  • No non-sense navigation (search, home)
  • Keep users engaged

Usability Testing

HekLer et al (2013) - HCI Theories

Riley et al (2011)

  • 7 out of 12 smoking interventions with theoretical basis 
  • Modest outcomes, poor adherence, short follow-up
  • Similar results from mobile tech interventions - disease management
  • Few attempts to evaluate theoretical constructs, hypotheses
  • Smoking&weight loss > disease management (in terms of theory)
