Abstract
The Eating Disorder Examination-Questionnaire (EDE-Q) is a widely used self-report measure of eating pathology. Despite widespread use, investigations of its factor structure have proved inconclusive and rarely supported the "original" interpretation. The current study evaluates several proposed factor solutions of the EDE-Q using latent variable analysis in a sample of adult women with anorexia nervosa (AN). A total of 804 patients from a specialist treatment center in the United States participated in the study. Confirmatory factor analysis was conducted on 22 EDE-Q items assessing attitudinal features of eating pathology. Findings suggested that three full-item versions (none of which was the "original" interpretation) fit the data adequately, with a brief, seven-item version showing excellent fit. The study is one of the first to examine this within a sample of women with AN and provides an empirical foundation for how best to use the EDE-Q among clinical and research participants with AN. Findings suggest that the "original" factor structure lacks structural validity in women with AN. Its use should generally be discouraged, and future work on screening and treatment outcomes might consider the EDE-Q7.

J Clin Med 2024; 13:3255.

Abstract
Background: Adolescents' early responses and overall outcomes during anorexia nervosa (AN) treatment may differ by patient gender, raising the question of whether evaluating clinical data during AN treatment may require different criteria. Methods: We investigated, using patient records, whether young men and young women with AN differed in terms of early treatment response (defined as weight change and variability within the first 14 days) and whether early treatment responses predicted treatment outcomes similarly across genders. Results: Weight changes predicted patient discharge weight across all gender groups. Weight variability predicted higher disordered eating psychopathology and higher body image insecurities at discharge. Gender differences emerged only for weight gain, which was more pronounced for young men, and gender modulated the effects of weight gain and variability on general psychopathology outcomes. Conclusions: The present findings suggest that early weight changes and weight variability are similarly important predictors of AN treatment outcomes in adolescents but also hint at possible gender differences in terms of the link between weight change and, respectively, variability on general psychopathology.

Abstract
Arab, Middle Eastern, and North African (A-MENA) American women are often subject to intersectional discrimination, and they have also not been traditionally recognized as a distinct racial group in disordered eating literature. No study to date has provided descriptive information on disordered and emotional eating A-MENA American women, nor has examined perceptions of widely used measurements of eating pathology in this population. The current study generated descriptive information among A-MENA women on two widely used measures of eating pathology, the Eating Disorder Examination Questionnaire (EDE-Q) and the Emotional Eating Scale (EES). Participants (N = 244) were A-MENA adult women were recruited via social media and snowball sampling. Qualitative findings provide potential sociocultural predictors of disordered eating that should be further explored, such as bicultural identity and family pressures/comments toward appearance. Secondly, themes from the EES-R indicate adding emotion of shame and considering identity-related stress. The current study provides prevalence data and future directions of research on widely used eating pathology and appearance attitude measurements for A-MENA American women.

An examination of adults with atypical anorexia nervosa at admission to treatment at higher levels of care: An attempt to increase diagnostic clarity. Int J Eat Disord 2024; 57:848-858.

Abstract
OBJECTIVE Anorexia nervosa (AN) is a serious illness with a high mortality rate and multiple physiological complications. The vague definition of atypical AN allows for subjective interpretation. This retrospective study aimed to focus future research on the operational definition of atypical AN by examining four factors associated with atypical AN at admission to higher level of care treatment. METHODS Adults with atypical AN (n = 69) were examined within sample analyses among four groups: (1) >10% versus ≤10% weight loss; (2) weight loss within the previous 3 months versus >3 months; (3) engaging in purging behaviors versus absence of purging behaviors; and (4) endorsing versus not endorsing significant cognitive aspects of AN. RESULTS Patients with atypical AN endorsed elevated ED cognitions on the Eating Disorder Examination-Questionnaire and depressive symptoms; a lack of association was found between weight loss severity and weight loss time frame with depressive symptoms, eating concern, and restraint. Purging behavior was associated with a higher expected body weight percentage (%EBW) and dietary restraint, while greater AN cognitions were associated with a higher EBW and weight loss percentage. Few patients demonstrated bradycardia, hypophosphatemia, or amenorrhea. DISCUSSION This study demonstrated the severity of ED cognitions and depressive symptoms in this atypical AN sample and provided directions for future studies in the nosology of atypical AN. It may be important to distinguish between individuals with atypical AN who are purging and those who are not. Atypical AN was associated with a low frequency of physiological disturbances. PUBLIC SIGNIFICANCE This study provides further clarification regarding the operational definition of atypical AN; currently, a constellation of symptoms under Other Specified Feeding or Eating Disorders. This study was consistent with previous research in reporting severe eating disorder cognitions in adults with atypical AN, and noted the potential importance of distinguishing a purging distinction. A minority of patients in this study had physiological impairments.

Abstract
This study evaluated symptoms assessed in common measures of eating disorder pathology and tested overlap to evaluate the extent to which measures may be interchangeable. Six measures were included: Bulimia Test-Revised, Eating Attitudes Test-26, Eating Disorder Diagnostic Scale, Eating Disorder Examination Questionnaire, Eating Pathology Symptoms Inventory, and Questionnaire for Eating Disorder Diagnoses. Content overlap was quantitatively estimated using the Jaccard Index. Mean overlap was low (.195), likely due to the wide range of symptoms (87) assessed. The mean overlap of each measure with all others was .117 - .267, and the overlap among individual measures was .083 - .382. Implications of low overlap among measures include variable characterization of eating disorder phenotypes and the risk for lower generalizability of findings due to measurement variability.

Abstract
Eating disorder (ED) research and practice have been shaped by prevailing stereotypes about who EDs are most likely to affect. Subsequently, the field has prioritized the needs and concerns of affluent, cisgender, heterosexual, white girls and women to the exclusion of others, especially people marginalized based on their race, ethnicity, sexual orientation, and/or gender identity. However, EDs exist across diverse groups and actually occur with elevated prevalence in several marginalized groups. Growing research points to differences in the drivers of EDs in such groups (e.g. desire to attain the curvy rather than thin ideal; dietary restraint due to food insecurity rather than weight/shape concerns), yet tools typically used for screening and intervention evaluation do not capture eating pathology driven by such factors. In this commentary, we describe gaps in existing ED assessment tools and argue these gaps likely underestimate EDs among marginalized groups, bias who is invited, participates in, and benefits from ED prevention programs, and obscure potential group differences in the efficacy of such programs. We also discuss the potential of these ramifications to exacerbate inequities in EDs. Finally, we outline recommendations to overcome existing gaps in measurement and, consequently, advance equity in the realm of ED prevention.

Abstract
BACKGROUND Eating disorders are seen mainly as a problem affecting women, not just by the public at large, but also in specialized circles. Although it is true that more women than men suffer from all types of eating disorder, pertinent reviews have clearly shown that they do indeed occur in men, and that the available evidence on the matter is limited. The stigmatization of men with eating disorders makes it harder for these men, and for the relevant professionals, to recognize the symptoms and to seek or provide help. METHODS This review is based on publications retrieved by a selective search in PubMed on the epidemiological, diagnostic, clinical, and therapeutic aspects of eating disorders in men. RESULTS Current estimated lifetime prevalences in men are 0.2% for anorexia nervosa, 0.6% for bulimia nervosa, and 1% for bingeeating disorder; the corresponding figures for women are 1.4%, 1.9%, and 2.8%. Men and women may display different manifestations. Women are thought to be mainly seeking a slim figure and weight reduction; men, a muscular build. The established Germanlanguage screening and diagnostic tools, however, do not cover the types of symptoms that are more common in men. Little is known about whether treatment yields comparable results in men and women. CONCLUSION It is important to combat the stigmati - zation of men with eating disorders and to remove the obstacles to their appropriate diagnosis and treatment. The current methods of screening and diagnosis need to be adapted to take account of the special aspects of abnormal eating behavior in men. It remains unclear whether and how the disorderspecific treatment of these conditions in men should differ from their treatment in women.

Abstract
The role of therapeutic alliance within psychological treatments for eating disorders (EDs), including those delivered remotely, is well established. However, few studies have investigated alliance in guided self-help, a widely recommended first-line treatment for EDs characterised by regular binge eating. Using data from a randomised controlled trial, the current study examined both facilitator and patient assessments of alliance within e-mail-assisted and face-to-face guided self-help and looked at associations between alliance, ED symptoms and ED-related impairment. One hundred thirteen patients and 11 facilitators completed measures of alliance during and following a course of guided self-help. Whilst ratings were reliable across patients and facilitators, alliance scores were higher both in the patient sample and in the face-to-face condition. Ratings of alliance showed no correlations with ED symptoms at post-treatment, and early alliance was not significantly associated with outcome, which could inform how early symptom change is encouraged in guided self-help.

Abstract
BACKGROUND Eating disorders (EDs) are severe and multifaceted mental health issues that affect a person's perception of their body weight in relationship with food. Existing evidence shows that EDs significantly affect the physical and emotional health of individuals with Type-2 Diabetes (T2D) and are associated with impaired metabolic control and a high risk of medical complications, including higher mortality rates. However, there is a paucity of research looking into the prevalence of EDs. OBJECTIVE A cross-sectional study was conducted to map the prevalence of EDs and to assess its pattern among adults with T2D from Ahmedabad City, Gujarat, India. METHODOLOGY Two hundred fifty-four T2D individuals aged 30-60 were enrolled in the study. A questionnaire was developed using the Sick, Control, One, Fat, Food (SCOFF) questionnaire and a five-question screening tool intended to identify the possibility of EDs as well as the Eating Disorder Examination-Questionnaire (EDEQ), which is used to identify the pattern of EDs with subscales like Restraint, Eating Concern, Shape Concern, and Weight Concern. Written informed consent was obtained from all participants. Descriptive statistics, Pearson's Correlation, and Logistic Regression analysis were used. A p-value of < 0.05 was considered significant. RESULTS The results revealed that 90 (35%) of the total participants were at a high risk of EDs. Among these, 54 (21% of the total population) were males, and 36 (14% of total participants) were females. There was a mild statistically significant negative correlation between age and exercise with the presence of ED (r = -0.151, p = 0.016 and r = -0.186, p = 0.003, respectively), while education showed a significant positive correlation (r = 0.150, p = 0.017). Males had significantly higher scores for eating concerns than females (19.75±4.88 vs 17.88±5.92; p = 0.008). The logistic regression model revealed that education was a significant predictor of EDs (OD = 1.47, 95% CI 1.00-2.16 and p = 0.04). CONCLUSION The study identified that people with T2D are at risk of EDs, and eating concerns worry them the most. Thus, counseling sessions should focus on identifying the determinants of EDs and educating the patients regarding quality eating. This will have implications in addressing the other morbidities as well as health risks related to BMI; especially obesity as it is more prevalent in the T2D population.

Abstract
Recent research suggests high rates of posttraumatic stress disorder (PTSD) and eating disorder (ED) comorbidity in women veterans. This study aims to expand the literature by examining associations between PTSD and ED diagnoses and symptoms in this population. We assessed probable PTSD diagnosis and symptom clusters (intrusion, avoidance, arousal and reactivity, and negative alterations in cognition and mood [NACM]), as well as probable Binge Eating Disorder (BED) diagnosis and ED subscales (dietary restraint, shape/weight overvaluation, and body dissatisfaction) in a sample of women veterans (N = 371). We investigated significance at the standard p < .05, and the Bonferroni-corrected p < .005 cut-off to adjust for experiment-wise error. Overall, we found that probable PTSD was associated with provisional BED (p < .001) using logistic regression at both cut-offs. Probable PTSD was associated with all ED subscales (all p's < 0.003) using linear regression models also at both cut-offs. Provisional BED was associated with NACM at p < .05 (p = .046), though it did not meet significance at our conservative cut-off. NACM was also associated with shape/weight overvaluation (p = .02) and a global ED score (p = .01) at p < .05, but not at our conservative cut-off; arousal was associated with shape/weight overvaluation (p = .04) and the global ED score (p = .02) at p < .05, but not at our conservative cut-off. Our findings may further guide how ED-related topics can be integrated in PTSD treatment for women veterans with comorbid PTSD and ED.

Abstract
Eating disorders are severe and often chronic mental illnesses that are associated with high impairment and mortality rates. Recent estimates suggest that eating disorder prevalence rates are on the rise, indicating an increased need for accurate assessment and detection. The current review provides an overview of transdiagnostic eating disorder assessments, including interview, self-report, health and primary care screeners, and technology-based and objective assessments. We focused on assessments that are transdiagnostic in nature and exhibit high impact in the field. We provide recommendations for how these assessments should be used in research and clinical settings. We also discuss considerations that are crucial for assessment, including the use of a categorical versus dimensional diagnostic framework, assessment of eating disorders in related fields (i.e., anxiety and depression), and measurement-based care for eating disorders. Finally, we provide suggestions for future research, including the need for more research on short transdiagnostic screeners for use in health care settings, standardized assessments for ecological momentary assessment, development of state-based assessment of eating disorder symptoms, and consideration of assessment across multiple timescales.

Abstract
BACKGROUND Although eating disorder (ED) models display some differences in theory and treatment approach, cognitive-behavioural, schema-focused, and disorder-specific models all highlight the fundamental nature of cognitions as key factors in ED development and maintenance processes. As such, it is vital that ED cognitions continue to be assessed and monitored as therapeutic targets and treatment outcomes as well as being examined as constructs in empirical research. This review aimed to systematically identify and evaluate the psychometric properties of existing self-report measures of ED cognitions. METHODS A systematic review protocol was registered using the international prospective register of systematic reviews (PROSPERO; CRD42023440840). Included studies described the development, validation and/or the psychometric evaluation of a measure (or subscale) that was specifically developed to solely assess ED cognitions (that is thoughts, expectations, assumptions, or beliefs), in English-speaking, adult populations. The search was conducted using three electronic databases: PsycINFO, MedLine, and Embase. Two independent reviewers conducted screening, selection and evaluation of the psychometric properties of relevant measures using a standardised, well-established quality appraisal tool. RESULTS Of the initial search of 7581 potential studies, 59 met inclusion criteria and described the psychometric evaluation of 31 measures (or subscales) of ED cognitions. The findings from the current review indicate that of the included measures, none currently meet all nine criteria of adequate psychometric properties. The Eating Beliefs Questionnaire (EBQ; and EBQ-18), and the Eating Disorder Inventory Body Dissatisfaction subscale (EDI [BD]) currently possess the most evidence supporting their validity, reliability, and clinical utility. CONCLUSIONS The findings of the current systematic review provide guidance for future researchers to focus efforts on improving evidence for the validity, reliability and utility of self-report measures of ED cognitions. Overall, the present study has provided a detailed and systematic evaluation to support researchers and clinicians in future selection of measures of ED cognitions dependent on the specific aims of their research and treatment.

Abstract
Establishing normative data for questionnaires is essential for the accurate interpretation of scores, given that these norms can vary according to different subpopulations and treatment contexts. The purpose of this study was to establish norms for the Eating Disorder Examination-Questionnaire (EDE-Q) among adults receiving higher levels of care (HLOCs) for the treatment of eating disorders. Participants were 2,283 people receiving treatment at the inpatient, residential, partial hospitalization, or intensive outpatient levels of care. The EDE-Q was completed at admission. Patients with anorexia nervosa-restricting subtype (AN-R) had the lowest EDE-Q Global scores when compared with all other eating disorder diagnoses. When compared with intensive outpatient care, only those in residential treatment had higher EDE-Q Global scores. This study is among the first to describe norms for the EDE-Q in a large sample of adults receiving various HLOCs. Programs utilizing the EDE-Q to assess treatment outcomes can use these findings to aid people in interpreting their scores.

Comparison between the brief seven-item and full eating disorder examination-questionnaire (EDE-Q) in clinical and non-clinical female Norwegian samples. J Eat Disord 2023; 11:194.

Abstract
BACKGROUND The Eating Disorder Examination-Questionnaire (EDE-Q) is among the most widely used self-report measures of eating disorder (ED) psychopathology. There is a need for brief versions of the EDE-Q that can be used for general assessment and screening purposes. A three-factor 7-item version (EDE-Q7) seems particularly promising but there is a need for more well-powered studies to establish the psychometric properties in both patient and community samples. Moreover, comparing the EDE-Q7 with the full EDE-Q would be beneficial in determining its utility. In the present study, we provide a psychometric comparison between the brief EDE-Q7 and the full EDE-Q in a large sample of both patients and community comparisons. METHODS We pooled available datasets collected in Norway to amass a large female sample comprising both patients (n = 1954, Mage = 28 years) and community comparisons (n = 2430, Mage = 31 years). We investigated the psychometric properties of both versions, including their internal consistency, factor structure, and ability to discriminate between patients and community comparisons. RESULTS The EDE-Q7 showed similar distributions of scores compared to the full EDE-Q but produced higher scores. Results indicated that the EDE-Q7 have acceptable internal consistency and is adequately able to discriminate between clinical and non-clinical samples. A cut-off threshold of 3.64 was optimal in discriminating between patients and comparisons. We also found support for the three-factor solution for the EDE-Q7, indicating good structural validity. In contrast, we did not find support for the originally proposed four-factor solution of the full EDE-Q. CONCLUSIONS We find that the brief EDE-Q7 performs close to the full EDE-Q in several respects. Our findings indicate that the brief EDE-Q7 may be a viable alternative to the full EDE-Q in situations where response burden is an issue (e.g., epidemiological studies). However, the EDE-Q7 may hold limited value over the full EDE-Q in clinical settings, due to the small number of items and lack of assessment of behavioral features.

Abstract
OBJECTIVE To examine the psychometric properties of the Parent Eating Disorder Examination Questionnaire (PEDE-Q), developed to improve eating disorder (ED) assessment among youth by including parents as informants. METHODS A multi-site, transdiagnostic sample of 355 adolescents with EDs completed the Eating Disorder Examination Questionnaire (EDE-Q) and their parents completed the PEDE-Q. RESULTS The internal consistencies of the PEDE-Q subscales were on par with established EDE-Q ranges (.73 to .90), both when examined using the original four-factor EDE-Q subscales and the seven-item, three-factor subscales of the brief EDE-Q. Statistically significant medium- to large-sized correlations and poor to moderate levels of agreement were found between the corresponding EDE-Q and PEDE-Q subscales. Receiver-operator characteristic (ROC) curves showed that the PEDE-Q had a statistically significant area under the curve (AUC) to maximize sensitivity and specificity in diagnosing full-syndrome AN, whereas the EDE-Q did not. Based on chi-square analyses, the PEDE-Q identified a statistically significantly greater number of AN cases than the EDE-Q. The EDE-Q yielded a BN diagnosis more frequently than the PEDE-Q, although this difference was not statistically significant. DISCUSSION Results suggest that the PEDE-Q has good psychometric properties and provides incremental information that can aid in the assessment and diagnosis of adolescents with EDs, particularly those with AN. PUBLIC SIGNIFICANCE There exist complex challenges to identifying clinically significant eating disorders among youth. The PEDE-Q is a questionnaire measure that improves eating disorder assessment among children and adolescents by asking parents to report on the symptoms and behaviors they have observed in their child and that youth may not fully disclose. The PEDE-Q can aid in the diagnosis of adolescents with eating disorders, particularly those with anorexia nervosa.

Abstract
Introduction Eating disorders (EDs) are among the most severe mental disorders in women and men, often associated with high symptom burden and significant limitations in daily functioning, frequent comorbidities, chronic course of illness, and even high mortality rates. At the same time, differences between men and women with EDs remain poorly explored. Methods In this study, we compared 104 men to 104 diagnosis-matched women with EDs regarding sociodemographic and clinical features. Using latent class mixture modelling, we identified four distinct patient subgroups based on their sociodemographic features. Results Men with EDs had significantly higher odds than women to belong to a "single-childfree-working" class. Moreover, while there were few overall differences in ED-related symptoms and general psychopathology between men and women, single-childfree-working men with EDs presented with higher general psychopathology symptoms than men in the other classes. Discussion We discuss how considering sex and gender along with further sociodemographic differences in EDs may help to improve ED diagnosis and treatment.

Abstract
This study examined the dimensional structure of the German Eating Disorder Examination-Questionnaire (EDE-Q) in clinical groups of women with Anorexia Nervosa (AN; N = 821), Bulimia Nervosa (BN; N = 573), and Binge-Eating Disorder (BED; N = 359) using Exploratory Graph Analyses (EGA). The EGA yielded a 12-item-four-dimension structure for the AN group (subscales "Restraint", "Body Dissatisfaction", "Preoccupation", "Importance"), a 20-item-five-dimension structure for the BN group (subscales "Restraint", "Body Dissatisfaction", "Eating Concern", "Preoccupation", "Importance"), and a 17-item-four-dimension structure for the BED group (subscales "Restraint", "Body Dissatisfaction", "Concern", "Importance"). This first investigation of the EDE-Q's dimensional structure using EGA suggests that the original factor model may be suboptimal for specific clinical ED samples and that alternative scoring should be considered when screening specific cohorts or evaluating the effects of interventions.

Abstract
OBJECTIVE The current study extended research examining the validity of the two-step Water Load Test (WLT-II), an objective, laboratory-based measure of gastric interoception, by investigating the validity of the WLT-II in a nonclinical sample and testing its contribution to the prediction of eating and weight/shape concerns. METHODS Participants (n = 129, 73.6% cisgender female, M = 20.13 years old) completed the WLT-II Questionnaire and two-step WLT-II, as well as self-report measures of eating and weight/shape concerns (Eating Disorder Examination Questionnaire; EDE-Q) and interoception (Multidimensional Assessment of Interoceptive Awareness-2; Intuitive Eating Scale-2 Reliance on Hunger and Satiety), in the lab at a large southeastern university. Data analysis included repeated measures ANOVA, correlations, and a series of hierarchical linear regressions. RESULTS Participants reported considerably more discomfort after the "maximum fullness" trial compared to the "satiation" trial. The WLT-II's objective measure of gastric interoception (sat_%) was not significantly correlated with the self-report measures of interoception and did not predict EDE-Q Dietary Restraint, Eating Shame, or Weight/Shape Concerns. Unexpectedly, greater gastric sensitivity was associated with less EDE-Q Preoccupation/Restriction. Exploratory analyses suggested a possible nonlinear association. DISCUSSION These results support the validity of the WLT-II in its ability to create, measure, and distinguish between the states of satiation and maximum fullness. However, results also suggest additional work is needed to better understand what the WLT-II's sat_% measure is capturing, as well as investigate potential nonlinear associations of the WLT-II with disordered eating. PUBLIC SIGNIFICANCE Interoception, or the processing of internal body signals, shows important links to disordered eating. Despite the clear relevance of gastric interoception to disordered eating-such as the ability to detect satiety signals-existing research has relied on general, self-report measures of interoception. This study examined the utility of a laboratory-based measure of gastric interoception. Results suggested mixed support for its validity and utility for predicting eating and weight/shape concerns in a nonclinical population.

Abstract
BACKGROUND Previous investigations on the Eating Disorder Examination-Questionnaire (EDE-Q) factor structures in men have been restricted to non-clinical settings, limiting conclusions about the factorial validity in men with eating disorders (ED). This study aimed to examine the factor structure of the German EDE-Q in a clinical group of adult men with diagnosed ED. METHODS ED symptoms were assessed using the validated German version of the EDE-Q. Exploratory factor analysis (EFA) using principal-axis factoring based on polychoric correlations was conducted for the full sample (N = 188) using Varimax-Rotation with Kaiser-Normalization. RESULTS Horn's parallel analysis suggested a five-factor solution with an explained variance of 68%. The EFA factors were labeled "Restraint" (items 1, 3-6), "Body Dissatisfaction" (items 25-28), "Weight Concern" (items 10-12, 20), "Preoccupation" (items 7 and 8), and "Importance" (items 22 and 23). Items 2, 9, 19, 21, and 24 were excluded due to low communalities. CONCLUSIONS Factors associated with body concerns and body dissatisfaction in adult men with ED are not fully represented in the EDE-Q. This could be due to differences in body ideals in men, e.g., the underestimation of the role of concerns about musculature. Consequently, it may be useful to apply the 17-item five-factor structure of the EDE-Q presented here to adult men with diagnosed ED.

Abstract
OBJECTIVE Phenotypical comparisons between individuals with obesity without binge eating disorder (OB) and individuals with obesity and comorbid binge eating disorder (OB + BED) are subject to ongoing investigations. At the same time, gender-related differences have rarely been explored, raising the question whether men and women with OB and OB + BED may require differently tailored treatments. METHOD We retrospectively compared pre- versus post-treatment data in a matched sample of n = 180 men and n = 180 women with OB or OB + BED who received inpatient treatment. RESULTS We found that men displayed higher weight loss than women independent of diagnostic group. In addition, men with OB + BED showed higher weight loss than men with OB after 7 weeks of treatment. CONCLUSIONS The present findings add to an emerging yet overall still sparse body of studies comparing phenotypical features and treatment outcomes in men and women with OB and OB + BED; implications for further research are discussed. CLINICAL TRIAL REGISTRATION The study was prospectively registered with the German Clinical Trial Register as part of application DRKS00028441.

Abstract
OBJECTIVE One of the most widely used assessment tools for disordered eating attitudes and behaviors, the Eating Disorder Examination Questionnaire (EDE-Q), has not yet been evaluated in Brazilian cisgender gay and bisexual men-an at-risk population given the extent of minority stressors in Brazilian culture. The present study aimed to assess the psychometric properties of the EDE-Q among Brazilian cisgender gay and bisexual adult men. METHOD The Brazilian EDE-Q was administered to a sample of 1409 gay and bisexual adult men, along with measures of self-objectification, body-ideal internalization, drive for muscularity, muscle dysmorphia symptoms, and body appreciation. The factor structure of the Brazilian EDE-Q was assessed using a two-step, split-sample exploratory (EFA; n = 704) and confirmatory factor analytic approach (CFA; n = 705). Additionally, convergent validity, internal consistency, and 2-week test-retest reliability were assessed. RESULTS Findings from an EFA and CFA revealed a one-factor structure with 22 items and adequate internal consistency (ω = .92, 95% CI = [.91, .93]). Moreover, the scale demonstrated good 2-week test-retest reliability (ICC = .86, 95% CI = [.82, .88], p < .001). The EDE-Q scores showed positive associations with self-objectification, body-ideal internalization, muscle dysmorphia symptoms, and drive for muscularity, as well as a negative association with body appreciation. DISCUSSION Results provide support for the use of the EDE-Q using a one-factor structure in Brazilian cisgender gay and bisexual adult men and give insights for future studies on eating disorders in sexual minorities in Latin America. PUBLIC SIGNIFICANCE The Eating Disorder Examination Questionnaire (EDE-Q) is one of the most widely used self-report measures of eating disorder symptoms. However, there is a lack of research on the validity and reliability of the EDE-Q in Latin American countries. This study evaluated the validity and reliability of the EDE-Q in Brazilian cisgender gay and bisexual adult men. Our findings give insights for future studies on eating disorders in sexual minorities in Latin America.

Abstract
BACKGROUND Psychotic disorders and eating disorders are complex mental illnesses associated with increased mortality and functional impairment. This study aimed to investigate the co-occurrence and relationships between eating disorders and psychotic disorders and assess the mediation effect of mood instability. METHODS This study used data from the Adult Psychiatric Morbidity Survey (APMS) 2014, a general population-based survey in England. Participants (total N = 7546, female N = 4488, male N = 3058, mean age = 52.3 years) were categorised based on psychotic disorder status into the groups of probable psychosis, diagnosed psychosis, and healthy controls without psychosis. The dependent variable of this study was the presence or absence of an eating disorder, with mood instability as the mediator. Logistic regression and mediation analyses were conducted to assess the relationships between these variables. RESULTS Both probable and diagnosed psychoses were significantly related to the presence of an eating disorder, and mood instability was found to be a mediating variable with moderate effect. CONCLUSION The present study demonstrates a significant relationship between eating disorders and psychotic disorders in the English general population, indicating higher levels of co-occurrence between these two groups of disorders than when compared with healthy controls. The findings also suggest the relationship between eating and psychotic disorders is mediated, to an extent, by the presence of mood instability traits. Future research could extend the present study's findings through assessing whether specific eating disorders are more significantly related to psychotic disorders than others.

Abstract
BACKGROUND The Eating Disorder Examination Questionnaire (EDE-Q) is a frequently used scale to evaluate eating behaviors and attitudes. In recent years, its use has increased due to the fact that the use of short forms is more practical. The aim of this study was to validate the short Turkish form of the Eating Disorder Examination Questionnaire (EDE-Q) including 13 items. METHODS The study included 924 adults at a mean age of 30.3 ± 10.93 years. EDEQ-13 was translated and adapted to Turkish according to the Beaton Guidelines. The Eating Attitudes Test-26 (EAT-26), the Satisfaction with Life Scale (SWLS), and the Body Appreciation Scale (BAS) were used to analyze their relationships to EDE-Q-13. RESULTS In this study, the rate of the total variance explained by the factors of EDE-Q-13 according to the Explanatory Factor Analysis (EFA) results of the scale was 83.54%. The Cronbach's alpha value of the scale was 0.89, and the Cronbach's alpha values of the 5 subscales were calculated in the range of 0.75-0.94. The criterion validity analysis showed an acceptable correlation between EDE-Q-13 and EAT-26, SWLS, and BAS. The confirmatory factor analysis (CFA) revealed that the model had fit values that were acceptable or good. CONCLUSION Both EFA and CFA results showed that it is appropriate to use the Turkish EDE-Q-13. EDE-Q-13 was significantly correlated with eating disturbances, body appreciation, and life satisfaction. In conclusion, the Turkish version of EDE-Q-13 possesses high levels of validity and reliability.
