Abstract: Eating disorders are associated with significant illness burden and costs, yet access to evidence‐based care is limited. Greater use of programme‐led and focused interventions that are less resource‐intensive might be part of the solution to this demand‐capacity mismatch. In October 2022, a group of predominantly UK‐based clinical and academic researchers, charity representatives and people with lived experience convened to consider ways to improve access to, and efficacy of, programme‐led and focused interventions for eating disorders in an attempt to bridge the demand‐capacity gap. Several key recommendations were made across areas of research, policy, and practice. Of particular importance is the view that programme‐led and focused interventions are suitable for a range of different eating disorder presentations across all ages, providing medical and psychiatric risk are closely monitored. The terminology used for these interventions should be carefully considered, so as not to imply that the treatment is suboptimal. Programme‐led and focused interventions are a viable option to close the demand‐capacity gap for eating disorder treatment and are particularly needed for children and young people. Work is urgently needed across sectors to evaluate and implement such interventions as a clinical and research priority.

Abstract: Despite a wide range of proposed risk factors and theoretical models, prediction of eating disorder (ED) onset remains poor. This study undertook the first comparison of two machine learning (ML) approaches [penalised logistic regression (LASSO), and prediction rule ensembles (PREs)] to conventional logistic regression (LR) models to enhance prediction of ED onset and differential ED diagnoses from a range of putative risk factors. Data were part of a European Project and comprised 1402 participants, 642 ED patients [52% with anorexia nervosa (AN) and 40% with bulimia nervosa (BN)] and 760 controls. The Cross-Cultural Risk Factor Questionnaire, which assesses retrospectively a range of sociocultural and psychological ED risk factors occurring before the age of 12 years (46 predictors in total), was used. All three statistical approaches had satisfactory model accuracy, with an average area under the curve (AUC) of 86% for predicting ED onset and 70% for predicting AN v. BN. Predictive performance was greatest for the two regression methods (LR and LASSO), although the PRE technique relied on fewer predictors with comparable accuracy. The in idual risk factors differed depending on the outcome classification (EDs v. non-EDs and AN v. BN). Even though the conventional LR performed comparably to the ML approaches in terms of predictive accuracy, the ML methods produced more parsimonious predictive models. ML approaches offer a viable way to modify screening practices for ED risk that balance accuracy against participant burden.

Abstract: To assess the differences in comorbid lifetime and current substance use (tobacco, alcohol and drug use) between eating disorder (ED) patients and healthy controls in five different European countries. A total of 1664 participants took part in the present study. ED cases (n=879) were referred to specialized ED units in five European countries. The ED cases were compared to a balanced control group of 785 healthy in iduals. Participants completed the Substance Use Subscale of the Cross Cultural (Environmental) Questionnaire (CCQ), a measure of lifetime tobacco, alcohol and drug use. In the control group, also the GHQ-28, the SCID-I interview and the EAT-26 were used. ED patients had higher lifetime and current tobacco and general drug use. The only non-significant result was obtained for lifetime and current alcohol use. Significant differences across ED subdiagnoses and controls also emerged, with BN and AN-BP generally presenting the highest and AN-R and controls the lowest rates. The only exception was detected for alcohol use where EDNOS demonstrated the highest values. Only a few cultural differences between countries emerged. With the exception of alcohol consumption, tobacco and drug use appear to be more prevalent in ED patients than healthy controls. The differential risk observed in patients with bulimic features might be related to differences in temperament or might be the result of increased sensitivity to reward.

Abstract: The objective of this article was to examine lifestyle behaviours in eating disorder (ED) patients and healthy controls. A total of 801 ED patients and 727 healthy controls from five European countries completed the questions related to lifestyle behaviours of the Cross-Cultural Questionnaire (CCQ). For children, the ED s le exhibited more solitary activities (rigorously doing homework [p .001] and watching TV [p .05] and less socializing with friends [p .05]) than the healthy control group and this continued in adulthood. There were minimal differences across ED sub-diagnoses and various cross-cultural differences emerged. Reduced social activities may be an important risk and maintaining factor for ED symptomatology.

Abstract: To explore the psychometric properties of the Cross-Cultural Questionnaire (CCQ), a new self-report tool for assessing factors of risk and maintenance for eating disorders (ED). Data was collected during a multi-centre case-control study. The s le included 854 ED patients and 784 healthy participants from the UK, Spain, Austria, Slovenia and Italy. Exploratory factor analyses examined the factor structure of each section of the CCQ, and Cronbach's alpha coefficients valued the internal consistency of each derived scale score. Logistic regression and receiver operating characteristic (ROC) curve procedure assessed the screening accuracy and predictive validity of the empirical factors. Based on a total of 127 items, nine dimensions emerged, with satisfactory internal consistency and high congruence between countries. CCQ scores demonstrated satisfactory accuracy for discriminating between ED cases and controls (area under the ROC curve = 0.88). Most of the items achieved discriminative accuracy. This study offers preliminary evidence that the CCQ, available in five languages, is a useful and valid tool to assess factors of risk and maintenance for EDs.

Abstract: To compare the importance given to self/other standards by eating disorder (ED) patients and healthy controls. A total of 392 in iduals (240 consecutively referred and 152 healthy controls) took part in this study. All subjects were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria and were female patients. Participants completed the Family Style, Self-Expectations and Emotional related subscales of the Cross-Cultural Questionnaire. Three domains (namely, family standards, self-achievement and physical appearance) were associated with ED. Family standards scores discriminated for the presence of an ED (area under receiver operating characteristic curve equals 0.89), the main predictors being a higher level of importance of physical appearance (p < .001), family standards (p = .029) and conflicts with parents about physical appearance (p < .001). Higher self-standards, in physical appearance, were more relevant in bulimia nervosa and ED not otherwise specified, whereas higher family standards were more associated with anorexia nervosa. High self-standards and social standards are common features in ED. The parallelism that ED may establish between reaching them and their life success may have a crucial role as a developing and maintaining factor in ED.

Abstract: Research has indicated that in iduals with obesity have neurocognitive deficits, especially in cognitive flexibility that may in turn impact on their weight loss and maintenance. Consequently, we examined the efficacy of a manualised face-to-face cognitive remediation therapy for obesity (CRT-O) within a randomised controlled trial, in terms of improving cognitive flexibility, reducing binge eating behaviour, improving quality of life and helping with weight loss. 80 adults with obesity (body mass index >30 kg/m Mixed-effects model analyses revealed that the CRT-O group had a significant improvement in their cognitive flexibility at post-treatment and 3-month follow-up compared to the control group (Cohen's d = 0.96 to 2.1). 68% of those in the CRT-O group achieved a weight loss of 5% or more at follow-up compared to only 15% of the controls (Cohen's d = 1.3). Changes in set-shifting predicted changes in weight (p < .05). Binge eating reduced in the CRT-O group compared to the control (Cohen's d = 0.80). This is the first study showing the efficacy of CRT-O for obesity. Future CRT-O studies with longer follow-ups and pairing it with longer BWL programs are needed. 12613000537752. 14 May 2013.

Abstract: The objective of this study was to examine whether there is an association between in idual and family eating patterns during childhood and early adolescence and the likelihood of developing a subsequent eating disorder (ED). A total of 1664 participants took part in the study. The ED cases ( n 879) were referred for assessment and treatment to specialized ED units in five different European countries and were compared to a control group of healthy in iduals ( n 785). Participants completed the Early Eating Environmental Subscale of the Cross-Cultural (Environmental) Questionnaire, a retrospective measure, which has been developed as part of a European multicentre trial in order to detect dimensions associated with ED in different countries. In the control group, also the General Health Questionnaire-28 (GHQ-28), the semi-structured clinical interview (SCID-I) and the Eating Attitudes Test (EAT-26) were used. Five in idually Categorical Principal Components Analysis (CatPCA) procedures were adjusted, one for each theoretically expected factor. Logistic regression analyses indicated that the domains with the strongest effects from the CatPCA scores in the total s le were: food used as in idualization, and control and rules about food. On the other hand, healthy eating was negatively related to a subsequent ED. When differences between countries were assessed, results indicated that the pattern of associated ED factors did vary between countries. There was very little difference in early eating behaviour on the subtypes of ED. These findings suggest that the fragmentation of meals within the family and an excessive importance given to food by the in idual and the family are linked to the later development of an ED.
