Elevating the Field of Eating Disorders Through Scholarship and Thoughtfulness: Honoring the Legacy of Dr. Michael Strober.

This Virtual Issue of the International Journal of Eating Disorders honors the legacy of the late Dr. Michael Strober in the eating disorders and child psychiatry fields. Having served as Editor-in-Chief of the International Journal of Eating Disorders from 1983 to 2012, Dr.

Engagement in Intermittent Fasting is Prospectively Associated With Higher Body Mass Index, Higher Eating Disorder Psychopathology, and Lower Intuitive Eating in Chinese Adults.

Objective: This study examined cross-sectional and longitudinal associations of intermittent fasting (IF) engagement with body mass index (BMI), both thinness-oriented and muscularity-oriented eating disorder (ED) psychopathology, eating-related psychosocial impairment, and intuitive eating.

Method: Using a longitudinal design, 491 Chinese adults (M = 30.33 years, SD = 7.

Muscularity bias internalization moderates the associations of muscularity dissatisfaction with muscularity-oriented disordered eating and psychosocial well-being in men but not women.

Prior research demonstrates positive associations between muscularity dissatisfaction and an array of negative health outcomes, including muscularity-oriented disordered eating, eating-related psychosocial impairment, and psychological distress. However, muscularity dissatisfaction differs by gender and is not always linked to these outcomes, indicating the existence of moderators of these associations. We proposed and examined muscularity bias internalization (MBI) as a moderator of these associations.

Reported higher general early-life bullying victimization is uniquely associated with more eating pathology and poor psychosocial well-being in Chinese sexual minority men.

General early-life bullying victimization has been used as an early-life marker of eating and body image disturbances and poor psychosocial well-being later in life. We expand existing research in this area to Chinese sexual minority (SM) men, a vulnerable and under-researched subgroup, by considering associations of general early-life bullying victimization with current eating and body image disturbances and poor psychosocial well-being. We assessed demographics, general early-life bullying victimization, past appearance teasing, current thinness- and muscularity-oriented eating and body image disturbances, and current psychosocial well-being in Chinese SM men (N = 433).

Negative emotional eating patterns in Chinese adolescents: A replication and longitudinal extension with latent profile and transition analyses.

This study, which is a longitudinal extension of previous cross-sectional studies in Chinese and American college students and general adults (Dixit, He, Whited, Ellis, & Zickgraf, 2023; He, Chen, Wu, Niu, & Fan, 2020; Xu et al., 2024), used latent profile and latent transition analyses to investigate negative emotional eating patterns and the stability of these patterns in 1462 Chinese adolescents (41% boys, aged 11-17 years) at baseline and 18 months later. We also explored baseline demographic predictors of negative emotional eating patterns and the associations between these patterns and outcome variables measured 18 months later.

A Longitudinal Network Analysis of Emotion Regulation, Interpersonal Problems, and Eating Disorder Psychopathology in Chinese Adolescents.

Objective: The present longitudinal study examined sex-specific, symptom-level relationships among emotion regulation (ER), interpersonal problems (IP), and eating disorder (ED) psychopathology in a large sample of Chinese adolescents.

Method: Data were from a project with four waves of data collection (N = 1540; 710 boys and 830 girls) at 6-month intervals over 18 months. Questionnaires assessed ED psychopathology, ER, and IP at each wave of data collection.

Examining Food-Specific and General Inhibitory Control and Working Memory as Moderators of Relations Between Emotion Regulation Difficulties and Eating Pathology in Adults With Overweight/Obesity: A Preregistered, Cross-Sectional Study.

Objective: Empirical research and theory support the interaction of executive functions (e.g., inhibitory control, working memory) and emotion regulation in guiding goal-oriented behavior; however, applications to eating pathology (e.

Differences in Thinness- and Muscularity-Oriented Eating and Body Image Disturbances and Psychosocial Well-Being in Chinese Sexual Minority Men Reporting Top, Bottom, and Versatile Sexual Self-Labels.

In addition to describing sexual partner preferences, sexual self-labels in gay and bisexual (henceforth, sexual minority) men, such as top, bottom, and versatile, are associated with psychological characteristics (e.g., gendered personality traits).

A Call for More Culture-Based Research to Understand Body Dissatisfaction and Disordered Eating in Men: Commentary on Monocello et al. (2024).

Using culture-based approaches, Monocello et al. revealed that young Korean men generally shared the same perceptions of fatness, including three categories ("too thin," "balanced," and "too fat"). The "balanced" category was most consistent with local South Korean culture, and the "too fat" category was associated with higher body dissatisfaction and disordered eating.

Negative emotional eating patterns in general Chinese adults: A replication and expansion study examining group differences in eating disorder symptomatology, psychosocial impairment, and emotion regulation difficulties.

Previous research identified four patterns of negative emotional eating in American and Chinese university students and proposed future directions (e.g., exploring potential differences in emotion regulation across patterns and replicating the patterns in a general, non-student population).

Exploring the moderating roles of dispositional mindfulness and body image flexibility in the association between body dissatisfaction and disordered eating in Chinese adolescents.

Objectives: Previous research suggests potential moderating roles of dispositional mindfulness and body image flexibility in the association between body dissatisfaction and disordered eating. However, relevant research is mainly conducted on adult women from Western countries, and limited evidence exists for adolescent samples, especially from non-Western contexts (e.g.

Introducing Diagnostic Classification Modeling as an Unsupervised Method for Screening Probable Eating Disorders.

Screening for eating disorders (EDs) is an essential part of the prevention and intervention of EDs. Traditional screening methods mostly rely on predefined cutoff scores which have limitations of generalizability and may produce biased results when the cutoff scores are used in populations where the instruments or cutoff scores have not been validated. Compared to the traditional cutoff score approach, the diagnostic classification modeling (DCM) approach can provide psychometric and classification information simultaneously and has been used for diagnosing mental disorders.

The relation between questionnaire-measured self-reported emotional eating and disordered eating behaviors: A meta-analysis of nearly three decades of research.

Extensive research exists on the association between self-reported emotional eating (EE) and disordered eating (DE) behaviors. Heterogeneity exists by type (e.g.

Self-objectification in Chinese pregnant women: The mixed role of functionality appreciation.

Extensions of objectification theory to pregnant women are few and continued research is needed to better understand the psychological consequences of significant changes to physical appearance during pregnancy. Specific interests in this area include functionality appreciation which may be particularly relevant to pregnancy. Research in this area is also lacking representation of non-Western cultural contexts.

Exploring the associations between muscularity teasing and eating and body image disturbances in Chinese men and women.

This study described muscularity teasing in both men and women and explored its associations with eating and body image disturbances in adults from China. A total of 900 Chinese adults (50% women) were recruited online. Correlation and regression analyses were conducted to examine the relationships between muscularity teasing and a battery of measures on eating and body image disturbances.

Psychometric network analysis of the Intuitive Eating Scale-2 in Chinese general adults.

The Intuitive Eating Scale-2 (IES-2) is a measure of intuitive eating behaviors that has been extensively validated, with traditional latent variable modeling approaches, in youth and adults from many different populations, including college students in China. However, there is still a lack of research on the psychometric properties of the IES-2 in adults from the Chinese general population. Moreover, psychometric network analysis, as a complement to traditional latent variable modeling approaches, has not been used for examining the psychometric properties of the IES-2.

Translation and validation of a Chinese version of the Appearance Schemas Inventory-Revised in Chinese adults.

The current study translated the Appearance Schemas Inventory-Revised (ASI-R) into Chinese (Mandarin) and examined its psychometric properties in Chinese adult women and men. Sample 1 included 400 women and 400 men to examine the factor structure of the ASI-R with exploratory factor analysis (EFA). Sample 2 involved 300 women and 300 men, and the EFA-derived factor structures in Sample 1 of the ASI-R were examined with exploratory structural equation modeling (ESEM), bifactor ESEM (B-ESEM), and bifactor ESEM with correlated uniqueness for negatively worded items (B-ESEM-CU) for both women and men.

Exploring the prospective relationships between food addiction symptoms, weight bias internalization, and psychological distress in Chinese adolescents.

Objective: Relationships exist between food addiction symptoms, weight bias internalization, and psychological distress, yet previous research is primarily cross-sectional with adults from Western contexts. We examined the prospective relationships between food addiction symptoms, weight bias internalization, and psychological distress in Chinese adolescents.

Methods: Over three time points (Time 1, baseline; Time 2, 6-months; Time 3, 12-months) spanning 1 year, we examined cross-sectional and bi-directional relationships between food addiction symptoms, weight bias internalization, and psychological distress in Chinese adolescents (N = 589; aged 14-18 years at baseline).

Validation of the Muscularity Bias Internalization Scale in Chinese women.

The Muscularity Bias Internalization Scale (MBIS) captures an individual's endorsement of stereotypical beliefs about muscularity and engagement in self-stigmatizing evaluations about their muscularity. The MBIS has been validated in Chinese men and Lebanese men and women, showing strong internal consistency reliability and construct validity. Because muscularity-related body image concerns are present in Chinese women, there is a need for research to validate the MBIS in Chinese women.

Higher meal disengagement and meal presentation are uniquely related to psychological distress and lower quality of life in undergraduate students.

Picky eating, which occurs in emerging adulthood and is associated with psychological distress and quality of life, has historically been conceptualized as unidimensional despite research suggesting it is a multifaceted construct. An undergraduate sample ( = 509; = 19.96).
