The Directorate of Norwegian Correctional Service commissioned a systematic search from The Social Research Unit at the Norwegian Knowledge Centre for the Health Services. The aim was to identify studies that investigated effects of and experiences with interventions that aimed at preventing and reducing criminal gang-involvement among young people in detention.
We conducted a systematic search for empirical studies, employing any kind of study design, in medical and social science databases. The search was conducted in March 2014. The authors independently assessed the identified references for inclusion/exclusion and discussed their assessments in pairs. We then sorted the references according to interventions and study design.
- We identified 2856 references in total. Among these, we considered 12 to be relevant according to the inclusion criteria.
- We identified one potentially relevant systematic review.
- We identified five controlled studies. These studies investigated the effect of multidisciplinary team programs, therapy and, employment.
- We did not identify any studies that qualitatively explored experiences with such programs.
We have sorted and listed all possibly relevant references, but we have neither read the papers in fulltext, critically appraised their methodological quality, nor synthesised their conclusions.
