*Certain indications of a personality disorder according to the VKP. The presumed indications of a personality disorder according to the VKP were left out of this table.
When comparing the number of pre-treatment versus post-treatment SCID-II personality disorders, a significant decrease was found (t-1: M = 1.42, SD = 1.21, range 0-4; t-2: M = 0.48, SD = 0.78, range 0-4; z = 5.76, p = .000). The effect size for this analysis (d = 0.92, 95% CI [0.77-1.26]) was found to exceed Cohen’s (1988) convention for a large effect (d = .80). At pre-treatment, 91.8% (n = 56) of the patients had one or more personality disorders, compared to 35.4% at post-treatment (n = 22). The majority, 74.1% (n = 46) of patients, showed a decrease in the number of SCID-II personality disorders at the end of treatment; 19.4% (n = 12) retained the same number; and 6.5% (n = 4) had more personality disorders at the end of the treatment. Although clinical judgment indicated a personality disorder, at the start of treatment, six (9.6%) patients were free of any personality disorder on the SCID-II. One adolescent out of the six deteriorated to having one SCID-II personality disorder at the end.
