| Scientific title | CAN Stop - psychoeducation and relapse prevention for young persons with problematic cannabis use - development and evaluation of a preventive group-based training programme [Psychoedukation und Rückfallprävention für junge Menschen mit problematischem Cannabiskonsum Entwicklung und Evaluation eines Gruppenbehandlungsprogramms] |
| Study acronym | CAN Stop |
| Study objectives | We hypothesise that young cannabis users who participated at the preventive CAN Stop group training in addition to the treatment or service usually provided in the specific help provision context (e.g. drug addiction aid and youth welfare, in-patient medical context, out-patient medical context, juvenile prisons) show lower level of cannabis intake and higher levels of cannabis abstinence-related self-efficacy after the training as opposed to young cannabis users who received the usual treatment or service. |
| Ethics approval(s) | 1. Ethics Committee of the Chamber of Physicians Hamburg approved on 3rd March 2009 (ref: PV3086) 2. Ethics Committee of the Schleswig-Holstein Chamber of Physicians approved on 6th May 2009 (ref: AZ 41/09) 3. Ethics Committee of the Chamber of Physicians North Rhine approved on 29th January 2010 (ref: 2009366) 4. Ethics Committee of the Chamber of Physicians Hesse approved on 2nd August 2010 (ref: MC 168/2010) |
| Health condition(s) or problem(s) studied | Problematic cannabis use |
| Intervention | The CAN Stop group training consists of eight group sessions of 90 minutes. Groups consist of six to ten young cannabis users and one or two trainers. The training's rationale is based on behavioural therapeutic and motivational interviewing elements. It encompasses consumer or craving diaries, the work with social and emotional context variables and potential triggers as well as the elaboration of alternative behaviour strategies and the activation of participants resources. Generally and for motivational reasons, it is left open to participants within the training whether they want to reduce or stop their cannabis use. However, certain settings at which the training is tested officially require absolute consume stops (e.g. prisons), yet this is a characteristic of the respective institution and not of the training itself. After completing the CAN Stop training, certificates are handed out to participants who, participated at least at five out of eight group training sessions, for further gratification. If within a group, only three or less participants remain after other participants dropped out of the group, the group is not further continued. Control participants receive the respective treatment as usual, which the setting, the person is in usually provides. After the follow-up assessment, participants are invited to take part at a CAN Stop group training if they wish to attend. Timepoints: t0 (pre) = before the training/ treatment as usual t1 (post) = after the training/ treatment as usual which is 3 months after t0 t2 (follow-up) = 6 months after t1 |
