2. Agenda
1. Challenges and Opportunities
2. Mobile Health Applications
3. Mobile Quality of Life Lab
4. Cardiovascular Disease Risk
3. Challenges and Opportunities: Scientific Rigour
Challenges
Use of unclear Behaviour Change techniques
• Not used
• Used, but not declared
• Used and declared, but poorly implemented
Lack of basis in medical evidence
• Low evidence of study effectiveness
• Lack of sensitivity analyses
Attempts at creating a review system for mobile health apps
• No definitive review framework
Opportunities
Apps can classify Behaviour Change techniques
• Using and declaring Behaviour Change taxonomies
• Ensuring the implementation adheres to the technique
Apps can declare medical evidence used in studies
• Describing the expectations and progress of studies
• Using, e.g., textual, graphical, interactive content
• e.g., with interactive tables for chronic disease risk
• Specifying sample characteristics for studies
Apps can ensure a review process before adding studies
• Ensuring the steps above
• Strictness may lead to quality
• e.g., Apple App Store
4. Challenges and Opportunities: Holistic Assessment
Challenges
Many apps fall into one of these two approaches
Focus on general lifestyle, health, and wellbeing
• Unclear effects of behaviour change interventions
Focus on preventing or managing diseases
• Contain healthy Behaviour Change interventions
• The disease is specific
Neither approach assesses the participant holistically
Opportunities
Apps can achieve both span and depth
Using validated scales for health and Quality of Life general
assessment
• e.g., World Health Organisation’s Quality of Life assessment
Using specific guidelines from health organisations
• e.g., the American Heart Association, the European Respiratory
Society, and many others
Implementing exploratory and interventional studies
• Studies can combine general and specific assessments
• Users can choose in which specific assessments to participate
5. Challenges and Opportunities: Data Dimensionality
Challenges
Many scientific studies need data that has
• Multiple variables and data sources
• High accuracy, frequency, and continuity
Few datasets integrate multiple data sources
• e.g., device-reported + lab-reported
Many datasets use less reliable sources
• Researchers tend to default to them
• e.g., self- or proxy/observer reports
Opportunities
Mobile platforms and frameworks can obtain such data
• Combine multiple data sources: device-reported and self-
reported with lab-reported
• Prioritise data sources by accuracy, frequency, and continuity
• Collect data of types that can trace multiple behavioural
markers simultaneously
• Obtain a holistic and realistic view of human daily living
Examples of frameworks on the Apple iOS platform
• HealthKit: lab- and device-reported health data
• ResearchKit: self-reported data
• AWARE: device-reported usage data
6. Challenges and Opportunities: Data Timespan
Challenges
Disease prevention studies need data that is
• Spanning over long periods of time
• Large enough to test scientific hypotheses with confidence
Yet, many studies continue to focus on
• Short-term data collection (“only within the study time frame”)
• Often several weeks
• Small samples (“whoever we can”)
• Often in the tens
Many apps are not updated, yielding
• A feeling of outdated user experience from participants
• Gaps in data collection and participant attrition
• Loss of information about the evolution of the data in time
Opportunities
Mobile platforms and frameworks can obtain such data
• Collect the data continuously and over long periods of time
• Collect the data independent of the installed apps
• Store the data onto the device and, optionally, in the cloud
• Already achieve horizontal scalability
• Release the apps from the burden of data storage
• Allows for less, and more complex, mobile health apps
Examples of frameworks on mobile platforms
• HealthKit: health data collected on Apple iOS devices
• Fit: health data collected on Google Android devices
• Fitbit, Withings, … - health-oriented activity trackers
7. Challenges and Opportunities: Data Control
Challenges
Many mobile health apps fail to provide
• Scientific grounds for collecting each data type
• Information about data location, transfer, and access
• Easy options to pause, stop, withdraw data
• Even a privacy policy!
Opportunities
Specific studies can focus on specifying the needed
• Data sources
• Data types
A mobile app that manages the studies can
• Allow participants to sign up for studies they are interested in
• Allow participants to manage the collection of each data type
• Request consent for any data transfer outside of the device
• Pseudonymise the participants
8. Challenges and Opportunities: Operational Burden
Challenges
Research mobile health apps are treated by researchers as yet
another tool for the study due to
• The app not being the main focus of the study researchers
• Difficulties with keeping apps alive between rounds of funding
• Interest, but limited resources in focusing on app quality
However, not addressing the user experience needs leads to
• Apps falling below participants’ expectations if not met
• Users leaving the app, negatively impacting the studies
• A Meetup friend calls them… “academic” apps
Opportunities
An app can provide a standardised structure
• For characterising the samples of participants
• Under the assumption of a large participant base
• For designing and conducting studies
• Exploratory
• Interventional
• For performing common non-functional tasks
• Health data collection from, e.g., device sensor monitoring
• Self-reported data from, e.g., questionnaires
• Study and data management
• Security
• Towards a familiar experience for participants and researchers
12. To our knowledge, there is no holistic app for researchers and smartphone users
to deploy and participate in evidence-based longitudinal, multidimensional
studies, using and generating high-resolution datasets to assess and then
change behaviours and improve QoL in the long-term.
13. mQoL | Mobile Quality of Life Lab: Overview
Motivation
Solve challenge in data collection by adding value for
participants and researchers.
Participants
Offer users the Quality of Life mobile lab as a holistic
tool for daily life exploration.
Researchers
Invite researchers to configure explorations, by
specifying motivations, models, schedules, and data.
14. mQoL | Mobile Quality of Life Lab: Data
Quality of Life self-reports
Explorations can correlate Quality of Life with behavioural marker data.
Demographic self-reports
Necessary for participant segmentation.
Medical self-reports
Necessary as input for, e.g., cardiovascular disease risk assessment models.
Performance reports
Monitoring daily life: explorations obtain behavioral marker data, e.g., physical
activity, sleep, and heart measurements.
Custom self-reports
Explorations specify questions relevant for their underlying studies.
