Table 2. Between group differences across time.

Means and standard deviations of PP-cases [within-group differences are in square brackets].

We present pairwise data of PP-analyses. For this reason pre-scores may deviate from those reported in Table 1.* ITT analyses were computed with EM as method for missing values.

[*] = p ≤ .05

[**] = p ≤ .01

[***] = p ≤ .005

[****] = p ≤ .001
