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., China). Thus, this study aimed to examine the moderating roles of dispositional mindfulness and body image flexibility in the relationship between body dissatisfaction and disordered eating in Chinese adolescents. METHOD: We recruited 545 Chinese adolescents (53.9% boys, aged 12-16 years) who completed measures of body dissatisfaction, dispositional mindfulness, body image flexibility, and disordered eating. Moderation analyses were examined with PROCESS macro on SPSS. RESULTS: In separate models, both higher dispositional mindfulness and body image flexibility weakened relationships between body dissatisfaction and disordered eating. However, when both dispositional mindfulness and body image flexibility were entered into the same moderation model, only body image flexibility showed a significant moderating effect. DISCUSSION: Both dispositional mindfulness and body image flexibility may weaken the association between body dissatisfaction and disordered eating in adolescents. However, body image flexibility might have a stronger effect than dispositional mindfulness. These findings suggest that interventions aimed at reducing body dissatisfaction to prevent disordered eating in adolescents may pay more attention to adolescents' body image flexibility.

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. In the present study, we introduce DCM as an innovative and alternative approach to screening individuals at risk of EDs. To illustrate the practical utility of DCM, we provide two examples: one involving the application of DCM to examine probable ED status from the 12-item Short form of the Eating Disorder Examination-Questionnaire (EDE-QS) to screen probable thinness-oriented EDs and the Muscularity-Oriented Eating Test (MOET) to screen probable muscularity-oriented EDs.

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., unidimensional vs. multidimensional) and valence (e.g., negative vs. positive) of self-reported EE, and no previous meta-analyses have examined the association between self-reported EE and DE behaviors. A total of 67 studies (N = 26,289; 43 reporting relations in one model, and 24 reporting relations in more than one model) met inclusion criteria; ranges for age and publication date were 18.0-61.8 years old and 1995 to 2022. Five models quantified relations between DE behaviors and 1) broad negative EE, 2) EE in response to depression, 3) EE in response to anger and anxiety, 4) EE in response to boredom, and 5) EE in response to positive emotions. Using random-effects models, pooled Cohen's d effect sizes suggested small, positive relations between DE behaviors and self-reported broad negative EE (d = 0.40, p < 0.001), EE-depression (d = 0.41, p < 0.001), EE-anger/anxiety (d = 0.35, p < 0.001), and EE-boredom (d = 0.38, p < 0.001). A significant, but very small, positive relation was observed between DE behaviors and self-reported EE-positive (d = 0.08, p = 0.01). Subgroup analyses suggested a medium, positive relation between self-reported broad negative EE and binge eating (d = 0.53, p < 0.001) and a small, positive relation between self-reported broad negative EE and dietary restraint (d = 0.20, p < 0.001). Significant heterogeneity was identified across all models except for the EE-boredom and DE behaviors model. Higher BMI, but not age, clinical status, or type of DE behavior strengthened the positive relation between self-reported broad negative EE and DE behaviors. Findings support previous research suggesting that negative and positive EE are distinct constructs, with negatively valenced EE being more closely associated with DE behaviors, especially binge eating.

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. Gender differences in the associations were examined. Men reported more muscularity teasing than women (31.6% men vs. 15.6% women; χ2(1,N = 900) = 31.99, p < .001). Muscularity teasing was significantly and positively correlated with all measures in both men and women. Muscularity teasing explained significant, unique variance in all measures for men and women, except for body fat dissatisfaction in women, beyond covariates (i.e., age, body mass index, and weight teasing). The relationships between muscularity teasing and eating and body image disturbances were generally stronger in men than women. Findings further suggest that muscularity teasing is an important factor related to eating and body image disturbances in men and women, but muscularity teasing might be more detrimental to men's eating behaviors and body image. Future research is needed to further explore the directionality and mechanisms of the links between muscularity teasing and eating and body image disturbances.

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. To this end, we employed an online survey to assess objectification theory and functionality appreciation in Chinese pregnant women (N = 345). Correlations showed that higher body surveillance and body shame were associated with higher disordered eating and psychological distress, and higher functionality appreciation was associated with lower body surveillance, body shame, and disordered eating. Mediation analyses suggested that higher body surveillance was associated with higher body shame which, in turn, was associated with higher disordered eating and psychological distress. Main effects suggested a negative association between functionality appreciation and body shame, but moderation analyses suggested that higher functionality appreciation strengthened the positive association between body surveillance and body shame. Findings underscore objectification theory as a useful framework to understand eating and body image disturbances and psychological distress in Chinese pregnant women and outline future directions to clarify the temporal nature of these associations and the precise role of functionality appreciation.

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. 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.

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. Results of the EFA identified a 4-factor model in women and a 2-factor model in men. The B-ESEM-CU consistently showed the best model fit. In the B-ESEM-CU, the general factor was well-defined, but the specific factors were not, supporting the use of the global factor to conceptualize the ASI-R for Chinese women and men. Evidence of adequate internal consistency, test-retest reliability, and construct validity of the global factor of the ASI-R was suggested in both women and men. Findings suggest the ASI-R is a useful instrument to measure body image investment in Chinese women and men, specifically using the B-ESEM-CU to understand the dimensionality of the ASI-R.

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. The present study examined the factor structure and psychometric properties of the MBIS in a sample of Chinese women. Exploratory factor analysis (n = 300) identified a two-factor structure which showed adequate model fit in confirmatory factor analysis (n = 300), with χ2(76) = 294.63 (p < .001), CFI = 0.98, TLI = 0.98, and SRMR = 0.05. Results also showed that the MBIS in women had adequate internal consistency, two-week test-retest reliability, and good construct validity. Findings suggest that the MBIS is a useful tool for assessing muscularity bias internalization, a potentially important risk factor for muscularity-oriented eating and body image disturbances.

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). Pearson correlations and cross-lagged models examined the cross-sectional and longitudinal relationships between food addiction symptoms, weight bias internalization, and psychological distress. RESULTS: Cross-sectional correlations suggested positive relationships between food addiction symptoms, weight bias internalization, and psychological distress at each time point. Regarding bi-directional relationships, higher psychological distress was associated with both higher weight bias internalization and higher food addiction symptoms at the following time points. However, food addiction symptoms and weight bias internalization were not prospectively associated. Time 2 psychological distress did not significantly mediate the relationship between Time 1 weight bias internalization and Time 3 food addiction symptoms. DISCUSSION: Findings suggest no direct longitudinal link between food addiction symptoms and weight bias internalization and vice versa. However, findings do suggest that psychological distress is temporally associated with higher food addiction symptoms and weight bias internalization in Chinese adolescents. Targeting psychological distress may prove useful in treatments of food addiction symptoms and weight bias internalization in Chinese adolescents. PUBLIC SIGNIFICANCE: Positive associations exist between food addiction symptoms, weight bias internalization, and psychological distress, but findings are largely cross-sectional and bound to adult populations from Western contexts. Using a longitudinal design in Chinese adolescents, findings suggested that baseline psychological distress was associated with higher food addiction symptoms and higher weight bias internalization at follow-up time points. Treatments targeting psychological distress may be helpful in reducing food addiction symptoms and weight bias internalization in Chinese adolescents.

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

Objective: 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. Participants: An undergraduate sample (N = 509; Mage = 19.96). Methods: A cross-sectional survey assessed picky eating facets (food variety, meal disengagement, meal presentation, and taste aversion), disordered eating, anxiety, depression, stress, obsessive compulsive disorder (OCD), and social phobia symptoms, and quality of life. Results: Meal disengagement was uniquely related to higher anxiety, depression, stress, and social phobia symptoms and lower quality of life, whereas meal presentation was uniquely related to higher anxiety, stress, and OCD symptoms, beyond covariates and disordered eating. Food variety and taste aversion were not uniquely related to outcomes. Conclusions: Considering picky eating multidimensionally may yield important insights beyond the broader construct in terms of its relationship with psychological well-being in undergraduates.

Translation and validation of a Chinese version of the body talk scale for women and men.

Body talk has received increasing research attention in recent years, with accumulating evidence supporting the link between body talk and eating and body image disturbances. However, research on body talk in China is still relatively scarce and generally focused on fat talk, especially in women, and much remains unknown about muscle talk and positive body talk for both Chinese women and men. To promote a better understanding of body talk in the Chinese context, the present study adapted the Body Talk Scale (BTS) into Chinese Mandarin (i.e., C-BTS) and evaluated the factor structure and psychometric properties of the C-BTS in Chinese adult women and men. The English version of the BTS was translated into Chinese Mandarin with standard procedures. With 300 Chinese women (Mage = 29.48 years, SD = 7.26) and 300 men (Mage = 29.36 years, SD = 6.81), we examined the factor structure and gender invariance of the C-BTS, as well as internal consistency reliability, test-retest reliability, and construct validity, including convergent, concurrent, and incremental validity of the C-BTS. The results indicated that, consistent with the development study of the BTS, the C-BTS had three subscales (i.e., Negative Fat Talk, Negative Muscle Talk, and Positive Body Talk) and good reliability and validity. The findings demonstrate that the C-BTS can be a useful measure of body talk in both Chinese women and men.

The Body Talk Scale (BTS) measures three types of body talk, including negative fat talk, negative muscle talk, and positive body talk. The present study adapted the English version of the BTS into Chinese Mandarin and examined its psychometric properties in Chinese adult women and men. Results showed that the BTS had adequate reliability and validity in Chinese adults and could be used to assess body talk in Chinese women and men.

Screen use while eating is associated with lower intuitive eating and higher disordered eating in Chinese adult men and women.

OBJECTIVE: We aimed to explore the potential associations between screen use while eating and intuitive eating and disordered (thinness-oriented and muscularity-oriented) eating behaviors. METHODS: Analyses included 600 Chinese adults (50% women; Mage = 30.67, SD = 8.08) recruited online. The use of four major screen devices was captured, including cell phones, tablets, computers, and TVs. Three types of eating behaviors were examined, namely intuitive eating, thinness-oriented disordered eating, and muscularity-oriented disordered eating. Pearson correlation and hierarchical regression analyses were conducted separately for men and women to examine the sex-specific associations between screen use while eating and intuitive eating, thinness-oriented disordered eating, and muscularity-oriented disordered eating. RESULTS: In both men and women, more screen use while eating was significantly associated with lower intuitive eating, higher thinness-oriented disordered eating, and higher muscularity-oriented disordered eating, above and beyond total screen time and social media use. DISCUSSION: We found preliminary evidence for the significant links between screen use while eating and intuitive eating and disordered eating. Given the global increases in screen use, continued research is warranted to further explore the role of screen use while eating in the development and maintenance of intuitive eating and disordered eating. PUBLIC SIGNIFICANCE: Much remains unknown regarding screen use while eating and eating behaviors. We found that in both Chinese men and women, more screen use while eating was significantly and uniquely associated with lower intuitive eating, higher thinness-oriented disordered eating, and higher muscularity-oriented disordered eating. Findings highlight the importance of incorporating screen use while eating in future research on intuitive eating and disordered eating.

A network analysis of disordered eating symptoms, big-five personality traits, and psychological distress in Chinese adults.

OBJECTIVE: Previous studies have revealed associations between disordered eating symptoms, big-five personality traits, and psychological distress. However, limited research has explored these relationships as a network, including their interconnections, and even less has done so in non-Western populations. We employed network analysis to investigate the co-occurrence of disordered eating symptoms, big-five personality traits, and psychological distress in Chinese adults. METHOD: A sample of 500 Chinese adults (256 men) completed measures assessing big-five personality traits, psychological distress, and disordered eating symptoms. The network of personality traits, psychological distress, and disordered eating symptoms was estimated, including its central and bridge nodes. RESULTS: The central nodes in the network were the facets of openness (like adventure), extraversion (like going to social and recreational parties), and disordered eating symptoms (dissatisfaction with body weight or shape). Moreover, certain facets of neuroticism (always worrying something bad will happen), psychological distress (feeling worthless), and an inverse facet of extraversion (bored by parties with lots of people) were identified as essential bridge nodes in maintaining the structure of the network. CONCLUSION: Our findings suggest that personality traits (e.g., openness and extraversion) and body dissatisfaction are important in maintaining the network in a community sample of Chinese adults. While future replication is needed, findings from this study suggest that individuals with negative self-thinking, predisposed neuroticism, and extraversion may be at risk of developing disordered eating symptoms. PUBLIC SIGNIFICANCE: The present study contributes to existing knowledge by employing a network perspective to examine the associations between disordered eating symptoms, big-five personality traits, and psychological distress in a Chinese adult community sample. The identified facets of neuroticism and extraversion and symptoms of psychological distress may be worthy of targeting in the prevention and treatment of disordered eating in the Chinese context.

Examining an integrated sociocultural and objectification model of thinness- and muscularity-oriented disordered eating in Chinese older men and women.

OBJECTIVE: We tested an integrated model of three prominent theories of disordered eating (tripartite influence theory, objectification theory, and social comparison theory) in a sample of older Chinese men and women. METHOD: Chinese older men (n = 270) and women (n = 160) completed questionnaires assessing the tripartite influence, objectification, and social comparison theories and thinness- and muscularity-oriented disordered eating. Two structural equation models were tested in Chinese older men and women. RESULTS: The integrated model showed good model fit and described meaningful variance in thinness- and muscularity-oriented disordered eating in Chinese older men and women. Higher appearance pressures were uniquely related to higher muscularity-oriented disordered eating in men. Across both gender groups, higher thinness internalization was uniquely related to higher thinness- and muscularity-oriented disordered eating, and in women only, higher muscularity internalization was uniquely related to lower thinness-oriented disordered eating. In men, higher upward and downward body image comparisons were uniquely related to higher and lower, respectively, muscularity-oriented disordered eating. In women, higher upward body image comparisons were only uniquely related to higher muscularity-oriented disordered eating while higher downward body image comparisons were uniquely related to both outcomes. Higher body shame was uniquely related to higher thinness-oriented disordered eating across both groups and in men alone, higher body shame was also uniquely related to higher muscularity-oriented disordered eating. DISCUSSION: Findings, which tested the integration of tripartite influence, objectification, and social comparison theories, inform the prevention and treatment of disordered eating in Chinese older populations. PUBLIC SIGNIFICANCE: The present study is the first to describe theories of disordered eating (tripartite influence, objectification, and social comparison) in Chinese older adults. Findings suggested good model fit and the integrated models described meaningful variance in thinness- and muscularity-oriented disordered eating in Chinese older women and men. Findings extend existing theories of disordered eating and, pending further study, may inform theory-driven prevention and treatment approaches in Chinese older adults.

Mindfulness facets differentially relate to self-reported negative and positive emotional eating types in treatment-seeking adults with overweight/obesity.

BACKGROUND: Mindfulness is a meaningful therapeutic target in the treatment of emotional eating in adults with overweight/obesity. Descriptive research mapping relations between mindfulness facets and emotional eating types in treatment-seeking adults with overweight/obesity is needed. METHODS: Cross-sectional relations between mindfulness facets (i.e., acting with awareness, describe, non-judgment, non-reactive, and observe; Five Facet Mindfulness Questionnaire-Short Form) and emotional eating types (i.e., self-reported negative and positive emotional eating; Emotional Eating Scale-Revised, Emotional Appetite Questionnaire) were examined in a treatment-seeking sample of adults with overweight/obesity (N = 63). RESULTS: Significant bivariate correlations revealed negative relations between mindfulness facets and emotional eating types. Multiple regressions revealed that higher describe (ß = - 0.42, p = 0.004) mindfulness was associated with lower self-reported emotional eating-anger/anxiety; higher non-reactive (ß = - 0.31, p = 0.01) and non-judgment (ß = - 0.28, p = 0.02) mindfulness were associated with lower self-reported emotional eating-depression; and higher non-judgment (ß = 0.26, p = 0.04) mindfulness was associated with higher self-reported emotional eating-positive. CONCLUSIONS: Describe, non-judgment, and non-reactive mindfulness were uniquely and significantly associated with eating in response to negative and positive emotions. Results suggest the potential need for intervention programs to be sensitive to the multidimensional nature of mindfulness in the treatment of distinct types of emotional eating in adults with overweight/obesity. LEVEL OF EVIDENCE: V, cross-sectional descriptive study.

The Chinese version of the Functionality Appreciation Scale: Psychometric properties and measurement invariance across gender and age.

BACKGROUND: Functionality appreciation, as an important aspect of positive image, is associated with fewer body image disturbances, fewer disordered eating behaviors, and improved psychological well-being. However, it has been under-researched in Asian countries. The current work aimed to examine the psychometric properties of the Functionality Appreciation Scale (FAS) among four Chinese samples of different ages, and further examine measurement invariance and differences of the FAS across gender and age groups. METHODS: Exploratory and confirmatory factor analyses (EFA and CFA) were conducted to examine the factorial structure of the FAS among four Chinese samples of different ages, including middle school adolescents (n = 894, Mage = 12.17 years), high school adolescents (n = 1347, Mage = 15.07 years), young adults (n = 473, Mage = 21.95 years), and older adults (n = 313, Mage = 67.90 years). The measurement invariance of the FAS across gender and age was examined. Internal consistency reliability and construct validity were evaluated. RESULTS: The FAS had a unidimensional structure and was invariant across gender and age groups. The FAS presented sound psychometric properties in all age groups by gender, with good internal consistency reliability [e.g., high Cronbach's α values (.91 ~ .97)] and good construct validity (e.g., significant associations with body appreciation, body dissatisfaction, and disordered eating). Moreover, group comparisons showed minimal gender differences in functionality appreciation. However, significant age differences were found in functionality appreciation, with older ages generally associated with higher functionality appreciation. CONCLUSION: Overall, findings suggest that the FAS is a sound instrument to be used in the Chinese context. Furthermore, functionality appreciation was found to be higher in older adults than adolescents or young adults, suggesting the potential important role of aging in functionality appreciation.

Functionality appreciation, as a positive body image component emphasizing the appreciation on one's body for what it can do, is associated with fewer body image disturbances, fewer disordered eating behaviors, and improved psychological well-being. The Functionality Appreciation Scale (FAS) measures functionality appreciation and has been widely validated in a number of different populations. However, the psychometric properties of the FAS have not been systematically examined in the Chinese context, especially for adolescents and older adults. Results indicated that the psychometric properties of the FAS were sound and could be equally used to assess functionality appreciation in Chinese adolescents, young adults, and older adults.

Picky eating is associated with lower life satisfaction and elevated psychological distress and psychosocial impairment in Chinese pregnant women.

OBJECTIVE: This study assessed picky eating in pregnant women by exploring whether picky eating is associated with pregnant women's well-being, including life satisfaction, psychological distress, and psychosocial impairment. METHOD: Data collected were from 345 Chinese pregnant women ( M age = 29.95 years, SD = 5.58). Pearson correlation analyses were conducted to examine zero-order correlations between picky eating and well-being variables (i.e., life satisfaction, psychological distress, and psychosocial impairment). Hierarchical multiple regressions were conducted to examine the unique associations of picky eating with well-being variables, adjusting for demographic and pregnancy-related characteristics and thinness-oriented disordered eating. RESULTS: Picky eating was significantly and negatively correlated with life satisfaction (r = -.24, p < .001) and positively correlated with psychological distress (r = .37, p < .001) and psychosocial impairment (r = .50, p < .001). When adjusting for covariates and thinness-oriented disordered eating, picky eating was still significantly associated with lower life satisfaction, higher psychological distress, and higher psychosocial impairment. DISCUSSION: The findings suggest that picky eating may be a significant correlate of pregnant women's poorer well-being. Future research with longitudinal designs is warranted to further examine the temporal associations between picky eating and pregnant women's well-being. PUBLIC SIGNIFICANCE: Picky eating behaviors are poorly understood in pregnant women. Our results revealed that higher picky eating behaviors were associated with lower life satisfaction and higher psychological distress and psychosocial impairment in Chinese pregnant women. Researchers and clinicians may consider picky eating in the assessment and treatment of mental health and disordered eating in pregnant women.

Exploring the longitudinal association between body dissatisfaction and body appreciation in Chinese adolescents: A four-wave, random intercept cross-lagged panel model.

Although ample research evidence exists regarding the negative association between body dissatisfaction and body appreciation, the longitudinal association between these two constructs remains unclear, especially for adolescents. Thus, this study investigated the longitudinal association between body dissatisfaction and body appreciation and potential gender differences in this relationship in Chinese adolescents using four-wave longitudinal data. A sample of 2566 adolescents (54.10% girls) were included. A Random Intercept Cross-Lagged Panel Model (RI-CLPM) was conducted separately for boys and girls after controlling for baseline age and BMI z-scores. Results at the within-person level showed that for boys, body dissatisfaction at each wave negatively predicted body appreciation at the following wave, and body appreciation at Wave 2 and Wave 3 negatively predicted body dissatisfaction at Wave 3 and Wave 4. For girls, at the within-person level, body dissatisfaction at Wave 1 and Wave 2 negatively predicted body appreciation at Wave 2 and Wave 3, and body appreciation at Wave 3 negatively predicted body dissatisfaction at Wave 4. However, no gender differences in the RI-CLPM were found. The current findings enrich positive and negative body image research by providing evidence for the reciprocal relationships between body dissatisfaction and body appreciation in Chinese adolescents.

Testing the associations between internalized cisgenderism, self-objectification, body shame, and mental health correlates in the framework of the pantheoretical model of dehumanization: A study in Chinese transgender adults.

As an integrated framework informed by the Minority Stress Model and Objectification Theory, the Pantheoretical Model of Dehumanization was proposed to better understand mental health outcomes in transgender individuals. With a sample of 200 Chinese transgender adults, the present study tested the associations and potential mechanisms between internalized cisgenderism, self-objectification, body shame, and mental health correlates in the framework of the Pantheoretical Model of Dehumanization. Correlation and regression analyses were used. Results showed that internalized cisgenderism was positively related to body shame, psychological distress, disordered eating, non-suicidal self-injury (NSSI), suicidal ideation, and suicide attempts. Body shame showed significant indirect effects in the association between internalized cisgenderism and suicide attempts, and in the associations between internalized cisgenderism and psychological distress, disordered eating, and NSSI. In addition, body shame had significant indirect effects in the associations between body surveillance and disordered eating, NSSI, and suicide attempts, and in the association between body surveillance and psychological distress. As the first study testing the associations of core variables in the Pantheoretical Model of Dehumanization in a Chinese transgender sample, the findings largely supported the model in describing meaningful variance in Chinese transgender adults' psychological distress, disordered eating, and self-injurious thoughts and behaviors.

Muscularity teasing and its relations with muscularity bias internalization, muscularity-oriented body dissatisfaction, and muscularity-oriented disordered eating in Chinese adult men.

Despite increasing research on weight teasing and other forms of appearance teasing, muscularity teasing, which occurs when an individual is victimized due to low muscularity, has not yet received research attention. Given the solid evidence of positive relations between weight teasing and thinness-oriented body dissatisfaction and disordered eating, we aimed to tap into muscularity teasing and examine its relations with muscularity-oriented body dissatisfaction and muscularity-oriented disordered eating (e.g., rigid dietary rules for enhancing muscularity). A sample of 500 Chinese men, aged 18 - 62 years, were recruited online, and they competed questionnaires assessing muscularity teasing, muscularity bias internalization, muscularity-oriented body dissatisfaction, and muscularity-oriented disordered eating. Correlation analyses showed that muscularity teasing was significantly related to muscularity bias internalization (r = 0.55, p < .001), muscularity-oriented body dissatisfaction (r = 0.50, p < .001), and muscularity-oriented disordered eating (r = 0.38, p < .001). Structural equation modelling indicated that muscularity bias internalization and muscularity-oriented body dissatisfaction, as concurrent mediators, fully mediated the relationships between muscularity teasing and muscularity-oriented disordered eating. Findings extend existing knowledge in appearance teasing research to encompass muscularity teasing in order to better understand the etiology of muscularity-oriented body dissatisfaction and muscularity-oriented disordered eating.
