Abstract: Objective: Job satisfaction is an important factor in the
occupational lives of workers. In this study, the relationship between
one-dimensional scale of job satisfaction and psychological wellbeing was
evaluated. Participants: A total of 1,742 workers (1,191 men and 551 women)
participated. Methods: 100-Point scale evaluating job satisfaction (0 [extremely
dissatisfied] to 100 [extremely satisfied]) and the General Health
Questionnaire, 12-item version (GHQ-12) evaluating psychological wellbeing were
used. A multiple regression analysis was then used, controlling for gender and
age. The change in the GHQ-12 and job satisfaction scores after a two-year
interval was also evaluated. Results: The mean age for the subjects was 42.2 years for the men
and 36.2 years for the women. The GHQ-12 and job satisfaction scores were
significantly correlated in each generation. The partial correlation
coefficients between the changes in the two variables, controlling for age,
were −0.395 for men and −0.435 for women (p< 0.001). A multiple
regression analysis revealed that the 100-point job satisfaction score was
associated with the GHQ-12 results (p< 0.001). The adjusted multiple
correlation coefficient was 0.275. Conclusions: The 100-point scale, which is a simple and easy tool
for evaluating job satisfaction, was significantly associated with
psychological wellbeing as judged using the GHQ-12.
