Objective. In this study a series of studies to evaluate the psychometric properties of the Professional Self-Efficacy Questionnaire (AU-10) were carried out in the population of workers of Córdoba. Method. An instrumental study was carried out in which 684 workers from Córdoba participated. The answering process was evaluated, evidence of internal structure was provided by applying an exploratory and confirmatory factorial analysis, internal consistency was examined using Cronbach’s α coefficient, a study of convergence was carried out using the summarized Work Self-Efficacy Questionnaire, and groups were contrasted according to the sex and age of the participants. Results. A single underlying factor was found, which explained 53.45% of the variance of the test, this being made up of homogenous items ( α =.88). After some re-specifications to the initial model, an acceptable fit was found in the confirmatory factorial analysis ( χ ² = 135.92; p <0.00; GFI = .92; CFI = .92; RMSEA=.09). The convergence studies suggest that both questionnaires measure similar constructs ( r =.42). Finally, it was found that older and more senior workers tend to express higher beliefs of professional self- efficacy, as is theoretically expected. Conclusions. The results are promising and open a wide range of future lines of work, both practically and applied.

Basado en la “teoría cognitiva social”, el objetivo del presente trabajo es poner a prueba la invarianza estructural de un modelo sociocognitivo en donde la autoeficacia profesional desempeña un rol predictor del burnout y del engagement en el trabajo, en dos muestras independientes y heterogéneas de trabajadores españoles (N =1.406) y argentinos (N =687). Se realizó un estudio ex post facto prospectivo utilizando ecuaciones estructurales (SEM) y análisis multivariante de la varianza (MANOVA) para analizar la invarianza del modelo y determinar si existen diferencias en las variables estudiadas en función del país. Los resultados de SEM y MANOVA muestran que: a) luego de incorporaralgunas re-especificaciones al modelo de relaciones de la autoeficacia, burnout y engagement, este es invariante en las dos muestras (χ² = 209.61, gl = 16, p<.001, CFI = .94, IFI = .94, TLI = .94 RMSEA = .07); b) la autoeficacia profesional tiene una influencia negativa sobre el corazón del burnout (β Argentina = -.25 y β España = -.22, p < .001) y positiva con el corazón del engagement (β Argentina = .34 y β España = .41, p < .001), y c) existen diferencias significativas en función del país, mostrando en los trabajadores argentinos puntuaciones significativamente más altas en autoeficacia (F=107.13, p<.001). Los resultados corroboran la importancia de las creencias de autoeficacia sobre el burnout y engagement tanto en Argentina como en España.
