RESUMEN

Measures of beliefs and attitudes toward food have generally been limited to the measurement of more pathological eating attitudes (e.g., disordered eating). The Food Life Questionnaire (FLQ) and its short form (FLQ-SF) were developed to examine attitudes toward a broader range of foods; however, the factor structure of the FLQ-SF was not confirmed in any study with young women. In the present study, we performed a psychometric evaluation of the Brazilian Portuguese translation of the FLQ-SF in a sample of 604 women. We evaluated the factor structure using a two-step, split-sample exploratory and confirmatory factor analytic approach. Results supported a four-factor structure (i.e., weight concern, diet-health orientation, belief in a diet-health linkage, and food and pleasure) with 18 items (χ2/df = 2.09; CFI = 0.95; TLI = 0.94; RMSEA = 0.05 (90% CI = 0.04; 0.06; p > 0.05); and SRMR = 0.08). Additionally, we found good internal consistency for all FLQ-SF subscales (McDonald's ω = 0.79-0.89) and convergent validity with measures of feelings, beliefs, and behaviors involved in food attitudes. Collectively, these results support the use of the FLQ-SF in Brazilian women and provide a foundation to expand the literature on beliefs and attitudes toward food in this population.

RESUMEN

PURPOSE: To evaluate compulsive exercise, researchers often rely on the widely used Compulsive Exercise Test (CET). However, the measure has shown unstable factor structure in several validation studies and is not available in Portuguese for use in Brazil. We aimed to describe the translation and cultural adaptation of the CET to Brazilian Portuguese, to test several factor structures among Brazilian and US samples of men and women, to test measurement invariance across countries, and to evaluate its internal consistency. Furthermore, we sought to evaluate convergent validity, correlating the CET with a measure of eating disorder symptoms, and to compare compulsive exercise symptoms between countries. METHODS: Four models of the latent structure of the CET were tested using confirmatory factor analyses (CFAs), three-factor structure with 15 items, three-factor structure with 18 items, four-factor structure with 21 items, and the original five-factor structure with 24 items, in a sample of 1,531 young adults (601 Brazilians and 930 Americans), aged 18-35 years. RESULTS: A series of CFAs demonstrated that the three-factor structure with 15 items showed a better fit to the data. This model demonstrated good convergent validity and internal consistency. Results from the CET multigroup CFA showed evidence for the invariance at the configural, metric, and scalar levels across Brazilians and Americans. Furthermore, significant differences were found between Brazilians and Americans, with Brazilians demonstrating higher scores on the Avoidance and rule-driven behavior and Mood improvement subscales, whereas US participants scored higher on the Weight control exercise subscale. CONCLUSIONS: Results support the three-factor structure with 15 items to be used as a measure of compulsive exercise among Brazilians and Americans, allowing cross-cultural comparisons between these countries. LEVEL OF EVIDENCE: Level V, Cross-sectional, Psychometric study.

RESUMEN

Body image concerns related to weight or other dimensions of appearance are now prevalent on a global scale. This paper reviews the theoretical frameworks that account for the global similarities and regional differences in rates and presentation of body image concerns, as well as reviewing the extant data. Given the harmful consequences of body image concerns in terms of mental and physical health, their global burden is high. Interventions to mitigate these concerns at the individual and systemic level are warranted.

RESUMEN

OBJECTIVE: This systematic review evaluates and summarizes existing eating disorder (ED) prevention programs in Latin American countries. METHODS: A systematic literature search was conducted using the Cochrane Controlled Trial Register, PubMed, and Virtual Health Library databases up to and including July 31, 2022. All ED prevention studies published in English, Spanish or Portuguese were eligible, regardless of the study design, sample characteristics, and type of prevention programs. The Cochrane Collaboration Risk of Bias criteria were used to evaluate the quality of the included studies. RESULTS: Twenty-two studies were included. Most were pilot studies that were nonrandomized, had a high risk of bias, were from Mexico and Brazil, and employed selective interventions. Dissonance-based programs and social cognitive theory were the commonly used approaches in interventions, and most of them were tested in adolescent girls and women. Short follow-ups were used, varying from 1 to 6 months. Many found significant decreases after the intervention and/or at follow-up in ED/disordered eating risk behaviors/symptoms, negative affect, body-ideal internalization, and body image disturbances. CONCLUSIONS: This review highlights promising efforts to prevent EDs among Latin American countries. Some barriers in conducting research include funding restrictions, laws that do not allow remuneration or compensation for participants, and high costs of training. Nonetheless, the outcomes of the programs developed and evaluated so far are positive enough to merit further work on ED prevention. Efforts for future researchers should recruit samples with diverse characteristics, use robust designs and data analysis techniques, and expand the accessibility of prevention programs. PUBLIC SIGNIFICANCE STATEMENT: The development of effective eating disorder (ED) prevention programs that can be broadly implemented is a public health priority. Nevertheless, there is limited evidence regarding the characteristics of ED prevention programs and their efficacy among Latin American countries. In the present study, we reviewed existing ED prevention programs adopted in Latin America, described their characteristics and outcomes, noted the limitations of available programs, and discussed the implications of these findings for efforts to prevent the development of EDs in Latin America. The outcomes of the programs developed and evaluated so far are positive enough to merit the development and rigorous evaluation of future programs and their broad dissemination in Latin American countries. PROSPERO registration number CRD42021275245.


OBJETIVO: Esta revisión sistemática evalúa y resume los programas de prevención de trastornos de la conducta alimentaria (TCA) existentes en los países de América Latina. MÉTODOS: Se realizó una búsqueda bibliográfica sistemática utilizando las bases de datos del Registro Cochrane de Ensayos Controlados (Cochrane Controlled Trial Register), PubMed y Virtual Health Library hasta el 31 de julio de 2022 inclusive. Todos los estudios de prevención de TCA publicados en inglés, español o portugués fueron elegibles, independientemente del diseño del estudio, las características de la muestra y el tipo de programas de prevención. Se utilizaron los Criterios de Riesgo de Sesgo de la Colaboración Cochrane para evaluar la calidad de los estudios incluidos. RESULTADOS: Se incluyeron veintidós estudios. La mayoría eran estudios piloto no aleatorizados, tenían un alto riesgo de sesgo, eran de México y Brasil, y empleaban intervenciones selectivas. Los programas basados en la disonancia y la teoría cognitiva social fueron los enfoques comúnmente utilizados en las intervenciones, y la mayoría de ellos se probaron en niñas y mujeres adolescentes. Se utilizaron seguimientos cortos, que variaron de uno a 6 meses. Muchos encontraron disminuciones significativas después de la intervención y / o en el seguimiento en los síntomas de TCA/Conductas Alimentarias de Riesgo, afecto negativo, internalización de la figura ideal y trastornos de la imagen corporal. CONCLUSIONES: Esta revisión destaca los esfuerzos prometedores para prevenir los TCA entre los países de América Latina. Algunas barreras en la realización de investigaciones incluyen restricciones de financiamiento, leyes que no permiten la remuneración o compensación para los participantes y los altos costos de capacitación. No obstante, los resultados de los programas desarrollados y evaluados hasta ahora son lo suficientemente positivos como para merecer un mayor trabajo en la prevención de los TCA. Los esfuerzos para futuros investigadores deben reclutar muestras con características diversas, utilizar diseños robustos y técnicas de análisis de datos, y ampliar la accesibilidad de los programas de prevención.

RESUMEN

INTRODUCTION: The Strengthening and Stretching for Rheumatoid Arthritis of the Hand (SARAH) program is a personalized, progressive 12-week exercise program for people with hand problems due to rheumatoid arthritis (RA). Patients are provided with two guidance documents, the 'Patient Exercise Booklet' and the 'Personal Exercise Guide', to continue the exercises independently at home. OBJECTIVE: This study aimed to translate and culturally adapt the SARAH protocol into Brazilian Portuguese and validate its content. METHODS: The guidance documents 'Patient Exercise Booklet' and 'Personal Exercise Guide' of the SARAH program were translated and culturally adapted to Brazilian Portuguese. The content validity was obtained by calculating the content validity index (CVI). RESULTS: The Brazilian version of the SARAH protocol reached semantic, idiomatic, conceptual, and cultural equivalences. The CVI was greater than 0.8, corresponding to a satisfactory index. The verbal comprehension was 4.9, showing good verbal comprehension of the target population. CONCLUSION: The Brazilian Portuguese version of the SARAH protocol is available to Brazilian people with compromised hands due to RA with satisfactory content validity.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

OBJECTIVES: To describe the translation and cultural adaptation, and evaluate the psychometric properties of the Body Image in Pregnancy Scale when applied to Brazilian pregnant women. BACKGROUND: Poor body image of pregnant women is associated with negative outcomes for maternal and child health. However, there is a lack of psychometric studies aiming to evaluate the body image experiences during pregnancy. METHODS: A methodological study was carried out with 187 Brazilian pregnant women. We performed translation and cross-cultural adaptation (evidence of content validity), and evaluated the psychometric properties (factorial validity through principal component analysis, discriminant validity, and estimated internal consistency) of the Brazilian version of the Body Image in Pregnancy Scale. RESULTS: The scale items presented semantic, idiomatic, cultural, and conceptual equivalences, showing evidence of content validity. Principal component analysis resulted in a 6-factor structure with 35 items which showed an adequate adjustment of the scale among Brazilian pregnant women. Adequate estimated internal consistency (Cronbach's α = .88) was found. The Brazilian version was not able to discriminate pregnant women from different gestational age. CONCLUSION: The Brazilian version of the Body Image in Pregnancy Scale showed evidence of content validity, factorial validity, and estimated internal consistency.

RESUMEN

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. LEVEL OF EVIDENCE: Level I, randomized controlled trial. ReBEC (Brazilian Registry of Clinical Trials; available at http://www.ensaiosclinicos.gov.br/ ) number of registration: RBR-2f57cs.

RESUMEN

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.

RESUMEN

There is a lack of psychometric studies on scales aiming to evaluate the drive for muscularity in women. This study aimed to test whether the Drive for Muscularity Scale (DMS) yielded reliable and valid scores for assessing the drive for muscularity construct in young adult women. A cross-sectional study was conducted among 242 Brazilian adult women. Exploratory factor analysis, convergent validity, estimated internal consistency, and test-retest reliability of the DMS's scores were examined. The results of the exploratory factor analysis upheld the original unidimensional structure of the DMS for Brazilian women. The scale presented a significant but weak association with body mass index and risk behaviors for eating disorders. Adequate internal consistency and 2-week test-retest reliability were found. Future psychometric analyses (convergent and discriminant validity) of the DMS are encouraged to further our understanding of drive for muscularity in women, especially to confirm its unidimensional factor structure. Future research avenues also include examining the reliability and validity of the DMS's scores among women from various cultures.

RESUMEN

This study verified the performance probabilities by mixed martial arts rounds by the same athletes, doing paired comparisons of time-motion and actions before and after 10 y. The sample was composed of 845 Ultimate Fighting Championship rounds of 45 athletes separated into before (M1, age range 34-44 y) and after (M2, age range 44-54 y). Motor-control (takedowns, submissions, chokes, locks, strike actions to the head, and body and leg strikes attempted and landed) and time-motion (high and low intensities and standing and ground times) analyses were done. The main results showed significant differences (P ≤ .05) in total strikes landed (M1 22 [13; 34] > M2 18 [10; 31.7]), total strikes attempted (M1 41 [24.5; 62] > M2 35 [21; 48]), single head strikes attempted (M1 19 [9; 34.5] > M2 16.5 [9; 28]), single body strikes landed (M1 1 [0; 4] > M2 1 [0; 2]), single body strikes attempted (M1 2 [0; 5] > M2 1 [0; 3]), takedowns attempted (M1 1 [0; 2] > M2 1 [0; 2]), standing combat time (M1 2:10.28 [1:38.95] > M2 1:55.56 [1:32.17]), and low-intensity time (M1 2:11.45 [1:38.95] > M2 1:56.26 [1:31.89]). Variables that increased the probability to be associated with over the years were body strikes landed, head strikes landed, total strikes landed, and single strikes attempted, whereas body strikes attempted, head strikes attempted, total strikes attempted, and submission attempted had a negative association with mixed martial arts years of experience. Therefore, M2 athletes should be focused on standing combat time combined with strikes-landed actions, targeting the head-it has the highest potential performance probability and avoid unsuccessful body-strike attempts and submissions-which has the lowest potential performance probability over 10 years.

RESUMEN

The Tripartite Influence Model posits that parents, peers and media influences mediated by internalization and appearance social comparison are predictors of body dissatisfaction, a key risk factor for eating disorders. However, the Tripartite Influence Model has not been tested in Brazil where the people are known to have high levels of body image and appearance concerns. This study aimed to test an adapted Tripartite Influence Model of body dissatisfaction and disordered eating behaviors among Brazilian women. A sample of 741 undergraduate students (Mage = 23.55 years, SD = 4.09) completed measures of sociocultural influences, internalization of body ideal, social appearance comparison, body dissatisfaction, muscularity dissatisfaction, disordered eating and body change behaviors. Structural equation modeling analyses indicated that the proposed etiological model for Brazilian women has good fit indexes (χ2(2064) = 6793.232; p = 0.0001; χ2/gl = 3.29; CFI = 0.82; PCFI = 0.79; RMSEA = 0.056 [IC90% = 0.053-0.057]). Parent and media influences were related with both internalization and social comparison, while peer influence with social comparison. A full mediation model was found, with both internalization and social comparison contributing to body dissatisfaction. Finally, body dissatisfaction was associated with disordered eating behaviors. The findings inform the importance of considering cultural aspects that influence body image and eating behaviors, and highlight the validity of the proposed etiological model for Brazilian women, that can be used for research and clinical purposes.

RESUMEN

PURPOSE: To compare body attitudes of pregnant women in various body mass index categories, during different gestational periods and under gestational risk conditions, as well as to analyze the association of the study variables with the body attitudes of pregnant women. METHODS: We included 386 pregnant women in all gestational periods, aged 18 to 46 years (mean 29.32 ± 6.04 years ), who attended prenatal care in the public and private sectors of a city in Southeastern Brazil, excluding women with incomplete data. The instruments for assessment were "Body Attitudes Questionnaire", "Critério de Classificação Econômica Brasil", and a sociodemographic questionnaire. In addition, anthropometric and obstetric data were collected. Descriptive, comparative, and correlational statistical analyses were performed. RESULTS: The body attitudes of pregnant women were similar in all pregnancy trimesters (F = 0.39; p = 0.9). Negative body attitudes increased gradually among low weight (108.2 ± 12.5), appropriate weight (116.2 ± 16.0), overweight (125.1 ± 14.3), and obese (132.9 ± 16.4) groups, and among pregnancy women with normal (120.0 ± 17.1) and high-risk pregnancies (124.9 ± 16.7). The sociodemographic, economic, and obstetric variables did not influence the variance of body attitudes. The body mass index explained 11.3% of the variance of body attitudes in pregnant women. CONCLUSIONS: Nutritional status and risk conditions showed an association with negative body image and should therefore be evaluated in pregnant women for a better maternal and child health.

RESUMEN

The body image of pregnant women is an issue that should be further investigated by professionals in the area, especially in view of the fact that maternal and infant health has gained such prominence. The scope of this integrative review is to analyze the literature relating to body image and body dissatisfaction among pregnant women. Research was based on articles extracted from the Scopus, PubMed, BVS and PsycINFO databases, by cross-referencing "pregnancy" with the keywords "body image" and "body dissatisfaction." Once the inclusion and exclusion criteria had been adopted, forty studies were analyzed. These produced inconclusive data about body dissatisfaction during pregnancy. Symptoms of depression, low self-esteem, an inadequate approach towards healthy eating and weight gain above recommended limits have been associated with a negative body image. The contradictory findings could be related to the different instruments used to measure body image. In view of the possible impact that a negative body image can have on maternal and infant health during pregnancy, it is recommended that further investigations are made, in particular related to the development of a specific tool to evaluate the body image of pregnant women.

RESUMEN

PURPOSE: To evaluate psychometric assessment of Stunkard Figure Rating Scale (FRS) for Brazilian male population. METHODS: The sample was composed of a control group (94 students) and a clinical group (20 eating disordered patients). Two questionnaires were applied: the FRS and the Eating Attitudes Questionnaire-26. Weight, height, and body mass index (BMI) were collected in the control group (self-reported) and clinical group (measured). Body dissatisfaction (BD) was calculated by subtraction of ideal body (IB) from the current body (CB) score. The concurrent validity was assessed through the analysis of the correlation between the CB and BD scores and the BMI and the body weight. The discriminant validity was achieved by measurements of association between the groups studied and the scales CB, IB and BD. Reliability was assessed by the comparison of the score averages at two moments and by the intraclass coefficient correlation. RESULTS: The questionnaire had a correlation higher than 0.67 for the measures of weight and BMI. Regarding the CB, IB and BD scores, a significant difference was not observed between the clinical and the control group. There was no difference between the scores for BD at the two moments analyzed. CONCLUSIONS: The FRS is stable and capable of correlating with anthropometric measures. Nevertheless, for this population the questionnaire was unable to distinguish between the two groups analyzed.
