variance-covariance was met [F(6, 2507.55)= .28, p = .95]. Therefore, Wilks' Lambda
test statistic was used to interpret the MANOVA results. No significant administration
differences were found [Wilks' Lambda= .99, (3, 95)= .34, p = .80, r2 = .01]. A one-
way MANOVA was also undertaken to examine administration differences for body
dissatisfaction, drive for thinness, and perfectionism scores for Time 2. The Box's test
was not significant thus, homogeneity of variance-covariance was met [F(6, 1792.57) =
1.11, p = .35]. Therefore, Wilks' Lambda test statistic was used to interpret the
MANOVA results. No significant administration differences were found [Wilks' Lambda
=.95, (3, 66) = 1.22, p = .31, r2 = .05]. Mean and standard deviation scores for the direct
and mail administration are presented in Table 4-4.

Comparison of Time Differences
The primary purpose of this study was to examine if disordered eating correlates
differed for gymnasts between preseason and competitive season. A repeated measures
ANOVA indicated no significant time effect for social physique anxiety [F(1,65) = 1.95,
