Table 2. Comparison of the number of personality disorders at the start with the total SCL-90 score pre- and post-treatment Total SCL-90 score t-1 t-2 n mean SD mean SD t p Number of 0 5 172.20 personality 1 29 240.31 disorders at 2 16 255.25 t-1 >2 6 263.50 48.90 168.20 78.84 0.15 .891 51.39 187.07 60.05 4.27 .000 40.39 198.25 70.18 3.61 .003 44.38 198.50 73.40 3.04 .029 Length of treatment and changes in the SCL-90 and the SCID-II No significant correlation was found between the length of treatment and symptom reduction on the total SCL-90 (r = 0.168; n = 64; p = 0.184). The total group was divided in three groups based on length of treatment, resulting in a less than 234 days group (N = 8), a 235-364 days group (N = 22) and a more than 365 days group (N = 32). The less than 234 days group (N = 8) was to small for analyses and had to be excluded. The two remaining groups based on length of treatment, the 235-364 days group and the more than 365 days group, were compared by using the total SCL-90 scores and the number of SCID-II personality disorders at the beginning and the end of treatment. The 235-364 days group (symptoms: n = 23, t-1: 233.00, SD = 47.76; t-2: 190.87, SD = 61.44, t = 3.68, p = .001, d = .77; personality disorders: n = 22, t-1: 1.73, SD = 1.03; t-2: .59, SD = .73, t = 4.74, p = .000, d = 1.28) and the more than 365 days (symptoms: n = 31, t-1: 247.45, SD = 55.16; t-2: 183.84, SD = 64.21, t = 5.15, p = .000, d = 1.06; personality disorders: n = 32, t-1: 1.97, SD = 1.23; t-2: .63, SD = 1.16, t = 6.29, p = .000, d = 1.12) showed approximately equal symptom and number of personality disorders reduction. No significant differences were found between the two length of treatment groups on the different SCID-II personality disorders. Predictive value of personality disorder variables on treatment outcome The scales of the pre-treatment VKP and pre-treatment SCID-II were entered in a logistic regression with age, gender and duration of treatment as control variables and SCL-90 outcome as a dependent variable. None of the independent variables contributed significantly to the outcome. 21
