Proportion at Risk for Cigarette Smoking Primary · within 5 minutes of the intervention

A two item self-report assessment: 1) If one of your best friends offered you an unflavored cigarette would you use it? 2) If one of your best friends offered you a menthol cigarette would you use it? Responses to each item are made on a 10-point scale where 1 = definitely not; and 10 = definitely yes and responses across the two items are summed for a total scale score. Total scale scores are dichotomized: scores of 2 are coded as '0' (no risk) and any score greater than 2 is coded as '1' (at risk). Outcome is proportion at risk of cigarette smoking (number of participants at risk over number
