Although job boredom is increasingly common in the workplace, little research has examined its’ causes. Reducing job boredom has relevance to companies looking to increase the well-being of their employees in addition to their productivity. This study examined what variables are related to and predict job boredom. The Big Five personality traits and job characteristics as defined by Hackman and Oldham specifically, skill variety, task identity, task significance, autonomy and feedback from the job itself were included. A regression analysis revealed that emotional stability, openness and autonomy were significant predictors of boredom. While those were the only variables predictive of boredom, there were other significant correlations as well. These findings suggest that future research should examine the relationships between the variables in this study and control for factors to further gain insight into possible causes of boredom.

El presente trabajo de carácter psicométrico, tuvo como objetivo determinar cuáles son las evidencias de validez y confiabilidad de la Escala de Aburrimiento Laboral de Martínez Lugo y Rodríguez-Montalbán en auxiliares de almacén de 18 a 60 años (M= 27; DE= 7.70) de una empresa de Lima Metropolitana. Dentro de la muestra, el 79.7% de las personas eran hombres y el 20.3% mujeres, el muestreo utilizado fue no probabilístico accidental. Para las evidencias de validez del constructo se realizó el análisis factorial exploratorio y el análisis factorial confirmatorio, siendo el modelo tridimensional el que posee mejores índices (S-Bχ2 = 63.47; df = 17; p = .000; S-Bχ2/df = 3.73; CFI = .96; RMSEA = .052 [IC90% .039 .066]; y AIC= 117.471). La confiabilidad por consistencia interna mostró un resultado adecuado (Desvinculación: α = .825, ω = .839; Desinterés: α = .794, ω = .798; Percepción prolongada del tiempo: α = .753, ω = .758). Finalmente, se encontró correlación positiva entre la Escala de Boreout y la Escala de Aburrimiento Laboral (.75). Se concluye que el instrumento posee evidencias de estructura interna, validez del constructo, confiabilidad y convergencia con la Escala del Síndrome de Boreout. / The present work of a psychometric nature, had as a determined objective the tests of validity and reliability of the Scale of Labor Boredom of Martínez Lugo and Rodríguez-Montalbán in warehouse assistants from 18 to 60 years (M = 27; SD = 7.70) of a Lima Metropolitan company. Within the sample, 79.7% of the people were men and 20.3% women, the sampling used was accidental non-probability. For the evidence of validity of the construct, the exploratory factor analysis and confirmatory factor analysis were performed, being the three-dimensional model the one with the best indices (S-Bχ2 = 63.47; df = 17; p = .000; S-Bχ2 / df = 3.73 ; CFI = .96; RMSEA = .052 [IC90% .039 .066]; and AIC = 117.471). Reliability due to internal consistency selected an adequate result (Dissociation: α = .825, ω = .839; Disinterest: α = .794, ω = .798; Prolonged perception of time: α = .753, ω = .758). Finally, a positive correlation was found between the Boreout Scale and the Job Boredom Scale (.75). It is concluded that the instrument has evidence of internal structure, construct validity, reliability and convergence with the Boreout Syndrome Scale. / Tesis
