Repeated Measures Designs and the Sphericity Assumption.
Kogos, Stephen C., Jr.
This paper presents an overview of repeated measures designs, designs that measure one group over time, also called within-subjects designs. Both univariate and multivariate designs are discussed, and advantages and disadvantages of each of these designs are considered. The sphericity assumption is examined, and methods are presented to correct violations of this assumption. The sphericity assumption is met if all the differences between pairs of treatment condition scores are equally variable, and if variances of differences for all treatment conditions are homogenous. The paper also offers some suggestions for incorporating these statistical procedures into research in the field of counseling psychology. (SLD)
