The ORTO-15 is a commonly used screening instrument for symptoms of Orthorexia Nervosa (ON), an obsessive overconcern with healthy eating. However, its limitations have been evidenced in several published factorial models. We analyzed the psychometric properties of seven different ORTO-15 factorial models using data from Brazilian adult participants ( n = 1455; 71.4% women; M age = 29.5, SD = 8.9 years) from the country's five macro-regions who answered online questions for sample characterization and completed the Portuguese version of the ORTO-15 containing 15 items. We tested the fit of each model separately, analyzing data for men and women with separate confirmatory factor analysis, and using the Weighted Least Squares Mean and Variance Adjusted estimation method and goodness-of-fit indices. We also calculated the average variance extracted and the alpha ordinal and omega coefficients to analyze the convergent validity and reliability of the factors. None of the models tested presented adequate properties of validity and reliability. Although we found some acceptable reliability coefficients, they do not guarantee the validity of the data. Future investigators should be cautious when choosing the ORTO-15 for ON screening., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

The Preference for Intuition and Deliberation in Food Decision-Making Scale (E-PID) was developed to evaluate both intuitive and deliberative food decision-making within a single instrument. However, its psychometric properties have only been assessed among German-speaking participants. The main aim of the present study was to evaluate evidence of validity and reliability of the E-PID among 604 Brazilian adult women. Exploratory ( n = 289) and confirmatory factor analyses ( n = 315) were conducted to evaluate the factor structure of the E-PID. Convergent validity was assessed correlating the E-PID with measures of eating behaviors (Tree-Factor Eating Questionnaire-18), intuitive eating (Intuitive Eating Scale-2), and a measure of beliefs and attitudes towards food (Food-Life Questionnaire-SF). McDonald's Omega coefficient (ω) was used to test the internal consistency of the E-PID. Results from an exploratory and confirmatory factor analysis supported a two-factor structure with seven items. We found good internal consistency (McDonald's ω = 0.77-0.81). Furthermore, the E-PID demonstrated adequate convergent validity with measures of intuitive, restrictive, emotional and uncontrolled eating, and beliefs and attitudes towards food. Results support the use of the E-PID as a measure of intuition and deliberation in food decision-making among Brazilian adult women, expanding the literature on eating decision-making styles.

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 (χ 2 / 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.

This study investigated which foods are most saliently judged as healthy and unhealthy in Brazil and Germany and the reasons for these judgements. Dietary guidelines in the two countries differ in that those in Brazil are based on a food processing classification rather than nutrient profiling, whereas dietary guidelines in Germany do not include the processing level of food. In an online study with 355 lay adults (Brazil n = 205, Germany n = 150), we explored which foods are listed as healthy and unhealthy using a free-listing method. The main reasons for these healthiness judgements were then identified with a one or two-word phrase and compared between countries. Saliency analysis was conducted to identify the 15 most salient healthy and unhealthy foods in each country. Principles of content analysis were used to assess the reasons why these 15 items were listed as most salient by the participants. Results showed that both Brazilians and Germans listed mostly natural or minimally processed food (e.g. fruits, vegetables, grains, fish and milk) as healthy, whereas types of convenience and fast food, sweets and other ultra-processed foods (e.g. chocolate, soda, French fries, pizza and hamburger) were the most salient unhealthy items listed in both countries. Differences in culturally relevant items listed in each country are discussed. Further, in both countries, despite differences in their dietary guidelines, food healthiness judgements for the most salient items listed relied heavily on the nutritional content of food, reinforced the 'good/healthy' and 'bad/unhealthy' dichotomy, and were centred on benefits or harms to the body (e.g. prevention or cause of diseases and weight control). The similarity of food healthiness judgements between the two countries, together with their agreement with conventional health claims and dietary guidelines, suggest that lay Brazilian and German adults are knowledgeable about the general concepts of 'healthy' and 'unhealthy' food. Finally, these findings suggest that rather than just providing more nutritional information, policymakers and health professionals need to take into account the multiple psychosocial and environmental determinants of eating in these countries., (© 2023 British Nutrition Foundation.)

Prior studies on perceived healthiness of foods have often compared nutrient and hedonic claims, neglecting comparisons to a control condition. The effect of food claims focusing on the food processing level has received considerably less research attention, although food processing has been included in dietary guidelines in Brazil. Thus, the present study aimed to explore the effect of a control and processing claim, additionally to the effects of a nutrient. and hedonic claim, on perceptions related to a food item typically considered "less healthy" (chocolate cake). We further compared these effects between Brazil and Germany, a country where food processing is currently not included in dietary guidelines. A total of 634 lay adults were recruited in a cross-sectional online study and randomised to see the photo of a piece of cake with one of the four different claim conditions and to report their health-related perceptions of the cake. The main analyses included two-way ANCOVAs (4 claims x 2 countries) for each dependent variable controlled for gender, age and level of hunger; followed by post hoc tests. Overall, results revealed that in both countries, the claims highlighting nutrients or processing aspects rendered the perceptions of the cake healthier compared to the control claim. These effects were more pronounced among Brazilian than among German participants. Food-related perceptions mostly did not differ between the hedonic and control claim and did not differ at all between the nutrient and processing claims. In conclusion, it is noteworthy that, even for an inherently considered "less healthy food item" (chocolate cake) nutrient and processing claims increase healthiness perceptions. While our findings may imply that in both countries lay people are highly susceptible to nutrient claims, food processing aspects seem to be similarly relevant., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

Instruments to evaluate psychosocial determinants of fruit and vegetable (F&V) consumption among adolescents are scarce, and there appears to be only one instrument - unnamed and unvalidated - that investigates determinants derived from theories of social psychology targeting the frequency of F&V consumption among adolescents. The scope of this paper was to present the process of cultural adaptation and factor validation of this instrument al-lowing its use in studies with Brazilian adolescents. The cross-cultural adaptation process was accomplished and the final version - named Psychosocial Influence Scale for Fruit and Vegetable Consumption among Adolescents (PSI-FAVES) - was tested with 429 students (58% female) using McDonald's omega (ω) reliability and Confirmatory Factor Analysis (CFA) as analytical methods. The final version required refinement and the instrument showed adequate overall reliability (ω=0.86) and good fit of the data to the previously elaborated model (CFI=0.955; TLI=0.951 and RMSEA (90%CI) =0.043 (0.038-0.049)), being the first systematically validated instrument to investigate psychosocial determinants of F&V consumption among adolescents.

Objectives: This study aimed to evaluate the impact of a nutritional behavioral intervention on intuitive eating (IE) scores of overweight non-dialysis-dependent women with chronic kidney disease and to investigate the relationship of IE scores with demographic, nutritional, and quality of life parameters in this group., Design and Methods: This is a prospective noncontrolled clinical trial of a behavioral multisession group intervention for dietary management. Each group comprised five to eight participants in 14 weekly or biweekly sessions lasting about 90 minutes each. The IE principles were discussed during the meetings. The IE scale 2, translated and adapted to the study population, with a four-factor model was applied to assess IE attitudes. The 36-Item Short-Form Health Survey questionnaire was applied to assess health-related quality of life., Results: Of the 33 patients who began participation in the study, 23 patients (median [interquartile range]: age = 62.0 years [58.0-68.0]; 52.2% with diabetes; body mass index = 32.6 kg/m 2 [30.2-39.3]; estimated glomerular filtration rate = 28.0 mL/min/1.73 m 2 [22.0-31.0]) completed the intervention. Except for the IE subscale Body-Food Choice Congruence, the IE total score and all its subscales (Unconditional Permission to Eat, Eating for Physical Rather than Emotional Reasons, Reliance on Hunger and Satiety Cues, and Body-Food Choice Congruence) improved after the intervention. In a cross-sectional analysis, more intuitive eaters were older and had better scores for health-related quality of life., Conclusions: The nutritional behavioral intervention embracing IE principles was effective to improve IE attitudes for this group of chronic kidney disease patients. These results are promising and may contribute to a paradigm change in the strategies to enhance motivation and adherence to dietary recommendations in this population., (Copyright © 2022 National Kidney Foundation, Inc.

Objective: The aim of this study was the cross-cultural adaptation of the Eating Belief Questionnaire (EBQ)-an instrument that assesses positive, negative, and permissive eating beliefs in relation to binge eating episodes-in its shorted version of 18 questions, into Brazilian Portuguese, for female teenagers., Methods: Conceptual, semantic, cultural and operational equivalence of the items were evaluated. The semantic and cultural equivalence involved 12 bilingual people and 12 experts in eating behavior. Operational equivalence consisted of applying the transcultural adapted version of the EBQ-18 to 20 girls with a mean age of 17.55 (SD=1.00) years. Item's clarity and understanding were assessed by the Content Validity Coefficient., Results: Questions 5, 6, 11, 14, 15, 16, 17 and 18, with adequate classification percentage for all equivalences, were not altered. The other items were adapted according to the committee's suggestions and by consensus among researchers. The adapted version of the EBQ-18 in Brazilian Portuguese displayed good content validity coefficient for clarity (CVC=0.975) and comprehension (CVC=0.971); except for item 3, all items had values between 0.88 and 1.00., Conclusion: The Brazilian Portuguese version of the EBQ-18 had a good understanding by the adolescent public when it comes to investigate the role of dietary beliefs in the maintenance of binge eating episodes. Future studies with adolescents are recommended, jointly assessing risk for and presence of eating disorders in significant clinical and non-clinical samples, as well as its psychometrics properties.

Food cultures can play a role in health and well-being. This raises the questions of whether nation boundaries unite the food cultures of different regions and ethnic groups, what characterises food cultures from very different parts of the world, and what similarities and differences exist. The present study aimed to investigate these questions with regard to eating traditions and modern eating practices. In this cross-sectional study, we recruited 3722 participants from ten countries - Brazil, China, France, Germany, Ghana, India, Japan, Mexico, Turkey, and the USA. Participants represented 25 regional and ethnic groups. They were queried about 86 traditional and modern facets of their food cultures in interviews, paper-pencil and online questionnaires. First, hierarchical cluster analysis suggested nine distinct clusters of food cultures - the food cultures of the Brazilian, Chinese, Ghanaian, Indian, Japanese, Mexican, Turkish, African and Latin US American samples, and of European descendants. Interestingly, for seven of the ten investigated countries, nation boundaries united food cultures. Second, each of the nine food culture clusters was characterised by a unique pattern of traditional and modern eating practices. Third, the nine food culture clusters varied more in their traditional eating practices than their modern eating practices. These results might promote a better understanding of the link between food cultures and health and well-being that goes beyond nutrients. For instance, food cultures might be linked to well-being via strengthening people's sense of cultural identity. Moreover, the present results contribute to a better understanding of the complex interplay between food and culture, and could help in developing culturally competent interventions to improve diet and reduce the risk of eating-related diseases., (Copyright © 2022 Elsevier Ltd.

Obesity-related prejudice and discrimination may have a source in health professionals and students. The objective was to assess anti-fat attitudes among Brazilian nutrition undergraduates who reported demographic data, weight, height and responded the Antifat Attitudes Test (AFAT) and the Brazilian Silhouette Scales to assess body image satisfaction and perception. Total and subscales of AFAT scores were compared among categories using the Mann-Whitney U test. Associations of participants' characteristics with the AFAT were analyzed using multiple linear regression. Total AFAT score was positively associated with male sex (ß: .13; p < .001), age (ß: .06; p < .001), educational institution outside capital (ß: .03; p < .05), private institutions (ß: .08; p < .001); and negatively associated with income (ß: -.05; p = .006), participants who perceived themselves with increased BMI (ß: -.15; p < .001) and those at the third year of course (ß: -.05; p = .041). Subscales scores were positively associated with male sex and age; and negatively associated with those who perceived themselves heavier. They have anti-fat attitudes especially if they were man, older, from private institutions, are at the beginning of the course, and have lower household income - and less weight bias if they perceived with increased BMI.

In most Western countries, children and adolescents do not eat the recommended amount of fruits and vegetables (FVs). Theoretical frameworks on social psychology of eating, such as the Reason Action Approach, Social Cognitive Theory, and Theory of Normal Conduct have been applied to understand how psychosocial variables can explain FV intake. However, considering those predictors is still rare on the understanding of FV intake among adolescents (particularly in Brazil) despite its importance within eating behavior. Therefore, this study explored important psychosocial determinants of weekly frequency of FV intake among Brazilian adolescents in a model testing socioeconomic status (SES) and body mass index (BMI). A cross-sectional design was performed with 429 students (58% female), mean age 14.45 (SD 1.86). Key variables of theoretical framework on social psychology of food were investigated by structural equation modeling. The model included self-efficacy, attitudes, and social norms (with its subcomponents descriptive and injunctive) as psychosocial predictors of weekly frequency of FV intake along with SES and BMI. An instrument developed for Brazilian Portuguese was used to collect psychosocial variables as well as to verify FV reported intake. The total model explained 45.5% of weekly frequency of FV intake, and self-efficacy was the only significant psychosocial determinant (λ = 0.51, p = 0.001). SES also showed an important effect on the model (λ = 0.21, p = 0.001), while for BMI no significance was observed. In conclusion, the model was adequate to understand psychosocial determinants of weekly frequency of FV intake for Brazilian adolescents, with self-efficacy and SES as the major determinants of this eating behavior., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Moraes, Alvarenga, Moraes and Cyrillo.)

Objective: To perform the cross-cultural adaptation of the Fat Talk Questionnaire into Brazilian Portuguese with focus on adolescent girls., Methods: The steps taken in this research were: conceptual and item equivalence, semantics, operational. The conceptual and item equivalence was performed by researchers in the field of Nutrition and body image; semantics involved translators fluent in English and Portuguese (n=3) and experts (n=19) in body image and eating behavior. Step 3 included 32 female adolescents (15 and 18 years), who answered the translated and adapted version to assess comprehension by the target audience., Results: Of the 14 items, six were considered adequate by the experts and 3 items required minimal language adjustments. Five items needed broader changes for cultural and idiomatic adaptation. The back-translation was approved by the original authors. The average response time by the adolescents was 3.5 minutes, with no queries., Conclusion: The scale was translated and adapted to Brazilian Portuguese aimed at female adolescents, showing satisfactory results in the translation process, conceptual, semantic and operational equivalence. Analyses of external validity, measurement equivalence and reproducibility were also required.

Background: Childhood and adolescent obesity is a worldwide public health concern. The New Moves program aims to change eating behavior (EB) and physical activity (PA)., Objective: To evaluate the effectiveness of an intervention and predictors of better outcomes relating to EB and PA levels., Design and Setting: Secondary data from a cluster randomized controlled trial in 10 public schools in São Paulo, Brazil., Methods: 270 female adolescents, aged 12 to 14 years, were analyzed. Participation levels were categorized as presence in 1 to 9 sessions or 10 to 17 sessions, or control. Effectiveness was evaluated through improvement in disordered EB (DEB) and EB. Predictors of better outcomes relating to PA levels were evaluated through clustering of individual characteristics that affected changes in PA scores., Results: Participation level was not significantly associated with changes in DEB or EB. Girls with higher body mass index percentile (BMI-P) percentile tended to have increases in sedentary lifestyles through the program. Girls with less body image dissatisfaction presented higher increases in daily PA. Girls with higher BMI-P percentile and higher self-esteem showed reductions in sedentary lifestyles. The program seemed to have more effect on daily PA among older girls than among younger girls., Conclusions: This program could be used as a structured action plan in schools, with the aims of improving eating behaviors and physical activity, in addition to promoting self-acceptance. The results indicate the importance of evaluating determinants of adherence, as these metrics might influence the effectiveness and future design of lifestyle programs.

Understanding the motives influencing food intake is indispensable for effective dietary recommendations aimed at promoting healthy eating in an integrative way. The objective of this study was to evaluate food choice motives across two socioeconomically different cities in Brazil. A cross-sectional study with a convenience sample (n = 473) of adults living in both places was evaluated. Food choice motives were assessed by The Eating Motivation Survey (TEMS) with 15 dimensions, and economic classifications were made according to the Brazilian Economic Classification Criteria (CCEB). Data analysis used both a general linear model (GLM) and a Structural Equation Model (SEM) adjusted for age, ethnicity, income and educational degree. Participants were mainly women (74.6%) with a mean age of 36.6 years. Cities were not invariant (Δχ2 = 314.165, p < 0.001) and two distinct prediction models for food choice motives emerged. Fit indices indicate acceptable model fit for both low (CFI = 0.911; TLI = 0.898; RMSEA = 0.041) and high socioeconomic status groups (CFI = 0.808; TLI = 0.717; RMSEA = 0.081). Although cities differ in the prediction models for food choice motives, we demonstrated that there are two main networks of predictors: one related to social context predictors of food choice motives and another related to hedonic-oriented ones. Particularly, hedonic-oriented motives (i.e., pleasure) were the most relevant predictors to the group of high socioeconomic status followed by social context predictors (traditional eating and sociability). On the other hand, the group of low socioeconomic status had most of its predictors related to social context (i.e., visual appeal, traditional eating, sociability, social norms and social image) and also price, but this last one was the least important among the most important predictors., (Copyright © 2020 Elsevier Ltd.

This study aimed to validate a short version of the Disordered Eating Attitude Scale (DEAS-s). To this end, 2,902 adult individuals answered the original DEAS and informed age, weight, and height. Data were analyzed using the full-information factor analysis and Item Response Theory (IRT) analysis. Exclusion criteria retained items with adequate values of commonality and factor loadings. Estimation of IRT parameters, the Item Characteristic Curve (ICC), and test information guided the selection of the best quality items. The final model adjustment was evaluated using Root Mean Square Error of Approximation (RMSEA), Standardized Root Mean Square Residual (SRMSR), Comparative Fit Index (CFI), and Tucker-Lewis Index (TLI). The eating attitudes on each level of DEAS-s were described. The analyses were performed on R software and Microsoft Excel version 2013. As results, six items were excluded because of the low communalities and factor loadings, and one more was excluded because of an overlapping on the ICC. The remaining 17 items explained 0.53 of the total variance and had an adequate goodness-of-fit (RMSEA = 0.05; SRMSR = 0.05; CFI = 0.98; TLI = 0.98). The information test is more accurate between the scores 0 and +3. Scores higher or equal to 1.5 identified individuals with disordered eating attitudes. Women, older individuals, and those with a higher body mass index presented more disordered eating; thus, the one-dimensional and short version of DEAS showed a suitable adjustment and may contribute to properly evaluate disordered eating in diverse populations.

Objective: To identify the frequency of disordered eating (DE) and unhealthy weight control behaviors (UWCB) among adolescents and associations with age, sex, actual weight status, perceived weight status, and body image dissatisfaction., Methods: Cross-sectional study of 1,156 adolescents. DE was assessed using a specific self-report questionnaire, UWCB by specific behaviors that were not typically recommended for weight management, and body dissatisfaction by Stunkard's silhouettes., Results: The frequency of DE was 17.3%, and that of UWCB, 31.9%; 80.1% of participants were dissatisfied with body image. Perception of oneself as overweight was associated with 1.795-fold odds of DE. Those with UWCB had 7.389-fold odds of DE, while DE increased the odds of UWCB 7.280-fold. Girls, participants who perceived themselves as overweight, and those who reported body dissatisfaction were 2.266, 2.381, and 1.752 times more likely to have UWCB, respectively., Conclusion: A high prevalence of UWCB and a moderate prevalence of DE behaviors was found in adolescents from the city of São Paulo, Brazil. Those who perceived themselves as overweight had more DE and UWCB, and both behaviors were related. UWCB was more common in girls and among those dissatisfied with their bodies.

Across the world, there has been a movement from traditional to modern eating, including a movement of traditional eating patterns from their origin culture to new cultures, and the emergence of new foods and eating behaviors. This trend toward modern eating is of particular significance because traditional eating has been related to positive health outcomes and sustainability. Yet, there is no consensus on what constitutes traditional and modern eating. The present study provides a comprehensive compilation of the various facets that seem to make up traditional and modern eating. Specifically, 106 facets were mentioned in the previous literature and expert discussions, combining international and interdisciplinary perspectives. The present study provides a framework (the TEP10 framework) systematizing these 106 facets into two major dimensions, what and how people eat, and 12 subdimensions. Hence, focusing only on single facets of traditional and modern eating is an oversimplification of this complex phenomenon. Instead, the multidimensionality and interplay between different facets should be considered to gain a comprehensive understanding of the trends, consequences, and underlying factors of traditional and modern eating.

Brazil is undergoing a rapid nutrition transition with unfavorable effects on dietary healthiness. To counteract this trend, knowledge about individual drivers of consumption is needed that go beyond environmental factors. The Eating Motivation Survey represents a comprehensive measure of such individual drivers, assessing 15 eating motives, such as choosing food for health reasons or eating because of a good taste. The aim of this study was to examine the psychometric properties and validity of a Brazilian Portuguese version of The Eating Motivation Survey. In total, 442 participants from the general adult population living in the state of São Paulo, Brazil filled in an online survey. Results showed that the model, including 15 motive factors and 45 items, had a reasonable model fit. Moreover, factor loadings and corrected item-scale correlations were generally good. Fourteen out of the 15 motive scales had a reliability above 0.60. Results also confirmed convergent validity. These results demonstrate that the Brazilian Portuguese version of The Eating Motivation Survey is generally reliable and valid to assess individual drivers of eating behavior in Brazil., (Copyright © 2019 Sproesser, Moraes, Renner and Alvarenga.)

Obesity is associated with psychosocial problems like stigma, discrimination, and bias. Studies have found that nutritionists and nutrition students display negative attitudes and biases toward obese individuals. This study examined the existence of nutrition students' bias toward obese individuals. The students answered questionnaires by completing on-line forms with demographic data and self-reported weight and height and were assigned to one of four randomly selected hypothetical cases of patients referred to a nutritionist after receiving a diagnosis of lactose intolerance (normal weight man; normal weight woman; obese man; and obese woman). Except for weight, body mass index (BMI), and daily energy intake, all information on diet, habits, and health conditions were identical for profiles of the same sex. The questionnaire included questions on the indication of procedures and approaches during the consultation, consultation time, counseling strategies, dietary and health evaluation, and students' affective and behavioral reactions. Three hundred and thirty-five students participated, mostly women, with mean BMI of 23kg/m². Patient's weight influenced consultation time and students' perceptions and treatment approaches and strategies. The study revealed biases and negative attitudes mainly involving the students' perceptions and reactions to obese patients, and obese women generally received the worse evaluations.

Obese individuals are often blamed for their own condition and the targets of discrimination and prejudice. The scope of this study is to describe the cross-cultural adaptation to Brazilian Portuguese and the validation of the Antifat Attitudes Test - specifically developed for evaluation of negative attitudes toward the obese individual. The scale has 34 statements distributed in three subscales - Social/Character Disparagement (15 items), Physical/Romantic Unattractiveness (10 items) and Weight Control/Blame (9 items). The method involved the translation of the scale; evaluation of the conceptual, operational and item equivalence; evaluation of the semantic equivalence using the paired t test, the Pearson correlation coefficient and the intraclass correlation coefficient (ICC); internal consistency evaluation (Cronbach's alpha) and test-retest reliability (ICC) and Confirmatory Factor Analysis - after application in 340 college students in the area of health. The results showed good global internal consistency and reliability (α 0.85; CCI 0.83), and factor analysis showed that the original subscales can be kept in the adaptation, and therefore the scale adapted to the Brazilian-Portuguese version is valid and useful in studies to explore negative attitudes toward obese individuals.

Understanding why people eat what they eat is essential for developing nutritional guidelines capable of modifying inadequate and dysfunctional eating patterns. Such understanding can be assessed by specific instruments, amongst which The Eating Motivation Survey (TEMS) allows the identification of factors that determine motivations for eating and food choices. The aim of this study is to present the cross-cultural adaptation of the short version of TEMS for use in studies in the Brazilian population. The process involved conceptual and item equivalences; semantic equivalence by 2 translators, 1 linguist, 22 experts (frequency of response understanding), and 23 bilingual individuals (with response comparisons by the paired t-test, Pearson correlation coefficient, and intra-class correlation coefficient); and operational equivalence, performed with 32 individuals. The measurement equivalence corresponding to psychometric properties is under way. All equivalences showed satisfactory results for the scale's use in Brazil, thus allowing application of TEMS to assess motivations for eating choices in the Brazilian context.

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 (M age  = 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 (χ 2 (2064) = 6793.232; p = 0.0001; χ 2 /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., (Copyright © 2017 Elsevier Ltd.
