The authors used financial incentives to encourage healthy lifestyles in a workplace (n=406) in Northern Ireland over a 12 week period, with a follow-up check after 6 months. The participants were put either into a Incentive group (Treatment, n=199) or No-incentive (Control, n=207). Those in the Incentive group had to monitor their physical activity levels and used a loyalty card to collect points and earn rewards. The control group used their loyalty cards to monitor their activity level but could not earn points or rewards. The results found no significant difference between the groups in terms of minutes of physical activity recorded either after 12 weeks or after 6 months.
