Aim: To estimate the reliability and validity of the Dental Anxiety Scale (DAS) and identify the prevalence and the effect of the socio-demographic characteristics of dental anxiety, in a sample of 212 adults. Methods: The psychometric sensitivity of the scale was assessed. A confirmatory factor analysis was performed, and the convergent validity and internal consistency were determined. The prevalence of anxiety was estimated, and the effect of socio-demographic variables on anxiety was assessed using structural equation modelling. Results: The participants’ mean age was 33.5 (SD = 15.6) years, and 62.3% were female. There was an adequate factorial adjustment of the scale in this sample. The convergent validity and internal consistency were adequate in the one-factor model. Regarding two-factor model, there was a high correlation (r) among the factors, which jeopardized the discriminant validity. A total of 47.6% of the participants (IC95% = 40.9 - 54.4) presented low levels of anxiety, 32.5% (IC95% = 26.2 - 38.9) moderate levels, and 12.3% (IC95% = 7.8 - 16.7) exacerbated levels. There was a non-significant effect of gender, age and education on the anxiety levels of this sample. Conclusion: We concluded that the one-factor model presented better psychometric qualities, that anxiety was highly prevalent and there was no significant effect of the demographic variables on anxiety, in this sample.

Há associação significativa entre Burnout e gênero (p = 0,020) e instalações de trabalho (p = 0,011), sendo mais acometidos os homens e aqueles que consideram as instalações de trabalho ruins. ------ ABSTRACT ------- Objective: the objective of this study was to estimate the prevalence of Burnout Syndrome in dentists in the public service in the city of Araraquara – SP and its association with the variables of interest. Material and method: The sample was made up of the dentists active in the public health network (n = 60). Socio-demographic data was collected. The Oldenburg Burnout Inventory (OLBI) was used. Result: Of the participants, 60.0% were female and the average age was 41.9 ± 7.6 years. A large number of the professionals displayed a normal perception of the work conditions, premises, materials and equipment. 63.3% of the individuals feel tired even before arriving for work, 58.3% need more time to relax and to feel better, 70.0% are unable to deal well with the pressures of work, 50.0% feel they have no energy during or after work and 86.7% do not consider the work to be a positive challenge. It was observed that 48.3% of dentists displayed Burnout Syndrome, 11.7% Detachment and 13.3% Exhaustion. There was a significant association between the presence of Burnout and gender (p = 0.020) and the work premises (p = 0.011), with men being the most affected and those that considered the work premises very poor. Conclusion: It was concluded that the prevalence of Burnout Syndrome among dentists is high, with men and those who consider the work premises bad being the most affected.

Introduction: The COVID-19 pandemic brought profound societal changes and disruptions, including in the education system, which underwent swift modifications. It presented unique challenges for both professors and students, contributing to an increase in the prevalence of mental health-related symptoms. Objective: To determine the prevalence of mental health disorders symptoms, coping strategies, and concerns among students (≥18 years) and professors at different times during the COVID-19 pandemic. Methods: This was an online cross-sectional study (Student: N = 6,609; Phase 1 = 3,325; Phase 2 = 1,402; Phase 3 = 1,882; Professor: N = 9,096; Phase 1 = 3,924; Phase 2 = 2,223; Phase 3 = 2,949). Depression, Anxiety, and Stress Scale (DASS-21), Impact of Event Scale-revised (IES-R), and BriefCOPE inventory were used. The probability of presenting the symptoms was calculated by multiple logistic regression and odds ratio (OR). Results: The prevalence of depression, anxiety, stress, and distress symptoms among students and professors was high (≥59.5% and ≥ 33.5%, respectively). Students, women, and those diagnosed with a mental disorder were more likely to have symptoms or distress. In the face of the pandemic, professors used more adaptive coping strategies than students. Health was the focus of professors’ concerns, while for students, future and labor market uncertainty were concerns derived from the health core. Conclusion: The results point to the need to strengthen psychosocial support for both professors and students.

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.

The burnout syndrome is characterized by professional exhaustion and has been reported in college students. The aim of this study was to estimate the prevalence of Burnout Syndrome among dentistry students from a public university, and its relationship to socio-demographic characteristics. All students (n = 300) were invited to participate. We used the Maslach Burnout Inventory - Student Version (MBI-SS). We carried out an analysis of the MBI-SS’ psychometric properties. Multivariate Analysis of Variance (MANOVA) was performed, followed by Analysis of Variance (ANOVA) and Tukey’s post-hoc tests to compare the mean scores of burnout dimensions. Of the 235 participants, 72.8% were women and the mean age was 21.0 ± 1.8 years. The MBI-SS was reliable and valid. Of the students, 17.0% had Burnout Syndrome. There was a significant relation between Burnout Syndrome and a student’s performance during the course (F = 4.433, p < 0.001), medication intake because of studies (F = 7.721, p < 0.001), and the thought of dropping the course (F = 16.168, p < 0.001). The students most affected were those with poor performance, those who took medication because of studies, and those with thoughts of dropping the course. We concluded that the prevalence of the syndrome among dentistry students was high, with a significant relation between the syndrome and a student’s academic performance, use of medication because of studies, and thoughts of dropping the course. ------ RESUMO ------ A Síndrome de Burnout caracteriza-se por esgotamento profissional e tem sido relatada em estudantes universitários. O objetivo desse estudo foi estimar a prevalência da Síndrome de Burnout em estudantes de Odontologia de uma universidade pública e sua relação com características sociodemográficas. Todos os estudantes (n = 300) foram convidados a participar. Utilizou-se o Inventário de Burnout de Maslach – versão estudantes (MBI-SS). Realizou-se análise das propriedades psicométricas do MBI-SS. Para comparação entre os escores médios das dimensões do Burnout realizou-se Análise de Variância Multivariada (MANOVA) seguida de Análise de Variância (ANOVA) e testes post-hoc de Tukey. Dos 235 participantes, 72,8% eram mulheres e a média de idade era de 21,0 ± 1,8 anos. O MBI-SS mostrou-se confiável e válido. Dos estudantes, 17,0% apresentaram a Síndrome de Burnout. Verificou-se relação significativa entre a Síndrome de Burnout e o desempenho do estudante no curso (F = 4,433, p < 0,001), o consumo de medicação devido aos estudos (F = 7,721, p < 0,001) e o pensamento de desistir do curso (F = 16,168, p < 0,001). Foram mais acometidos aqueles com desempenho ruim no curso, que consomem medicações devido aos estudos e que já pensaram em desistir do curso. Conclui-se que a prevalência da Síndrome entre os estudantes de Odontologia foi alta, sendo significativa a relação entre a Síndrome e o desempenho do estudante no curso, o consumo de medicação devido aos estudos e o pensamento de desistir do curso.

OBJETIVO: Realizar a adaptação transcultural da versão em português do Inventário de Burnout de Maslach para estudantes e investigar sua confi abilidade, validade e invariância transcultural. MÉTODOS:A validação de face envolveu participação de equipe multidisciplinar. Foi realizada validação de conteúdo. A versão em português foi preenchida em 2009, pela internet, por 958 estudantes universitários brasileiros e 556 portugueses da zona urbana. Realizou-se análise fatorial confi rmatória utilizando-se como índices de ajustamento o 2/df, o comparative fi t index (CFI), goodness of fi t index (GFI) e o root mean square error of approximation (RMSEA). Para verifi cação da estabilidade da solução fatorial conforme a versão original em inglês, realizou-se validação cruzada em 2/3 da amostra total e replicada no 1/3 restante. A validade convergente foi estimada pela variância extraída média e confi abilidade composta. Avaliou-se a validade discriminante e a consistência interna foi estimada pelo coefi ciente alfa de Cronbach. A validade concorrente foi estimada por análise correlacional da versão em português e dos escores médios do Inventário de Burnout de Copenhague; a divergente foi comparada à Escala de Depressão de Beck. Foi avaliada a invariância do modelo entre a amostra brasileira e a portuguesa. RESULTADOS: O modelo trifatorial de Exaustão, Descrença e Eficácia apresentou ajustamento adequado (2/df = 8,498; CFI = 0,916; GFI = 0,902; RMSEA = 0,086). A estrutura fatorial foi estável (: 2 dif = 11,383, p = 0,50; Cov: 2 dif = 6,479, p = 0,372; Resíduos: 2 dif = 21,514, p = 0,121). Observou-se adequada validade convergente (VEM = 0,45;0,64, CC = 0,82;0,88), discriminante (2 = 0,06;0,33) e consistência interna ( = 0,83;0,88). A validade concorrente da versão em português com o Inventário de Copenhague foi adequada (r = 0,21;0,74). A avaliação da validade divergente do instrumento foi prejudicada pela aproximação do conceito teórico das dimensões Exaustão e Descrença da versão em português com a Escala de Beck. Não se observou invariância do instrumento entre as amostras brasileiras e portuguesas (:2 dif = 84,768, p < 0,001; Cov: 2 dif = 129,206, p < 0,001; Resíduos: 2 dif = 518,760, p < 0,001). CONCLUSÕES: A versão em português do Inventário de Burnout de Maslach para estudantes apresentou adequada confi abilidade e validade, mas sua estrutura fatorial não foi invariante entre os países, apontando ausência de estabilidade transcultural.

Objective: This cross-sectional study sought to conduct a spatially analysis of the distribution of dental caries and the nutritional status (NS) of 5-year-old preschool children of public schools in the city of Araraquara, São Paulo, Brazil. Methods: The sample was selected in a stratified probabilistic manner. A dental examination was conducted to investigate the dmft index. The anthropometric indicators of the weight/ height (W/H), height/age (H/A), weight/age (W/ A) and body mass index (BMI) were calculated to estimate the NS. A descriptive statistical analysis was conducted and a thematic map was created. At the end of the study 491 children had full address codification. A GPS device was used to ascertain the geographic reference points. A pluridirectional semi-variogram was elaborated. Results: It was revealed that both variables presented a pure nugget effect showing the absence of a spatial correlation, in other words the dmft and nutritional status are not regionalized variables, and their values do not reveal direct spatial dependence. Conclusions: Dental caries and nutritional status are health conditions that do not reveal spatial dependence. Ultimately, the combination of these indicators with others can produce spatial dependence effects.

Objetivo: comparar o consumo energético, de macronutrientes e fibras por mulheres portadoras de dor miofascial crônica e não portadoras, atendidas durante o ano de 2006, em uma Clínica de Fisioterapia da cidade de Araraquara - SP. Métodos: Os grupos – controle e dor miofascial – foram definidos pelo Critério de Diagnóstico na Pesquisa para Desordens Temporomandibulares - Eixos I e II, sendo compostos por 36 e 37 indivíduos, respectivamente. As participantes foram entrevistadas para o preenchimento do recordatório alimentar de 24 horas de dois dias. A análise da ingestão de energia, macronutrientes e fibras foi realizada com auxílio do programa Virtual Nutri e os grupos foram comparados pelo teste t Student. Para o grupo com dor miofascial, foi realizado estudo de Correlação de Pearson entre os domínios propostos pelo Critério de Diagnóstico na Pesquisa para Desordens Temporomandibulares – intensidade média da dor, depressão, sintomas inespecíficos incluindo itens de dor e limitação da função mandibular – e o consumo de energia, macronutrientes e fibras. O nível de significância adotado foi de 5%. Resultados: Houve diferença estatisticamente significante entre os grupos no consumo de proteínas e lipídios, sendo este menor no grupo de mulheres portadoras de dor miofascial crônica. O consumo energético e de fibras esteve no limite de significância. Observou-se correlação não significativa entre os domínios do Critério de Diagnóstico na Pesquisa para Desordens Temporomandibulares e o consumo de energia, macronutrientes e fibras. Conclusão: O consumo de proteínas e lipídios foi diferente entre portadores e não portadores de dor miofascial crônica.

The aim of this study was to estimate the reliability, validity and factorial invariance of the Portuguese version of the Geriatric/ General Oral Health Assessment Index (GOHAI) as applied to Brazilian women. A total 701 women over 18 years of age participated in this study. Telephone interviews were conducted. We evaluated the construct-related validity through factorial, convergent and discriminant validity. We carried out a confirmatory factor analysis using the χ2/df, CFI, GFI and RMSEA indexes. The invariance of the model in a second independent sample was estimated by multi-group analysis and internal consistency using Cronbach’s alpha coefficient. Items 5 and 9 presented factor weights below the adequate value and were removed. The three-dimensional and unifactorial model presented an adequate fit. We observed strong factorial invariance of the models in two independent samples (three-factor: ρλ = 0.62; pCov = 0.89, one-factor: ρλ = 0.81; pCov = 0.68) and weak factorial invariance between users and nonusers of dental prosthetics (threefactor: ρλ = 0.55; pCov = 0.01, one-factor: ρλ = 0.51; pCov = 0.02). The convergent validity was suboptimal. Internal consistency was adequate. The GOHAI applied to the study sample showed adequate reliability, factorial validity and stability in independent samples and between users and nonusers of dental prosthetics in both the threedimensional and the unifactorial structures.
