Trial Outcomes & Findings for Cigarette Pack Inserts for Smoking Cessation (NCT NCT04075682)
NCT ID: NCT04075682
Last Updated: 2024-05-13
Results Overview
A single question measured on a continuous scale (1="Not at all", worse outcome; 7="Extremely", better outcome) to assess strength of confidence to quit smoking, with average scores (range 1-7) estimated.
COMPLETED
NA
387 participants
Evaluated approximately 4-5 times a day over the 14 day study period, with analyses limited to days 2-14. Day 1 was dropped due to varying coverage of the day depending on study orientation time.

| Measure |
Standard Cigarette Packs (Control)
Participants will be provided with a 2 week supply of their preferred brand of cigarettes, with the only alteration being the small health warning message on the side of the pack, whose textual content will be the same as that used for the pictorial warning label conditions.
|
Cigarette Packs With Inserts Only
Participants will be provided with a 2 week supply of their preferred brand of cigarettes, with packs altered to include inserts with four different rotating messages to promote response efficacy beliefs (2 inserts on the benefits of cessation) or self-efficacy to quit (2 inserts with cessation tips).
Inserts with efficacy messages: Four rotating inserts (i.e., small, printed messages) with messages about cessation benefits (i.e., response efficacy) and tips to quit (i.e., self-efficacy messages) will be placed inside cigarette packs.
|
Cigarette Packs With Pictorial Warnings Only
Participants will be provided with a 2 week supply of their preferred brand of cigarettes, with packs altered to include four different rotating pictorial warnings showing the consequences of smoking and that cover 50% of the front and back of the pack.
Pictorial warnings on packs: Four rotating pictorial warnings illustrating the harms of smoking will be printed on labels that will placed on and cover approximately 50% of the cigarette packs.

PRIMARY outcome
Timeframe: Evaluated approximately 4-5 times a day over the 14 day study period, with analyses limited to days 2-14. Day 1 was dropped due to varying coverage of the day depending on study orientation time.Population: Analyses include repeated observations from daily cigarette surveys. Analytic samples for H6 differ due to some missing data for each moderating variable: education (control=101; insert only=84; pictorial warnings only=87; insert + pictorial warnings=88); health literacy (control=101; insert only=86; pictorial warnings only=90; insert + pictorial warnings=88); and delayed discounting (control=101; insert only=84; pictorial warnings only=88; insert + pictorial warnings=88).
A single question measured on a continuous scale (1="Not at all", worse outcome; 7="Extremely", better outcome) to assess strength of confidence to quit smoking, with average scores (range 1-7) estimated.

Due to missing data on moderators, the analytic sample differs for H5 (control=101; insert only=84; pictorial warnings only=88; insert + pictorial warnings=88) and for each H6 moderating variable: education (n=101, 84, 87, and 88, respectively); health literacy (n=101, 86, 90, and 88, respectively); and delayed discounting (n=101, 84, 88, and 88, respectively).
A single question measured on a continuous scale to assess the extent of motivation to quit smoking (1="Not at all", worse outcome; 7="Extremely", better outcome), with average scores (range=1-7) estimated.

Inserts with efficacy messages: Four rotating inserts (i.e., small, printed messages) with messages about cessation benefits (i.e., response efficacy) and tips to quit (i.e., self-efficacy messages) will be placed inside cigarette packs.
Pictorial warnings on packs: Four rotating pictorial warnings illustrating the harms of smoking will be printed on labels that will placed on and cover approximately 50% of the cigarette packs.

PRIMARY outcome
Timeframe: Evaluated once each day (evening survey) over the 14 day study period, with analyses limited to days 2-14. Day 1 was dropped due to varying intervention exposure and coverage of the day, depending on study orientation time.Population: Analyses include repeated observations from evening reports. Due to missing data on moderators, the analytic sample differs for H5 (control=101; insert only=84; pictorial warnings only=88; insert + pictorial warnings=88) and for each H6 moderating variable: education (n=101, 85, 87, and 88, respectively); health literacy (n=101, 87, 90, and 88, respectively); and delayed discounting (n=101, 85, 88, and 88, respectively).
For each day, a single binary variable was derived to indicate whether the participant talked about either smoking cessation or smoking-related harms in the prior 24 hours, with the average daily percentage of this outcome estimated. Experiencing the event of talking about cessation or harms is a better outcome, as it is a predictor of cessation attempts.

For each day, responses to two questions were combined to create a binary variable for whether, in the prior 24 hours, the participant a) did not smoke a cigarette when they normally would, and/or b) stubbed out a cigarette before finishing it, with the average daily percentage of this outcome estimated. Experiencing the event of forgoing/stubbing out is a better outcome, as it is a predictor of cessation attempts.

SECONDARY outcome
Timeframe: Participants logged each cigarette smoked over the 14 day study period, with analyses limited to reports from days 2-14. Day 1 and 15 were dropped due to varying coverage of the day depending on study orientation time (Day 1) and ending (Day 15).Population: Analyses assess the sum of all cigarettes participants logged from days 2-14 of the study. Due to missing data on moderators, the analytic sample differs for H5 (control=101; insert only=84; pictorial warnings only=88; insert + pictorial warnings=88) and for each H6 moderating variable: education (n=101, 85, 87, and 88, respectively); health literacy (n=101, 87, 90, and 88, respectively); and delayed discounting (n=101, 85, 88, and 88, respectively).
Continuous variable summing the total number of cigarettes logged over the study period. Lower values represent a better outcome (i.e., fewer cigarettes smoked).
