Genetic influences on job satisfaction are best explained using the affectivity model of disposition.
In a recent study, scientists in the United States investigated "the extent to which traits reflecting individual differences in personality and affectivity explain or mediate genetic influences on job satisfaction."
"Using estimates of the dispositional source of job satisfaction according to two dispositional frameworks - the five-factor model and positive affectivity-negative affectivity (PA-NA) - and behavioral-genetic estimates of the heritabilities of job satisfaction and the dispositional factors," R. Ilies and coauthors at Michigan State University "computed the proportion of genetic variance in job satisfaction that is explained by these trait frameworks."
The "results indicate that the affectivity model is a stronger mediator of genetic effects on job satisfaction than the five-factor model," according to the report.
"PA and NA mediate about 45% of the genetic influences on job satisfaction, whereas the five-factor model mediates approximately 24% of these genetic effects," the researchers concluded.
Ilies and colleagues published the results of their research in the Journal of Applied Psychology (On the heritability of job satisfaction: The mediating role of personality. J Appl Psychol, 2003;88(4):750-759).
