Ansiedade social: adaptação e evidências de validade da forma curta da Social Interaction Anxiety Scale e da Social Phobia Scale para o Brasil / Social anxiety: adaptation and evidence of validity of the short form of the Social Interaction Anxiety Scale and Social Phobia Scale for Brazil

OBJETIVO: A ansiedade social é um transtorno psicológico pouco publicizado, mas com importante distribuição epidemiológica. O presente estudo teve como objetivo adaptar para o contexto brasileiro as versões reduzidas da Social Interaction Anxiety Scale (SIAS) e da Social Phobia Scale (SPS) (SIAS-6 e SPS-6) e produzir evidências de validade. Essas escalas avaliam ansiedade em interações sociais e ansiedade social diante da possibilidade de escrutínio por outras pessoas, sendo complementares. MÉTODOS: Como são escalas com reconhecido uso internacional, a adaptação para o Brasil pode trazer contribuições para as investigações clínicas e científicas acerca do transtorno de ansiedade social. Foram realizados processos criteriosos para a adaptação (tradução, avaliação por juízes, retrotradução, avaliação pelo público-alvo) e conduzido um levantamento on-line com 1.049 pessoas, maiores de 18 anos, com média de idade de 25,98 anos (DP = 7,55). RESULTADOS: Utilizaram-se Análises Fatoriais Confirmatórias e, desse modo, constatou-se que os índices de ajuste produzidos são, em geral, adequados (SRMR < 0,04, CFI > 0,96, TLI > 0,94 e RMSEA < 0,05) e que os itens possuem cargas fatoriais adequadas (entre 0,441 e 0,837). As evidências de validade discriminante também se mostraram satisfatórias, conseguindo diferenciar grupos por renda e orientação sexual, como esperado pela literatura. CONCLUSÕES: Os resultados sugerem que as escalas são adequadas para uso no Brasil, tanto para uso em separado como para uso combinado, como fatores correlacionados.

OBJECTIVE: Social anxiety is a poorly publicized psychological disorder, but with an important epidemiological distribution. The present study aimed to adapt the reduced versions of the Social Interaction Anxiety Scale (SIAS) and Social Phobia Scale (SPS) (SIAS-6 and SPS-6) to the Brazilian context and produce evidence of validity. These scales assess anxiety in social interactions and social anxiety in face of the possibility of scrutiny by other people, being complementary. METHODS: As they are scales with recognized international use, adaptation to Brazil can bring contributions to clinical and scientific investigations about Social Anxiety Disorder. Judicious processes for adaptation were carried out (translation, evaluation by judges, back-translation, evaluation by the target audience) and an online survey was conducted with 1,049 people, over 18 years of age with an average age of 25.98 years (SD = 7.55). RESULTS: Confirmatory Factor Analysis was used and, thus, it was found that the adjustment indexes produced are, generally, adequate (SRMR < 0.04, CFI > 0.96, TLI > 0.94 and RMSEA < 0.05) and that the items have adequate factor loads. Evidence of discriminant validity was also satisfactory, managing to differentiate groups by income and sexual orientation as expected by the literature. CONCLUSIONS: The results suggest that the scales are suitable for use in Brazil, both for separate use and for combined use, as correlated factors.

Psychometric properties of the Brazilian Intolerance of Uncertainty Scale - Short Version (IUS-12)

Abstract Introduction The Intolerance of Uncertainty Scale - Short Version (IUS-12) is a measure of trait intolerance of uncertainty. Objective The purpose of the present study was to conduct a cross-cultural adaptation of the IUS-12 for use in Brazil and to investigate the scale's psychometric properties. Methods The research was conducted via an online research platform with a sample (n = 704; 80.1% female and 19.9% male) from different states in all five regions of Brazil. Participants were adults between 18 and 59 years of age (mean = 26.74; standard deviation = 8.36) who completed the Brazilian version of the IUS-12 online along with other anxiety-related measures. Results Confirmatory factor analysis demonstrated that the original two-dimensional structure fit the sample well. The total score for the scale had good internal consistency (Cronbach's alpha [α] = 0.88), as did both subscales (i.e. Prospective IU α = 0.79; Inhibitory IU α = 0.86). Conclusions The results demonstrated strong positive correlations with measures of anxiety-related constructs, contributing to the transdiagnostic understanding of IU. The IUS-12 appears to be a useful tool for assessment of IU and its availability has several implications of theoretical importance and practical utility for understanding of psychopathology and uncertainty.

Psychometric properties of the Liebowitz Social Anxiety Scale in a large cross-cultural Spanish and Portuguese speaking sample

Objective: To examine the psychometric properties of the Liebowitz Social Anxiety Scale-Self Report (LSAS-SR) based on a large sample recruited from 16 Latin American countries, Spain, and Portugal. Methods: Two groups of participants were included: a non-clinical sample involving 31,243 community subjects and a clinical sample comprising 529 patients with a diagnosis of social anxiety disorder (SAD). Exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM) were used in order to determine the psychometric properties of the LSAS-SR. Results: EFA identified five factors with eigenvalues greater than 1.00 explaining 50.78% of the cumulative variance. CFA and ESEM supported this 5-factor structure of the LSAS-SR. The factors included: 1) speaking in public; 2) eating/drinking in front of other people; 3) assertive behaviors; 4) working/writing while being observed; and 5) interactions with strangers. Other psychometric properties such as inter-factor correlations, invariance, reliability, and validity of the scale were also found. Conclusion: Psychometric data support the internal consistency and convergent validity of the LSAS-SR. It seems to be a valid and reliable measure of global social anxiety for Spanish and Portuguese-speaking countries, although when considering a multidimensional approach (factor-based assessment) it seems to be lacking some relevant social situations that are feared in those countries.

Screening of social phobia symptoms in a sample of Egyptian university students

Abstract Background Public speaking is a main requisite for academic achievement amongst university students. Epidemiological data on social phobia among University students in the Arab World are scarce. Objectives To screen for social phobia symptoms in a representative sample of Egyptian university students, and to highlight some putative risk factors associated with them. Methods Two thousand nine hundred and nineteen Egyptian university students participated in the study. They were screened for social phobia using Brief Social Phobia Scale (BSPS). Students total and subdomain scores on the BSPS were correlated with their demographic and scholastic variables. Results Social phobia symptoms were estimated to be prevalent among (44%) of the study sample. A significant (p < 0.05) negative correlation was found between students' age and avoidance scores on BSPS and between students' educational year and their scores on fear, avoidance and physiologic subdomains on the BSPS. Regression analysis pointed out to a number of predictive factors for the higher total BSPS scores such as female gender and being a medical student. Discussion Our study demonstrated a high rate of social phobia symptoms in university students. It also demonstrated a number of significant predictive factors associated with the domains of social phobia such as gender, BMI, scholastic year and faculty type.
