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.

Conclusion : The instrument can help eHealth developers determine and improve the adoption potential of their applications throughout the development cycle.
