was found (see Table 3). Participants with EO disruptive behavior more often had a positive rating on ‘stability of living condition’, indicating that they functioned better compared to participants with AO disruptive behavior.
Cannabis usage prior to admission and the relationship with discharge status and general daily functioning
Two third of the participants had used cannabis prior to admission (see Table
1), which was not associated with early-onset disruptive behavior, nor with duration of treatment. Participants who had used cannabis before admission more often dropped 6 out of treatment (χ2 (1, N=196) = 7.44; p=.006). Furthermore cannabis usage prior to treatment was associated with a lower score on general daily functioning (M=4.8,
SD=2.5 versus M=6.1, SD=2.2) (t (143.65) = 3.57, p=.000) at follow-up. This indicated
that cannabis usage prior to treatment might be a confounding factor in the relation between completion of treatment and general daily functioning at follow-up. Table 3
shows that participants who had used cannabis prior to treatment, functioned significantly worse on ‘substance usage’ and ‘criminal offending’ at follow-up.
Sex and the relationship with discharge status and general daily functioning
Males and females did not differ on completion or dropout from treatment, or on cannabis usage prior to treatment, nor did they differ on duration of treatment. Males more often displayed disruptive behavior before age 12 (i.e., early-onset disruptive behavior) (χ2 (1, N=175) = 5.14; p=.023) and more males (94.9%) than females (81.6%) had offended prior to treatment (χ2 (1, N=294) = 12.66; p=.000). On general daily functioning at follow-up, females had a higher score (M=6.0, SD=2.1) than males (M=5.0, SD=2.5)(t (193) = 2.39, p=.018), indicating that female participants functioned better than the male group. As shown in Table 3, males functioned significantly worse on ‘substance usage’ and ‘criminal offending’ at follow-up. No sex differences we found on the other two components.
Withdrawals versus pushouts
No significant differences were found between withdrawals and pushouts on sex, early-onset of disruptive behavior, cannabis usage prior to admission, duration of
