Shrinking the Size of the Tobacco Power Wall

October 5, 2023 updated by: William Shadel, RAND

Shrinking the Size of the Tobacco Power Wall and Restricting the Number of Tobacco Products Displayed to Reduce Adolescent Tobacco Use

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.

Conditions

Detailed Description

This experiment will take place in the RAND StoreLab (RSL), a life-sized replica of a convenience store that we developed to evaluate how altering aspects of tobacco promotion at POS influences tobacco use risk during simulated shopping experiences. The study will use a between-subjects design, in which adolescents are randomly assigned to shop in the RSL under one of three conditions: (1) Large power wall/ multiple product units displayed; (2) Medium-sized power wall/multiple product units displayed; and (3) Small power wall/single product units displayed. We will consider the effect of these power wall alterations on risk of use of four classes of tobacco products: cigarettes, electronic nicotine delivery devices, cigarillos, and smokeless tobacco.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Control
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)
The intervention varies the size of the tobacco power wall and number of tobacco products displayed on it.
Experimental: Small
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)
The intervention varies the size of the tobacco power wall and number of tobacco products displayed on it.
Experimental: Medium
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).
The intervention varies the size of the tobacco power wall and number of tobacco products displayed on it.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Proportion at Risk for Cigarette Smoking
Time Frame: 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 of participants within condition).
within 5 minutes of the intervention
Proportion at Risk of Using Electronic Nicotine Delivery Devices (ENDS)
Time Frame: within 5 minutes of the intervention
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
Time Frame: within 5 minutes of the intervention
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)
Time Frame: within 5 minutes of the intervention
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).
