title: Developing a questionnaire to measure perceived attributes of eHealth innovations.
abstract: OBJECTIVE
  To design a valid and reliable questionnaire to assess perceived attributes of technology-based health education innovations.
  
  
  METHODS
  College students in 12 personal health courses reviewed a prototype eHealth intervention using a 30-item instrument based upon diffusion theory's perceived attributes of an innovation.
  
  
  RESULTS
  Principal components analysis found 5 factors accounted for 44.4% of the variance: 29.0% (relative advantage), 9.6% (simplicity), 6.5% (trialability), 5.0% (observability), and 4.4% (translatability). Internal consistency reliability ranged from .66 to .91 for the 5 factors.
  
  
  CONCLUSIONS
  The instrument can help eHealth developers determine and improve the adoption potential of their applications throughout the development cycle.
