Examination of the factorial model of a scale developed to assess body satisfaction in the Brazilian context: a study with people 18 to 40Â years old
Purpose Confirmatory factor analysis was employed to investigate an instrument developed to assess body satisfaction of
Brazilian women and men and to identify participants’ body satisfaction level.
Methods Brazilian young adults completed the Body Satisfaction Situational Scale and a sociodemographic questionnaire.
A total of 1481 individuals (female = 1035; male = 446) aged between 18 and 40 years old participated in the study. Factorial,
convergent and discriminant validity and reliability were evaluated. An invariance test was performed across sexes
using multi-group analysis. The prevalence of body satisfaction among participants was calculated using the final models
of the instrument.
Results The complete model of the scale (23 items and four factors) was invariant across sexes, but it did not fit the samples
even after refinement. Therefore, a theoretical investigation of the scale content was performed based on literature. Thus,
a reduced model composed of two factors and ten items was found for each sex. These models showed good validity and
reliability to independent samples. About prevalence, most of the women were not at all satisfied with body fat and most of
the men were slightly satisfied with body musculature. Further, women and men were moderately satisfied with their face,
hair, and skin.
Conclusion A reduced model of the instrument for women and another for men showed adequate indices of construct validity
and reliability to samples. The most participants were not very satisfied with their bodies. The results can be useful to
develop protocols aiming to promote body satisfaction.

Strategies for eating and body change among Brazilian women and men
Our study was conducted to adapt the Body Image and Body Change Inventory (BIBCI) for Portuguese; to evaluate the BIBCI's psychometric properties in samples of university students; to calculate the prevalence of strategies for eating and body change among students; and to evaluate the impact of demographic, social, and anthropometric characteristics on the BIBCI subscales.info:eu-repo/semantics/publishedVersio
What are the motives underlying Brazilians' food choices? An analysis of the Food Choice Questionnaire and its relationship with different sample characteristics
ABSTRACT: The first aim of this study was to evaluate the psychometric properties of the Food Choice Questionnaire (FCQ)—using the original model—in a sample of 1480 Brazilian adults (69.5% female). The second aim was to rank the reasons underlying the participants' food choices using average FCQ scores and 95% confidence interval. The third aim was to evaluate the relationship between food choice motives and sample characteristics using multiple logistic regression and odds ratios. The validity, the invariance across different groups, and the reliability of the FCQ were confirmed for the sample. Sensory appeal and price emerged as the most important reasons, while ethical concern was the least valued. The factors associated with greater odds of choosing food for specific reasons were being older, female, and a student; practicing physical activity; dieting frequently; self-rating eating quality as good; having a higher body mass index; and having low income.
Practical Applications
Assessing food choice is a complex task, as it encompasses several factors, such as sensory characteristics, health status, income, culture, lifestyle, and cognitive-affective issues; therefore, the use of appropriate tools should be encouraged. The set analyses followed confirmed that the FCQ was an adequate instrument to evaluate the reasons for food choice of the participants who valued strongly the sensory aspects of the foods and presented specific characteristics (e.g., diet practice) that may influence their decisions. These findings may guide future research and clinical interventions aimed at producing food choices that are more oriented to health and well-being.FAPESPinfo:eu-repo/semantics/publishedVersio
Cross-cultural adaptation and psychometric investigation of the palatable eating motives scale (PEMS) for a sample of Brazilian adults
Highly palatable foods and beverages can significantly stimulate appetite through the reward system leading to hedonic
hunger. Investigating palatable food is important, especially in Brazil, which lacks this type of study based on psychometric
instruments such as the Palatable Eating Motives Scale (PEMS). 1. To adapt the PEMS from English to Portuguese; 2. To
evaluate the psychometric properties of the PEMS for a sample of young adults; 3. To verify the influence of sex, age, and
body mass index (BMI) on motives for consuming highly palatable foods and drinks. The PEMS was cross-culturally adapted
and translated into Portuguese. Psychometric properties included analyses of validity (factorial, convergent, discriminant,
and external) and reliability. A hypothetically causal structural model was constructed to verify the relationship between
individuals’ characteristics and PEMS factors. 1031 people participated in the study [female = 61.6%, mean age = 25.5
(SD = 5.3) years]. A PEMS model proposed in Turkish contexts showed adequate adjustment to the sample. Females and
younger individuals reported consuming highly palatable foods and drinks more frequently for Coping; Enhancement; and
other reasons compared to males and older individuals. Individuals with a higher BMI indicated that they consumed these
foods and drinks more frequently only for Coping. The Portuguese version of the PEMS was presented and the data obtained
for the sample were valid and reliable. Sex, age, and BMI are important characteristics to investigate consumption of highly
palatable foods and drinks.FAPESPinfo:eu-repo/semantics/publishedVersio
Relationships between three eating behaviors and nine motives for food choices among brazilian adults: A structural equation model
We examined the relationships between three eating behaviors and nine motives
underlying food choices made by Brazilian adults. Using participant responses to the
short version of the Three-Factor Eating Questionnaire and the Food Choice
Questionnaire, we investigated eating behaviors (cognitive restriction, uncontrolled
eating, and emotional eating) and motives for food choices (health, mood, convenience,
sensory appeal, natural content, price, weight control, familiarity, and ethical concern).
We used a structural equation model to test relationship pathways (β), with eating
behaviors as independent variables and motives for food choices as dependent variables.
Participants were 1297 individuals (69.5% female) with a mean age of 25.0 years
(SD = 5.8). We confirmed the validity and reliability of the questionnaires in this sample.
Restrictive eating behavior was significantly related to motives of health (β = .415), mood (β = .127), natural content (β = .364), weight control (β = .681), and ethical
concern (β = .161). Emotional eating behavior was related to motives of mood (β =
.277), health (β = .137), and natural content (β = .136). Uncontrolled eating
behavior was related to motives of convenience (β = .226), sensory appeal (β = .121),
price (β = .153), and familiarity (β = .090). We believe these findings can now help
design future research and clinical interventions for managing people’s risky eating
behaviors and promoting beneficial food choices.info:eu-repo/semantics/publishedVersio
A Portuguese Adaptation of the Teruel Orthorexia Scale and a Test of Its Utility with Brazilian Young Adults
The aims for this study were to perform a Portuguese language cross-cultural adaptation of the Teruel Orthorexia Scale (TOS) and to evaluate the scale's psychometric properties, including verifying the frequency of behaviors characteristic of orthorexia nervosa and healthy orthorexia, among a group of Brazilian gym users. First, we adapted the Spanish version of the TOS to the Brazilian Portuguese language following international protocols to guarantee idiomatic, semantic, conceptual, and cultural equivalence. Then participants completed both the new Portuguese version of the TOS and a socioeconomic questionnaire. Among our sample of 226 young Brazilian adults (63.7% men; M age = 28.8, SD = 5.1 years), we assessed the bi-factorial model of the TOS through factorial, convergent, and discriminant validity, reliability, and factorial invariance. We calculated the mean scores of the TOS factors and the frequency of behaviors of both orthorexia nervosa and healthy orthorexia. The new Portuguese version was well understood by participants, and the TOS bi-factorial model presented adequate psychometric properties and showed invariance in independent subsamples and in men and women. The mean scores were different between sexes only for orthorexia nervosa, with women obtaining higher values. The frequency of orthorexia nervosa behaviors was 5.3% and of healthy orthorexia was 41.2%. Based on these findings, the Brazilian Portuguese version of the TOS can be a useful tool for investigating orthorexia-like behaviors in future research.info:eu-repo/semantics/publishedVersio
Impact of body and orofacial appearance on life satisfaction among Brazilian adults
Aims
1. to elaborate a general model of physical appearance taking into account body image (BI)
and orofacial appearance (OA) components; and 2. to evaluate the impact of BI and OA on
life satisfaction among Brazilian adults.
Methods
This is a cross-sectional observational study. The cognitive, behavioral, affective, and satisfaction/
dissatisfaction aspects of BI, the satisfaction and psychosocial impact of OA, and life
satisfaction were evaluated by self-reported psychometric scales. Principal Component
Analysis and Parallel Analysis were performed. Structural equation models were elaborated
to estimate the impact of BI and OA on life satisfaction. The fit of the models was verified
and the significance of the path estimates (β) was evaluated using z-tests (α = 5%).
Results
A total of 1,940 individuals participated in the study (age: mean = 24.8, standard deviation =
5.7 years; females = 70.1%). In the male sample, three physical appearance factors were
retained (OA, cognitive and behavioral components of BI, and affective and satisfaction/dissatisfaction
components of BI). In the female sample, two factors were retained (OA and all
components of BI). All factors had significant impact on life satisfaction (β = |0.26|-|0.48|,
p<0.001) in both samples. Individuals dissatisfied with BI and OA had lower levels of life satisfaction.
For men, the affective and satisfaction components of BI had a greater impact on
life satisfaction (β = 0.48, p<0.001) than the other factors (β =] -0.30;-0.25[, p<0.001). For
women, both BI and OA had a similar impact (BI: β = -0.30, p<0.001; OA: β = -0.32,
p<0.001). Conclusion
BI and OA formed distinct clusters in the physical appearance evaluation. Physical appearance
was perceived differently by men and women, fostering discussion about the sociocultural
construction of the body. BI and OA had a significant impact on life satisfaction and
should be considered in assessment and treatment protocols.info:eu-repo/semantics/publishedVersio
Psychometric properties of the World Health Organization Quality of Life Instrument-Abbreviated version in Portuguese-speaking adults from three different countries
To evaluate the validity, reliability and invariance of the World Health Organization Quality of Life Instrument-Abbreviated version (WHOQOL-Bref) in Portuguese-speaking adults from three different countries.Objetivo: Avaliar a validade, a confiabilidade e a invariância do
World Health Organization Quality of Life instrument-Abbreviated
version (WHOQOL-Bref) em adultos de três diferentes paÃses de
lÃngua portuguesa.
Métodos: Um total de 4.020 indivÃduos brasileiros, portugueses e
moçambicanos participaram do estudo. A amostra total foi dividida
em quatro amostras: pacientes brasileiros (n = 1.120), estudantes
brasileiros (n = 1.398), estudantes portugueses (n = 1.165) e
estudantes moçambicanos (n = 337). A validade fatorial do
WHOQOL-Bref foi avaliada por meio de análise fatorial confirmatória.
As validades convergente e discriminante do instrumento foram
avaliadas utilizando a variância média extraÃda (VEM) e o quadrado
do coeficiente de correlação de Pearson (r2), respectivamente. A
confiabilidade composta e o coeficiente alfa ordinal foram utilizados
como medidas de confiabilidade. As invariâncias métrica, escalar e
estrita do WHOQOL-Bref foram avaliadas por análise multi-grupos
em subamostras independentes (dentro de cada amostra) e
somente entre Brasil e Portugal (transnacional), porque o modelo
configuracional de Moçambique era diferente.
Resultados: O modelo original do WHOQOL-Bref não apresentou
bom ajustamento para as amostras. Diferentes itens foram
excluÃdos para ajustar o instrumento em cada amostra (modelos
diferentes para o WHOQOL-Bref entre amostras brasileiras,
portuguesas e moçambicanas). A VEM e o r2 não foram adequados;
entretanto, a confiabilidade do WHOQOL-Bref foi boa, exceto na
amostra moçambicana. A invariância foi encontrada apenas em
subamostras independentes.
Conclusão: Os modelos ajustados do WHOQOL-Bref apresentaram
adequada validade fatorial e invariância em subamostras
independentes. A não invariância transnacional do WHOQOL-Bref
revela a influência da cultura na operacionalização do construto
qualidade de vida.FAPESP; Conselho Nacional de Desenvolvimento CientÃfico

European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30: factorial models to Brazilian cancer patients
Objective To evaluate the psychometric properties of the seven theoretical models proposed in the literature for European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), when applied to a sample of Brazilian cancer patients. Methods Content and construct validity (factorial, convergent, discriminant) were estimated. Confirmatory factor analysis was performed. Convergent validity was analyzed using the average variance extracted. Discriminant validity was analyzed using correlational analysis. Internal consistency and composite reliability were used to assess the reliability of instrument. Results A total of 1,020 cancer patients participated. The mean age was 53.3±13.0 years, and 62% were female. All models showed adequate factorial validity for the study sample. Convergent and discriminant validities and the reliability were compromised in all of the models for all of the single items referring to symptoms, as well as for the "physical function" and "cognitive function" factors. Conclusion All theoretical models assessed in this study presented adequate factorial validity when applied to Brazilian cancer patients. The choice of the best model for use in research and/or clinical protocols should be centered on the purpose and underlying theory of each model.FAPESPinfo:eu-repo/semantics/publishedVersio
Social Appearance Anxiety Scale: A psychometric investigation and evaluation of the influence of individual characteristics on social appearance anxiety in Brazilian adults who practice physical exercise
fntroduction: Evaluating signs of anxiety related to body appearance is becoming
increasingly important in contemporary society and, in this sense, the Social
Appearance Anxiety Scale (SAAS) seems an interesting alternative of measurement.
Objectives: To evaluate the psychometric properties of the Portuguese version
of the SAAS when applied to Brazilian adults who practice physical exercise and
verify the influence of individual characteristics on participants’ social appearance
anxiety.
Methods: This was a cross-sectional study conducted online. The participants
completed the SAAS and a demographic questionnaire. The psychometric
properties of the SAAS one-factor model were evaluated using confirmatory
factor analysis. A structural model was built for men and women to verify the
influence of individual characteristics of the participants on social appearance
anxiety.
Results: 1,495 individuals participated in the study (70.8% women; mean age  =  29.5,
SD  =  8.9  years). The data obtained with the SAAS presented good indicators of
validity and reliability for both genders (CFI  >  0.97, TLI  >  0.97, SRMR  =  0.04, α  >  0.97,
ω  >  0.85). For both men and women, greater levels of social appearance anxiety
were observed among younger participants, who had a higher body mass index,
self-reported an eating disorder, and perceived a change in their body after the
onset of the COVID-19 pandemic. For women specifically, higher income and
having started physical exercise more recently were associated with greater levels
of social appearance anxiety.
Conclusion: The findings supported the validity and reliability of the data obtained
with the SAAS and revealed that when investigating social appearance anxiety in uture research and clinical protocols, specific individual characteristics should
be considered.info:eu-repo/semantics/publishedVersio
