Results Of the total sample of 140 adolescents, 66.4% (n = 93, 87,1% females) confirmed that they had committed NSSI behaviour in the year preceding treatment. From this group, significantly more girls (70.4%) than boys (48,0%) admitted to NSSI behaviour (Pearson Chi2: 4.635, df 1, p = .031). Data on NSSI behaviour were available for 102 participants post-treatment. Of these 102 patients (92.9% females), 72 (70.6%) reported NSSI at the end of the treatment. Furthermore, a small group of participants who did not report NSSI at pre-treatment, reported NSSI at follow-up (13.9%), resulting in a no NSSI group of N = 30, a NSSI group of N = 62, and a NSSI starters group of N = 10. In the group of which NSSI data were missing at t-2, eight patients reported NSSI at t-1. This non-responders group consisted of significantly more boys than the NSSI group with pre and post NSSI data did (Pearson Chi2: 6.695, df 1, p = .010). Furthermore, no significant differences in the variables of NSSI behaviour, SCL-90 scores, CERQ-scores, and SCID-II outcomes at t1 were found between the group of non-responders at t2 and the participants who completed both measurements. Comparison of NSSI groups based on personality disorders Table 2 presents the number of SCID-II personality disorders in the no NSSI, the NSSI, and the NSSI starters group at pre-treatment.

At post-treatment the differences between the NSSI group (M = 202.6, SD = 62.0), the no NSSI (M = 155.6, SD = 55.1) and the NSSI 104
