This exploratory study aimed to describe the lived experiences of queer women affected by eating and weight-related concerns. Qualitative data from young queer women ( n  = 105; Age = 23.6 ± 3.4 years) with eating and weight-related concerns in response to open-ended questions related to the influence of gender identity and body image on weight concern, behaviours, and perception were analysed using reflexive thematic analysis. Nine themes were created to describe participants' experiences: (1) compensation for other internalised stigma, (2) to suppress body parts that can be gendered or sexualised, (3) comparisons to romantic partners' bodies, (4) media representations, (5) queer signalling, (6) queerness as protective, (7) gender expression and dysphoria, (8) societal expectations of women's bodies, and (9) internalisation of body/beauty ideals. Seven sub-themes were created to represent beauty ideals for specific subcultural communities (e.g. femme, butch). Findings suggest that queer women attribute individual, interpersonal and social factors to weight concerns, behaviours and perceptions. Findings highlight how complex tensions between the beauty/body ideals experienced in cisheteronormative and queer spaces influence eating and weight concerns among queer women. Gender, sexual orientation and subcultural ideals intersect in important ways, and may be useful to consider when screening, treating and preventing eating and weight concerns among queer women.

Background: The Avoidant Restrictive Food Intake Disorder - Genes and Environment (ARFID-GEN) study is a study of genetic and environmental factors that contribute to risk for developing ARFID in children and adults., Methods: A total of 3,000 children and adults with ARFID from the United States will be included. Parents/guardians and their children with ARFID (ages 7 to 17) and adults with ARFID (ages 18 +) will complete comprehensive online consent, parent verification of child assent (when applicable), and phenotyping. Enrolled participants with ARFID will submit a saliva sample for genotyping. A genome-wide association study of ARFID will be conducted., Discussion: ARFID-GEN, a large-scale genetic study of ARFID, is designed to rapidly advance the study of the genetics of eating disorders. We will explicate the genetic architecture of ARFID relative to other eating disorders and to other psychiatric, neurodevelopmental, and metabolic disorders and traits. Our goal is for ARFID to deliver "actionable" findings that can be transformed into clinically meaningful insights., Trial Registration: ARFID-GEN is a registered clinical trial: clinicaltrials.gov NCT05605067., (© 2023.

Purpose: To examine differences in elevated eating disorder risk and self-reported eating disorder diagnosis across subgroups of transgender and gender diverse (TGD) college students., Methods: Data from 5057 TGD college students participating in the national Healthy Minds Study between 2014 and 2019 were analyzed. Chi-square tests and logistic regression analyses examined heterogeneity in prevalence and odds of elevated eating disorder risk, as measured by the SCOFF, and self-reported eating disorder diagnosis by gender, as well as by intersecting gender and sexual orientation identities., Results: Genderqueer and/or non-conforming college students reported the highest prevalence of elevated eating disorder risk (38.8%) relative to gender expansive students. Genderqueer and/or non-conforming (11.1%), gender expansive (12.3%), and trans men and/or transmasculine students (10.5%) reported higher prevalence of a self-reported eating disorder diagnosis relative to trans women and/or transfeminine students (6.3%). Heterosexual or straight trans men had lower odds of eating disorder risk and self-reported diagnosis relative to trans men with a minoritized sexual orientation., Conclusions: Genderqueer and/or non-conforming college students may be at heightened eating disorder risk. Moreover, a heterosexual and/or straight sexual orientation was associated with lower odds of elevated eating disorder risk and self-reported eating disorder diagnoses among trans men and genderqueer and/or non-conforming college students, but this finding did not hold for other groups. College campuses should aim to reduce eating disorder risk among TGD students., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Individuals with eating disorders (EDs) are at significant risk for increases in symptomatology and diminished treatment access during the COVID-19 pandemic. Environmental precautions to limit coronavirus spread have affected food availability and access to healthy coping mechanisms, and have contributed to weight-stigmatizing social media messages that may be uniquely harmful to those experiencing EDs. Additionally, changes in socialization and routine, stress, and experiences of trauma that are being experienced globally may be particularly deleterious to ED risk and recovery. This paper presents a brief review of the pertinent literature related to the risk of EDs in the context of COVID-19 and offers suggestions for modifying intervention efforts to accommodate the unique challenges individuals with EDs and providers may be experiencing in light of the ongoing public health crisis.

This study examined whether exposure to weight discrimination modified the association between sexual orientation, self-reported eating disorders, self-reported depression and academic impairment in a large sample of college students. Participants (n = 13,782) were from the 2015-2018 College Student Health Survey. Logistic regressions tested whether weight discrimination magnified psychological health concerns and academic impairment in sexual minority students (i.e., lesbian, gay) relative to their heterosexual peers and were stratified by gender (cisgender men and cisgender women). Sexual minority men and women reported more weight discrimination, eating disorders, depression, and academic impairment than their heterosexual peers, even after controlling for BMI and race. Among sexual minority men and women, weight discrimination was associated with increased eating disorders and academic impairment, but not depression. Weight discrimination increased the rate of eating disorders, depression, and academic impairment, however, the rate was still higher among sexual minority students regardless of weight discrimination status or gender. College-based interventions should aim to reduce weight stigmatization and its associated influence on psychological health and academic functioning, and address the needs of sexual minority college students, as they may be at highest risk. Clinicians should work to reduce the harms of weight discrimination, particularly in sexual minority young adults.

Objective: Although current treatments are effective for some patients with eating disorders, a large number of patients remain partially or fully symptomatic post-treatment. This may be related to poor utilization of treatment skills outside of the therapy office. Smartphone applications that can detect and intervene during moments of need could facilitate such skill use between sessions., Method: Individuals (N = 16) participated in a small pilot open trial where they received 21 sessions of in-person Integrative Cognitive-Affective Therapy (ICAT) therapy an app (iCAT+) that delivers ecological momentary interventions (EMI) in response to user-entered data. Data were collected on the feasibility and acceptability of this treatment approach and on preliminary indicators of treatment outcomes., Results: Participants found iCAT+ as a treatment augmentation acceptable and indicated it had clinical utility as an adjunct to in-person therapy, although analyses indicated poor compliance with data entry needed to trigger EMI delivery. This suggests that long-term use of EMI requiring ongoing data entry is infeasible., Conclusions: We describe lessons learned from our initial pilot trial and future directions for the development of impactful EMI systems that can be used to augment in-person therapies., (© 2020 Eating Disorders Association and John Wiley & Sons Ltd.)

People with eating disorders (ED) have elevated rates of suicidal thoughts and behaviors. We used network analysis to identify symptoms that bridge EDs and suicidality, as well as central symptoms within the network, among 3 groups of adults. Participants were either (a) clinical psychiatric outpatients without current EDs ( n = 538), (b) clinical psychiatric outpatients with a lifetime suicide attempt ( n = 166), or (c) people with current EDs ( n = 238). Networks were jointly estimated among groups. Within the Suicide Attempt and ED groups, interoceptive deficits and pain tolerance emerged as important bridge symptoms, whereas feeling inadequate was an important bridge symptom in the Clinical Outpatient group. Within all groups, having thoughts of killing oneself and feeling inadequate were central, meaning that they were most strongly connected to all other symptoms in the networks. Further, results indicate that a similar problem-interoceptive impairment-may link ED symptoms and suicidality both within people with EDs and people with suicide attempts. Overall, these findings are consistent with the notion that EDs and suicidality may bidirectionally influence one another, possibly through shared mechanisms (e.g., interoceptive impairment) or direct pathways (e.g., suicidal ideation being strongly connected to ED symptoms), though prospective work is needed to test these possibilities.

Objective: The purpose of the current study was threefold: (a) compare rates of self-reported anorexia nervosa (AN), self-reported bulimia nervosa (BN), and eating pathology-specific academic impairment (EAI) by gender identity (cisgender men, cisgender women, transgender or genderqueer) and sexual orientation (gay or lesbian, bisexual, unsure, other), (b) examine associations between gender identity, sexual orientation, and eating outcomes, and (c) identify for whom rates of eating disorder diagnosis and impairment is greatest., Method: The study includes a sample of Minnesota students (n = 13,906) who participated in the College Student Health Survey from 2015 to 2018. Chi-square tests with bootstrapping examined differences in eating pathology rates between groups. Adjusted logistic regressions tested the association between gender identity, sexual orientation, and self-reported eating outcomes., Results: Chi-square results revealed heightened rates of self-reported AN, self-reported BN, and EAI in cisgender women, transgender or genderqueer, and sexual minority (e.g., lesbian or bisexual) students. Logistic regression analyses in cisgender men and cisgender women revealed higher odds of self-reported AN, self-reported BN, and EAI in sexual minority students relative their heterosexual peers. Chi-square analyses indicated that bisexual cisgender women reported heightened rates of all three eating pathology measures relative to other sexual and/or gender (e.g., transgender) minority students., Discussion: Individuals with marginalized gender and/or sexual orientation identities report heightened rates of eating pathology, with cisgender bisexual women reporting the poorest outcomes relative to individuals from other marginalized identities. Preventive efforts and more research are needed to understand the mechanisms driving this disparity and to reduce prevalence among marginalized groups., (© 2020 Wiley Periodicals, Inc.)

The authors present the theoretic model, structure of treatment, and preliminary evidence for several emerging treatments that are increasingly being used and studied in eating disorders treatment, including dialectical behavior therapy, acceptance and commitment therapy, integrative cognitive-affective therapy, and neuromodulation. In addition, the article discusses treatments that address mindfulness, interpersonal factors, and habit., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Disordered eating frequently co-occurs with nonsuicidal self-injury (NSSI), and evidence suggests that the co-occurrence of these behaviors is associated with heightened emotion dysregulation. However, little is known about the relationship between restrictive eating and NSSI, and the significance of their co-occurrence. This study examined cross-sectional associations between self-reported restrictive eating, NSSI, and putative mechanisms of emotion regulation and interpersonal problems in a non-clinical sample of undergraduate students (N = 98, 80.6% female), using the Dietary Restriction Screener (Haynos & Fruzzetti, 2015), Deliberate Self-Harm Inventory (Gratz, 2001), Difficulties in Emotion Regulation Scale (Gratz & Roemer, 2006), and Inventory of Interpersonal Problems-Personality Disorders-25 (Kim & Pilkonis, 1999). Hierarchical logistic regression analyses indicated that restrictive eating was associated with NSSI above and beyond the influence of binge eating, purging, and relevant covariates (B = 2.04, p < 0.001). In addition, multivariate analyses of variance revealed that the co-occurrence of restrictive eating and NSSI was associated with greater difficulties accessing and implementing effective, rather than impulsive, emotion regulation strategies when distressed than either behavior alone (p < 0.001). Findings highlight the seriousness of restrictive eating even within a nonclinical sample, as it is associated with heightened probability of NSSI and clinical severity among those who engage in co-morbid NSSI. Healthcare providers are encouraged to screen for NSSI among individuals with restrictive eating. In addition, a focus on improving emotion regulation and interpersonal skills may enhance prevention and intervention efforts for individuals with co-occurring restrictive eating and NSSI behaviors., (Copyright © 2018.

This study examined the prevalence of reported suicide attempts among family members of individuals with an eating disorder (ED). 1870 individuals presenting for ED treatment reported whether their family members ever made a suicide attempt using the Eating Disorders Questionnaire. A lifetime suicide attempt by any family member was reported by 10.8% (n = 202) of the sample and ranged from 7.0% of those with eating disorder not otherwise specified to 16.1% of those with purging disorder. Controlling for age and gender, individuals with bulimia nervosa had a higher prevalence of any familial suicide attempt and mother suicide attempt than individuals with EDNOS; no other differences were observed across ED diagnoses. There were no differences in prevalence of reported suicide attempts made by fathers, brothers, sisters, uncles, or aunts by ED diagnosis. Findings support a growing literature indicating a familial association between EDs and suicide risk., (© 2017 Wiley Periodicals, Inc.)

Objective: The Interpersonal Theory of Suicide (IPTS) model has not been fully tested in a clinical eating disorder (ED) population., Method: Participants (N = 114) completed questionnaires assessing suicidal ideation (SI), suicide attempts (SA), and constructs of the IPTS. Logistic regressions determined whether thwarted belongingness and perceived burdensomeness were associated with lifetime SI. Among those who endorsed lifetime SI, logistic regressions were used to determine whether elements of the acquired capability for suicide (fearlessness about death and painful and provocative events) were associated with lifetime SA., Results: Sixty-five participants (57.0%) had lifetime SI and 24 (21.1%) had lifetime SA. Thwarted belongingness (P < 0.001) and perceived burdensomeness (P < 0.01) were associated with lifetime SI. Painful and provocative events were associated with lifetime SA (P < 0.03)., Discussion: The IPTS was partially supported. Targeting interpersonal variables may be important in treating and preventing suicidality. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:162-165)., (© 2016 Wiley Periodicals, Inc.)

Background: This study examined the associations between specific dimensions of emotion dysregulation and eating disorder (ED) symptoms and behaviors, non-suicidal self-injury (NSSI), and suicide attempts in a heterogeneous ED sample., Methods: Participants (N=110) completed the Difficulties in Emotion Regulation Scale (DERS), the Eating Disorder Examination Questionnaire (EDE-Q), and self-reported the presence of lifetime NSSI and a lifetime suicide attempt., Results: The EDE-Q global score, a primarily cognitive measure of ED symptoms, was significantly positively correlated with DERS strategies, clarity, and awareness subscale scores and DERS total score (ps<0.01). Only the strategies subscale was uniquely positively associated with EDE-Q global score in a multivariate regression analysis. There was no association between the frequency of binge eating or frequency of driven exercise and any of the DERS subscale scores or total score (ps>0.01). Frequency of purging was significantly, positively associated with DERS impulse subscale score and total score (p<0.01). None of the DERS subscale scores were significantly different between those with and without NSSI or between those with and without a lifetime suicide attempt (ps>0.01)., Conclusions: Findings indicate that in a heterogeneous ED sample, emotion regulation deficits are more strongly associated with cognitively-oriented symptoms of EDs than behavioral symptoms such as a binge eating, purging, driven exercise, NSSI, or suicide attempts., (Copyright © 2016 Elsevier Inc.

Objective: To describe the frequency of self-weighing and reactions to prescribed weekly weighing among individuals with eating disorder (ED) diagnoses, and to compare individuals weighing more or less frequently on mass index (BMI) and the Eating Disorder Examination (EDE) subscales., Method: Baseline EDE and demographics from five studies (N = 758)., Results: Self-weighing was most frequent among individuals with anorexia nervosa (AN), followed by those with bulimia nervosa (BN) and binge eating disorder (BED). On average, participants reacted moderately negative to prescribed weekly weighing. No relationship between weighing frequency and BMI was evident in any sample. There was indication of greater pathology (i.e., restraint, shape concern, weight concern, global) in AN with more frequent weighing. In BN, mixed evidence emerged to support a relationship between more frequent weighing and higher shape concern, weight concern, and global score. In BED, higher restraint was found in those who weighed versus those who did not., Discussion: Weighing frequency in each eating disorder (ED) sample was to some extent associated with greater ED severity, but not BMI. Future research should examine relationships between self-weighing, reactions to changing weighing frequency, and ED symptomatology in both ED and non-ED groups to understand the impact of self-weighing in heterogeneous populations. © 2016 Wiley Periodicals, Inc.

Currently, research support is strongest for family-based treatment (FBT) for the treatment of anorexia nervosa (AN) in adolescents. However, a strong evidence base for treatments for older adolescents and young adults with AN is lacking. Emphasizing social support in the treatment of AN may be beneficial for older adolescents and young adults with AN. This paper provides a brief review of the literature on FBT for adolescent AN and provides a case example of adolescent AN treated with FBT. We then discuss novel treatments that have incorporated social support for older adolescents and young adults with AN, such as modified FBT and couples-based interventions. We provide case studies of each of these novel treatment approaches as well. Additionally, this paper highlights and discusses developmental considerations and challenges in working with older adolescents and young adults with AN.

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.

The current study examined the association between affect and self-reported alcohol intoxication in women with bulimia nervosa (BN; N=133). Participants completed a two-week ecological momentary assessment protocol. Momentary global positive affect (PA) and negative affect (NA), as well as the facets of NA (fear, guilt, hostility and sadness), were measured. Forty-five participants endorsed that they "got drunk" during the study period. Daily mean and variability of global PA and NA were compared between days with self-reported alcohol intoxication and days without self-reported alcohol intoxication. Trajectories of affect were modeled prior to and following episodes of self-reported alcohol intoxication. There were no differences in the mean or variability of PA or NA on days characterized by self-reported alcohol intoxication compared to days with no self-reported alcohol intoxication (ps>0.05). PA decreased significantly prior to self-reported alcohol intoxication and remained stable afterwards. There were no changes in global NA before or after self-reported alcohol intoxication, but an examination of the facets of NA showed that sadness increased following episodes of self-reported alcohol intoxication. These findings showed only partial support for a negative reinforcement model of alcohol use in women with BN., (Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.)

Purpose: The purpose of this study was to explore the association between specific forms of childhood abuse and neglect with lifetime suicide attempts in women with bulimia nervosa (BN)., Methods: Two hundred and four women aged 18-65 (mean 25.6 years, SD 9.13) with full or subclinical BN were recruited in five US Midwestern communities and specialized eating disorder clinics. Participants completed questionnaires including the Childhood Trauma Questionnaire (CTQ) and self-reported whether they had ever had a lifetime suicide attempt. Logistic regression analyses were used to predict lifetime suicide attempts from each subscale of the CTQ., Results: Childhood emotional, physical, and sexual abuse were significantly associated with the presence of a lifetime suicide attempt in women with BN. Childhood emotional and physical neglect were not associated with suicide attempts., Conclusions: Individuals with BN who have experienced childhood emotional and sexual abuse are at increased risk of a lifetime suicide attempt. Future research is needed to understand the mechanism to address in treatment and prevention efforts. It is important for clinicians to be aware of the potential increased risk of suicide in individuals with BN with a history of childhood abuse.

Objective: The purpose of this investigation was to examine whether narrowing the criteria of anorexia nervosa (AN) subtypes among adults based on further delineations of current binge eating and purging (i.e., binge eating only, purging only, binge eating and purging, and restricting only) improves the potential clinical utility of the current DSM-5 system that specifies two types (i.e., current binge eating and/or purging and restricting, specified as the absence of current binge eating and/or purging)., Method: Self-reported eating disorder and psychiatric symptoms based on the Eating Disorder Questionnaire were examined in 347 adults from a multisite clinical sample who met DSM-IV criteria for AN. Classification based on binge eating and purging symptoms yielded the following subtypes: 118 restricting only (AN-R; no current binge eating or purging); 133 binge eating and purging (AN-B & P; current binge eating and purging); 43 binge eating only (AN-B; current binge eating and no current purging); and 53 purging only (AN-P; current purging and no current binge eating)., Results: The AN-R group had lower current body mass index compared to AN-B & P and AN-P with no group differences in highest, lowest, or desired body mass index. The probability of amenorrhea was higher for the AN-R and AN-B & P groups than the AN-P group. The probability of diet pill use was elevated for the AN-B & P and AN-P groups compared to the AN-R group. The AN-P group also had a higher probability of fasting than the AN-R group. The probability of substance use including tobacco was lower in the AN-R group than the other three groups. No group differences were found on measures of hospitalization, body image, physical symptoms, exercise, or dieting behaviors., Conclusions: These findings do not support the validity or clinical utility of classifying AN into narrower subtypes based on current binge eating, purging, and binge eating with purging given that few differences were found among groups who reported any combination of current binge eating and purging. Future research is needed to replicate these findings and to further examine the AN subtype classification schemes., (Copyright © 2016 Elsevier Inc. All rights reserved.)

The development of eating pathology is a concern following bariatric surgery, even in the absence of any pre-surgical psychopathology. No consistent risk factors have emerged in the literature to identify those at greatest risk. However, post-surgical guidelines encourage eating behaviors that would be considered disordered in other contexts. We present a case of an adolescent developing bulimia nervosa following gastric bypass surgery and the escalation of her symptoms from diligently following recommended food behaviors to a full-syndrome clinical eating disorder. We discuss the differences between appropriate post-surgical eating behaviors and disordered eating behaviors. We provide recommendations for clinicians to screen for eating pathology and referrals to an interprofessional treatment team to address eating disordered behaviors and cognitions.

Objective: The relative importance of loss of control and overeating in the relationship between binge eating and eating-related and general psychopathology has been debated in the literature. This study assessed the prevalence and correlates of overeating with and without loss of control within a diverse, population-based sample of adolescents., Method: A highly diverse (81.1% non-White) sample of adolescents (n = 2,793) from EAT-2010 (Eating and Activity in Teens) completed self-report questionnaires assessing eating-related psychopathology, substance use, nonsuicidal self-injury, depressive symptoms, and self-esteem., Results: Overeating without loss of control was reported by 6.9% of girls and 5.0% of boys, while 9.6% of girls and 6.3% of boys reported overeating with loss of control (binge eating). Overall, overeating (with or without loss of control) was positively associated with unhealthy or extreme weight control behaviors, dieting, nonsuicidal self-injury, lower body satisfaction, and self-esteem, and higher depressive symptoms relative to no overeating. Among girls, binge eating was associated with unhealthy or extreme weight control behaviors, lower self-esteem, and higher depressive symptoms relative to overeating without loss of control, while in boys, binge eating was associated with greater cigarette usage, lower body satisfaction, and greater depressive symptoms than overeating without loss of control (although cigarette usage was comparable in boys reporting binge eating and no overeating)., Discussion: Any overeating, with or without loss of control, was associated with multiple adverse correlates among adolescents. Loss of control was uniquely associated with multiple health indicators, further highlighting its importance as a marker of severity of overeating., (© 2015 Wiley Periodicals, Inc.)

Objective: This study examined negative and positive affect in relation to restrictive eating episodes (i.e., meals/snacks perceived as restrictive) and whether restrictive eating was associated with likelihood of subsequent eating disorder behaviors (i.e., additional restrictive eating, binge eating, vomiting, laxative use, weighing, exercising, meal skipping, drinking fluids to curb appetite, body checking)., Method: Women with anorexia nervosa (N = 118) completed a 2-week ecological momentary assessment protocol., Results: For both restrictive and nonrestrictive eating, negative affect significantly increased from prebehavior to the time of the behavior but remained stable thereafter, while positive affect remained stable from prebehavior to the time of the behavior but decreased significantly thereafter. Across time, negative affect was significantly lower and positive affect was significantly greater in restrictive than nonrestrictive episodes. Engagement in restrictive eating was associated with an increased likelihood of subsequent restrictive eating, laxative use, and body checking, but not other behaviors. Engagement in nonrestrictive eating was associated with a decreased likelihood of subsequent restrictive eating, binge eating, vomiting, laxative use, weighing, meal skipping, drinking fluids to curb appetite, and body checking., Discussion: Despite similar patterns of affect across eating episodes over time, results suggest affect may be involved in the maintenance of restrictive eating in anorexia nervosa since restrictive episodes were associated with lower negative and greater positive affect across time compared to nonrestrictive episodes. Further, while restrictive episodes increased the likelihood of only three subsequent eating disorder behaviors, nonrestrictive episodes were protective since they decreased likelihood of all but one behavior., (© 2015 Wiley Periodicals, Inc.)

Objective: The objective of this study was to identify personality traits and psychiatric comorbidities associated with a lifetime history of a suicide attempt in women with bulimia nervosa (BN)., Method: Data from two samples of women with BN (n = 204 and n = 133) were examined. Participants in both samples completed the Dimensional Assessment of Personality Pathology-Basic Questionnaire and reported whether they had ever had a lifetime suicide attempt. Comorbid psychopathology was based on self-reported questionnaire and interview data. Univariate and multivariate logistic regression analyses were run, predicting a lifetime suicide attempt., Results: Based on the Dimensional Assessment of Personality Pathology-Basic Questionnaire, identity problems were associated with a lifetime suicide attempt in both samples; cognitive dysregulation, anxiousness and insecure attachment were associated with a lifetime suicide attempt in one but not both samples. Lifetime anxiety disorder was associated with a lifetime suicide attempt in one sample, and depression was associated with a lifetime suicide attempt in both samples. Multivariate analyses revealed that only depression was uniquely associated with a lifetime suicide attempt in both samples., Discussion: Although personality traits associated with aspects of emotion dysregulation were associated with a lifetime suicide attempt, depression was found to have the strongest association with a lifetime suicide attempt in two samples of women with BN. These findings suggest that depression severity may be the most important target of treatment and suicide prevention efforts in women with BN., (Copyright © 2015 John Wiley & Sons, Ltd and Eating Disorders Association.)

Accumulating evidence suggests that bariatric surgery candidates are likely to present with eating disorders (EDs) and/or problematic eating behaviours (EBs), and research suggests that these problems may persist or develop after bariatric surgery. While there is growing evidence indicating that EDs and EBs may impact bariatric surgery outcomes, the definitions and assessment methods used lack consensus, and findings have been mixed. The aims of this paper were (1) to summarize the existing literature on pre-operative and post-operative EDs and problematic EBs; (2) to discuss the terms, definitions and assessment measures used across studies; and (3) to consider the extent to which the presence of these problems impact surgery outcomes. We highlight the importance of investigators utilizing consistent definitions and assessment methodologies across studies., (© 2015 The Authors.

This study examined whether perceptions of group dynamics early in treatment predicted eating disorder outcomes in a sample of adults (N = 190) with binge eating disorder (BED) who participated in a 15-session group cognitive behavior therapy (gCBT) treatment with differing levels of therapist involvement (therapist led, therapist assisted, and self-help). The group dynamic variables included the Engaged subscale of the Group Climate Questionnaire--Short Form and the Group Attitude Scale, measured at session 2 and session 6. Treatment outcome was assessed in terms of global eating disorder severity and frequency of binge eating at end of treatment, 6-month, and 12-month follow-up. Session 2 engagement and group attitudes were associated with improved outcome at 12-month follow-up. No other group dynamic variables were significantly associated with treatment outcome. Group dynamic variables did not differ by levels of therapist involvement. Results indicate that early engagement and attitudes may be predictive of improved eating disorder psychopathology at 12 month follow-up. However, the pattern of mostly insignificant findings indicates that in gCBT, group process variables may be less influential on outcomes relative to other treatment components. Additionally, participants were able to engage in group treatment regardless of level of therapist involvement., (Copyright © 2015 Elsevier Ltd. All rights reserved.)

This study investigated the importance of the distinction between objective (OBE) and subjective binge eating (SBE) among 80 treatment-seeking adolescents with bulimia nervosa. We explored relationships among OBEs, SBEs, eating disorder (ED) symptomatology, depression, and self-esteem using two approaches. Group comparisons showed that OBE and SBE groups did not differ on ED symptoms or self-esteem; however, the SBE group had significantly greater depression. Examining continuous variables, OBEs (not SBEs) accounted for significant unique variance in global ED pathology, vomiting, and self-esteem. SBEs (not OBEs) accounted for significant unique variance in restraint and depression. Both OBEs and SBEs accounted for significant unique variance in eating concern; neither accounted for unique variance in weight/shape concern, laxative use, diuretic use, or driven exercise. Loss of control, rather than amount of food, may be most important in defining binge eating. Additionally, OBEs may indicate broader ED pathology, while SBEs may indicate restrictive/depressive symptomatology., (Copyright © 2014 John Wiley & Sons, Ltd and Eating Disorders Association.)

Objective: Using a prospective design, to examine the relation between self-image (assessed using the Structural Analysis of Social Behavior) and suicide attempts/completions in women with anorexia nervosa-restricting type (ANR), anorexia nervosa-binge/purge type (ANBP), bulimia nervosa (BN), binge eating disorder (BED), and eating disorder not otherwise specified (EDNOS); and to assess whether these self-image variables add unique predictive value to suicide when considering other baseline predictors., Method: Women (N=2269) aged 12 to 45 (M=22.1) presenting to specialist eating disorders clinics in Sweden between 2005 and 2009 were identified through the Stepwise Eating Disorders Quality Register. Data on age, body mass index, eating disorder severity (Eating Disorder Examination-Questionnaire scores), psychiatric comorbidity, global assessment of functioning, and self-image were abstracted from Stepwise and included as baseline predictors or covariates. Suicide information (prior attempt and attempt/completion after Stepwise registration) was obtained from the National Patient Register and Cause of Death Register., Results: Prevalence of detected suicide attempts/completions over the study period was 9.2%. Negative self-image variables were associated with prior suicide attempts in ANR and EDNOS and later suicide attempts/completions in women with BN. In a stepwise Cox proportional hazards model, only low self-affirmation predicted time to suicide attempts/completions in women with BN when accounting for age and prior suicide attempt., Conclusion: Assessing self-image might assist with identifying women with BN at elevated risk for suicide., (Copyright © 2014 Elsevier Inc.

Objective: To describe the treatment development and pilot testing of a group parenting intervention, NURTURE (Networking, Uniting, and Reaching out To Upgrade Relationships and Eating), for mothers with histories of eating disorders., Method: Based on focus group findings, extant research, and expert opinion, NURTURE was designed to be delivered weekly over 16 (1.5 h) sessions via an interactive web conferencing forum. It comprises four modules: (1) laying the foundation, (2) general parenting skills, (3) eating and feeding, and (4) breaking the cycle of risk. Pilot testing was conducted with three groups of 3-6 mothers (N = 13) who had children ages 0-3 years to determine feasibility (e.g., retention), acceptability (e.g., feedback questionnaire responses), and preliminary efficacy. Maternal satisfaction with NURTURE and changes in mother-child feeding relationship measures, maternal feeding style, maternal self-efficacy, and maternal psychopathology (eating disorder, depression, and anxiety symptoms) across three time points (baseline, post-treatment, 6-month follow-up) were examined. All outcomes were exploratory., Results: The intervention was well tolerated with a 100% retention rate. Feedback from mothers was generally positive and indicated that the groups provided an engaging, supportive experience to participants. We observed changes suggestive of improvement in self-reported maternal self-efficacy and competence with parenting. There were no notable changes in measures of maternal feeding style or psychopathology., Discussion: NURTURE is a feasible, acceptable, and potentially valuable intervention for mothers with eating disorder histories. Results of this pilot will inform a larger randomized-controlled intervention to determine efficacy and impact on child outcomes., (Copyright © 2013 Wiley Periodicals, Inc.)

We evaluated whether the prevalence of lifetime suicide attempts/completions was higher in women with a lifetime history of an eating disorder than in women with no eating disorder and assessed whether eating disorder features, comorbid psychopathology, and personality characteristics were associated with suicide attempts in women with anorexia nervosa, restricting subtype (ANR), anorexia nervosa, binge-purge subtype (ANBP), lifetime history of both anorexia nervosa and bulimia nervosa (ANBN), bulimia nervosa (BN), binge eating disorder (BED), and purging disorder (PD). Participants were part of the Swedish Twin study of Adults: Genes and Environment (N = 13,035) cohort. Lifetime suicide attempts were identified using diagnoses from the Swedish National Patient and Cause of Death Registers. General linear models were applied to evaluate whether eating disorder category (ANR, ANBP, ANBN, BN, BED, PD, or no eating disorder [no ED]) was associated with suicide attempts and to identify factors associated with suicide attempts. Relative to women with no ED, lifetime suicide attempts were significantly more common in women with all types of eating disorder. None of the eating disorder features or personality variables was significantly associated with suicide attempts. In the ANBP and ANBN groups, the prevalence of comorbid psychiatric conditions was higher in individuals with than without a lifetime suicide attempt. The odds of suicide were highest in presentations that included purging behavior (ANBN, ANBN, BN, and PD), but were elevated in all eating disorders. To improve outcomes and decrease mortality, it is critical to be vigilant for suicide and identify indices for those who are at greatest risk., (PsycINFO Database Record (c) 2013 APA, all rights reserved.)

Objective: These three studies examined the hypothesis that prenatal exposure to sex hormones influences twins' risk for eating disorders based on co-twin sex, such that individuals with a female co-twin would be more likely than individuals with a male co-twin to meet diagnostic criteria for an eating disorder., Methods: Male and female twins from the United States (N=2607), Norway (N=2796) and Sweden (N=16,458) with known co-twin sex and zygosity were assessed for eating disorders., Results: In the U.S. and Swedish samples, sex was significantly associated with eating disorder diagnoses, and although co-twin sex was not associated with eating disorders overall, it was associated with broadly defined bulimia nervosa in the Swedish sample. The effects for bulimia were not sustained when monozygotic twins were excluded, suggesting that the effects of prenatal sex hormones play a minor role in influencing eating disorders. Sex and co-twin sex were not associated with eating disorders in the Norwegian sample., Conclusion: The prenatal sex hormone hypothesis, which proposes that prenatal hormone exposure is associated with later eating disorder symptomatology, was not supported in these three population-based twin samples., (Copyright © 2011 Elsevier Inc.

Background: Little is known about the association of eating disorder subtypes across multiple categories of substance use in population-based samples. We examined the association between eating disorders and substance use in a large population-based sample., Method: Female participants (n=13 297) were from the Swedish Twin Registry [Lichtenstein et al., Twin Research and Human Genetics (2006) 9, 875-882]. Substance use was examined in four defined groups - (1) anorexia nervosa (AN); (2) bulimia nervosa (BN); (3) AN and BN (ANBN); and (4) binge eating disorder (BED) as well as a referent group without eating disorder (no ED). Secondary analyses examined differences between restricting AN (RAN) and binge and/or purge AN (ANBP)., Results: In general, eating disorders were associated with greater substance use relative to the referent. The AN group had significantly increased odds for all illicit drugs. Significant differences emerged across the RAN and ANBP groups for alcohol abuse/dependence, diet pills, stimulants, and polysubstance use with greater use in the ANBP group. Across eating disorder groups, (1) the BN and ANBN groups were more likely to report alcohol abuse/dependence relative to the AN group, (2) the ANBN group was more likely to report diet pill use relative to the AN, BN and BED groups, and (3) the BN group was more likely to report diet pill use relative to the no ED, AN and BED groups., Conclusions: Eating disorders are associated with a range of substance use behaviors. Improved understanding of how they mutually influence risk could enhance understanding of etiology and prevention.

Background: We present a bivariate twin analysis of anorexia nervosa and bulimia nervosa to determine the extent to which shared genetic and environmental factors contribute to liability to these disorders., Method: Focusing on females from the Swedish Twin study of Adults: Genes and Environment (n = 7000), we calculated heritability estimates for narrow and broad anorexia nervosa and bulimia nervosa and estimated their genetic correlation., Results: In the full model, the heritability estimate for narrow anorexia nervosa (AN) was (a(2) = .57; 95% confidence interval [CI]: .00-.81) and for narrow bulimia nervosa (BN) (a(2) = .62; 95% CI: .08-.70), with the remaining variance accounted for by unique environmental factors. Shared environmental factors estimates were (c(2) = .00; 95% CI: .00-.67) for AN and (c(2) = .00; 95% CI: .00-.40) for BN. Moderate additive genetic (.46) and unique environmental (.42) correlations between AN and BN were observed. Heritability estimates for broad AN were lower (a(2) = .29; 95% CI: .04-.43) than for narrow AN, but estimates for broad BN were similar to narrow BN. The genetic correlation for broad AN and BN was .79, and the unique environmental correlation was .44., Conclusions: We highlight the contribution of additive genetic factors to both narrow and broad AN and BN and demonstrate a moderate overlap of both genetic and unique environmental factors that influence the two conditions. Common concurrent and sequential comorbidity of AN and BN can in part be accounted for by shared genetic and environmental influences on liability although independent factors also operative.

Objective: Critical first steps in the treatment of anorexia nervosa (AN) include re-nutrition and weight restoration, both highly anxiety provoking for patients. We explored the impact of progressive muscle relaxation (PMR), guided imagery (GI), self-directed relaxation (SR), and control (C) on reducing postprandial anxiety in 64 females with AN., Method: Participants began the study upon hospital admission. They received relaxation training after lunch for 15 days. Pre- and post-session anxiety and treatment acceptability ratings were made daily., Results: Although all conditions improved relaxation and decreased anxiety, feelings of fullness, and thoughts about weight, the three active conditions significantly reduced anxiety and increased relaxation more than C (p < .0001). Participants significantly enjoyed the three active treatments, were more likely to recommend them to a friend, and were more likely to use either PMR or GI again versus C (p < .0001)., Conclusion: Relaxation may be a valuable component for reducing postprandial anxiety in AN., ((c) 2008 by Wiley Periodicals, Inc.)

Objective: To examine the association between disordered eating (fasting, diet product use, and vomiting or laxative use) and use of 10 substances (cigarettes, alcohol, marijuana, cocaine, inhalants, heroin, methamphetamines, ecstasy, steroids, and hallucinogens) in a nationally representative adolescent sample., Method: Participants were 13,917 U.S. high-school students participating in the 2005 Youth Risk Behavior Surveillance System., Results: Disordered eating was significantly associated with the use of each substance. Using effect size estimates that take base rates into consideration, for female students, associations between substance use and disordered eating were weak for all but three forms of substance use: current smoking, binge drinking, and inhalants. Among male students, strong (marijuana, steroids, and inhalants) or moderate effects (all other substances) were observed., Conclusion: Future research needs to focus on inhalant use and methamphetamine use in males. Increased medical attention should be directed toward adolescents who practice disordered eating behaviors because they are also at elevated risk for using cigarettes, alcohol, inhalants, methamphetamines, and steroids., ((c) 2008 by Wiley Periodicals, Inc.)

Objective: To examine trends in weight control practices from 1995 to 2005., Method: The Youth Risk Behavior Surveillance System biennially assesses five weight control behaviors among nationally representative samples of United States high school students., Results: Across time, more females than males dieted (53.8% vs. 23.8%), used diet products (10% vs. 4.3%), purged (7.5% vs. 2.7%), exercised (66.5% vs. 46.9%), or vigorously exercised (42.8% vs. 36.8%). All weight control behaviors among males increased during the decade. Black females were less likely than Hispanic females, who were less likely than White females, to practice weight control. White males were less likely than Black males, who were less likely than Hispanic males, to practice weight control. The ethnic difference in weight control practices is consistent across time., Conclusion: All male adolescents are at increasing risk for developing eating disorder symptomatology, and Black females appear to continue to resist pressure to pursue thinness.
