Third, according to theory, commitment should be related to motiva-
tional force to perform and intrinsic motivation. That is. highly committed
employees are thought to be motivated to exert high levels of energy on
behalf of the organization. Based on four studies where such data were
available, some evidence emerged of a moderate relationship between the
two variables (using two different measures of motivation), with correla-
tions ranging from .35 to .45. The measure of motivational force to
perform is described by Crampon et al. (Note I) and the measure of
intrinsic motivation was taken from the Michigan Organizational Assess-
ment Package (Nadler. 1975).
