Small-scale, scoping study that provides a synthesis of existing knowledge about girls and young women at risk of secure care or custody, and ways in which earlier intervention strategies and alternatives to secure care and accommodation could be developed specific to their needs. The study comprised three components: a review and appraisal of existing national data sources; a review of existing empirical studies of secure care, youth custody, and community alternatives used in the UK; and a consultation with key informants from across Scotland to map the availability and use of community alternatives with girls and young women.
