Assessment of the Impact of a Workplace Intervention to Reduce Prolonged Occupational Sitting Time

We aim to provide a better picture of the outcomes associated with implementing a nonpurposeful, physical activity, e-health intervention in a professional workplace. There is a need for health professionals to evaluate physical-activity-based workplace health interventions with a full range of measures. Using a social ecological model as a basis, we identify a range of subjective outcomes from 15 interviews of a cross section of participants. We document that not only did participants report a range of positive outcomes across multiple systems of influence, but they experienced some negative outcomes because of disruption to work flow and a changing of work habit. We conclude that using subjective evaluations provides a comprehensive picture of the factors that influence judgments of the efficacy of a workplace health intervention.
