Brief Summary

The overall aim of this research is to experimentally evaluate the extent to which reducing the size of the tobacco power wall and the number of tobacco product units displayed influences tobacco use risk in adolescents.

Outcome Measures

Primary Outcomes (4)

• Proportion at Risk for Cigarette Smoking

  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 of participants within condition).

• Proportion at Risk of Using Electronic Nicotine Delivery Devices (ENDS)

  A three item, self-report assessment: 1) If one of your best friends offered you an unflavored vaping product would you use it? 2) If one of your best friends offered you a vaping product flavored with menthol or mint, would you use it? 3) If one of your best friends offered you a vaping product flavored with fruit, candy, alcohol or non-alcohol drink, or some other sweet flavor, 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 three items are summed for a total scale score. Total scale scores are dichotomized: scores of 3 are coded as '0' (no risk) and any score greater than 3 is coded as '1' (at risk). Outcome is proportion at risk of ENDS use (number of participants at risk over number of participants within condition).

  within 5 minutes of the intervention

• Proportion at Risk of Using Smokeless Tobacco

  A three item self report assessment: : 1) If one of your best friends offered you unflavored smokeless tobacco would you use it? 2) If one of your best friends offered you smokeless tobacco flavored with flavored with menthol, mint, spearmint, or wintergreen would you use it? 3) If one of your best friends offered you smokeless tobacco flavored with fruit 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 three items are summed for a total scale score. Total scale scores are dichotomized: scores of 3 are coded as '0' (no risk) and any score greater than 3 is coded as '1' (at risk).Outcome is proportion at risk of smokeless tobacco use (number of participants at risk over number of participants within condition).

  within 5 minutes of the intervention

• Proportion at Risk of Using Little Cigar/Cigarillos (LCC)

  A three item, self report assessment: 1) If one of your best friends offered you an unflavored cigarillos/filtered cigar would you use it? 2) If one of your best friends offered you a cigarillos/filtered cigar flavored with menthol or mint would you use it? 3) If one of your best friends offered you a cigarillos/filtered cigar flavored with fruit, candy, alcohol, or some other sweet flavor, 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 three items are summed for a total scale score. Total scale scores are dichotomized: scores of 3 are coded as '0' (no risk) and any score greater than 3 is coded as '1' (at risk). Outcome is proportion at risk of LCC use (number of participants at risk over number of participants within condition).

Study Arms (3)

Control

ACTIVE COMPARATOR

The tobacco power wall and number of products appears in a typical format: large power wall with a large number of products (defined here as three large cabinets)

Behavioral: Tobacco power wall size and tobacco products displayed

Small

EXPERIMENTAL

The tobacco power wall and number of tobacco products appear in their smallest format: small power wall with a small number of products displayed (defined here as one large cabinet)

Behavioral: Tobacco power wall size and tobacco products displayed

Medium

EXPERIMENTAL

The tobacco power wall and number of tobacco products appear in a format sized between the control and small conditions: a medium sized power wall with a medium number of products displayed (defined here as two large cabinets).

Behavioral: Tobacco power wall size and tobacco products displayed

Interventions

Tobacco power wall size and tobacco products displayed BEHAVIORAL

The intervention varies the size of the tobacco power wall and number of tobacco products displayed on it.

Control; Medium; Small
