Program Objectives
Health Objective: To reduce incidence of cardiovascular disease in the
target audience by 20% in 10 years from intervention initiation.
Behavioral Objective: To increase the number of steps taken weekly by the
target audience by 50% in 12 weeks.
Program Objectives, cont.
Theoretical Basis: Social Cognitive Theory
Communication Objectives: Increase target audience self efficacy to walk 10,000 steps
daily from baseline evaluations by 20% in 2 weeks after intervention initiation.
Increase target audience’s positive outcome expectations that walking 10,000 steps is good for health from baseline evaluations by 25% in 2 weeks after intervention initiation.
Decrease perception of barriers to walking 10,000 steps daily among target audience from baseline evaluations by 20% in 2 weeks after intervention initiation.
Designing Messages
Targeted messages that reflect participants’ attitudes and beliefs about walking
Limited COs to self-efficacy & positive outcome expectations
No more than two messages per day
Interactive messages
Incorporated FitBit wherever possible
Conversational/colloquial tone
Message Library
Based on user feedback, we made the following adjustments to our message library: Limited messages to 1x per day on weekends Included more goal-oriented messages Tweaked messages so they were more encouraging;
less guilt-inducing Added in more specificity

Pilot Study
4 women recruited
Pre/post surveys used to gather demographics & assess the self-efficacy to walk 10,000 steps, perceived barriers to walking 10,000 steps, & perceived benefits to health from walking 10,000 steps daily
Survey was online via Google Forms
After baseline survey, participants received introductory letter to the program.
Participants were asked to wear the FitBit for two days for baseline walking data.
Participants were asked to wear FitBits for 14 additional days and received 2 text messages/day.
Baseline Assessment
Pre-Assessment No more than 1 text message/day Most were very confident in their ability to walk
during the workday Neutral about their ability to walk 10,000 Perceived cardiovascular benefits of walking were
positive, regardless of weight change Weather, work schedule, & time were the most
common perceived barriers
Post Program Assessment
Overall increase in steps for all participants after the program
Decline in self-efficacy to walk 10,000 steps, reinforced perceived barriers to walking 10,000 steps, & decline perceived benefits to health from walking 10,000 steps daily
However, all agree walking can be beneficial to cardiovascular health regardless of weight change.
Too many text messages delivered during the program
Participant that far exceeded 10,000 steps/day believed time was less of a barrier than those who did not reach 10,000
Recommendations
Train participants more thoroughly in FitBit use and syncing
In person brief about the WorkIt! Text program and how it works with the FitBit
Longer baseline data collection period for more accurate initial walking averages
Incremental increases in goals overtime to decrease feelings of guilt Congratulations you averaged ___ steps this week! Try to
increase your daily average by 1,000. Go to www.WorkITTxt.com for ideas
Recommendations cont.
WorkIt! staff will work with the participants to set realistic goals based on baseline data
Positive reinforcement through interactive messaging at the end of the day and week Did you meet your goal today?
No That’s OK take a few extra laps around the block before bed. Check out www.WorkITTxt.com for tips to increase your steps.
