Experimental: Mentoring program
Mentor and mentee meet at least every second week, for 2-4 h on every occasion, during 1 year (i.e., for a minimum of two school semesters). Meetings take place outside school and work hours, and the pairs choose activities of their own preferences. No monetary incentives exist, and the mentors are laymen volunteers. The program objective is to establish a safe and supportive relationship, by which the youth is assumed to benefit in social, emotional, and academic development, and as a consequence, be less prone to use alcohol and drugs.
