The systematic development of a tailored e-mail intervention for health behavior change toward increasing intentional physical activity.

Although the benefits of physical activity are well known, most adults in the United States are relatively sedentary, with about 60% of adults not regularly physically active and 25% of those not active at all. This inactivity places the population at risk for many chronic diseases. Understanding optimal ways of both communicating with and educating employees regarding intention to reduce risk of ill health and enhance well-being through physical activity was the fundamental aim of this health communication research study. The authors designed a series of theory-based, tailored e-mail messages, which were evaluated for content validity by health care experts and focus groups. Focus groups were held according to the stage-of-change level of the participants, and two clear domains emerged: persuasion and decision domains. Improving societal well-being in a cost-effective manner using e-mail remains to be seen; however, creating interventions to engineer sufficient impact on health behavior decision making is an investment worth exploring.
