This document summarizes a panel discussion on designing mobile services for health behavior change. The panelists were from Kaiser Permanente, UCSD, Intel Research, and Stanford. They discussed persuasive techniques for mobile technologies, examples of persuasive design in practice, and how tracking, reminders, and rewards can influence health behaviors. Tracking behaviors and providing feedback was seen as important. Reminders work best when they are short, contextualized, and allow user control and social elements. Rewards are more effective than punishments and work best when positive.

Stress Management
Reminder & prompt to

Response & tracking
Reinforcement
Social support

Reminders are Triggers
Break down new behaviors into small steps
Reminders can teach, guide and reinforce these steps
They’llbe asking
Small steps should be Make them feel
Fun/Interesting Is this worth it to me? Immediate
Not Annoying gratification
Easy/Achievable Can I do this? Like they rule*
Fast
Text messages are only 160 characters long
*Kathy Sierra: 'Creating Passionate Users'
17. + Reinforcement
Positive reinforcementincreases
motivation before next reminder
(regardless of success)
Use surveillancelet them know
you‟re paying attention to what they do
Reiteratewhat you want them to learn
so they remember it
18. + Use Teams to Exert Social Influence
Reminders can communicate social dynamics and create
friendly competition
Brian is your rock
Use intermittent reinforcement star relaxer for
Team Tension
Tamers with full
participation so
Good job Lynn far.
and Marcie! Can
you help Marilyn
relax? New
Congratulations on full
message coming
participation this week, Team
later today.
Harmonious! You are in first
place. New messages each
day this week.
19. + Let Them Initiate Contact Too
Push remindersdeliver frequent, randomly timed
text messages to them
Pull
remindersallow them to ask for help when
they need it
Try this: Envision going
down a slow escalator.
Count from 10 to 1 as
Help me you descend deeper
Aurrgh! I‟m Relax now into relaxation. Text
feeling tense
back how effective this
was for you (0-5)
20. + Lessons Learned about Reminders
Design for contextyour reminders enter their
life in their context
Make160 characters memorable(Read
„Made to Stick‟)
Give
them options(how, when, how
many, what type) upon sign up and in real time
Builda personal connectionby personalizing
feedback to them based on their actions. (Don‟t
say „Great job relaxing this week‟ to everyone
regardless of their actual behavior)
21. + Text Messages Make Great Reminders
Text message reminders:
Reach people where ever they are
In their context
Real time (mostly)
Can interrupt (which can be good and bad)
Exerting influence at decisive moments:
Before scheduled stressful events
When they‟re in traffic
By proximity, when they‟re near their friends or their gym or other triggering
locations
When their friends are relaxing/engaging in the target behavior
23. + Tracking & Self-Monitoring
Volitional
Event-driven (e.g. after every meal)
Practiced art (mastery…)
Prompted
Time of day (routine or tailored)
Event-driven - requires context/situation awareness
via sensor. e/Balance and my/Balance do this via
GPS

Daily Text & Picture Messages
Participant could choose the # of messages to receive & times to receive the messages
(2-5 messages per day)
Daily messages are statements or questions
Printed Materials for recommended weekly reading
Behavioral Skills, Nutrition, and PA topics (e.g. Self-monitoring, Portion Control, Routine Physical
Activity) First half provided in Binder at baseline; Second half provided at mid-point
measurement visit
Monthly Brief Counseling Calls (5-15 minutes)
Progress and counseling calls from their Health Coach addressing strategies,
social support, problem solving, etc.
Goals
Daily 500 calorie deficit (through calorie reduction and an increase in calories burned)
Self-Monitoring
Weekly weigh in (text weight) and daily food & exercise journal
Control group received mailed educational materials monthly on nutrition & physical activity.

Type of Text or Picture Message Example
Motivational Sayings Never say never, you can do it! Keep up the good work!)
Nutrition & Physical Activity Tips Try 10 baby carrots and a tablespoon of fat-free dressing for a
100 calorie snack; Want extra steps? Take the stairs today
Nutrition & Physical Activity Reminders Remember to move more today to reach your 12,000 step
goal; Be sure to practice portion control strategies at your next
meal
Short-Term Goal Reminders Think about what you can do in the next 4 hours to be healthy
Behavior Questions Have you practiced portion control strategies today? Have you
reached your 12,000 step goal today?

Closely linked to reminders and “attention technologies”
UC San Diego
Center for Wireless &
Population Health Systems
29. + Attention Technologies
Proactive – best to know when it‟s most relevant (e.g., when you‟re
being exposed)
Peripheral – shouldn‟t divert attention during “critical” tasks
Unobtrusive – shouldn‟t cause social problems
sound will be out in many cases
Rich – don‟t have to get out phone to look at it
Adaptive – changes according to your task, etc.
Redundant – if you‟re busy, miss a notification, or don‟t understand
it
From: William Griswold, PhD, UCSD
31. Rewarding vs. Punishing
+
If your mobile phone rewarded or punished you based on
your physical activities, how would it likely affect your
behavior?
32. Rewards & Punishment in Technologies
+
that Encourage Physical Activity
Fish‘n’Steps(Lin et al.) Houston (Consolvo et al.) UbiFit(Consolvo et al.)
33. +
Participants‟ reactions: Fish„n‟Steps
Happy Fish => Happy Participants
Sad Fish => System avoidance/abandonment
Reactions caused researchers to rethink the use of punishment
as a motivator
34. +
Participants‟ reactions: Houston
Small rewards felt surprisingly good
“It was kind of cool to have that
[the „*‟]. It was like, oh, a star…gosh
how the little things, you know. The
little things that count, the star.”
“It was like, yes, I rock!...and it was
fun to go back [in last 7 days] and
go, yes, there’s my star for that
day…”
35. Participant‟s reactions: UbiFit
+
It was a “gentle reminder” to be active
“It’s a nice, gentle reminder that getting off
my duff…every other day is not too much to ask.”
Barriers came up more frequently than
participants realized
“It was awful…I was like counting the days since I had
been to the gym or since I had done anything because I
had some really sick days where just stretching made
me want to throw up.”
36. +
Reward, don‟t punish
These are often intended to be long-term, discretionary
use technologies
Use positive reinforcement or rewards to encourage
change.
Do not punish the individual for lack of the desired
behavior, but try to keep her engaged in the behavior
and the technology to help her get back on track.
37. + Social Support
Opportunities for leveraging Social Support as
a Persuasive Design technique

Support
