Pre- and post-treatment personality disorders and SCL-90 Of the 62 adolescents who participated in pre- and post-treatment SCID-II interviews, 56 (90.3%) completed the SCL-90 at both points in time. A significant symptom reduction was observed (t = 5.95, p = .000). The mean t-1 total score of 241.0 (SD = 51.8) on the SCL-90 declined to 189.8 (SD = 64.8) at t-2 (d = .87, 95% CI \[33.9-68.4\]). A significant correlation was found at pre- and post- treatment between the number of SCID-II personality disorders and the total score on the SCL-90 (t-1: N = 61, F = 4.71, p = .005; t-2: N = 57, F = 10.64, p = .000) (Figure 1).

Moreover, the separate groups of SCID-II personality disorders reported significantly fewer symptoms at post-treatment in comparison to their initial levels (Table 2). The group without SCID-II personality disorders at the start of treatment reported fewer symptoms both pre- and post-treatment in comparison to the SCID-II groups, and it showed no symptom decrease (n = 5, t-1: 172.20, SD = 48.90; t-2: 168.20, SD = 78.84, t = 0.15, p = .891, d = .06, 95% CI \[-72.2-80.2\]). 20
