Current ResearchStill relatively new…But, evidence shows that SMS
interventions can work well. (Cole-Lewis & Kershaw) ◦Mostly for disease management.
Need more research and innovation using SMS for disease prevention behaviors!
So, what happened?
10 created accounts.7 responded to post-survey.5 were able to post-intervention
stress assessment.
Uh Oh…Some users having difficulty
using the program early on.…iterate, use Google Voice to
text message personal reminders to them
Did it work?In doing the behavior:
◦3 users took a deep breath each time they received the reminder!
◦Overall, 67% rate of success in triggering behavior.
In reducing stress:◦Pre and Post stress assessment survey
(scale 1-48)◦On average, participants decreased
stress level by 2 points…during FINALS week!
Mismatch in Expectation of EffortMost thought this would be simpleFor some it was extremely
difficult and their participation became a source of anxiety!
“It was stressful to sign up for the experiment”
Why?
Interface Confusion◦Perception of Difficulty was very
varible 4 users thought scheduling SMS was
extremely difficult or did not schedule; 3 thought it was easy
But the idea has potential!“I had received the messages during
finals week and it was sort of a uplifting moment for some reason. I'm not sure why. It's just not many people tell you personally ( in person or through YOUR cellphone not just a generalized email) to relax.”
“[Felt] cared for.”“The reminders were cheerful. […] I
liked them more because they came from someone I knew, a friend.”
So focus onReducing Effort on their Part Personal Touch—from a friend as
a light hearted and caring reminder, not a stress inducing reminder
Use mobile tech as a rapid prototyping tool!Best part of intervention was the
rapid iteration of the project idea to use Google Voice text message!
Other features to explore:◦MMS, voice calling, Internet
connectivity
The potential of mHealth◦Personal, portable, connected,
intelligent (Adler)◦Widely available, inexpensive, and
instant (Cole-Lewis & Kershaw)
Use those features for…◦Trigger◦Social Support◦Reinforcement/Feedback
