Alpha, beta, and gamma change concerning student
attitudes toward a college course were assessed before
and after the first examination in that course for an experimental
and control group. Three methodologies
were used to assess change. Those proposed by Terborg,
Howard, and Maxwell (1980) and Schmitt
(1982) produced reasonably similar conclusions concerning
change, while the methodology suggested by
Zmud and Armenakis (1978) produced relatively different
conclusions. The relative advantages and limitations
of the procedures are discussed. The major conclusion
is that much additional use and comparison of
these methodologies for assessing change is necessary
before researchers or practitioners can interpret the
practical significance of beta and gamma change or the
relative utility of various approaches to the measurement
of beta and gamma change.
