SFI – The Danish National Centre for Social Research in cooperation with Rambøll Management Consulting conducts and evaluation for The National Board of Social Welfare of the government programme ‘Temporary transitionary housing with ICM-support for young homeless people’. The target group for the intervention is young homeless people with complex psychosocial support needs. The intervention aims at providing young people with a temporary stay in ordinary housing early in the course of an intervention, and with intensive social support from a floating support worker. The floating support is based on Intensive Case Management (ICM) which is an evidence-based floating support method that previously has been tested in the national homelessness strategy. After a stay in the transitional dwelling the young person is offered permanent housing. The intervention offers an alternative to staying at a homeless shelter or couch surfing at family or friends. The evaluation analyses the intervention, results, organization and implementation in the municipalities. An economic evaluation from a societal perspective is conducted. The evaluation is based on both quantitative and qualitative elements, including quantitative outcome measurement and a qualitative observation study amongst young people in the transitional housing. Lars Benjaminsen is leading SFI’s part of the evaluation. The evaluation is conducted from autumn 2015 to summer 2018. Results are published in an SFI-report.
