Further evidence that these items reflect discrete regulation of motivation strategies was
provided in Wolters (1999b). Data gathered from 88 High School students in this study were
subjected to a principal components exploratory factor analyses. Results from these analyses
indicated that the 28 motivational regulation items included in this study could best be
represented by five factors that corresponding to five of the regulation of motivation strategies
described above. Analyses using data collected from junior high school and college students
(Wolters & Rosenthal, 2000; Wolters, 2001) indicate similar findings. With a few exceptions,
the motivational regulation scales in these studies exhibited moderately strong correlations (see
Table 3) indicating that these scales reflect similar, but not overlapping underlying theoretical
constructs.
