Optimization and Testing Effectiveness of a Collaborative Intervention for School Attendance Problems in Norwegian Municipalities

In this study we will investigate the effects of an intervention called Back2School, revised and adapted for Norwegian conditions on school attendance. A total of 240 participants will be recruited. All participants who have been enrolled will receive the intervention. Half of the participants will receive the intervention without delay (the experiment group), and the other half will receive it following a 13-week period (the control group). Following consent, screening for eligibility and randomization, the intervention will start with an assessment related to the individual participant and condition at the participants' school. Based on this a shared understanding and an intervention plan is developed. Over a 13-week period the youth, the family and the school, work together guided by the municipal team to increase attendance and solve problems related to this. Assessments will be carried out after the intervention and 6 months later.
