“…In Sweden (Tärnfalk & Kaldal, 2012), the Nordic countries (Lappi-Seppälä, 2011;Storgaard, 2009) and in Europe, social workers play important and complex roles in the juvenile justice system (Bradt & Bouverne-De Bie, 2009;Rap, 2015). However, contradictory conditions and vague rules cause problems for SSOs in their assessments of the child's best interests and subsequent decision-making (Leviner, 2014). In addition, the Swedish social services show low inter-professional agreement, lack of knowledge of effective intervention methods and little know-how about needs assessment, especially of children and criminal youth (Andershed & Andershed, 2016;Andrée Löfholm, Brännström, Olsson, & Hansson, 2013;Åström, Jergeby, Andershed & Tengström, 2013;Ginner Hau & Smedler, 2011a, 2011bKaunitz, 2017).…”
