Abstract
Currently, decision makers must understand the needs that motivate workers, because
they focus on the needs that motivate to the workers. For this reason, the present study
had used the factorial analysis of the principal components, in order to configure the main
theories of content. The findings validate these assumptions showing that these theories
are interrelated, but at the same time, these differ in terms of the level of importance attributable
to the needs. In this context, it is concluded that different theories of content motivation
share a set of assumptions about human needs, even of the cluster resulting (and
relative weights of the needs) are different.
