Psychometric Properties of the Brief General Job Satisfaction Scale

One of the most important indicators of well-being is job satisfaction, which results from positive and rewarding feelings derived from work experiences, in which employees feel like a necessary part of achieving organizational outcomes. This study aimed to provide additional validity evidence for the General Job Satisfaction Scale in Brazilian samples. The sample consisted of 832 workers of both sexes (84.7% women), aged 18 to 69, predominantly from São Paulo and Rio Grande do Sul. Confirmatory factor analysis showed that the one-factor, five-item structure yielded adequate fit indices. Reliability indices (Cronbach’s Alpha and McDonald’s Omega) were satisfactory. Multigroup Confirmatory Factor Analysis demonstrated configural, metric, and scalar invariance across groups with different income levels. The instrument showed strong and positive correlations with flourishing at work. Despite the strong correlation between the variables, discriminant validity analysis indicated that the constructs are distinct. It was concluded that the instrument demonstrated adequate psychometric properties and is useful for future research and organizational assessments aimed at measuring workers’ satisfaction levels and promoting a healthier and more positive work environment.
