Abstract
As symposium discussant, Dr. Eys will first comment on the group nature of the GMCB intervention. Does it truly differ from other interventions whose participants take part in physical activity (PA) that is led by an instructor? Could the GMCB group effect amount to simple social support or nonspecific effects of participating together with others? Second, he will offer possible indicators or measures that need to be examined in order to confirm that the group has a unique identity of sufficient strength to confirm the group is an agent of change (e.g., cohesion). Third, he will remark on his impressions of the relative effectiveness of the GMCB, its strengths, and limitations based upon the evidence presented in the symposium. Do participants really depend on the group and do they transition well from the group to self-managed PA? Finally, he will suggest other settings in which the GMCB intervention model might be employed to promote increased PA (e.g., the worksite) and the related knowledge translation challenges that may arise in such new contexts.Acknowledgments: Supported by SSHRC Canada Research Chair Funding
