The internal consistency of these regulation of motivation scales also has been supported
in each of these studies. Within the recent college samples, coefficient alphas for these scales
ranged from .72 to .94, with most alphas greater than .80 (see Table 2). Likewise, these scales
have exhibited strong internal consistency among junior and senior high school students with
alphas ranging from .73 to .88 (see Table 2). In short, there is ample evidence indicating that the
regulation of motivation items tap into discrete underlying strategies within samples of students
from early to late adolescence.
