corticostriatal limbic and dorsal cognitive neural circuitry can make drugs and food rewarding, but also engage self-control mechanisms that may inhibit their use. Importantly, there is considerable evidence that alterations of these systems also occur in ED. This paper explores the hypothesis that an altered balance of reward and inhibition contributes to altered extremes of response to salient stimuli, such as food. We will review recent studies that show altered sensitivity to reward and punishment in ED, with evidence of altered activity in corticostriatal and insula processes with respect to monetary gains or losses, and tastes of palatable foods. We will also discuss evidence for a spectrum of extremes of inhibition and dysregulation behaviors in ED supported by studies suggesting that this is related to top-down self-control mechanisms. The lack of a mechanistic understanding of ED has thwarted efforts for evidence-based approaches to develop interventions. Understanding how ED behavior is encoded in neural circuits would provide a foundation for developing more specific and effective treatment approaches.

Abstract
Many research diagnostic interviews employ skip rules, such that some questions are only asked based on answers to prior questions. In the context of large-scale epidemiological studies, skip rules are important to study feasibility by reducing the time, money, and participant burden required for assessment. However, less is understood about information lost when questions are skipped. This study examines the relative prevalence, clinical significance, and additional time required to assess eating disorder symptom patterns skipped in the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) to understand the costs and benefits of following skip rules. Data come from the second stage of a two-stage cohort sample (N = 400) in which the SCID-I eating disorders module was administered without following skip rules. Results were weighted to correct for the sampling framework. Over a third of subjects endorsed symptoms that would have been missed had skip rules been followed. Uncaptured symptom patterns were associated with increased psychosocial impairment, and the additional time required to assess all symptoms averaged 1.8 minutes per participant. Clinically significant symptom patterns are missed by the SCID-I and similar diagnostic tools, suggesting that epidemiologic studies using such instruments under-estimate the prevalence and public health impact of mental disorders.

Abstract
Anorexia nervosa (AN) tends to be a chronic and deadly disorder with no proven treatments that reverse core symptoms in adults. New insight into neurobiological mechanisms that contribute to symptoms may support development of more effective interventions. We describe the development of a temperament-based treatment for AN on the basis of empirically supported models. It uses a systemized approach and takes into consideration an understanding of how neurobiological mechanisms are expressed through behaviour and personality and contribute to specific AN symptomatology. This model integrates the development of AN-focused constructive coping strategies with carer-focused strategies to manage temperament traits that contribute to AN symptomatology. This intervention is consistent with the recent Novel Interventions for Mental Disorders initiative mandating that treatment trials follow an experimental medicine approach by identifying underlying mechanisms that are directly targeted by the intervention to influence symptoms.

Abstract
OBJECTIVE Studies of age of first binge have been conducted in clinical samples of patients with bulimia nervosa (BN) and binge eating disorder (BED), but few studies have examined age of first binge using nationally representative samples. METHOD We examined age of first binge and its clinical correlates using data generated from the National Women's Study (n = 3,006). Participants who endorsed ever binge eating (n = 707) were divided into two groups: (1) child-adolescent onset (CO)--age of first binge <18 years, and (2) adult onset (AO)--age of first binge ≥18 years. We hypothesized that CO binge eating would be associated with greater (1) likelihood of developing BN/BED, (2) severity of BN/BED, (3) history of trauma and PTSD, and (4) history of psychiatric comorbidity, such as major depression and substance use. RESULTS Of those who ever endorsed binge eating, 212 reported CO (30%) and 495 (70%) reported AO. Although AO binge eating was more common, CO binge eating was associated with higher rates of lifetime BN, greater severity of bulimic symptoms, earlier age of first dieting; earlier age at highest weight, greater likelihood of ED treatment, and higher rates of molestation, physical assault, any direct victimization, lifetime PTSD, and substance abuse. CONCLUSIONS AO binge eating is more than twice as common as CO binge eating in women, but CO binge eating is associated with higher rates of lifetime BN, greater severity of BN, and higher rates of victimization, PTSD, and substance abuse.

Abstract
BACKGROUND Recent evidence suggests increased risk for mortality in bulimia nervosa (BN). However, little is yet known about suicidal behavior in BN. AIMS To examine frequency and correlates of suicidal ideation and attempts in adolescents and adults with BN in two population-based samples. METHOD A total of 10,123 adolescents and 2980 adults in two nationally representative surveys of mental disorder were queried regarding eating disorder symptoms and suicidal ideation and attempts. RESULTS Less than 1 percent (0.9%) of adolescents and 1.0% of adults met the criteria for BN. Suicidal ideation was more common among adolescents with BN (53.0%) compared with those with binge eating disorder (BED) (34.4%), other psychopathology (21.3%) or no psychopathology (3.8%). Similar trends emerged for the association between BN and self-reported suicidal plans or attempts. Among adults, suicidality was more common in BN than in the no psychopathology group, but not significantly different from the anorexia nervosa (AN), BED, or other psychopathology subgroups. CONCLUSION There is a high risk of suicidal ideation and behavior among those with BN. These results underscore the importance of addressing suicide risk in adolescents and adults with eating disorder symptoms.

Abstract
BACKGROUND Individuals with anorexia nervosa (AN) are often cognitively rigid and behaviorally over-controlled. We previously showed that adult females recovered from AN relative to healthy comparison females had less prefrontal activation during an inhibition task, which suggested a functional brain correlate of altered inhibitory processing in individuals recovered from AN. However, the degree to which these functional brain alterations are related to disease state and whether error processing is altered in AN individuals is unknown. METHODOLOGY/PRINCIPAL FINDINGS In the current study, ill adolescent AN females (n = 11) and matched healthy comparison adolescents (CA) with no history of an eating disorder (n = 12) performed a validated stop signal task (SST) during functional magnetic resonance imaging (fMRI) to explore differences in error and inhibitory processing. The groups did not differ on sociodemographic variables or on SST performance. During inhibitory processing, a significant group x difficulty (hard, easy) interaction was detected in the right dorsal anterior cingulate cortex (ACC), right middle frontal gyrus (MFG), and left posterior cingulate cortex (PCC), which was characterized by less activation in AN compared to CA participants during hard trials. During error processing, a significant group x accuracy (successful inhibit, failed inhibit) interaction in bilateral MFG and right PCC was observed, which was characterized by less activation in AN compared to CA participants during error (i.e., failed inhibit) trials. CONCLUSION/SIGNIFICANCE Consistent with our prior findings in recovered AN, ill AN adolescents, relative to CA, showed less inhibition-related activation within the dorsal ACC, MFG and PCC as inhibitory demand increased. In addition, ill AN adolescents, relative to CA, also showed reduced activation to errors in the bilateral MFG and left PCC. These findings suggest that altered prefrontal and cingulate activation during inhibitory and error processing may represent a behavioral characteristic in AN that is independent of the state of recovery.

Abstract
Changes in ovarian hormones predict changes in emotional eating across the menstrual cycle. However, prior studies have not examined whether the nature of associations varies across dysregulated eating severity. The current study determined whether the strength and/or nature of hormone/dysregulated eating associations differ based on the presence of clinically diagnosed binge episodes (BEs). Participants included 28 women with BEs and 417 women without BEs who provided salivary hormone samples, ratings of emotional eating, and BE frequency for 45 days. Results revealed stronger associations between dysregulated eating and ovarian hormones in women with BEs as compared to women without BEs. The nature of associations also differed, as progesterone moderated the effects of lower estradiol levels on dysregulated eating in women with BEs only. Although hormone/dysregulated eating associations are present across the spectrum of pathology, the nature of associations may vary in ways that have implications for etiological models and treatment.

Abstract
Women with bulimia nervosa (BN) frequently have co-occurring alcohol use disorders (AUDs). Studies of shared genetic transmission of these disorders have been mixed. Personality heterogeneity among individuals with BN may explain discrepant findings. Cluster analysis has characterized women with BN in groups on the basis of personality profiles. One group, the Dysregulated cluster, characterized largely by behavioural disinhibition and emotional dysregulation may be more closely linked etiologically to AUDs. This study examined whether genetic associations between BN and AUDs are the strongest among the Dysregulated cluster. Symptoms of BN and AUDs were assessed in female twins at ages 17 and 25 years from the Minnesota Twin Family Study. Personality clusters were defined using the Multidimensional Personality Questionnaire. Twin moderation models suggested small-to-moderate common genetic transmission between BN and AUDs. However, shared genetic effects did not differ by personality cluster. Findings suggest that personality clusters are unlikely to account for inconsistent findings regarding their shared aetiology.

Abstract
OBJECTIVE To compare remission rates, determine level of agreement and identify quality of life (QoL) distinctions across a broad spectrum of remission definitions among patients with eating disorders (ED). METHODS Women (N=195; 94 AN, 24 BN, and 77 EDNOS) from inpatient and partial hospital ED programs participated in a study of treatment outcomes. Remission rates were evaluated with percentages, kappa coefficients identified level of agreement and Mann-Whitney-Wilcoxon tests with Bonferroni corrections determined differences in quality of life between remitted and not remitted patients by remission definition. RESULTS Depending on remission definition used, the percent of remitted patients varied from 13.2% to 40.5% for AN, 15.0% to 47.6% for BN and 24.2% to 53.1% for EDNOS. Several definitions demonstrated "very good" agreement across diagnoses. Remission was associated with higher quality of life in psychological, physical/cognitive, financial and work/school domains on a disease-specific measure, and in mental but not physical functioning on a generic measure. CONCLUSIONS Remission rates vary widely depending on the definition used; several definitions show strong agreement. Remission is associated with quality of life, and often approximates scores for women who do not have an eating disorder. The ED field would benefit from adopting uniform criteria, which would allow for more accurate comparison of remission rates across therapeutic interventions, treatment modalities and facilities. We recommend using the Bardone-Cone criteria because it includes assessment of psychological functioning, was found to be applicable across diagnoses, demonstrated good agreement, and was able to distinguish quality of life differences between remitted and not remitted patients.

Hard exercise, affect lability, and personality among individuals with bulimia nervosa. Eat Behav 2013; 14:413-9. [PMID: 24183126 PMCID: PMC3832258 DOI: 10.1016/j.eatbeh.2013.07.004] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2012] [Revised: 06/30/2013] [Accepted: 07/15/2013] [Indexed: 11/24/2022]
Abstract
The current study explores the personality traits of compulsivity (e.g., sense of orderliness and duty to perform tasks completely) and restricted expression (e.g., emotion expression difficulties) as potential moderators of the relation between affect lability and frequency of hard exercise episodes in a sample of individuals with bulimic pathology. Participants were 204 adult females recruited in five Midwestern cities who met criteria for threshold or subthreshold bulimia nervosa (BN). Compulsivity was found to significantly moderate the relation between affect lability and number of hard exercise episodes over the past 28 days, such that among those with high compulsivity, level of affect lability was associated with the number of hard exercise episodes; whereas, among those with low compulsivity, affect lability was not associated with the number of hard exercise episodes. The same pattern of findings emerged for restricted expression; however, this finding approached, but did not reach statistical significance. As such, it appears that affect lability is differentially related to hard exercise among individuals with BN depending upon the level of compulsivity and, to a more limited extent, restricted expression. These results suggest that, for individuals with BN with either compulsivity or restricted expression, focusing treatment on increasing flexibility and/or verbal expression of emotions may help in the context of intense, fluctuating affect.

Pretreatment outcome indicators in an eating disorder outpatient group: the effects of self-esteem, personality disorders and dissociation. Compr Psychiatry 2013; 54:933-42. [PMID: 23642630 DOI: 10.1016/j.comppsych.2013.03.024] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2012] [Revised: 03/02/2013] [Accepted: 03/19/2013] [Indexed: 11/23/2022] Open
Abstract
OBJECTIVE The prognosis for eating disorders (ED) is unsatisfactory, and the literature about outcome indicators is controversial. The present study evaluates the roles of self-esteem, personality disorders (PD), and dissociation as outcome predictors. METHOD Fifty-seven ED outpatients were recruited from a population beginning a Cognitive Behavioral Therapy-Enhanced (CBT-E) treatment. All patients received the Structured Clinical Interview for DSM-IV Axis I (SCID-I), the Structured Clinical Interview for DSM-IV Axis II (SCID-II), and completed the Eating Disorder Examination Questionnaire (EDE-Q), the Dissociation Questionnaire (DIS-Q), and the Rosenberg Self-Esteem Scale (RSES). One month after the end of treatment, recovery was evaluated as meeting the DSM-IV criteria for EDs. RESULTS A small group of patients recovered (42.2%). Low self-esteem and dissociation results correlated with a negative outcome. DISCUSSION Dissociation may be an important moderator of psychotherapy and treatment success, as already suggested by previous studies on non-eating-related disorders.
