Adaptation and implementation of body project as a universal body image program in Mexico and Latin America.

The Body Project (BP) intervention for body image issues is supported by extensive efficacy and effectiveness research, most of which has been conducted in the United States. The BP uses cognitive dissonance to help participants critique the ideal appearance through written, verbal, and behavioral exercises. This reduces the internalization of the appearance ideal, which in turn decreases body dissatisfaction symptoms and, in some individuals, the onset of eating disorders. To broadly implement this program in Mexico and Latin America, Comenzar de Nuevo (CdN), a non-profit organization for eating disorder treatment, partnered with the Body Project Collaborative in 2014. Together, they created a training and implementation infrastructure. This paper explores the adaptation of BP and its implementation in Mexico and Latin America. We used sustainable business, marketing, and educational models to fulfill CdN's mission to reduce eating disorder risk factors, including weight stigma, in the Latin American region. By integrating strategies to combat weight stigma within our program delivery, we strive to contribute to a more inclusive and supportive environment. We trained master trainers, regular trainers, and/or group facilitators from Argentina, Bolivia, Colombia, Costa Rica, Chile, Dominican Republic, El Salvador, Guatemala, Mexico, Panama, and Spain; and implemented the BP in 15 public schools supported by sponsorship programs. This paper provides crucial lessons learned, future directions, and implications for dissemination and implementation efforts in this region of the world.

Investigating the factor structure and measurement invariance of the eating disorder examination questionnaire (EDE-Q) among cisgender gay men and lesbian women from the United States.

BACKGROUND: Although the Eating Disorder Examination-Questionnaire (EDE-Q) is one of the most widely used self-report assessments of eating disorder symptoms, evidence indicates potential limitations with its original factor structure and associated psychometric properties in a variety of populations, including sexual minority populations. The aims of the current investigation were to explore several previously published EDE-Q factor structures and to examine internal consistency and measurement invariance of the best-fitting EDE-Q model in a large community sample of cisgender gay men and cisgender lesbian women. METHODS: Data were drawn from 1624 adults (1060 cisgender gay men, 564 cisgender lesbian women) who participated in The PRIDE Study, a large-scale longitudinal cohort study of sexual and gender minorities from the United States. A series of confirmatory factor analyses (CFAs) were conducted to explore the fit of eight proposed EDE-Q models; internal consistency (Cronbach's alphas, Omega coefficients) and measurement invariance (multi-group CFA) were subsequently evaluated. RESULTS: A brief seven-item, three-factor (dietary restraint, shape/weight overvaluation, body dissatisfaction) model of the EDE-Q from Grilo et al. (Obes Surg. 23:657-662, 2013), consistently evidenced the best fit across cisgender gay men and lesbian women. The internal consistencies of the three subscales were adequate in both groups, and measurement invariance across the groups was supported. CONCLUSIONS: Taken together, these findings support the use of the seven-item, three-factor version of the EDE-Q for assessing eating disorder symptomatology in cisgender gay men and lesbian women. Future studies can confirm the current findings in focused examinations of the seven-item, three-factor EDE-Q in diverse sexual minority samples across race, ethnicity, socioeconomic status, and age ranges.

We asked cisgender gay men and lesbian women in The PRIDE Study to fill out a widely used survey about eating disorders, the Eating Disorder Examination-Questionnaire. We found that a version of this questionnaire based on seven questions including three parts­(1) dietary restraint, (2) shape and weight overvaluation, and (3) body dissatisfaction­had the best fit. These findings can assist doctors and scientists in understanding eating disorders in cisgender gay men and lesbian women.

Investigating the factor structure and measurement invariance of the Eating Disorder Examination-Questionnaire (EDE-Q) in a community sample of gender minority adults from the United States.

OBJECTIVE: The Eating Disorder Examination-Questionnaire (EDE-Q) is one of the most widely used self-report assessments of eating disorder symptoms. However, evidence indicates potential problems with its original factor structure and associated psychometric properties in a variety of populations, including gender minority populations. The aim of the current investigation was to explore several previously published EDE-Q factor structures and to examine internal consistency and measurement invariance of the best-fitting EDE-Q model in a large community sample of gender minority adults. METHODS: Data were drawn from 1567 adults (337 transgender men, 180 transgender women, and 1050 gender-expansive individuals) who participated in The PRIDE Study, a large-scale longitudinal cohort study of sexual and gender minorities from the United States. A series of confirmatory factor analyses (CFAs) were conducted to explore the fit of eight proposed EDE-Q models; internal consistency (Cronbach's alphas, Omega coefficients) and measurement invariance (multi-group CFA) were subsequently evaluated. RESULTS: A brief seven-item, three-factor (dietary restraint, shape/weight overvaluation, body dissatisfaction) model of the EDE-Q consistently evidenced the best fit across gender minority groups (transgender men, transgender women, gender-expansive individuals). The internal consistencies of the three subscales were adequate in all groups, and measurement invariance across the groups was supported. DISCUSSION: Taken together, these findings support the use of the seven-item, three-factor version of the EDE-Q for assessing eating disorder symptomatology in gender minority populations. Future studies can confirm the current findings in focused examinations of the seven-item, three-factor EDE-Q in diverse gender minority samples across race, ethnicity, socioeconomic status, and age ranges. PUBLIC SIGNIFICANCE STATEMENT: Although transgender individuals have greater risk of developing an eating disorder, the factor structure of the Eating Disorder Examination-Questionnaire, one of the most widely used eating disorder assessment measures, has not been explored in transgender adults. We found that a seven-item model including three factors of dietary restraint, shape and weight overvaluation, and body dissatisfaction had the best fit among transgender and nonbinary adults.

Validation of the muscularity-oriented eating test in adult women in China.

OBJECTIVE: Research on muscularity-oriented disordered eating has grown in recent years. However, the bulk of this research has focused on men and Western populations. Limited research is available in non-Western populations of women (e.g., China) which is likely due to the lack of valid instruments in these populations. Thus, the current study aimed to describe the validity and reliability of the Muscularity-Oriented Eating Test (MOET) in Chinese women. METHOD: Two online surveys (survey one: n = 599, Mage = 29.49, SD = 7.36; survey two: n = 201, Mage = 28.42, SD = 7.76) were conducted to explore the psychometric properties of the MOET in Chinese women. In survey one, the factor structure of the MOET was examined via exploratory and confirmatory factor analyses (EFA and CFA). Internal consistency reliability and convergent and incremental validity of the MOET were also assessed. In survey two, test-retest reliability across a 2-week interval was examined. RESULTS: EFA and CFA provided support for the unidimensional factor structure of the MOET in Chinese adult women. The MOET presented good internal consistency and test-retest reliability and convergent validity via large, positive associations with theoretically related constructs (e.g., thinness-oriented disordered eating, drive for muscularity, and psychosocial impairment). Finally, muscularity-oriented disordered eating described unique variance in psychosocial impairment, providing support for the incremental validity of the MOET. DISCUSSION: The sound psychometric structure of the MOET was supported in Chinese women. Continued research is needed to describe muscularity-oriented disordered eating in Chinese women to contribute to this significant gap in the literature. PUBLIC SIGNIFICANCE: The Muscularity-Oriented Eating Test (MOET) is a measure specifically developed for assessing muscularity-oriented disordered eating. This study examined the validity and reliability of the MOET in Chinese women. The results showed that the MOET had sound validity and reliability in Chinese women. Thus, the MOET is a valuable tool for advancing the understanding of the muscularity-oriented disordered eating of women from the Chinese context.

Eating disorder risk among college sorority and fraternity members within the United States.

Eating disorder (ED) risk is elevated among college populations in the United States. However, current research assessing the relative risk of ED symptomatology within Greek life has been mixed. We aimed to assess whether Greek Life Affiliation (GA) was associated with a greater risk for ED among college students in the United States as measured on the SCOFF questionnaire. Data were extracted from the Healthy Minds Study, which surveyed 44,785 American college students across 79 schools. The survey asked about GA, Greek life housing, and included the SCOFF questionnaire. This study utilized multiple logistic regressions and chi-square analyses (n = 44785) to analyze the data. GA failed to predict ED-risk in both women (aOR = 0.98 [95% CI = 0.90, 1.06]) and men (aOR = 1.07 [95% CI = 0.92, 1.24]). Similarly, among female [aOR = 1.00 [95% CI = 0.46, 2.12]) and male participants (aOR = 1.06 [95% CI = 0.59, 1.98]), sorority/fraternity housing also failed to predict ED-risk. Greek Life Affiliation is not associated with greater ED-risk among US college students.

Validation and measurement invariance of the Muscularity-Oriented Eating Test among Brazilian men and women.

OBJECTIVE: The Muscularity-Oriented Eating Test (MOET) is a 15-item unidimensional scale, designed to assess eating practices that occur in the pursuit of a muscular body. The aim of the present study was to describe the translation and cultural adaptation of the MOET to Brazilian Portuguese, to explore its factor structure and measurement invariance, and to evaluate its internal consistency, three-week test-retest reliability, and convergent validity in a community sample of Brazilian men and women. METHOD: After the back-translation procedure, the Brazilian MOET was administered online to a sample of 1246 adults (634 men and 612 women), along with measures of drive for muscularity, muscle dysmorphia symptoms, muscular/athletic-ideal internalization, disordered eating behaviors, and exercise dependence. RESULTS: Findings from an exploratory factor analysis and a confirmatory factor analysis revealed a one-factor structure and adequate internal consistency for men (ω = 0.86; α = 0.86) and women (ω = .84; α = .83). Measurement invariance across gender was supported. In addition, the scale demonstrated good three week test-retest reliability for both men (ICC = .96; p < .001) and women (ICC = .92; p < .001), and the subscales revealed moderate to large associations with drive for muscularity, muscle dysmorphia symptoms, muscular/athletic-ideal internalization, disordered eating, and exercise dependence. CONCLUSION: This study supports the validity and reliability of the MOET in a community sample of Brazilian men and women and represents an advance in measures of muscularity-oriented disordered eating in Brazilian adults, allowing for future cross-cultural studies in this field. PUBLIC SIGNIFICANCE: The Muscularity-Oriented Eating Test (MOET) is a measure of muscularity-oriented disordered eating, which assess strict adherence to diet rules, including the food's macronutrient content, regulation of protein intake, and eating less or more to influence muscle gain. This study evaluated the validity and reliability of the MOET in a community sample of Brazilian men and women. Our findings represent an advance in measures of muscularity-oriented disordered eating in Brazilian adults.

Factor structure and psychometric properties of a multicultural Spanish-language version of the Eating Disorder-15 in a nonclinical sample of Chilean women.

OBJECTIVE: The Eating Disorder-15 (ED-15) is a brief measure developed for the routine assessment of eating disorder (EDs), despite its use in research settings having increased over the last few years. To assess the psychometric properties of the ED-15 in a nonclinical sample of Chilean women. METHOD: A multicultural Spanish-language version was developed through combined translation techniques. University female students (N = 380) (Mage 22.32, SD = 2.48) were recruited through social media. After providing their informed consent, participants completed a battery of questionnaires online. RESULTS: A bi-factor model replicating the bi-factor structure and providing support for the general factor showed the best fit to the data. Moderate-to-strong correlations with measures of EDs, physical comparison, body appreciation, social physique anxiety, and depressive symptoms are presented as evidence of concurrent and convergent validity. Items analyses revealed strong correlations between manifest variables, their correspondent latent variable and the general factor (rs  = .60 to .89, ps < .001). Additionally, current findings provide support for the internal consistency of the scale (Cronbach's alpha and Omega values were ≥ .80) and test-retest reliability (ICCs = .84 to .89, ps < .001). DISCUSSION: Like previous findings, the current study provides validity to the original bi-factor structure of the ED-15 and additional validity to a general factor. The availability of this multicultural Spanish-language version would provide session-by-session assessment, providing crucial information throughout treatment. Also, the availability of the current measure would contribute to further research efforts in a yet understudied population such as Hispanic women. PUBLIC SIGNIFICANCE: The Eating Disorder-15 (ED-15) is a promising measure meant to assess session-by-session change for clinical and research purposes. The availability of a Multicultural Spanish language version of the ED-15 allows for routine clinical assessment and represents a contribution for research efforts in a yet understudied populations such as Hispanic women.

OBJETIVO: El Eating Disorder-15 (ED-15) es una breve medida de trastornos alimentarios (TCA) diseñada para realizar una evaluación rutinaria, a pesar de que su uso en la investigación ha crecido en los últimos años. Evaluar las propiedades psicométricas del ED-15 en una muestra no clínica de mujeres chilenas. MÉTODO: Se desarrolló una versión multicultural al español mediante técnicas de traducción combinadas. Las estudiantes universitarias (N = 380) (Medad 22.32, DT = 2.48) fueron reclutadas en redes sociales. Después de dar su consentimiento, las participantes completaron cuestionarios en línea. RESULTADOS: un modelo bifactorial que replica la estructura de dos factores y proporciona soporte para un factor general mostró el mejor ajuste. Correlaciones moderadas a fuertes con medidas de TCA, comparación física, apreciación corporal, ansiedad social física y síntomas depresivos se presentan como evidencia de validez concurrente y convergente. Análisis de ítems revelaron fuertes correlaciones entre las variables manifiestas, su correspondiente variable latente y el factor general (rs  = .60 a .89, ps < .001). Los hallazgos actuales respaldan la consistencia interna (alfa Cronbach y Omega > .80) y la confiabilidad test-retest (ICC = .84 a .89, ps < .001). DISCUSIÓN: El estudio actual proporciona validez a la estructura original de 2 factores del ED-15 y validez adicional a un factor general. La disponibilidad de esta versión multicultural en español permitirá una evaluación sesión por sesión, brindando información clínica crucial al tratamiento. Su disponibilidad permitirá el desarrollo de investigaciones en una población aún poco estudiada como la de mujeres latinas.

Psychometric evaluation of the muscle dysmorphic disorder inventory (MDDI) among gender-expansive people.

PURPOSE: Muscle dysmorphia is generally classified as a specific form of body dysmorphic disorder characterized by a pathological drive for muscularity and the preoccupation that one is too small or not sufficiently muscular. The majority of research on the condition has been conducted in cisgender men with a paucity of literature on gender minority people, a population that is at risk for muscle dysmorphia. One of the most widely used measures of muscle dysmorphia symptoms, the Muscle Dysmorphic Disorder Inventory (MDDI), has not been psychometrically validated for use in gender minority samples, the aim of the present study. METHODS: We evaluated the psychometric properties of the MDDI in a sample of 1031 gender-expansive individuals (gender minority people whose gender identity differs from that assumed for their sex assigned at birth and is not exclusively binary man or woman) aged 18-74 who were part of The PRIDE Study, a large-scale, U.S., longitudinal cohort study. RESULTS: Using a two-step, split-sample exploratory and confirmatory factor analytic approach, we found support for the original three-factor structure of the measure. The subscales showed adequate internal consistency, and convergent validity was supported based on significant associations of the MDDI subscale scores with theoretically related scores on a widely used measure of disordered eating. CONCLUSIONS: These findings provided novel support for adequate psychometric properties of the MDDI in a sample of gender-expansive individuals, facilitating the use of this measure in future research on muscle dysmorphia in this understudied and at-risk population.

Gender-expansive describes gender identities that do not fit within the binary gender identity system, such as man or woman. We asked gender-expansive participants in The PRIDE Study to fill out a widely used survey about muscle dysmorphia (when someone is worried about not being muscular enough). We found that this issue about muscularity has three parts for gender-expansive people: (1) a desire to be bigger and more muscular, (2) dissatisfaction with the way their body looks, and (3) problems with normal life functions. We find that this survey is appropriate for use in gender-expansive people. These results can help providers and researchers understand the muscle-related problems that gender-expansive people face.

Psychometric validation of the Muscle Dysmorphic Disorder Inventory (MDDI) among U.S. transgender men.

Muscle dysmorphia (MD) is characterized by a pervasive belief or fear of insufficient muscularity and an elevated drive for muscularity, representing the pathological and extreme pursuit of muscularity. Psychometric properties of one of the most widely used measures of MD symptoms-the Muscle Dysmorphic Disorder Inventory (MDDI)-have yet to be evaluated in transgender men despite emerging evidence suggesting differential risk for MD symptoms in this population. In this study, we assessed the psychometric properties of the MDDI in a sample of 330 transgender men ages 18-67 years who participated in a large-scale national longitudinal cohort study of sexual and gender minority adults in the U.S. Using a two-step, split-sample approach, an initial exploratory factor analysis supported a three-factor structure and a subsequent confirmatory factor analysis of a re-specified three-factor model demonstrated good overall fit (χ2/df = 1.84, CFI =0.94, TLI =0.92, RMSEA =0.07 [90% CI =0.05,.09], SRMR =0.08). Moreover, results supported the internal consistency and convergent validity of the MDDI subscales in transgender men. Findings inform the use of the MDDI among transgender men and provide a foundation to support further work on the MDDI and MD symptoms among gender minority populations.

Demographic and sociocultural predictors of sexuality-related body image and sexual frequency: The U.S. Body Project I.

Body image is a critical component of an individual's sexual experiences. This makes it critical to identify demographic and sociocultural correlates of sexuality-related body image: the subjective feelings, cognitions, and evaluations related to one's body in the context of sexual experience. We examined how sexuality-related body image differed by gender, sexual orientation, race, age, and BMI. Four items assessing sexuality-related body image were completed by 11,620 U.S. adults: self-perceived sex appeal of their body, nude appearance satisfaction, and the extent to which they believed that body image positively or negatively affected their sexual enjoyment and feelings of sexual acceptability as a partner. Men reported slightly less nude appearance dissatisfaction and fewer negative effects of body image on sexual enjoyment and sexual acceptability than women, but did not differ in reported sex appeal. Poorer sexuality-related body image was reported by people with higher BMIs, not in relationships, who had sex less frequently, among White compared to Black women and men, and among gay compared to heterosexual men. Data also revealed a subgroup of respondents who reported that their body image had a positive impact on their sex lives. The findings highlight a need for interventions addressing sexuality-related body image.

Pathways from sociocultural and objectification constructs to body satisfaction among men: The U.S. Body Project I.

According to the tripartite influence model, body dissatisfaction is shaped by internalizing cultural appearance ideals stemming from appearance-related family, peer, and media pressures. This model was developed for women, but emerging evidence points to its relevance for men's body image. This study advanced this budding research by (a) integrating muscular-ideal internalization alongside lean-ideal internalization and body surveillance into the model, (b) examining two positive dimensions of body image as outcomes (body image quality of life and appearance evaluation), and (c) testing this model in national online sample of 5293 men. Structural equation modeling supported the model. Family, peer, and media pressures related to higher lean-ideal internalization, which related to higher body surveillance and poorer body image outcomes. Peer and media pressures related to higher muscular-ideal internalization, which related to higher body surveillance but more adaptive body image outcomes. We further examined whether model variables and paths differed based on men's body mass index (BMI). Men with higher BMIs evidenced a stronger path between body surveillance and body image outcomes. These findings highlight the usefulness of sociocultural models for understanding men's body image experiences.

Sexual orientation differences in pathways from sociocultural and objectification constructs to body satisfaction: The U.S. Body Project I.

Objectification theory and the tripartite influence model provide useful frameworks for understanding the body image experiences of men and women. However, there is little systematic investigation of how sexual orientation moderates the links between these constructs and body image satisfaction. It has been hypothesized, for example, that the associations of surveillance (i.e., monitoring of one's appearance due to objectification by others) would be strongest for groups targeted by the male gaze (e.g., gay men, lesbian women, and bisexual men and women). Here we proposed an integrated sociocultural model and examined these pathways in multigroup structural equation models in a national sample of heterosexual, bisexual, and lesbian women (ns = 5395; 598; 213, respectively), and heterosexual, bisexual, and gay men (4869; 194; and 194, respectively) aged 18-65 years. Sexual orientation moderated some of these pathways. The most consistent pattern was that appearance pressures were internalized to a greater extent among bisexual participants. The pathways to poorer body image were generally similar among heterosexual and gay/lesbian men and women. These findings highlight the importance of examining sexual orientation-specific influences on body image across diverse groups, as well as the commonalities in the experiences of men and women across sexual orientations.

Validation of the Muscle Dysmorphic Disorder Inventory (MDDI) in Brazilian Women.

Despite high levels of body dissatisfaction and an increasing drive for muscularity among Brazilian women, most of the existing literature on muscle dysmorphia focuses on men and has mainly been conducted in Western and English-speaking regions. As a result, one of the most widely used assessment tools for symptoms of the disorder, the Muscle Dysmorphic Disorder Inventory (MDDI), has not yet been evaluated in Brazilian women-an at-risk population. In the present study, we perform a psychometric evaluation of the Brazilian Portuguese translation of the MDDI in a sample of 515 women. We evaluated the factor structure using a two-step, split-sample exploratory and confirmatory factor analytic approach, which supported the original three-factor structure of the measure. Additionally, we found good internal consistency, convergent validity, and test-retest reliability of the measure. Collectively, these results support the use of the measure in Brazilian women and provide a foundation to expand the literature in this population.

Racial identity differences in pathways from sociocultural and objectification constructs to body satisfaction: The U.S. Body Project I.

Racial minority men and women face a wide variety of appearance-related pressures, including ones connected to their cultural backgrounds and phenotypic features associated with their identity. These body image concerns exist within a larger context, wherein racial minorities face pressures from multiple cultures or subcultures simultaneously to achieve unrealistic appearance ideals. However, limited research has investigated racial differences in the relationships between theorized sociocultural risk factors and body image in large samples. This study tests pathways from an integrated sociocultural model drawing on objectification theory and the tripartite influence model to three key body image outcomes: appearance evaluation, body image quality of life, and face image satisfaction. These pathways were tested using multigroup structural equation modeling in a national sample of White, Black, Hispanic, and Asian men and women (ns = 205-4797 per group). Although many hypothesized associations were similar in strength across groups, race moderated some of the pathways between sociocultural pressures (media, peer, family), internalization of appearance ideals (thin-ideal, muscular/athletic), appearance surveillance, and body image outcomes. Findings support the likely role of both shared and specific risk factors for body image outcomes, suggesting avenues for tailoring adapted interventions in order to target culturally-salient risk factors.

Appearance and performance-enhancing drugs and supplements, eating disorders, and muscle dysmorphia among gender minority people.

OBJECTIVE: Appearance and performance-enhancing drugs and supplements (APEDS) can be used to enhance muscle growth, athletic performance, and physical appearance. The aim of this study was to examine the lifetime use of APEDS and associations with eating disorder and muscle dysmorphia symptoms among gender minority people. METHOD: Participants were 1653 gender minority individuals (1120 gender-expansive [defined as a broad range of gender identities that are generally situated outside of the woman-man gender binary, e.g., genderqueer, nonbinary] people, 352 transgender men, and 181 transgender women) recruited from The Population Research in Identity and Disparities for Equality Study in 2018. Regression analyses stratified by gender identity examined associations of any APEDS use with eating disorder and muscle dysmorphia symptom scores. RESULTS: Lifetime APEDS use was common across groups (30.7% of gender-expansive people, 45.2% of transgender men, and 14.9% of transgender women). Protein supplements and creatine supplements were the most commonly used APEDS. Among gender-expansive people and transgender men, lifetime use of any APEDS was significantly associated with higher eating disorder scores, dietary restraint, binge eating, compelled/driven exercise, and muscle dysmorphia symptoms. Any APEDS use was additionally associated with laxative use among gender-expansive people. Among transgender women, use of any APEDS was not significantly associated with eating disorder or muscle dysmorphia symptoms. DISCUSSION: APEDS use is common and associated with eating disorder and muscle dysmorphia symptoms in gender-expansive people and transgender men, thus highlighting the importance of assessing for these behaviors and symptoms among these populations, particularly in clinical settings. PUBLIC SIGNIFICANCE: This study aimed to examine APEDS use among gender minority people. We found that 30.7% of gender-expansive (e.g., nonbinary) people, 45.2% of transgender men, and 14.9% of transgender women reported lifetime APEDS use, which was associated with eating disorder and muscle dysmorphia symptoms in transgender men and gender-expansive people. Clinicians should assess for these behaviors in gender minority populations.

Pathways from sociocultural and objectification constructs to body satisfaction among women: The U.S. Body Project I.

Objectification theory proposes that widespread sexualization causes women to engage in surveillance of their appearance. We integrated this concept into a model with constructs from the tripartite influence model, which proposes that body dissatisfaction is a result of internalizing cultural notions of thin ideal beauty that stem from family, peer, and media appearance-related pressures. We tested this model with an online sample of 6327 adult women. Specifically, we tested whether these pressures predicted increased thin-ideal and muscular-ideal internalization, leading to greater body surveillance, and in turn lower appearance evaluation and body image quality of life. Structural equation modeling supported many aspects of the model. Family, peer, and media pressures related to higher thin-ideal internalization, which related to higher body surveillance and lower appearance evaluation. Peer and media pressures related to higher muscular-ideal internalization, which related to lower appearance evaluation. However, muscular-ideal internalization was not related to body image quality of life. An indirect relationship emerged between thin-ideal internalization and body image outcomes via body surveillance. Body mass index (BMI) moderated several of these model paths. Findings highlight the value of this integrated sociocultural model, and of BMI as an important moderating factor when examining objectification and tripartite influence models.

Psychometric Properties of the Eating Disorder Inventory-3 (EDI-3) in Chilean Youth.

The aim of this study was to analyze the psychometric properties of the Eating Disorder Inventory (EDI)-3 test to evaluate eating disorders in young Chilean population. Methods: The sample consisted of 1,091 Chilean adolescents and young people (i.e., 476 men and 615 women) between 15 and 28 years old, from the metropolitan region, and four regions from the coast and south-central zone of the country. The reliability and factorial structure of the instrument were analyzed, replicating the confirmatory factor analyses of Brookings et al. (2020), evaluating four additional models that included bifactor exploratory structural equation modeling (ESEM), bifactor, and two-bifactor. Results: A majority of the subscales presented alphas and omegas equal to or greater than 0.70, with the exception of asceticism (α = 0.543, ω = 0.552) and interpersonal alienation (α = 0.684, ω = 0.695) scales, which are consistent with the values of the Spanish and Mexican non-clinical samples. The best fit indices were obtained by the ESEM two-bifactor model, with twelve specific factors corresponding to the EDI-3 subscales and two general orthogonal factors (i.e., risk subscales and psychological subscales), consistently with the theoretical basis.

Demographic predictors of body image satisfaction: The U.S. Body Project I.

We examined how gender, body mass, race, age, and sexual orientation were linked to appearance evaluation, overweight preoccupation, and body image-related quality of life among 11,620 adults recruited via Mechanical Turk. Men were less likely than women to report low appearance evaluation, high overweight preoccupation, negative effects of body image on their quality of life, being on a weight-loss diet, and trying to lose weight with crash diets/fasting. Racial differences were generally small, but greater appearance evaluation was reported by Black men versus other groups and Black women versus White women. Across all measures, gay and bisexual men reported poorer body image than heterosexual men, with only small effect sizes observed for sexual orientation differences among women. Body mass, but not age, was strongly associated with body image. The prevalence of poor body image highlights the need for interventions. On the positive side, half of men and women reported high appearance evaluation. Examination of this group could identify factors promoting positive body image.
