RESUMEN

Objetivo: explorar la validez convergente y discriminante del maslach burnout Inventory human services survey (MBI-HSS) y del Cuestionario para la Evaluación del Síndrome de Quemarse por el Trabajo (CESQT) en población mexicana. Método: Se evaluaron 483 profesores de 100 escuelas de educación básica (primarias y secundarias) de la Ciudad de México. Se utilizó el CESQT validado en México por Gil-Monte, Unda y Sandoval (2009) y el MBI-HSS validado en población mexicana por Placencia et al. (2013), ambos son escalas likert que presentaron una confiabilidad aceptable. En el análisis de datos se realizó una matriz multirasgo-multimétodo (MRMM), que es un enfoque desarrollado por Campbell y Fiske (1959) para analizar la validez convergente y divergente. Resultados: En la MRMM se presentaron correlaciones significativas, positivas y diferentes a cero entre los mismos rasgos medidos por diferente método, Ilusión por el trabajo y realización personal (r=0,40**) desgaste psíquico y cansancio emocional (r=0,87**), e Indolencia y Despersonalización (r=0,52**) lo cual supone validez convergente, además, se pueden observar que todas las Alfas de Cronbach son aceptables salvo la de Despersonalización (subescala del MBI). El MBI-HSS presenta recurrentemente Alfas de Cronbach inferiores a 70 % en la subescala de despersonalización, en especial en población no angloparlante. Conclusión: Conforme a los resultados del presente estudio y las dificultades psicométricas presentadas por el MBI-HSS, se concluye que el CESQT es el instrumento recomendado para la evaluación del Burnout en población mexicana.

Objective: to explore the convergent and discriminant validity of the maslach burnout inventory human services survey (MBI-HSS) and the Spanish Burnout Inventory (SBI) in Mexican population. Method: 483 teachers from 100 basic education schools (primary and secondary) were evaluated in Mexico City. The mexican validated SBI by Gil-Monte, Unda and Sandoval (2009) and MBI-HSS validated in Mexican population by Placencia et al. (2013) were implemented, both are Likert scales that showed acceptable reliability. In the data analysis, a Multi-treat-Multi-method matrix (MTMM) was performed, which is an approach developed by Campbell and Fiske (1959) to analyze convergent and divergent validity. Results: MTMM showed significant positive and non-zero correlations between the same traits measured by different method, enthusiasm toward the job and personal accomplishment (r = 0,40 **) psychic exhaustion and emotional exhaustion (r = 0,87 **), and indolence and depersonalization (r = 0,52 **) which supposes convergent validity, in addition, it can be observed that all cronbach's alphas are acceptable except for depersonalization (subscale of MBI). The MBI-HSS recurrently presents cronbach's alphas lower than 0,70 on the depersonalization subscale, especially in non-English-speaking population. Conclusion: According to the results of this study and the psychometric difficulties presented by the MBI-HSS, the SBI is the recommended instrument for the evaluation of Burnout in the Mexican population.

RESUMEN

OBJECTIVE: to confirm the factorial validity of the Maslach Burnout Inventory - Human Services Survey version in a sample of health professionals from the emergency services. METHOD: a quantitative, exploratory, descriptive and analytical study. Two hundred and eighty-two health professionals participated in the study. For data collection, a sociodemographic questionnaire and the Maslach Burnout Inventory were used. The psychometric sensitivity for the MBI-HSS items was estimated by measures of central tendency, variability and the distribution shape. Internal consistency was estimated using Cronbach's alpha coefficient and the adequacy of the sample was verified using the Kaiser-Meyer-Olkin (KMO) index. As indexes for assessing the quality of fit of the model, the chi-square ratio by the degrees of freedom (χ2/DoF), the comparative fit index (CFI), the goodness of fit index (GFI), the Tucker Lewis index (TLI) and the root mean square error of approximation (RMSEA) were considered. To test data fit, the maximum likelihood method was used. RESULTS: the three-factor structure of the Maslach Burnout Inventory was confirmed. Items 9, 12, 15 and 16 had a factorial weight below what was considered appropriate and were removed from the model. The second order hierarchical model with the aforementioned modifications presented an adequate adjustment to the data and can be considered the best and most parsimonious model tested according to the information theory indexes. The internal consistency of the instrument's factors was recalculated considering the exclusion of the items and the three factors were considered adequate. CONCLUSION: the results obtained show that the Maslach Burnout Inventory is a reliable and factorially valid instrument for measuring the burnout syndrome in emergency service professionals in Brazil.

Objetivo: confirmar a validade fatorial do Maslach Bunout Inventory - versão Human Services Survey numa amostra de profissionais da saúde dos serviços de emergência. Método: estudo de abordagem quantitativa, exploratório, descritivo e analítico. Participaram do estudo 282 profissionais de saúde. Utilizou-se para a coleta de dados, um questionário sociodemográfico e o Maslach Burnout Inventory. A sensibilidade psicométrica dos itens do Maslach Bunout Inventory - versão Human Services Survey foi estimada pelas medidas de tendência central, variabilidade e forma da distribuição. A consistência interna foi estimada por meio do Coeficiente alfa de Cronbach e a adequação da amostra verificada por meio do índice de Kaiser-Meyer-Olkin (KMO). Como índices para a avaliação da qualidade de ajustamento do modelo foram considerados a razão de qui-quadrado pelos graus de liberdade (χ2 /gl), comparative fit index (CFI), goodness of fit index (GFI), índice de Tucker Lewis (TLI) e root mean square error of aproximation (RMSEA). Para testar o ajustamento dos dados utilizou-se o método de máxima verossimilhança. Resultados: confirmou-se a estrutura trifatorial do Maslach Burnout Inventory. Os itens 9, 12, 15 e 16 apresentaram peso fatorial abaixo do considerado adequado e foram removidos do modelo. O modelo hierárquico de segunda ordem, com as modificações mencionadas, apresentou ajustamento adequado aos dados e pôde ser considerado o melhor e mais parcimonioso modelo testado de acordo com os índices da teoria da informação. A consistência interna dos fatores do instrumento foi recalculada considerando-se a exclusão dos itens e foi considerada adequada nos três os fatores. Conclusão: os resultados obtidos mostram que o Maslach Burnout Inventory é um instrumento confiável e fatorialmente válido para medir a síndrome de o burnout em profissionais dos serviços de emergência no Brasil.
