The aim of the presentation is to analyze prisoners’ experiences of being involved in treatment programs in prison. Are there differences in the climate in a regular wing and a treatment wing? How do the prisoners describe their interactions with other prisoners in the wing and prison officers and therapists? How do the prisoners’ experience the conflict between control and rehabilitation in a treatment wing? The data consists of 20 face to face interviews with male and female prisoners in three Swedish prison security category 1 and 2. The prisoners age ranged from 23 to 45 years and their sentence ranged from 2 years to life in prison (minimum 18 years). The results show that the cultures in the treatment wings were different deepening on security category and how the treatment was organized. In two prisons the drug treatment program was run by a 12- step therapist (AA/NA) and the prison officers working in the wing were involved in the treatment. In one prison the prison officers in the wing were not involved in the treatment. The drug treatment program was based on cognitive behavioral theory and run by specially trained prison officers. The prisoners’ interactions with the prison officers were also different in the prisons depending of what kind of rituals the prisoners and staff were involved in. We can also see that the prisoners’ roles and interactions with staff are much more hostile in regular wings than in treatment wings. This can also be explained by the rituals that prisoners and staff are involved in the two types of wings. Concerning the control acts like visitations and urine samples in the treatment wings the prisoners get somewhat frustrated but at the same time they see these acts as positive to prevent drugs coming into the wing.
