RESUMEN

Introducción: La sensibilidad a la ansiedad es un constructo poco conocido, y que sin embargo tiene un importante valor clínico, por ser un potente predictor de los trastornos de ansiedad, tanto en niños, como adolescentes y adultos. En Perú existen pocas pruebas psicométricas que evalúan la ansiedad en niños, y menos aún sobre sensibilidad a la ansiedad. Objetivo: En esta investigación se realiza un análisis psicométrico del Índice de Sensibilidad para Niños con la finalidad de estimar la validez y la confiabilidad de esta prueba que no ha sido aplicada en población peruana. Método: Se tomó una muestra no probabilística de 568 escolares de entre 8 y 12 años de cinco instituciones educativas de la ciudad de Arequipa, en Perú. Los datos se procesaron mediante el Análisis Factorial Confirmatorio de Grupo Múltiple utilizando el programa R. Resultados: Los resultados confirmaron una estructura de dos factores: Miedo a las sensaciones corporales y Miedo a síntomas mentales y sociales, con índices de confiabilidad aceptables calculados mediante la prueba Omega de McDonald. Conclusión: Se concluye que la prueba es válida y confiable, pero se sugiere profundizar en el análisis psicométrico de este instrumento.

Introduction: The anxiety sensitivity is a few known theoretical construct, although it has a relevant clinical worth, because it is a powerful predictor of the anxiety disorders, so as in children, as in adolescents and adults. Moreover, in Peru there are few psychometric tests that assess children anxiety, and even fewer about anxiety sensitivity. Objective: In this research, it was made a psychometric analysis of the Childhood Anxiety Sensitivity Index (CASI) with the aim to estimate the validity and reliability of this test that has not been applied in Peruvian population. Method: A non-probabilistic sample of 568 students among 8 and 12 years old was assessed of five elementary school from Arequipa City, in Peru. The data was processed with multiple group confirmatory factor analysis by R program. Results: The results confirm a two factors structure: Fear of body sensations and Fear of mental and social symptoms, with acceptable reliability indexes calculated by McDonald's Omega Test. Conclusion: The conclusion is that the CASI is valid and reliable; perhaps it is suggested to investigate another psychometric properties of this test.

RESUMEN

(1) Background: Increased stress and study overload during adolescence could be related to academic burnout. Anxiety sensitivity of students seems to affect burnout levels, while emotional intelligence enables emotion management under stressful conditions. The objective of this study is to analyze the roles of anxiety sensitivity and emotional intelligence in academic burnout. (2) Methods: In this quantitative cross-sectional study conducted in Spain, the sample comprised 1287 high school students aged 14 to 18 who filled out the Maslach Burnout Inventory-General Survey, the Spanish version adapted for high school students of the Anxiety Sensitivity Index-3, and Brief Emotional Intelligence Inventory. (3) Results: Anxiety sensitivity was significantly higher in cynicism and emotional exhaustion. Furthermore, the mediation analysis showed that high anxiety sensitivity directly affected student exhaustion, cynicism, and efficacy levels. These effects were mediated mainly through stress management but also through the effect of stress management on mood, both emotional intelligence factors. (4) Conclusions: The academic changes that occur during high school hinder engagement and performance. Promoting the development of emotional skills would enable young people to manage their emotions when they become overwhelming and diminish their lack of interest and exhaustion in the classroom.

RESUMEN

BACKGROUND: The novel 2019 SARS2-Coronavirus (COVID-19) has had a devastating physical health, mental health, and economic impact, causing millions of infections and hundreds of thousands of deaths. While COVID-19 has impacted the entire world, COVID-19 has disproportionately impacted low-income countries, particularly in South America, causing not only increased mortality but also increased associated mental health complaints. Anxiety sensitivity (AS), reflecting fear of anxiety-related physical sensations, may be particularly important to understand COVID-19 mental health effects among Latinx individuals in South America (Argentina). Past work suggests that Latinx individuals report greater somatization of mental health symptoms, and AS has been specifically linked to greater mental health symptoms. Yet, to date, no work has examined AS as a vulnerability factor for the negative mental health effects of COVID-19. METHOD: Therefore, the current manuscript examined the association of AS with COVID-19 worry, functional impairment, anxiety, and symptom severity across two samples of adults in Argentina: a community sample (n = 105, M age = 38.58, SD = 14.07, 69.5% female) and a clinical sample comprised of individuals with an anxiety disorder (n = 99, M age = 34.99, SD = 10.83, 66.7% female). RESULTS: Results from the current study provide support for AS as a potential vulnerability factor for COVID-19-related mental health problems across both samples, and these effects were evident over and above the variance accounted for by age, sex, pre-existing medical conditions, and COVID-19 exposure. CONCLUSIONS: These data identify AS as a potential intervention target to reduce COVID-19 mental health burden among adults in Argentina.

RESUMEN

Abstract The transdiagnostic model allows explaining and developing treatments based on the etiology and maintenance factors of comorbid psychopathologies; however, the relationships between its explanatory variables still require investigation. The purpose of this paper was to develop a structural model that includes these transdiagnostic variables: positive and negative affect, intolerance to uncertainty and anxiety sensitivity, in emotional problems such as anxiety and depression. Quantitative research was carried out with an explanatory cross-sectional design in which a structural network of relationships between constructs was defined using a diagram of paths and structural equations. 486 Colombians between the ages of 20 and 40 were intentionally randomly sampled. The following instruments were used to assess the fitting of the model: Positive and Negative Affect Scale (PANAS), Anxiety Sensitivity Index-3 (ASI-3), Intolerance of Uncertainty Scale (IUS), Beck Anxiety Inventory (BAI) and Beck Depression Inventory, second edition, Spanish version (BDI-II). The results showed significant correlations between transdiagnostic and symptomatic variables (depression and anxiety symptoms), using an adjusted model that explained the predictive capacity of anxiety sensitivity with anxiety symptoms, and intolerance of uncertainty with depression symptoms, both transdiagnostic variables associated with positive and negative affect as predictors of anxious and depressive emotional symptoms (R2 = .74).

Resumen El modelo transdiagnóstico permite explicar y desarrollar tratamientos basados en la etiología y factores mantenedores de las psicopatologías comórbidas, no obstante, las relaciones entre sus variables explicativas aún requieren investigación. El objetivo del presente trabajo fue desarrollar un modelo estructural que incluye las variables transdiagnósticas: afecto positivo y negativo, intolerancia a la incertidumbre y sensibilidad a la ansiedad, en problemas emocionales como ansiedad y depresión. Se llevó a cabo una investigación cuantitativa con un diseño transversal explicativo en el cual se definió una red estructural de relaciones entre constructos mediante un diagrama de senderos y ecuaciones estructurales. Se conformó una muestra no probabilística intencional de 486 colombianos entre 20 y 40 años. Para evaluar el ajuste del modelo se utilizaron los siguientes instrumentos: Positive and Negative Affect Scale (PANAS), Anxiety Sensitivity Index-3 (ASI-3), Intolerance Uncertainty Scale (IUS), Beck Anxiety Inventory (BAI) y Beck Depression Inventory, second edition, Spanish version (BDI-II). Los resultados indicaron correlaciones significativas entre las variables transdiagnósticas y las sintomáticas (síntomas de depresión y ansiedad), mediante un modelo ajustado que permitió explicar la capacidad predictiva de la sensibilidad a la ansiedad con los síntomas de ansiedad, y la intolerancia a la incertidumbre con los síntomas de depresión, ambas variables transdiagnósticas asociadas al afecto positivo y negativo como predictores de los síntomas emocionales ansiosos y depresivos (R2 = .74).

RESUMEN

Abstract Introduction: Anxiety sensitivity plays a prominent role in the etiology of anxiety disorders. This construct has attracted widespread interest from experts and researchers. The Anxiety Sensitivity Index (ASI-3) is the most common scale for measuring anxiety sensitivity. Objective: To analyze the psychometric properties and factor structure of the ASI-3 in Iranian student samples. Methods: 220 students (135 women, 85 men) from Kermanshah University of Medical Sciences were selected by the convenience sampling method to evaluate the psychometric properties and analyze the factor structure of the ASI-3. The subjects were also asked to complete the Acceptance and Action Questionnaire-II (AAQ-II), Whiteley Index, Intolerance of Uncertainty, and Neuroticism scales. LISREL and SPSS were used to analyze the data. Cronbach's alpha and correlation coefficients were calculated and confirmatory factor analysis was conducted. Results: The results of the confirmatory factor analysis revealed a three-factor structure with physical, cognitive, and social components (comparative fit index = 0.94; normed fit index = 0.91; root mean square error of approximation = 0.09). The ASI-3 had positive and significant correlations with health anxiety (0.59), intolerance of uncertainty (0.29), and neuroticism (0.51). Furthermore, the ASI-3 had a negative and significant correlation with the AAQII (-0.58). Cronbach's alpha coefficients for the whole scale and for the physical, cognitive, and social concerns factors were 0.90, 0.74, 0.79, and 0.78, respectively. The invariance of the index was significant compared to the original English version. Conclusion: In general, the results support the adequacy of the psychometric properties of the Persian version of the ASI-3. Theoretical and applied implications will be discussed.

Resumo Introdução: A sensibilidade à ansiedade desempenha um papel proeminente na etiologia dos transtornos de ansiedade. Esse construto tem atraído grande interesse entre especialistas e pesquisadores. O Anxiety Sensitivity Index (ASI-3; em português, Escala de Sensibilidade à Ansiedade) é a medida mais utilizada para medir sensibilidade à ansiedade. Objetivo: Analisar as propriedades psicométricas e a estrutura fatorial do ASI-3 em estudantes iranianos. Métodos: Para avaliar as propriedades psicométricas e analisar a estrutura fatorial do ASI-3, 220 estudantes (135 mulheres, 85 homens) da Kermanshah University of Medical Sciences, Irã, foram selecionados via amostragem por conveniência. Eles foram solicitados a completar os seguintes instrumentos: Acceptance and Action Questionnaire-II (AAQ-II), Whiteley Index, Intolerance of Uncertainty e Neuroticism. Os programas LISREL e SPSS foram utilizados para analisar os dados. Alfa de Cronbach e coeficientes de correlação foram calculados, e foi realizada análise fatorial confirmatória. Resultados: Os resultados da análise fatorial confirmatória revelaram uma estrutura de três fatores, incluindo componentes físicos, cognitivos e sociais [comparative fit index (CFI) = 0,94; normed fit index (NFI) = 0,91; root mean square error of approximation (RMSEA) = 0,09]. O ASI-3 demonstrou correlações positivas e significativas com ansiedade em relação à saúde (0,59), intolerância à incerteza (0,29) e neuroticismo (0,51). Além disso, o ASI-3 teve uma correlação negativa e significativa com o AAQII (-0,58). Os coeficientes alfa de Cronbach para toda a escala e para os fatores preocupação física, cognitiva e social foram 0,90, 0,74, 0,79 e 0,78, respectivamente. A invariância do índice foi significativa em relação à versão original. Conclusão: Em geral, os resultados sugerem que as propriedades psicométricas da versão persa do ASI-3 são adequadas. Implicações teóricas e práticas serão discutidas.

RESUMEN

BACKGROUND: A growing number of studies are questioning the validity of current DSM diagnoses, either as "discrete" or distinct mental disorders and/or as phenotypically homogeneous syndromes. In this study, we investigated how symptom domains in patients with a main diagnosis of obsessive-compulsive disorder (OCD), panic disorder (PD) and social anxiety disorder (SAD) coaggregate. We predicted that symptom domains would be unrelated to DSM diagnostic categories and less likely to cluster with each other as severity increases. METHODS: One-hundred eight treatment seeking patients with a main diagnosis of OCD, SAD or PD were assessed with the Dimensional Obsessive-Compulsive Scale (DOCS), the Social Phobia Inventory (SPIN), the Panic and Agoraphobia Scale (PAS), the Anxiety Sensitivity Index-Revised (ASI-R), and the Beck Depression and Anxiety Inventories (BDI and BAI, respectively). Subscores generated by each scale (herein termed "symptom domains") were used to categorize individuals into mild, moderate and severe subgroups through K-means clusterization and subsequently analysed by means of multiple correspondence analysis. RESULTS: Broadly, we observed that symptom domains of OCD, SAD or PD tend to cluster on the basis of their severities rather than their DSM diagnostic labels. In particular, symptom domains and disorders were grouped into (1) a single mild "neurotic" syndrome characterized by multiple, closely related and co-occurring mild symptom domains; (2) two moderate (complicated and uncomplicated) "neurotic" syndromes (the former associated with panic disorder); and (3) severe but dispersed "neurotic" symptom domains. CONCLUSION: Our findings suggest that symptoms domains of treatment seeking patients with OCD and anxiety disorders tend to be better conceptualized in terms of severity rather than rigid diagnostic boundaries.

RESUMEN

Abstract Background: The relationship between impulsivity and nonsuicidal self-injury (NSSI) has been revealed in several mental disorders other than phobias. Objectives: The purpose of this study was to examine the relationships among impulsivity, anxiety sensitivity, and NSSI characteristics in patients with phobias, and to compare these relationships with healthy controls. Methods: The sample of this study consisted of outpatients (n = 109) who had been diagnosed with social phobia, agoraphobia or simple phobia in addition to healthy individuals (n = 51) serving as the control group. Data collection tools were the socio-demographic form, the Barratt Impulsivity Scale (BIS-11), the Inventory of Statements About Self-Injury (ISAS), and the Anxiety Sensitivity Index (ASI-3). Results: Mean BIS-11 and ASI-3 scores in the social phobia and agoraphobia groups were found to be significantly higher than those in the control group. In addition, a positive correlation was found between ISAS and cognitive anxiety sensitivity scores in the agoraphobia and simple phobia groups. Discussion: The study revealed a positive correlation between cognitive anxiety sensitivity and NSSI in both the agoraphobia and simple phobia groups. The results of this study indicate that anxiety sensitivity may play a regulatory role between impulsivity and NSSI in some sub-groups of phobia.

RESUMEN

O transtorno de pânico (TP) é caracterizado pela presença de ataques súbitos de ansiedade e sensação de medo intenso. Embora haja tratamento efetivo com medicações e terapia cognitivo-comportamental (TCC), muitos pacientes tratados apresentam resposta parcial e tendem à cronicidade. A sensibilidade à ansiedade (SA) é um constructo multidimensional que expressa preocupações físicas, sociais e cognitivas da ansiedade, considerada uma tendência específica a reagir com medo aos sintomas de ansiedade. A SA tem sido associada à gênese e à manutenção dos sintomas do TP, porém ainda são escassos estudos que avaliam se a TCC em grupo (TCCG) modifica tal condição. Os objetivos deste estudo foram: 1) avaliar o impacto da TCCG na SA em pacientes com TP; 2) verificar a associação entre as características sociodemográficas e clínicas (comorbidades, uso de medicação, gravidade do TP) relacionadas à SA; 3) verificar as variáveis clínicas relacionadas à mudança da SA após a TCCG; 4) analisar a SA e suas dimensões como preditor de resposta à TCCG. Trata-se de um ensaio clínico controlado para avaliação da SA em pacientes com TP que realizaram 12 sessões de TCCG comparados ao grupo controle sem a intervenção. A gravidade dos sintomas foi avaliada antes e depois da TCCG no grupo intervenção e uma vez no grupo controle. Utilizou-se a Escala de gravidade do TP (PDSS), a Impressão Clínica Global (CGI), a Hamilton Ansiedade (HAM-A), o Inventário de Ansiedade de Beck (BAI) e o Inventário de Depressão de Beck (BDI). Para avaliar a SA, foi utilizada a Escala de Sensibilidade à Ansiedade-Revisada (ESA-R) com quatro fatores: fator 1 − medo de sintomas respiratórios e cardiovasculares; fator 2 − medo de descontrole cognitivo; fator 3 − medo de que as reações à ansiedade sejam observadas publicamente; fator 4 − medo de sintomas gastrintestinais. O estudo foi aprovado pelo Comitê de Ética em Pesquisa do Hospital de Clínicas de Porto Alegre (nº 14-0379). Os pacientes assinaram o termo de consentimento livre e esclarecido (TCLE). A amostra foi composta por 89 sujeitos, com média de idade de 37,9 (DP=10,6) anos. Observou-se associação significativa entre a SA mais elevada em pacientes com comorbidade com agorafobia e sintomas mais elevados de ansiedade e de depressão. Um total de 37 (42%) pacientes participou do grupo intervenção e 52 (58%) pacientes do grupo controle. Houve melhora significativa em todos os sintomas específicos do TP, da ansiedade geral e dos sintomas depressivos. A SA também sofreu redução significativa em todos os fatores após a intervenção quando comparada aos escores iniciais, com tamanho de efeito (TE) de moderado a grande. Quando comparada a SA do grupo controle e do grupo intervenção após a TCCG, os escores da ESA-R diminuíram significativamente em todos os fatores e no total. Ou seja, a SA modifica-se com a TCCG tanto em termos de intragrupo intervenção quanto em termos de escores do grupo controle. Os resultados deste estudo confirmaram que a relação entre a SA é maior em pacientes com TP mais graves. Também foi evidenciada a eficácia da TCCG na redução das dimensões física, cognitiva e social da SA, confirmando a hipótese do impacto positivo da TCCG para a modificação desse quadro.

Panic disorder (PD) is characterized by the presence of sudden attacks of anxiety and intense fear sensation. Although there are effective treatments with medications and cognitivebehavioral therapy (CBT), many treated patients present partial response and tend to chronicity. Anxiety sensitivity (AS) is a multidimensional construct that expresses physical, social and cognitive anxiety concerns, considered a specific tendency to react with fear to the symptoms of anxiety. AS has been associated with the genesis and maintenance of PD symptoms, but there are still few studies evaluating whether CBT in group (CBT-G) modifies such condition. The objectives of this study were: 1) to evaluate the impact of CBT-G on AS in patients with PD; 2) to verify the association between sociodemographic and clinical characteristics (comorbidities, medication use, severity of PD) related to AS; 3) to verify the clinical variables related to the change in AS after CBT-G; 4) to analyze AS and its dimensions as a predictor of response to CBT-G. This is a controlled clinical trial for the evaluation of AS in patients with PD who performed 12 sessions of CBT-G compared to the control group without the intervention. The severity of the symptoms was evaluated before and after the CBT-G in the intervention group and once in the control group. We used the PD Severity Scale (PDSS), Clinical Global Impression (CGI), Hamilton Anxiety (HAM-A), Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI). In order to evaluate the AS, the Anxiety Sensitivity Index-Revised (ASI-R) was used with four factors: factor 1 - fear of respiratory and cardiovascular symptoms; factor 2 - fear of cognitive uncontrol; factor 3 - fear that reactions to anxiety could be publicly observed; factor 4 - fear of gastrointestinal symptoms. The study was approved by the Research Ethics Committee of the Hospital de Clínicas of Porto Alegre (nº 14-0379). Patients signed the informed consent form (TCLE). The sample consisted of 89 subjects, with a mean age of 37.9 (SD = 10.6) years. A significant association was observed between the highest AS in patients with comorbidity with agoraphobia and higher anxiety and depression symptoms. A total of 37 (42%) patients participated in the intervention group and 52 (58%) patients in the control group. There was a significant improvement in all the specific symptoms of PD, general anxiety and depressive symptoms. AS also had a significant reduction in all factors after the intervention when compared to the initial scores, with moderate to large effect size (ES). When compared to AS of the control group and the intervention group after the CBT-G, ASI-R scores decreased significantly in all factors and in the total. That is to say, AS is modified with CBT-G both in terms of intragroup intervention and in terms of scores of the control group. The results of this study confirmed that the relationship between AS is higher in patients with more severe PD. The effectiveness of CBT-G in reducing the physical, cognitive and social dimensions of AS was also evidenced, confirming the hypothesis of the positive impact of CBT-G for the modification of this condition.

RESUMEN

El objetivo fue construir un modelo de regresión múltiple para investigar la relación entre ansiedad social, sensibilidad a la ansiedad, rasgo de ansiedad y miedo a la evaluación negativa, y comparar hombres con mujeres. La investigación fue cuantitativa, no experimental, correlacional y transversal. Se evaluó a 689 adolescentes entre 14 y 19 años (M=16.45; DE=1.11), a través de la escala de Ansiedad Social para Adolescentes (SAS-A), la subescala Ansiedad-Rasgo del Inventario de Ansiedad Rasgo-Estado (STAI), la versión breve de escala de Miedo a la Evaluación Negativa (BFNE) y el Índice de Sensibilidad a la Ansiedad-3 (ASI-3). El género femenino presentó mayor media en ansiedad rasgo con tamaño de efecto pequeño (d=-.27). Las correlaciones fueron positivas entre bajas y moderadas. La correlación parcial y semiparcial más alta fue entre SAS-A y ASI. Se construyó un modelo de regresión válido y estadísticamente significativo y explicó el 41.2% de la varianza de la ansiedad social (R2=.412) con tamaño de efecto grande.

The objective was to build a multiple regression model to investigate the relationship between social anxiety, anxiety sensitivity, trait anxiety and fear of negative evaluation, and to compare men and women. The research was quantitative, not experimental, correlational and cross-sectional. 689 adolescents between 14 and 19 years (M=16.45; SD=1.11) were evaluated, through the Social Anxiety Scale for Adolescents (SAS-A), the trait subscale of the Trait Anxiety Inventory-State (STAI), the Brief Fear of Negative Evaluation Scale (BFNE) and Anxiety Sensitivity Index-3 (ASI-3) were applied. Female gender showed higher mean in trait anxiety with small effect size (d=-.27). Correlations were positive from low to moderate. The higher partial and semipartial correlation was between SAS-A and ASI. A valid regression model and statistically significant was constructed and explained 41.2% of the variance of social anxiety (R2=.412) with large effect size.

RESUMEN

OBJECTIVES: Anxiety sensitivity (AS) is related to the development and maintenance of posttraumatic stress disorder (PTSD) among cigarette smokers, and is also implicated in the amplification of acute nicotine withdrawal symptoms. The present study sought to examine the role of nicotine withdrawal in moderating the association between AS and PTSD symptom severity among a sample of treatment-seeking smokers with PTSD. METHOD: Participants (n = 117) were enrolled in a randomized controlled trial for the treatment of PTSD and nicotine dependence. Cross-sectional data were randomly sampled from three different study time points. A series of multiple regression models were tested. RESULTS: Results revealed main effects of both AS and withdrawal severity on PTSD severity after controlling for gender, assessment time-point, negative affectivity, and biochemically verified smoking (expired carbon monoxide). The interaction of AS and withdrawal was also significant, and appeared to be specific to PTSD avoidance and hyperarousal symptoms. However, contrary to expectations, the association between AS and PTSD symptoms was only significant at relatively lower levels of nicotine withdrawal. CONCLUSIONS: These findings highlight the complex interplay between AS, nicotine withdrawal, and their synergistic effect in terms of the exacerbation of PTSD symptomology.

RESUMEN

OBJECTIVE: The purpose of this study was to examine the reliability and the convergent validity of the Children Anxiety Sensitivity Index (CASI) with DSM-IV anxiety disorder symptoms, by comparison with the Screen for Child Anxiety Related Emotional Disorders (SCARED), in a community sample of Brazilian children and adolescents. METHODS: Children and adolescents from five schools were selected from a larger study that aimed to assess different aspects of childhood anxiety disorders. All participants completed the CASI and the SCARED. RESULTS: This study supported the reliability of the CASI total score. Girls reported higher total anxiety sensitivity scores than boys and there were no differences in total anxiety sensitivity scores between children and adolescents. This study showed moderate to high correlations between the CASI scores with SCARED scores, all correlations coefficients being positive and significant. CONCLUSIONS: Our findings demonstrate an appropriate reliability and evidence of convergent validity in the CASI in a sample of Brazilian children and adolescents.

OBJETIVO: O objetivo deste estudo foi examinar a confiabilidade e a validade convergente da Children Anxiety Sensitivity Index (CASI) com sintomas de transtornos de ansiedade de acordo com o DSM-IV, por meio da comparação com a Screen for Child Anxiety Related Emotional Disorders (SCARED). MÉTODOS: Crianças e adolescentes provenientes de cinco escolas foram selecionados de uma amostra de um estudo maior que avaliava diferentes aspectos dos transtornos de ansiedade. Todos os participantes completaram a CASI e a SCARED. RESULTADOS: Esse estudo demonstrou a confiabilidade do escore total da CASI. Meninas apresentaram escores de sensibilidade à ansiedade mais altos do que meninos e não houve diferença nos escores totais de sensibilidade de ansiedade entre crianças e adolescentes. Esse estudo encontrou correlações de moderada a alta entre os escores da CASI e os escores da SCARED, sendo todas as correlações positivas e significativas. CONCLUSÕES: Nossos achados demonstraram uma confiabilidade apropriada e evidência de validade convergente da CASI em uma amostra de crianças e adolescentes brasileiros.
