Sensation Seeking	5 point scale, 1 = ‘Strongly disagree’ to 5 = ‘Strongly agree’	8	.83
Impulsivity	4 point scale, 1 = ‘Rarely/Never’ to 4 = ‘Almost Always/Always’	15	.57

Benefits versus Risks	5 point scale, 1 = ‘Risks are much greater than benefits’ to 5 = ‘Benefits are much greater than risks’	9	.67

Note. Items only answered if subject engaged in given risk behavior; thus, with numerous “N/A” responses, coefficient alpha was not appropriate.
