Short Index of Job Satisfaction: Validity evidence from Portugal and Brazil

Abstract

Job satisfaction is an important construct that is known to be associated with workers' performance and wellbeing. As such, to properly measure it, one must use adapted measures that show adequate validity evidence for the desired context. Such measures should preferably be short to allow the parsimonious use of various measures/constructs in the same data collection. The aim of this paper is to adapt the Portuguese version for Brazil and Portugal of the Short Index of Job Satisfaction (SIJS). The SIJS is a psychometric instrument that measures job satisfaction through five items. A cross-sectional study was conducted with two multi-occupational workers samples, one from Brazil (n = 599) and one other from Portugal (n = 572). The SIJS presented good validity evidence based on its internal structure, namely dimensionality, reliability, and measurement invariance across countries and sexes. It also revealed to be positively correlated with work engagement, and quality of work life (convergent evidence). It also has shown to be negatively associated with burnout (discriminant evidence). The SIJS showed promising validity evidence. The SIJS can be useful to be used together with other instruments, due to its small number of items, producing data with good psychometric properties.

Occupational Burnout and Job Satisfaction Among Physicians in Times of COVID-19 Crisis: A Convergent Parallel Mixed-Method Study

“…higher scores indicate more levels of job satisfaction. The 5item SIJS was reported to possess good internal consistency with Cronbach α in the range of 0.82-0.89 [30]. Besides, the 5-item SIJS has shown to have a measurement invariance across countries and gender.…”

Burnout and Its Relationship with Demographic and Job-Related Variables among Dentists in Lithuania: A Cross-Sectional Study

“…Among the job-related associates, job satisfaction must be taken into consideration. Job satisfaction is an important construct that is known to be associated with workers’ performance and wellbeing [ 35 ]. A lack of job satisfaction is expected to be a predictor of burnout, although some studies conclude that there is a bidirectional and longitudinal relationship between burnout and job satisfaction [ 35 , 36 , 37 ].…”

“…Job satisfaction also correlated with work engagement or, conversely, some authors tested work engagement as a predictor of job satisfaction [ 18 , 38 , 39 , 40 , 41 ]. Despite many different psychometric instruments existing to measure the job satisfaction construct, so far few of those instruments have shown satisfactory validity evidence [ 35 ]. Indeed, this indicator should be straightforward, but it reflects key aspects of the dentist job satisfaction, such as earnings, psychological climate, relationships with colleagues and the head of the clinic, and, in general, whether such work could be recommended to young people in choosing their profession.…”
