Daily life support is a key success factor in efforts to support vulnerable groups in managing their own living and this is certainly true for addicts. This is a comparative study based on interviews with six daily supporters who work with addicts and six daily supporters who are working with mentally disabled clients. The purpose is to examine their experiences and their perceptions of what the work contains. What justifies the separation of the two groups and what are the consequences for the clients and for the professionals who work with daily life support for the two groups? The result is analyzed with earlier research in the area of daily life support, research concerning the development of professions and theories of social constructivism. The result shows that the categorization may has to do with the focus of the work with living support and that the daily living support for addicts often is directed towards the addicts ability to manage their own accommodation without risking the tenants to be evicted. In addition, the categorization implicates for addicts in terms of the existence of an indirect constraint embedded in the work of daily life support for addicts which is not found in the work of the mentally ill clients. Finally, it is possible to point to a significant difference in terms of consequences for the addicts in relation to the mentally ill group even if the base for the decision of categorization may be uncertain.
