Two Housing First projects, one in Bergen and one in Sandnes are to be evaluated: Have these projects contributed to better housing stability and quality of life for participants with drugs- and mental health problems? Do established Housing First services reach out to the target group in a better way than ordinary available services? The evaluation is carried out on assignment from the Health Authorities of the West region. Researchers involved are Inger Lise Skog Hansen and Vidar Bakkeli.
