Trial Outcomes & Findings for Effects of FDA Authorized Smokeless Tobacco Claims Among US Adults Who Smoke Cigarettes (NCT NCT06927700)

NCT ID: NCT06927700

Last Updated: 2026-03-04

Results Overview

Single item measure asking participants how harmful they think daily use of the viewed smokeless tobacco product would be to their health compared to daily cigarette smoking, (1=a lot less harmful, 2=somewhat less harmful, 3=about the same, 4=somewhat more harmful, 5=a lot more harmful). Higher scores mean thinking the viewed smokeless tobacco product is more harmful than cigarettes.

PRIMARY outcome

Timeframe: Assessed in survey measures completed immediately after viewing the study stimuli

Assessment of perceived risks of getting various smoking related diseases from using the viewed smokeless tobacco product versus from smoking cigarettes. Responses to 6 parallel questions (each asking about a different disease) were averaged together in this composite item. The question stated: "If you used only \[General Snus/Copenhagen - inserted based on brand condition\] or only cigarettes every day, which product would make it more likely that you would get": 1) lung cancer; 2) heart disease; 3) mouth cancer; 4) stroke; 5) chronic bronchitis; 6) emphysema. Response options to each were on a 5 point scale from (1=much more likely with General Snus/Copenhagen to 5=much more likely with cigarettes). Results presented here are based on the averages responses to the six items. Higher scores mean thinking risks are greater from smoking cigarettes than from using the viewed smokeless tobacco product.

SECONDARY outcome

Timeframe: Assessed in survey measures completed immediately after viewing the study stimuli

Population: Participants in Groups 1 and 4 were not asked this question (to rate the modified risk claim they saw) because their ad conditions did not include a modified risk claim (i.e., no-claim control ads).

A composite measure based on the average of 2 claim perception items, asking participants to rate whether they agreed or disagreed that the modified-risk claim in the ads they viewed was : 1) believable 2) credible. Participants responded to this while seeing the claim again on the survey screen. Response options were on a 7 point agreement scale from 1=strongly disagree to 7=strongly agree. Higher scores mean greater agreement that the claims were believable and credible.

SECONDARY outcome

Timeframe: Assessed in survey measures completed immediately after viewing the study stimuli

Population: Participants in Groups 1 and 4 were not asked this question (to rate the modified risk claim they saw) because their ad conditions did not include a modified risk claim (i.e., no-claim control ads).

A composite measure based on the average of 7 claim perception items, asking participants to rate whether they agreed or disagreed that the modified-risk claim in the ads they viewed was : 1) believable; 2) credible; 3) important; 4) new to me; 5) makes me think using this product could be less harmful to my health than smoking; 6) makes me more interested in trying this product; 7) would make me think seriously about completely switching to this product. Participants responded to this while seeing the claim again on the survey screen. Response options were on a 7 point agreement scale from 1=strongly disagree to 7=strongly agree. Higher scores mean greater agreement that participants thought the claim was persuasive/effective.
