Adaptação transcultural Portugal-Brasil do Inventário de Burnout de Maslach para estudantes

Abstract

OBJECTIVE: To perform a cross-cultural adaptation of the Portuguese version of the Maslach Burnout Inventory for students (MBI-SS), and investigate its reliability, validity and cross-cultural invariance. METHODS:The face validity involved the participation of a multidisciplinary team. Content validity was performed. The Portuguese version was completed in 2009, on the internet, by 958 Brazilian and 556 Portuguese university students from the urban area. Confi rmatory factor analysis was carried out using as fi t indices: the  2 /df, the Comparative Fit Index (CFI), the Goodness of Fit Index (GFI) and the Root Mean Square Error of Approximation (RMSEA). To verify the stability of the factor solution according to the original English version, crossvalidation was performed in 2/3 of the total sample and replicated in the remaining 1/3. Convergent validity was estimated by the average variance extracted and composite reliability. The discriminant validity was assessed, and the internal consistency was estimated by the Cronbach's alpha coeffi cient. Concurrent validity was estimated by the correlational analysis of the mean scores of the Portuguese version and the Copenhagen Burnout Inventory, and the divergent validity was compared to the Beck Depression Inventory. The invariance of the model between the Brazilian and the Portuguese samples was assessed. RESULTS:The three-factor model of Exhaustion, Disengagement and Effi cacy showed good fi t ( 2 /df = 8.498, CFI = 0.916, GFI = 0.902, RMSEA = 0.086). The factor structure was stable (:  CONCLUSIONS:The Portuguese version of the Maslach Burnout Inventory for students showed adequate reliability and validity, but its factor structure was not invariant between the countries, indicating the absence of cross-cultural stability.

Assessment of the Body Shape Concern: A Challenge

“…Considerando que a "preocupação com a forma do corpo" é uma variável latente, ou seja, que não pode ser medida diretamente, a avaliação das propriedades psicométricas dos instrumentos de medida torna-se uma estratégia indispensável (Campana & Tavares, 2009;Campos & Maroco, 2012). O Body Shape Questionnaire (BSQ) foi proposto originalmente na língua inglesa por Cooper et al (1987), a sua versão em português do Brasil foi elaborada por Cordás e Castilho (1994), e posteriormente apresentada por Di Pietro e Silveira (2009).…”

“…Cada um desses instrumentos aborda aspetos distintos em relação à imagem corporal, como por exemplo, preocupação com a forma do corpo, preocupação com o peso corporal, dismorfia corporal, estima corporal, atitude frente à alimentação, entre outros. Assim, a escolha do instrumento a ser utilizado deve ter em conta identificação dos aspetos teóricos relacionados com o constructo a ser avaliado e com as características psicométricas dos instrumentos (Campana & Tavares, 2009;Campos & Maroco, 2012).…”

“…A utilização de instrumentos válidos e confiáveis é um critério indispensável para garantir a qualidade dos resultados obtidos (Campos & Maroco, 2012). Devido à falta de consenso entre os estudos publicados na área, destaca-se a necessidade de consolidar a multidimensionalidade do constructo "imagem corporal" destacando as suas vertentes como aspetos isolados que contribuem para o entendimento da mesma.…”

Burnout in dental students: effectiveness of different methods

“…The instrument consists of 15 questions which are divided into three dimensions, Emotional Exhaustion, Cynicism and Professional Efficacy. Validation of the MBI-SS for use in Portuguese-speaking college students was conducted by Campos, Maroco 20 (2012). The Oldenburg Burnout Inventory -Student Version (OLBI-SS) 17 was originally proposed by Demerouti et al 14 (2001) in German, and consists of 16 statements with Likert-type four-point response scale (1: totally disagree to 4: totally agree).…”

Psychometric evaluation of a unified Portuguese-language version of the Body Shape Questionnaire in female university students

“…This technique can increase the accuracy of comparisons between studies, the efficacy of the discussions, and the amount of interactions between researchers. It is essential to test the validity, reliability, and stability of any new version in order to demonstrate its utility in different cultural contexts 34,35 .…”
