Direct, indirect, and reciprocal associations between perfectionism, compulsive exercise and eating disorder pathology in adolescents with eating disorders.

BACKGROUND: There is a strong association between perfectionism and eating disorders. In a cognitive-behavioural model of compulsive exercise it has been suggested there are reciprocal associations between perfectionism, eating disorder pathology, and compulsive exercise. No study has examined if there is an indirect association between perfectionism and compulsive exercise through eating disorder pathology, which would inform a preliminary understanding of the cognitive-behavioural model of compulsive exercise. METHODS: The sample included 301 adolescent females diagnosed with eating disorders (age M = 14.89, SD = 0.85, range 13-17). We tested models of direct and indirect associations of compulsive exercise in the relationship between perfectionism and eating disorder pathology, and direct and indirect associations of eating disorder pathology in the relationship between compulsive exercise and perfectionism. RESULTS: Perfectionism was directly associated with eating disorder pathology and compulsive exercise. Perfectionism was indirectly associated with eating disorder pathology through compulsive exercise. Perfectionism also had an indirect association with compulsive exercise through eating disorder pathology. DISCUSSION: The findings suggest it would be useful for future prospective research to examine the cognitive-behavioural model of compulsive exercise in adolescents with eating disorders. Compulsive exercise and perfectionism may be useful targets for future research to improve eating disorder treatment. Level of evidence Level V: Opinions of respected authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

Course and predictors of eating disorder symptoms, anxiety symptoms, and pandemic-related eating disorder concerns among adults with eating disorders during the first year of the COVID-19 pandemic.

OBJECTIVE: The COVID-19 pandemic and public health mitigation measures have negatively impacted individuals with eating disorders (ED). We evaluated changes in and predictors of ED symptoms, pandemic-related ED concerns, and anxiety symptoms across the first 12 months of the COVID-19 pandemic among individuals with self-reported EDs in the United States (US), Sweden (SE), and the Netherlands (NL). METHOD: Participants in the US (N = 510), SE (N = 982), and NL (N = 510) completed an online survey assessing ED symptoms (binge eating, restriction, compensatory behaviors, and anxiety about being unable to exercise), general anxiety symptoms, and pandemic-related ED concerns about accessing food, lack of structure and social support, being in a triggering environment, and food and treatment costs. In the US and NL, respondents completed surveys beginning April 2020 and continuing monthly for a year. In SE, respondents completed baseline surveys in May 2020, a six-month follow-up around December 2020, and a 12-month follow-up in May 2021. RESULTS: Three patterns emerged: (1) a curvilinear course with the highest level of symptoms at baseline, declining through November 2020, and increasing through the rest of the year; (2) a linear declining course over time; and (3) a stable course with no changes. Worries about COVID-19 infection, lockdown, concerns about lack of structure and social support, and concerns about accessing food consistent with one's recovery meal plan predicted increases in ED symptoms. DISCUSSION: ED symptoms tracked with pandemic-related concerns in people with EDs. Conceptualizing predictors of symptoms may inform therapy and public health resources that reduce the impact of pandemics on mental health. PUBLIC SIGNIFICANCE: Our findings suggest that the COVID-19 pandemic had negative impacts on people with eating disorders, including amplification of mental health symptoms and stressors around peak periods of infection and COVID-19 restrictions. These findings inform medical providers, policy-makers, and community-based supports about the information and resource needs of this group to ensure efficient dissemination in future public health emergencies and during the ongoing COVID-19 pandemic.

Binge-eating disorder with and without lifetime anorexia nervosa: A comparison of sociodemographic and clinical features.

OBJECTIVE: To compare individuals who have experienced binge-eating disorder (BED) and anorexia nervosa (AN) (BED AN+) to those who have experienced BED and not AN (BED AN-). METHOD: Participants (N = 898) met criteria for lifetime BED and reported current binge eating. Approximately 14% had a lifetime diagnosis of AN. Analyses compared BED AN+ and BED AN- on sociodemographic variables and clinical history. RESULTS: The presence of lifetime AN was associated with more severe eating disorder symptoms, including earlier onset, more frequent, more chronic, and more types of eating disorder behaviors over the lifetime, as well as a higher lifetime prevalence of bulimia nervosa (BN). Participants with lifetime AN reported being more likely to have received treatments for BED or BN, had significantly lower minimum, current, and maximum BMIs, had more severe general anxiety, and were significantly more likely to be younger and female. In the full sample, the lifetime prevalence of unhealthy weight control behaviors was high and treatment utilization was low, despite an average 15-year history since symptom onset. Gastrointestinal disorders and comorbid anxiety, depression, and attention-deficit/hyperactivity disorder symptoms were prevalent. DISCUSSION: Individuals fared poorly on a wide array of domains, yet those with lifetime AN fared considerably more poorly. All patients with BED should be screened for mental health and gastrointestinal comorbidities and offered referral and treatment options. PUBLIC SIGNIFICANCE: Individuals experiencing binge-eating disorder have severe symptomology, but those who have experienced binge-eating disorder and anorexia nervosa fare even more poorly. Our study emphasizes that patients with binge-eating disorder would benefit from being screened for mental health and gastrointestinal comorbidities, and clinicians should consider history of unhealthy weight control behaviors to inform treatment and relapse prevention.

Perceptions and experiences with eating disorder treatment in the first year of COVID-19: A longitudinal qualitative analysis.

OBJECTIVE: The COVID-19 pandemic created significant challenges in accessing and receiving treatment for individuals with eating disorders (EDs). The purpose of this study is to explore perceptions of and experiences with ED treatment during the first year of the pandemic among individuals with past and self-reported EDs in the United States. METHODS: Online surveys were administered to adults (N = 510) with a past or current self-reported ED at 13 timepoints between April 2020 and May 2021. Using longitudinal qualitative analysis, 5651 free-text responses were examined to capture experiences with ED treatment and generate inferences of change over time. RESULTS: We categorized results into four sequential, temporal quarters and identified patterns that explained participants' perceptions of facilitators, barriers, and experiences with ED treatment over time: Quarter 1. Treatment Disruption and Reorienting Recovery; Quarter 2. Accumulating COVID-19 Stress and Virtual Treatment Woes; Quarter 3. A Continuation of Inadequate Care; and Quarter 4. Ongoing Adaptation and Adjustment to Uncertainty. Participant experiences were marked by numerous barriers to accessing care, challenges adjusting to virtual treatment, unmet treatment needs, and beginning acceptance of telehealth. DISCUSSION: Our findings present a timeline to help evaluate challenges related to navigating the switch to virtual care which created significant disruption to ED recovery. Participants spent much of the first year trying to adjust to unemployment, loss of insurance, and lack of access to in-person treatment. Future research should identify additional strategies to improve the receipt and experience of care for EDs. PUBLIC SIGNIFICANCE: Our findings suggest that individuals with eating disorders were significantly challenged by accumulating COVID-19 stress, worsening symptomatology, and limited access to effective treatment during the first year of the pandemic. This knowledge can guide clinicians, treatment centers, and policy makers in addressing the behavioral health needs of individuals impacted by disordered eating amidst emergent public health crises.

Longer-term impact of COVID-19 among individuals with self-reported eating disorders in the United States, the Netherlands, and Sweden.

OBJECTIVE: We assessed eating disorder (ED) illness status, symptomatology, treatment access, anxiety, and depression in the first year of the COVID-19 pandemic among individuals with a pre-existing ED in the United States (US), the Netherlands (NL), and Sweden (SE). METHODS: Participants completed online surveys in April-July 2020, at the early stage of the pandemic, and one year later. At one-year follow-up, we added questions addressing retrospective changes in ED symptoms, treatment, and anxiety/depression since the start of the COVID-19 pandemic. We present descriptive statistics and assess change in ED symptomatology, treatment, and anxiety/depression among those with an active or lingering ED. RESULTS: Participants (US n = 132; NL n = 219; SE n = 702) were mostly young and female with a history of anorexia nervosa (>60% in all three countries). Across countries, respondents reported impact of COVID-19 on ED symptoms at both time points, with improvement in US and NL at one-year follow-up, and stable but less impact on ED symptoms in SE. Furthermore, at one-year follow-up, roughly half of those in treatment reported reduced treatment access and quality, and the majority of the sample reported increased anxiety and depressive mood since the start of the pandemic. DISCUSSION: Our findings suggest that the self-perceived impact of COVID-19 changed over time but remained concerning even one year after the start of the pandemic. Clinicians, community organizations, and policy makers are encouraged to address potentially changing treatment needs in the face of public health emergency events. PUBLIC SIGNIFICANCE: Our findings suggest that the impact of COVID-19 on individuals with eating disorders decreased over time but remained concerning even one year after the start of the pandemic and that the impact differed across countries. Clinicians, community organizations, and policy makers are encouraged to incorporate this knowledge to address potentially changing treatment needs in the face of public health emergency events.

The efficacy of randomised controlled trials of cognitive behaviour therapy for perfectionism: a systematic review and meta-analysis.

Perfectionism is a transdiagnostic process across anxiety, depression, and eating disorders. The aim of this systematic review was to examine the efficacy of self-help and face to face CBT for perfectionism in reducing perfectionism and anxiety, depression, and eating disorders. A total of 15 randomised controlled trials of CBT for perfectionism were identified (N = 912 participants; mean pooled age = 23 years) which met inclusion criteria. There were medium or large effect sizes found on perfectionism measures; personal standards (g = 0.57, 95% CI = 0.43-0.72), concern over mistakes (g = 0.89, 95% CI = 0.71-1.08) and clinical perfectionism (g = 0.87, 95% CI = 0.70-1.04). There were medium effects for symptoms of eating disorders (g = 0.61, 95% CI = 0.36-0.87) and depression (g = 0.60, 95% CI = 0.28-0.91), and a small-medium effect on anxiety (g = 0.42, 95% CI = 0.21-0.62). There was no publication bias found. Limitations included the small number of trials included and lack of active treatment comparisons. Results suggested that CBT for perfectionism is efficacious in reducing perfectionism and symptoms of depression, anxiety and eating disorders. Future research should examine comparisons of CBT for perfectionism with other psychological treatments.

An exploratory investigation of predictors of outcome in face-to-face and online cognitive-behavioural therapy for bulimia nervosa.

OBJECTIVE: Cognitive-behavioural therapy (CBT) delivered face-to-face and via the internet reduces bulimia nervosa (BN) symptoms. However, our empirical understanding of factors affecting patient outcomes is limited. METHOD: Using data from a randomised, controlled trial comparing internet-based (CBT4BN, n = 78) with face-to-face (CBTF2F, n = 71) group CBT (97% female, M = 28 years), we examined general treatment (across conditions) and modality-specific predictors of end-treatment and 1-year outcomes (abstinence, binge-eating frequency, purging frequency). RESULTS: Improved eating disorder-related quality of life (EDQOL) during treatment and follow-up predicted abstinence at end-treatment and 1-year assessments. Improved EDQOL, disordered eating cognitions, and anxiety symptoms predicted less frequent binge eating and purging. Previous CBT and being employed predicted more frequent binge eating and purging at both assessments. Higher self-transcendence and self-directedness predicted less frequent binge eating. More severe binge eating and purging at baseline and end-treatment predicted more frequent binge eating and purging at subsequent assessments. Improved EDQOL was more strongly associated with positive outcome in CBT4BN; improved depressive symptoms and health-related QOL predicted positive outcome in CBT4BN but not CBTF2F. DISCUSSION: Symptom improvement and certain character traits predicted positive outcome, whereas more severe presentation and prior CBT experience predicted poorer outcome. Consideration of intreatment symptom improvement may facilitate care recommendations, particularly for internet-based modalities.

RICOPILI: Rapid Imputation for COnsortias PIpeLIne.

SUMMARY: Genome-wide association study (GWAS) analyses, at sufficient sample sizes and power, have successfully revealed biological insights for several complex traits. RICOPILI, an open-sourced Perl-based pipeline was developed to address the challenges of rapidly processing large-scale multi-cohort GWAS studies including quality control (QC), imputation and downstream analyses. The pipeline is computationally efficient with portability to a wide range of high-performance computing environments. RICOPILI was created as the Psychiatric Genomics Consortium pipeline for GWAS and adopted by other users. The pipeline features (i) technical and genomic QC in case-control and trio cohorts, (ii) genome-wide phasing and imputation, (iv) association analysis, (v) meta-analysis, (vi) polygenic risk scoring and (vii) replication analysis. Notably, a major differentiator from other GWAS pipelines, RICOPILI leverages on automated parallelization and cluster job management approaches for rapid production of imputed genome-wide data. A comprehensive meta-analysis of simulated GWAS data has been incorporated demonstrating each step of the pipeline. This includes all the associated visualization plots, to allow ease of data interpretation and manuscript preparation. Simulated GWAS datasets are also packaged with the pipeline for user training tutorials and developer work. AVAILABILITY AND IMPLEMENTATION: RICOPILI has a flexible architecture to allow for ongoing development and incorporation of newer available algorithms and is adaptable to various HPC environments (QSUB, BSUB, SLURM and others). Specific links for genomic resources are either directly provided in this paper or via tutorials and external links. The central location hosting scripts and tutorials is found at this URL: https://sites.google.com/a/broadinstitute.org/RICOPILI/home.

Genetics of eating disorders in the genome-wide era.

Enabled by advances in high throughput genomic sequencing and an unprecedented level of global data sharing, molecular genetic research is beginning to unlock the biological basis of eating disorders. This invited review provides an overview of genetic discoveries in eating disorders in the genome-wide era. To date, five genome-wide association studies on eating disorders have been conducted - all on anorexia nervosa (AN). For AN, several risk loci have been detected, and ~11-17% of the heritability has been accounted for by common genetic variants. There is extensive genetic overlap between AN and psychological traits, especially obsessive-compulsive disorder, and intriguingly, with metabolic phenotypes even after adjusting for body mass index (BMI) risk variants. Furthermore, genetic risk variants predisposing to lower BMI may be causal risk factors for AN. Causal genes and biological pathways of eating disorders have yet to be elucidated and will require greater sample sizes and statistical power, and functional follow-up studies. Several studies are underway to recruit individuals with bulimia nervosa and binge-eating disorder to enable further genome-wide studies. Data collections and research labs focused on the genetics of eating disorders have joined together in a global effort with the Psychiatric Genomics Consortium. Molecular genetics research in the genome-wide era is improving knowledge about the biology behind the established heritability of eating disorders. This has the potential to offer new hope for understanding eating disorder etiology and for overcoming the therapeutic challenges that confront the eating disorder field.

Shared genetic risk between eating disorder- and substance-use-related phenotypes: Evidence from genome-wide association studies.

Eating disorders and substance use disorders frequently co-occur. Twin studies reveal shared genetic variance between liabilities to eating disorders and substance use, with the strongest associations between symptoms of bulimia nervosa and problem alcohol use (genetic correlation [rg ], twin-based = 0.23-0.53). We estimated the genetic correlation between eating disorder and substance use and disorder phenotypes using data from genome-wide association studies (GWAS). Four eating disorder phenotypes (anorexia nervosa [AN], AN with binge eating, AN without binge eating, and a bulimia nervosa factor score), and eight substance-use-related phenotypes (drinks per week, alcohol use disorder [AUD], smoking initiation, current smoking, cigarettes per day, nicotine dependence, cannabis initiation, and cannabis use disorder) from eight studies were included. Significant genetic correlations were adjusted for variants associated with major depressive disorder and schizophrenia. Total study sample sizes per phenotype ranged from ~2400 to ~537 000 individuals. We used linkage disequilibrium score regression to calculate single nucleotide polymorphism-based genetic correlations between eating disorder- and substance-use-related phenotypes. Significant positive genetic associations emerged between AUD and AN (rg = 0.18; false discovery rate q = 0.0006), cannabis initiation and AN (rg = 0.23; q < 0.0001), and cannabis initiation and AN with binge eating (rg = 0.27; q = 0.0016). Conversely, significant negative genetic correlations were observed between three nondiagnostic smoking phenotypes (smoking initiation, current smoking, and cigarettes per day) and AN without binge eating (rgs = -0.19 to -0.23; qs < 0.04). The genetic correlation between AUD and AN was no longer significant after co-varying for major depressive disorder loci. The patterns of association between eating disorder- and substance-use-related phenotypes highlights the potentially complex and substance-specific relationships among these behaviors.

Validity of the compulsive exercise test in regular exercisers.

Measurement of compulsive exercise is important for the study of eating pathology in individuals who regularly participate in sport and exercise. The current study examined the factor structure, internal consistency and validity of the compulsive exercise test (CET) in regular exercisers. Participants were recruited via the internet and from sport clubs (n = 313 adults; M = 32 years; 57% female). A three-factor model for the CET was supported which included the weight control exercise, avoidance and rule-driven behaviour, and mood improvement subscales (fit statistics for the three-factor model: χ2SB = 4.39; CFI = .95; NNFI = .94, RMSEA = .100, 95% CI: .093-.110, AIC = 656.92). The subscales lack of exercise enjoyment and exercise rigidity were not retained. All factors demonstrated acceptable internal consistency with Cronbach's α = .77 to .91. The weight control exercise and avoidance and rule-driven behaviour subscales were significantly related to eating disorder symptoms. Given the association between CET subscales and eating disorder symptoms, the CET three-factor model may be informative when assessing eating pathology in individuals who regularly exercise.

Early impact of COVID-19 on individuals with self-reported eating disorders: A survey of ~1,000 individuals in the United States and the Netherlands.

OBJECTIVE: We evaluated the early impact of COVID-19 on people with self-reported eating disorders. METHOD: Participants in the United States (US, N = 511) and the Netherlands (NL, N = 510), recruited through ongoing studies and social media, completed an online survey that included both quantitative measures and free-text responses assessing the impact of COVID-19 on situational circumstances, eating disorder symptoms, eating disorder treatment, and general well-being. RESULTS: Results revealed strong and wide-ranging effects on eating disorder concerns and illness behaviors that were consistent with eating disorder type. Participants with anorexia nervosa (US 62% of sample; NL 69%) reported increased restriction and fears about being able to find foods consistent with their meal plan. Individuals with bulimia nervosa and binge-eating disorder (US 30% of sample; NL 15%) reported increases in their binge-eating episodes and urges to binge. Respondents noted marked increases in anxiety since 2019 and reported greater concerns about the impact of COVID-19 on their mental health than physical health. Although many participants acknowledged and appreciated the transition to telehealth, limitations of this treatment modality for this population were raised. Individuals with past histories of eating disorders noted concerns about relapse related to COVID-19 circumstances. Encouragingly, respondents also noted positive effects including greater connection with family, more time for self-care, and motivation to recover. DISCUSSIONS: COVID-19 is associated with increased anxiety and poses specific disorder-related challenges for individuals with eating disorders that require attention by healthcare professionals and carers.

Structure and validity of the Clinical Perfectionism Questionnaire in female adolescents.

BACKGROUND: Perfectionism is a transdiagnostic risk factor across psychopathology. The Clinical Perfectionism Questionnaire (CPQ) was developed to assess change in order to provide clinical utility, but currently the psychometric properties of the CPQ with adolescents is unknown. AIMS: To assess the factor structure and construct validity of the CPQ in female adolescents. METHOD: The CPQ was administered to 267 females aged 14-19 years of age. Confirmatory factor analysis (CFA) was used to examine the validity of the two-factor model and a second-order factor model. Pearson correlations were used to evaluate the relationships between the CPQ and a wide range of measures of perfectionism, psychopathology and personality traits. RESULTS: The study demonstrated internal consistency, construct validity and incremental validity of the CPQ in a sample of female adolescents. The CFA in the present study confirmed the two-factor model of the CPQ with Factor 1 relating to perfectionistic strivings and Factor 2 representing perfectionistic concerns. The second-order two factor model indicated no deterioration in fit. CONCLUSIONS: The two-factor model of the CPQ fits with the theoretical definition of clinical perfectionism where the over-dependence of self-worth on achievement and concern over mistakes are key elements. The CPQ is suitable for use with female adolescents in future research that seeks to better understand the role of perfectionism in the range of mental illnesses that impact youth.

Eating disorder recovery in men: A pilot study.

OBJECTIVE: This pilot study examined the validity of a comprehensive definition of recovery (physical, behavioral, and cognitive recovery indices) for the first time in men. METHOD: Men with an eating disorder history were recruited from former patients at eating disorder centers, university campuses, and fitness centers/gyms. At baseline and a 12-month follow-up, data were collected via online surveys, diagnostic interviews, and measured weight and height from men with an eating disorder history (n = 36) and men with no eating disorder history (n = 27). RESULTS: Of the men with an eating disorder history, 15 met criteria for an eating disorder, 7 met criteria for partial recovery, and 5 for full recovery. Men who met criteria for full recovery did not differ significantly from men with no eating disorder history and had significantly lower levels of broad eating pathology, thinness and restricting expectancies, body shame, difficulties in stopping thoughts about body, food, or exercise, and male body attitudes related to muscularity and body fat than men with an eating disorder. Men meeting criteria for full recovery had higher levels of body acceptance and intuitive eating than men who met criteria for partial recovery or an eating disorder. In terms of predictive validity, of those fully recovered at baseline, 60% also met full recovery criteria at follow-up. DISCUSSION: Preliminary findings suggest that a comprehensive definition of recovery applies to men. Although research with larger samples is needed, this research provides some optimism for the potential of recovery in men.

Prenatal and perinatal risk factors for eating disorders in women: A population cohort study.

OBJECTIVE: The fetal programming model hypothesizes that developmental programming in utero and in early life induces adaptations that predetermine the adult phenotype. This study investigated whether prenatal/perinatal complications are associated with lifetime eating disorders in women. METHOD: Participants included 46,373 adult women enrolled in the Norwegian Mother and Child Cohort Study (den norske Mor & barn-undersøkelsen [MoBa]). MoBa mothers and their mothers (MoBa grandmothers) were the focus of the current study. MoBa mothers with lifetime eating disorders were compared to a referent group. RESULTS: MoBa mothers who weighed more at birth (birth weight, adjusted odds ratio [OR] = 1.14; 95% confidence interval [CI]: 1.10-1.19) or were born large-for-gestational-age (adjusted OR = 1.39; 95% CI: 1.27-1.52) were more likely to develop binge-eating disorder in later life. MoBa mothers who weighed less at birth were more likely to develop anorexia nervosa (birth weight, adjusted OR = 0.88; 95% CI: 0.81-0.95). Bulimia nervosa and purging disorder (PD) were not significantly predicted by the prenatal and perinatal factors examined. DISCUSSION: Results of this study, which include the first known investigation of prenatal and perinatal factors in binge-eating disorder and PD, suggest that fetal programming may be relevant to the development of anorexia nervosa and binge-eating disorder. Future genetically informative research is needed to help disentangle whether these associations are a function of genetic influences or a true environmental fetal programming effect.

Family involvement in eating disorder treatment among Latinas.

Latinos are less likely to seek health care for eating disorders and more likely to drop out of treatment than members of other ethnic groups, highlighting existing challenges to engagement in traditional mental health care. This study explored the role of family in the treatment of adult Latinas with eating disorders through content analysis of family sessions adjunctive to cognitive behavioral therapy. This study yielded insight into the experiences of 10 Latinas with eating disorders (M age = 39.90 years) and 10 relatives (M age = 39.50) from the Promoviendo una Alimentación Saludable trial who were randomly selected to receive six family enhancement sessions. Data from 53 sessions were analyzed using a qualitative content analysis approach. Family intervention might serve as a valuable adjunct to conventional treatment by positively influencing social, family, and emotional support for Latinas with eating disorders.

Children of Parents with Eating Disorders.

PURPOSE OF REVIEW: Our primary goal in this article is to review recent findings (from 2015 and on) concerning children of parents with eating disorders. This review addresses the question of whether the offspring of parents with past or present eating disorders have adverse outcomes. This update is timely and informative because recent research includes controlled studies and large cohort designs and earlier reviews relied on case report evidence. RECENT FINDINGS: Despite substantial diversity in study design, sample size, and parental eating disorder definition, overall, existing research suggests that the children of parents with eating disorders exhibit compromised development: a greater risk of perinatal complications; a tendency toward extremes of growth at birth; greater problems in feeding and eating behaviors and greater incidence of eating disorder symptoms; more psychological and socioemotional difficulties; and more negative qualities to parent-child interactions. Data on children's cognitive outcomes is thus far inconsistent. Given the relatively high incidence of eating disorder history in individuals of childbearing age, research into its potential effects on children is necessary. However, the methodological shortcomings and a limited evidence base caution in drawing conclusions. Nevertheless, mental health services should address the possible problems that these children face and offer tailored programs.

An Overview of Conceptualizations of Eating Disorder Recovery, Recent Findings, and Future Directions.

PURPOSE OF REVIEW: This review delineates issues in the conceptualization and operationalization of eating disorder recovery, highlights recent findings about recovery (since 2016), and proposes future directions. RECENT FINDINGS: A longstanding problem in the field is that there are almost as many different definitions of recovery in eating disorders as there are studies on the topic. Yet, there has been a general shift to accepting that psychological/cognitive symptoms are important to recovery in addition to physical and behavioral indices. Further, several operationalizations of recovery have been proposed over the past two decades, and some efforts to validate operationalizations exist. However, this work has had limited impact and uptake, such that the field is suffering from "broken record syndrome," where calls are made for universal definitions time and time again. It is critical that proposed operationalizations be compared empirically to help arrive at a consensus definition and that institutional/organizational support help facilitate this. Themes in recent recovery research include identifying predictors, examining biological/neuropsychological factors, and considering severe and enduring anorexia nervosa. From qualitative research, those who have experienced eating disorders highlight recovery as a journey, as well as factors such as hope, self-acceptance, and benefiting from support from others as integral to the process of recovery. The field urgently needs to implement a universal definition of recovery that is backed by evidence, that can parsimoniously be implemented in clinical practice, and that will lead to greater harmonization of scientific findings.

Implications of DSM-5 for the diagnosis of pediatric eating disorders.

OBJECTIVE: The aim of the study was to compare the DSM-IV, DSM-5, and ICD-10 eating disorders (ED) nomenclatures to assess their value in the classification of pediatric eating disorders. We investigated the prevalence of the disorders in accordance with each system's diagnostic criteria, diagnostic concordance between the systems, and interrater reliability. METHOD: Participants were 1062 children and adolescents assessed at intake to a specialist Eating Disorders Program (91.6% female, mean age 14.5 years, SD = 1.75). Measures were collected from routine intake assessments. RESULTS: DSM-5 categorization led to a lower prevalence of unspecified EDs when compared with DSM-IV. There was almost complete overlap for specified EDs. Kappa values indicated almost excellent agreement between the two coders on all three diagnostic systems, although there was higher interrater reliability for DSM-5 and ICD-10 when compared with DSM-IV. DISCUSSION: DSM-5 nomenclature is useful in classifying eating disorders in pediatric clinical samples.

Weight suppression and weight elevation are associated with eating disorder symptomatology in women age 50 and older: Results of the gender and body image study.

OBJECTIVE: Weight suppression (WS), the difference between highest past non-pregnancy weight and current weight, predicts negative outcomes in eating disorders, but the impact of WS and related weight constructs are understudied in nonclinical, midlife populations. We examined WS (current weight < highest weight) and weight elevation (WE), the opposite of WS (current weight > lowest weight) and their associations with eating psychopathology in women aged 50+. METHOD: Participants were a community-based sample (N = 1,776, Mage = 59) who completed demographic and eating psychopathology questions via online survey. WS, WE, and WS × WE were tested as predictors of outcome variables; BMI and medical conditions that affect weight were controlled for. RESULTS: Individuals that were higher on WS and WE were most likely to engage in current weight loss attempts, dieting in the past 5 years, and extreme lifetime restriction. Individuals with higher WS were more likely to experience binge eating, greater frequency of weight checking, overvaluation of shape and weight, and lifetime fasting. Individuals with higher WE were more likely to report negative life impacts of eating and dieting. Higher WS and WE each predicted higher levels of skipping meals over the lifetime. DISCUSSION: This novel study investigated WS in midlife women and introduced a new conceptualization of weight change (WE) that may be more relevant for aging populations given that women tend to gain weight with age. The findings implicate the utility of investigating both WS and WE as factors associated with eating psychopathology in midlife women.
