Description
Purpose: To evaluate the effects of a 12-week e-mail intervention promoting physical activity and nutrition, and to describe participant use and satisfaction feedback. Design: A longitudinal, randomized trial. Setting: Five large workplaces in Alberta, Canada. Participants: One thousand forty-three participants completed all three assessments, and 1263 participants in the experimental group provided use and satisfaction feedback after receiving the 12-week intervention. Intervention: Paired physical activity and nutrition messages were e-mailed weekly to the experimental group. The control group received all messages in bulk (i.e., within a single e-mail message) at the conclusion of the intervention. Measures: Self-report measures of knowledge, cognitions, and behaviors related to physical activity and nutrition were used. Satisfaction with e-mail messages was assessed at Time 2. Analysis: Planned contrasts compared the experimental group measures at Time 3 with those reported at Time 2 and with control group measures reported at Time 3. Control group measures at Time 3 were also compared with control group measures at Time 2. Results: The small intervention effects previously reported between Time 1 and Time 2 were maintained at Time 3. Providing the e-mail messages in bulk also had a significant positive effect on many of the physical activity and nutrition variables. Conclusions: E-mail offers a promising medium for promoting health-enhancing knowledge, attitudes, and behaviors. Additional research is needed to determine optimal message dose and content.
