Abstract: The objective of this study was to compare the scores of the Helplessness, Magnification, Rumination, and Catastrophizing factors of the Pain Catastrophizing Scale (PCS) between samples with different pain characteristics. The psychometric properties of the PCS were evaluated in 1,151 Brazilian adults (78.9% female; 38.6 (SD = 10.8) years): 335 had no pain, 390 had been in pain for less than 3 months, 250 had been in recurring pain for more than 3 months, and 176 had been in continuous pain for more than 3 months. Confirmatory factor analysis (CFA) was conducted to verify the fit of the PCS models. Convergent validity and reliability were evaluated. Multi-group analysis was used to estimate the invariance of the factorial model. The global score for the PCS factors was obtained using the regression weight matrix for estimating factor scores from CFA. Analysis of variance was used to compare scores between samples. After excluding three items, the tri-factorial model showed adequate fit. The model parameters were invariant (Δχ2(λ,i,β,Res); p≥0.05). Individuals experiencing pain showed higher scores for catastrophic thoughts. Individuals with pain for less than 3 months had the highest scores for Rumination (p < 0.001). The PCS showed valid, reliable, and invariant results for the sample of Brazilian adults in no pain or with different pain conditions. The PCS adequately discriminated individuals in pain from those without pain. Among those in pain, Rumination was the only discriminating factor.

Resumo 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 países de língua portuguesa. Métodos: Um total de 4.020 indivíduos 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 extraída (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 excluídos 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.

Abstract Objective: 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. Methods: A total of 4,020 Brazilian, Portuguese, and Mozambican individuals participated in the study. The total sample was divided into four samples: Brazilian patients (n = 1,120), Brazilian students (n = 1,398), Portuguese students (n = 1,165) and Mozambican students (n = 337). Factorial validity of the WHOQOL-Bref was assessed by confirmatory factor analysis. The convergent and discriminant validities of the instrument were assessed using the average variance extracted (AVE) and the square of Pearson's correlational coefficient (r2), respectively. Composite reliability and ordinal alpha were used as measures of reliability. The metric, scalar, and strict invariance of WHOQOL-Bref was evaluated by multi-group analysis in independent subsamples (within each sample) and only between Brazil and Portugal (transnational invariance), because the configural model of Mozambique was different. Results: The original model of the WHOQOL-Bref did not show a good fit for the samples. Different items were excluded to fit the instrument in each sample (different models for WHOQOL-Bref among Brazilian, Portuguese, and Mozambican samples). AVE and r2 were not adequate; however, the reliability of the WHOQOL-Bref was good, except in the Mozambican sample. Invariance was observed only in independent subsamples. Conclusion: The WHOQOL-Bref fitted models showed adequate factorial validity and invariance in independent subsamples. The transnational non-invariance of the WHOQOL-Bref shows the influence of culture on the operationalization of the quality of life construct.

Verificar a influência do período de referência no relato da Intensidade e Interferência da dor na vida de indivíduos adultos. Participaram 832 indivíduos com dor nas últimas 24 horas. Como instrumentos de medida utilizou-se o Inventário Breve de dor (BPI), o Questionário de Auto eficácia em relação à Dor (PSEQ) e a Escala de Castastrofização da Dor (PCS). O BPI foi aplicado utilizando dois períodos de referência: última experiência dolorosa e últimas 24 horas. Os escores de Intensidade da dor, Interferência da dor nas atividades, Interferência da dor na afetividade e de Interferência da Dor foram comparados entre grupos com diferentes condições dolorosas (G1: dor há menos de 3 meses, G2: dor há mais de 3 meses recorrente, G3: dor há mais de 3 meses contínua). Os indivíduos foram reclassificados considerando os escores finais em GA-relato da última experiência dolorosa>dor nas últimas 24hs, GB-última experiência dolorosa<24hs e GC-última experiência dolorosa=24hs. Os escores médios de Intensidade e de Interferência da dor foram maiores para última experiência dolorosa para todos os grupos. Os indivíduos do G3 apresentaram maiores escores para última experiência dolorosa e interferência da dor nas atividades. Os indivíduos do GB apresentaram maiores escores de catastrofização e menores de auto eficácia. Verificou-se influência do período de referência nos escores de intensidade e interferência da dor na vida dos indivíduos.

To verify the influence of the reference period on the Intensity and Interference of pain in the life of adult individuals. 832 subjects with pain in the last 24 hours participated. The Brief Pain Inventory (BPI), the Self-Efficacy Questionnaire for Pain(PSEQ) and the Pain Catastrophization Scale (PCS) were used as measuring instruments. BPI was applied using two reference periods: last pain experience and last 24 hours. Pain Intensity, Pain Interference on daily activities, Pain Interference on affectivity were compared between groups with different pain conditions (G1: pain for less than 3 months, G2: recurrent pain for more than 3 months, G3: continuous pain for more than 3 months). The individuals were reclassified, considering the final scores from both BPI and PCS, into GA - report of the last painful experience> pain in the last 24hs, GB - last painful experience <24hs and GC - last painful experience = 24hs. Mean Intensity and Pain Interference scores were higher for last pain experience for all groups. G3 subjects presented higher scores for the last pain experience and pain interference in the activities. GB individuals had higher catastrophic scores and lower self-efficacy scores. There was an influence of the reference period on the pain intensity and interference scores in individuals' lives.

RESUMO JUSTIFICATIVA E OBJETIVOS: A utilização do questionário de autoeficácia relacionado à dor tem sido frequente, porém, limitada ao contexto da dor crônica. Os objetivos deste estudo foram: i) avaliar as propriedades psicométricas do questionário de autoeficácia relacionado à dor para amostra de indivíduos brasileiros com diferentes durações da ocorrência de dor, ii) apresentar uma nova proposta de estimativa do escore global da crença de autoeficácia e iii) comparar esse escore entre grupos com diferentes durações de dor. MÉTODOS: Participaram 1.155 adultos (79,0% mulheres; 38,6±10,8 anos). Do total, 337 não apresentavam dor, 386 relataram dor há menos de 3 meses, 253 relataram dor recorrente há mais de 3 meses e 179, dor contínua há mais de 3 meses. Realizou-se análise fatorial confirmatória para verificar o ajustamento do modelo do Questionário de Autoeficácia relacionado à Dor. A invariância do questionário de autoeficácia relacionado à dor foi testada utilizando análise multigrupos. Foi proposto cômputo do escore global da crença de autoeficácia a partir da matriz dos pesos de regressão da análise fatorial confirmatória. O escore de autoeficácia foi comparado entre grupos (ANOVA, alfa=5%). RESULTADOS: Após inserção de quatro correlações entre os erros dos itens, o modelo do questionário de autoeficácia relacionado à dor apresentou ajustamento adequado à amostra (X2/gl=7,059; CFI=0,978; GFI=0,964; RMSEA=0,072). O modelo foi invariante entre as amostras independentes. Menor escore de crença de autoeficácia foi encontrado entre os participantes com dor presente há menos de 3 meses (p<0,05). CONCLUSÃO: Há evidências da relação entre a crença de autoeficácia e as características da condição dolorosa, o que permite discussões acerca das conceituações teóricas envolvidas na percepção da dor e autoeficácia dos indivíduos.

ABSTRACT BACKGROUND AND OBJECTIVES: The pain self-efficacy questionnaire has been frequently used in several languages, but its use is limited to chronic pain. This study aimed to i) evaluate the properties of the pain self-efficacy questionnaire among Brazilians with different durations of pain occurrence; ii) present a new proposal for estimation of the overall self-efficacy belief score; and iii) compare such score among different pain duration time. METHODS: A total of 1,155 adults (79.0% women; 38.6±10.8 years) participated, 337 had no pain, 386 reported pain for less than 3 months, 253 reported pain for more than 3 months with a recurrent pattern, and 179 reported continuous pain for more than 3 months. The confirmatory factor analysis was performed to check the pain self-efficacy questionnaire unifactorial model good-fit. The pain self-efficacy questionnaire invariance was tested in independent samples using multigroup analysis. We proposed the calculation of the self-efficacy belief score from the factor score obtained in the confirmatory factor analysis. The score was compared among groups (ANOVA, alpha=5%). RESULTS: After inserting four correlations between errors of items, the pain self-efficacy questionnaire model shows to be fit to the sample (X2/df=7.059; CFI=0.978; GFI=0.964; RMSEA=0.072). The model was invariant between independent samples. Lower self-efficacy belief was found among participants with pain for less than three months (p<0.05). CONCLUSION: There is evidence of a relationship between the self-efficacy belief and the pain characteristics, where the presence of pain and length of time living with pain might be important factors in the study of the concepts involved in the perceptions of pain and self-efficacy.

Abstract: The objective of this study was to evaluate the psychometric properties of the Multidimensional Health Locus of Control – Form C (MHLC-C) scale applied to a sample of adult Brazilian patients with different pain conditions. The scores were then identified and compared on each of the subscales and profiles regarding locus of control. The sample consisted of 1,149 adult individuals (79% women; mean age: 36.6 years) of which 334 reported not feeling pain in the prior 24 hours, 386 reported pain in the prior three months, 250 reported recurring pain for the prior three months or longer, and 179 reported continuous pain for the prior three months or longer. A confirmatory factor analysis was performed. The invariance of the MHLC-C was tested on independent samples. The weighted global score was calculated for each of the factors and tested using ANOVA (α = 5%). Individuals were classified according to the eight health locus of control (HLC) profiles. The factors fit the data adequately after the model was refined. A higher score for the Health Professionals HLC was found among individuals reporting less than three months of pain. The “believer in control” profile was the most prevalent among the groups, while the least prevalent profile was the “pure chance” profile. The MHLC-C was found to be valid and reliable for assessing locus of control among people with different pain conditions. Only the Health Professionals HLC factor exhibited significantly different results for these individuals. The “believer in control” profile was the most prevalent among the pain conditions considered.

Depressão, Ansiedade e Estresse, consumo de medicamentos e prática de automedicação têm sido elevados em amostras normativas e clínicas. Assim, o objetivo deste estudo foi estimar o consumo de medicamentos, prática de automedicação e o nível de Depressão, Ansiedade e Estresse de pacientes odontológicos e sua relação com as variáveis demográficas. Participaram 209 indivíduos adultos (84,7% mulheres; idade 38,66 ±11,06 anos), atendidos na Faculdade de Odontologia de Araraquara. Utilizou-se a escala de Depressão, Ansiedade e Estresse (DASS-21). As propriedades psicométricas da DASS-21 foram avaliadas por análise fatorial confirmatória (c²/gl, CFI, TLI e RMSEA). Os escores finais de Depressão, Ansiedade e Estresse foram computados. A associação entre o consumo de medicamentos e automedicação segundo as variáveis demográficas foi verificada por meio do teste do qui-quadrado. Para comparação dos escores médios de Depressão, Ansiedade e Estresse segundo as variáveis de interesse foi realizada Análise de Variância (ANOVA). A DASS-21 foi válida e confiável (c²/gl=2,362-2,740; CFI=0,98-0,99; TLI=0,97-0,99; RMSEA=0,078-0,091; VEM=0,543-0,726; a=0,846-0,920; CC=0,892-0,948). Observou-se alta prevalência de consumo de medicamentos e automedicação. O maior consumo de medicamento foi entre indivíduos com idade entre 51-60 anos, com menor escolaridade e nível econômico C. A automedicação foi menor entre aqueles com idade entre 51-60 anos. Os escores de Depressão, Ansiedade e Estresse foram maiores entre os que consumiram medicamentos (antidepressivos, ansiolíticos, analgésicos e relaxantes musculares) com frequência. O consumo de medicamento e a automedicação estiveram associados com características demográficas e os maiores escores da DASS-21 foram encontrados entre aqueles consumiram algum tipo medicamento recentemente.

Depression, Anxiety and Stress levels has been high in normative and clinical population samples as well as the consumption of medicines and self-medication. The aim of this study was to estimate the consumption of medicine, practice of self-medication and the level of Depression, Anxiety and Stress among dental patients and its relationship with demographic variables. The individuals (n=209 adults; 84.7% women; age: 38.66 ±11.06 years) who sought dental care at Araraquara Dentistry School participated in the study. The Depression, Anxiety and Stress Scale (DASS-21) was used. The psychometric properties of the DASS-21 by confirmatory factor analysis (c²/df, CFI, TLI and RMSEA). The scores of Depression, Anxiety and Stress were computed. The association between consumption of medicine and self-medication according to demographic variables was performed using the chi-square test. To compare the mean scores of Depression, Anxiety and Stress according to variables of interest was performed analysis of variance (ANOVA). The DASS-21 presented adequate validity and reliability (c²/df=2.362-2.740; CFI=0.98-0.99; TLI=0.97-0.99; RMSEA=0.078-0.091; AVE=0.543-0.726; a=0.846-0.922; CR=0.892-0.948). There was a high prevalence of consumption of medicines and self-medication. Individuals aged 51-60 years, with low educational and economic level C consumed more medicine. The practice of self-medication was lower among those aged 51-60 years. The Depression, Anxiety and Stress were higher among those who consumed antidepressants, anxiolytics, analgesics and muscle relaxants more often. It was concluded that the consumption of medicine and practice of self-medication were associated with demographic characteristics and major DASS-21 scores were found among individuals who consumed of medicine recently.

RESUMO: Objetivo: Estimar a associação entre o padrão de beber com risco e as variáveis sociodemográficas, e comparar os escores médios dos fatores relacionados com a Síndrome de Burnout , de acordo com o padrão do consumo de álcool em funcionários de duas prisões brasileiras. Métodos: Trata-se de um estudo transversal, desenvolvido com 339 participantes (taxa de resposta de 63,8%). Os instrumentos utilizados foram um questionário sociodemográfico, o Teste para Identificação de Problemas Relacionados ao Uso de Álcool (AUDIT) e o Inventário de Burnout de Maslach - Forma Geral (MBI-GS). Resultados: A média de idade dos participantes foi de 40,2 (DP = 8,8) anos, e 81,1% eram do sexo masculino. Um total de 78,5% dos participantes (IC95% 74,1 - 82,8) relatou consumir bebidas alcoólicas. A prevalência do comportamento de beber com risco na amostra foi de 22,4% (IC95% 18,0 - 26,9) e a da Síndrome de Burnout foi de 14,6% (IC95% 10,8 - 18,4). Observou-se associação significativa entre o comportamento de beber com risco com o gênero, o maior risco para os homens (OR = 7,32, p < 0,001), o tabagismo, risco aumentado para os fumantes (OR = 2,77, p < 0,001) e a prática religiosa, mostrando menor risco para os praticantes de religião (OR = 0,364, p < 0,001). Notaram-se escores médios (p < 0,001) mais altos de exaustão emocional e cinismo, e menor pontuação de eficácia profissional entre os indivíduos que relataram consumir bebidas alcoólicas. Conclusão: Homens fumantes foram os mais propensos a desenvolverem um padrão de beber com risco, enquanto a religião é apresentada como um fator protetor. Os indivíduos que consomem álcool foram os mais afetados pelos diferentes fatores da Síndrome de Burnout .

ABSTRACT: Objective: The aims of this study were to estimate the association between an at-risk drinking pattern and sociodemographic variables, and to compare the mean scores of the factors associated with the Burnout Syndrome, according to the alcohol consumption pattern in staff members from two Brazilian prisons. Methods: A cross-sectional study was developed with 339 participants (response rate = 63.8%). The instruments used were a sociodemographic questionnaire, the Alcohol Use Disorders Identification Test (AUDIT), and the Maslach Burnout Inventory - General Survey (MBI-GS). Results: The participants' average age was 40.2 (SD = 8.8) years, and 81.0% were male. Among 78.5% of participants (95%CI 74.1 - 82.8) reported consuming alcoholic beverages. The prevalence of at-risk drinking behavior in the sample was 22.4% (95%CI 18.0 - 26.9), and of the Burnout Syndrome was 14.6% (95%CI 10.8 - 18.4). We observed a significant association between at-risk drinking behavior with gender, higher risk for men (OR = 7.32, p < 0.001), smoking, increased risk for smokers (OR = 2.77, p < 0.001), and religious practice, showing lower risks for religion practitioners (OR = 0.364, p < 0.001). We noticed significantly higher mean scores (p < 0.001) of emotional exhaustion and cynicism, and lower scores of professional achievement among individuals who reported consuming alcoholic beverages. Conclusion: Men who smoke were more likely to develop an at-risk drinking pattern, while religion is presented as a protective factor. Individuals who consume alcohol were more affected by the different factors of the Burnout Syndrome.

Abstract: The aim of this study was to evaluate the properties of the Dental Anxiety Scale (DAS) when applied to Brazilian adults and to test its invariance across independent samples and different sociodemographic groups. Sociodemographic data, reports on previous unpleasant dental experiences and DAS responses were collected through telephone interviews. Metric properties of the one and two-factor models were evaluated using confirmatory factor analysis. The analysis included the chi-square ratio divided by degrees of freedom (χ2/df), the comparative fit index (CFI), the goodness of fit index (GFI) and the root mean square error of approximation (RMSEA). Convergent validity was evaluated using the average variance extracted (AVE). Cronbach's alpha (α) and composite reliability (CR) were calculated. In the two-factor model, discriminant validity was evaluated. The invariance of the models was evaluated using a multigroup analysis of the independent samples (pΔχ2λ, pΔχ2 i and pΔχ2 Res ≥ 0.05). Telephone interviews were held with 350 individuals (74.3% women). Of the participants, 135 (38.6%) had previous unpleasant dental experiences, and 117 (33.4%) knew someone who had had this type of experience. The one- and two-factor model (χ2/df < 2.0; CFI,GFI > 0.90; RMSEA < 0.10; AVE > 0.50; α,CR > 0.70) were adjusted to the data. Discriminant validity was limited (ρ2 = 0.66). Both models presented strong invariance across independent samples, but the invariance was weak (pΔχ2i < 0.05) when samples were defined by socioeconomic variables. In conclusion, both DAS models were valid and reliable when applied to a sample of Brazilian adults. However, the weak invariance of the models suggests that sample characteristics interfered with the measurement of dental anxiety.

The aim of this study was to assess the validity and reliability of the Fonseca Anamnestic Index (IAF), used to assess the severity of temporomandibular disorders, applied to Brazilian women. We used a probabilistic sampling design. The participants were 700 women over 18 years of age, living in the city of Araraquara (SP). The IAF questionnaire was applied by telephone interviews. We conducted Confirmatory Factor Analysis (CFA) using Chi-Square Over Degrees of Freedom (χ2/df), Comparative Fit Index (CFI), Tucker-Lewis Index (TLI), and Root Mean Square Error of Approximation (RMSEA) as goodness of fit indices. We calculated the convergent validity, the average variance extracted (AVE) and the composite reliability (CR). Internal consistency was assessed by Cronbach's alpha coefficient (α).The factorial weights of questions 8 and 10 were below the adequate values. Thus, we refined the original model and these questions were excluded. The resulting factorial model showed appropriate goodness of fit to the sample (χ2/df = 3.319, CFI = 0.978, TLI = 0.967, RMSEA = 0.058). The convergent validity (AVE = 0.513, CR = 0.878) and internal consistency (α = 0.745) were adequate. The reduced IAF version showed adequate validity and reliability in a sample of Brazilian women.

OBJETIVO: Este estudo teve por objetivo estimar a efetividade de diferentes métodos de rastreamento da Síndrome de Burnout em estudantes de Odontologia. MATERIAL E MÉTODO: Utilizou-se o Inventário de Oldenburg (OLBI‑SS) e o Inventário de Copenhagen (CBI-SS). Como padrão-ouro utilizou-se o Inventário de Burnout de Maslach (MBI-SS). As qualidades psicométricas dos instrumentos foram estimadas. O modelo hierárquico de segunda ordem foi estimado para cálculo do escore global do OLBI-SS e do CBI-SS. As curvas ROC foram construídas e as áreas estimadas (AUROC). RESULTADO: Participaram 235 estudantes de um curso de graduação. Os instrumentos apresentaram adequada confiabilidade e validade e para tanto, foi necessário remover três questões do OLBI-SS e uma do CBI-SS. CONCLUSÃO: Observou-se boa capacidade discriminante das dimensões Exaustão do OLBI-SS e BP e BRE do CBI-SS. O CBI-SS apresentou capacidade discriminante superior à do OLBI-SS na identificação da Síndrome de Burnout (DAUROC=.172 [.103-.240]; p<.05).

OBJECTIVE: This study was proposed to estimate the effectiveness of different screening methods of the Burnout Syndrome among dental students. MATERIAL AND METHOD: The Burnout Syndrome assessment was performed using the Oldenburg Inventory-Student survey (OLBI-SS) and the Copenhagen Inventory-Student survey (CBI‑SS). The Maslach Burnout Inventory-Student survey (MBI-SS) was used as the gold standard. The psychometric properties of the instruments were measured. The second-order hierarchical model was estimated to calculate the overall scores for OLBI-SS and CBI-SS, and ROC curves were constructed and the areas were estimated (AUROC). RESULT: A total of 235 undergraduate students participated in this study. The instruments showed an adequate reliability and validity; however three questions had to be removed from OLBI-SS and one from CBI-SS. The Exhaustion dimension of OLBI-SS, and Personal Burnout and Study related Burnout of CBI-SS presented a good discriminating capacity. CONCLUSION: CBI-SS showed higher discriminating capacity, than OLBI-SS, to identify the Burnout Syndrome (DAUROC=.172 [.103-.240]; p<.05).

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.

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.

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.

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.
