Psychometric Properties of the "Spanish Burnout Inventory" in Chilean Professionals Working to Physical Disabled People

Article excerpt

While the most commonly employed burnout measure has been the Maslach Burnout Inventory (MBI), researchers have been troubled by some of the psychometric limitations of this instrument. The aim of this study was to analyze the psychometric properties of the "Spanish Burnout Inventory" (SBI). The psychometric properties were analysed with data from a sample of 277 Chilean professionals working to physical disabled people. The psychometric properties of the SBI were examined through the following analyses: confirmatory factor analysis, reliability Cronbach's alpha, and concurrent validity with the MBI. The hypothesized four factor model obtained an adequate data fit for the sample (χ2 (164) = 285.32, p < .001, GFI = .96, RMSEA = .052, NNFI = .93, CFI = .94). Results confirmed the hypothesis formulated. The Cronbach's alpha coefficient was higher than .70 for the four scales of the instruments. Results supported the concurrent validity with the MBI. As a whole, the results of these study provided evidence on the adequate psychometric properties of the SBI for the study of burnout in the Chilean cultural context.

Keywords: burnout, Spanish Burnout Inventory, job stress, confirmatory factor analysis.

El instrumento utilizado con más frecuencia para la evaluación del síndrome de quemarse por el trabajo es el Maslach Burnout Inventory (MBI). Sin embargo, presenta algunas insuficiencias psicométricas. El objetivo del estudio fue analizar las propiedades psicométricas del "Cuestionario para la Evaluación del Síndrome de Quemarse por el Trabajo" (CESQT). La muestra estuvo formada por 277 profesionales chilenos que trabajaban hacia personas con discapacidad física. Los análisis realizados fueron: análisis factorial confirmatorio, fiabilidad alfa de Cronbach, y análisis de la validez concurrente con el MBI. El modelo de cuatro factores hipotetizado obtuvo un ajuste adecuado (χ2 (164) = 285.32, p < .001, GFI = .96, RMSEA = .052, NNFI = .93, CFI = .94). Los resultados confirmaron la hipótesis formulada. El coeficiente alfa de Cronbach obtuvo valores superiores a .70 para las cuatro escalas del cuestionario. Los resultados apoyaron la validez concurrente con el MBI. Se concluye que el CESQT presenta propiedades psicométricas adecuadas para estimar el síndrome de quemarse por el trabajo en el contexto cultural chileno.

Palabras clave: síndrome de quemarse por el trabajo, CESQT, estrés laboral, análisis factorial confirmatorio.

Social, economic and technological changes have resulted in a new context for occupational organizations nowadays, causing a series of psychosocial problems particularly in issues related to job stress considered one of the main disorders affecting people's physical and physic health (Jawahar, Stone, & Kisamore, 2007). Within this general framework, health problems coming from job stress, especially the burnout syndrome, become increasingly important to consider in the labor world because of its impact on individual's well being and its consequences in national health systems.

Burnout can be defined as a response to chronic job stress that occurs when the individual feels overwhelmed and powerless to face up to difficulties that work environment, especially the social one, presents him. A well known definition comes from Maslach and Jackson (1981), who defined burnout symptoms as: a) reduced personal accomplishment, understood as the professionals' tendency to evaluate oneself negatively, particularly their work with clients, b) emotional exhaustion, in which professionals feel they are no longer able to give of themselves at a psychological level, and c) depersonalization, defined as negative and cynical attitudes and feelings about one's clients.

In this general context, burnout has been conceptualized as a process that occurs especially among professionals working with people, or whose job involves people, but it can be also observed in other professions (Maslach, Schaufeli, & Leiter, 2001). …
