- Aspetos da vida universitária e a síndrome de burnoutPublication . Jordani, Paula Cristina; Zucoloto, Miriane Lucindo; Bonafé, Fernanda Salloumé Sampaio; Maroco, João; Campos, Juliana Alvares Duarte BoniniObjetivo: Estimar a prevalência da Síndrome de Burnout em estudantes de Odontologia de uma universidade pública e comparar os scores médios obtidos em cada dimensão do Inventário de Burnout de Oldenburg (OLBI-S) segundo as variáveis sociodemográficas de interesse. Participaram 235 estudantes. Métodos: As características psicométricas do OLBI-S foram estimadas. A comparação dos scores médios de Exaustão e Distanciamento foi realizada pelo teste t de Student e Análise de Variância (ANOVA). Resultados: Dos participantes 72,8% eram mulheres e a média de idade foi de 21,0±1,8 anos. Após a remoção de três itens, o OLBI-S apresentou adequada validade fatorial e confiabilidade. Dos estudantes, 61,7% apresentaram a Síndrome de Burnout, 22,1% Exaustão e 4,7% Distanciamento. Observou-se maior score médio de Distanciamento nos estudantes que não escolheram o curso de Odontologia como primeira opção e que consideraram os professores incompetentes/razoáveis. Aqueles cujas expectativas iniciais foram frustradas, com desempenho ruim no curso, que já consumiram medicação devido aos estudos e que já pensaram em desistir do curso apresentaram maiores scores médios tanto de Exaustão quanto de Distanciamento. Conclusão: A prevalência da Síndrome de Burnout é alta com relação significativa com variáveis sociodemográficas. ------ ABSTRACT ------ Aim: To estimate the prevalence of Burnout Syndrome in dental students, from a public university, and compare the mean scores obtained in each dimension of the Oldenburg Burnout Inventory (OLBI-S), according to the sociodemographic variables of interest. A total of 235 students participated in the study. Methods: The psychometric characteristics of OLBI-S were estimated. The comparison of Exhaustion and Disengagement mean scores was performed, using the Student’s t test and Analysis of Variance (ANOVA). Results: A total of 72.8% of the participants were women and the mean age was 21.0 ± 1.8 years. After the removal of three items, OLBI showed adequate factorial validity and reliability. Of the surveyed students, 61.7% had Burnout Syndrome, 22.1% Exhaustion and 4.7% Disengagement. A higher Disengagement mean score was observed for students who did not chose the Dentistry course as their first choice, and who consider teachers to be incompetent/reasonable. Those whose initial expectations were frustrated, with poor course performance, who already used medication due to their study load, and who thought about quitting the course, had higher mean scores of both Exhaustion and Disengagement. Conclusion: There is a high prevalence of Burnout Syndrome, with a significant relation to sociodemographic variables.
- General oral health assessment index: A new evaluation proposalPublication . Campos, Juliana Alvares Duarte Bonini; Zucoloto, Miriane Lucindo; Bonafé, Fernanda Salloumé Sampaio; Maroco, JoãoObjectives: To validity the General Oral Health Assessment Index (GOHAI) among adults who sought dental care and to present a new proposal for calculating scores on self-perception of oral health. Background: There is no study that presents a GOHAI scores using weight of the items. Materials and Methods: The one-factor model, the three-factor model (physical function, psychosocial/psychological function and pain/discomfort) and the second-order hierarchical model (SOHM) were evaluated from confirmatory factor analysis (λ, χ2/df, CFI,GFI and RMSEA). The reliability (CR,α) was estimated. Concurrent validity was assessed using the Oral Health Impact Profile (OHIP-14). The invariance of the models was estimated in independent samples. The calculation of an overall score using the factor scores was proposed to obtain the overall weighted scores. These overall weighted scores were compared to the scores estimated as the simple arithmetic mean (overall unweighted scores) using a repeated measures analysis of variance. Results: A total of 1000 individuals participated (74.1% female; age: 40.7 (SD=14.3) years). Three items of the GOHAI were excluded (λ<0.40). The one-factor model (λ=0.40-0.77; χ2/df=6.291; CFI=0.947; GFI=0.960; RMSEA=0.073) and the three-factor model (λ=0.40-0.78; χ2/df=8.321; CFI=0.932; GFI=0.954; RMSEA=0.086) each presented an adequate fit. Reliability was adequate (one-factor: CR=0.83/ α=0.83; three-factor: CR=0.53-0.76/ α=0.53-0.73), with the exception of the pain/discomfort factor. The GOHAI was invariant in independent samples, and the concurrent validity was adequate. The overall unweighted scores overestimated self-perceptions of oral health when compared with the weighted scores. Conclusion: Both the one-factor and three-factor models of the GOHAI were found to be valid, reliable and invariant for the sample after the exclusion of three items. The use of overall weighted scores is recommended for calculating the score of self-perception of oral health.
- Impact of oral health on health-related quality of life : A cross-sectional studyPublication . Zucoloto, Miriane Lucindo; Maroco, João; Campos, Juliana Alvares Duarte BoniniBackground: Despite the consensus regarding the existence of a relationship between “impacts on oral health” and “health-related quality of life”, this relationship, considering the latent nature of these variables, is still poorly investigated. Thus, we performed this study in order to determine the magnitude of the impacts of oral health, demographic and symptom/clinical variables on the health-related quality of life in a Brazilian sample of dental patients. Methods: A total of 1,007 adult subjects enrolled in the School of Dentistry of São Paulo State University (UNESP) - Araraquara Campus for dentistry care between September/2012 and April/2013, participated. 72.4 % were female. The mean age was 45.7 (SD = 12.5) years. The Oral Health Impact Profile (OHIP-14) and the Short Form Health Survey (SF-36) were used. The demographic and symptom/clinical variables collected were gender, age, economic status, presence of pain and chronic disease. The impact of studied variables on health-related quality of life were evaluated with a structural equation model, considering the factor “Health” as the central construct. The fit of the model was first analyzed by the evaluation of the goodness of fit indices (χ 2 /df ≤ 2.0, CFI and TLI ≥ 0.90 and RMSEA < 0.10) and the evaluation of the variables’ impact over health-related quality of life was based on the statistical significance of causal paths (β), evaluated by z tests, for a significance level of 5 %. Results: We observed adequate fit of the model to the data (χ 2 /df = 3.55; CFI = 0.95; TLI = 0.94; RMSEA = 0.05). The impacts on oral health explained 28.0 % of the variability of the health-related quality of life construct, while the total variance explained of the model was 39.0 %. For the demographic and symptom/clinical variables, only age, presence of pain and chronic disease showed significant impacts (p < 0.05). Conclusion: The oral health, age, presence of pain and chronic disease of individuals had significant influence on health-related quality of life.
- Psychometric properties of the oral health impact profile and new methodological approachPublication . Zucoloto, Miriane Lucindo; Maroco, João; Campos, Juliana Alvares Duarte BoniniObjective: Evaluate the validity, reliability, and factorial invariance of the complete Portuguese version of the Oral Health Impact Profile (OHIP) and its short version (OHIP-14). Methods: A total of 1,162 adults enrolled in the Faculty of Dentistry of Araraquara/UNESP participated in the study; 73.1% were women; and the mean age was 40.7 ± 16.3 yr. We conducted a confirmatory factor analysis, where χ2/df, comparative fit index, goodness of fit index, and root mean square error of approximation were used as indices of goodness of fit. The convergent validity was judged from the average variance extracted and the composite reliability, and the internal consistency was estimated by Cronbach standardized alpha. The stability of the models was evaluated by multigroup analysis in independent samples (test and validation) and between users and nonusers of dental prosthesis. Results: We found best-fitting models for the OHIP-14 and among dental prosthesis users. The convergent validity was below adequate values for the factors “functional limitation” and “physical pain” for the complete version and for the factors “functional limitation” and “psychological discomfort” for the OHIP-14. Values of composite reliability and internal consistency were below adequate in the OHIP-14 for the factors “functional limitation” and “psychological discomfort.” We detected strong invariance between test and validation samples of the full version and weak invariance for OHIP-14. The models for users and nonusers of dental prosthesis were not invariant for both versions. Conclusion: The reduced version of the OHIP was parsimonious, reliable, and valid to capture the construct “impact of oral health on quality of life,” which was more pronounced in prosthesis users.
- Reliability and validity of self-reported burnout in college students: A cross randomized comparison of paper-and-pencil vs. online administrationPublication . Campos, Juliana Alvares Duarte Bonini; Zucoloto, Miriane Lucindo; Bonafé, Fernanda Salloumé Sampaio; Jordani, Paula Cristina; Maroco, JoãoInternet data collection is becoming increasingly popular in all research fields dealing with human perceptions, behaviors and opinions. Advantages of internet data collection, when compared to the traditional paper-and-pencil format, include reduced costs, automatic database creation, and the absence of researcher-related bias effects, such as availability and complete anonymity. However, the validity and reliability of internet gathered data must be established, in comparison to the usual paper-and-pencil accepted formats, before an inferential analysis can be done. In this study, we compared questionnaire data gathered from the internet with that from the traditional paper-and-pencil in a sample of college students. The questionnaires used were the Maslach Burnout Inventory – Student Survey (MBI-SS), the Oldenburg Burnout Inventory (OBI-SS) and the Copenhagen Burnout Inventory (CBI-SS). Data was gathered through a within-subject cross randomized and counterbalanced design, on both internet and paper-and-pencil formats. The results showed no interference in the application order, and a good reliability for both formats. However, concordance between answers was generally higher in the paperand- pencil format than on the internet. The factorial structure was invariant in the three burnout inventories. Data gathered in this study supports the Internet as a convenient, user-friendly, comfortable and secure data gathering method which does not affect the accepted factorial structures existent in the paper format of the three burnout inventories used.
- School engagement and burnout in a sample of brazilian studentsPublication . Zucoloto, Miriane Lucindo; Oliveira, Vanessa de; Maroco, João; Campos, Juliana Alvares Duarte BoniniObjective: Some studies have suggested that school engagement can be an ally in the prevention of psychosocial and occupational risks, to which students are exposed daily. The aim of this study is to estimate the impact of emotional, behavioral, and cognitive engagement on burnout syndrome among pharmacy undergraduate students. Methods: A total of 363 students enrolled in the pharmacy undergraduate program in the College of Pharmaceutical Sciences at Sao Paulo State University’s Araraquara Campus (UNESP) participated, 78.0% of whom were female. Mean age was 20.3 (SD = 2.7) years. The Maslach Burnout Inventory for students (MBI-SS) and the University Students School Engagement Inventory (USEI) were used. Confirmatory factor analysis was performed to assess the psychometric properties of the instruments. The data were included in a structural equation model in which burnout was considered the central construct. The impact of school engagement on burnout was based on the statistical significance of causal paths (β) evaluated by z tests (α = 5%). Results: The psychometric properties of the MBI-SS and USEI were adequate and the structural model also presented an adequate fit. Behavioral engagement (β = −0.56) and the emotional engagement (β = −0.71) explained 81.0% of burnout variability in the sample. Cognitive engagement was not found to contribute significantly. This data provides evidence of the impact of school engagement on burnout that can be used by educators and policymakers in charge of educational process. Conclusion: School engagement presented inverse and significant influence on burnout syndrome among pharmacy students.
- Síndrome de Burnout em graduandos de OdontologiaPublication . Campos, Juliana Alvares Duarte Bonini; Jordani, Paula Cristina; Zucoloto, Miriane Lucindo; Bonafé, Fernanda Salloumé Sampaio; Maroco, JoãoThe 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.
- Validation of a measuring instrument for the perception of oral health in womenPublication . Campos, Juliana Alvares Duarte Bonini; Carrascosa, Andréa Corrêa; Zucoloto, Miriane Lucindo; Maroco, JoãoThe 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.
- Validation of the Geriatric Oral Health Assessment Index in complete denture wearersPublication . Campos, Juliana Alvares Duarte Bonini; Zucoloto, Miriane Lucindo; Geremias, R. F.; Nogueira, S. S.; Maroco, JoãoTo perform a validation of the Geriatric Oral Health Assessment Index (GOHAI) for complete denture wearers and present a proposal for estimation of perceived oral health. This is a cross-sectional study with non-probabilistic sampling. A total of 211 subjects with a mean age of 62 5 (s.d. = 11 4) years participated, being 169 female. The GOHAI was applied in a personal interview. The construct/convergent/discriminant validity was tested using structural equation modelling. Confirmatory factor analysis was used to verify the fit of three proposals of the GOHAI: three-factor, one-factor and second-order hierarchical models. The stability of the models was evaluated in independent samples. The threefactor model presented an inadequate fit, and items 3, 4 and 9 were removed. The new structure presented an acceptable fit and strong invariance in independent samples. The convergent, discriminant validity and internal consistency were below adequate. The one-factor model presented an adequate fit to the sample. Convergent validity was compromised. A strong invariance of the one-factor model was observed. To calculate the overall scores of the GOHAI factors (three-factor model) or of the oral health perception (one-factor model), a matrix of regression weights for each item in the model was presented as a suggestion. We found an adequate fit of the both structures of the GOHAI for denture wearers, but the three-factor structure was more parsimonious. We suggested considering the weights of the regression model to calculate the overall score of perceived oral health or of its factors in different samples.
