Participants' willingness to follow intervention guide- lines strictly and active participation in group-work was requested in order to stay in intervention. Development of group cohesion was encouraged. Group support was viewed as an important element in relapse prevention. Formation of support groups that would continue to meet after cessation of the meetings was encouraged. Contact times during the follow-up period were made known beforehand and participants were invited to contact the nurse through the phone at any time during the interven- tion. Ongoing support and praising adherence to preset goals is viewed fundamental to successful relapse prevention.
