Goal
Enhance understanding of personalized self-help therapy with mobile and internet
technology (in the domain of insomnia).
In particular: The development of a generic framework
that integrates persuasion strategies for sustainable behavior change and the technology to support these changes.

– Insomnia, CBT-I, mobile health, virtual coaching, persuasive technology, existing applications
• Development – Software infrastructure for registration and data collection
(mobile experiments) – App design, formalization, user interface
• User involvement – Interviewing focus groups (therapists, possible users) – Real therapy data – Scenario development – (Early stage) testing and experimental evaluation

Sleep is an essential activity for a person’s health and wellbeing

Sleep
Period of inactivity, where the body comes to rest
(nl.wikipedia)
State of lower awareness, together with lower activity of physiological processes
(WP)
State of rest of the senses and of consciousness
(Dikke Van Dale)

Sleep
1/3 of our lives, but unclear why. Some explanations, from:
- ‘repair and restore of the brain’ to
- ‘back to our origin’

Sleeping is a complicated
process
![Page 31: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/31.jpg)
Disorders
• Insomnia – onset, oversleep – primary, secondary
• Problems sleep/wake rhythm – nightshift, jetlag, ASPS, DSPS
• Other – sleep apnoea, restless legs, narcolepsy
• Parasomnia – teeth gnash, sleepwalk, nightmare, …

We concentrate on insomnia
![Page 33: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/33.jpg)
Insomnia
• A persistent difficulty initiating and/or maintaining sleep
• Primary and secondary insomnia • Mechanism badly understood • Chronic insomnia > three month • Around 10% of the population
![Page 34: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/34.jpg)
Insomnia may cause impairment of daytime functioning,
ability to concentrate, memory, and mood.
![Page 35: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/35.jpg)
Insomniacs are more likely to drop out of difficult jobs and receive fewer promotions.
![Page 36: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/36.jpg)
Insomnia may cause depression.
![Page 37: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/37.jpg)
Insomnia may cause physical illness: from a cold to rheumatism and heart
diseases
![Page 38: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/38.jpg)
Insomnia may cause death
![Page 39: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/39.jpg)
In the Netherlands 1.9 million people use hypnotics.
![Page 40: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/40.jpg)
Yearly costs of insomnia are estimated at 5 billion Euro
(in the Netherlands)
![Page 41: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/41.jpg)
So, how can this condition be
improved?
![Page 42: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/42.jpg)
First, some observations
![Page 43: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/43.jpg)
The quality of sleep does not only depend on the quality of the mattress
![Page 44: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/44.jpg)
But also on: time spent in bed,
age, health, attitudes, mental and physical activities,
![Page 45: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/45.jpg)
And: the stress in our life,
the medicines/drugs that we take, the behavior of your spouse,
![Page 46: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/46.jpg)
And on: the food that we eat,
the drinks that we drink, the circumstances in our bedroom,
…
![Page 47: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/47.jpg)
Some factors cannot be changed (e.g. age),
but many of them can (circumstances, behavior and
thoughts)
![Page 48: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/48.jpg)
How change?

What is coaching?
• awareness • change • support
![Page 72: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/72.jpg)
This is not coaching
• Disapproving ideas or behavior of coachee
• Pulling coachee to let him/her do what you want
• Indicating where the problem is • Solving the problem for the other

Cialdini: Influence: The Psychology of Persuasion
• Reciprocity - People tend to return a favour. • Commitment - If people commit, orally or in writing, to an
idea or goal, they are more likely to honour that commitment. • Social Proof - People will do things that they see other people
are doing. • Authority - People will tend to obey authority figures, even if
they are asked to perform objectionable acts. • Liking - People are easily persuaded by other people that they
like. • Scarcity - Perceived scarcity will generate demand.

What have we learned so far? Domain modeling
We are able to distinguish coaching, from sleep knowledge and communication knowledge – coaching knowledge
• build contract, evaluate results, determine state of change, send reminders, motivate coachee, negotiate exercises, …
– sleep knowledge • ‘deep sleep mostly in the beginning of sleeping period’ • ‘if SE > 75% then change(sleep_schedule)’
– communication • rules for cooperative dialogue • Gricean maximes

What have we learned so far? The ‘Unexpected Obstacles’
• PhD from Utrecht left July 1, 2013 • No proper infrastructure for mobile research
– security, privacy, … – integration of data processing (surveys, mobile, sensor), notifications
(email, …) and other services (Google store, SurveyMonkey, ...)
• Complexity of daily life, e.g.: – two people are using one phone – people are frequently interrupted on mobile phones – empty battery – wrong day implemented (after three weeks + 1) – variety of Android phones (over 4000 versions) – SurveyMonkey didn’t work on a particular day – commercial available sensors don’t work
![Page 103: Persuasive Technology for Personalized Sleep Coaching](https://reader037.fdocuments.us/reader037/viewer/2022090905/613c8b12a9aa48668d4a331b/html5/thumbnails/103.jpg)
What have we learned so far? Collaboration
Identify and involve stakeholders in early stage of the project.
In a multidisciplinary project that is developed at
different locations communication between stakeholders is extremely important.
Don’t forget your research contacts over the world.

What have we learned so far? Principles for a good sleep
• Quiet, Cleanliness and Regularity (Rust, Regelmaat, Reinheid)
• Know yourself • Increase sleep efficiency • Take care of good bedroom conditions • Use the bed only for sleep (and sex) • Eat well and do physical exercises • Improve the quality of your life • Do (only?) things that make sense • Do nothing sometimes and accept doing
nothing • Never think the same thought twice, unless the
thought is nice • Put your memory in the physical world
