Results Descriptives The 105 subjects attended group psychotherapy between march 2013 and October 2018, with an average number of group members of 5.0. The number of C-SRSs completed per participant ranged from 2 to 43 times (M = 22.07, SD = 10.45). The number of missed sessions (M = 3.53, SD = 4.97) was calculated by subtracting the attended sessions (M = 25.6, SD = 12.7) from number of planned sessions (M = 26.3, SD = 12.7), based on which the percentage of missed sessions per respondent was calculated. This percentage did not differ (p =.72) between completers 2.78% (SD= 0.58) and dropouts 3.27 (SD = 1.51). Of the 2832 attended sessions, 2367 C-SRS were completed (response 83.6%). Dropouts versus completers The treatment duration of the dropouts (M = 125.56 days, SD = 99.1) was significantly (t = 7.497, p < 0.001) lower than that of the completers (M = 261.91 days, SD = 63.3). Dropouts (N = 36) completed the C-SRS on average 13.42 times (SD = 11.38), and completers (N = 69) completed it on average 26.58 (SD = 6.33) times. These numbers differed significantly (t = 7.629, p < 0.001). Table 1.

No significant difference was found (t = 0.583, p = 0.577) on the first C-SRS scores for dropouts versus completers. The scores of the last session however differed significantly (t = 4.756; p < .001, Cohen’s d = 1.035) between both groups. Total C- SRS scores decreased by 0.86 points per session on average for the dropouts, while increasing by 0.18 points per session for the completers. 62
