Considering the separate components of general daily functioning (see Table 3), completers functioned significantly better than the dropouts on three of the four components (‘stability of living condition’, ‘daytime activities’, and ‘criminal offending’). Further, completers and dropouts did not differ in the degree of psychological distress (SCL-90-R total score) at the start and end of the treatment. Also, no differences between completers and dropouts were found on the subscales of the SCL-90-R at both measurements.
Early-onset disruptive behavior and the relationship with discharge status and general daily functioning
For 175 of the 196 participants the age of onset of the disruptive behavior could be determined (89.3% of the sample), which resulted in 122 early-onset (122/175 = 69.7%) and 53 adolescent-onset (30.3%) participants. Participants with early-onset disruptive behavior more often dropped out of treatment than participants with adolescent-onset disruptive behavior (χ2 (1, N=175) = 6.66; p=.01).
At follow-up, no significant difference was found between the mean score on general daily functioning of the early-onset group (M=5.32, SD=2.48) and the adolescent-onset group (M=5.15, SD=2.37) (t (173) = -.42, p=.674). When the separate components of general daily functioning were considered, one significant difference
