The Influence of an Initial Face-to-Face Meeting in an E-mail Delivered Physical Activity Intervention: A Single-Blind Randomized Controlled Trial

Abstract

This paper examines the influence of an initial face-to-face meeting in an e-mail delivered physical activity intervention. RMANCOVA was conducted to examine differences between e-mail and face-to-face arms in mean weekly steps adjusted for baseline steps, sex, and body mass index (BMI). Overall, 68 participants were analyzed (face-to-face: (n=35); e-mail: (n=33). Participants in the face-to-face arm walked a greater number of steps each week; however, differences between arms pre- and post-intervention were not statistically significant (F (1, 60) = 0.31, p = .5796). These findings suggest that a physical activity intervention where initial instructions are delivered via e-mail is not statistically significantly different from a face-to-face approach.
