Impact of a Theory-Guided Encouragement Intervention on an Employee Walking Pilot Program

Abstract

This study investigated the impact of encouraging e-mails on self-efficacy, adherence, and step-count in a 10-week walking program. Using a 3 × 3 mixed design, participants randomly received task-involving/caring (n = 37), ego-involving (n = 35), or neutral (n = 34) e-mails and completed pre-/mid-/post surveys. Exercise self-efficacy increased over time, regardless of e-mail content. More of the task/care group adhered (63%) than ego (41%) or neutral groups (50%). The task/care group members who adhered reported significantly more daily-steps than ego or neutral groups. Results suggest that the theoretical framework used to guide encouragement in walking programs may impact participants’ adherence and steps.
