[Housing Interventions in Severe Mental Illness - International Evidence from RCTs].

Objective Housing is important among psychosocial interventions for people with severe mental disorders. What do we know about the effectiveness of housing interventions? Methods Systematic literature search for RCTs. Results Few RCTs, almost exclusively with homeless individuals were conducted. Housing stability is one of the most direct indicators of the effectiveness of housing interventions among homeless people. There are weaker or inhomogeneous findings in other outcome areas. There are no clear results yet regarding the effectiveness of different housing interventions compared with each other. Conclusions The variability in routine interventions complicates their comparison. Future studies should address the housing needs of people who are at risk of getting homeless and of people living in inadequate housing. Methodological challenges are discussed. © Georg Thieme Verlag KG Stuttgart · New York.
