  1. Item content for the behavioral intention items tested empirically as part of the current study. All items utilized the same 6-point fully labeled rating scale (1 = Strongly disagree, 2 = Disagree, 3 = Somewhat disagree, 4 = Somewhat agree, 5 = Agree, 6 = Strongly agree) except for Try2 and Try3, which utilized a 6-point likelihood scale (1 = Definitely not, 2 = Very unlikely, 3 = Somewhat unlikely, 4 = Somewhat likely, 5 = Very likely, 6 = Definitely)
