Context

Context: Remote Electronic Voting Systems (REVS)

Note: This list contains all the constructs (and corresponding measuring variables) as defined by the authors when proposing/using/applying the theories/models in the selected context. It also includes the scales used to measure the variables.

• Construct (Theory/Model): Perceived Ease of Use (TAM)

  Indicator	Scale	Reference(s)

  A REVS that lets me vote at home, work, or other convenient place will be easy to use.	Likert 1-5, Strongly Disagree to Agree	(Yao & Murphy, 2007)

• Construct (Theory/Model): Accuracy (TAM)

  Indicator	Scale	Reference(s)
  A REVS that lets me vote at home, work, or other convenient place will Improve the efficiency of recording and counting ballots.	Likert 1-5, Strongly Disagree to Agree	(Yao & Murphy, 2007)

• Construct (Theory/Model): Availability (TAM)

  Indicator	Scale	Reference(s)
  A REVS that lets me vote at home, work, or other convenient place will be widely distributed, with just five minutes to the nearest REVS machine.	Likert 1-5, Strongly Disagree to Agree	(Yao & Murphy, 2007)
  A REVS that lets me vote at home, work, or other convenient place will be available at any convenient place.	Likert 1-5, Strongly Disagree to Agree	(Yao & Murphy, 2007)
  A REVS that lets me vote at home, work, or other convenient place will be easily found by voters at public places.	Likert 1-5, Strongly Disagree to Agree	(Yao & Murphy, 2007)

• Construct (Theory/Model): Intention to Participate (TAM)

  Indicator	Scale	Reference(s)
  If web-based voting were available, would you use it.	Likert 1-5, Strongly Disagree to Agree	(Yao & Murphy, 2007)
  If telephone voting were available, would you use it.	Likert 1-5, Strongly Disagree to Agree	(Yao & Murphy, 2007)

• Construct (Theory/Model): Mobility (TAM)

  Indicator	Scale	Reference(s)

• Construct (Theory/Model): Privacy (TAM)

  Indicator	Scale	Reference(s)
  A REVS that lets me vote at home, work, or other convenient place will prevent tracing ballots to specific voters.	Likert 1-5, Strongly Disagree to Agree	(Yao & Murphy, 2007)
