3.10. Dropout
During the three-year duration of this study, only 112 students from the baseline measurement dropped out. This corresponded to 5.1% of the total number of students (N = 2203). Of the 112 dropouts, 69 were registered in some form of activity (e.g., in work, work apprenticeship, follow-up services, or maternity leave), while 26 were registered as inactive (e.g., in treatment, no structured activity, or declined follow-up), and the activity of the remaining 17 was unknown. Although the low prevalence of dropout was a good thing, it prevented us from comparing the three groups in terms of their dropout rates. Most dropout students in all groups were registered as active.
