Notes.

Differences between pretest and posttest correlations were tested with likelihood-ratio tests, comparing the a model in which the correlation were freely estimated with a model in which it was constrained to be equal. The resulting χ2 tests all have df = 1 and a critical value (with α = .05) of 3.841; significant differences (pretest vs. posttest) are shown in bold face.
