title: Behaviour change in practice: group approaches.
abstract: Preliminary research in the treatment of obesity suggests that group interventions may be at least as effective as individual interventions, presumably due to the social support created among individuals in the group. Given that a cost-effectiveness analysis may favor groups, further research is necessary on how the benefits of group process can be maximized.
