RESUMO

OBJECTIVE: Gay and bisexual men are at an increased risk for eating disorders (EDs) and muscle dysmorphia (MD) compared with their heterosexual counterparts. Existing dissonance-based (DB) EDs prevention programs for this population have been evaluated in the United States; however, these programs have not been evaluated in the Brazilian context. Thus, we investigated the feasibility, acceptability, and efficacy of a DB ED prevention program (i.e., the PRIDE Body Project) among Brazilian cisgender gay and bisexual men. METHOD: Eligible men were randomly assigned to either a DB intervention (n = 74) condition or an assessment-only control (AOC) condition (n = 75). Participants completed measures assessing ED and MD risk and protective factors at baseline, post-intervention, 1-month, 6-month, and 1-year follow-up. Those in the intervention condition also completed acceptability measures. RESULTS: Feasibility and acceptability ratings were highly favorable. Regarding efficacy, post-intervention results were not significant, except for self-objectification, which showed a significantly greater decrease in the DB condition compared with the AOC condition at all time-points of follow-ups (Cohen's d = -0.31 to -0.76). At follow-up, the DB condition showed significantly greater decreases in appearance-ideal internalization, drive for muscularity, self-objectification, ED and MD symptoms at 1-month, 6-month, and 1-year follow-ups (d = -0.33 to -0.92) compared with the AOC condition. Significant increases were observed in the DB compared with the AOC condition for body appreciation at 1-month, 6-month, and 1-year follow-ups (d = 0.31-0.81). DISCUSSION: Results support the feasibility, acceptability, and efficacy of the PRIDE Body Project up to 1-year in Brazilian cisgender gay and bisexual men.

RESUMO

Among gender-expansive individuals and transgender men, body appreciation can play a protective role against minority stressors and is associated with gender euphoria. The Body Appreciation Scale (BAS-2; Tylka & Wood-Barcalow, 2015) is a leading measure of body appreciation that has been mainly validated in cisgender and mixed-gender samples; however, it has not been validated among Brazilian gender-expansive individuals and transgender men. Therefore, we evaluated the psychometric properties of the BAS-2 among adult Brazilian gender-expansive individuals and transgender men. Participants (158 gender-expansive individuals and 138 transgender men) were recruited through social media in Brazil. Confirmatory Factor Analysis (CFA) supported the original 10-item, unidimensional solution. Multigroup CFA showed configural, metric, and scalar invariance of the BAS-2 between gender-expansive individuals and transgender men. Moreover, the BAS-2 demonstrated significant negative associations, ranging from small to large, with self-objectification, drive for muscularity, and appearance-ideal internalization. We also found good internal consistency and test-retest reliability of the measure. Taken together, our results support the psychometric properties of the BAS-2 among Brazilian gender-expansive individuals and transgender men. The present work offers a valuable contribution towards better understanding facets of positive body image across gender-expansive and transgender populations.

RESUMO

Objective: To test the efficacy of a dissonance-based (DB) intervention in targeting risk factors for eating disorders (EDs) and predisposing factors for muscle dysmorphia (MD) symptoms in body-dissatisfied Brazilian men over 1 year of follow-up and evaluate whether reductions in body-ideal internalization would mediate the intervention's impact on ED and MD symptoms. Methods: Participants were randomized to a two-session DB intervention (n=89) or assessment-only control (AOC) (n=91), and completed validated measures assessing body-ideal internalization, body dissatisfaction, ED, and MD symptoms at baseline, post-intervention, 1-month, 6-month, and 1-year follow-ups. Results: The DB condition showed significantly greater reductions in MD symptoms and body dissatisfaction compared with the AOC group over a 1-year follow-up, while significant differences were not observed for body-ideal internalization and ED symptoms. Changes in body-ideal internalization from baseline to 1-month follow-up completely mediated the relationship between condition and the changes observed in both ED and MD symptoms. Conclusion: These results provide further evidence of the efficacy of the tested intervention through 1-year follow-up in reducing body dissatisfaction and MD symptoms, but no such result was observed for body-ideal internalization and EDs. Our findings provide support for theoretical models of eating pathology and MD symptoms in Brazilian men. Clinical Trial Registration: Brazilian Registry of Clinical Trials (ReBEC): RBR-27dc264.

RESUMO

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.

RESUMO

Despite high levels of muscularity concerns among sexual-minority men, most of the existing literature on the drive for muscularity and muscle dysmorphia focuses on heterosexual men and has mainly been conducted in Western and English-speaking regions. The present study aimed to evaluate the psychometric properties of the Drive for Muscularity Scale (DMS) and the Muscle Dysmorphic Disorder Inventory (MDDI) in Brazilian cisgender gay and bisexual adult men who were 18-50 years old. We evaluated the factor structure of both measures using a two-step, split-sample exploratory (EFA; n = 704) and confirmatory (CFA; n = 705) factor-analytic approach, which supported the original three-factor structure of the MDDI and resulted in a reduced two-factor solution with 13 items for the DMS. Convergent validity was supported through associations of the DMS and the MDDI with eating disorder symptoms, body-ideal internalization, self-objectification beliefs and behaviors, and body appreciation measures. Additionally, we found good internal consistency, and test-retest reliability of both measures. Results support the validity and reliability of the DMS and the MDDI in Brazilian cisgender gay and bisexual adult men and will support future studies exploring these constructs in Brazilian sexual-minority men.

RESUMO

OBJECTIVE: One of the most widely used assessment tools for disordered eating attitudes and behaviors, the Eating Disorder Examination Questionnaire (EDE-Q), has not yet been evaluated in Brazilian cisgender gay and bisexual men-an at-risk population given the extent of minority stressors in Brazilian culture. The present study aimed to assess the psychometric properties of the EDE-Q among Brazilian cisgender gay and bisexual adult men. METHOD: The Brazilian EDE-Q was administered to a sample of 1409 gay and bisexual adult men, along with measures of self-objectification, body-ideal internalization, drive for muscularity, muscle dysmorphia symptoms, and body appreciation. The factor structure of the Brazilian EDE-Q was assessed using a two-step, split-sample exploratory (EFA; n = 704) and confirmatory factor analytic approach (CFA; n = 705). Additionally, convergent validity, internal consistency, and 2-week test-retest reliability were assessed. RESULTS: Findings from an EFA and CFA revealed a one-factor structure with 22 items and adequate internal consistency (ω = .92, 95% CI = [.91, .93]). Moreover, the scale demonstrated good 2-week test-retest reliability (ICC = .86, 95% CI = [.82, .88], p < .001). The EDE-Q scores showed positive associations with self-objectification, body-ideal internalization, muscle dysmorphia symptoms, and drive for muscularity, as well as a negative association with body appreciation. DISCUSSION: Results provide support for the use of the EDE-Q using a one-factor structure in Brazilian cisgender gay and bisexual adult men and give insights for future studies on eating disorders in sexual minorities in Latin America. PUBLIC SIGNIFICANCE: The Eating Disorder Examination Questionnaire (EDE-Q) is one of the most widely used self-report measures of eating disorder symptoms. However, there is a lack of research on the validity and reliability of the EDE-Q in Latin American countries. This study evaluated the validity and reliability of the EDE-Q in Brazilian cisgender gay and bisexual adult men. Our findings give insights for future studies on eating disorders in sexual minorities in Latin America.

RESUMO

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.

RESUMO

Positive body image may be particularly relevant to assess for Brazilian gay and bisexual men, given the extent of sexual minority stressors (e.g., harassment, discrimination) in Brazilian culture, which can impair one's self-perception and concept. Thus, the purpose of the present study was to assess the psychometric properties of the Body Appreciation Scale-2 (BAS-2) among Brazilian cisgender gay and bisexual adult men, aged 18-50 years. We evaluated the factor structure using a two-step, split-sample exploratory (EFA; n = 682) and confirmatory factor analytic approach (CFA; n = 727), which supported the one-factor structure of the measure. Additionally, convergent validity, internal consistency, and 2-week test-retest reliability were assessed. The BAS-2 scores showed small to large negative correlations with self-objectification beliefs and behaviors, drive for muscularity and appearance-ideal internalization measures. We also found good internal consistency and test-retest reliability of the measure. Taken together, these results support the use of the BAS-2 in Brazilian cisgender gay and bisexual men and provide an initial understanding of body appreciation and other related constructs among this population.

RESUMO

PURPOSE: Investigate the efficacy of a dissonance-based (DB) intervention (i.e., the Body Project), during which some examples of intuitive eating were provided by peer leaders, in improving intuitive eating and targeting risk and protective factors for eating disorders (ED) among Brazilian women with body dissatisfaction. METHODS: Participants were randomized to a four-session DB intervention (n = 38) or assessment-only control (AOC) (n = 36), and completed validated measures assessing intuitive eating, body appreciation, self-esteem, body-ideal internalization, body dissatisfaction, negative affect, and disordered eating pre-intervention, post-intervention, and at 4- and 24-week follow-ups. RESULTS: The DB condition demonstrated significantly greater increases in intuitive eating, body appreciation and self-esteem scores compared to AOC from pre-intervention to post-intervention (between-condition Cohen's d = 0.73-0.98), 4-week (between-condition Cohen's d = 1.25-1.87) and 24-week follow-up (between-condition Cohen's d = 0.82-1.38). Also, the DB condition showed significantly greater decreases in body-ideal internalization, body dissatisfaction and disordered eating scores from pre-intervention to post-intervention (between-condition Cohen's d = 0.76-1.04), 4-week (between-condition Cohen's d = 1.27-1.71) and 24-week follow-up (between-condition Cohen's d = 1.04-1.19). Regarding negative affect, DB condition showed significantly greater reduction only at 24-week follow-up (between-condition Cohen's d = 0.60). CONCLUSION: Results reinforce the efficacy of DB interventions in reducing ED risk factors for young women and support the preliminary efficacy of these programs in improving intuitive eating, body appreciation, and self-esteem.

RESUMO

The utility of traditional eating disorder measures in the assessment of muscularity-oriented disordered eating has been questioned. To address this limitation, the Muscularity-Oriented Eating Test (MOET) was recently developed and validated in a sample of U.S. college men. We aimed to develop a multicultural Spanish-language version of the MOET for use in Latin American samples and validate its use in a sample of Argentinian college men. Combined translation procedures were used to develop a version suitable for different Spanish-speaking populations. A total of 235 students (Mage = 23.47, SD = 5.61) participated in this study by completing a survey including the MOET. A sub-sample (n = 121) completed the MOET again after 1 week. A confirmatory factor analysis of a re-specified model of the original single-factor MOET, allowing for residual correlation between items associated to dietary rules (items 4-12), resulted in an adequate fit (χ2/df = 2.10, CFI = 0.94, TLI = 0.93, RMSEA 0.05 [90% CI = 0.04, 0.06] SRMR = 0.08). Further, the multicultural Spanish-language version of the MOET yielded evidence of internal consistency (omega = 0.83, 95% CI [0.79, 0.88], Cronbach's α = 0.83), a 1-week Intraclass Correlation Coefficient was considered for test-retest reliability (ICC = 0.82), item analysis, convergent validity with measures of eating disorder psychopathology, body dissatisfaction and weight-related behaviors, as well as for divergent validity with an unrelated construct. The availability of a multicultural Spanish-language version of the MOET may have utility in both clinical and research efforts related to muscularity-oriented disordered eating among Latino men.

RESUMO

Despite increasing empirical interest in muscle dysmorphia (MD), a dearth of research has assessed this construct in sexual minority populations. In particular, the psychometric properties of one of the most widely used measures of MD symptoms-the Muscle Dysmorphic Disorder Inventory (MDDI)-have not been evaluated in sexual minority populations despite emerging evidence suggesting differential risk for MD symptoms across sexual orientation groups. In this study, we assessed the psychometric properties of the MDDI in a sample of 715 cisgender gay men and 404 cisgender lesbian women ages 18-50 years who participated in a large-scale national longitudinal cohort study of sexual and gender minority adults. The factor structure of the MDDI was examined in each sample using a two-step, split-sample exploratory and confirmatory factor analytic approach. Exploratory factor analysis supported a three-factor structure in both samples, which were confirmed by confirmatory factor analysis. Moreover, results supported the internal consistency reliability and convergent validity of the MDDI subscales in both samples. Cumulatively, these findings suggest that the MDDI is an appropriate measure of MD symptoms among cisgender gay men and cisgender lesbian women.

RESUMO

OBJECTIVE: Few prevention programs have been developed and empirically evaluated to address eating disorder (ED) and muscle dysmorphia (MD) symptoms in men. Furthermore, new strategies for the broad implementation of available programs are needed. We investigated the acceptability and efficacy of a dissonance-based (DB) intervention for Brazilian undergraduate men with body dissatisfaction to target risk and protective factors for ED and MD symptoms (the Body Project: More Than Muscles) after an online training for facilitators. METHOD: Participants were randomized to a two-session DB-intervention (n = 89) or assessment-only control (AOC) (n = 91), and completed validated measures assessing ED and MD risk and protective factors pre-intervention, post-intervention, and at 4- and 24-week follow-up post-intervention. RESULTS: Acceptability ratings were highly favorable. Regarding efficacy, the DB condition demonstrated significantly greater decreases in ED and MD risk factors compared to AOC from pre-intervention to 4-week (p-values <.05, between-condition Cohen's d = 0.35-1.10) and 24-week follow-up (p-values <.05, between-condition Cohen's d = 0.33-0.78). Results at post-intervention were not significant, with the exception that body appreciation showed significantly greater improvements in the DB condition (post-intervention: p < .01, between-condition Cohen's d = 0.40; 4-week: p < .001, between-condition Cohen's d = 0.80; and 24-week follow-up: p < .001, between-condition Cohen's d = 0.58). DISCUSSION: Results support the acceptability and efficacy of a DB-intervention delivered in-person after an online training for facilitators up to 24-week follow-up in Brazilian men.
