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)

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)
