Validez convergente y discriminante del síndrome de quemarse por el trabajo en maestros mexicanos

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.

Confirmatory factorial analysis of the Maslach Burnout Inventory - Human Services Survey in health professionals in emergency services.

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.

Estudio de prevalencia del Síndrome de Quemarse por el Trabajo (SQT) y su asociación con sobrecarga y autoeficacia en maestros de primaria de la ciudad de México / Study on the prevalence of the Burnout Syndrome (BS) and its association with overload and self efficiency in elementary school teachers of Mexico city

El objetivo de este estudio fue identificar la prevalencia del Síndromede Quemarse por el Trabajo (SQT en adelante) en una muestra de 698 maestros mexicanos. Y su asociación con variables de Sobrecarga y Autoeficacia laboral. Se utilizó el Cuestionario para la Evaluación del Síndrome de Quemarse por el Trabajo para Profesionales de la Educación (CESQT-PE). La prevalencia se analizó siguiendo el procedimiento de los puntos de referencia de la escala de frecuencia de respuesta. Se encontró que el 3 por ciento de los participantes presentaba baja Ilusión por el trabajo, 37.4 por ciento puntuaciones altas en Desgaste psíquico, 4.70 por ciento altos niveles de Indolencia, y, para Culpa 9.70 por ciento. Los hombres presentaron niveles más bajos en Ilusión por el trabajo y Desgaste psíquico que las mujeres. Considerando la edad, los niveles más elevados del SQT se dieron entre los 41 y 50 años. En cuanto a la asociación con Sobrecarga se encontró una correlación negativa con Ilusión por el trabajo (-0.15); y, con Desgaste psíquico, (0.56), Indolencia (0.36) y Culpa (0.29) una correlación positiva. En cuanto a la variable de Autoeficacia, una correlación positiva con Ilusión por el trabajo (0.25) y negativa con Desgaste psíquico (-0.25), Indolencia(-0.24) y Culpa (-0.19). Se concluye sobre la necesidad de intervenir para prevenir el deterioro de la salud de los docentes.

The aim of this study was to identify the prevalence of the burnout syndrome in a sample of 698 Mexican teachers and its association with labor overload and self-efficiency. The questionnaire for theevaluation of the burnout syndrome for education professionals was used. The prevalence was analyzed by the procedure of reference points of the response scale. It was found that a 3 percent of the participants showed low enthusiasm at work; a 37.40 percent scored high in psychological exhaustion; 4.70 percent high levels of indolence, and a 9.70 percent for guilt. Men displayed lower levels of enthusiasm at work and lower psychological exhaustion than women. Regarding age, the highest levels of burnout occurred between the ages of 41 and 50 years. With regard to association with overload, a negative correlation with enthusiasm (- 0.15) was found and a positive one with psychological exhaustion, (0.56), indolence (0.36) and guilt (0.29). With regard to the self-efficiency variable, a positive correlation with enthusiasm (0.25) and a negative one with psychological exhaustion (-0.25), indolence (-0.24) and guilt (-0.19) were found. It was concluded on the need to take action to prevent impairment of teachers’ health.

Validez factorial del <> (CESQT) en una muestra de maestros mexicanos / Factorial validity of the <> (CESQT) in a sample of Mexican teachers

Since the term burnout began to be used in the mid 1970's to refer to the process of deterioration in the care and professional attention given to users of human service organizations (public service, volunteer, medical, human social service, educational organizations, etc.), a variety of instruments have been developed to measure this phenomenon. A review of the literature makes it possible to conclude that among these measurement instruments the Maslach Burnout Inventory (MBI) has been used with the greatest frequency to measure the burnout syndrome, regardless of the occupational characteristics of the sample or the source of the burnout. While the most commonly employed burnout measure has been the MBI, researchers have been troubled by some of the psychometric limitations of this scale: a number of authors have suggested that a three-factor structure might not be appropriate; some items are not associated with their factors; Cronbach's alpha values are low for the Depersonalization subscale; different versions of the instrument evaluate the same phenomenon, etc. Other instruments used to evaluate burnout (for example Burnout Measure) do not satisfactorily operationalize the definition of the syndrome. The deficiencies in the instruments used for evaluating burnout have led to the development of the <> (CESQT) (Spanish Burnout Inventory). The theoretical model underlying the CESQT is based on the concept that burnout is a response to chronic job stress that stems from problematic interpersonal work relationships, and it develops in those individuals who work with people, quite frequently in service sector professionals who are in direct contact with the end-users. It is characterized by cognitive deterioration (loss of enthusiasm toward the job), emotional deterioration, and attitudes and behaviours of indifference, indolence, withdrawal and sometimes, abusive attitudes toward the client. In some cases, feelings of guilt appear. The psychometric model of the CESQT contains twenty items distributed in four dimensions such as: 1. enthusiasm toward the job (five items), defined as the individual's desire to achieve goals at work because it is a source of personal pleasure; 2. psychological exhaustion (four items), defined as the appearance of emotional and physical exhaustion due to the fact that at work s/he must deal daily with people who present or cause problems; 3. indolence (six items), defined as the appearance of negative attitudes of indifference and cynicism toward the organization's clients; 4. guilt (five items), defined as the appearance of feelings of guilt for negative attitudes developed on the job, especially toward the people with whom s/he establishes work relationships. The purpose of this study is the validation of the CESQT in Mexican primary education teachers. A four factor model, like that of the original model presented, was hypothesized. Materials and method The sample consisted of 698 primary education public school teachers in the area of Iztapalapa of the Federal District (Iztapalapa, Mexico). With regard to gender, 133 (19.10%) were men and 541 (77.50%) women. In the remaining 24 questionnaires (3.40%) gender was not identified. The mean age was 42.49 years. The <> was applied, using the version for professionals working in education (CESQT-PE). This instrument contains 20 items distributed into four dimensions called: enthusiasm toward the job (5 items) (α=.76), psychological exhaustion (4 items) (α=.82), indolence (6 items) (α=.73), and guilt (5 items) (α=.79). Low scores on Enthusiasm toward the job, together with high scores on psychological exhaustion and indolence, as well as on guilt, indicate high levels of burnout. The questionnaire was applied in 51 schools. Results The <> was high for all the items, with values superior to .40. All of the items contributed to increasing the internal consistency of the subscales they were part of. All of the subscales presented Cronbach's alpha values superior to .70. The factorial model obtained an adequate data fit for the sample: Chi²(164) = 481.01 (p<.001), AGFI = .91, RMSEA=.055, NNFI = .91, CFI = .92, and ECVI(.60-6.16) = .86. The results confirmed the hypothesis formulated. All of the factorial loadings were significant with high values, superior to .50. All of the relationships between the dimensions of the CESQT were significant for p< .001. The subscales of the CESQT presented values of skewness and kurtosis within the range of normality, with the exception of Enthusiasm toward the job, which presented asymmetry values outside the range ± 1, although the values were not extreme (S = -1 .71, K=3.96). Discusión The purpose of the study was to analyze the psychometric quality of the CESQT and its subscales in Mexican teachers, in order to evaluate the transnational validity of the instrument. The <> values obtained for the items are relatively high, which indicates that each of the dimensions of the CESQT-PE can be considered as a lineal function of the items that make it up. Therefore, all of the items make it possible to adequately predict the score of the scale and distinguish between individuals with high vs. low scores in the respective subscales. The results confirmed the hypothesized factorial structure. The four-factor structure fit the model according to all the fit indices considered, except the Chi-square test, which is an index that depends on sample size and finds a poor model fit with large samples. Based on the results obtained, it can be concluded that the factorial model adequately reproduces the theoretical model of the CESQT. The final scale is made up of four dimensions that evaluate the cognitive impairment (lack of enthusiasm about the job), emotional and physical deterioration (Psychological exhaustion), and attitudinal deterioration (Indolence), of the individual, together with the appearance of guilt feelings. These results confirm the results obtained in Spain, Chile and Portugal, and in Mexico with a sample of doctors. The Cronbach's alpha values obtained indicate that the internal consistency is good for the four subscales, and for the entire CESQT-PE scale. The skewness and kurtosis values were also good for the subscales, as values inferior to ±1 were obtained, except for the Enthusiasm toward the job subscale. The values obtained for the percentiles recommend using the 90th percentile instead of the 66th to draw conclusions about the individuals with high levels of burnout. The results of the study contribute to the psychometric validation of the theoretical model with four dimensions originating from the questionnaire, and to the transnational validation of the instrument. These results also make it possible to conclude that the CESQT, in its version for education professionals (CESQT-PE), is a reliable and valid instrument for evaluating burnout in Mexico. A slight deficiency of the instrument in this study has to do with the skweness value obtained for the Enthusiasm toward the job subscale, although further studies are necessary before conclusions can be drawn about possible modifications.

El <> (burnout) (en adelante SQT) ha sido definido como una respuesta al estrés laboral crónico al que están sometidos los profesionales de servicio que trabajan en contacto directo con humanos. En las investigaciones realizadas sobre el SQT, el instrumento para la medición que más se ha utilizado es el Maslach Burnout Inventory (MBI). Pero, este instrumento presenta insuficiencias psicométricas, y otros instrumentos de evaluación del SQT no operacionalizan de manera adecuada la definición del síndrome. Las insuficiencias en los instrumentos utilizados en la actualidad para la evaluación del SQT han llevado al desarrollo del <> (CESQT). El CESQT está formado por cuatro dimensiones denominadas: 1. Ilusión por el trabajo, definida como el deseo del individuo de alcanzar las metas laborales porque supone una fuente de placer personal. 2. Desgaste psíquico, definida como la aparición de agotamiento emocional y físico debido a que en el trabajo se tiene que tratar a diario con personas que presentan o causan problemas. 3. Indolencia, definida como la aparición de actitudes negativas de indiferencia y cinismo hacia los clientes de la organización. 4. Culpa, definida como la aparición de sentimientos de culpa por el comportamiento y las actitudes negativas desarrolladas en el trabajo, en especial hacia las personas con la que se establecen relaciones laborales. El objetivo de este estudio es la validación del CESQT en maestros mexicanos de educación básica. Se hipotetizó un modelo de cuatro factores como el del modelo original. Material y método La muestra la formaron 698 profesores de educación primaria de escuelas públicas. Según el género, 133 participantes fueron hombres (19.10%) y 541 mujeres (77.50%). En 24 cuestionarios (3.40%) no se respondió a la pregunta sobre el género. Asimismo, se aplicó el <>, en su versión para profesionales que trabajan en la educación (CESQT-PE). Es importante señalar que bajas puntuaciones en ilusión por el trabajo (cinco reactivos, (α=.76), junto a altas puntuaciones en desgaste psíquico (cuatro reactivos, (α=.82), indolencia (seis reactivos, α=.73) y en Culpa (cinco reactivos, α=.79) indican altos niveles del SQT. El cuestionario se aplicó en 51 escuelas. Resultados Para todos los reactivos la homogeneidad corregida fue alta, con valores superiores a .40. El modelo factorial obtuvo un ajuste adecuado a los datos para la muestra: Chi²(164) = 481.01 (p<.001), AGFI = .91, RMSEA=.055, NNFI = .91, CFI = .92 y ECVI(.60-6.16) = .86. Los resultados confirmaron la hipótesis formulada. Todas las cargas factoriales resultaron significativas con valores altos, superiores a .50. Discusión Los valores de homogeneidad corregida obtenidos para los reactivos son relativamente altos, lo que indica que cada una de las dimensiones del CESQT-PE se puede considerar como una función lineal de los reactivos que la componen. Los resultados han confirmado la estructura factorial hipotetizada. La estructura de cuatro factores ha alcanzado el ajuste del modelo a través de diversos índices de ajuste considerados. Todas las dimensiones presentan valores adecuados de consistencia interna. Los valores de asimetría también han sido buenos para las subescalas, excepto para la subescala de Ilusión por el trabajo que ha excedido ligeramente el criterio de ±1. Los resultados del estudio contribuyen a la validación psicométrica del modelo teórico de cuatro dimensiones origen del cuestionario, y a la validación transnacional del instrumento, y permiten concluir que el CESQT, en su versión para profesionales de la educación (CESQT-PE), resulta un instrumento fiable y válido para evaluar el SQT en México.
