Abstract
Restrained eating is becoming widespread recently. The present study aimed to examine whether peer appearance teasing was positively associated with restrained eating among Chinese adolescent girls and whether this association was mediated by fear of negative appearance evaluation (FNAE) and body surveillance. A sample of 720 Chinese adolescent girls completed questionnaires on peer appearance teasing, FNAE, body surveillance, and restrained eating. Peer appearance teasing was significantly and positively related to girls' restrained eating. FNAE mediated the relationship between peer appearance teasing and restrained eating. Furthermore, the association between peer appearance teasing and restrained eating was sequentially mediated by FNAE and body surveillance. The findings of this study provide new insights into the development of restrained eating among adolescent girls, and highlight peer appearance teasing and body surveillance as potential targets for intervention programs regarding body image concerns and eating disorders.

Abstract
Intuitive eating has been found to protect against disordered eating and preserve well-being. Yet, there are methodological (length), conceptual (inconsideration of medical, value-based, and access-related reasons for food consumption), and psychometric (item wording) concerns with its most common measure, the Intuitive Eating Scale-2 (IES-2). To address these concerns, we developed the IES-3 and investigated its psychometric properties with U.S. community adults. Across three online studies, we evaluated the IES-3's factorial validity using exploratory factor analysis (EFA; Study 1; N = 957; Mage = 36.30), as well as confirmatory factor analysis (CFA), exploratory structural equation modeling (ESEM), bifactor-CFA, and bifactor-ESEM (Study 2; N = 1152; Mage = 40.95), and cross-validated the optimal model (Study 3; N = 884; Mage = 38.54). We examined measurement invariance across samples and time, differential item functioning (age, body mass index [BMI], gender), composite reliability, and validity. Study 1 revealed a 12-item, 4-factor structure (unconditional permission to eat, eating for physical reasons, reliance on hunger and satiety cues, body-food choice congruence). In Study 2, a bifactor-ESEM model with a global intuitive eating factor and four specific factors best fit the data, which was temporally stable across three weeks. This model also had good fit in Study 3 and, across Studies 2 and 3, and was fully invariant and lacked measurement bias in terms of age, gender, and BMI. Associations between latent IES-3 factors and age, gender, and BMI were invariant across Studies 2 and 3. Composite reliability and validity (relationships with disordered eating, embodiment, body image, well-being, and distress; negligible relationship with impression management) of the retained model were also supported. The 12-item IES-3 demonstrates strong psychometric properties in U.S. community adults. Research is now needed using the IES-3 in other cultural contexts and social identity groups.

Abstract
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. Thus, the present study used a psychometric network approach to evaluate the psychometric properties of the IES-2 in Chinese adults from the general population. A sample of 700 Chinese general adults (50% women; Mage = 31.13 years, SD = 9.19) recruited online were included in the present study. Psychometric network analysis was performed. Exploratory graph analysis (EGA) identified four dimensions, which were well separated in the estimated network. The network structure showed excellent stability and metric measurement invariance (i.e., network loadings) across men and women. Furthermore, several items on the IES-2 were identified as key nodes in the network of the IES-2 that may be important for the development and maintenance of intuitive eating. For example, two items (i.e., "I trust my body to tell me when to eat," and "I trust my body to tell me when to stop eating") related to reliance on body cues were the most impactful nodes in the complete network. The findings of our study provide a greater understanding of the IES-2 from the perspective of network analysis and have implications for applications of intuitive eating interventions for general populations.

Abstract
PURPOSE To evaluate the association between intuitive eating and health outcomes in patients with type 2 diabetes in a cross-sectional study. METHODS Consecutively, outpatients attending at university hospital underwent clinical, laboratory, lifestyle, and eating behavior evaluations. Intuitive eating was assessed using the Intuitive Eating Scale-2 (IES-2), and the Three Factor Eating Questionnaire-21 was adopted as a confirmatory tool for disordered eating behavior. Optimized health outcomes were considered according to the American Diabetes Association criteria for BMI, HbA1c, lipid profile, and blood pressure values, and the International Diabetes Federation criteria for waist circumference. Considering the answers of the IES-2 items, patients were grouped by latent class analysis, and their characteristics were compared by appropriate tests. RESULTS In total, 267 patients were evaluated: 62.2% women, with 60 (53-65) years, BMI 31.9 ± 5.4 kg/m², diabetes duration of 16 ± 9 years, HbA1c 8.5 ± 1.5%, and an IES-2 total score of 58 (50-67)%. Three intuitive eating groups were identified: higher intuitive eating, nonemotional-oriented coping, and lower intuitive eating. Patients with higher intuitive eating have higher chances of having optimized BMI and serum triglycerides values compared to patients with lower intuitive eating. Also, the 10-point increase on IES-2 was associated with a 0.62 kg/m² reduction on BMI values (95%CI -1.18;-0.06), 1.90 cm on waist circumference (95%CI -3.26;-0.54), and 23 mg/dL in serum triglycerides values (95%CI -38.27;-7.40) after adjustment for age, sex, psychotropic drug use, medication effect score, smoking, and BMI. CONCLUSION Intuitive eating seems to be associated with optimized health outcomes and may contribute to better personalized interventions in nutritional treatment that promote adaptive behaviors in diabetes management, but should be tested.

Abstract
Background: The Dutch Eating Behavior Questionnaire (DEBQ) is a widely used self-report measure of eating styles, i.e., emotional, restrained, and external. A short and reliable version is useful for screening, routine assessments, and multipurpose surveys. Objective: The short version of the DEBQ by Bailly et al. (2012) was validated in the Italian context in two studies. Concurrent criterion validity was tested by considering gender, body mass index, self-esteem, eating self-efficacy, and snacking habits. Method: Data were collected via online questionnaires administered to two convenience samples of university students (n = 613, n = 856). Results: The three-factor structure of the short version of the DEBQ was supported and was invariant across genders. Correlations among the three eating styles, gender, body mass index, self-esteem, eating self-efficacy, and snacking habits followed the expected pattern. Conclusion: The short form of the DEBQ is psychometrically sound and can be used to investigate eating styles among Italian university students.

Foods 2023; 13:52.

Abstract
This study aimed to investigate the role of the psychological impact of environments rich in palatable foods on three aspects of eating behavior: cognitive restraint (CR), uncontrolled eating (UE), and emotional eating (EE). The hypotheses were as follows: (a) The psychological impact (i.e., motivation to eat) of an environment rich in palatable foods will positively predict CR, UE, and EE; (b) dieting will predict CR, UE, and EE; and (c) CR, UE, and EE will positively predict body mass index (BMI). This study had a cross-sectional design in which data were collected online from 413 subjects. The psychological impact of food-rich environments (food available, food present, and food tasted) was assessed using the Power of Food Scale (PFS), and CR, UE, and EE were assessed using the Three-Factor Eating Questionnaire (TFEQ-R18). Both instruments were tested for confirmatory factor analysis. The relationship between constructs was measured using partial least-square structural equation modeling (PLS-SEM). "Food available" positively predicted all TFEQ-R18 factors (p < 0.01). "Food present" positively predicted UE (p < 0.001) and EE (p = 0.01). People currently on a diet showed higher levels of CR (p < 0.001) and EE (p = 0.02). UE and EE positively predicted BMI. Thus, CR, UE, and EE were positively predicted by the motivation to consume palatable foods in varying proximity, suggesting that the presence of food and, more importantly, its general availability may be important determinants of eating behavior, particularly UE and EE. Health strategies should consider the influence of the food environment to prevent and better manage impairments in eating behavior. Sex differences suggest that special attention should be paid to women. Furthermore, dieting was associated with higher levels of EE, which in turn was associated with higher BMI. Weight loss interventions should consider this vulnerability.

Abstract
Although intuitive eating (IE) has become an increasingly adopted intervention target, current conceptualisations of IE have yet to pivot away from (neuro)normative physiology and phenomenology. Autistic individuals commonly report disordered eating behaviours and/or poorer well-being but appear to benefit from adaptive interventions using an affirmative approach. This article uses autism as a case example to summarise challenges related to IE's prevailing conceptualisation, before proposing how future research and current practice can be extended to the autistic population. Scholars are encouraged to evaluate the full 10-principal IE framework while utilising a participatory-led approach. We argue that research using a mixed methods design is urgently needed to comprehensively explore the (re)conceptualisation of IE in autistic people. While IE shows promise for producing positive outcomes in the autistic population, we discuss the potential challenges for research and practice due to its current emphasis on accurate interoception, emotional awareness and processing, and executive functioning. This suggests the need for research and practice to integrate autistic needs and experiences into future developments with an affirmative approach. Public Significance: IE is an effective intervention for reducing disordered eating behaviours. Autistic individuals commonly present disordered eating behaviours and have unique nutritional needs which often require intervention. However, there is limited understanding of IE among the autistic population. Research-informed definitions involving autistic perspectives will support translating the IE framework to this underrepresented population.

Abstract
A weight-inclusive approach to health involves the promotion of intuitive eating, i.e., the individual's ability to be aware of their physiological hunger and satiety cues to determine when and how much to eat, while paying attention to how certain foods affect their body. The second version of the Intuitive Eating Scale (IES-2) evaluates four interrelated traits of intuitive eating: Unconditional Permission to Eat (UPE), Eating for Physical rather than emotional Reasons (EPR), Reliance on internal Hunger/Satiety Cues (RHSC), and Body-Food Choice Congruence (BFCC). In this study, our aim was to evaluate the psychometric properties of a Mexican Spanish adaptation of the IES-2 for pregnant women and examine the relationship between intuitive eating traits and maternal sociodemographic characteristics. A sample of 514 pregnant women answered our IES-2 adaptation and a sociodemographic questionnaire. We determined the quality, validity, and reliability of our adaptation through descriptive measures, frequency distributions, intra-class correlations, and extreme answer group comparison for each item, eliminating those with weak technical properties. We then performed an exploratory principal component analysis and a confirmatory factor analysis. Last, we analyzed the association between intuitive eating and maternal sociodemographic and reproductive variables through correlation tests and multivariable linear regressions. Psychometric tests confirmed the validity and reliability of our IES-2 adaptation, which comprised 18 out of the 23 original items. Notably, both the exploratory and confirmatory factor analyses yielded not four but five factors, due to the EPR subscale splitting in two (the "emotional" and "physical" components of EPR). We attribute this novel finding to the emotional manifestations that naturally accompany pregnancy, which may incline pregnant women to base their eating behaviors more on the emotional than the physical component that would otherwise dominate their EPR trait. Further research is also needed about the UPE subscale during pregnancy, due to item removal and subtle changes in meaning. Finally, the influence of sociodemographic variables on the IES-2 score was extremely low, suggesting that other variables, possibly of a psychological nature, may have greater influence on a pregnant woman's intuitive eating.

Abstract
Disordered eating poses a significant risk to psychological and physical health. The experience of childhood trauma has been linked to the development of disordered eating behaviours, but the causal psychological mechanisms remain unclear. The metacognitive model holds promise as a potential framework for understanding the mediating psychological processes that explain how childhood trauma may lead to disordered eating. The purpose of this study was to examine the role of metacognitive beliefs mediating the relationship between childhood trauma and disordered eating behaviours. Adults from the Australian community (N = 461) completed an online self-report survey measuring childhood maltreatment (Childhood Trauma Questionnaire - Short Form), disordered eating behaviour (Three Factor Eating Questionnaire - Revised 21), and metacognitive beliefs (Metacognitive Questionnaire 30). Hierarchical multiple regression analyses revealed no independent associations between any forms of childhood maltreatment and cognitive restraint, while childhood emotional abuse was uniquely associated with uncontrolled eating and emotional eating. Through bootstrapping tests, the mediating effect between childhood trauma and uncontrolled and emotional eating consistently involved the metacognitive beliefs that thoughts are uncontrollable and dangerous. Future longitudinal research is required to confirm causal relationships.
