The purpose of this study is to develop a new integrative theory of
motivation drawn from the existing theories and data. The method used is
a combination of meta-ethnography and grounded theory. The second phase
of the study employed a thought experiment to test the newly developed
theoretical propositions of motivational force. The first phase of the
study revealed a central phenomenon for the occurrence of motivational
force, i.e. “In Search for Anchors,” which is a result of the paradox
between freedom to choose and human vulnerability. “Freedom to choose”
is the central factor of a motivational model that includes “urge,”
“challenge,” “incentive,” and “meaning.” These five factors are
motivational sources, which have holistic-dynamic-integrative
interaction. Human vulnerability is the other side of the motivational
model that comprises risk, uncertainty, and hope that ignite
motivational force. The dynamic interaction of risk, uncertainty, and
hope is represented in a mathematical formula that produces the strength
of the force, (R – H)2 x U, which can be potrayed in a “twin-peak”
curve. The thought experiment was conducted to test the hypothetical
formula. The result shows that the “twin-peak” hypothesis is supported
but the shape of the curve is found to be not symmetrical. The data show
that hope is the strongest motivational force, therefore the formula is
modified into = (R – U)2 x H. The implication of the study and the
utility of the new theory are discussed.
