Wireless Substitution
Ecological Momentary Assessment
• ~ 2 decades mobile health survey research
EMA 2.0 • Participant provided device
• Dynamic Remote Content Management
• Mixed-mode Integration
• Ecological (i.e., GIS) Integration • Remote Sensing (e.g., accelerometer)
Ecological Momentary Intervention
Legacy: Become and EX Mobile (iPhone)
IVR MMS SMS Email GPS
Ecological Momentary “Surveillance”
Prospective Targets
• Industry?
• Policy?
• Advocacy? • Smoker Attitudes / Beliefs?
• Tobacco Product Use Patterns?
• Smoking Initiation and/or Cessation Milestones?
• Prospective Cohort
• Large, Representative Samples • Longitudinal (but not “long”)
• Iterative • c.f., Multiphase optimization strategy (MOST)
• Adaptive
• c.f., Sequential Multiple Assignment Randomized Trial (SMART)

Opportunities
• Methodological – Reach among Priority Populations
– Prospective, Longitudinal Research Questions
– Rapid Learning Studies
• Logistical – Existing systems lower cost
– Automation lowers staffing overhead
– Improved retention / follow-up
• Collaborative – Community Outreach
– Participatory Involvement
Challenges
• Privacy
• Platform standards
• Mobile Usage Fees
• Mixed-mode effects
• Reliability / Validity
• Data Processing
• Data Analysis
Recommendations
• National Prospective Cohort
• Mobile Platform / Device Independent System Development
• Feature Phone Focus (for now)
• User Preferences Trump Mode Effects
• Mobile + GIS Integration
