This thesis was commissioned by the development unit for substance misuse care at Mainiemi rehabilitation centre. The aim of the thesis was to examine the quality of services provided by Mainiemi Rehabilitation Centre. The assessment was implemented according to the community ideology of Maxwell Jones, and using the Service Standards for Therapeutic Communities.

The thesis discusses quality and its significance in the social field. In addition, the theoretical background deals with community rehabilitation, Jones’s democratic therapeutic communities, as well as service standards for therapeutic communities.

The research was quantitative. The data were collected in March 2009 by using a structured questionnaire. The target group in this survey consisted of clients and personnel of Mainiemi Rehabilitation Centre. The data were analyzed by using the SPSS-computer programme.

The results proved that Mainiemi Rehabilitation Centre provides high quality services measured by the Service Standards for Therapeutic Communities. The rehabilitation centre has also succeeded in applying the community ideology of Maxwell Jones. Especially questions dealing with a safe atmosphere for rehabilitation and regular community meetings gave positive results. The area that needs most improvement is democracy and participation in decision-making, although the results even in this area were mainly positive.
