Table 4-2 presents Cronbach's alpha scores for the Eating Disorder Inventory-2

subscales and the Social Physique Anxiety Scale for Time 1 and Time 2 for the gymnasts

who completed both assessments and the total sample. The reliabilities for these

measures were acceptable to excellent (range = 0.71 to 0.92).

 Group Differences for Participants Who Completed Time 1 Only and Those Who
 Completed Time 1 and Time 2

 A one-way ANOVA was undertaken to examine the differences for social

physique anxiety between those participants who completed the Time 1 questionnaire

only (n = 117) and those who completed both the Time 1 and Time 2 questionnaires (n =

96). No significant Social Physique Anxiety Scale score group differences were found

[F(1, 211) = 1.28, p = .26, r2 = .01]. A one-way MANOVA was undertaken to examine if

differences for body dissatisfaction, drive for thinness, and perfectionism existed between

those participants who completed the Time 1 questionnaire only (n = 117) and those who

completed both the Time 1 and Time 2 questionnaires (n = 96). The Box's test was not

significant thus, homogeneity of variance-covariance was met [F(6, 261714.1) = .88, p =
