  • Vitality and social functioning scores showed significant interactions with improvements in the intervention group and decline in the control group, suggesting that the social interactions in the intervention group, both with the professionals and other participants, may have significantly contributed to the reported improvements in QOL.

  • An important aspect of the performance in the intervention group may have been due to the long-time contact with the participants.

  • Nursing research implications are to determine whether increased contact with nurses and/or nurse supervised groups would continue to demonstrate improvements in QOL.


In this study, Eriksson and colleagues provide the QOL and cost-effectiveness data as part of a subanalysis of the Swedish Bjorknas study.1 The Bjorknas study was a 3-year randomised controlled trial with lifestyle interventions performed in a primary care centre. It …
