Objectification theory posits that self-objectification can lead to disordered eating, with significant positive correlations between self-objectification and eating disorder (ED) psychopathology found in women in both clinical and non-clinical samples. Maladaptive rumination is another process frequently associated with EDs, but its relationship with self-objectification and ED psychopathology needs further investigation. Our aim was to conduct a preliminary test to investigate whether maladaptive rumination mediated the relationship between self-objectification and ED psychopathology in women. Data were collected online from a general community sample of 243 women. Correlation and mediation analyses were undertaken. Significant positive associations were found between rumination, self-objectification, and ED psychopathology. Rumination significantly mediated the relationship between self-objectification and ED psychopathology, accounting for 20.52% of the variance, suggesting that a greater tendency to ruminate may contribute to ED vulnerability in those with high self-objectification. These preliminary findings may inform assessment and formulation of women presenting with ED psychopathology in addition to supporting psychological interventions (e.g. CBT or acceptance-based approaches), which can target both self-objectification and rumination processes. Future research involving replication with clinical samples is warranted to corroborate the relationship between these constructs, their impact on ED psychopathology over time and to investigate their utility in assessment and treatment approaches.

Subjective eating disorder (ED) recovery has important clinical relevance. However, studies have focused on the perspectives of cisgender heterosexual individuals, which is notable given that sexual and gender minority (SGM) people often describe feelings misrepresented by prevailing ED conceptualizations. We examined eating pathology and psychosocial functioning across subjective recovery stages in SGM individuals (N = 196). Analyses of variance tested differences between active ED (n = 106, 54.1%), partial recovery (n = 82, 41.8%), and full recovery (n = 8, 4.1%) groups. Groups differed in body dissatisfaction, binge eating, restricting, clinical impairment, autonomy, environmental mastery, and self-acceptance. Most differences were observed between the full recovery and active ED groups and the full recovery and partial recovery groups, such that subjectively higher levels of ED recovery were generally associated with lower transdiagnostic ED symptoms and better psychosocial functioning. Clinical profiles appear similar between SGM and cisgender heterosexual individuals across subjective ED recovery stages.

Anorexia nervosa (AN) is an eating disorder that is significantly associated with severely impaired physiological functions, multiple organ failure, and suicidal ideation. This study aims to estimate the global, regional, and national secular trends of AN burden based on Global Burden of Diseases (GBD) 2019 data. The pertinent data for AN were collected from the GBD Study 2019. The long-term trends of the burden of AN were analyzed in different Social Demographic Index (SDI) regions by Joinpoint regression, Age-Period-Cohort analysis, and the Estimated Annual Percentage Changes. This study found that the global burden of AN gradually increased over the past 30 years, with the highest burden remaining in high-income countries, but the biggest increasing trend was observed in Asian region. AN was more common in adolescents and young women, but it was growing rapidly in adolescents and young men. Disability-adjusted life years (DALYs) caused by AN was the highest in the age group of 15-24 years among all SDI levels. The risk of AN rapidly increased since the beginning of the twenty-first century apart from high SDI regions, and it was higher in later-born cohorts than the earlier ones in various SDI areas. Future studies could verify our findings by using individual-level data. Our findings could help policy makers around the world understand the burden of AN in their countries and develop appropriate health policies for prevention and early intervention for high-risk populations.

Purpose: The aim of this study was to map which instruments are currently being used to measure disordered eating in adolescent boys as part of a Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis.

Method: Utilizing the PRISMA review protocol, 174 journal articles were reviewed.

Results: Sixty-seven articles used versions of the Eating Attitudes Test to measure adolescent boys' disordered eating, 32 used versions of the Eating Disorder Examination-Questionnaire, 30 used versions of the Eating Disorder Inventory, 25 used SCOFF, and 10 used the Drive for Muscularity Scale. A plethora of other instruments for measuring disordered eating were utilized as well.

Conclusion: Studying adolescent boys' disordered eating by using instruments primarily developed and validated for girls may provide unreliable estimates of the numbers of boys who suffer from disordered eating, which would preclude early intervention. One strength of the reviewed studies was that several used multiple measurements to validate their results. One of the weaknesses was the lack of distinguishing genders among certain groups, such as athletes or patients. Among the opportunities identified was the possibility of expanding on research on the association between puberty and disordered eating, with sports and parents potentially acting as buffers against the onset of disordered eating. A clear threat to research on disordered eating among adolescent boys was the (in)accuracy of the measurements.

This study aimed to evaluate the efficacy of Acceptance and Commitment Therapy (ACT) in mitigating perceived stress, rumination, and distress tolerance among women diagnosed with Bulimia Nervosa (BN) in Ahvaz, Iran. A quasi-experimental pre-test-post-test design with a control group was employed. The target population consisted of all female BN patients referred to the Ahvaz Binge Eaters Association between February and May 2022. Patients were definitively diagnosed with BN by a clinical specialist using a structured clinical interview adhering to DSM-5 criteria. From an initial pool of 91 patients, 50 were randomly selected for participation and subsequently assigned to either the experimental or control group, with each group comprising 25 individuals. Pre-test analysis revealed no significant group differences in perceived stress, rumination, or distress tolerance among women with BN. However, post-test scores indicated a significant decrease in both perceived stress and rumination within the experimental group compared to the control group (p < .01). Furthermore, the post-test analysis demonstrated that ACT intervention significantly improved distress tolerance in women with BN (p < .01). These findings suggest that ACT may be a promising therapeutic approach for alleviating psychological distress and enhancing emotional regulation in individuals grappling with BN.

There is a notable overlap between autism and eating disorders (EDs), and autistic individuals may experience poorer ED treatment outcomes than non-autistic peers. To make meaningful change in this field, it is imperative that we actively engage in co-production of research, however there are currently no guidelines to support co-production with autistic people with eating disorders. This paper reports on best practice guidelines that were co-produced across a series of workshops bringing together autistic people with EDs, researchers, clinicians, third-sector organisations, and parents/carers. The guidelines are intended to be used as a foundation for future co-produced autism and ED research. By creating a trusted, ethical co-production relationship, we hope to generate more clinically meaningful and translatable research.

This study reports the outcome of a low intensity pre-treatment intervention (a guided e-health podcast) for patients with anorexia nervosa and bulimia nervosa, delivered between assessment and the start of the full outpatient treatment programme. A case series design was used. A total of 254 patients at a specialist eating disorder service were offered a pre-treatment three-week psychoeducational intervention (Keeping Myself Safe; KMS), and 203 undertook the intervention. The intervention consisted of six podcasts (107 mins), an accompanying workbook, and a follow-up review appointment. Body Mass Index and Eating Disorder Examination-Questionnaire scores were taken at assessment, end of the KMS intervention (mean duration = 21.9 days) and start of treatment (mean = 79.8 days post KMS intervention). Generalised Linear Mixed Models were used to test main and interaction effects (diagnosis x time). There were improvements on most variables following the KMS intervention. The effects were more pronounced for patients with bulimia nervosa across several measures. Pre-treatment guided e-health psychoeducational interventions can be associated with early attitudinal and behavioural change in patients with bulimia nervosa and anorexia nervosa whilst on the waiting list for treatment. They allow greater, affordable accessibility to effective psychoeducation and enhance potential engagement. More research is required to investigate the longer-term impact on retention and outcome, particularly in anorexia nervosa.

The Pica, ARFID, and Rumination Disorder ARFID Questionnaire (PARDI-AR-Q) and the Eating Disorders in Youth Questionnaire (EDY-Q) were developed to assess avoidant/restrictive food intake disorder (ARFID), but research is ongoing regarding their discriminant validity. This study examined scores of adult inpatients with ARFID or anorexia nervosa, restricting type (AN-R) on the PARDI-AR-Q, EDY-Q, and Eating Disorder Examination Questionnaire (EDE-Q) at admission to a medical stabilization unit for severe eating disorders. Response differences between 78 adult inpatients with ARFID or AN-R were analyzed using a two-sample t-test or Fisher's exact test. Sensitivity and specificity of self-report measures were examined using receiver operating characteristic curves. Patients with AN-R had significantly higher severity of impact and lower concern about aversive consequences scores than patients with ARFID on the PARDI-AR-Q (p < .001), with no significant differences on sensory-based avoidance or lack of interest or EDY-Q total score. Patients with AN-R scored significantly higher on all domains of the EDE-Q (p's < .001) and the EDE-Q subscales had better discrimination than ARFID measures. This study provides further evidence of the need for assessments that can distinguish ARFID from AN, and may also highlight the need for future research on the nosological accuracy of differentiating these disorders.

To date, little data exist about the stability of networks, which is an important limitation given the interest in applying network approaches for evaluating and informing treatment and intervention. Thus, the aim of the present study was to examine the stability of the eating disorder symptom network in a clinical eating disorder sample across two timepoints, on average 18 months apart. The sample included 99 eating disorder patients from a transdiagnostic sample. Findings from network analyses revealed that the networks exhibited both structural and global strength invariance over time. These findings suggest that in this clinical transdiagnostic sample, some support for differences over time in the network structure and strength at the group level existed despite null formal invariance tests. These findings are consistent with the change in clinical presentations within the sample.
